How can we help you?
We’ve recently encountered plenty of low-level issues and Bitcoin 101 questions. The aim of Trezor Support Team is to help our customers under all circumstances. But if you desire to learn more and it feels like really basic information, please try to find your answer online first. FAQ or manual pages are the perfect places to start your journey.
Did you try to connect your Trezor with a different cable? How about trying to replicate the issue in different browsers? Is there a problem with the internet connection? Those are one of the basic questions which we might ask you once you submit a ticket. You can take the first step ahead of us.
The Troubleshooter is an amazing, powerful and interactive tool where you can learn how to find details about your order or how to fix common issues. If it does not provide you with an answer, it reroutes you to a contact form and assists you with ticket submission.
If you would like your ticket to be resolved faster, please do not include irrelevant
information, it becomes harder to find the key data in an essay.
Pro tip: Say hi first and then write in bullet points.
Be brief, but provide us with as many details about your system as possible, like your OS, browser type, and firmware version. Sending this information in advance can drastically decrease the time needed to isolate the issue. Don’t forget to specify if you are using the Chrome extension or Trezor Bridge. Also, it would be helpful if you could sum up all the steps that you have tried.
Submitting more tickets will not get our immediate attention. Same goes for unnecessary
additional updates within the same ticket. Our Support Specialist would need to sort through all
the relevant information and find their way around your ticket. Moreover, by sending an
additional message to our Support Team, you are “updating” your ticket, which puts it back at
the end of the queue.
For security reasons, we cannot open any unsolicited attachments. Please do not send any
logs, screenshots or archives if we haven’t asked for them.
Please take a deep breath before contacting us. We definitely understand that the crypto world can be really stressful and it is absolutely understandable that you can lose your temper if you suddenly cannot access your funds. But please stay civil. Our team is composed of professionals and very dedicated crypto enthusiasts. They are doing their best to help you out and being rude will not help. On the contrary, it could distract them from assisting you.
Fun fact — 99,5% of the issues are not unique and there is a good chance that someone already had the same problem, shared it and already found a solution! Use search in our subreddit before starting a new thread.
We hope that together we can make the Trezor experience even more comfortable for you. Thank you
very much!
Your Trezor Support Team

What interface/service are you using with your Trezor device?
The list of the official software/services can be found here.
The list of the compatible Third-party software/services can be found here.
Please try to use your Trezor device with different USB cables (it's always better to use multiple cables to make sure that something important was not overlooked).
Make sure the cables are for transferring data, not only for charging purposes.
The best candidate for transferring data between devices is a USB cable that has successfully been used for transferring data from another device before.
Please avoid using USB hubs, USB adapters or USB reductions as well.
Trezor One uses Micro-USB to USB cable.
Please specify the nature of the damage.
Could you please confirm that you saw the error message ”Another U2F device was used to register in this application.” only when you were trying to use your Trezor device as a U2F token with a web service?
The message ”Another U2F device was used to register in this application” visible on your Trezor device screen/touchscreen, means that your computer is trying to use the U2F feature with some web service.
1. Your Trezor device was not registered with that web service
2. You wiped your Trezor device and used a different recovery seed
1. Please verify whether you registered your Trezor device as a U2F token with the respective web service and that there are no issues with the registration
2. In case you have more than one Trezor device with the same recovery seed and then registered one of them as U2F token, please try to use that particular Trezor device. Generally, because of the U2F mechanics, it's better to use the same device that you used for the registration (even though your other device uses the same recovery seed).
Please try the recovery procedure with your Trezor.
Never start the recovery procedure without making sure that your recovery seed is available and written down correctly.
To verify if your recovery seed is correct, please use the Dry-Run Recovery.
We are sorry for the inconvenience, please send us a message including the details about the issue and our Support Team will answer in a timely manner.
The problem is usually caused by an application that sends U2F requests everywhere, or by webpage with a faulty login form.
We have had reports that there were some problems with Etherdelta, Metamask and Ledger (because of their broken implementation of U2F protocol), for example.
Here are some links describing how to clear the cache of your browser:
Please try your Trezor device with a different computer. If everything is working with the different computer, then the problem is in your actual configuration (faulty USB ports or something else) and unfortunately, there is nothing that can be done from our side as the only possible solution is to perform the repair or use a different computer/configuration.
Checking this option is recommended.

Please avoid using USB hubs, USB adapters or USB reductions as well.
Trezor One uses Micro-USB to USB cable.
Trezor Model T uses USB-C to USB cable. Make sure the USB-C cable is connected properly to the Trezor T port, it should make a *click* sound.
Please select the option that matches your problem.
Did you perform the firmware update before this problem occurred?
Please check whether you see the Trezor device in the list of USB devices after typing and executing this command in the terminal (command line): ioreg -p IOUSB
You can find more details regarding the terminal (command line) here.
Please verify if you have correctly installed UDEV rules. Click here for more details.
Windows sometimes regards Trezor as a new device after the firmware procedure and the drivers do not update automatically.
The driver is provided by Windows itself as Trezor is the standard USB device. There is no specific driver to download.

What method are you using for communication between your Trezor device and your computer?
There are two methods:
WebUSB - The Google Chrome browser is only compatible with + Beta & Next Wallet
Trezor Bridge - (Google Chrome and Mozzila Firefox supported).
Please try your Trezor device with a different computer.

Currently the WebUSB is only working on: Beta Wallet & Next Wallet.
Trezor model T comes out of the box with WebUSB support.
Trezor One has WebUSB support from version 1.7.1 and above. If you have a lower version then you need to update your device on supported OS.
If you're not able to use WebUSB, then we will suggest using Trezor Bridge instead.
The link for downloading Trezor Bridge can be found here.
Please check whether the “trezord” process is running on your system via Task Manager or Activity Monitor (based on your operating system). Here is general information regarding Task Managers (Activity Monitors).
The above mentioned “trezord” process is necessary for communication between your Trezor device and the computer.
Also you could try to open the “Device Manager” (click here to show the details how to do it) while your Trezor device is plugged into the computer, search for the unrecognized driver (icon with a yellow triangle with "!" mark inside), click on the item with the right mouse button and choose "update drivers".
Some antiviruses, firewalls, add-ons (especially Privacy Badger or Ghostery) or VPN programs could block this process, causing Trezor to be unrecognized by your computer. Please verify those possibilities by turning off or changing the privacy settings in the respective software.
As the first troubleshooting step, please try to use your Trezor device with Beta Wallet or Next Wallet.

Is it possible that your accounts holds too many or too large transactions? Do you remember the Trezor Wallet interface warning you about this in the past?
In case you are not able to load your accounts at all, there are a few suggestions how to access them.
Suggestion #1:
Please try to use your Trezor device with Electrum wallet. Here is a guide on how to use it with our product.
If you were able to access your accounts, you should optimize them according to the advice included in this article.
Suggestion #2:
Please proceed only in emergency situations. Providing your recovery seed may compromise the whole security of your wallet and put your funds at risk.
Please try to restore your accounts with the recovery seed directly in Electrum wallet.
If you were able to access your accounts, you should immediately transfer your funds to the new wallet on your Trezor device according to the advice included in this article.
The procedure should be performed with these steps:
1. Wipe your Trezor device
2. Create the new wallet and write down the new recovery seed & “Create new wallet”.
3. Transfer the funds back to the safety of your Trezor device and optimize your accounts according to this article.
We are sorry for the inconvenience, please send us a message including the details about the issue and our Support Team will answer in a timely manner.
The message “Wrong PIN entered” on your Trezor display means that you are entering an incorrect PIN. Unfortunately, there is no other explanation for this situation.
Please take a look at the following link where it is explained how the PIN matrix works.
If you have the correct Recovery Seed, you do not need to worry. There is a way to set a new PIN by wiping your Trezor device. Your Trezor device will be also wiped after the 16th failed attempt at entering the PIN.
If you already have some funds stored there, you can restore your whole wallet with the corresponding recovery seed.
In case you wiped your Trezor device and want to access your wiped wallet again, there is no need to worry as long as you have your recovery seed for the wallet in question.
There are two recovery options in the Trezor Wallet interface:
Standard Recovery for Trezor One & Standard Recovery for Trezor Model T
Advanced Recovery (more secure method for Trezor One only)
*After the recovery, make sure to re-enable the Passphrase in advanced settings If you had it activated before.
1. Please check your internet connection (whether other webpages are working).
2. Please check whether your firewall, antivirus or VPN is blocking the Trezor Wallet interface.
3. You can check the functionality of our servers via this link. If a server is down, our team is already working on fixing this issue. Thank you for your patience.

Every processed transaction and every transaction waiting for confirmation can be found on the blockchain of the respective cryptocurrency.
Example: The Bitcoin transactions can be seen with our block explorer.
There should be several block explorers for each respective cryptocurrency.
Please take a look at the respective blockchain to verify the status of your transaction.
Firstly, we are really sorry for such an unfortunate situation.
In case you see some sent transactions which you did not confirm, there are only two possible attack vectors.
1. Your seed was compromised - Your recovery seed is the only way to restore your whole wallet (balance, accounts etc). If the attacker gets to your recovery seed, he or she can clone your wallet and operate with any of funds not protected by the passphrase.
This may happen when you keep your recovery seed digitally (on your computer, mobile device, USB drive etc) or when you provide the recovery seed to a third-party service (especially when you want to claim some forks) or when your recovery seed was stolen (someone else had physical access to it).
Please note that we cannot track the person who used your recovery seed or when and how it was compromised, because it is not leaving any trackable information.
2. Someone knows your PIN (potentially even your passphrase) - If somebody knows your sensitive data like your PIN or passphrase and has physical access to your Trezor device, he or she can freely manipulate the balance of currency stored there.
We would suggest checking who had the opportunity to manipulate your Trezor device and keep your device as evidence (for fingerprints for example).
Conclusion
Overall, the two presented scenarios are the only explanation for your situation. There is no evidence that Trezor was ever actually hacked. Therefore we recommend to starting an investigation with the police according to the facts presented in this text.
Are you experiencing problems after confirming to send the transaction (timed out, stuck browser)?
It is important to keep in mind that the Trezor hardware wallet is only responsible for signing transactions when being sent from the device. It is not responsible for confirming the transaction on the respective network.
Please select who was the receiver of this transaction.
If you provided a lower fee, it may take some time until the transaction is included in the next block (confirmed by the respective network). In some cases, when the fee is very low, the transaction might not be processed at all and will return to its source after some time.
It is important to keep in mind that the Trezor hardware wallet is only responsible for signing transactions when being sent from the device. It is not responsible for confirming the transaction on the respective network.
In this case, the transaction was probably not sent or processed at all by the respective network (blockchain) and your balance should be the same. Transactions not processed by the network are returned after some time.
Please take a look at instructions about how to create a transaction.
It is important to keep in mind that the Trezor hardware wallet is only responsible for signing transactions when being sent from the device. It is not responsible for confirming the transaction on the respective network.
Some cryptocurrencies are unfortunately using the same address formats. The developers of these cryptocurrencies are responsible for introducing their products without confusing the users and poorly distinguishing the addresses.
If you are one of these victims, you can try our recovery tool.
Please note that only certain scenarios can be resolved and the receiver needs to be your Trezor device account.
More details about how to operate with the claiming tool can be found here.
Did you verify your generated receiving address with “Show full address” function?
Also, see our article about Receiving payments.
Is it possible that your accounts holds too many or too large transactions? Do you remember the Trezor Wallet interface warning you about this in the past? You can read more about he transaction on our official wiki.
There may be some scenarios in such case.
1. The transaction was sent to someone else and that person claims that he or she did not receive anything, but the transaction is clearly confirmed by the respective blockchain (network). In this case we would suggest to verify the address provided by that person. It is possible that you were provided with a wrong address or that you mistyped the address when sending funds.
Comparing both addresses ( the one provided and the one on blockchain) is the key.
Note that some address formats are also case sensitive.
2. If the transaction was sent to some exchange account or a third-party wallet, you will need to contact the support of the respective service. Some suggestions presented in the previous point may be helpful when communicating with their support.
Please keep in mind that nobody can revert confirmed transactions. There is freedom in using cryptocurrencies. However, the freedom entails that you are the sole person responsible for your funds. It is, therefore, necessary to check carefully where you send your funds. Remember, you are your own bank.
We are sorry, but there is nothing more we can do in a situation like this.
Do you see your Trezor device status as “connected”? The information can be found under the name of your Trezor in the Trezor Wallet interface.
If you generated the receiving address under a passphrase, please make sure you are typing the correct one.
The passphrase is case sensitive, it can contain any ASCII characters and its length can be up to 50 characters.
We are sorry for the inconvenience, please send us a message including the details about the issue and our Support Team will answer in a timely manner.

Comparing the generated address for receiving your funds that is shown on your computer with the address shown on your Trezor device's screen, is one of the most crucial aspects of to making sure that this address is not changed by some malicious software, such as a specialized malware.
That is why the default option is set to “Show full address” when generating the new addresses.
More details can be found here.
We suggest comparing all the addresses you can see in your receive tab with the destination address shown on the blockchain where your funds ended.
Does the address match the address generated by the Trezor device?
If you could not find the funds in the address in the Receive tab, it could be caused by these possible scenarios:
1. You mistyped the destination address when sending the funds.
2. There is malicious software, like specialized malware, that changed the destination address - we strongly suggest running some antivirus tests on your computer.
Unfortunately, in both of the presented scenarios, the funds are lost and cannot be reverted unless you know the person who owns the addresses where the funds were sent.
3. The passphrase protection was used.
When there is a large number of unconfirmed transactions in the respective network, it is possible that not all of them will fit into the memory of the nodes immediately. It is an inherent technical limitation of Bitcoin and some other cryptocurrencies.
For instance, the transaction can get temporarily "lost" on its way to some node (it generally happens to low-fee transactions) and, therefore, it will not transmit to our servers. Hence, the unconfirmed transaction can be visible for a while, but then disappears from the Trezor Wallet interface.
If a transaction disappears from the Trezor Wallet interface after a longer time of not being confirmed, it might mean that it was canceled due to a low fee.
Once the transaction is confirmed by the network, its status will update in the Trezor Wallet interface.
It depends on the rules for the respective network (blockchain) for the particular cryptocurrency and how big the Mempool of unconfirmed transactions in this network is.
Example: There may be some tools that will let you know what the status of the Mempool is, such as this one.
In short, the transactions wait in the mempool to be “picked up” by miners. When the network is overwhelmed, the miners will prioritize the transactions with higher fees.
In such situations, the transaction can be confirmed and included into the next block or canceled by the network.
Example: It may take up to 14 days until the transaction is deemed invalid by the Bitcoin network (other cryptocurrencies may have different rules).
We are sorry for the inconvenience, please send us a message including the details about the issue and our Support Team will answer in a timely manner.
Description of the problem:
You are probably trying to send too many microtransactions at once, and your Trezor device is having problems verifying all the inputs.
Description of the problem:
One reason why you cannot create the transaction could be a wrong address type to which you are trying to send your funds.
Please make sure you are operating in the correct wallet and that you are trying to use the address format that is available for the current wallet.
It can be also caused by an extra space in the copied address. Please copy only the address.
Possible solution:
Please divide your transaction into smaller parts, until your Trezor device is able to send your transaction.
It is also good to take a look at this article, to optimize your accounts and prevent such problems in the future.
Possible solution:
Please follow these instructions to create the transaction.
Please check whether you see “Disconnected device” or “Connected device” when your Trezor is plugged in.
This status is always displayed under your Trezor name.
Please test the functionality of the right button on your Trezor device. You can try to change some of your settings to see its functionality.
To test out both your buttons, please try to to hold the left button for 5 seconds.
The screen on your Trezor should show up with the message: Do you really want to lock your Trezor?
You will have two options:
Cancel - Left button
Lock Device - Right button
If nothing showed up after the 5 second period, then your left button is not working.
Please describe the problem by selecting the appropriate category.
Additionally, please read through the articles below.
There are only two official claiming tools for the Trezor device.
Tool for: Bitcoin Cash - 2017
Tool for: Bitcoin Gold
Both are are hardforks of Bitcoin.
You can claim those cryptocurrencies only if you had some Bitcoin stored on your Trezor device before the hardforks were started (Bitcoin Cash and Bitcoin Gold launched their own blockchain).
For more details please visit these articles:
Bitcoin Cash - 2017
Bitcoin Cash - 2018 ABC -> SV
It indicates that your Trezor device was wiped during the firmware update process and then you proceeded with the new setup. This wipe happens occasionally when something goes wrong with the update procedure or when it's necessary by the nature of the update. That is why we always recommend making sure your Recovery Seed is available before you start the update procedure.
If you have your recovery seed for your original wallet (where you stored the funds), there is nothing to worry about.
There are two recovery options in the Trezor Wallet interface:
Standard Recovery for Trezor One & Standard Recovery for Trezor Model T
Advanced Recovery (more secure method for Trezor One only)
The passphrase is a great way to protect your funds with an additional layer of security, but it is necessary to know its mechanics before you start to use it.
Each passphrase creates a different wallet.
Therefore, it is necessary to type the same passphrase you used for storing your funds.
The passphrase is case sensitive, it can contain any ASCII characters and its length can be up to 50 characters.
Please, check whether the passphrase is enabled.
Leaving the passphrase field blank (not entering any characters and simply hitting “Enter”) reveals your standard wallet.
If you have performed the recovery and still see the wrong balance then it can mean two things:
1. You did not use the correct recovery seed for where your funds were stored. Please make sure that you are using the right seed.
It is also possible that you have mistyped some of the seed words. Please check your seed words with this list, where all words are presented. We would suggest searching for words that could be easily confused.
Also see this article about Commonly misspelled recovery seed words.
Your seed cannot be changed once generated, it can only be incorrectly written down.
2. You are using the passphrase protection and your funds were protected by the passphrase wallet.
The solution in this case is to enable passphrase and type the correct passphrase where you transferred your funds.
More details regarding the passphrase.
Please also check whether the passphrase is enabled.
Leaving the passphrase field blank (not entering any characters and simply hitting “Enter”) will reveal your standard wallet.
In case you wiped your Trezor device and want to access your wiped wallet again, there is no need to worry as long as you have your recovery seed for the wallet in question.
There are two recovery options in the Trezor Wallet interface:

Please, read more about this issue on our wiki.
There are basically two scenarios:

2. You have some coins stored on this Trezor device - please see our article about this.
Please let us know what error message you see on your Trezor device screen.
What do you need help with?
Description of the problem:
The "Unofficial firmware detected" message usually points out that there was a problem with the update or that you are about to use unofficial firmware, which is not recommended.
The "Broken firmware" message usually points out that there was some problem with the update.
Possible solution:
Please try to repeat the update procedure from the Trezor Wallet interface until the official firmware is successfully installed.
Here is the link for more details regarding how to start the firmware update.
Please try your device with several different USB cables (it is always better to use multiple cables to make sure that something important was not overlooked).
Make sure the cables are for transferring data, not only for charging purposes.
The best candidate for transferring data between devices is a USB cable that has successfully been used for transferring data from another device before.
Please avoid using USB hubs, USB adapters or USB reductions as well.
Trezor One uses Micro-USB to USB cable.
Trezor Model T uses USB-C to USB cable. Make sure the USB-C cable is connected properly to the Trezor T port, it should make a *click* sound.
Please try your Trezor device with a different computer. If everything is working with the different computer, then the problem is in your actual configuration (faulty USB ports or something else) and unfortunately, there is nothing that can be done from our side; the only possible solution is to perform the repair or use a different computer/configuration.
Checking this option is recommended.

If your antivirus (typically Kaspersky or Norton) is reporting our Bridge software as a virus, then it is most likely a false alarm.
There is no need to worry, as Trezor Bridge downloaded from the Trezor Wallet interface (wallet.trezor.io, beta-wallet.trezor.io) or the official source page is safe to use and it's virus free.
In conclusion, if downloaded from our official websites, it is safe to use even when detected as a virus by your antivirus.
You can help us with whitelisting our software by reporting it as a false positive to the support team of the antivirus company.
Description of the problem:
We encountered reports about this problem some time ago. It started with OS version 10.8, which set certain rules that elevated the security requirements level for all non-Apple distributed applications.

What do you need help with?
Trezor One:
Here is the link for more details regarding how to start the update.
The first update (from the bootloader version 1.3.2) should be processed by clicking on “Install firmware update” when plugging your Trezor device to the computer and visiting Trezor Wallet (wallet.trezor.io).
If there was some problem or interruption during this procedure, please start the update manually by holding both buttons on your Trezor device while it is plugged in to the computer and continue with the instructions provided on the Trezor screen and in the Trezor Wallet interface.
Trezor Model T:
Here is the link for more details regarding how to start the update.
From the bootloader version 1.3.2, when you plug in your Trezor device for the first time, the firmware update is processed by clicking on “Install firmware update” (followed by a message in the Trezor Wallet interface- wallet.trezor.io), without comparing the fingerprint.
All following updates need to be executed manually by the customer and in such cases, the fingerprint is visible.
Here is the link for more details on how to starting the update.
The fingerprint is also not case sensitive, so you do not need to worry if there is a difference in lower or upper caps characters.
When manually attempting to update the firmware, do you see on the Trezor device screen Loader 1.3.0 version?
Description of the problem:
There is a small problem with Trezor Bootloader 1.3.0, which prevents the device from being properly recognized if a user holds down the device's buttons for a longer-than-necessary amount of time. The problem can be resolved by pressing the buttons only for a short amount of time (click) when entering Bootloader mode.
Note: This only affects Trezor One only.
Possible solution:
1. Plug micro-USB into Trezor device.
2. Align USB-A to a port on your computer.
3. Plug USB-A into your computer. At the same time, click both buttons on your Trezor device.
4. The device should boot up in Bootloader mode, and the computer should recognize it.
5. If the computer does not recognize your Trezor device, please try again. Timing is essential.
It should be resolved with a click rather than with holding the buttons down. We have reports that it helps to quickly release the buttons when plugging the USB cable in.
Please try your device with several different USB cables (it is always better to use multiple cables to make sure that something important was not overlooked).
Make sure the cables are for transferring data, not only for charging.
The best candidate for transferring data between devices is a USB cable that has successfully been used for transferring data from another device before.
Please avoid using USB hubs, USB adapters or USB reductions as well.
Trezor Model One uses Micro-USB to USB cable.

Description of the problem:
If you see an error message related to the recovery process, it means that you have mistyped a seed word or that it was entered in the wrong order.
Description of the problem:
In case you have encountered the error message (The seed is INVALID!), then it means that the seed written on your recovery card is different than the seed that is actually valid in your Trezor device.
In other words, your Trezor device is not backed up and in an emergency situation (lost, non-functional or wiped Trezor after the firmware update), you will not be able to recover your wallet with this recovery seed.
Possible solution:
Please enter the seed words in the correct order according to the information visible on your Trezor display (you will be asked to enter your seed words in a shuffled order).
Here is a link for the recovery instructions
There is also a possibility that a seed word has been mistyped, please check your seed words with this list where all possible seed words are recorded. We suggest searching for words that could be easily confused.
See also this article about Commonly misspelled recovery seed words which might be helpful.
Conclusion:
If you still see an error message during or after the recovery procedure, then unfortunately, your recovery seed is not written correctly and even it pains us a lot, but we are not able to help you in this matter.
In every situation, you need to make sure that your seed is written down correctly because it is the only way to restore your wallet.
We suggest using Dry-Run Recovery to prevent such an an unfortunate situation in the future.
Possible solution:
In case you have more recovery seeds, please make sure you use the correct one that is installed in your Trezor device.
We strongly suggest transferring all your funds from the Trezor device as described here, creating a new seed and then returning your funds to the safety of your Trezor device.
Is the Trezor Wallet interface working without problems?
We are sorry for the inconvenience, please send us a message including the details about the issue and our Support Team will answer in a timely manner.
There are a few explanations for what could have happened.
1. All your entries (passwords) are tied to the respective recovery seed and if you wiped your Trezor device or it was wiped, for example by the firmware update, Trezor Password Manager would want to create a new database of passwords
2. The encrypted file with the entries saved in the service you’re using (Google Drive or Dropbox) was damaged or overwritten. We would suggest checking the capacity of the service where the file is stored.
Please select the appropriate answer.
We will try a series of steps that can resolve your problem.
Please try to restart The Password Manager.
Please check the version of your Trezor Password Manager.
If you use an older version, please download the newest one and disable the older one.
Please check the storage capacity of the service (Google Drive or Dropbox) you use and make some room if it is full.
Please try to connect your Trezor device with a different service (if you are using Google Drive, try Dropbox and vice versa).
More details can be found here.
Please also try your device with a different computer to see whether the issue is specific to your configuration.
We are sorry for the inconvenience, please send us a message including the details about the issue and our Support Team will answer in a timely manner.
Possible solution:
In case you have more recovery seeds, please make sure you use the correct one that is installed in your Trezor device.
We strongly suggest transferring all your funds from the Trezor device as described here, creating a new seed and then returning your funds to the safety of your Trezor device.
1. Please check whether the pswd file from the corresponding service (either Google Drive or Dropbox)
a) is missing
b) or is overwritten with an empty file.
The pswd file should be located at:
Google Drive - My Drive/Apps/TREZOR Password Manager
Dropbox - Apps/Trezor Password Manager/
2. If the file is missing or overwritten, then please try to restore your account. For more information on how to do it, contact Dropbox or Google support.
In that case we are really sorry, but it seems that you didn’t associate your entries (passwords) with the recovery seed you have available.
It’s unfortunate, but there is nothing that can be done from our side as it is necessary to have backed up your assets (funds and passwords as well) with the recovery seed.
You can try to return a few steps back to verify whether the problem is in the corrupted file, if you didn’t try it already.
As the first troubleshooting step, please read the information about this application here.
This is the old tool for Chrome browser designed only for the basic settings of the Trezor device.
This software is obsolete and should not be used.

Description of the problem:
If your Trezor device is not detected by your mobile device (Trezor Manager), please use this third-party tool to verify that your mobile is compatible. Your mobile device needs to have at least Android OS version 3.1 and the USB host feature must be available.
Possible solution:
With this tool, you can verify whether your mobile device has this feature available.
Certain mobile devices do have this feature, but it's not enabled by default. Please contact the support of your mobile device manufacturer to receive the necessary instructions.
Please verify if your OTG cable is connected correctly.
The OTG cable should be plugged in with the correct end, so please try switching the sides.
Please verify whether your OTG cable is faulty.
You can test it by trying to transfer some data via this cable. If it's not possible, the cable is probably defective.
We recommend trying your Trezor device with a different OTG cable (preferably with a variety of cables).
This means that your Trezor device is functional and the problem is in your mobile device.
Please repeat the previous route and suggestions. It's possible that you overlooked some important details.
Please select the corresponding application.
If the service or software that you want to use with your Trezor was not found in the list of compatible third-party products, you need to contact the developers of that product and ask them to start the integration procedure with us.

If you have an issue with the firmware update, please check out the video for reference how to do so.
If the problem still persists, please message us.
Having two devices with the identical seed is unsupported, and it will break the U2F feature.
Please try to use your Trezor device with different USB cables (it's always better to use multiple cables to make sure that something important was not overlooked).
Make sure the cables are for transferring data, not only for charging purposes.
The best candidate for transferring data between devices is a USB cable that has successfully been used for transferring data from another device before.

Once the order is shipped you will receive the notification from [email protected] email and then you can see the tracking ID in your e-shop account (https://shop.trezor.io/user/login).
This situation has several explanations.
1. You’re entering an incorrect tracking ID
2. Your order was not entered in the tracking database of the respective service yet
If you chose standard shipping for your order, the package may have left Czech Republic, and it is now untraceable until the destination country's postal service claims it.
After leaving the country of origin, the parcel travels to a foreign country where it is accepted at customs services. This is where most of the delays happen. It is unfortunate because the delivery will appear in the customer's post tracking system only after it is released by the customs.
You can receive three types of tracking ID according to the shipping method you’ve chosen for your order.
Types of tracking ID
Standard shipping: 13 characters (letters and numbers ID that starts with RR and ends with CZ)
DHL shipping: 1234567890 (ten digits ID)
UPS shipping: 18 characters (combined letters and numbers ID always starting with 1Z) příklady pro všechny tracking IDs?

1. Please contact the respective courier service or national post that handled the delivery for the possible explanation why your package is damaged.
We would suggest making photos of your package that will clearly describe its status.
2. Sometimes the package is opened by the customs. Unfortunately, we can't do anything to prevent customs from doing so as it is within their legal powers.
The customs mostly label such packages with the information that it was opened by them. When contacting the courier service or national post, you should also be informed, whether this happened.

Packaging/Device protection levels
The Trezor box is protected by holographic seals and it is also virtually impossible to open the box and device itself without breaking it (the case is sealed using ultrasound https://wiki.trezor.io/Chassis), so you would see right away if someone tampered with it.
Software protection levels
All Trezor devices are distributed without a firmware software, so you need to install it for your first use (https://wiki.trezor.io/index.php?title=Getting+started+in+5+steps&ModelType=1#Install_the_latest_firmware). If there is a firmware installed already, then that means that someone used this device before you. Obrázek
The bootloader verifies the firmware signature. The device only runs if the firmware is correctly signed by SatoshiLabs.
Our Bootloader software is write protected, as the JTAG is disabled. MCU is safeguarded by the Memory Protection Unit., that ensures you're using a valid firmware version signed by us. If not, then there is a warning message on the Trezor display.Obrázek

You can find the list of all supported coins and tokens here.
Please be aware that there is a different set of supported cryptocurrencies for each model (Trezor One and Trezor Model T) and some are supported only by the firmware.
Supported only by the firmware means, that the cryptocurrency is ready to use with the respective model, but there is no wallet (interface) to operate with it yet.
Trezor Wallet interface directly supports Bitcoin, Bitcoin Cash, Bitcoin Gold, Dash, Digibyte, Dogecoin, Ethereum, Ethereum Classic, ERC20 tokens, Litecoin, Namecoin, Vertcoin and Zcash (only transparent transactions).
Some supported cryptocurrencies can be accessed through 3rd-party wallets (for example, MyEtherWallet or MyCrypto has the integration with Trezor for using Ethereum/Ethereum Classic/ERC20 tokens).
You can refer to our Wiki for more details regarding all recommended 3rd-party wallets.
All supported coins for the respective model can be stored using one Trezor device (you do not need any additional devices).
Trezor officially supports these forks:
Bitcoin Cash (please click on the links for more information) - Wiki, Blog
Bitcoin Gold (please click on the links for more information) - Wiki, Blog
For customers:
If you would like to expand the list of the cryptocurrencies supported by our devices, please address this wish to the developers of said cryptocurrency, as we do not have the resources to develop all integrations by ourselves. It is impossible for us to have up-to-date information and to understand every existing cryptocurrency, after all.
Otherwise, please wait for our official announcement via our social media (Blog, Twitter, Reddit). Until then, the answer is going to be the same, even if you contact our support.
This answer applies to all questions regarding the unsupported cryptocurrencies.
For developers:
Developers can contact our integration specialist at integration[at]satoshilabs.com (musí se upravit na samostatnou form pod tímto emailem, jinak zcela z textu vypustit a dát link na github). Since the number of the requests is high, it may take some time until your email is answered. Thank you for your patience.

Trezor is not supporting any ICO or Airdrops.
Private key extraction:
There is no way to access your private keys unless they are exported directly from your recovery seed (https://wiki.trezor.io/Recovery_seed) (12, 18 or 24 words generated with your Trezor device). The fact that Trezor keeps these private keys isolated is actually an important security feature.
There are third-party tools capable of deriving the individual private keys from your recovery seed. However, we are not able to evaluate or guarantee the safety of such services. Therefore, we cannot recommend using them. We do not encourage Trezor users to export any private keys from the recovery seed, as it can be compromised this way.
We are afraid you will have to do your own research and make a judgment on your behalf.
In case you decide to export your seed in order to claim your individual private keys, please do so only after sending all your funds from the wallet associated with your current seed to the newly generated wallet (new seed). Afterwards. stop using that seed to avoid unnecessary risk.
In order to evaluate the support for more forks, there are several conditions that must be fulfilled by the team of developers standing behind the respective fork.
Our conditions are as follows:
1. The forked currency must be open-source, to be verifiably safe to use alongside other currencies.
2. The Bitcoin fork must have a strong, two-way replay protection. Without replay protection, you could lose your cryptocurrency when trying to use the fork.
3. The blockchain of the fork must be online, active and running. This requirement effectively means that miners are working to keep the blockchain alive and that the blocks are created at a regular period.
4. The forked coin must be backed by a development team, which regularly updates the codebase. Without this assurance, the fork might just be a quick-to-get-rich scheme at the expense of investors into the coin.
5. The cryptocurrency must be supported by reputable services, such as exchanges or wallets. No-name or previously unknown exchanges are not considered reputable.
SatoshiLabs reserve the right not to support a fork even if it addresses all the needed conditions, when we think that the support is not appropriate.
Basically, all forks that we want to support are announced through our social media. Please subscribe to our newsletter via the form that is located at the bottom of our website (http://trezor.io) and check out our blog at https://blog.trezor.io to be on top of the news!

What are the differences between the original Trezor One and the new Trezor Model T?
Trezor Model T features/improvements
Hardware
- Big touchscreen with vibrant colors (no need for physical buttons, safer recovery and entering PIN/Passphrase directly on the screen.)
- Slot for a microSD card (it will be possible to encrypt data stored on it)
- USB-C connector
- Faster CPU
Software
- Trezor Model T runs on entirely new firmware called Trezor Core. It will allow much faster development for new features, some of which will be portable back to Trezor One.
- New software stack means easier integration for new coins (more supported cryptocurrencies).
For a more detailed comparison please click on this link.

What happens to Trezor One in the future?
We will keep selling Trezor One alongside with its newer counterpart Trezor Model T.
Those two models are focusing different market segments and should do not compete.
We will keep supporting Trezor One, including security updates.
Trezor Wallet (wallet.trezor.io)
It is the official production-level, battle-tested version of the web wallet interface provided by SatoshiLabs. It is feature-conservative, meaning new functions are added at a slower pace and only after they are thoroughly tested, to ensure the highest reliability of the wallet. The purpose of this wallet is to provide a continuous and stable access to Trezor device.
Trezor Beta Wallet (beta-wallet.trezor.io)
It is a less-tested version of the web wallet interface. New features are first released here, before we consider them to be sufficiently reliable for the production wallet. It serves as a public feature-testing platform for the Trezor community, providing power users with quick access to new features. Even though it is mainly for testing purposes, this wallet is safe to use as in all cases, your private keys are protected by Trezor device.
Old Wallet (old-wallet.trezor.io)
It is an older version of the interface intended for backwards compatibility when a new version is released to Trezor Wallet (wallet.trezor.io) (production) web wallet interface. It is useful when some significant changes are applied. In other words, the previous Trezor Wallet ends here when it is replaced by the newer version.
Wallets can be used interchangeably, as they are just the interface for your Trezor device.
Our products are running under the LGPL 3.0 licence.
Please use this link for more details regarding the licence.
For more information related to legal matters, you can use the general overview on our e-shop.
First of all, we certainly do not plan to stop our business, but even if something unexpected happens, you can use Trezor with a variety of compatible third-party services. Some of these services can be used for the recovery process, letting you access your funds directly in the respective wallet.
Here is the complete list.
Moreover, since our code is open-source, developers from around the world can maintain it and add new functionalities.
Advanced users can run their own local instance of Trezor Wallet interface in combination with the local blockbook. More details can be found here.
