On a Samsung S6 Deleted Texts Show Up Again After Deletion

Odin is mostly used past users to flash firmware binaries and custom recovery. However, Odin can also be used to re-partition, flash lock, decompress data, flash user data, and erase all data on Samsung Galaxy devices. You lot tin can even remove FRP (Factory Reset Protection) on Samsung and perform some very complicated tasks. In this tutorial, explain what Odin NAND Erase or NAND Erase All is, and how you can use it to erase all data and re-sectionalisation a Samsung phone or Galaxy Tab.

Actually, Odin is not merely a elementary flash tool for flashing the stock firmware. It is meant to be used just in the Samsung service centers by Samsung engineers to gear up non-functional Milky way devices. Do you lot know that Odin can flash or install the firmware on more than 60 Milky way devices at the aforementioned fourth dimension?

Anyway, let'southward keep our focus on Odin's 'Nand Erase' option. I know a lad who enabled Nand Erase in Odin while installing the firmware on his Milky way S9 just out of curiosity. Y'all know what, he ended upward with a bricked phone. Nand Erase had wiped all partitions on his S9 including EFS, boot, recovery, kernel & organization partitions. Fortunately, he was able to gear up his telephone by following ane of my tutorials published on another website.

NAND Erase Pregnant in Odin

NAND and NOR are actually two main types of flash memory, that is related to computers and it stores the BIOS settings to the ROM of a computer. Since Android devices don't have a BIOS, flash retentiveness or NAND relates to the bootloader and OS kernel that work together to boot Android devices into the system.

NAND is neither an acronym of a term used to express a boolean or logic gate "Not AND". Existence a not-volatile retentivity, it keeps the essential OS data even when your Android smartphone is turned off.

Thus, when it comes to Android, NAND retentivity stores the following partitions of your Android device.

• boot
• kernel
• recovery
• organisation
• information
• enshroud
• .android_secure
• datadata
• wimax
• efs
• preload

When you lot create a nandroid backup, an exact mirror all in a higher place partitions and directory structures are created. Similarly, when you perform a NAND erase in Odin, y'all wipe all the partitions on your Samsung Galaxy device. In simple words, you'll end upwardly with a device without an operating system. A sheer piece of hardware is all you lot get every bit the boot, kernel, organisation recovery, data, EFS, etc. take already been wiped. Obviously, your Samsung phone or tablet won't kick upwardly at all except to the Odin or Download Fashion.

Yous cannot set up a Samsung device after an unintentional NAND erase action by simply flashing the stock firmware. Since NAND erase wipes all existing partitions from the device's storage, you'll take to re-partition your device in Odin with the assistance of an appropriate PIT (Partition Information Table) file.

What is Re-partition in Odin?

As I already mentioned above, the flash or NAND retention on Android devices is divided into partitions and block structures. These partitions are essential to the proper performance of a device. It's the PIT file that tells Odin how much space to allocate to boot, kernel, system recovery, data, EFS. Not simply that, it is also responsible for the location and path of these sectionalization blocks on the internal storage.

The Re-partition choice in Odin is not meant to be used during a normal firmware wink. If you have to install a firmware, just add together the BL, AP, CP, and CSC files to Odin and practice not change the default settings.

The PIT file determines the construction, location, and size of specific partitions. Since a NAND erase wipes all partitions, the just way to re-segmentation your device using is to flash a PIT file that is strictly for your Samsung Galaxy device model and storage capacity. Flashing a wrong PIT may result in a semi-bricked device. Moreover, if you flash the PIT file of a 128GB device model on a 256GB model, your phone may exist configured to show just 128GB equally available storage. I personally experienced this outcome on my Nexus 6P.

Yous must not enable the Re-Segmentation option in Odin unless yous got the right PIT file. When y'all click the Pit tab in Odin, it will prove you a warning.

It means that you lot don't need to flash a PIT file in normal circumstances. In certain situations, when your Samsung device'due south division table is corrupted, flashing the PIT manually can be the only way to gear up the result. If you discover the IMEI number of your Samsung Galaxy phone missing, it might be due to corrupt EFS partition. Y'all tin restore the lost IMEI past flashing the Segmentation Data Tabular array. Yous tin follow these steps to wink merely the PIT file in Odin.

1. Boot your device into the Download way.
2. Launch Odin and connect your device to the PC.
3. Add together the BL, AP, CP and CSC binaries to the corresponding sections.
4. Select the Re-Sectionalisation option.

6. Striking the Start button on Odin await for the installation to exist finished.

Please go on in mind that the re-partitioning procedure will wipe your telephone's data so take a backup before yous proceed.

Steps to Re-Partition and Nand Erase using Odin

Finally, let'due south come across how we can perform a NAND erase in Odin and re-division a Samsung device past erasing userdata and all partitions. You can also fix your phone in instance yous accidentally or unknowingly erased all data. The steps described below volition also help you restore the lost IMEI on your Galaxy smartphone.

Below are the steps to flash stock firmware on Samsung devices with the Nand Erase and Re-partition option enabled.

Preparations and downloads
