Install GSI on S9 Exynos

[arunrawat2112]

Guys I successfully installed HAVOC-OS located https://forum.xda-developers.com/project-treble/trebleenabled-device-development/gsi-havoc-os-t3930030. The steps I followed are mentioned below
1. Wipe everything except internal storage.
2. Flashed BRK3 Vendor https://mega.nz/#F!wFFQUYbI!GZvNOBSn1wVn8U9mQDzBiw!IQsjlYzA
2. Installed Endurance GSI kernel https://forum.xda-developers.com/galaxy-s9/samsung-galaxy-s9--s9-cross-device-development/kernel-endurance-kernel-v1-0-t3849434
3. Flashed the system image for ARM 64 A only
4. Boot system
5. Reboot to recovery and Flashed Mgisk
6. Gapps will fail to install at first. Just goto wipe -> Adv wipe -> system partition -> Resize. Reboot to recovery and flash Gapps
7. Reboot and enjoy
8. You can test other GSI Roms also and report. The thread is located at https://forum.xda-developers.com/project-treble/trebleenabled-device-development

Thanks buddy. I was looking for the ways to run the GSI. And the method works. Good job

thanks for the guide! im still on an unrooted s9, but if everything works ill definetly make the jump. Can you tell us more about stability, bugs and if there are things not working

So after testing the ROM for 2 days I can say that
1. It is very stable and can be used as a daily driver
2. Everything works, I am not sure about Bluetooth audio though, haven't checked it
3. It can be heavily customized. Unlike LOS, where we have only few of these features available
4. Battery life is the best I got using any other ROM out there (check the screens below). and I am the guy who gets 3 hrs of SOT, when others claimed 5+ hrs on the same ROM.
5. Security patch is latest even as compared to the TW ROMs
6. Regarding camera... Its the same as LOS pie. Use gcam by idan 3.5 fixed and you are good to go.

Thanks for trying this out. I'm only a few months in with my exynos S9 on android pie, so I haven't yet learned the details about rooting/recovery for this phone.

I'll wait for your next update regarding daily use, and would love a more detailed step-by-step for installation if that's not too much trouble. I'm honestly loving those screenshots.

How about IMEI, BRK3 Vendor safe..?

Ok here is the detailed tutorial on how to install a GSI rom

1. First you need to wipe everything in TWRP. Just like you do, when you clean flash any rom

2. Than install the BRK3 vendor. Link is provided by the OP. It's a flashable zip file so just flash it like any other zip.

3. Flash the Endurance GSI kernel. Link is in the OP.

4. Next, download the GSI rom from the link in the OP. Remember to download the ARM 64 A-only variant.

5. Extract the files and you should get a . Img file. Copy that in the SD card

6. In the TWRP, goto install. Select flash image from the bottom right corner of your screen. Now browse the image file, that you copied and choose system image and install.

7. Boot to the system and than boot back to the recovery.

8. Now flash the magisk

9. If you try to install gapps, it will give an error regarding space. So just goto wipe -> advance wipe > system repartition > resize
After resize, you will be able to install gapps.

Flash gapps, automatic brightness fix ( link in the rom thread), AOD fix ( link in the rom thread) and reboot.
