Bug description:
  On Meizu MX4 upgrade from OTA-9.1 to OTA-10 fails.
  Upgrade downloads normally, phone restarts and starts system upgrade and after a while it freezes with strange icon (small microchip with red sign on it)

  When you turn off the phone and start it again it still presents itself as OTA-9.1 and again it founds and offer upgrade.
  Anyway some changes from OTA-10 seems to be applied, because I can see design changes, copy function in web browser etc.

  It's reproducible on my phone any time I try to upgrade. If I can help
  with output of some log, or anything else, please let me know.

  Well described here by Lars Kristian Wichmann Hansen:
