I have:
Flex
Ktag genuine
VCDS Genuine
Many J2534 devices including cardaq 3
VVDI2
I've supported many hobbyist programmers and purchased their softwares.
MANY clone tools
I can eeprom with the best of them.
One thing I absolutely cannot pin down is how to flash an SGO file to return an ECU back to stock. I've heard Autotuner does it but that's quite the coin to just goto factory. I could flash a known factory file but that isn't always easy to obtain. How on gods green earth can I flash an SGO. I'm having a hell of a time with Odis-E 14.1 and my cardaq. I'm having issues with cloned VCP6(Vag Can Pro 6) and i've bricked a UDS unit already just messing around. Does anyone have an absolute fool proof way to always be able to return to stock quickly and easily for less than 5k and no crazy annual subscriptions?? I don't have a lot of faith getting Odis or VCP to work reliable considering i've spent two days on odis and can't get past this stupid error.

Any help would be greatly appreciated.

Well there aren't many tools that will actually do it. Yes, back to stock is only for flash, that's the goal. UDS/FRF whatever. Point is I'm looking for a suggestion. The problem i'm talking about is finding a tool that will reliably flash .sgo/.frf that doesn't cost 5k+.

Seems you talking about VAG - WinOLS can convert. For single ask - just share file.

Does it need to converted to bin or will it just flash SGO directly? Any experience with what does and doesn't work would be greatly appreciated. Does it skip flashing the immo or just paste right over top of all of it?
