Samsung recently launched their latest OneUI beta for all variants of the Samsung Galaxy S9+ and Galaxy S9++. The beta was launched in Germany, South Korea, and the United States. Thanks to an XDA Developers user, we now have the OTAs for both Exynos and Snapdragon variants for the devices. If you’re sick of Oreo and want in on the Pie, here’s how you sideload it. Since the update is an unofficial one, you won’t get OTAs from Samsung and will likely have to sideload the official Android Pie image once it’s released.

Galaxy S9

  1. For the international (Exynos) Galaxy S9, download Odin 3.13.1the update.zip for BRJ6 to ZRKA, and the BRJ6 Odin files. For the US (Snapdragon model) Galaxy S9 download Odin 3.13.1, the update.zip for U3BRJ5-to-U3CRKE,  and the Odin files. It is important that you get the files corresponding to your variant as sideloading an incorrect update will involve in a complete wipe of your device. It shouldn’t be a trouble, though. All international variants run an Exynos SoC while the ones sold in the US and China run a Snapdragon SoC, so keep an eye out for that.
  2. For the Exynos Galaxy S9, copy the update.zip to the SD Card. The zip will be named SM-G960F_1_20181031161553_2yj261n7q7_fac.zip. In Odin, you will see 5 categories, though you will only use 4. Put your Galaxy S9 into Odin mode by turning it off then holding Power + Volume Down + Bixby button. Open Odin from your computer and put the corresponding BL, AP, CP, and HOME_CSC, and nothing in Userdata. This might erase all the data on your phone.
  3. For the Snapdragon Galaxy S9, the zip will be named G960USQU3BRJ5_G960UOYN3BRJ5_VZW.zip. In it, you will see six files. In Odin, you will see 5 categories, though you will only use 4. Put your device 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, and nothing in Userdata. Corresponding files, in this case, can be found in the ODIN zip file and will be labelled accordingly
  4. Before hitting start, ensure that you have all important data backed up and that your phone has at least 60% charge. Once you hit start, your phone will begin the process and reboot.
  5. After a successful reboot, put your phone into Odin mode again.
  6. Use the volume buttons to navigate through the UI and power to select “apply update from SD card.” This step is the most important as it sideloads the actual update files to the device. The process can take anywhere between 5 to 10 minutes.
  7. Reboot your phone and once it boots to Android, you should be running OneUI.

Galaxy S9+

  1. For an international (Exynos) model, download Odin 3.13.1the update.zip for BRJ6 to ZRKA,  and the Odin files. For the US (Snapdragon model), download Odin 3.13.1the update.zip for U3BRJ5 to U3CRKE,  and the Odin files.
  2. For the Exynos Galaxy S9+, copy the update.zip to the SD Card. The zip will be named SM-G960F_1_20181031161553_2yj261n7q7_fac.zip. In Odin, you will see 5 categories, though you will only use 4. Put your Galaxy S9 into Odin mode by turning it off then holding Power + Volume Down + Bixby button. Open Odin from your computer and put the corresponding BL, AP, CP, and HOME_CSC, and nothing in Userdata. This might erase all the data on your phone.
  3. For the Snapdragon Galaxy S9+, the zip will be named G965USQU3BRJ5.zip. In it, you will see six files. In Odin, you will see 5 categories, though you will only use 4. Put your device 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, and nothing in Userdata.
  4. Once you hit start, your phone will begin the process and reboot.
  5. After a successful reboot, put your phone into Odin mode again.
  6. Use the volume buttons to navigate through the UI and power to select “apply update from SD card.” This step is the most important as it sideloads the actual update files to the device. The process can take anywhere between 5 to 10 minutes.
  7. Reboot your phone and once it boots to Android, you should be running OneUI.

If this is your first time sideloading an update, we’d recommend that you sit this one out and wait for the official build. If things don’t go well or you want to get back to Oreo, you’ll have to wipe your device and sideload a stable Oreo build again. Alternatively, you could even use Samsung Smart Switch for the job.
