3) Create back-up for all the data of the tablet.

4) The Nexus 7 should be rooted and have ClockworkMod (CWM) recovery installed.

5) If the device is stuck on boot or experiencing boot loop then perform 'wipe cache partition' and 'wipe dalvik cache' few more times before rebooting.

6) The Nexus 7 should have above 80 per cent of charge.

7) The tablet should be factory unlocked and not be locked to a particular network carrier.

8) The SlimBean Build 3 ROM used in the tutorial below is compatible only with Google Nexus 7, applying this on incorrect variant might brick the device. Therefore, verify the model number of the device by navigating to Settings>> About Tablet.

[Note: Use Volume keys to browse between options in the recovery mode and the Power button to select an option.]

6) Perform a Nandroid backup of the existing ROM which can be restored later if the new build does not work or if users wish to go back to the previous ROM.
