How to Maintain Root through Any Upgrade

 (IE Forever Root, Motorola Devices Only)

Doing the following will allow your device to maintain root through any upgrade (unless Motorola changes things). I had no part in this and credit is posted below. Just feel it is something that needs to be posted and all RAZR owners should do before moving forward with any type of modifications to their device. That said let’s move on. I use root explorer, but you can also use adb pull and push.

RootExplorer Method
go to /system/bin/
open in text editor - mount_ext3.sh
add the following lines to the very bottom

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

ADB method
adb pull /system/bin/mount_ext3.sh
open the file in your favorite text editor
add the following lines to the very bottom

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

adb remount
adb push mount_ext3.sh /system/bin
adb shell "chmod 777 /system/bin/mount_ext3.sh"

Done!!!
