I was on v1 and updated to v2, and that's where is believe I picked up the corrupted firmware. AND here's the kicker, you have to downgrade before you can upgrade again or it just looks for missing files as an upgrade. I just haven't looked into what the protocol is to downgrade. I know you can just load the firmware to the SD card, but that doesn't do anything with the ECU. Mine is stuck in the sync mode, which I believe is the ECU downgrading. The ECU has a v2 tune in it, so I don't know if that is causing some problems..... I just don't know right now, and work is freaking brutal, so I have zero extra time..........UUUGGGGHHHHH!!!!!
