I have a rooted Galaxy Nexus that I'm considering sending to Assurion for replacement due to a cracked screen. Couple things I need to know. First off...I rooted it a few months ago (I'm no expert at these things...I just followed directions on this site). I didn't install a custom ROM, I just basically wanted to root it so I could customize my desktop and what not. Secondly....there was a point where Verizon wanted to push JB onto it but I didn't want it to mess things up for me so I found a way (with help from this site) to prevent the update. Those two things being said....what do I need to do to prepare this phone for returning it to Assurion? I want it to be completely wiped clean and back to all factory settings.
