Hey Guys today I wanted to share a little tutorial on GSI so if you guys didn't know the One Plus 6T supports Treble Natively So with that being said you can Flash GSI

I am on latest 9.0.11 I have not tested any other firmware

WARNING IM NOT RESPONSIBLE IF YOU GET A BRICK OR YOUR PHONE SELF DESTRUCTS JUST USING MY KNOWLEDGE TO FIGURE THINGS OUT FOR OUR USE

OFFICIAL INSTRUCTIONS
This arent my steps I found them looking around and decided to test and add Some Things from my part and finds all credits of these steps go to the author of the thread.

The correct installation procedure of a GSI on the One Plus 6t
Make sure you unlocked the bootloader and that you have the latest ADB and Fastboot from Google, I used minimal ADB worked fine for me but CAUTION if it doesn't download the latest ADB from google

Now in Fastboot flash, the following, WITHOUT rebooting in between! this needs to be done all in one go!

THE FIRST STEP DO NOT MISS
First Step
Boot to Twrp and you need to flash the avbctdisable.zip

2nd Stage
fastboot flash boot_a boot.img
fastboot flash boot_b boot.img
Use the STOCK boot image!

Then flash the GSI system image of your choice

ON A/B Partition

fastboot flash system_a gsi.img
fastboot flash system_b gsi.img

Replaced by the first Step Ignore
Then flash STOCK vbmeta image with the specific commands!

Command for VBMETA
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img



ONLY USE A/B ARM64BIT GSI

Continue to Next Steps
---------------------------------------------------------------------------------------------------------------------------------------------------
Extra steps I had to do When flashing if you are flashing any GSI DO NOT FLASH TWRP AFTER

STEPS After GSI flashed
1.Boot TWRP thru Fastboot
2.Wipe Data and Dalvic Art Cache
3.Flash the TWRP installer
4.Reboot to System
5. Reboot To Twrp Flash Gapps
6. Reboot To Twrp Flash Magisk And Optional Custom Kernel
7.Reboot
8.Profit

I just installed Corvus GSI ROM following the above instructions, wifi works fine, almost everything works fine... only one thing is bothering me bad... I cannot adjust the brightness, it burns my eyes. I found a video on youtube in which it is said that this is something general for GSI... it's a sin! Anyway, thank you @carbon271!

I'm trying this with the Android 12 Beta 5 GSI, starting on OOS 9.0.11, but ending up in a bootloop. Has anyone else had any success with Android 12 GSIs on the 6t?
