You can update the software by follow steps:
1 Download the latest updates package from Onyx website:
www.onyx-international.com
2 Save the updates package in a SD card.
3 Make sure the updates package is located at the root directory of the SD card. The name should be ‘onyx_update.upd’.
4 Insert the SD card into Boox.
5 Restart Boox, press and hold the OK button. NOTE, the OK button should be pressed before the device restarts. Hold it until you see the message ‘Software update request detected, checking updates…’.
6 Boox updates itself automatically. It restarts after update finishes.
Reminder: Make sure Boox has enough power to finish the software update (at least 2 grids displayed).
