Failed to Update VVDI Mini OBD Tool Firmware 2.0.1 Solution

 Problem:

I have failed to update the Xhorse VVDI Mini OBD Tool firmware from 1.0.5 to 2.0.1. I have no luck in the App or via the Upgrade kit. Is there any solution?

Solution:

If failed to update mini obd tool firmware from 1.5.0 to V2.0.1, replace battery of mini obd tool.

Replace a new battery (CR2032), update firmware and sync device again.
