So first this first a little explanation. There aren't any device specific roms for the Moto G9 family, and im too lazy to learn how to.

HOWEVER, luckily for us, the G9 is a Project Treble compatible device! This means that it can flash and boot Generic System Images (GSI). These roms are device unspecific and can be booted on any android device which came with Android 10+. For more info click here. The long and short of it means we have a path to get to Android 12. I used the Pixel Experience ROM, but you can use any GSI Rom as long as you select one that uses the a/b partition scheme - Links to some other ones at the bottom

The only issue I have come across so far is NFC not working. If I get it working I will update this thread

otherwise you will run into weird errors installing larger roms

As soon as you reboot hold power + volume down to get to bootloader and select recovery. If it boots twrp, congrats it worked

I am interested in the topic of the GSI, I have a concern.
Have you tried the GSI's that Google uploads on its developers page? Are they as functional as the GSI's published on GitHub?
It is that I am interested in these GSI, I have investigated and nobody talks about them except for Google itself.

Thank you very much. I already chose a GSI to flash. Let's see. Thank you.
