Trezor firmware update for a Bitcoin only wallet

The community has spoken, and once again, we deliver! We are thrilled to announce that the stable version of our new Bitcoin-only firmware is now available to download for both Trezor One and Trezor Model T. After the initial testing of the Bitcoin-only firmware done by our beta testers, we’re proud to now release this firmware to our stable version. From now on, we will be producing four different versions of firmware — regular (full altcoin support + U2F/WebAuthn) and Bitcoin-only, for both Trezor One and Model T. By default all Trezor devices come with a regular firmware and you can optionally update to the Bitcoin-only firmware. We have created a customized version of both our firmware and Wallet designed for everyone who supports the idea of Bitcoin. Every Bitcoin maximalist can now enjoy the Wallet interface with nothing else but Bitcoin. How to install Bitcoin-only firmware Before you jump straight into installation, we recommend testing your recovery seed in a dry-run recovery. It’s also essential to note that after installing Bitcoin-only firmware, all your other coins will not be visible in the Wallet interface — but don’t worry! The private keys to your altcoins remain protected within your Trezor. The regular Trezor firmware is required to access your altcoins. You can swap between the regular firmware and Bitcoin-only firmware as many times as you like. There are two ways of installing the Bitcoin-only firmware. You can use either Trezor Wallet or trezorctl(advanced users). This process is also described on Trezor Wiki. You will need: Trezor Model T running version 2.1.0 or newer, or Trezor One Access to Trezor Wallet or trezorctl The correct firmware installation file for your device — Trezor One or Trezor Model T Installation process using Trezor Wallet: Visit https://wallet.trezor.io/ and connect your Trezor.
