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?
Br,
