VW Magneti Marelli 7GV ecu

Hi,

I have a problem with a Magneti Marelli 7GV ecu frpm a vw Polo CLP engine, I have done a read and did a write with a bought file.
The vehicle didn't want to start afterwards. It was all done with Kess, Alientech tried to help but we couldn't fix the problem.
They do believe that the file was the problem causing an error in the ecu to prevent a recovery.

Can someone help me to recover this ecu, what tool can do the job?

Had this with a 7GV and a 2018 Polo. My genuine Kess doesnt have a recovery option for that ECU (option available but never worked) , used a clone kess and recovery worked perfectly with ori read from the car. Done loads (over 60) with Genuine kess but recovery, ive always resorted to clone kess, genuine recovery for 7GV never worked as intended for that ECU

I still have the ecu and I do have the Kess clone so will test it. thank you for your advice
