These include the likes of boot partition (where we flash stock boot.img or boot the twrp via fastboot boot twrp.img), the recovery partition (where we flash the TWRP via fastboot flash recovery twrp.img), the data partition (that stores all the data on your device), the EFS Partition (that stores your all-important IMEI number), the system partition (that holds the Android OS, in system.img format), the cache partition (for storing temporary data) among others. [Recovery and Cache Partition no longer exists in A/B Partition devices]. So if anything happens to your device, you could easily restore this backup and your device shall be up and running in no time. With that said, in some instances, you would have to wipe off all the partitions on your device. In other words, you will have to NAND Erase your device. When you do so, all the data in the aforementioned partitions will be wiped off. To re-setup your device, you will have to flash the stock firmware onto your device. But the regular flashing of firmware wouldn’t do any good. You will have to flash the Partition Information Table or PIT file alongside the firmware. For the unaware, a PIT file holds all the important information relating to the partitions present on your device, how much block size does each partition needs to have, among others. So you will have to load this file to Odin so that the Tool is able to read and identify all the partition files accordingly. Once that is done, it will then be able to flash the BL, CP, AP, CSC files without any issue. So without further ado, let’s check out the detailed instructions to NAND Erase and Re-Partition your Samsung device via Odin.
