Hi

 

Some years ago I swapped 5E0035871D unit with more advanced one. Before selling that car I tried to put old one back but CP protection kicked in. So I sold with new unit in. 

Now cleaned my room found that old unit (5E0035871D) CP is active. Thinking maybe it is nice project to try to remove it. I have some skills with reading/writing eeprom. I can do soldering. 

I know I can walk with that unit to dealer and ask to use ODIS to remove CP but that is not so interesting to hack it by my own. I know if component is not under CP then you can swap eeproms and get new unit to work. But is it possible to clean CP using hex editor? For that information about memory area where CP living in eeprom is needed and decoding information also. 

So is it doable without owning very-very special tools and skills?

What you are asking for is not how component protection works.

 

CP is there to lock the module to the vehicle specifically. You cant just take a module to someone with odis and ask them to remove it, it needs to be in a vehicle and assigned to that vehicle, if it was taken and placed in another vehicle then it will be locked. 

 

Now regarding reading and writing eeproms, there are people out there with much much bigger budgets and vested interests in cracking CP whether for theft or other reasons and they havent managed it easily (very few can do it).

Regarding removal of CP for a 5F module, this can be done with the MIBtoolbox but it is a superficial removal and simply allows full functionality, fault codes relating to CP still remain.  

Can you apply mibtoolbox without as card but with usb drive input?
