Pretty sure its connected that hole has a via like I said which is small metal ring pressed in the hole and connects to other side its just been covered by greencoat if you check I'm sure its in ground plane not separate pad but as you say check with voltmeter to be sure.

Enabled let me and domelec know the results

Will do. I have 2 of these, that I will flash to 8.21.




My original one (from 2 years ago), I had to lift the pin, and I was a bit timid about it, as I never did something that small before successfully. But it went well.

I flashed 2 of these Carprogs without lifting the pin. I just soldered thin wire directly to the hole. It erased correctly, and wrote new flash just fine.

On newer style Carprog, no need to lift pin, no need to cut tract.

Hy
How you flash it ?
Using jtag or other methods?

Mine is dead so i wont try to fix it

Thnx

Hello you can use a JTAG wiggler or Jlink all instructions are here on this thread somewhere you have to erase MCU using the via/through hole connected to pin55 then program
If you get stuck let me know and I will help.
