Cannot restore with iTunes after replacing battery

This is what happened.

I replaced my iPhone 5S's battery, but I lost the screws for the metal battery connector bracket(is this part important at all?). I thought it was unimportant so i just put the entire iPhone together anyway.

Turned the phone on, everything worked as per normal. For some reason I wanted to restore the phone. Plugged into my PC and clicked restore on iTunes. Error 1 came up, then my phone got stuck in recovery mode. Tried repeatedly, kept failing.

What should I do? Below are the methods I've tried.

Put into DFU: Didn't work, still Error 1.

Change USB ports: Didn't work as well.

Use TinyUmbrella: "Fix Recovery" didn't work.

WHAT SHOULD I DO? ):
