Opcom v6 come from china with fake & scratched MCU PIC18F458, so you can not see label on the chip.
Also this chip is not programmable, when you try to update firmware you will erase MCU. Only way is buy original MCU , change it on opcom PCB and reprogram again (or buy new chinese opcom)

can the security code be found with the v6 1.45 firmware for corsa-c?

I don't know. I don't have Corsa C.

I purchased on aliexpress. I asked whether he has Op-com with the real PIC. Here is what Chinese wrote:
"Dear friend, i think you make a misunderstand
the software version is V1.45 , the hardware is 2010
Dear, pls don't use other software on our product
if we have newest version, will send you
thanks"

Few minutes ago i have contacted the seller in my country and he found a 2007-12-10 (something like that) in the darker deeper place in his depot. Also there is one 2010 but i prefer 2007.

Will ship today and i can get it tomorrow, first thing to do will be disassembling the opcom and post the photos here.

Itwas something pricy than ebay but, i think it will have more lifetime than ebay's. (which is 30mins )

Finally I found the offer with a detailed description on aliexpress:

Mate when you'll recive the tool from aliexpress.com please check if you have luck that the tool that you will recive it has the L9637D k-line transciver.
Because as you can see in the pics from aliexpress.com supplier this chip is missing
Anyway this it has a small price so you can buy it and solder it there. Otherwise your controlers on k-line cannot ge detected.
Good luck

For now, I'm not going to buy that.

[mattydr67]

Anyway my post it is then for the one who will buy ( from that seller ) that tool has k-line tranciver L9637D ( Si9241 ) missing and if they need the tool to works in k-lines cars they need to solder one chip there.
Good luck

New opcom arrived and I think I can downgrade it to 1.39?

(little scary this time)

[domelec]

Yes that is opcom hardware v5 with real pic

[zottaba]

Downgraded to 1.39 (in the bricked opcom serial# changed after firmware changed, doesnt happened in this one)

hope it works without problem
