There are three main types of custom recoveries people install if they are planning on gaining root access on their devices. It doesn’t matter if you have a smartphone or tablet, a custom recovery is needed and not the stock recovery. After applying the steps below you can do more than just flash custom ROMs and firmware, it’s also a great place to take a Nandroid backup. Since installing a new ROM will always wipe the data clean, you should take the Nandroid backup before switching ROMs.

Details We Should Know
