You don't have to foreverroot before the update. P3droid has put something together that's easy and works. I tried it myself having never rooted this bionic.[How To] Root (or re-root) after 5.5.893
In case you don't know...
1. Charge the battery to 100%
2. Boot into recovery
3. Wipe the battery stats ( usually under advanced options)
4. Reboot as normal, then use device until the battery is completely dead (do NOT charge the device during this time or you'll have to start over)
5. Once battery is dead, plug in to charger, wait minute or two, turn on device and boot normally.
6. Charge to 100%.
I am using different method,a battery calibration that you can download in the market(it's free).If this didn't work.Try to read my tips(my sig.).
