Just so you guys are aware, I tried to make a nandroid backup of my Verizon GN2 once I saw that Rom Manager had been updated to show my VZW version and I was able to use it to flash recovery (as I have done with my Droid 1, Droid-X, Bionic, AND Galaxy S3 with not many major problems over the years, except for on the Bionic). But as soon as I chose for RM to "Backup my current Rom" my screen flashed and instantly showed me a black screen with a yellow triangle on it saying that I was running an unapproved version of software and that I had to turn my phone off and take it into a Verizon location!
Of course I tried to reboot, boot into recovery, pull the battery, etc., etc,...and NOTHING WORKED. I eventually had to reflash the stock image in Odin just to get the phone back up and running. This really pissed me off since everything was perfect, which was why I wanted to make a backup of the complete device in that state (just in case something happened, and here is the backup software CAUSING the very problem to happen, and BEFORE a complete backup could be made to restore from.
Thank goodness for Titianium Backup or it would have taken even longer to restore things. Just watch out all and let me know if any of you were able to make a "successful" nandroid backup within Rom Manager of a Verizon GN2 and Restored it to prove that it worked, and if so, did you have to do anything different? I heard that the Galaxy Note 2 toolkit floating around can make backups, but I don't really trust that either, plus it has to be done via PC instead of with the actual phone.
