Before delving into the solution, it’s important to understand what NAND Write is and why it sometimes gets stuck in Odin.
NAND is a type of non-volatile memory that saves data when your phone is turned off. Before Odin begins to flash the new firmware on your Samsung device, it writes to the NAND. This is a crucial step in the process because if Odin fails to completely write to the NAND, it won’t be able to continue with the firmware update and you won’t be able to flash the firmware onto your device.
Fortunately, being stuck at NAND Write won’t harm your existing installation, and you can disconnect your phone from your PC and turn it back on to your current installation at any point. However, if you want to upgrade your firmware, you’ll need to get past the NAND Write phase that is currently stuck.
Fixing Stuck NAND Write Start in Odin 3.0
Here’s how to fix the issue of being stuck at NAND Write in Odin 3.0:
- Enable OEM Unlocking: Make sure that OEM Unlocking is enabled on your phone before attempting to flash firmware. If it’s not enabled, you won’t be able to flash the firmware.
- Use the Original Data Cable: We recommend using the original data cable that came with your Samsung device when connecting it to your PC for firmware flashing. A broken USB data cable could be the reason behind the NAND Write issue, so using the OEM provided cable is important.
- Update Odin: The version of Odin you’re using could be causing the problem. Try updating to the latest version of Odin, as this often solves the issue.
- Download Firmware Using SamFirm: The firmware that you’ve downloaded to flash on your Samsung device might be broken. If that’s the case, Odin will get stuck. We recommend using SamFirm to download firmware for all Samsung Galaxy owners, as it is a reliable source for firmware downloads.
In conclusion, if you’re encountering issues with being stuck at NAND Write while using Odin to flash firmware onto your Samsung device, following the steps outlined above should help you fix the problem and continue with the firmware update.
