Samsung is not very good at offering latest Android update even to their premium flagships. Even with the Galaxy S8 and S8+, Samsung rolled out Android Oreo update only to the devices running Exynos chip, but by any chance, if you have the Snapdragon variant of Galaxy S8 or S8+ (available for Verizon users), can now update it to official Android Oreo 8.0. However, officially there is no update aired by any carrier yet but it’s being expected soon.
The build mentioned in the process of install Official Android Oero on Galaxy S8 and 8+ Snapdragon Variant includes February security patch and almost all Android Oreo-like notification channels, picture-picture mode, notification snoozing and more.
The update has been certified in the Play Store and passes SafetyNet (XDA Thread).
Update Official Android Oero on Galaxy S8 and 8+ (Snapdragon Variant)
- The method of updating Galaxy S8 is for the model G950U or G955U, please don’t proceed if your device shows model other than that.
- You will need to download BRB1 Odin for S8 and update for S8 and the BRB1 Odin for S8+ and update for S8+.
- Copy the OTA file onto the SD Card on your phone. If you don’t have an SD Card, you can skip this step but you will still need the OTA file on your computer. Extract the Odin firmware linked earlier. It will be in a zip format.
- Now, turn off your device and then Hold the Bixby button + Volume down + power to boot your Galaxy S8 into boot mode.
- Download the Odin tool and plug in your phone to your computer. Odin is an official tool from Samsung that can flash official Samsung firmware onto Samsung Galaxy devices. In Odin on the right side, you will see 5 sections, but only 3 of those will be used.
- Click the BL button and navigate to your Odin firmware folder where you extracted your files, and then click the file starting with BL. Do the same for AP and CP.
- Click start at the bottom of Odin.
- Wait for your device to flash and then reboot. As soon as it reboots, power off your phone again. Then, boot into recovery once more by holding down the Bixby button + Volume up + power.
- If you have an SD card, select “apply update from SD card.” You can select this by using your volume rockers to navigate and the power button to select. After selecting the option, find the file called “update.zip” and select it with the power button.
- If you don’t have an SD card, select “apply update from ADB.” On your computer, open a command prompt by pressing Windows key + R and typing “cmd.” Once this command prompt opens up, type “adb sideload” and press enter. If you don’t already have ADB set up, you can follow these quick set of instructions to get up to speed.
