If you are experiencing issues when trying to update Jade's firmware, it may help to try the following troubleshooting steps. Visit Settings on Jade and select Bluetooth, then choose to Reset the Pairing. If updating over Bluetooth, turn off "auto-lock" or make sure your device's screen does not go to sleep, as this may interrupt the connection. Download Blockstream Green on your desktop and update the firmware using a USB connection. Update to the latest version of Green if you are not already using it. Perform a factory reset and attempt the firmware update again. Make sure your recovery phrase is backed up before doing this.
