Hi, i have btc only trezor 5 orange color, i want to change firmware to unviersal using custom firmware, will i have fido2 after and will i keep my bitcoin after doing so?
Hi @Majkelek,
I can confirm that you can change the firmware to Universal version via the installation of custom firmware.
You will have the option to use FIDO2 feature with the Universal firmware. Keep in mind that your Trezor device will be wiped after the change to the Universal firmware, which means you need to recover your original wallet with the recovery process. Then you will see your BTC. Information on how to perform the recovery process with Trezor Safe 5 can be found at Recovery process for the Trezor Safe 3.
will i be able to restore original firmware later if i change my mind, perform some sort of factory reset?
Yes, if you later decide that you want to switch back to the BTC-only firmware, you can do it without issues. However, please keep in mind that the BTC-only firmware does not support FIDO2.
