So here is a short post, which will help you to completely make a backup of your device using NANDroid using CWM.

Creating a backup for an android smartphone is as important as creating one for a computer. We often end up instating third party apps, side loading APK’s and experimenting new ROM’s, with all this there is a significant chance that we might end up losing some data or even hampering the ROM.There are many tools available in the market to back up android devices which can help in recovering for such above mentioned situations. We will be discussing about one of them today known as NANDroid.


The name NANDroid has come from NAND. NAND is also known as the permanent flash memory that is used by a device to store the basic necessities to help it run. This does not include any functional or cosmetic change. A NANDroid backup is used to create a echo copy of an android device. The hacking community knows NANDroid as a standard directory structure. This backup can be used to save personal data and system files.

To recover a NANDroid backup we need a recovery application which supports Nandroid Backups. CWM and TWRP are the two basic applicationsavailable which support NANDroid backups. Once you are ready to flash, you can boot into the recover and create a backup for the same.
