Sun, 13 Mar 2022 11:41:25 -0700

When 3D Touch is activated or any vibration occurs, the Taptic Engine makes a rattling noise that either sounds look a faulty spring or perhaps a loose screw in the device quite possibly being the screw used on the audio jack based upon the tear down photos posted. What could possibly be the issue and or fix?

Someone on ios 11.3 Beta with an iFixit replacement Battery yet? It shows 'Service' in the new Battery Health Tab.

If you scroll down on the following Article, Apple explains that:

Battery health unknown

If iOS is unable to determine the device battery health, you'll see this message:

This iPhone is unable to determine battery health. An Apple Authorized Service Provider can service the battery. More about service options…

This may be due to having an improperly installed battery or an unknown battery part.

iPhone 5s: Battery drain after screen replacement

Sat, 22 Sep 2018 06:23:18 -0700

I recently replaced my iPhone 5s digitizer/screen and everything works fine but now it seems like the battery drains almost 2x as fast as it did before the screen was changed. I can't figure out what exactly could be wrong and reopened the phone to see if there as anything loose or disconnected but everything looks fine and functions correctly.

iPhone 6s: iPhone 6s Searching/No Service

Sun, 08 Sep 2024 02:47:17 -0700

I have an iPhone 6s that has the searching/no service issue. I've seen this a lot online with the iPhone 6/6 Plus, but no one really talks about it with the 6s. Is it caused by the same baseband ic issue or is it another chip? I've looked around to get this repaired, but no one really seems to offer this service. Does anyone know where I can get this chip reballed? Thanks in advanced!

iPhone 5: Full brightness dimming problem

Sat, 26 Feb 2022 13:33:42 -0700

HI I have a iphone 5 and the glass of my screen was cracked.

I bought a new lcd with digitizer from ebay and replaced that with an old cracked one.

It works fine but the even though i changed setting to full brightness, it's not bright enough compare to my friend's iphone 5.

Auto-brightness is turned off

So I replaced it with my old one but still darker than others.

I also tried DFU but still the same.

I'm not sure why it happens.

Does the brightness is related to the mainboard?

I'm trying to purchase another lcd from ebay but I'm not sure what is the problem.

iPhone X: iPhone X rear glass replacment

Mon, 25 Apr 2022 22:00:30 -0700

Hi guys,

I want to know If anyone has replaced iPhone X rear cover glass, I know its replaceable but I'd like to get some more details on this repair, will it look so obvious to tell it has been replaced after replacement?

I've watched the repair on an iPhone 8, is it similar? and what to avoid?

Are there any recommend suppliers to buy a glass cover from?

Which method is better and safer, taking the board out and prying the rear cover?

Any recommendation would be appreciated.

iPhone 6: Black screen after lcd replace

Sat, 11 Apr 2020 14:28:26 -0700

First off I want to thank everyone for the help on this site. My problem happened right after I replaced the lcd on an iPhone 6. the screen is dark and I tried different screens even the original, still the same problem. when the phone is connected to power it intermittently vibrates, when connected to computer itunes picks it up but I cant access it because there is a passcode. I read about the longer screws damaging the motherboard and its not it (the shield wasnt on). I tried everything, even removing and re installing the board. same problem. I had a iphone 5s do the same thing and it worked after resetting the battery, this one has me stumped. Would appreciate any input, thanks in advance.

iPhone 5: iPhone 5 Black screen after screen replacement

Sat, 21 Oct 2017 13:02:42 -0700

I replaced a iPhone 5 screen for a customer the other day. It worked fine when it was picked up, but a day later they returned it with a black screen. The phone seems to start up when plugged in to charge and vibrates when muted/unmuted, but the screen stays black. Whats puzzling is that it doesn't seems to start when I only use the power button. I can turn it off by holding power button and slide the bar, so the touch seems to work.

Heres what I've tried so far...

Replaced it with the original broken screen.

Replaced it with several new screens.

Disassemble and assemble the phone.

Replaced the power button flex.

Put the motherboard in a new iPhone 5.

Nothing helps. Hopefully someone can enlighten me. :)

iPhone 4: Error 4005 Wont boot up but shows up in Itunes (DFU)

Sun, 15 Dec 2019 22:37:34 -0700

My Wife's iPhone 4 up and quit a few weeks ago. No signs of life on the charger or in iTunes. The dock connector was pretty corroded so I replaced that and the battery with no results. If I put it in DFU mode , it will show up in iTunes but gives me an error 4005 when trying to restore. I metered the charging fuses on the logic board and they seem OK. I'm guessing that would leave the charging IC ? Or am I looking at something else on the Logic Board as the cause?

iPhone 4: Wifi very weak after display replacement

Fri, 02 Dec 2016 23:21:28 -0700

Hi,

I just replaced a cracked display. Unfortunately after putting all back together, the wifi is just working when standing 1-5 meters away from the router.

I also tried to replace the Wifi antenna at the bottom of the iPhone, some of the EMI clips to the display assembly went off. The antenna cable is fitted in properly. I dont know what else I can check.

I have this wifi problem on 2 of my iPhones.

Help would be appreciated very much.

iPhone 7: Ripped one of the cables on LCD, but what is it exactly?

Thu, 04 May 2023 09:08:09 -0700

Hi!

I have disassembled an iPhone 7 but when taking of the screen one of the two flex cables from the lcd screen got ripped. The cable that got ripped runs upwards under the LCD part, to the top. The LCD and touch still work. (fun to know that the LCD and Touch both go through one flex cable). But it disabled the home button from working. I am trying to understand how the part that I broke runs underneath the hood and what I can do to solve it. Can somebody explain it to me with pictures where the cable runs to and how it works?

This is the Home Button cable. It’s very fragile for the iPhone 7 model. The solution is to buy a replacement screen. :)

iPhone X: iPhone X Error 4013

Hello

So I dropped my iPhone X on the floor!

Fortunately, neither the back nor the front glas has cracked.

But the phones does face another problem since then.

Shortly after the drop it shut down completely.

When I tried to turn it on again, the iTunes Symbol appeared.

When I tried to restore it, error 4013 appeared.

Of course I tried everything that is mentioned in divers troubleshooting guides like changing the USB port, changing the cable etc.

Of course I also tried the whole restore procedure in DFU mode and so on.

So please does someone know a REAL solution to this problem?

Thanks in advance

iPhone 5: iPhone 5 stuck in not restoring DFU mode!

Sat, 10 Feb 2024 21:31:46 -0700

Hi,

I have an Iphone 5 (A1429) that randomly went into dfu mode... I wasn't able to get out of DFU nor do a restore (itunes would hang on "waiting for device").

After charging the battery for a night (it gots charge now, checked it with voltmeter) i got it to a stage where it is dispaying the itunes logo with usb cable (recovery mode) but i can't get out of that either (tried holding home and power for 10 sec, restarts and goes back into the same recovery mode)

if i connect it to Itunes now, i get it to actually starting to restore but 10 seconds after the status bar displays on both my laptop and iphone, itunes stops with error 14. I already tried re-installing itunes, deleting old IPSW and tried other wifi/ computer. I'm desperate so pleas help, i'm willing to open up my IPhone and i'm in possession of a mac, windows and ubuntu PC.

here is the log i get (only error section):

[15:25:29.0492] Failure Description:
