I know this will be considered blasphemy here....but I need to know how to unroot my daughters bionic. We bought the phone 2nd hand from a third party who mentioned it was rooted. I never considered this a downside until recently when it's preventing us from upgrading the software on the phone. I've tried doing a factory reset more than once, but the phone still won't accept the new software. Here are my questions: 1. How can I confirm the phone is rooted? Perhaps this isn't my problem at all... 2. Assuming it is, how can I either apply the new software while keeping the root, or unroot the phone to allow the software to apply. Thanks all for any help you can provide.
