working on it.

Some forums talking about it:
SO if I update to GIngerbread do I lose my Z4root?
Z4Root Not working after GB 2.3

After the Gingerbread OTA update, my Droid 2 R2D2 went into Root limbo. I no longer had root access. z4root no longer worked. You couldn't delete the superuser files either.

I followed steps on and Unable to Re-Root Droid 2 after Gingerbread OTA

  • Make sure you have the Motorola drivers installed.
  • Download Psouza's one-click root package and extract the contents:
    This is supposed to be for Windows 7 and later. I tried the Windows XP/2K3 package, but it didn't work for me.
  • Make sure USB Debugging is enabled on your device. This should be under Settings -> Applications -> Development -> USB Debugging.
  • Run Pete's Motorola Root Tools.exe and choose Temp ADB Root. (I tried click on Unroot My Phone, but it failed.)
  • Open a command prompt and navigate to the support_files folder where you extracted the contents of the package.
    adb shell
    The $ sign will change to # Type:
    busybox mount -o remount,rw /dev/block/mmcblk1p21 /system
    What goes after /dev/block may be different for your device. You can type "cat /proc/mounts" and see where /system is mounted.
    cd /system/bin
    rm su
    rm busybox
  • Run Pete's Motorola Root Tools.exe and choose Root My Phone.
  • Opened up Titanium Backup and verified Root access was granted.
  • Updated Su binary.
