How to Flash SuperiorOS GSI ROM on any Android Device

In this guide, we will show you the detailed steps to flash the SuperiorOS GSI ROM on your Android device. While many Android devices enjoy active support from the development community, there are a few that are left behind. Whether it’s due to the complexities involved, the device being less popular, or the OEM itself refusing to make the source code public, there could be quite a few reasons why they aren’t blessed with these ROMs when compared to their counterparts.

Fortunately, this is where the role of a Generic System Image comes in handy. As is evident by its name, these are “generic” and hence could be installed across all devices that came with Android 8+ out of the box [Project Treble supported to be precise]. Moreover, there are many noteworthy players in this domain that have already made a name for themselves, so which one should you ultimately opt for?

Well, if you are looking for a clean stock OS with tons of intriguing features which is then packed into a fast stable, and snappy OS, then flashing the SuperiorOS GSI ROM on your Android device might be the best bet. So without any further ado, let’s show you how this could be carried out.

STEP 1: Install Android SDK

First and foremost, you will have to install the Android SDK Platform Tools on your PC. This is the official ADB and Fastboot binary provided by Google and is the only recommended one. So download it and then extract it to any convenient location on your PC. Doing so will give you the platform-tools folder, which will be used throughout this guide to install the latest Android 14 GSI ROM on your device.

STEP 2: Enable USB Debugging and OEM Unlocking

Next up, you will also have to enable USB Debugging and OEM Unlocking on your device. The former will make your device recognizable by the PC in ADB mode. This will then allow you to boot your device to Fastboot Mode. On the other hand, OEM Unlocking is required to carry out the bootloader unlocking.
