However, if you have the Exynos variant of the Galaxy S9 and S9+, then you can go ahead and update your phone to One UI 2.5. If you live in Germany, you can update through an over-the-air update from the settings menu. But if you are not eligible for the update, you can manually download and install the firmware on your phone. Check out below to learn how to.

Download and Install One UI 2.5 OTA Update on Galaxy S9 and S9+

Warning: As we mentioned above, the update is available only for the Exynos variants of the phone. Please do not try this tutorial if your phone has a Snapdragon chipset. Any attempt will result in you bricking your phone. Please proceed at your own risk.

1. Over-the-air update

The first thing you should try is to update through OTA (over the air). This is the easiest and quickest method of updating. If your phone is eligible for the update and you live in Germany, you can update to One UI 2.5 by following these simple steps:

  1. Go to Settings.
  2. Scroll down and tap on Software Update.
  3. Tap on Download and Install.

The phone will check for any available updates. If there’s any update available, the phone will download it and you will be able to install it. However, if the phone does not find any updates and it says that the software is up to date, the OTA update has yet to reach your phone. In this case, you need to manually download and flash the update, as explained below.

2. Manual One UI 2.5 installation with Odin

This method is somewhat lengthy and complex. But if you follow the tutorial below step by step, you will update your phone in no time.

Firstly, you need to download some tools that are required for this process. There are two things that you need to download: Odin and Frija.

Download both of these files on your computer. Both files are stored as archives. Extract both of them and put them in a single folder.

Getting prepared

  • Go to Settings > About Phone > Software Information. Quickly tap 7 times on Build Number to enable Developer Options. 
  • Go to Settings > Developer Options and tap on USB Debugging. This will allow your phone to communicate with the computer to install the new firmware.
  • Install the latest drivers for the Galaxy S9 (Download)
  • Go to Settings > Developer Options and enable OEM unlocking.
  • Make sure you have at least 60% of battery life left. If your phone gets stuck during the installation process, it will not turn off.

Go to the folder where you extracted Frija and double tap on “Frija.exe” to open the program. You need to enter your phone’s model number. In this case, it is as follows:

  • Galaxy S9: SM-G960F
  • Galaxy S9+: SM-G965F

The second field you need to fill is CSC. This is an important field because it is the code that finds the proper German firmware. In this case, you need to write DBT. Once you have filled both fields, click the Download button. The firmware will be downloaded and stored on your computer.

  8. Now connect your phone to your computer. The ID:COM box on Odin will turn blue.

Odin will now flash the Android 10 One UI 2.5 firmware on your Samsung Galaxy S9 and S9+. The flashing process will take a few minutes because the firmware is massive, weighing just under 5GB in size. The phone will automatically restart when the installation process is finished.

Now the phone will take around five minutes to boot up. You need to set it up and enter your information. To verify that everything is up to date, go to Settings > About Phone > Software Information. The number under One UI version will be 2.5. That is all you need to do. Your phone is now updated to the latest version.
