Downgrade firmware Trezor Safe 5

Before you start, please note that we do not recommend downgrading your firmware, unless there is a strong reason for it.

Installing custom firmware on your Trezor device could erase its memory and may make it unusable. Never use this process unless you really know what you are doing!
