Install the update without an SD card
The SD card on your phone isn’t really a necessity when installing updates, and has been known to cause bugs and errors in more than one build of the Windows 10 Mobile operating system. To install this update, do the following:
- Soft reset the phone. Do this by holding the Volume down and Power buttons at the same time, until you feel a vibration. That shouldn’t take longer than 10 to 15 seconds. Note that you shouldn’t touch the device screen at any time.
- When your device turns on, go to Settings, then System and finally
- Tap the SD Card, scroll down and tap Remove. If you get a prompt that your files won’t be available until you plug the card back in, tap Yes, I’m sure. You can now physically remove the SD card.
- Go to the Settings menu again, and open Update & Security.
- Open Phone update, and tap Check for updates. Your phone should now be able to download the 0.14926.1000 update.
