Ear piece issue / unlimited boot / front camera flex
Hi, I'm here to address this issue and see if I can have some sort of explanation as well.
So I have now seen this problem 2 times.
Where after a repair is done, something is knocked off or something was done wrong.
But basically once the repair is complete your iPhone won't go pass the Apple logo.
Common issue I know. But keep reading.
The basics were done
Replaced the top flex cable
Used an original screen
Home button was good.
Even used the original screen from the first repair.
So here's a fix to get ACCESS to the home screen.
It took me forever to figure it out but here's my Conclusión
Put the iPhone in recovery mode
DFU or iTunes mode
You're gonna factory restart the phone.
So I did this twice and the pattern was the same
Once the phone is restarted it stays stuck on the logo
if you disconnect the screen and the battery and reconnect it after the restart is done,
It'll go to the set up screen.
It's very odd and I don't know why it does this.
You'll notice it's going to be very glitchy.
Almost like you can't do anything.
My first thought is that it was the audio IC
But that is incorrect (keep reading)
So I tried different things like unplugging the flex connector.
But once I shut the phone off it never went to the set up screen again.
It's like it gives you access that one time.
So I factory restarted the phone again.
And same process with unplugging the device and plugging the screen back in
Same thing. It sets up the first time but that's it.
So I tried to restart it one last time
And the third time was the best one.
From there I could actually turn the phone off and on as much as I wanted although sometimes it took up to an hour to boot up.
I noticed a pattern in the flex cables on the top.
Because once it boot up and seemed perfectly functional. There was always a problem with the flex cables on top.
Either the camera
Or the proximity sensor
More commonly the ear piece wouldn't work
I couldn't even talk on the phone, the other person can't hear me and I couldn't even put It on speaker.
Its an issue alright.
I tried like 5 different flex cables from different companies
It was always something.
So on the first phone it's working good, I can turn it off and on as much as I want, the no phone calls is the only issue now.
The second phone I worked on that had the same issue.
Same thing someone replaced a screen and then it didn't want to boot pass the logo anymore
This time I did the same thing
Restarted through iTunes although it always came glitchy.
Tried different flex cables.
But I noticed when you take off the flex cable
And restart through iTunes without it being connected, once it finishes restarting, it'll be stuck on the logo of course
But if you unplug the battery and replug the top flex, it'll boot up and work fine (except the phone call problem popped up too)
So my question is what is this issue?
I tried contacting a friend that works at an Apple Store and does repairs and he commented saying they just replaced the whole board.
Seems idk, too much, i want a specific solution.
Any one seen a video about this or know what this is???
It's very frustrating please spread and help me find a solution
Is this a good question?
