If you ignored the warning to "NOT REMOVE POWER TO THE ECM IF THE FULL FLASH FAILS" and to keep trying to complete the flash your ecm is bricked.
Three warnings come up with the software, with a BBX flash it does not come up.
The LB7 ecm has the bootloader wiped and recoded during a full flash, this is the only duramax controller that has to be programmed this way, all others have a separate boot loader that does not get rewritten.
If you powered it down without completing a full flash it is a brick.
Send it to Socal Diesel for a flash chip replacement and off line programming, you will need a new VIN license as the SN# will not match anymore.
Call Lorenzo or Guy on Monday.

Tony when you say do not remove power what does that mean? Turn the key off and she's done? Sounds like it's a brick then.
I did not get the instructions to update firm ware and boot locker until after the first flash. Truck seems completely locked and will not communicate.
I have the EXSACT same issue and had to replace the ecm,the os in the tune didn't match as well as the vin,maybee that was the issue but never did figure out what happened,have you tried to get your license replaced and how did/do you go about it?Im a tech dummie but would like to get it replaced as well as you prob will.Hope you get it fixed ok!
I haven't asked about the license but you would think efi would allow another in a situation like this. Especially since it is software related.
I was told we can get a licence back if we provide proof of failure,I don't have a clue how to retrieve or send the info to them,Trying tofigure it out cuz a fresh built trans tune is in order instead of the ppe im using now,If I figure it out il let you know how I did it and hopefully you can get your vin back.have you got the truck running yet?
I'll send them a video haha. I can't read or flash even with fuses pulled that I could get away with pulling. I'll let you know how it goes. Ridiculous all this for a tune.
No kiddin,Was told by efi live the lb7 ecm is flakey at best so we prob didn't do anything wrong,just a shit happens kind of thing!
Were you guys able to get a license back after this happened? My ECM was toast after i tried a full flash last week also.
Never figured out how to get a replacement license but still have my bricked ecm on top of my fridge so maybe there is still hope!How did yours go down?
I haven't tried to get a replacement license yet either. I tried to flash some new tunes on it, but it zipped right through the programming process and told me to turn the key off. (i remember thinking, wow....that didn't take long) Then i got a no start and $0101.
