How To Fix The Samsung Galaxy S6 Null IMEI (Unknown Baseband)

Samsung Galaxy S6 Null IMEI (Unknown Baseband)

If you are a proud owner of a Samsung Galaxy S6, you may have encountered issues with the IMEI number and baseband version. These problems can arise when you tinker with the system partition by installing custom ROMs, mods, and kernels. The consequences can be dire, ranging from bootloops and bricked devices to the loss of the EFS folder.

The EFS (Encrypting File System) folder is a critical part of the system that stores essential information about the IMEI and baseband version. Unfortunately, there is a slight chance that flashing a custom ROM can corrupt this folder, leading to a null IMEI and an unknown baseband version. This not only blocks your ability to make phone calls, send SMS messages, and use mobile data but also disrupts communication with the SIM card.

In this comprehensive guide, we will explore various methods to fix the null IMEI and unknown baseband issues on your Samsung Galaxy S6. From flashing stock firmware to restoring EFS backups, we’ve got you covered.

How to Fix Samsung Galaxy S6 & S6 Edge Null IMEI

Flash Stock Firmware

One of the most common solutions to fix a corrupted EFS folder is to flash stock firmware on your Samsung Galaxy S6. This process replaces the custom ROM with the original firmware, which often resolves the null IMEI and unknown baseband issues.

To flash stock firmware, follow these steps:

  1. Turn on your Samsung Galaxy S6.
  2. From the main screen, go to “Apps.”
  3. Select “Settings.”
  4. Scroll down and select “About Device.”
  5. Tap on the “Software Update” option.
  6. If a pop-up message appears, select “Download” to start the firmware download.
  7. Wait for the download to complete.

By installing the stock firmware, you are essentially restoring the phone to its factory settings. This process has a high chance of fixing the corrupted EFS folder and resolving the null IMEI problem. However, it is essential to note that flashing stock firmware will erase all data on your device. Therefore, it is crucial to back up your important files before proceeding with this method.

Restore EFS Backup

If you are lucky enough to have a backup of the EFS folder before flashing a custom ROM, you can restore it to fix the null IMEI issue. Many custom ROMs automatically create a full backup of the IMEI folder, allowing you to restore it easily.

To restore the EFS backup, follow these steps:

  1. Turn on your Samsung Galaxy S6.
  2. Enable USB debugging mode. Go to “Settings,” select “Developer Options,” and toggle on “USB Debugging.”
  3. Connect your Samsung Galaxy S6 to the computer using a USB cable.
  4. Download the EFS Restorer Express.
  5. Open the app and run the EFS-BACK.BAT file.
  6. Choose a method to restore the EFS via Odin.

By restoring the EFS backup, you can bring back the original IMEI and baseband information, effectively resolving the null IMEI and unknown baseband issues. This method is highly recommended if you have a backup available.

Additional Troubleshooting Tips

Check IMEI Number

If the null IMEI problem persists after trying the previous methods, it is essential to check the IMEI number to ensure there are no serious issues with your Samsung Galaxy S6. You can do this by following these steps:

  1. Open the phone dialer app on your Samsung Galaxy S6.
  2. Dial “*#06#” (without the quotation marks).
  3. The IMEI number should appear on the screen. Make a note of it.

Once you have the IMEI number, you can contact your mobile service provider or Samsung support for further assistance. They will be able to verify the IMEI number and provide guidance on resolving any underlying issues.
