Galaxy S8 and S8 Plus One UI update are now available to download. You can easily install One UI on your Galaxy S8/S8+ using the tutorial given below! We have also provided the direct download link to the One UI Pie firmware for Galaxy S8 and S8 Plus. Read ahead.
The firmware version comes with build numbers G950FXXU4DSBA and G955FXXU4DSBA for Galaxy S8 and S8 Plus respectively. The OTA weigh 1.6 GB approximately. But before proceeding to the manual tutorial, make sure you had checked for the automatic update by navigating to Settings > Software update option on your phone. If the update is available there, you can easily do the automatic upgrade. If not, you can proceed to the tutorial below and manually update Galaxy S8 / S8+ to Android 9.0 Pie One UI official firmware.
This update is now rolling out via OTA (Over-the-air) in several regions including Germany, India, and the Netherlands. But those who were already participating on the One UI beta program are still not getting the stable update. If you are one of the beta users, or you are still on the stable Oreo, this tutorial will be perfect for you. The instruction given below will get your Samsung Galaxy S8/S8+ to Android 9.0 Pie One UI official firmware using Odin software and stock recovery.
Why manual update via Odin?
Manual installation of Samsung stock firmware is required for the following reasons:
- Bricked device: In case, your Galaxy S8 has been bricked while trying any custom ROM or mods, you can manually update your phone to recover and get back to stock position.
- OTA problem: If you aren’t getting direct OTA from Samsung due to carrier or region problem, you can download Samsung stock firmware and flash it to your phone using Odin tool.
- Rooted device: Rooting opens the window to customize your Android phone. But sometimes, this root status can break the OTA links. That’s why you might not be able to update your phone directly.
- Custom ROM: If you had installed any custom ROM like LineageOS, it is inevitable that there is no way to get official OTA. You need to flash the PDA and other files using Odin to get back to stock ROM.
- Bootloop: Facing bootloop issues due to some root apps or some Xposed modules? Manual update will help you!
