I'm using a 64GB Meizu Pro 5. I had it running with OTA-12 without any problems. Because I did not flash the Pro 5 boot loader I had to upgrade the OTA manually as described in How to update meizu pro 5

After restarting the device the applications work but whenever I go into any System Settings window it stays completely blank.

I wiped the cache and data (making a factory reset in TWRP) but the problem persists.

When I flash ubuntu-*.tar.xz I get the following message: tar: can't remove old file system/usr/share/doc/libtelepathy-qt5-0: Is a directory

Here the log after opening the system settings:

Has anyone upgraded from OTA-12 to OTA-13 successfully? What do I need to change in order to make the System Settings window appear?

Thanks!

Can you post a screenshot or two of what's wrong? – dobey Sep 27 '16 at 16:49
    
Unfortunately a screenshot wouldn't show much. The whole settings screen is just white. No icons, no text. No matter how I access it. E.g. when I open the top notification area and click on About this device, mobile settings, etc. – torusJKL Sep 27 '16 at 17:27
    
It'd really help if you could show us your /home/phablet/.cache/upstart/application-legacy-ubuntu-syste‌​m-settings-.log — Thanks! – Jonas G. Drange Sep 28 '16 at 10:35
    
I added the log to the original question above. – torusJKL Sep 28 '16 at 13:38

The problem was that the folder /usr/share/ubuntu/settings/system/qml-plugins/SystemSettings/ListItems/ and all its files was missing.

I was able to fix this by doing

  1. flash the OTA-13 delta files
  2. reboot into the system
  3. flash the full OTA-13 files

(flashing the full OTA-13 directly over OTA-12 would make make the phone fail at boot time)
