You can't install 14.8 anymore now that iOS 15 is avaliable.


Go to Settings - General - iPhone Storage - check here for an iOS 14.8 update file. Delete the file. 

Restart and see if the iOS 15 update is now available.

To update all of these requirements must be met:

  • You must be connected to a Wi-Fi network (and not a personal hotspot) unless it is an iPhone 12 series with an active 5G network connection
  • The phone must be charged to at least 50%, and preferably plugged in so it stays above 50% during the update
  • The phone must not be in Low Power Mode
  • The phone must not be connected through VPN
  • The phone cannot be in Airplane mode
