Trezor One-users: Once updated to latest version

(v. 1.10.0 & Trezor Suite v. 21.5.1) , do NOT install the #Bitcoin only firmware on Trezor One:

"Unknown Bootloader detected". If you are lucky, it will ask you for your seed after several attempts.

(Hope it is a fixable bug).

is it possible to fix this issue with a "userfriendly" command line instruction?

I dont have the seed with me...
