I had but no answer at moment maybe he havent got OLS800 (as iam also dont get) :/ and would need car tomorrow.
Because its daily one.
If you can do give me a pm.

Kess told it can correct but if i choose file it tell me cant be written because checksum arent okay.
Also if I check file there are some curious things. No ISN can be initalised, no vin can be initialised.

Thanks in advanced.

Got the correct OLS CHKS and done :D.
But also Ktag, Kess can fix chks... you need more Voltage... last time tested with only 12.8V... later 13.8V (works).
