What if you accidentally select this option before flashing any firmware in Samsung devices? In this post, we will know all about Odin NAND Erase, and how-to install Samsung firmware with Nand Erase and Re-Partition options enable.
What is Odin NAND Erase
Lets first know what “NAND Erase” option in Odin? If you ever install any custom ROM or any Mod in Android device, then you must be familiar with “Nandroid Backup.” TWRP(Team Win Recovery Project) custom recovery offers Nandroid Backup. The Nandroid backup provides to create a backup of all partitions and structured directories on the device.
So when you backup your device using Nandroid backup via TWRP, it backup completely device’s Andoird OS. It creates an exact mirror of everything present on your Android device. When you want to restore your device, It restores the backup, all the partitions of your device in the previous stage at the time of backup.
Once you restore Nandroid Backup via TWRP recovery, it restores all the partition of your device. When you erase NAND on Samsung device, you wipe all those partitions like a boot, kernel, recovery, system, data, cache, and EFS partitions. If you remove all those partitions, then it left nothing so you need to install Stock Firmware via Download or Odin Mode on Samsung device.
If you only NAND erase on Samsung device, it doesn’t boot up. To boot your device you need to install stock firmware on your Samsung device by Odin tool. In case you don’t know how to unbrick Samsung devices or about “Nand erase all fix” then your device must be unstable.

The standard-issue if you flash stock firmware without Nand clean, you see some minor problems. Samsung released firmware for their devices in-country based.

Usually to install a stock firmware in Samsung devices via Odin. Just need to add AP, BL, CP, and CSC or HOME_CSC files in the corrected slot in the tool and click on the start button. By default, the ‘Auto Reboot‘ and ‘F. Reset Time’ options are checked. If you want to perform a normal firmware flash, then don’t need to select Nand Erase or Nand Erase All, Re-Partition, Flash Lock and Device info options.
Should You Select Re-Partition in Odin?
