Corrupt RCC and component protection

[SpecFroce]

Hi everyone.

I have a MIB 2.5 unit that was retrofitted to my MK7. Coding and adaptations went fine and everything worked until I decided to update the unit on my own. I managed to corrupt the RCC and the flash partition and I sent my unit to the UK for recovery.
The procedure was successful except for one thing.
The component protection cannot be removed due to an CRC fault according to ODIS.

I have no prior backup and while the unit can be hacked I want to unlock the component protection legally if possible.
The EEPROM is from what I have been told corrupt.

Can the EEPROM be reprogrammed or cloned from a similar unit or is it a lost case ?

The part number changed from 5NA035043B to the same number but ending with D. Any insight or advice would be greatly appreciated. My hope is that the EEPROM can be cloned and restored but I have not the right equipment or experience to do it.

Attached to this post is a screenshot from official ODIS and a paper copy of the unit before it was updated.

You can consider to update the FW in your unit, but that way you loose all your unlocked features.

It’s already updated.

It's a EU unit. Can you make screenshot from HW/SW version screen?

Yes, you have the latest firmware. On the picture from paper there was a older version. CRC errors can sometimes be solved by upgrading to newer version firmware. So i'm out of options.
