I bought a used galaxy nexus and the ESN is clean but from some reason it won't let me swap it onto my account because when you try to reset it using the ##786# it doesn't do anything...the guy at sprint says that it must of been flashed so I'm thinking that someone flashed a jellybean rom on it...but I'm confused because the phone is locked I'm not sure if you can flash when the phone is locked...I only rooted a phone once and it was a htc hero so I'm not familiar with this Odin thing I see online but I NEED HELP BAD I NEED THIS PHONE!
