How to install the One UI beta on the Samsung Galaxy S9 and Galaxy S9+

Samsung recently launched their latest One UI beta for the Exynos Samsung Galaxy S9 and Galaxy S9+. One UI is Samsung’s newest version of Samsung Experience, formally TouchWiz, based on Android Pie. This beta was launched in Germany, South Korea, and the United States. The US has been a bit luckier and all the Snapdragon Galaxy S9 series devices have already had the builds leaked.

Thanks to XDA Senior Member SoLdieR9312, we now have the OTAs for Exynos phones along with firmware.science for the Snapdragon phones. If you install these updates you will not receive OTA updates from your carrier or Samsung.

Here is a video on the XDA TV YouTube Channel showing how to install the OneUI beta on your device. Use the download links below for the files and the video for instructions.

Samsung Galaxy S9 update Galaxy S9 Forums

1. First, download Odin 3.13.1, the update.zip for BRJ6 to ZRKA, and the BRJ6 Odin files.
2. If you have an SD Card in your Galaxy S9, copy the update.zip to the SD Card. If you don’t have an SD Card, skip this step.
3. Open the Odin files. The zip will be named SM-G960F_1_20181031161553_2yj261n7q7_fac.zip. In it, you will see six files. In Odin, you will see 5 categories, though you will only use 4.
4. Put your Galaxy S9 into Odin mode by turning it off then holding Power + Volume Down + Bixby button.

Open Odin and put the corresponding BL, AP, CP, and HOME_CSC, but nothing in Userdata. This might erase all the data on your phone.

1. Hit start.
2. Your phone will flash the new firmware and then reboot.
3. After you do this, wait about 5 minutes and then shut off your phone and reboot into recovery by holding Power + Volume Up + Bixby.
4. Now use the BRJ6 to ZRKA OTA for this update.
5. Use the volume buttons and power to select “apply update from SD card.” If you do not have an SD Card, skip to step 12.
6. Use the volume buttons again to select the update.zip file and the power button to select it. The update will then start. The update can take between 2 to 10 minutes. Once you finish this step, skip to step 13.
7. If you don’t have an SD Card, use the volume buttons to select the “apply update from adb” option. Then open a command prompt/Terminal on your PC and type:

   adb sideload <file location of update.zip>

and hit enter. The update will start and take 2 to 10 minutes.
