Hello there this is my first time using a fourm page, I have 3 years of experience fixing iphones, Ipads Etc and all of them come out to a great success, But now i decided to step it up a bit to fix my Besel. My phone fell out of my pocket into the door jam while i was closing my driver door and ended up bending the besel and damaging the LCD on the screen the glass was perfectly fine. (The iphone bent on the Upper left corner right above the battery where the volume rocker &power button flex cables connect.) I removed the battery carefully and the logic board and bent the phone as straight as it can be with my eye haha. I put everything back together with a brand new Apple Certified Screen with New LCD & digitizer and the phone is unresponsive… Like it wont power on or vibrate when it boots up like it shows me nothing! I left it connected overnight and still nothing just Dead/Dark I took the phone apart carefully and made sure ALL my connections where good and they were. I put the phone back together again and nothing once again.. this is like the first time this has happend to me i’m thinking due to the bend my logic board may of had damaged itself while i was removing the screws from that corner i dont know. My mind is everywhere right now and yes i even tried holding down the power button and home button for 15-20 seconds and still nothing. If this has happend to anyone please help me out.

Did you bend the battery? Try to check the voltage. It should be above 3.7 volts, if not replace it.
