iphone 7 wont boot past logo - GSM-Forum

mikeswan · 12-08-2017, 16:41

so I have an iphone 7 that was smashed really badly.

I put a new screen on it and all seemed to be working. a month later he brought the phone back saying that it was taking a long time to boot up and that the screen was freezing.
My first thought was the screen had gone bad or he had dropped it again. So I swapped out the screen and the phone still acted the same. like 20 minutes to boot up.
while troubleshooting the issue i unhooked the front camera flex and that seemed to be better.. It would still take a few minutes to boot though. shortly after that the screen froze and it needed a reboot.
So i thought maybe a sofTware issue. I noticed that the phone needed an update so i installed the update through itunes. this seemed to work except it would not complete the file restoration. So I did a full factory restore. This seemed to finish without any issues until the final reboot. then it just hangs on the apple logo again. it seems to have gotten worse as the days go by. now it will not boot up at all.

any ideas what might be causing it?

The best option, when faced with this issue, is to put your iPhone 7 into recovery mode.Recovery mode is where something has gone wrong with the software on your iPhone, so it can’t be used. To be safe, you must, therefore, restore your device.

If you are facing this issue, please try the following steps to get it resolved. You need a computer running the latest iTunes in order to resolve this problem.

1 Using the Apple cable, Plug your iPhone into the computer running iTunes
2 Perform a forced restart. Press and Hold Power and Volume Down buttons for 10 seconds or so or for iPhone 8 press the volume up, volume down, and then power
3 After 10 seconds, you can release the Power button but continue pressing the Volume down button until you see the message from iTunes that says it has found the device in recovery mode
4 Click on Restore to get the iPhone restored
5 The device shows a black screen and eventually get restored
The important element here is that you need to follow Step 2 and Step 3 correctly. If you see the message “Connect to iTunes” on your iPhone, that would mean that your device is not in recovery mode. You may have to try the steps again.
Conclusions

Several users have noted that they can get around recovery errors by simply removing the SIM Card of the device while trying to restore the iPhone. If you run into error messages during the restore/recovery process and you are using the right USB cable etc, you may want to explore removing the SIM card out of your iPhone and trying it.
Once the device has restored, you put back the SIM Card back into your iPhone.

Good luck to you--Vip Fix Shop Team

It is your auido ic guaranteed. You need to remove, reball and add 4 jumpers. I do these all day long

I have the same issue in my workshop, forunately I was able to resolve it and I've recorded a solution for forum members:

First check home button (try with another original button) if stiil booting slow then reball audio ic.

Baladeva · 03-26-2018, 12:40

Try to lower the heat not to damage logic board components, just a tip.

gayansuranga · 03-26-2018, 12:52

If you had some issues with the audio when it was in the working condition. It must be the audio Ic. 338S00105. In fact its a common issue in 7 7+
