After much anticipation, the newest Android version, Android Oreo on the Samsung Galaxy S8/S8+ is finally here. The Samsung Galaxy S8/S8+ was released in April last year as the company’s flagship device. The device took the Android market by storm with its bezel-less display, lightweight and an abundance of features, all packed into a very thin form factor. The Samsung Galaxy S8/S8+  came installed with the latest Android OS at the time which was the 7.0 Nougat version of Android. However, after almost a year it is time for the next version of Android to hit the smartphones.

Android Oreo on the Samsung Galaxy S8/S8+ brings many new features to the Android experience. Some of which are: Picture-in-picture mode, notification channels, background app optimizations, notification snoozing, and more. Besides the new Android features, there are some other new features that are Samsung-specific such as a new keyboard with stickers and GIFs built in, the App Pair feature from the Samsung Galaxy Note8 and many more.

The build also comes with latest February security patches so you don’t have to worry about any major security vulnerabilities like BlueBorne, KRACK, and Spectre/Meltdown.So, all of that sounds good and you want to go ahead an install the latest Android update on your Samsung Galaxy S8/S8+? Well, you are in luck, thanks to the good people over at xda-develpers.com, who were able to pull the update which allows you to install it via the stock recovery.

In this guide, we will show you step by step how you can install Android Oreo on the Samsung Galaxy S8/S8+ Exynos.

However, before proceeding, a word of caution:

If your phone is currently running Android Nougat, then this should go smoothly. However, if your phone is running one of the Android Oreo betas, then following this method will require a factory reset/data wipe. We recommend backing up important data regardless. You can easily backup your data using this guide without any root in 5 minutes.

How to Install Android Oreo on the Samsung Galaxy S8/S8+ (Exynos)

Step 1 – Check Phone’s model number

It is very important that the model number of your phone be either G950F  (Galaxy S8 Exynos) or G955F (Galaxy S8+ Exynos). Currently, these two models are the only ones that can flash the Oreo build. If you do not have either of these models, do not proceed.

Step 2 – Download required files

If the model number of your S8 is G950F then download these files: AQL5 Odin and AQL5 to CRAP. If you have a G955F model then download these files: AQL5 OdinAQL5 to ZRA5, and ZRA5 to CRAP.

Step 3 – Copy the files

Now copy the OTA file that downloaded in the previous step 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.

Step 4 – Extract Odin

Extract the Odin firmware linked in the second step. It will be in a zip format.

Step 5 – Reboot

Power of your device and then reboot it into download mode by holding the Bixby button + Volume down + power.

Step 6 – Download Odin

Step 7 – Selecting the relevant files in Odin tool

Go to the firmware file that you downloaded earlier and extract the files into a folder. Now open the Odin tool and click the BL button that you see in Odin tool. 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. See the image below for further help
