NANDroid

NANDroid is a term commonly associated with the Android operating system, referring to a comprehensive backup of a device's NAND flash memory.

This type of backup includes all partitions and data, ensuring that a full system restore can be performed if necessary.

The concept of NANDroid is crucial for those who frequently modify their devices, such as installing custom ROMs or kernels.

It provides a safety net, allowing users to revert to a previous state if an update or modification goes wrong.

NANDroid backups are typically created and restored through a custom recovery environment like ClockworkMod (CWM) or TWRP Recovery.
