How To Guide GSI / Treble on S22 Ultra Exynos

[bhammler]

I've spend some days with testing GSI on my device. It's now my daily driver. Here's a small guide:

1. making a clean install (Odin) and unlock the bootloader

2. flash TWRP as recommended

3. best ROM I've found is SuperiorOS_v414-arm64-bgS-slim-secure_20220611
(https://github.com/phhusson/treble_experimentations/wiki/Generic-System-Image-(GSI)-list)
In PixelExperience the fingerprint scanner is not working and with CherishOS I had some issues

4. I've used GSI-Flasher to flash the image in twrp (https://xdaforums.com/t/how-to-make...ung-galaxy-a51-super-partition-image.4216083/)

5. Then: factory reset, reboot and all done

6. for Magisk you can unsecurize through phh settings

What is not working:
- can't get 5G, VoLTE and WiFi-Calling working (but I can live without it, because Samsung OneUI is too much overloaded for me)
- S-Pen: I never use it
- Zoom over 10x
- automatic brightness (I use velis autobrightness. Works perfect)

What could be better:
- haven't found a good GCAM yet. I use this one: GCAMGO_3.3.439_SHAMIM_V1.apk
- the sound is fine, but could be louder and more bass

Attached some screenshots and phh-settings

Video record sound is still broken?

I have tried some gsi`s and this fix was not working

 

[bhammler]

I've flashed this in twrp - maybe play with the "disable audio effects" in phh settings (samsung & misc). Mine are not checked and it's working

Excellent, thank you very much, were you able to test if Android Auto works in the car with the multimedia connected?

small research guys:

best of tested GSIs is now CRDROID, everything`s working and battery life is 9-10h SOT, with heaveier usage, no gaming, maybe it will be 12-13h, will report, but the most important, IDLE drain 0,5-0,8%/h,so over night i am loosing just 5-7%(8h of sleep)

I have also compared log errors in tested GSIs and CRDroid have just few sometimes, other GSIs were hot while using and charging or using on Sunlight.

What is not working on anz GSI is AUto brightness.

First started with:
SPARK OS - FP, face recogn working, battery good, gmail crashing

ARROW OS - no customization
AWAKEN OS - same as SPARK OS, Wodproof or maybe another apps cant connect with Google login
CORVUS - a lot of customization, GMaps not working, after 3-4 installations for few hours, in AA is overheating and discharging, not usable
SUPERIOR - not so much customizations as SPARKS or AWAKEN OS or CRDROID, PIN unlock only with OK button

CRDROID - for now best one.

Will test PE, Descendant and Statix soon.

if you have another Q, just ask.

PS: banking apps working on every GSI(magisk hide, safetynet fix, Zygisk).

[bhammler]

yes CrDroid is the best for now. Did you find a good working GCAM?

this one:

Download GCam Mod for Samsung phones

Pixel Camera (a.k.a. Google Camera) is a camera app, which comes pre-loaded with Google Pixel smartphones. Introduced in April 2014, the Google Camera was supported by every Android smartphone running on Android 4.4+ and higher. But now, this app is exclusively available only for Google Pixel...

Does anyone know if this process will work with the SM-S9080 (the unlockable snapdragon vers)? I have that phone in the mail as we speak, but the ability to run pure android on the Ultra is my dream device and I would turn around and grab the exynos version when I can.

sims functional on crdroid?

 

[CarlosEHidalgo]

Work on Samsung S22? Not ultra

 

[japanicana83]

UPDATE: I would like to confirm that this process *does* work on the S9080 with the crdroid GSI and the snapdragon twrp. Sim card, Wifi, lte data, fingerprint, and front/rear camera work, but probably needs a modded g cam to get good quality photos.(which I have not tested any yet).

Obviously I will not flash any exynos specific mods

Both, no problem, 4g data, no volte.

On any phone based on specific arm

For snap you need to use another config file, try searching
