What is a GSI ROM?
GSI stands for Generic System Images and as is evident by its name, they are generic in nature, meaning they could be flashed across all the Android devices that are Project Treble compatible, aka which came with Android 8+ out of the box. As of now, near about all the devices are able to check mark this requirement. Moreover, these images are supported by numerous ROM developers, be it LineageOS, EvolutionX, Derpfest, PixelOS, and a plethora of others.

Before starting, please take a backup of all the data on your device. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.
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.

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.

So head over to Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging and OEM Unlocking.
STEP 3: Unlock Bootloader
