Bootmode and recover? FYI I never had an issue with ME7sum and I've flashed well over 50 or even 100 times by now, even with custom code in the bumfuck nowhere. But also, your posts make no sense, can you connect with VCDS or not? Can you connect on the bench etc?

But also, your posts make no sense, can you connect with VCDS or not? Can you connect on the bench etc? My post makeks sense .... Becuse i read and write with nefmoto Flasher, after Flashing starting the Car it works perfekt after amount of time ( car lock) Car wont start anymore. Then i try to write Orifile with nefmoto flasher same issue car wont start ... So then i try to read via Nefmoto flasher the dtc´s but it cant connect. Then i try to read the ecu with VCDS and the ecu is responding with the Erorr - > Steuergerät defekt - Checksumm Erorr I fixed it now with KTAG flash. And all works fine.

Yes ... im sorry thats what i forgot... but on a 018CH Box it works without problems - and that was a virgin ECU Title: Re: Checksumm error after Flashing Post by: IamwhoIam on November 28, 2022, 03:01:40 PM i used winols Checksumm plugin ( Original ) - and after the second flash i tried nefmoto checksumm tool both dont work .... what did you do? thanks a lot Which version winOLS? Title: Re: Checksumm error after Flashing Post by: Blazius on November 28, 2022, 04:07:02 PM Yes ... im sorry thats what i forgot... but on a 018CH Box it works without problems - and that was a virgin ECU 018CH is an RSA'less software, with RSA you have to be careful with the placing of certain variables in certain locations if you are using the script but apparently ME7Sum should still work, specially now(nyet?). Check your file but again give Me7sum a go. Recover first obviously if you havent already done it.

That is granted yes.Title: Re: Checksumm error after Flashing Post by: xXxCryxXx on November 29, 2022, 12:17:24 AM Which version winOLS? Winols 5 version 5.30.00 Title: Re: Checksumm error after Flashing Post by: xXxCryxXx on November 29, 2022, 12:20:42 AM ME7Sum cannot fix *literal* problems introduced by bad ASM doing bad things to things in RAM. Yes thats what i think but do you know why the tool writes the Original File on ECU but the car wont start? The problem was solved with KessV3 Flash on bench - no boot flash - maybe you know why but im not ^^ Title: Re: Checksumm error after Flashing Post by: nyet on November 29, 2022, 12:22:59 AM Yes thats what i think but do you know why the tool writes the Original File on ECU but the car wont start?
