How to Root Galaxy S8 Plus on Android 8.0 Oreo Official Firmware

You can root your Samsung Galaxy S8 Plus by using this tutorial. Galaxy S8 Plus shipped with Android 7.0 Nougat, and after almost a year, the device received the first major system update. The new Android 8.0 Oreo has also started rolling for the Qualcomm Snapdragon variant, which means, all the Exynox devices have already received it.

However, once you upgrade your device, you will lose your root access. Fortunately, we have a complete guide on how to root Galaxy S8+ running Android 8.0 Oreo.

You can read the guide below to root your Galaxy S8 Plus on the latest firmware using TWRP Custom Recovery and Magisk tool. Thankfully, the device got official TWRP support, and hence the rooting will be easy.

Our choice of root utility is always Magisk, thanks to the system-less approach and compatibility. But before actually performing the tutorial, please make sure to backup all your data as no one knows when something goes wrong. These procedures sometimes wipe your system partition which may result in data loss.
