What is Project Treble:
Project Treble basically partitions your device into two separate partitions, a system and a vendor: system contains your generic system image, while vendor partition has your device specific files required for booting and running your phone. This way we can easily change the system image and be able to run our device on different system images with the same kernel and vendor partition

S3VE3G hardware vs Treble implementation:
S3VE3G is an ARM and A-ONLY device. This means that regarding the GSI images (GSI = Generic System Image) to be used, you need to get ARM and A-ONLY system images.

Treble implementation and download:
Im working since last year and my first oreo build to let this project happen as we (guess what) dont received a official update with treble support.
So this is a work in progress...
This has been tested on a LineageOS and RR OREO GSI!!!!
It is possible to boot a Android 9 GSI with this vendor, but most stuff doesnt work.

THIS IS ONLY FOR THE SINGLE SIM VARIANT AS THE DUAL-SIM HAS A DIFFERENT PARTITION LAYOUT AND THUS WONT WORK!!!!!!!!!

Bug reports:
If u want to report bugs i need
- which GSI
- how to reproduce the bug
- a logcat

Current bugs:
- Camera (dont u ever expect this to work on treble our device is simply to old)
- Headset sound is bugged sometimes, turn the screen off and on and it starts playing

BE AWARE OF:
The infamous 3G bug. For some it works for others not and unless ur willing to rewrite your NV modem settings theres no solution for this.

How to fix the error in twrp: Failed to mount '/vendor' (device or resource busy)

 

[Thargorsson]

First post updated headset and 3g is fixed!
3G is currently samsung ril implementation so if it still doesnt work ill also do a qcril build.
U can flash the updates WITHOUT wiping data if u are already on a gsi.
Battery life should be a bit better but not perfect (need to deal with the camera daemon which things its still working )

can u send a screenshot?
also try formatting to a different fs type like f2fs and then format it back to ext4

images updated headphones now fixed without coping files on boottime.
If it doesnt starts playing on first attempt turn the screen off and on (this lets the audio DEEP_BUFFER flash which halts the audio before)

Oh man you are just a legend. Sadly i don't have a battery for my S3 Neo available to test your project sadly.

I did experimented with sGSI on my Redmi Note 4 some months ago and i would like to see the Redmi S2 or the Galaxy J4(Go) firmwares booting on our device with this method(Both are 32-bit).
