So, what is Nandroid Backup?
Android’s open nature has allowed the developers to do the impossible things on a very small sized device. It takes a few minutes to change the whole system of the device, there is a plenty of tweaks that can be made to the device, a number of custom ROMs comes out every second and a number of MODs is there that adds charm to the functionality of a device running Android OS. One can backup all the apps, apps with data, media content, contacts, call logs, sms messages and anything else on an Android device easily. There are third party apps to perform these tasks, like Titanium Backup, Contacts, SMS backup and restore, Call logs backup and restore, Helium and others that have made the lives of Android users easier more than a lot. Users do not need to worry about any data loss and they can tweak their device the way the want because it’s easy to get their data back within no time.
Well, that was one part of backing up some data from an Android device, but how about backing up the whole system? Whole system means, the operating system of an Android device, including all the system data, system apps, system settings, each and everything and that’s called Nandroid Backup. In short, the backup of the Android operating system in a device is called Nandroid Backup. The very advantage of this Backup is, once you’ve made it and you tweaked / flashed your device and something goes wrong during this process and ends up soft bricking your device, you’re safe even now because you’ve created a Nandroid Backup and flashing Nandroid Backup will take you to the last working state of your Android device within a few seconds. Nandroid Backup is also useful if you’re phone has got some radio issues after flashing something weird, the old system will definitely bring back the working Radio that was present in the device at that time and give your device it’s life back. Now the point comes how you can create this Backup and how you can restore it and where is it store on your device, well let’s discuss it now.
