Problem:
I got the error 86 on my xhorse dolphin xp005 key cutter last month. I have it checked with my dealer and got the main board replaced. Now it has a new error 02233. What should I do?
Solution:
Delete the original Xhorse app on your phone.
Or download this apk on another mobile phone. Do not update apk after installation.

Open this app, bind device, go to Device Information->Parameter List
There you can close the error code.
