My iPhone 5 is stuck in recovery mode after downloading something from Cydia?

I downloadedsomething from Cydia, and it must have been bad because when i pressed restard springboard it got stuck at the apple logo.
So, I tried completely recovering my phone in iTunes and didn't work, then I tried using the umbrella program, that didn't work either. Also, when I plug it in my computer it will vibrate every 5 seconds or so. It's turning on now, but it keeps getting stuck booting up.
So, is my phone pretty much broken now? Should I just get a knew one? It was something in Cydia that I downloaded to make this happen. Anything I can do to delte that? I also never had my phone backed up.

Your iPhones done for I did it to my iPod and I couldn't get it back I tried EVERYTHING AND I MEAN EVERYTHING

If your in PA, email me i can fix it or exchange it for a new one.
