Also posted this on the XDA forums because I'm genuinely interested in finding a solution, not just for myself but for future owners as well. I think this is a pretty fair, albeit challenging, question... So I've been suffering from the infamous Bionic connectivity issues as of late. I've called in for a few replacements and it looks like tomorrow will be my last one. So here's the conundrum... My original Bionic was forever rooted way back when. Sure enough, with the most recent Bionic software update, .902, my USB just stopped working on this device. Works fine on the replacements, but with this one it just says "USB Device Not Recognized." Obviously I need to unroot this phone so I can send it back in. Did some troubleshooting with a member from DF, we were able to remove root without having to plug it into the computer by deleting some files from the /bin and /xbin system folders. This was verified with root checker. HOWEVER, we are unable to remove the Superuser app. We tried a few things, like booting it into different modes and trying to uninstall, with absolutely no success. I've uninstalled/reinstalled the newest Moto drivers several times. So my question is this...how can I remove an app like that without having to plug my computer into the PC? Please help me!!! I really don't want to take the risk of sending this in and being charged $500!
