Basically I updated my iPhone to ios 11 beta 2 to test it out and I decided to go back to 10 today. I downloaded the IPSW file for it and tried to restore it via iTunes. After some time it gave me an error and just doesn't let me update. It says it updated, then it moves me to a screen where it tells me to update or restore and puts me back into DFU mode. (Same thing happens if i click update or restore).
This is what I get when i try any of the options
