Odin NAND Erase Explained

So, what does Nvà Erase in Odin mean? If you have sầu been into lớn flashing custom ROMs on your Android device, you must be familiar with the term ‘nandroid‘ & ‘napp android backup‘. The napk utility present on custom recoveries like TWRPhường gives the user an option khổng lồ create a backup of all partitions và structured directories on a device where the following data are stored.

Universal Android Partitionsbootrecoverykernelsystemdatacabít.android_securesd-extOEM-specific Partitionsdatadata (Samsung devices)wimax (Samsung devices)efs (Samsung devices)preload (Samsung devices).cust_backup (Huawei devices)flexrom (Acer devices)mmcblk0_start (Acer devices)custpack (Alcatel devices)mobile_info (Alcatel devices)appslog (HTC and Sony devices)uboot (MTK based devices)

So, when you create a ngame android backup through Recovery Mode or standalone scripts, the napk utility creates an exact mirror of everything present on your Android device. When you restore the backup, all the partitions are restored lớn the exact condition they were at the time of backup.

The reason why I listed the partitions on Android devices is to lớn explain the meaning of NAND when it’s mentioned in the context of Samsung devices. When you erase NAND on a Samsung device, you wipe everything including boot, kernel, recovery, system, data, cađậy, & EFS partitions. When all these things are erased from your device, it’s left with nothing except the Download or Odin Mode và the hardware.

Having performed a NAND Erase, your Samsung Galaxy phone or tablet won’t boot at all. và if you don’t know how khổng lồ recover your phone or about a “nand erase all fix”, your costly device will become unusable. Below, we’ll see how to lớn install a Samsung firmware with Nand Erase and Re-partition options enabled.

The comtháng practice during flashing a stoông chồng Samsung firmware using Odin involves just adding the AP, BL, CPhường, and CSC or HOME_CSC files khổng lồ the appropriate fields & hit the Start button. By default, the ‘Auto Reboot‘ and ‘F. Remix Time‘ options are checked by mặc định. You aren’t supposed lớn play with options lượt thích Nvà Erase or N& Erase All, Re-Partition, Flash Lock and Device info at all during a normal firmware flash.

Should You Chechồng Re-Partition in Odin?

Well, that depends on the situation. As I said above, you don’t need lớn bởi that in normal circumstances. Usually, all Samsung firmware have sầu a PIT file inside the CSC file. When you cliông chồng the PIT tab in Odin, you’ll get the following warning.

Suppose you purchased a 512GB variant of the Galaxy S10. And, after installing a firmware you’re shocked to lớn see that your phone’s storage is reduced khổng lồ 128GB. It’s because of PIT corruption or flashing the PIT meant for the 128GB Mã Sản Phẩm on the 512GB Mã Sản Phẩm.

In case your device’s partition table has corrupted because of a bad firmware flash or any other reason, you can fix your Samsung phone or tablet using the Re-Partition option. You should check the Re-Partition option in Odin only if have sầu to flash a PIT (Partition Information Table) tệp tin your Samsung. Make sure that you have the correct PIT tệp tin.

Moreover, you aren’t supposed to flash only the PIT tệp tin. You must flash a PIT along with the 4 firmware binaries, namely AP.., BL, CPhường, and CSC. Also, you must enable Re-Partition in Odin’s PIT tab. In my case, I am flashing a PIT tệp tin on my Galaxy S9+.

Sometimes, your Samsung phone or tablet might refuse to boot up properly after you have installed a firmware. Your Samsung device might get stuchồng on the Samsung biệu tượng công ty and won’t get past it. In many cases, the issue can be fixed by performing a data factory reset via stock recovery. However, in some cases, you might not be able khổng lồ access the Samsung recovery mode. What would you vì then? You can try re-installing the firmware but that may not help you.
