Guide to NAND Erase Samsung Devices in Odin Tool

Flashing a Samsung device with the help of the Odin tool is pretty easy. It lets the user update to the latest available software. When you open the Odin tool on your computer, you must have noticed a feature called ‘NAND Erase’ or ‘NAND Erase All’. So what is it? Well, here we will be discussing everything you need to know about the NAND Erase feature in Odin and if it is useful or not. We will also answer a lot of questions including if you should enable it before flashing with a phone with any firmware or not? What to do if the feature is enabled accidentally before flashing?. Check out this blog post to know-it-all including the re-partition and how to install Samsung firmware with Nand Erase enabled.

What is Odin NAND Erase?

To simplify it, if you have ever installed a custom ROM or mod in your Samsung or any Android smartphone, you must be knowing Nandroid Backup which is offered by TWRP custom recovery.

Here, Nandroid Backup takes an exact mirror copy of your device which includes everything stored on your device including the Android OS the exact copy of various sections and partitions that EFA, cache, data, system, recovery, boot, kernel and others. Here, once you have removed all these partitions on your phone, you are left with nothing but a phone that won’t turn on and thus, you need to install stock firmware to do it.

Note that you can perform a NAND erase on your device but it will turn on and therefore, you will still a firmware to install. You can use Odin to install and firmware sourced from another tool called Frija firmware download tool.

When you perform a flash without NAND clean, you encounter certain problems. Since Samsung has a different firmware build for each model based on country, downloading the right firmware is crucial since a ROM used in country ‘X’ will encounter problems if you install it in the country ‘Y’. Frija helps find the right ROM for your device and Odin helps in flashing the device with the NAND Erase feature.

Should You Select Re-Partition in Odin?

The answer is it depends. If you are performing a standard firmware, you don’t have to perform re-partitioning. When it comes to Samsung’s firmware, the PIT (Partition Information Table) file is stored under the CSC file. When you click on the PIT tab on the Odin tool, you will get the said warning that says “Do not use this tab. This tab is for engineers. Your device will be changed with the pit in CSC file”.

To simply it, if your phone has 512GB of storage. However, if you install a stock firmware with the wrong PIT file of 256GB, your phone will be flashed with 256GB storage and the rest of the memory will be corrupted. Here, re-partitioning could solve the problem where you download the right firmware with the right PIT according to your phone and use the same flashing method as you would on Odin to install the firmware and rectify the issue. Also, go to the PIT tab on Odin to enable it when adding the right PIT file so that the whole process is complete without any glitch.

At times your Samsung smartphone might not boot after installing a stock firmware which is when a factory reset can fix the problem.

In case if you are unable to go to the recovery mode, a swift NAND Erase option is a great way to fix this and in fact, many such issues on your device. It also fixes issues like if IMEI is not showing or the device isn’t working properly.
