I seem to damage my lightning cables (iPhone charging cords) easily. Does anyone have any good tips on extending their...

Have you tried turning the phone on in Safe Mode? If you open your phone up in Safe Mode and you are able to receive calls, then it is most likely a software problem. To open your phone in Safe Mode: (1) Turn the device off. (2) Press and hold the Power key past the model name screen appearing on the screen. (3) Release the Power key when "SAMSUNG" appears on the screen. (4) Press and hold the Volume Down key immediately after releasing the power key. (5) Continue to hold the Volume Down key until the device finishes restarting. (6) Release the Volume Down key when "Safe Mode" appears in the bottom left corner of the screen.

I’m not sure if I can change the prerequisite guides now that this one has been published, but we do have a motherboard replacement guide here. It has detailed instructions on removing the motherboard/logic board.

Thanks! I’ll see if I can add that in.

Is there a chance that the microphone was damaged when your screen was replaced? It is also possibly a software issue. Have you tried booting your phone in Safe Mode (directions are above, under “The Speakers Don’t Play Sound” in “Software Glitches”). Try calling someone while your phone is in Safe Mode and see if you notice the same results.

We might also have called the logic board the mother board, which you do not need to remove as long as you detach all of the cables.

Oh, I think I get what y’all are pointing out.

1) We called the logic board the charging port board.

2) We did disconnect the two cables (the blue and white ones, right?) in the step above, as seen by the upper red rectangle. (Look at step #13)

3) I’m having trouble finding which screw we missed. Could you identify it a little better so I can fix the picture? (Look at step #12)

Hey, this picture would benefit from some marking up; the black panel is a little hard to see. I’d do it myself but I don’t think I can access the original photo.

Could you point out to me where the logic board is? It’s possible we called it something else.

Hi Kara! If I remember correctly, we didn’t need to remove the battery. However, it’s been over a year, so I could definitely be wrong.

Hi Elliot! If you replace your charging port, you will need to replace the back cover, but the screen should remain intact. It is very difficult to remove the back cover without breaking it (unless you have access to a heat gun), so if you’re thinking about replacing your charging port, you may want to get a new back cover ready beforehand. Good luck and Happy Fixing!

What should I disconnect the wires with?
