So, I just got my Maxx HD from verizon..... Tried to root it and failed.... Researched and found this thread.
1. The all in one setup is awesome. I used to dev and helped create the LG Ally root back when I had it... So this makes me happy.
2. This method worked for a phone that just arrived to me from verizon with the update installed by them, so I had no control over waiting to update.
3. I would like to thank all of those involved and hope to one day be able to unlock the bootloader of my Maxx HD, but I have stopped digging for bugs also, so I know its unlikely.
Thanks again and yes, it worked, yes all of my data is safe and still on my phone!!!!
