[AOSP 8.1] [2019-03-06] Phh-Treble - Treble-Enabled Device Development A/AB ROMS

WARNING: You'll most probably loose ALL your data, and might break your phone. Please use with extreme caution!
The goal of this ROM is to provide full Treble-compatible hardware support, and nothing else.
This means that hardware which DON'T have Treble API won't be supported, like Essential's external camera.
No feature will be added. This will ease forward porting to new Android versions, which is the very goal of Project Treble
My hope is that other ROM developers will use this ROM as a basis to construct more advanced ROM.

How to know if your phone is supported:
- Does your OEM provides a stock Oreo ROM?
No ===> Your phone is not supported
- Run Treble Check on stock Oreo ROM. Does it say Treble is supported?
No ===> Your phone is not supported
If all answers are yes, then your phone MIGHT be supported.
Test it, and report the result!

Build script available at https://github.com/phhusson/treble_experimentations/blob/master/build.sh
Current status:
Over-all:
Xperia XZ1:
- Broken camera (because of Sony's DRM)
Huawei Mate 9 Pro and Honor 9:
- Fingerprint sensor should have "home" behaviour
- software keys should be disabled
Known end-user problems (WON'T BE FIXED in this ROM):
- No exfat

---

Known mess:
- A-only should use https://android-review.googlesource.com/q/hashtag:"non-ab-boot-gsi"+(status:open OR status:merged) instead of dm-verity hacks
- the dm-verity work-around is also needed on A/B, so other patches are missing, for some other reason
- On A/B devices, this system.img effectively transforms the device into a userdebug build. This means adb root works!
adb root should work on A-only later too, though it requires that the OEM includes https://android-review.googlesource.com/q/topic:move-adbd-to-system+(status:open+OR+status:merged)
This can probably be worked-around by moving adbd inside a /system/etc/init/xxx.rc
- ADB auth is totally disabled at the moment on A/B, this is bad, but useful for debugging.
- Huawei (for instance Mate 9) doesn't declare android.hardware.fingerprint. This ROM does it for them, but this need to be better implemented
- SuperSU and Magisk screws with SELinux policy. DO NOT USE SuperSU OR Magisk WITH THIS ROM

Great work guys, indeed revolutionary work, Congrats

That phone was released in 2013, so it's unlikely.

Support for Xiaomi Redmi Note 4 (mido), is it possible?

Following the project.
weldone @phhusson.

OnePlus said they won't support Treble, so no.
You can try to complain to them, since all they do is because for good PR.

Wonderful work you're doing here! Would you mind explaining what is the A/B only versions? What do those letters mean? Are there means of reverting back from your experimental build to stock Oreo?

A/B refers to the new partitioning system on the Pixel and Essential devices. It has one active slot and a backup slot for all parts of the system, so you'll have a boot_a and boot_b, system_a and system_b, and so on. Most devices still use a singular slot system, so unless you have a pixel or essential phone, you would flash the normal O build. Also, the steps on how to flashing back to stock are usually device specific, but you should be able to restore your stock O build by just reflashing the stock system.IMG from your device and wiping in fastboot.

Oh, thank you for explaining that to me! I have a Mate 9 and I seem to enjoy living on the bleeding edge, at the same time I'm dependent on WiFi tethering for my net. So may try it and see how it works at least. Would love to see if we get any opportunities to fiddle with the camera processing and GPS subsystems, as those are my hobbies.

Well A/B is the new partitioning scheme where all firmware partition exist twice, and the bootloader switches from one to the other when updating. This is also called seamless updates.
To revert back to stock... Well flash stock?

interesting project, I've a question..are there any chance to run this project on device like P8 Lite 2015 (Kirin620) and P8 Lite 2017 (kirin655) since both are arm64? and also System A/B must be enabled on that device? thanks in advance

Unless they are officially updated to Oreo and supports Treble (very unlikely), then no.

Only P8 Lite 2017 will get Android Oreo soon reported by many websites, but not sure if can handle Treble project.

I can try Port for Mido (Redmi Note 4/X)?
