Some users have recently encountered an upgrade prompt in MetaMask, and after selecting the upgrade, the hardware failure error appears as shown above.

Please take a look at the following options:

1. Unplug the data cable and turn off the device first

2. Then press and hold the power on and down keys at the same time to enter bootloader mode

3. Open the OneKey upgrade page:  https://firmware.onekey.so/ 

4. Connect the OneKey hardware wallet for upgrade

Note: If the hardware wallet crashes due to a mis-installed firmware, you must wait until the hardware wallet is fully charged and shut down before connecting to the computer to re-upgrade the firmware.
