How to Install Android 10 or 11 GSI ROMs on Galaxy S9/S9 Plus!

Here’s how to install Android 10 or 11 GSI ROMs on your Samsung Galaxy S9 or S9 Plus! This is only for Exynos models that can have bootloader unlocked. If you want stuff like this, please buy Exynos models next time as Snapdragon U.S. models have locked bootloaders.

Follow along with written tutorial and links to files used in video.

NOTE: WE WILL ERASE EVERYTHING ON YOUR PHONE AS THAT IS REQUIRED TO INSTALL GSI SO PLEASE MAKE BACKUP BEFORE TRYING THIS AND ALSO WATCH THE VIDEO TUTORIAL BEFOREHAND!!!

This is ONLY for Galaxy S9 or S9 Plus but I will have another tutorial for newer Galaxy S10, S20, Note 10, and Note 20 soon!(much easier actually)
