Hi, my problem occurred about 3 years after I connected Trezor One to Trezor Suite. It immediately showed me that “Device detected in incorrect state” and suggested “Updating firmware will delete your wallet backup. Verify your backup now to ensure you can recover your assets = Check wallet backup”. At this step, the problem occurred - “Wallet backup check failed — Device recovery failed: ui-device_firmware_old”.
How should I proceed?
Do I have install filmware (Current version 1.6.3, Latest version 1.12.1)?
Can I lose my wallet permanently?
I have my seed stored safely on paper!
If you are 100% sure that your seed phrase is recorded correctly, then you can directly upgrade the firmware.
