iPhone 5S Wont show signs of life after camera replacement

So I went on to replace the front camera on my iPhone and once I finished I go and I put everything back on and the phone refuses to turn on I switch the mute/sound switch up/down and I get no vibrations. So I go back into the phone and start fidgeting with it and remove battery and plug it back and plug in the phone to power and to computer and nothing works, instead the phone gets really hot, so please help, it would be greatly appreciated if I can get this to work ;(.
