[OTA] Collection / HowTo get from ZUI 1.9 to latest ZUI for Z2 Pro

[weimerd]

Hi mates,

------------------------------------------------------
for the ones who only search for OTA update packages and don't need instructions see here: https://androidfilehost.com/?w=files&flid=251521
------------------------------------------------------

Finally you made it: Messed up your phone or want to make sure your phone is set back to ZUI original.

That's what I did as well several times while flashing and testing around several roms.
To avoid problems with Lenovo OTA servers I made up this thread to safely update to latest ZUI using OTA updates without needing them to download from Lenovo OTA server.

First step: Flashing ZUI 1.9 with QFIL.

Download Qpst/Qfil 2.7.472 here: https://www.androidfilehost.com/?fid=962187416754462223 and install it.

Download ZUI 1.9.104 here: https://androidfilehost.com/?fid=962187416754462214

Extract ZUI 1.9.104 to C:\ZUK\ and flash it with QFIL. See here for more detailed instructions: https://forum.xda-developers.com/zuk-z2-pro/how-to/howto-flash-stock-zui-rom-zuk-z2-pro-t3928699


Second step: Flashing full OTA update to 3.5.259ST with System Updater.

You successfully booted ZUI 1.9. To see it from Chinese into English follow instruction here: https://www.youtube.com/watch?v=jFM_a3-wYD8

Download Full Update ZUI 3.5.259ST: https://androidfilehost.com/?fid=890129502657584731

Connect your phone to computer.

Rename the downloaded zip file to "update.zip" and copy it to internal storage root directory of your phone.

Start System Updater App, tap on the three dots on upper right corner and choose reboot to recovery.

Your phone will now reboot to recovery asking you if it shall update the package. Accept it and let it be installed.

After installing your phone will boot up again and your ZUI version will be upgraded from 1.9 to 3.5.259.

Congratulations, your system is up to date now.

You want to unlock bootloader now and get twrp? Go on here: https://forum.xda-developers.com/zuk-z2-pro/how-to/howto-unlock-bootloader-twrp-zuk-z2-pro-t3928705

------------------------------------------------------

I will update this post with new OTA packages once they are out.


Enjoy mates



PS: Yes, I know: latest ZUI 3.5.259ST update is a full package and not the real OTA update as this is not released yet. Anyhow it works in the same way and will not clean your system or anything. It will simply work as an update.

--> I added this here as zukfans eu may close soon and I want to avoid instructions get lost.

Nice Contribution!!, I `ve used the links you provided and dowloaded the 3.5 ZUI Version... And from there I continued with automatic OTA updates from the phone, up to 4.0.247 ST... Everything working great!, It reduced battery consumption enormously! and evrything works better (I bougth the phone with a preinstaled "Multilanguage" non official ROM, it was working awfully, and got me stuck on Android 6.0).

Thanks again!

Hello,
I've also updated to 4.0.247 ST, which runs Android 8.0. Everything seems to be fine, but I cannot get netflix to work. Play store says my device is not compatible. The apk offered by netflix on their website supports up to Android 7, so it does not work either.

I've read that the netflix app requires devices to be play protect certified in Android 8 and above, which this device is not. Does anyone know a way to circumvent this issue?

Thanks and best regards
