iOS 8.4 update frozen/not working
Hello there, everyone. I have an iPad 4th Gen and I tried to update it to iOS 8.4 - It starts up to the white loading screen, and the bar gets half way and then it crashes and starts all over again. I held the power/home button to reset, then it brings me to a "slide to update" screen, which I slide and enter my passcode, and then it repeats the above.
Any help would be appreciated - I tried the support chat but it keeps wanting a serial number, which I cannot access, as my iPad is about as useful as a brick at the moment.
