RE: OP-COM v6 with "fake MCU" REPAIR
I said that its similar.
This tool is need a Ft232RL
The Ft232RQ is similar and its has same functions
As I said the most important is the PIC MCU
Good luck

Finally, i managed to get 2 more pictures of the board. These look like this:

Is it worth to buy it (can i up-/downgrade the firmware), or better choose this second one?:

What is your opinion? Please guide me to the right device.


Kind regards,
Astrid

Hi
Well if you want my opinion I will choose the last one
The one with FT232RQ its seems that its using a fake MCU ( in my opinion )
The last one with FT232RL it seems that its using the right MCU not fake one
But if you wanna my opinion chose one of this
Good luck

I have OPCOM v6, initially on 1.59, flashed by mistake to 1.45 and now it doesn't connect to car. It refuses flashing FW.

RE: OP-COM v6 with "fake MCU" REPAIR
You need to replace the MCU and you have to do some changes in PCB
There is no way to flash this MCU ( as we call it fake ) if you don't have its dump
Good luck

Try use with software 120309a is much better work than mixed software 120309a+131223d

Quality tool as the beautiful woman...

RE: OP-COM v6 with "fake MCU" REPAIR
Do you mean if it can modified to use a original Pic18F458? - Yes ( as you can see the title if the thread )
Bricked could mean many things. As Can Bus or/K-line defective
Or even Pic not flashed. But in your case you have to replace it
Good luck
