Apple boot loop after screen replacement

I replaced a screen for iphone 5s. Screen worked fine before I put screws in. After tightening in the screws its in a boot loop. The screen stays black with white apple logo, then restarts. Tried DFU restore and it gives me error code 9. Any ideas?

Hmmm...

The fact that it worked just before you put in the screws makes me wonder if you didn't accidentally put in the screws in the wrong place. I would take the screws out (for the screen bracket) and check them with a digital caliper to be certain they were not screwed in the wrong holes. You could have Long-Screw Damage

Austin's suggestions are good too so I would definitely try them.

try a different battery. if that doesnt help, try connecting the screen without the prox flex. a damaged prox flex can cause all sorts of weird boot issues.
