A customer was trying to combine xhorse dolphin xp005l key cutting machine with xhorse app, but failed.
Xhorse app showed “Params error: nation-code” and xp005l screen said “use App to scan QR code to combine device.”
- First login Xhorse app, then scan QR code to combine device
- If aleady enter account, log out and login again.
Hope it helps.
