iOS refuses to update on 2 of my devices....

[Nothingfaced]

*on my iPad mini, the update downloads, restarts, gets to the "Apple" logo with the running bar, and then randomly restarts and goes back to iOS7. It refuses to update. It's done this almost 10 times.

*on my iPod, the update won't even get to the Apple bar. it says "Unable to install update".

Frustrating, and disappointing. Is this an issue with Apple servers, or are my devices toast?

Your devices are not toast. But that is very odd.

Have you tried using iTunes to do a tethered update, plug in, press the update button?

edit: worst case:
Backup to iCloud
Google DFU Restore, load iOS8
Restore from iCloud.
