iPhone 6: Touch ID not working after screen replacement?

Sun, 01 Feb 2026 02:32:32 -0700

I have made a screen replacement on my iPhone 6. Now the touch ID does not work any more. I have read that if the home button flex cable is damaged, this can occur. Is that really so? The button itself is working just fine.

I know for a fact that the home button can not be replaced because then touch id will not work, plus you can never upgrade the phone again without getting a error 53. Can you confirm this?

So my last question. Can I replace the home button flex cable or is that also coded to the chip or home button touch id?

iPhone 4: iPhone 4 is working but screen is black?

Sun, 08 Jun 2025 09:30:24 -0700

Yesterday I dropped my phone, and it was working fine when I picked it up to check it, but a few minutes later the screen went black. I know it was still working, because I was still receiving phone calls, texts, and mail. I even took a picture with it.

I've tried holding the home and lock button. I also tried holding the lock button while constantly pressing the home button, but I think the problem with this is that my home button barely worked before the drop. I've tried to reset it and put it in DFU mode, but nothing is working. :( Note that I can't take it to the shop because it's jailbroken.

iPhone 5s: Restore error 9 and 14 after fixing iPhone screen. What to do?

Tue, 20 Aug 2019 08:55:42 -0700

My iPhone 5s screen cracked, so I replaced the screen. When I replaced the screen the battery wouldn't charge, so I turned the phone off. When I turned it back on again, it was stuck on the Apple logo. I then restored it—but in the middle of the restore, the phone stopped working. Now the phone is stuck on the "connect to iTunes" error and when I try to restore it, I get mostly error 9. I tried all my computers (2 Macs, and a PC) and all the USB hubs that they have. What do I do? Thanks.

Since the screen was a third party, all I did was was restore the iPhone with the screen disconnected. Once it shows that the restore finished on my computer, I reconnected the screen and finished the setup.

iPhone 6 Plus: iPhone isn't recognized by computer as a device?

Mon, 01 Dec 2025 11:43:41 -0700

My iPhone 6 plus will not be recognized as a device in my PC. I cannot sync to anything to add music or any kind of iTunes media that isn't instantly downloaded to my iPhone.

My phone will charge but my PC won't give a prompt saying a device is plugged in. This is not an issue with drivers because I have troubleshooted already and I have tried a different cord and even a different PC.

Any suggestions would be helpful, cheers.

iPhone 4S: Black Screen and lock button not working... What should I do?

Mon, 05 Apr 2021 09:38:14 -0700

Hello!

Today my iPhone's screen just turned off and doesn't seem to work. I believe it's a software problem, so I thought the best idea would be to force a reboot (you know, holding the lock and home buttons at the same time). However, I don't have a lock button, since it has been broken for some months now.

What can I do? Any tips on how to drain the battery of the iPhone as quickly as possible? I have started to send Messages from my Mac because that way it will be forced to emit the notification, but this could take hours.

Thanks for your help!

iPhone 6: Ear speaker low sound when making calls

Fri, 26 Sep 2025 10:38:43 -0700

I have a customer that brought his iPhone 6 saying his ear speaker volume was very low and he could barely hear what the other person was saying even in a quiet room. I did some tests and when I use the recorder to record my voice and listen to it through the ear speaker the sound is crisp and clear, I hear very well.

When I try to make a phone call, the sound is very low, even with the volume at maximum. I tried switching SIM card and even replacing the ear speaker and flex cable.

What could be causing this problem ?

iPhone 4: Why aren't my volume buttons or ringer working?

Fri, 09 May 2025 09:41:49 -0700

For two weeks now, my side volume buttons haven't worked. When I try to change the volume, the little speaker picture doesn't even show up. I can't hear any of my incoming calls or text messages. But if I play music on my iPhone, I can hear it. So my speaker does work. I can't find any information about what I have to do. My phone is updated to iOS 5.1.1, and it isn't jailbroken.

I work on iPhones often. With this one, I opened it and replaced the screen. Before I closed it up, I tried to turn it on, but it would not turn on. I also tried to plug it in, and it repeatedly made the charging sound.

iPhone 4: When making calls, the other party can't hear me.

Fri, 01 Jul 2022 17:31:47 -0700

When I make a call through the handset, the other party can't hear me—but when I turn on speaker phone, they can hear me just fine. I can hear them, and the ringer works just fine.

Any thoughts?

Oh, and also, I can hear myself in the handset in an echo.

iPhone 4: iPhone4 won't restore and shows Error 21

Wed, 12 Oct 2022 03:43:11 -0700

My phone won't turn on, but shows the Apple logo when I plug it in (either to the wall charger or the computer). Then, it goes to the Connect to iTunes screen and when I connect it to iTunes it tells me that I need to restore the phone. It will get all the way to "preparing iPhone for restore" then will say, "The iPhone could not be restored. An unknown error occurred (21)." I tried to disable my computer security, but it did the same thing. Does anyone know what else I could do to fix it? Please help!

iPhone 6: GPS & Bluetooth work sporadically.

Sat, 10 Apr 2021 16:46:46 -0700

I have a 128GB iPhone 6, just out of warranty. Two days ago, the GPS signal and Bluetooth connections weakened. They still work, but GPS shows a cone of confusion about 100 feet wide, making navigation and fitness tracking impossible. Bluetooth works within about 3 feet, but any more than that, it cuts out.

My phone is 25 days out of warranty, and Apple and AT&T were not helpful. Anyone have an idea of what the issue could be? WiFi works fine, as do calls, and the phone in is near-mint condition. Any ideas of what the problem could be?

Thanks!

Again my phone only charges when its off but never when its on.
