How To Install Android Oreo on S8 / S8 Plus

How To Install Android Oreo on S8 / S8 Plus

1. Check your phone’s model number to see if its G950F (Galaxy S8 Exynos) or G955F (Galaxy S8+ Exynos). These models are the only ones which can flash the Oreo builds that are available now. If you do not have either of these models, do not proceed.

2. If you have a G950F then download these files: AQL5 Odin and AQL5 to CRAP. If you have a G955F model then download these files: AQL5 Odin, AQL5 to ZRA5, and ZRA5 to CRAP. (No, that’s not a typo, the build number of the official Oreo update really is “CRAP!”)

3. Copy the OTA file onto the SD Card on your phone. If you don’t have an SD Card, don’t worry as you can skip this step but you will still need the OTA file on your computer.

4. Extract the Odin firmware linked earlier. It will be in a zip format.

5. Reboot your device into download mode by powering off your device then holding the Bixby button + Volume down + power.

6. 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 4 of those will be used.

7. 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, CP, and HOME_CSC

8. Click start at the bottom of Odin.

9. 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.

The next steps will differ depending on what model you have. Please proceed to the right set of instructions for your particular model.
