I would love to root the phone but it won't power on. It's actually my roommates phone and I'm posting on her behalf because her phone is a brick now. I even hooked it up to the computer without the battery and it still won't power on. It's an expensive phone and its less than a year old. I unlocked & rooted my HTC Evo 4G and i wanted to unlock & root her Nexus as well but now it won't even power on. Not sure if anyone has had this particular problem with the exclamation point in the battery icon & won't accept a charge. Please help. Does she need a new battery or should she send her phone to Google for repair?
