And the other important point is taiwan vision only suit ota updatre from Taiwan.
If you're in othet county, maybe ota will fail.

Hi,
Try to use the system restore and format your SD card, make sure your phone is not rooted.
It should be good.
PS: I'm currently use the taiwanese version, and living in europe, I have no problem about OTA. So doesn't matter where you live, you should update your system without problem.
Regard.
