Why is my iPhone 5 stuck in this loop?

[iMore Question]

Froze up last night and then came back up on its own, then about an hour later started this loop, been doing this for about 12 hours. {\rtf1\ansi\ansicpg1252

I do not know why 'your' iPhone 5 is in a boot loop. Having said that, you should be able to put your device in recovery mode and get it back to working properly in no time.
