Problem:
I tried to update xhorse condor xc-mini plus key cutting machine from PC via xhorse upgrade kit, but it failed to update, error 400. Any solution?
Solution:
Change laptop or cable, update several times again.
If all not working, you may need to replace the mainboard.
If your device is under warranty, contact your dealer to send it back to repair.
If out of warranty, you need to purchase a new mainboard.
