Problem:
I am having an issue with the xhorse mini key tool. I was updating it (firmware) via upgrade kit and the battery died. Now I keep getting fails trying to complete update and tool is stuck on ‘USB —PC’. It says SAFE1 also when I turn it on.
Solution:
Firmware upgrade should be done via Upgrade kit.
If key tool battery is low or the internet is unstable, you will fail to update firmware.
Charge keytool and change network, try several times.
If all failed, there is something wrong with the mini key tool. Send back to your dealer for repair.
