Hello everyone!

So... since 2018/03/31 we have a treble compatible vendor image without any problems so far.

To test a Generic System Image (GSI), you need the following:

  1. Flash the last TWRP recovery build: https://twrp.me/zuk/zukz2row.html
  2. Flash a recent baseband. As a rule, the last one is always the best: https://forum.xda-developers.com/zuk-z2-pro/development/radio-modem-basebands-zuk-z2-pro-t3715835
  3. Flash a boot.img image with support for early mounting of the system and vendor partitions: https://github.com/cosmedd/android_kernel_zuk_msm8996/releases
  4. Flash the vendor image for our device (z2_row): https://github.com/zuk-devs/android_vendor_zuk/releases
  5. Flash the GSI of your choice: https://forum.xda-developers.com/project-treble (Note: ours is an A-only device)

Keep in mind that, as the name implies, generic images will have fewer functions than dedicated ROMs, since they are designed to support as many devices as possible. On the other hand, they are lighter and closer to pure AOSP.

But the basic functions like camera, audio, radio, gps, hardware acceleration, fingerprint, gyroscope, etc... should work out of the box.

If you still do not understand what this means and simplifying a lot... think of boot + baseband + vendor images as the drivers for our device and the Generic System Images (GSI) as the operating system.

In theory, this vendor image will also allows us to get Android 9, 10, 11, etc... with few or no changes. :eek:

Now you no longer depend on the developers of Z2 Pro, as anyone from any device can build a GSI. This means more people who can provide an updated system for our device.

Even if you are not going to use GSI now, I still recommend that you download it and keep it in a safe place in case you need it someday.

Thanks to: DD3Boh, davidevinavil and the xiaomi/msm8996 devs, you make life easier for the rest of us! ;)

thank you very much for your work, this is very good news. I have to assess if it's worth losing the customization of the current custom ROM

I don't use two sim cards . The personalization is very low . I think you should use xposed to increase the personalization . Unfortunately Los 15.1 is without gapps .
Edit
install los15.1 , factory reset / install (optional for root ) addonsu arm64 14.1 from extras Los download ( there are not exist for 15.1 yet ) / install pico open gaps / factory reset / restart . Now it seems be good .

Screenshot LOS 15.1
Su is working but without any manager . You can only acrivate or deactivate it . There is lack of popup window with permission . ( allow , prompt , deny ) . For me is good but I think if you want u-touch and more customization better solution is useing Aex , rr or cosmic or waiting for cosme los 15.1 ( hope ) .

after clean flash I get android.phone crashes permanently with RR version.

No Gapps possible.

No root possible.

When doing dirty flash over latest official RR only gapps are crashing but system is somehow working.

When trying to flash gapps only pico gapps are possible to flash.

In summary:
It is a test version only yet. I guess vendor image is not perfect until now.

Gapps issue and Root issue is a treble general problem I think. Not connected to our device but treble connected. Anyway a solution is needed before it can be used for normal users.

I will do more investigations and tests in next days.

No any problems to install RR or Los 15.1 or AOSP with pico gapps . These ROMs are the same . Only slightly differences .
Install
2018.03.11 twrp
Boot_with_permissive_selinux.IMG
Vendor.IMG
RR or LOS 15.1 or AOSP phh-treble for a-only
Open gapps
Restart to system
For root install moded Magisk
https://forum.xda-developers.com/le...nt/rom-aospextended-rom-v5-0-t3683254/page851
There is version of AOSP system with inbuilt gapps and Su as well . Only what you have to do is install phh's superuser app
https://play.google.com/store/apps/details?id=me.phh.superuser
Edit
If you have error 70 during installation of micro gapps you have to resize system partition .
Reboot to twrp
Wipe/ Advanced wipe/ system/ repair or change file system/ resize file system
than swipe to confirme it . Do it twice because of error for first time .

    Good work, Zuk-devs :D


    I've flashed LineageOS and everything seems fine but now I can´t boot to EDL mode in order to flash with QFIL.
    Everytime I try to reboot to EDL mode, it boots normally. I tried to reboot with fastboot-edl without success.
    What should I do?

    Through Fastboot :
    Code:
    fastboot -i 0x2b4c oem reboot-edl

    Through TWRP > Terminal
    Code:
    reboot edl


    And here are some Screenshots from Last nights build of PhhAOSP Treble with GApps and SU inbuilt.
