[Motorola Droid Bionic] msmith0957:
I will try to briefly describe the steps I took to get to where I currently to give you an idea of what I tried.

stock

root + 4ever root (R3l3AS3DRoot_Windows_V2.1)

"restore bionic only" option - to upgrade, losing root

OTA Upgrade to .893

root + 4ever root - FAILED

"restore bionic only" option

root + 4ever root - FAILED

pete's moto tools - ROOT FAILED (PetesMotorolaRootTools_v1.07)

pete's moto tools - UNROOT FAILED, cant 'su' of course, trying anything at this point.

What should I do from here?? I want to run .893, rooted. Any other methods I should try?
