Hello developers ( @kalyansundhar@govind1233 @lohanbarth @squid2),
I think everybody heard of project Treble. (Link, Link)
Of course Motorola isn't going to support it to our device(OTA update with repartition is very risky).
But somebody did already a unofficial port to the Xiaomi redmi note 4. This device isn't the same as the Moto G5s.
Today there is a developer doing it to the Xiaomi redmi 3s(Screenshots). This device is almost the same as the Moto G5s.
Specs of Xiaomi redmi 3s(Link)
Qualcomm MSM8937 Snapdragon 430
Adreno 505
5.0 inches
Accelerometer, gyro, proximity, compass
16 GB, 2 GB RAM
Specs of Moto G5s (Link)
Qualcomm MSM8937 Snapdragon 430
Adreno 505
5.2 inches
Fingerprint (front-mounted), accelerometer, gyro, proximity, compass
32 GB, 3 GB RAM
Do you developers think its possible for the Motorola G5s?
If this works we can make a lot of custom roms based on Treble.
Update
I think we must use OEM partition as Vendor partition.
Since a new partition was required for full treble we converted an unused cust partition into vendor which is almost 830mb in size, No we are not re-partitioning your device or anything else which may hardbrick your device

We could take one step at a time. First within the current setup, we should separate system and vendor libraries completely. There should not be any mix. Means /system/lib and /system/bin should have only system related. Similarly /system/vendor/lib and /system/vendor/bin should have only vendor related stuff. If we make the device work with this change, then it would be easy to make 'vendor' as separate partition. Even now we have /vendor folder in device root. This is just a symlink to /system/vendor, not a partition. In my opinion this would be a better way to go. Please correct me if I am wrong.
Thanks

What's wrong with this vendor tree? https://github.com/kayesk/android_ve...torola_montana
Project Treble on the Xiaomi Redmi Note 4
How did he do it? He used the “cust” partition on the device for his make-shift vendor partition. The cust partition normally holds a lot of device-specific stuff from MIUI, so it’s essentially wasted space on an AOSP build. Using the approximately 830MB unused partition, he moved the vendor HALs from system into cust without needing to repartition—which was a justification that OEMs such as Nokia and OnePlus used in their statements about why they weren’t going to bring Treble compatibility to their devices
We can use OEM partition. But what's the size of the OEM partition? And how do we make the HAL files?
We can also wait for the xiami 3s and port it to our phone.

There is nothing wrong with the vendor tree you mentioned. You take any device tree in github, you could notice mix of libraries and binaries in /system/lib and /system/bin folder. It was ok to have it mixed till Nougat. But with Oreo and with the introduction of HIDL, things are changed. In Nougat we had only one binder. But in Oreo we have 3 binders (binder, hwbinder and vndbinder). Inter process communication is dealt differently. Even with OREO the mixed setup would work. But If we want to go Treble route, then it is better to move out remaining vendor binaries and libraries from /system partition.
We can download the factory image of one of the Pixel like BULLHEAD, MARLIN, etc. And study how the system and vendor partitions are laid out in their OREO release. Theoretically a treble supported system image should be device and make independent (a plain android system). Boot and Vendor partitions would be device specific. I mentioned boot partition here because it would be having device specific boot scripts like init.qcom..., init.mmi..., etc.

@kalyansundhar
Can you use this?
Many thanks for your hard work.
Can you maybe release your software on github?
I want to used it for the Motorola G5s. Its almost the same device only I need not suc as vendor but OEM as vendor. But that can I fix if I have your code.
Yeah I have it for Moto Z play too but u need to wait until my isp fix my internet issues , so for now I can't upload the source sorry
I hope it can be fixed in 3 days

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
Read more about Project Treble
What's a GSI?:
A GSI literally means Generic System Image. It is a general system image meant for no specific device. Treble enabled devices have the capability to run a GSI. You can find a GSI here: Phh-Treble
ZTE Axon 7 hardware vs Treble implementation:
Our Axon 7 is an A-only device. This means that regarding the GSI images (GSI = Generic System Image) to be used, you need to get ARM64 and A-Only system images
What's Packaged in the zip:
A boot image (kernel)
A compressed vendor image (vendor)
Requirements:
- Unlock bootloader
- Installed patch EDL to add /vendor part. 800Mb
- Installed TWRP 3.2.1-8 - TREBLE
How to install:
- Format /system, /data and /cache, wipe /vendor
- Install Treble flashable zip package Project_Treble_v1.0-by-NFound
- Install GSI .img in /system part. How to flash a Generic System Image (GSI) on Project Treble supported devices
- Reboot
Alternative Instruction
Working:
Camera (and flashlight)
WiFi
Bluetooth
Telephony (Calls and Data)
Audio (Record and Playback)
Video Playback
Sensors
Broken:
Encryption (format data or remove encryption when coming from a non-treble rom)
Sepolicy is still permissive
Nothing else? Otherwise please report it!

Hey need fast answer! In this guide is talking about a Vendor 8.1 and 8.0 and 8.0 does not work with this rom, so my question is does this rom support your treble? https://forum.xda-developers.com/pr...development/aosp-9-0-android-9-0-gsi-t3826357

I am a bit confused: how would non-standard hardware like our famous DAC be used in a treble ROM? Would the vendor partition make specific APIs available for such non-standard hardware?
Thank you for this. Maybe its a stupid question, but does the DAC properly function even when we install a GSI?
I have a feeling that a proper fully functional treble will make the other custom ROM thread for Axon 7 obsolete.
so no EDL needed? I'm so happy because i dont have a windowscomputer.
*edit: i think i did not read good and windows is still needed

You dont need a windows-pc. Only twrp
Do we need to install the project treble zip in the OP if we already enabled treble by EDL?
Let me see if I got this whole treble situation straight :cyclops:
I'm running the latest AEX but I assume this guide contains a more updated "treble" so to speak, is that correct? In order to try the GSI's do I need to follow this guide and wipe everything or will the next AEX release update treble and contain the new fixes?

For this zip here he dont need a PC. For the EDL package yes.
Just wanted to thank you and talk about my experience.
Converting the device to Treble was a breeze. Can be done in under 5 minutes with no issues at all. I'm currently running Android P PR1 with no major problems.
However, when trying to install the GSI (totally not related to your work, but wanted to comment on this so everyone can enjoy treble) I ran into a small problem (error 7) when flashing the POST sGSI zip files. I resolved this by doing the following:
Install the treble zip
Install the GSI
Install the treble zip again
Install the 3 zip files in order
This worked out fine for me.
Again, thanks a million times on your epic feat. This is no small task, and is very welcome. It marks a before and an after.
You, sir, are heaven-sent. Thank you for your good work.

This is a TWRP fully Treble-ready with "Treble enabler" option in order to repartition safely the device.
Features:
TWRP fully Treble-ready;
Maintained with latest TWRP version;
Fully compatible with non-Treble devices - can be used as normal without Treble partitioning;
USB-OTG fixed
Has 'TWRP survival' function for automatically re-installing TWRP recovery when installing ROMs and kernels;
Adds a "Treble enabler" option that allows you to repartition your device in order to support Treble.
Has the option to shrink userdata to create Vendor partitions. All relevant partitions will be resized and formatted in one go.
If you shrink Userdata, it will ERASE DATA AND INTERNAL STORAGE COMPLETELY - but your device will stay compatible with all existing non-Treble ROM's
Instructions
Flash the recovery.
Reboot Recovery
Optional - Use the "Advanced > Treble enabler" option for repartition option.
If you opted to repartition for Treble, you are ready to flash a Treble ROM/Vendor pack.
About TWRP survival
TWRP survival is a simple hook that detects if a boot.img will be installed and restores TWRP after it's flashed. This only works if you have booted TWRP with Tissot Manager 2.0 from a real recovery boot - NOT from a recovery 'hot boot' (fastboot boot method).
You will see in the install log if a TWRP survival attempt is successful in the flash text output.
Automatic TWRP survival works when:
Flashing a ROM ZIP (or AIO) with TWRP
Flashing a boot.img in TWRP "Install Image" mode
Automatic TWRP survival does NOT work when:
Flashing a boot.img via fastboot
Restoring boot in a TWRP backup
Any other way of flashing a boot.img
In these cases, be sure the use the TWRP Installer immediately after flashing or restoring a backup - otherwise you may get the device into a confused state (especially if you restore a non-TWRP boot then try to install an AIO ROM without installing a new TWRP first).

FAQ
Q) After I flash TWRP, I get kicked into fastboot when trying to boot the ROM!
A) Your kernel is not Treble-compatible.
Q) How do I update TWRP?
A) Just flash the ZIP installer again, then Reboot Recovery. Note that this will erase Magisk on BOTH slots if you have it installed to either, requiring you to reflash it to one/both slots. See my Treble guide FAQ section for more info on Magisk interaction.
Q) My PC can't see the MTP (storage) device from TWRP!
A) For dualboot compatibility, MTP is automatically disabled at various points. Just enable it manually in the Mounts menu to get access.
Q) If I shrink Userdata for Treble, will stock and OTA work?
A) I have heard varying results on this. It does for some, not for others. Please assume that this will NOT work.
Q) Can I restore a non-Treble TWRP backup after I repartition for Treble? And the other way around?
A) Yes!
Q) I see "Failed to mount '/system' (Device or resource busy)" red error in TWRP after flashing a ROM
A) You can safely ignore it. You just need to reboot recovery before you can flash anything else (like Gapps) to this ROM.

But then I see no difference from a "normal" ROM ported specifically to a device. Should not Treble support be able to use them on several different devices?
For example, should not I be able to go to the AEX Treble download area and use it on ZF3? If it would not be the same as having to wait for a dev port AEX to ZF3.
I'm really confused lol

What do you expect? It's still in an early stage of porting. Some device specific bits still run from /system. GSI's may work but I doubt anything will work properly.
And I don't plan of supporting GSIs anyway.

Currently nothing much ( updated proprietary bits + vendor image taken in place )
Maybe in the near future when everything is in place. I'll seperate Vendor image from builds ( noticable smaller updates )

Well, repartition works fine. After repartition a new /vendor partition of 1024mb will be made.
Although, you'll loose your data (apps+personal). So make sure to do a full backup of your device.
Feedback:
* HAVE A BACKUP. This tool messes with your partition table and is still unstable. Your data partition can be resized to the wrong size.
Will come back after a few months to provide more feedback. Appreciate the work guys.
Works fine for me, data is correctly resized even with multiple changes from normal to treble and back...
Can't seem to wipe /cache partition.
Anyone knows why?

Well, that's normal.
Since you're going to make a new /vendor partition of about 1024mb, /data should be deleted & recreated in order to give some space to the new partition.
Also, what do you mean with "can be resized to the wrong size"?
The tool is pretty stable tho. Can you give more info such as model (ex. ZE552KL 4/64), script version (ex. 4.3b) & other?
Thanks.
I've successfully installed this tool, although attempting to install the new LOS 16 Android 9 ROM we have on this forum results in an error: 7, "Failed to mount '/vendor' (Invalid argument)"
From what I've perused so far in my research, that error mostly crops up on non-treble builds of TWRP, yet I definitely used the latest version from your website. I also redownloaded the latest version of LOS just to recheck, and yep, nothing's changed.
Any clue about what's going on here? I don't know much about Treble ROMs, or custom ROMing to be all honest.
EDIT: I have found the enable Treble option. Even when enabled and installed, after reboot, the /vendor partition cannot be read. It seems that after doing this too, I can't load files over USB, or mount my SD Card. I'm getting pretty confused as to what's happening. I can't boot into system, and fastboot won't connect to my PC.

Can i flash android Q gsi image using this recovery on ze520kl
I was able to compile the realme X2 Pro's official kernel release from https://github.com/realme-kernel-opensource/realmeX2pro-X3-AndroidR-kernel-source and I got 3 files generated in arch/arm64/boot folder.
They are:
Image
Image-dtb
Image-dtb-hdr
I just wanted to know how to move further to be able to flash just this kernel (I have a GSI image flashed on /system from TWRP).
Based on the partitions I saw from TWRP, the ones I feel relevant are: Boot partition, Dtbo partition, Vendor Image partition. Which one is it and how do I package the kernel/device tree blob file above to be able to flash to one of these via fastboot? Is that even a valid operation?
I don't want to risk a trial and error approach and possibly screw up further (I have backups of these partitions, but still I'd love to get some insights from the community who might've done this before)
Thanks!
For newer ROMs built, there is a term used frequently called RDP. RDP stands fir "retrofit dynamic partitions", which tries to mimic what Android 13 requires (dynamically sized partitins), but also compatible with older OSs. Here is a basic search result.

In a TL;DR perspective, its like the virtual filesystem expansion used by many PC OSs, but for droids. If you have not had the experience before, it just means that system, vendor, data ETC should be able to dynamically resize themselves to how the main operation system sees fit. We must keep in mind how much the base allocated predefined partitions were, as to not push the virtual filesystem beyond the limits of ~4GB.
A long time ago, ROMS were only built for "Olive". Then the "Olives" which also included the 8A variants. With the current main tree dev team, now includes the 439 family of chipset including the Redmi 7A. A simple glance at their subforums show some ROMS are also labelled as Mi, or SDM (Snapdragon Mobile) 439, which should also be compatible with olive.
For RDP ROMs, there are 2 required installations beforehand; an RDP enabled recovery and a converter. This converter currently requires an installed OS before hand, so please do not wipe anything yet. It is recommended to not install an RDP recovery without fully installing an RDP ROM to avoid misshaps. It is also recommended to reinstall a non RDP recovery to install a non RDP ROM.
First step for enabling RDP. ignore all the errors upon boot, and first installation. If there are flashing errors for 439 ROMs, try typing M|mi439 in Advanced - Terminal Emulator to temporarily change the device codename to M|mi439.
The only publicly available RDP enabled recovery is TWRP, there is a better recovery on Telegram, will await mod judgement later. Recoveries are also Android OS version specific and may result in errors such as bluetooth not working. An <A11 and >A12 specific Orangefox is preferred (please wait a bit).
