A nandroid backup is considered as a good option before doing advanced operations on your device which possess great risks of data loss. Doing a nandroid backup keeps a copy of your Stock ROM and whenever you run into trouble or get bricked, it is just the matter of re-flashing the backed up copy to undo all the actions. 

Now let us see how a nandroid backup is done:

Requirements:

• Get the device charged to at least 70%
