iPhone 11 Pro completely dead after cleaning earpiece and reassembling
I have an iphone 11 pro whose earpiece got wet. This caused it to boot loop, and then when trying to restore using itunes, it caused error code 4013.
I read that the earpiece is often the cause of this issue. So I opened the phone, took off the plate covering the earpiece cable (6 screws). I then unhooked the earpiece cable and was able to bring the phone back to life, but without earpiece functionality.
Note that while working on the phone, I never unhooked the battery cable, which I now realize I should have done.
I then proceeded to remove the earpiece assembly completely from the front screen and clean it. Then after reattaching it to the front screen and plugging in the cable the earpiece functionality was working too. I then removed the earpiece assembly and reattached it one more time to seat it better, and finally I plugged the earpiece cable back into the motherboard, and put the covering plate with the 6 screws back on.
However when I tried to turn the phone on after all this it showed no signs of life. Display was completely black and no response. A complete brick.
I tried several things after this, including hard resets, charging, unplugging the earpiece cable, removing the battery cable temporarily, plugging phone into a computer with itunes. But I get no response at all. Nothing on the screen, no vibrations, no heating up, and itunes does not recognize that any device is plugged in. I even completely unhooked all the screen cables and plugged it into itunes, but still no signs of life. This indicates to me that the problem is not on the screen or earpiece. The phone is now a complete brick.
I’m guessing that what happened is one of the following:
1) Since I left the battery cable plugged in while I was working on the phone, I shorted out something on the motherboard and fried it, so it won’t do anything.
2) When I put the screws on the cover plate back in, I screwed one in too far, and destroyed a motherboard trace.
Anyone have any ideas of what might have happened and what I can try to bring the phone back to life. Strange that there were no signs of life at all after having it completely functional temporarily. And the only cable I unplugged during this time was the earpiece cable, so I couldn’t have re-plugged any other cables incorrectly.
I am posting some pictures I took after taking the phone apart again to try and bring it back to life. Just in case anyone can spot something obviously wrong.
This is just the motherboard area with the plate removed:
This is the entire base of the phone with the screen removed and battery cable unplugged:
This is the entire phone after reassembly with the cover plate attached too:
Questa è una buona domanda?
