iPhone 11: Restarts every 3 minutes because of thermalmonitord

Thu, 16 Oct 2025 00:36:31 -0700

Restarts every 3 minutes, Panic-full logs mention "missing sensor(s): Prs0”

Panic full log: https://pastebin.com/MVKxS4h4

This phone has had the screen and housing replaced, people on reddit suggested changing the battery but that didn’t fix it, thinking of changing the lightning port flex cable. any idea about where exactly is the “Prs0“ sensor?

Thank you, any help is greatly appreciated.

iPhone 6s: Can an iPhone 6s Screen be transferred onto a normal iPhone 6?

Fri, 29 Dec 2023 15:17:02 -0700

I recently shattered my iPhone 6 screen and it's no longer working, and I'm extremely interested in the 6s but don't want to drop $900 for a new phone when mine just needs a new screen.

So, my question is I can purchase an iPhone 6s screen and install it to a iPhone 6, and would it work?

I'm extremely curious to if this is possible and willing to try.

iPhone 6: WIFI signal is weak, which part should I replace

Thu, 18 Apr 2019 22:43:46 -0700

My iPhone 6 wifi is very weak unless I'm RIGHT next to the router. I've tried all the software fixes, and determined it's hardware.

Will simply replacing the antenna or the antenna cables fix it or is this a common issue where the chip on the mother board is bad?

If it's the antenna cable or module, which one is better to try first? I don't want to buy the wrong one.

Is it more likely this: iPhone 6 Top Left Antenna

or this: iPhone 6 Logic Board Antenna Flex Cable

Thanks!

iPhone 7 Plus: Why is my microphone not working at all?

Tue, 28 Dec 2021 20:19:31 -0700

My iPhone's microphones stopped working completely, I tried to test it by recording a video and there is no recorded audio from any of the mics. When I tried using voice memos it wouldn't even let me hit the record button as if it can not detect a mic. The speakers do work by the way.

iPhone 5s: iPhone could not be activated because the activation server cannot be

Fri, 30 Apr 2021 10:05:02 -0700

After formatting my iPhone 5s for selling, I went to the normal front page for setting it up. As normal I did the setup, but then when the activation page came it loaded for a while and then the message 'iphone could not be activated because the activation server cannot be reached' comes up. I tried retrying for a long time but no luck. Besides as found from the web to connect to iTunes and restore/update, I followed those steps too but still the same thing comes. (When I put a Sim card it the signal strength comes up and there is nothing written beside it... Any solutions? Would be a lifesaver

iPhone 4S: Why isn't the right side of my iPhone 4S touchscreen working?

Fri, 12 Apr 2019 23:46:27 -0700

I first noticed that the right side of my touch screen wasn't working while writing an SMS when I couldn't type the letter "P". It works in landscape mode but not portrait (because it is a different location on the phone.) It works to launch apps but if I need the very right side of the screen it doesn't work. (For example, jumping to a certain letter in contacts or moving an app from the 1st page to the 2nd.) There is no damage to the screen or water damage to the phone. Is there a part that needs to be replaced or a connection that needs to be checked? Thank you in advance for any help or advice you can give.

iPhone 6: How can I remove a striped pentalobe screw?

Wed, 07 Mar 2018 17:36:24 -0700

Hi all,

I have recently purchased an iPhone 6, 128gb space grey with a cracked screen. I need to remove the pentalobe screws to replace the screen and get the phone up and running.

Unfortunately the previous owner has completely stripped one of the pentalobe screws and I can not remove it with the correct tools. The screw has no shape left whatsoever (see photo) and will not grip at all.

I have tried different shaped screw drivers, the rubber band method and a stanley knife. I have heard to try super glue but I am scared it will seep into the thread and make it harder to remove. What is the best method to remove the screw?

iPhone 6 Plus: Speaker phone option is greyed out

Sat, 02 Aug 2025 07:03:37 -0700

I have had this issue before, took it to a cell phone repair shop & it was an easy fix..but I can not remember how they fixed it. I don't want to take it anywhere due to it being this easy. The speaker phone button is greyed out when making/receiving calls, which means when someone tries to call or vice versa I can not hear. My music and videos play with sound just fine-the volume is turned all the way up with the ringer being ON.

I have reset network settings and reset all settings and still nothing. Can someone please give me a helpful, real solution to fix this problem?? I have searched all over the internet and found nothing helpful.

iPhone 5: iPhone5 display randomly goes black.

Thu, 14 May 2020 19:58:44 -0700

My iPhone5 is out of warranty (2 Years old). My problem is that my display goes black after some usage (on average less than a minute time). I think this is not the normal display problem of black scree. I have already done home+power restart, restore/update to latest software.

History of problem: One day my phones display suddenly went black. I googled and quickly found the home+power button solution. Upon restart my display was on for some time and then again went black. After that since last 15 days my phone display goes black after some random amount of time and then after waiting for some time and pressing power button it again turns for some time and then again goes black. The more I wait the longer my display stays on after turning on. I can receive calls and messages etc when the display is blank. Another piece of information that I think is the major to pinpoint the problem is that, 3 months ago some my phone got some water damage after I was drenched in rain and there were some white spots on the display due to that. The amount of water was very less and My phone was working fine except those annoying small white spots. I want to repair my phone myself as there are not many good service options in my country but I am not sure if it is a display problem or some other chip/cable problem. If anyone has a clue what could be the exact problem that would be a life save for me.

iPhone 5: iPhone 5 front camera wont work after front screen replacement.

Mon, 20 Jan 2020 04:26:12 -0700

I run an iPhone repair business in the UK, so I do have a reasonable amount of experience with these devices and until iOS 7 came out I had no issues with this problem I am about to explain. A customer came into the store yesterday with a broken screen and power button on the iPhone 5. So I replaced the power button flex to fix the button and replaced the screen with an original part. But then when I turned the phone back on everything worked perfectly apart from the front camera. I have sent my customer away to restore the device and then Im sure he will be back if it doesnt work, but does anyone know a fix for this? (I am always extra careful when removing the digitizer and camera flex cables, and yes I have checked if its plugged in correctly three times.)

Every single time I do a simple screen replacement on iPhone SE, I turn it back on and it stays at 1%. That's it. Before repair, charging normal. After repair, doesn't charge at all and stays at 1%. This has happened 8/8 times.

iPhone X: Help me diagnose iPhone X Face ID move iPhone a little lower

Tue, 01 Feb 2022 05:58:52 -0700

Hi! I have an iphone x with face id and selfie camera portrait mode not working. For the moment I don't know if any of the internal components were changed or not.

Here is what I know:

face id fails to detect a face during the setup process. Keeps sending the two messages: move iphone a little lower/higher
Animoji works ok though
Flood illuminator also works as I can see it with an older camera
Proximity sensor and autobrightness are functionally
Attention thing works (when picking up the phone it turns display on if it detects any human face)
Front camera works (without any blur) aside from the portrait mode (It says move further away and only takes a normal photo)
Back camera works ok, portrait mode is functioning
Phone has liquid indicator turned red (unfortunately I haven't saw this before buying it)
The phone seems to have been opened up before as the adhesive was loosen whet I opened it up.
I have tried to clean the dot projector and the infrared camera along with the lens on the front glass but without luck
I have tried also the DFU restore, and every type of reset
Iphone is running ios 12.3

My question is that if the display is changed without transferring the other components from the glass assembly, will iphone send the faceid unavailable error or it could just never let you setup it like in my case?

Has anybody been able to repair an iphone x with these symptoms?

Thanks a lot!

iPhone 5s: Rear camera and flash don't work

Tue, 30 Mar 2021 05:23:03 -0700

Greetings! First post here.

Recently, while in the dark, I noticed that my flashlight (camera flash) on my iPhone 5S was no longer working when activated from the control center. I then began to debug it by rebooting, resetting and then finally by upgrading from iOS8 to iOS9. None of these fixed my problems but during the investigation, I noticed that the rear camera was no longer working as well. After some internet searching I do not really have a clear idea of whats wrong, as such, is why I am here.

This is something that I would like to try and fix myself if possible but would like some ideas of what else could be wrong here and if there are any additional debug steps. After hopefully identifying the problem, I will likely need to purchase the part(s) and doing the repair... so any thoughts or advice here would be welcome as well.

Thanks in Advance.
