I have a Minipro TL866A,, after I did the software and firmware update, it stopped working . It's not able to read or write any devices.
When I try the "Self Test" in the tools menu, the test GND TEST 07 fails.
I would like to know if anyone has had a similar problem and if there is any way to repair this type of failure.
I thank everyone in advance.
Greetings,
Edoardo
