Droid Bionic Owners Beware; 5.9.902 Update Breaks Root for Some Users
The Motorola Droid Bionic has been updated to 5.9.902 via an over the air update that started this week. 5.9.902 brings a host of new features, improvements and fixes. You can view the full changelog from Verizon here. Some of the more notable improvements include fixes for black screen lockups, dock lockups, idle resets and improvements to the camera and several system apps.
While some users maintained root after the update, XDA users began reporting in this thread that the update did, in fact, disable root access. Those that used the ’43V3R Root’ method have reported success preserving root after updating. All current root methods have been unsuccessful in rooting .902 after the update.
Is there any hope for those who already applied the update? Forum members have confirmed that it is possible to downgrade to .893 with RSD Lite, so take solace in the fact that you can flash to stock and start over. If you haven’t updated yet, XDA Senior Member tuckmobile has created a step by step guide to rooting, applying the permanent root script and updating to 5.9.902. You can check out his full guide here or just the instructions to apply the update here.
