Stuck in the iOS 8.0.1 Failed to Install Twilight Zone?

All of my pre-iPhone 6 iOS devices (iPhone 5s and 4s) were updated to iOS 8.0.1 without problems. Apple, however, did pull the platform update during my iPad Mini-Retina installation. It left a red herring message saying to the effect the update could not be completed because the Internet was not connected.

If you are experiencing the same problem which I'd encountered with the iPad Mini iOS 8.0.1 install process, don't mess with your internet router and settings. Most important, don't panic and go restoring your iOS 8.0 via iTunes. The prior updated iOS 8.0 is still working on the installed device.

To rid the "stuck" iOS 8.0.1 installation file, do these steps instead.

On your iOS 8.0.1 stuck-during-install devices, do the following:

Settings > General > Usage > Manage Storage >select the first app on the top which is the iOS 8.0.1 update file > Delete.

If you have already updated to 8.0.1 on your iPhone 6 which had messed up your cellular calling services and Touch ID, do a search on Google for help. I recommend the affected user go directly to the Apple Knowledge Base for a temporary fix at:
