	A4 B6 1.8t BEX - Not starting after flash « on: November 16, 2019, 05:21:14 AM »

Hi all, new member here! I have been thoroughly enjoying the forum and all info! I'm learning a lot.

I have recently used nefmoto flasher to read my ecu files and have obtained the file successfully, the car now won't start. I have tried to reflash the file back (completed successfully) which didn't help. Checksums look okay. I have had the battery connected during read and flash to ensure constant voltage. Both nefmoto & vcds still connect so guessing ecu is okay?

Attaching the bin

All help is greatly appreciated.

ANY CODES? like programming not complete? if so try reading the file you wrote back off the car and it should end the programming session proper. also one of the stickies covers this too you can find the string of bits and edit it so youll never get the error again

Just made the hex correction as advised in the sticky, i'm having a problem with me7correction not validating i get error that file can't be found (I have bin in same folder as exe). I have searched forums and can't understand why?

I have attached the bin file if anybody could do checksums for me please? Or advise on the me7correction file not found

Many thanks

Corrected the hex (as per the topic above) and used me7sum along with resetting stored checksums on startup and all works now. Thanks!
