Problem:

Failed to update xhorse vvdi mini key tool firmware via app and via upgrade kit on PC.

When update firmware via app, it reported error “Erase the internal chip 1 fail”.

Here is the VVDISHOP engineer solution:

1. Turn off device.
2. There is a small hole on the back of the device case. There is a button inside, press the button with a toothpick, then hold the power button.

3. Turn on device, then try to update firmware again, it should be fine.
