Well, I let my Atrix die out (I always like to get it to 0% before I recharge) and connected it to the charger. After it hit 5% I attempted to turn it on but it gets stuck on the red M (Motorola Symbol), and some times it goes to the ATT "Rethink possible" logo, but still ends up freezing on this. I have already called for a replacement, but I was wondering if I could unroot the phone if its stuck on this "red M" stage. I have to send this broken phone in so I want to unroot it before I do because having it rooted voids my warranty. Is there a way to unroot it this phone if it is stuck on the red M symbol? Is there a term for the phone being stuck on the red M? Softbrick?
