Android Pie 9.0 for Galaxy S9/S9 Plus! [Pixel Experience GSI ROM]

For those of you who want to try out the latest Android Pie 9.0 for your Galaxy S9, S9 Plus, or any Android device that has unlocked bootloader and Project Treble support, you can grab any of the Android 9.0 GSI(Generic System Image) ROMs and get it now instead of waiting for Samsung to update their TouchWiz, which most likely will take another 3-6 months.  And for those of you in the U.S. with U.S. Snapdragon models, it will be few more months than the international Exynos models as carriers have to re-add their carrier bloatware.  Now, these Android 9.0 GSI ROMs are NOT TouchWiz, they are not Samsung firmware but AOSP ROMs(What is AOSP?).

How to Install GSI ROM on ANY Android Device w/ Project Treble & Unlocked Bootloader! [TWRP Method]

For those of you who want to install Project Treble GSI(Generic System Image) ROM on your Android device with unlocked bootloader, you can use TWRP recovery to install them.  The process is actually not entirely different from flashing a regular custom ROM in TWRP, the only difference is that you will be using “Install from image” option instead of the default “Install from zip” option.  (If you don’t know what Project Treble is, please see “What is Project Treble for Android”.

What is Project Treble for Android?

Google has launched a new way of updating Android OS(Operating System) starting in 2018 called, “Project Treble”.   Although Google uses pure “100%” Android OS on their Nexus/Pixel devices such as the Pixel and Pixel 2 smartphones, many manufacturers like Samsung, LG, Huawei, Xiaomi, and others have added their own UI/skin on top.  In extreme cases like Samsung, they have added S-Pen features to their Samsung Galaxy Note series and lots of new hardware features not found in the original Android OS.  Due to this reason, whenever Google updates their OS from one iteration to another(such as Android 7.0 Nougat to 8.0 Oreo), manufacturers have to re-build the whole OS from ground up, causing months of delay in updates.  For example, Android Oreo update for Galaxy S7 probably took around 8 months.  This has been a troubling problem as Android OS updates once a year and by the time manufacturers update their software to the latest, they are already at least 6 months behind.
