Does 6.1 support Treble?

[UPDATE]
Confirmed to support Treble by "ali ba".
Hello all,
I've read lots of conflicting news about the support status of Project Treble in Nokia 6 (2018),
Can anyone confirm the support or the lack of it once and for all?
Thanks.

Correct me if I'm wrong but every device launching with 8.0 has to support Treble does it not? I guess the problem lies with whether Nokia will provide the ability to unlock the bootloader. I'm not sure if it makes a difference that this is an Android One device in this respect.

Does anyone have an official firmware available for download? I have TA-1054, China version and it seems it has a custom firmware. Thank you.

You're absolutely right, the problem is the Chinese release was on Nougat, and nobody has yet ran the Treble flag test on the international version.. maybe because not so many hands got it yet... We'll wait..

According to the test app it does support Treble, but I'm not sure whether to trust it.
Came with an update out of the box and I didn't check the version before applying it (which would have made that clearer).

Thank you very much!!! finally some useful results, I think we can trust the app, but just to make sure, could you please follow the procedure described in this page.. more specifically the terminal flag test..
https://www.xda-developers.com/project-treble-android-oreo/
Also, do you own the Chinese device or the international one?

If we trust the app, then also A/B updates should be enabled.

EU-version, shipped by Amazon.

Here is a screenshot from Treble Check on Nokia 6.1
(TA-1043/Europe/Android 8.1 update/Shipped with Android 8.0)
Code:
$ adb shell getprop ro.treble.enabled
true

Hi, same here. Do you have any news? Have you managed to install unmodified Android to your TA-1054? Will appreciate any info.
Thanks.

Nope, no news yet.

Can someone tell us the difference between all Nokia 6 2018 models please?
TA-1068
TA-1045
etc...
Is there a specific model for 'Worldwide' like Nexus/Pixel?
Is there a Europe version?
...
...
THANKS!

[Update]
Just noticed you actually did just that... Thanks.
I think this is an important topic that deserves it's own thread..
Would you care to start it?, also what models are sold in what markets?
That would be useful.
cheers.

Try to obtain the global firmware of TA-1054. I can provide you with the firmware.
I have two Nokia 6.1 devices. One is TA-1054 and the other is TA-1089. Both Global/International/Made in India version. I have the firmware files. But I doubt, you'll be able to flash them with the Stock recovery in your Chinese Variant. If you want the links, I'll provide you. And yes, Nokia 6.1 supports Treble. And I've recently flashed Android 11 GSI. Well, only issue was unlocking the boot loader to flash custom recovery. I never want to bootloader unlock any other Nokia phone anytime soon.
The TA-10xx naming determines the variant of the phone. The (4 + 64 GB) variant is TA-1089. The values change depending on the ram and storage size. Also newer models for the same phone we're released with Mediatek processors and Snapdragon for different markets. Just like Samsung does, sells the Exynos variant in Asia while selling the Snapdragon variant in US, UK, EUR, etc. Nokia also started doing this with their Nokia 5.1 and 5.3( if I recall correctly, not sure). So those phones have multiple variants. The TA-10XX naming scheme is quite similar to RM-xxx scheme followed by Nokia in the past, when Nokia was owned by Nokia and not HMD. In fact, their shift to TA-XXXX naming suggest that they belong to the family of Android/HMD owned Nokia and not the old Nokia. Even the 3310 (The beast) and 8110 4G have TA-XXXX product code instead of the RM-XXX. It's like a product code which can determine the RAM, Storage and Chipset as well as Region of the device.
So to flash Android R, TWRP or TWRP based custom recovery is required. Then flash any Android 10 Custom ROM with Treble support. Also flash dm no verify.zip with the ROM. Reboot to set up device. Don't add any Google account and password, etc. Then again boot into TWRP, changed to Image mode from zip mode in Install. Flash the system.img from Android 11 GSI.
Then reboot.
Follow the guidelines to unlock your bootloader

Rom compatibility

Hi! i'm new at the Samsung world, i've always used Nexus phones, that you can install any rom over anything and it will boot, and i really want to install an Android 9 ROM. My question is about compatibility between devices, i have an Argentinian SM-G9600, can i install an android 9 rom for a SM-G960F? i didn't find information about and don't wanna wait for a non-comming update (i'm stuck at september patch.....)
thaks a lot

No.

Your device is a snapdragon model and the G960F is an exynos model

I said 960f just as example, but there's is any variant I can use?

How to get an S9 G960U1 rooted?

I tried today to root this phone in all sorts of ways, but mainly I got stuck at the first step of getting a custom recovery, I found the twrp files for my phone, but when I tried to flash the file in Odin I got an error of "secure check fail : recovery"
I tried different versions of Odin.
I also tried t use fastboot, but it couldn't recognize my device, (adb devices shows my device, while fastboot doesn't [and of course I'm in download mode])
I've tried all sorts of drivers, from universal drivers to the specific one for my device from the Samsung website, fastboot still didn't see me device...
I have no idea what to do now...
I managed to get an official stock firmware update, that's all I was able to do...

AFAIK, root isnt possible for the 960U's, only the 960F's

I think I saw someone write they were able to root it.. though I couldn't find it again for some reason...
Also, it's supposed to be an UNLOCKED phone with the U1 software... I don't understand how or why it cannot be rooted (or change to a custom ROM)...
Hope someone know how to get it done

"Unlocked" means carrier SIM unlocked. Different thing.
All Qualcomm Snapdragon variants have locked bootloaders that prevent rooting. Except the Chinese variant - the lone exception.
There was an exploit found last year that allowed rooting for one of the Qualcomm variants but can't remember which, and newer firmware may have since blocked the exploit.

Is it worth trying to install firmware (official) for the g9600 phone (China Snapdragon)? And from there if that was successful, would I be able to use CROM to OEM unlock?

nope. it will very likely fail at the Odin flash process. you can if you want to, but im betting it will fail. Hell, i even had to use a modded Odsin just to flash another carriers firmware on mine, but it worked like a charm. That being said, it was all within the same basic model info, what youre proposing isnt

I'll try the modded Odin, if its a fail, I'll probably give up

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!

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.

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."

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"

Trying to downgrade to Android 8 or preferably 7 with Odin

I have long tried to downgrade my phone SM-G955F to Android 8 or 7.
I have tried many different firmwares but they all seem to fail on installing the new bootloader. I can always recover back to Android 9 using a collection of files called AP_G955FXXUCDUD1_CL21427293_QB39365969_REV00_user_low_ship_meta_OS9.tar.md5
Can anyone point me in the right direction for a ROM running android 8 or 7 that I can root.
Essentially I do not care if it is stock rom as long as I can root the device. I have successfully rooted my devices running android 9 using magisk but the essence is that I need to run android 8 or 7 and being able to use google chrome as a browser.
Any help is much appreciated
Best regards,
Erik

Hi,
1) Download the .zip file of the light ROM : https://forum.xda-developers.com/t/s8-s8-nougat-01-jan-2020-v30-lightrom.3636154/
Then magisk.zip, search it on the internet.
2) Flash the ROM via a custom recovery
3) Then flash magisk.zip
