Nandroid Backup refers to the full firmware backup of your Android phone. If you are an Android geek and keep changing or tuning or ROM then you should keep a backup of your firmware so that you can return to previous working settings anytime. XDA developer member Ameer1234567890 has suggested a great way of backing up your firmware or Creating a Nandroid backup without rebooting and entering recovery. This is a safe process and you will just need a rooted phone and busybox and terminal emulator installed. This will relieve your from the vicious cycle of rebooting into recovery and then creating Nandroid backup. Although, recovery mode is the best solution for the people who do backup ROM 1 or 2 times. But people like me who keep testing new ROMs and firmware need to create backup almost daily.
Custom Recovery like ClockWorkMod and TWRP are great tools for Android users who continuously play with their firmware. These recovery tools provides us to easily Backup current firmware and flash new firmware. But some time you are unable to access ClockWorkMod or want to perform actions without restarting the device. Here is an easy tutorial that will guide you through the procedure of flashing ROM package without booting into custom recovery. It is very easy to flash ROM or create Backup of ROM using Command prompt, you just need to have the super user access [rooted device] and connect your device to computer in USB debugging more and then you can follow the instructions below:
Pre-Requisite:
