Android 12 GSI on Galaxy S20 (Exynos)? - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Is it possible to get the Android 12 beta 1 GSI working on the Galaxy S20? Considering that it has Project Treble support, is a/b, and (theoretically) supports DSUs? I don't seem to find any videos on this. Would be great if anyone knew how to get it working.
PS: DP3 works by simply flashing on TWRP but beta 1 fails to boot. Also, the fastboot method mentioned here doesn't work for the S20.

Did you solve the problem? Did you flash the Android Beta?

Port OP6 Android P beta to OP5T

Now that the 5t has official trebel support could it be possible for the .img of the P Beta from the 6 to be ported to the 5t with little effort? Maybe be even possible to boot without any kind of modifications if it's like a GSI.

Re. Android P DP4 treble GSI

Recently google released Android P DP4 treble GSI image. Being 'A type', Im flashing to flash it on RIVA but no luck. If i clean install, it boots to fastboot and if i install it over other GSI rom, It bootloops. any help? Anyone already working on it?
First of all google didn't released that gsi, its an unofficial port of the developer preview. Secondly, the gsi boots on 4A and for 5A as far i know sunny raj has got the success in booting it. I hope he will post soon.

Treble bootloop on G960F

Hello everyone,
I'm getting really frustrated hree as I can't flash any android 10 GSI. I either get bootloop, stuck on samsung logo or stuck on restarting on samsung logo.
Flashing different kernels seem to change the above behavior (instead of bootloop I get samsung logo and vice-versa).
I tried everything:
Doing the no-verity thingie...
Flashing stock files then GSI - nothing.
Flashing soldiers oreo kernel - nothing
Flashing endurance kernel - nothing
I can't find a vendor image that's compatible with any GSI on my phone. I also can't find any kernel that's compatible either.
So please, end my misery... if anyone managed to install android 10 GSI on this TREBLE COMPATIBLE DEVICE, please guide me through or provide any useful file (vendor img/kernel) that I might have been missed.
I wrote this because I couldn't find anything that could help... Thanks in advance!
EDIT:
I solved the problem with the kind help from phhusson and the guidance from Lanreallenjay (thanks, both of you!), so I'm trying to provide the solution for anyone that might be having the same problem as I had. So here it is:
For PIE GSI: use stock kernel/vendor (anything stock), flash the GSI, then flash Magisk -> it should boot fine now (only tested with phhusson's GSI. I had vibrating restart loops before, I wasn't installing magisk, that was my mistake)
For Android 10 GSI: same as above, but install the modded Magisk from phhusson's git (located @ v200 android 10 gsi post) instead of the normal one .

Hey, thanks for the interest!
I've got the S9 Exynos variant (SM-G960F, Europe), I unlocked the bootloader several days ago.
It's on android 9 right now, I flashed the stock firmware after I've tried everything to get android 10 treble to work and failed.
Current kernel version: 4.9.59-16947752 (stock)
Build number: PPR1.180610.011.G960FXXS7CSJ3
I can flash any rom available besides GSI (I've used lineage OS 16 for a couple of days).
If you need anything else more specific just ask, I don't really know what exactly can help with this situation.
Cheers!

After flashing G960FXXS7CSJ3 November stock firmware I can no longer flash anything.
(can't mount data partition)
When I try downgrading to G960FXXU5CSF2 June firmware Odin fails and the screen says:
SW REV. CHECK FAIL (BOOTLOADER) DEVICE: 7 BINARY: 5
November G960FXXS7CSJ3 seems to have upgraded the bootloader security, does anyone know a fix?

So from stock you flashed AOSP 10 GSI to system partition then phh's magisk (in TWRP) then it works for you?

Yep, it does. Buuut the rom is not stable at all, I've got random reboots/ crashes when opening settings and such, not usable at all. I'm on ONE UI 2.0 beta now which is much more stable (daily driver stable actually).

Have you tried formatting data with TWRP (to the part when it asks you to write "yes") then flash no-verity?
You should at least be able to flash TWRP. If you can't, just download the proper USB drivers for your device, it might be the culprit.
Cheers!

Phh just hinted it's likely Pie vendor causing panics:
"First you need to flash stock rom. Then install magisk and then this gsi.
Though please note that on Pie vendor, S9 kernel panics and reboot every few minutes, so it is highly unusable."

Camera quality might be fixed with Google cam, if you find a good port.
Not to derail the thread but I just noticed after installing Android 10 beta 2 Treble Info now reports my S9 supports Treble A/B, curious no?

Wait what? That's interesting...
Can someone with more experience enlighten us about the differences between the A only and A/B?
A\B

No real experience but A\B devices have two slots ie double the partitions (OnePlus has 67) .
This allows updates to be installed while running from slot A while the updated system is copied to B.
Apparently Q requires A\B so now we're on Q may as well try that next time we're curious
Phh just released:
AOSP 10.0 v208
Fix suspend/dt2w for Samsung Q vendor
Fix backlight for Samsung Q vendor
Samsung Q's fine, love gestures but the bloat is killing me.
You can tell Q's going to be so much leaner without bixby & friends.
Glad we installed it to get compatible but I think now we probably stand a better chance with 10 GSI's, hopefully LOS17 & Pixel Experience get updated again soon.
Wondering whether to following the rooting instructions yet?
Phh did say "flash stock rom then magisk and then gsi"

The differences between Android 9 and Android 10

I recently brought Rmn8p with miui 11.0.6 (global) , wait to unlock bootloader. After that flash preloader & lk then trwp and root.
I was wondering what's the difference between android 9 and android 10? Is it almost the same like I read at some post? Someone has updated to android 10 may share some viewpoints with us, thanks!
Already unlocked bootloader , root and xposed , phone recorder installed. Thanks to those pioneers.

Hey. I think this is widely discussed elsewhere. Just search for "MIUI Android 9 vs MIUI Android 10" in Google or YouTube. You'll find way more information there than you would ever find here regarding such generic topics. Have fun ?

Google Android 12 beta 1 GSI (AOSP)

Hello,
I tried to boot A12 beta 1 AOSP GSI from Google which includes GMS. I am running a A/B device with Qualcomm Snapdragon 765G chipset and 6/128 GB memory. I can boot the GSI perfectly but there is no sound in the system! Also brightness slider is not working...
In phh-treble GSI ROMs, there is options to fix Qualcomm audio, alternate screen brightness scale etc.
How to fix audio and brightness issues in A12 beta 1 GSI ROM?
One of my friends who flashed the GSI is also facing no sound bug. So, probably you'll have to wait till beta 2 for that.
i tried the aosp_arm64-exp-SPB1.210331.013-7333779-3227774b.zip but the device stucks on bootlogo.

Check which props are set in these options (see phhusson's github) and use adb setprop ..... to set them.

It gets to the middle then it says install failed
Searching with Google, i found that it wirks only of some device. That whas build from a10 (my mia3 have pie when i bought it). I think it depends from this. It's appearead because i have installed i custom rom. It' a shame because beta 2 seems better than beta 1... With more functions and bug fixed. But there's already a good port for mia3 with stock android 11... For users who want to try android 12 experience

You should just wait until android 12 is fully released.
