Customer problem:

When I used VVDI Key Tool Plus to read eeprom, it prompted ‘Self-test error: FPGA certification error’. It just happened occasionally. Sometimes I restarted the device 4-5times and it used normally, but sometimes it still stopped working.

Xhorsetool.com engineer replied:

There is something wrong with the PCB. You’d better send it back to repair.

Here are the steps to remove the PCB.

  • On the edge of the device: 8 screws
