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.

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

OTA update packages to download (just in case anyone needs):

You want to unlock bootloader now and get twrp? Go on here:https://zukfans.eu/community/threads/howto-unlock-bootloader-and-get-twrp-on-zuk-z2-pro.7707/

You want to get ZUI 3.5.259 having gapps etc.? Go on here: https://zukfans.eu/community/threads/do-you-want-to-update-to-oreo-read-this-first.7848/


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.

If you encounter problems with updating the single OTAs:

Please try using directly this OTA version to 3.5.259: https://androidfilehost.com/?fid=890129502657584731

It is a full version. So it should work on top of any other ZUI version with lower version number.

I tested it just once so it would be nice if someone could verifiy my test as well.

Dont forget: Put the file to root directory, rename it to update.zip.

Please send me a PM once it worked or you encountered problems with this way.

thx, enjoy mates :)
