10 mins probably were not enough to re-check all the checksums.
You can fix the binary with me7sum and flash it afterwards, should be fine.
Yes you are right the car didn't start today on the modified bin from the tuner. Checked the file again with me7check and it found 1 error. As suggested i used me7sum to fix it and it now shows no faults on me7check!
When i have time i will flash the file on the ECU and let you know how it goes!
Thanks all!
