Hi,
I have and ecu toyota avensis.
275036 7341 with 76f0040gd. I want to immo off.
I read via ktag clone but cannot write back mpc. Ori will write, but mpc and eeprom will not. I tried many things, using xp, adding -ve, boosted voltage and Amp.
When wring mpc I get to select original file. Then I get 'operation not allowed'

Can we immo off by eeprom? I see many on the board (example L56R)
Or can I read and write with vvdi prog?

I have iprog clone
ktag Clone
Orange 5 clone
Vvdi prog
