So I've been trying to flash my 2016 Duramax, I try doing a full flash and select ok, says please wait>ignition off now> then starts the 40 second count down. So I go ahead and try just a cal flash and sure enough it lets me license the ECU and flashes the truck. But now truck wont start, is there any reason why it wont let me do a full flash? What am I doing wrong?
Did you try the full flash AFTER it licensed or only before?
That was the proper process for licensing. After its licensed it should full flash

Yes I tried to full flash it after I licensed and cal flashed the ecu. Still goes straight to wanting to do a count down. I also tried flashing it using my laptop and this is what I get.
What's the Boot Block number of your ECM? You can find that out using the option: [F4: OBD]->[Retrieve All Information].
Currently E86B full-flashing only supports boot block: 12657305
If your ECM's boot block number is different to that, then we'll need to update the software to support the new boot block.

I did two 2016 Duramax last week and the first one I did failed the cal flash and would not start and did the count down on the full flash. I cal flashed the stock file and the truck started again and then cal flashed the new file and all went well. The second one cal flashed correctly using the same file for both. I didn't check what boot block number was though. One other thing I noticed on both trucks was when using the scanner the IPC and turn signals would freeze up which tells me something on the can bus wasn't happy. Both truck returned back to customer now.
Thanks

Should be no reason why you would need to full flash a 2016 LML, the option is there because we can do it but it doesn't really achieve anything. Don't feel it is necessary to do this to recover from a failed cal flash, if a cal flash fails it only takes a cal flash to recover it.
Thanks for the feedback Mike.
