First problem. The V2 needs to be plugged in, in order to upgrade the OS. then once that is done you no longer need the V2 plugged in to make modifications to the .tun file you created.
When full flashing you don't need to do anything to the onstar or pull fuses that was a LLY and LB7 thing. '06 and newer trucks use a dedicated GMLAN and not the Class2 databus to flash. The only things on the GMLAN is the TCM and ECM, nothing to worry about.
It would also probably be a good idea to familiarize your self with the PDF document that is provided with the beta software as it is the upgrading tutorial.

ok ill try plugging the V2 in and let u know but for full flashing on the LBZ i just need to turn off my radio and stuff like that and do a full flash and no harm done??? correct? ill get back with u in a min on the update thing cuz i updated everything and repulled the tune from my truck and still no luck on custom OS but ill try again .. thanks
-
ok plugged V2 into my computer and still no luck on custom os showing up?? i have updated the V2 and scan and tune and tune and explorer. i dont know what i did wrong? should i maybe try to reinstall the update?? or restart my computer maybe?? thanks
-
The tune file that you save from you truck is all you need. the V2 needs to be plugged in before you open the .tun file. then it will work.
No you DO NOT have to do anything special to flash the truck. EFI flashes the ECM on the GMLAN where the only things listening are the TCM and ECM. no other precautions are need to flash.

ok thanks i feel comfortable reflashing now but still no luck with custom OS idk what im doing wrong do i need to plug the V2 into the truck also and the computer for it to show up?? this is exactly what i did.. i updated everything twice now restarted my compouter and pulled the tune out of my truck now im in the housewith the V2 plugged into my computer and still no luck whatsoever i have to be missing something .. do i need to do a full reflash of my stock tune?? then try it i dont know man i really appreciate you hleping me alot thank you
-
have you saved the tune file to the computer? this is something that you have to do. download tune from truck>>>save the file to the computer>>>close EFI tune window>>>plug V2 in computer>>>>open saved tune file>>>>then upgrade OS. if that doesn't work you do not have the .calz files in the correct place.
-
ok now were getting somewhere... i done all that but the .calz files?? where are they and were do they need to be at thanks so much

look at "program files/efilive/7.5/calibrations/E35 and check to see if you have a folder called "custom" and within that folder do you have a bunch of files in it? and in the E35 folder check the date of creation on the OS that you have.

i cant even find the calibration folder?? i found the bins folder with custom os in it but theres no E35. i done a search for the folder and still cant find it i guess im just screwed
