I’m trying to do upgrade from 1.5.3 to 1.5.7 on dolphin xp005 and it’s stuck in bios and won’t update. The error code: 7:03:00:00:00.
The suggestion of Xhorsetool.com engineer:
Please open Xhorse update kit software
Click Repair>> fix internal error 1&2 on the top right of the menu
After fix successfully, click ‘Upgrade’ to update the firmware again.
