Two devices sold as Safe 3 can require different binaries. Read internal_model
with trezorctl get-features while the official firmware or bootloader is
running. After installing feuristic, use Settings → Hardware / version.
Never choose a binary based on casing color or the retail product name alone. The installer must report the exact model before uploading.
What changes when you install it?¶
The Safe 3 becomes a security key and smart card. feuristic does not implement Bitcoin wallets, signing cryptocurrency transactions, wallet-seed recovery or migration from Trezor Suite. The official bootloader remains the recovery path.
See installation for storage erasure, bootloader unlock and the permanent loss of original manufacturer attestation.
