Windows 10 Mobile Installation issues & workarounds:

  • Installation seems stuck at 0% for hours. What you can do is
    • Plug-in your device as in some devices there is a “Battery Saver” bug that stops download and installation of the build.
    • Try a soft reset and try downloading and installing the build again.
  • In case you see spinning gears for longer duration during update process, you should wait if gears are spinning. If gears are stuck then only issue arises. Try soft reset first and if it doesn’t work try hard reset. You can follow our reset tutorial.
  • Many times you see a blank screen once the installation is over. You should wait for 15-20 minutes as migration may be going on below that Blank Screen. This bug affects many devices and is always better to let the device do its own thing or else you may face issues.
