Potential Permanent Root Method Released for Motorola Devices: Bionic, DROID3, and DROIDX2 Included

A potential permanent root solution has popped up for Motorola devices (including the Bionic, DROID3, and DROIDX2)  that you should be able to complete in about 5 minutes time. You have to be rooted already (instructions), but from there you just need to edit some lines in your “mount_ext3.sh” file using Root Explorer. Now, there is a chance that Moto could (will likely) patch this up in a new update, but you might as well attempt it anyway if you love having root access.  

Instructions:

1.  Using Root Explorer, head into /system/bin.
2.  Hit the Mount R/W button.
3.  Scroll down to find “mount_ext3.sh” and long press on it.
4.  Choose “Open in Text Editor.”
5.  Scroll to the very bottom and add the following lines:

chmod 4755 /system/bin/su
chmod 4755 /system/xbin/su
chmod 755 /system/app/Superuser.apk

6.  When finished, press Menu and “Save and Exit.”
7.  Hit the Mount R/O button and reboot.
