ClockWorkMod (CWM)
=====================================
ClockWorkMod recovery is a recovery image that let's you do some funny things like make a nandroid backup, installing custom rom and much more
This is not necessary for root

NOTE: if you install CWM you won't be able to update your tablet with the OTA firmware from ASUS, until you revert back to the stock recovery

Do you wish to install clockworkmod recovery? [y/N]n
