Note: The following feature is only available with Jade Plus.
Jade Plus lets you connect external accessories to unlock brand new functionality. When you connect JadeLink to Jade Plus, the device can read available files stored on the JadeLink and perform firmware updates.
Updating Jade Plus in this air-gapped fashion not only allows for faster firmware upgrades but also improves security by limiting remote attack vectors.
Warning: Only follow this procedure when using a .bin and .hash file downloaded directly from the official Jade firmware upgrade page.
Air-gapped Firmware Upgrade Process
You can follow this process with most FAT32-formatted USB storage devices or SD card readers, however we recommend using JadeLink to avoid potential compatibility issues or security threats.
1.
Navigate to the firmware binary download page and select your desired version, then click Download Binary. Open your Downloads folder, locate the .zip file, and unzip to retrieve the firmware .bin and .hash files.
2.
Plug JadeLink into your computer or mobile device and copy the firmware .bin and .hash files directly to it. Eject JadeLink and connect it to your Jade Plus.
Note: In order to be recognized by Jade Plus, the file names need to be the same as when they were downloaded and cannot be duplicates with a trailing (1) or (2), for example.
3.
Navigate to USB Storage on Jade Plus by selecting Options on the main menu. If your Jade Plus is initialized, you will first need to unlock it via PIN with QR, USB, or Bluetooth. The USB Storage option will be displayed when your Jade Plus is unlocked in an Active state.
4.
Select Firmware Upgrade and choose your desired firmware binary, downloaded from the Jade firmware upgrade page.
5.
Review the firmware details, then click the checkmark to confirm and begin the upgrade. Your Jade Plus will reboot after the process is complete.
