iPhone 5c: iPhone 5c Black Screen After Replacement?

Wed, 27 Feb 2019 04:44:27 -0700

I just finished replacing an iphone 5c screen, and checked to see if it would power on before I put the screen back fully into place. The apple logo came up and the phone powered on normally, so I shut it off and put the screen fully into place. However, the backlight seems to come on but the screen remains black with no apple logo. It still responds to charge still and vibrates but the lcd remains black. The connectors look normal and do not appear damaged in any way. I have tried hard resets and taken the phone apart several times with no avail. I have also tried other screens which produce the same result but work in other phones. I fear this may be a short in the logic board, and if it is such, is there any fix besides completely replacing the logic board?

iPhone 6: Touch ID fails to setup after disassembling iPhones with iOS 10.0.2

Fri, 26 Jan 2018 06:33:58 -0700

Hello, I was disassembling several iPhones (my included and an iPhone of a friend) both are iPhones 6 with 128GB. I replaced twice the display of the iPhone 6 of my friend, and everytime it worked properly. Same was done with my iPhone. Then today I had to open both iPhones. And after assembling them again, the Apple TouchID sensor (which are original and not swapped) were not functioning anymore. Both iPhones tell me "Failed Unable to Complete Touch ID Setup", I already did all the tricks. Reset, Hard-Reset, iTunes downgrade to iOS 9.3.5 (from both 10.0.2).

After all things didnt work and the Touch ID fails, I have a bad thought, that Apple did something in iOS 10.0.2 which prevents the Touch ID to work after the iPhone was disassembled. Something like in the past with the Error53… I hope someone can prove me wrong and help me out with the issue by providing a trick how to reset the Touch ID and complete the Touch ID Setup.

iPhone 5c: Why my iPhone 5c is never on time?

Sun, 08 Oct 2017 05:13:07 -0700

Hello,

My girlfriend bought an iphone 5c but we realize that it has a really annoying problem : the time on the phone is changing regularly.

Most of the time the date is right, but from one second to another it can be several hours late of early.

We tried to reset it and to change the battery and tried to switch on and off the automatic time setting, but the problem is still the same : the phone is never on time.

iPhone 4S: iPhone 4S display black and constant vibrating (sounds) when charging?

Wed, 24 May 2017 20:23:53 -0700

I was repairing an iPhone 4S for someone and all went well. I reassembled it and turned it on, but the screen was black. At first I thought the battery was flat, but the phone was on and working (the CPU warmed up etc. etc.) I plugged it into my computer and it makes the sound that any iOS7.x.x makes when you start charging it. Thing is it makes this sound every 10 seconds or so as if i'm plugging and unplugging it. The screen is still black all through this. I assumed that the LCD was dead. (at this point I'd tried cleaning the connections, reseating the connections, blowing the phone out with an air canister, restarting the phone, resetting the phone. (I haven't restored it as it's not mine and refuse to do it without permission for obvious reasons). None of this has worked. I gave up and fixed a few more things by this point the battery had ran dead and I plugged in a new 4S screen that I had lying around. I held down the lock button and it worked, the phone showed the "needed charging" icon so I plugged it in and let it charge for 30 minutes. I came back and all was working well, so I unplugged that screen and plugged in the installed one, and truth be told the screen was black again. I plugged in the other screen and it was black too. I tried 2 more (cracked but working) screens and they were black also. I replaced the battery and it was still black. If it was a faulty LCD why would it not work with the other screens? If it was a damaged motherboard why would it work, not work, work, then not work again? I'm baffled. It's also recognised in iTunes, but has a password (which I have, but I don't know exactly what I'm pressing so unlocking it is a pain)! Any help would be greatly appreciated as this is the first time it's happened and i've fixed probably 40 iPhone 4S's. Thanks in advance! :)

iPhone 5: Why does my phone die at a very high percentage?

Sat, 24 Apr 2021 14:42:48 -0700

For a while, my phone has been gradually increasing at when my phone would die.

(eg, a month before my phone would die at around 40-50%, now it dies at 90-100%)

This happened a while ago with the same phone and some how, my phone fixed itself (I don't know how it happened) and it went back to normal (dying at 0%). But, the problem repeated again and I've tried everything (DFU restore, discharging and leaving it overnight) and my last resort is buying a new battery or even a new phone.

I've seen some posts where people say you run a battery-intensive app and let it discharge until 0%, but it's impossible for me, since I can't reach even below 50%.

When it dies, it stays at the flat battery screen and will instantly reboot once a charger has been plugged in.

Info about my phone:

-Bought my phone from a friend

-I have gotten the battery replaced, so my warranty is voided

-iOS 9.3.2

I would like to not buy a new battery, as it costs a lot of money.

Suggestions thanks :-)

(edit- when I reboot it, it goes to a different battery percentage, different to when it died. eg it died at 100%, but when rebooted it shows 96%)

Hi everyone, I am having a very annoying issue with my phone. I have replaced the battery 2 times, with both working for some time. It would eventually turn into my iPhone working, but shutting off at random with the battery meter indicating 60% left. It was like that for a bit, but now my phone won't even get past the boot logo and it keeps restarting on its own. Goes apple logo, 10 secs later, the logo fades off then restarts all over again.

iPhone 6s: iCloud lock removal by hardware replacement possible?

Sun, 18 May 2025 18:00:59 -0700

This question might be slightly different from some of the other questions asked about this topic.

Obviously, it can be done by replacing a few chips on the logic board and reprogramming the NAND chip or something like that.

But, my question is, can you somehow reprogram the EXISTING chip that came on the iPhone or is a new one needed? I saw a forum somewhere where someone had tried this but never updated his post.

Also, some special tools and software are needed for this type of project. I would love to know specifically what kind of software and tools are needed for this kind of job, and also, where I could buy them.

There are plenty of sites that sell this kind of material, but I want to know a reputable site that sells quality products and someone who doesn’t scam you into giving them your credit card information but never gives you a product.

I plan on repairing and flipping phones later in life as a side-job and depending on how much the chips cost that need replacing, doing iCloud unlock by hardware replacement. I don’t know how much the chips cost or anything like that, but considering you can get an iCloud locked iPhone 7 for about $50 and sell it for around $400, this may be profitable.

Thanks for your time and answers, they are much appreciated!

iPhone 5s: Discussing methods for performing a glass only repair as a business?

Mon, 11 Aug 2025 00:25:28 -0700

So as the title says, I'm looking to start performing glass only repairs on iPhone 5S's, 5C's, Samsung's etc. There are several methods ranging from several price ranges, but for what I want to do I want a high success rate, and 0 bubbles. I want an efficient business setup (I am a business owner) to explore these cheaper repairs.

These are the two things I was looking;

The first, LOCA (Liquid Optical Clear Adhesive) Which is applied on the screen after separation and cleaning then after the removal of bubbles it is then cured under a UV lamp.

The second, OCA (Optically Clear Adhesive) which comes in pre-cut sheets that are applied to the LCD and the glass is attached.

I was originally leaning towards LOCA, and now OCA, but I have queries with the pressure methods of removing residual bubbles in the gap between the glass and the screen. There are two ways to remove bubbles, an autoclave, and a vacuum chamber. I am wondering, for anyone who has experienced, which works better for what method? Also, if the vacuum chamber is a viable option, do you think it would be possible to make your own (having the knowledge and tooling of course). Is heat necessary when removing bubbles? To my understanding it works best at roughly 60 degrees centigrade(140 degrees Fahrenheit). How do you heat the screen in a vacuum? Would any autoclave work? Or would I need to fork out the $1500 for a purpose built autoclave? What pressure is required for these bubble removals? I'm looking for the most cost effective professional method for performing glass only repairs on phones, while still having some level of automation and a high success rate? What do you guys recommend? I really appreciate any tips from guys already doing this. Thanks so much! :)

P.S. Could anyone explain exactly how each bubble removing method has an effect on each type of screen adhesive? I have heard that using an autoclave with LOCA would make it spit out the sides? The vacuum chambers make the bubbles expand and then come out the side, how long does this process take? It just seems to worsen it while looking at it. Sorry for all the questions but it's a lot to invest, especially for someone of my age (15).

Sorry if this belongs in Meta, I wasn't quite sure.

iPhone 3G: iPhone constantly searching for carrier (no service)

Fri, 07 Jun 2019 10:39:47 -0700

Hi,

I dropped my iPhone, and now I get a "no service" message.

When the phone boots up (or after switching the airplane mode on and off) it finds the signal (at the weakest level)—but after 10 seconds, the signal is lost and the phone starts searching for the carrier again...

Everything else works normally (WiFi, etc.), and I can use it as a "Skype" phone, listen to music, and surf the web.

My OS is 3.1.2 (with 05.11.07 baseband).

I tried the following (without success):

Doing full restore with DFU mode on clean iTunes
Opening the iPhone and making sure no cables are loose
Switching off 3G

Does anyone have any advice? What else could I try?
