Im very new to EFI Live and tried to flash a tune to my LBZ tonight with some very bad results. I received a $0101 code and the V2 cannot establish a connection with the ECM. The tune I used was just a small daily driver tune someone submitted to dieselplace.com's tuning library, I figured it would be something to learn the process with, I changed the vin and proceeded to flash the ecm. I used the V8 software and that was when I received the error. Now if you try to validate a connection trying to use V7.5 it won't show any connection at all. Firmware and boot block is all up to date and like I said I'm new to this so please walk me through how y'all would evaluate the situation.

The truck previously had an HP tune on it and I've heard this causing some issues but hopefully that isn't what is causing this. I do have access to the HP module to reflash the tune with it but I doubt it will be able to make a connection either.
