Tried tuning an LB7 a couple days ago and hit a wall. Says boot loader rejected because the controller is locked with a custom key. Tried the $FFFF key and no bueno. Tried all various options of high speed/low speed flashing and v7/v8 and nothing could read the tune out. Also my v2 doesn't read the vehicle vin properly. I Got a string of random character. Do I tell him to get a dealer reflash or is there another trick I can try to get in there?
it has an aftermarket radio, but we pulled almost all accessory fuses one by one and still nothing.
I'm failrly new to using the V2. all of my experience so far has been using an autocal for the interface. If I'm doing something stupid please point it out. I've searched on google for a while now and haven't found anything that really confirms what's going on.
Thanks in advance
