Can I still use my iphone 5 after being erased thru find my iphone?

Ok so I have no idea how my settings got deleted. So I erased my iphone thru find my iphone app. After that I've been waiting for around 9-hours and it has a black screen with a circle around it. Will I be able to use my iphone again and how long will this take?

You need to sync it to iTunes.

If that does not work, you will need to DFU your phone and then sync it to iTunes.

Once synced you will need to restore to a backup or do a fresh install.

If you need to DFU, it's extremely easy, search iPhone DFU on youtube.

What? Are you serious?
