Phone wont fully boot after fall

Phone took a fall and was stuck in a reboot loop after being plugged in, I opened up the phone and saw the battery was disconnected so I reconnected it thinking it was a simple fix. Instead the phone woukdn’t go past the apple logo. Ive disconnected all of the pieces that I know of to see if it would boot up without them to see if any of them were the issue. The phone already doesnt have a home button due to it going into a boot loop when the home button is connected. Is it worth trying to switch out screen& battery?? Not sure the problem

Also the phone will stay on that screen when unplugged for hours so I feel like that rules out the battery issue

Answer this question I have this problem too

Is this a good question?

Have you tried to update/restore the phone by putting it in dfu mode and connect to iTunes or 3U Tools?

Otherwise I think it is a fault in logic board.

  • Try using a USB Ammeter, and check if the iPhone draws more than 0.5A.
  • Try putting it to DFU Mode or Recovery mode, then connect it to a computer with 3uTools or iTunes.
  • Try turning on the phone then connect it to a computer with 3uTools and check if it sees the iPhone.

If none of the above works then:

  • A plug or connector might not be plugged or seated properly.
  • The Lightning Connector Assembly might got damaged.
  • The logic board might got damaged

From my experience, a connector might have been dislodged or unplugged when it was dropped. Try checking if a connector is completely plugged by lightly pulling the plug (as if your trying to disconnect it) using a pry tool or fingernails. If the plug easily disconnects, then it was not plugged properly. Also try looking at the connector if it is completely flat and you don’t see any contacts or gold traces.

I also forgot to mention that the connector might also be dirty, causing poor connection.

I tried using the 3u Tools, it did locate the phone but it said error at 20% into using flash. The phone already had loads of issues before this fall. The home button is gone, the home button ribbon from the screen was ripped, and the wifi didn't work (guessing a logic board issue), so i could only use data. Even with all of those issues the phone worked, but doesn't after this last fall. Im gunna give the screen replacement a go just to see if it could be the missing /ripped ribbon.
