Chosen Solution
My front camera isn’t working so I decided to check if its connected properly. Opened up the phone undo the screws put it back together and at the bottom left plate, the screw wasn’t going in. So I ignored it and leave the screw out. Put my screen back to the phone and it took me to a gray screen. Turned it off and had 2 vibrates. Tried to turn it back on but no response. Opened up the phone, undo all the screws and now I noticed this bottom left screw holder came out? Is there anything I can do to get it turn on again? I really hope theres a way. I tried holding home and power button for more than 30 seconds and nothing happening. Thanks
Either screen is busted or you may have blown the backlight filter (or more, other components that are part of the backlight circuit). Backlight filter usually goes bad when you unplug / plug in the screen with the battery still connected. You should be able to see the apple logo when you shine a flashlight to the screen and turn on the phone. Hopefully you do not have long screw damage on the bottom right screw hole on the logic board, that could also be related to the issue of the phone having no display.
Try unplugging the battery and plugging it back in. If it still does not power on try connecting to a charger with a usb cable.
Well first of all. You should check whether your phone reads to the computer to check if it is on that the logic board is not broken. Otherwise that check the connections. Troubleshoot and plugs and every time you do that unplug the phone and hold the power button and see if there is any response (like the backlight turning on or something). I have an bad lcd on my phone and whenever i open it and i run into the same problems. ALSO THIS IS IMPORTANT make sure there is no debris in the connections because this can mess things up.
You long screwed it. You put the long screw where the short screw goes and damaged the traces underneath as a result. LSD is on the expensive side of motherboard repair. You can send it to iPad rehab for repair if data is important.
