Few questions XZ2c regarding Treble-Support - Sony Xperia XZ2 Compact Questions & Answers

Hi all, im tempted to buy this XZ2 Compact as a secondary phone (LG V30 as main)
but i just got a couple questions befor im buying it:
Is this device part of the official Treble-Project devices? (so no need to make vendor partition myself etc etc..)
can i unlock bootloader on pie (if it already has official pie)? (dont really care for DRM as im not a camera person.)
if the above bootloader question is false answer; can i unlock bootloader on oreo then upgrade to pie? (to update vendor partition for pie GSI's (if treble supported)
Thanks in advance.

this is a A/B device, so yes it has treble, don't know if official or not, but I think it is a regular treble-phone
PIE is official, but you can't officially unlock on PIE at the moment, so you have to unlock while running oreo, then update to pie

Hi! I'm curious: Have you or has anyone else tried a GSI on the XZ2 Compact? On this Github page (1) it says the camera isn't working at all. Can anyone confirm or deny? I'm interested in getting the phone, but wouldn't if the camera doesn't work with GSIs.
(1) github.com/phhusson/treble_experimentations/wiki/Sony-Xperia-XZ2-and-XZ2-Compact
Sorry, can't post links yet.

I have not tested a GSI, but as far as i can say, it depends on the aosp source from Sony devs.
And afaik the Sony devs pushing updates for the camera to their aosp code, which hopefully lead into a working cam in the next few releases.
But i think @MartinX3 is the more experienced guy related to this topic.

I never feel experienced enough :silly:
As far ass i know, only the sony aosp works with the Q GSI, because Q needs a new treble level.
It splits the sepolicy.
The sony aosp & its OEMv7 blobs are compatible with it.
I am not sure if the PIE stock rom has it.
But I think they will only implement it with stock Q in combination with a Q bootloader.

As to Treble, yes, the XZ2C supports Treble. https://thedroidguru.com/list-project-treble-supported-android-devices/
The bootloader is supposedly unlockable (and Sony's dev site provides for it), although I cannot comment on the consequences of doing so, such as the DRM issues with the camera.

Due to the MediaTek processor, that's closed source, developers can't really develop for this device without breaking the law. MediaTek have always ensured that their source code isn't released making it difficult for a developer to actually make a custom rom. It's just unfortunately not going to happen for this device.
The Sony XA2 has a Snapdragon 630 processor so it's likely it will receive some more development than XA1. If you want to root you Sony XA1 device you can use on of links below.
XA1 Plus: https://forum.xda-developers.com/xa1/development/xperia-xa1-plus-stock-kernel-advanced-t3729856
XA1 & Ultra: https://forum.xda-developers.com/xa1-ultra/development/g3221-built-sources-t3622886
Best of luck!
There is no breaking the law or anything. And Sony has uploaded kernel sources long back.
Here is the one for .162 FW
https://developer.sonymobile.com/do...rchives/open-source-archive-for-40-0-a-6-162/
The stock ROM is pretty awesome and there is little reason to unlock BL and make/install custom ROM.

Possible. yes.
But there is a chance of a brick.
Different firmwares may have different partition setups.
And if you brick the one with IMEI or Bootloader ,the phone is a brick.
The only way to confirm is a developer having a rooted UAE phone and a rooted Indian phone and mapping the partition tables.
or perhaps , peek into ftfs and then predict the partition setup. :victory:

is there anyone who can guide me...??
i don't want to buy a new device,:laugh:
The main issue i found is a lack of device tree from Sony, one would need to be built to even consider doing custom roms, LineageOS etc etc, i recently got this phone and i am rather disapointed with the lack of roms for it, ROM's could be ported to the phone no doubt, i know how to build roms and port, but doing a device tree is beyond me

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..

Also, do you own the Chinese device or the international one?

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.

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

If your device came with Pie (9.0) preinstalled. In India, few devices came.

when I wrote that was because a developer managed to start a rom 9.0 with few bugs (same errors as the roms 8.1) other developers are working to start a rom based with the new resources of the stock 8.1 (on YouTube you can see a part of their work mixed with the vendor of kalil in a video of lineage16 for cedric but it is not the final work nor will it be) if you want to know more you have to enter the cedric groups in telegram either brazil, english or spanish that are where you can find to the developers and the work that is being done for this device a little abandoned translated with google translator

The honor v20 supports treble however honor hasn't enabled it.
And emui 9.1 is in beta stage not magic UI 2.1 (skin of emui 9.1 which is what the honor view 20 is set to get in may)

From where did you get it?
All devices launched with Oreo should support treble or else they won't get certified by Google. V20 supports treble.

I phrased it wrong.
The honor view 20 does support treble however it doesn't support treble ROMs as well as seamless updates.

Seamless updates are not much a issue. For that you need two partitions A and B which implies more ROM space is reserved for system . Only a few devices have A/B partition.
Supporting treble and being able to flash treble compatible ROMs are completely different things.. If you want to flash a treble ROM or GSI (or any custom ROM) you need to have an unlocked bootloader.. Which is officially not possible now.
You could flash a treble ROM which was signed by Honor.. But there are none which I am aware off..

Question Downgrade?

Hello, am new to pixel device... My previous device was Xiaomi Mi 11 , my device carne with A13 !my question is there any way to downgrade to A12 I want to flash derfest A12 my fav ROM .. thx in advance
Hello, welcome to Pixel land.
First, in order to flash a factory image, you'd have to unlock your bootloader. If you don't know already, click the yellow How To Guide quick filter at the top of the list of threads in this section and you'll find 3-4 threads that tell how. I also have a link in my signature below - you can use the link for the Pixel 7 Pro - the instructions to unlock the bootloader are the same, and the OP of my Pixel 7 Pro thread is much better organized than my one for the Pixel 6 Pro, in my opinion.
After that, the only way you can downgrade (and have everything working, and not brick your phone is to use one of the two Android 12 Developer Support images for Pixel. There's an Android 12.0 build from February and an Android 12.1 build from July. They will never receive updates, however.
You can always manually flash a Pixel 6 Pro stable Factory Image to re-upgrade at a later date, or use the Official Google Android Flash Tool (OEM Unlocking needs to be toggled on - you may not have to manually unlock the bootloader - the "site" will do that on its own) to re-upgrade.
Any of the stable Android 12 builds at that factory image link should not be flashed because the Android 13 bootloader cannot be downgraded to an Android 12 bootloader, and if you flash everything from 12 Stable but the bootloader, it'll appear to work at first, but it truly won't work correctly - it will not be useable.
If you unlock the bootloader, you should also make sure the Android 13 bootloader is flashed to your inactive slot as well, to avoid the possibility of accidentally bricking your new phone.
Thanks for the fast reply sir much appreciated .. I got the idea ... My device stock unlocked and rooted .. now my question is if I flashed the July A12.1 developer ... Can I flash custom ROM based on A12.1 like derpfest etc ... Sorry I mixed up things here little harder than xiaomi

You're welcome. I don't fool around with custom ROMs except on my 6-year-old or more phones, so I can't answer that question. Part of the best things about having Pixels is the software features Google starts off exclusively on the Pixel stock ROMs.
