Rooting a smartphone is something you should think twice about doing. More specifically, you will have to be a pro when it comes to using such a procedure. But one thing’s for sure: there are a lot of advantages to this sort of operation. However, if you’ve already rooted your Android handset and want to back it up and restore it, we recommend the following post.
After rooting the phone, you will have to flash a custom recovery image and then follow the steps we prepared for today.
It all starts with the booting of your Android phone into Recovery mode by doing this operation: switch the handset off and open it again with the help of Power. More precisely: hold down the latter button and the one below it down.
This is going to bring the custom recovery display soon. Of course, it all depends on the sort of smartphone you use (in the sense that there are different keys underneath the Power one). But that’s the general idea. Should you see a screen which says “!”, then you’re face to face with the usual recovery message available for Android devices.
You will need to return to Section I and perform a unroot and a root process, then get back. Afterwards you will be advised to perform full NANDroid backup by opting for Backup. How? With the aid of a trackball.
Another action you are required to perform is this one: wait till the handset backs up completely, then you will need to load the settings and other features you think are fit for the time being. If you wish to change things around, all you’ll need to do is simply return to this phase of our guide. And move the NANDroid backup on the device’s memory card. You must choose the phone’s root for a successful operation.
In order to reestablish a full NANDroid backup, you will be asked to take the backup directory and move it on the phone’s memory card, then reboot the device and enter in the recovery mode. Next you will have to opt for Restore. That should be followed by a couple of seconds of waiting, as the phone ends the transfer and you can move on to the next step: tap on Reboot phone and that’s all. The Restore option can also have a different name depending on the smartphone model you hold: either Nadroid restore or just Nand.
Other nota bene examples for our readers: it’s advisable to move the entire NANDroid directory to a laptop or whatever you may use. If the option we mentioned above isn’t called “Backup”, then look for something along the lines of “Nandroid backup” or “Nand backup”.
