Hi,
Reading a ME 7.5 (A3 180 APP engine, checksum disabled ecu, tuned file), the msg above always comes up after 50% of reading.
After 3 times, it says "flash checksum still does not match after 3 attempts, giving up and skiping".
Does it means that the content was disregarded when skipped or just not "validated" ? From 50% on, every block read goes through the 3 attempts.
Tried:
29F800/29F800BB/29F800/BT layouts - stills the same
All possible baud rates - stills the same

Should I let it go all the way til the end and I would be ok with that pulled out ".bin" ?
Tks

1. You didn't post your ecu number.
2. You are using an old beta of nefmoto, not the current release.

Fix that.

ECU 06A906023S

I was in fact using a older nefmoto version. I didn't realize that the link at Wiki was not calling for the latest release.

Downloaded 1.9.3.2. and will try again.
