I have a little tuning experience, and have flashed tunes on ME7.1 cars just fine but today I flashed an ME7.1.1 allroad with a bin (CS checked) that I've ran no problem on an S4. Now the car doesn't start and i can't communicate with it via Nef or Vagcom. How should I fix this?

Thanks for the reply.
Is cross-flashing ever possible? I didn't mean to flash it onto a ME7.1.1 car, just something I overlooked this time.
Will reflashing the original tune in boot mode with a tool like Galletto or MPPS likely fix it?
I'm working on getting Galletto set up with my genuine Ross-tech cable, I've edited the serial and have a bench harness already made, I am just having some trouble with the drivers it seems, I'm getting the "Boot Mode Not Active" problem even after grounding pin 24 for various amounts of time.

I'll buy whatever cable I have to, but I'm right here with my Hex-Can for now and am close to getting it working but I keep getting the boot mode inactive warning on Galletto, I installed the Rosstech VCP drivers and have even tried to do so on a computer that has never had VCDS installed on it. Still getting boot mode warning. I'm pretty sure this is the setup that nyet is using.

Thank you for your reply, I have been trying to put the ECU in boot mode. I have Galletto open, I have my power supply connected to my bench harness that has an extra ground wire with 1 kohm resistor and an on-off switch for the ignition on signal. I click ECU Data on Galletto, it prompts me to turn the power on while grounding the pin, I ground the pin, turn the switch on then pull the ground off the pin a few seconds later. Galletto tells me:
 DATA READING
Start data reading...BOOT MODE INACTIVE

While researching this issue most are saying that this points to a driver issue and not that the ECU itself is not entering boot mode but you might be right at this point, I've pretty much covered everything driver-wise.

Trickier how? I did try a Me7.1 and I was able to read and then flash it in boot mode with my Galletto setup.
Is ME7.1.1 able to be done this same way or is the procedure to enter boot slightly different?
I have tried powering on all at once (no simulated ignition), the resistor, and grounding the pin for exactly 3 seconds like some say you must do.
