phone not turning on

hi i was wondering if anybody could help me with my phone.
basically I got it trapped in a door and the back frame bent , so its like a curve now.
it was working perfectly fine even after this impact, but I took the screen off to try and bend the frame back a bit so the screen doesn't stay popping out.
now ive put everything back together and the phone wont turn on at all, no matter how long I hold the power button

so I tried plugging it in and it stays on connect to iTunes, then iTunes says phone is in recovery mode so I restored it as iTunes said to do that.
now when it finished, the exact same thing happens. it doesn't turn on, and the same happens when you plug it in says its in recovery mode.

can anyone help me, it seems like I may have damaged something while the phone was apart.

thanks
