I have updated the 3rd post of my VIA repair/reprogramming thread with Ets scripts which wil automate the entire process. Talk/Text/3G. MMS will have to be set manually. If you get stuck you can always PM me @ XDA.
As for the link - http://forum.xda-developers.com/showpost.php?p=27080787&postcount=3
If you are using a Verizon Gnex be sure to read the entire first post of the thread as well as the entire thread. The Sprint version is much easier to work with. Verizon is possible.. so don't worry.
Just read that post for directions. Install Ets, drivers... get connected.
Scroll to last script in the above link. Load up script file in the Ets Script Utility(Ets > Utilities > Script Utility) and edit the 6 or so custom values which the script asks for(you'll see when you look at it).
** "Hardest" requirement is getting nv item 1192(aka Profile 0 AAA Password hex) and the Profile 1 6-character AAA text password from MIP Profile 1.**
- After you fill out correct values and you're 127% sure your phone is connected to Ets... PRESS THE PLAY BUTTON in the Ets Script Utility and watch your phone get programmed and reboot after it's finished. Done. 3G takes about 1 min to come on after a reboot. Time to program MMS.
