iPhone 11 Pro Max: 11 Pro Max Screen Removal

Thu, 22 Jan 2026 17:58:23 -0700

I was trying to remove my iPhone 11 pro max screen and the top left corner is just stuck. It seems like it might be a clip or cable it's stuck on and not allowing me to open the phone. I opened this phone before with no problem, What can I do without breaking the screen?

iPhone 11 Pro Max: Will the LCD Screen Replacement Cause Board Damage?

Tue, 25 Apr 2023 09:41:14 -0700

Hello everyone, new here.

So, i have a completely destroyed iPhone 11 Pro Max that i would really like to fix up to avoid it becoming just more e-waste. Question is, i’ve done a bit of research on LCD displays retrofitted onto OLED iPhones and from what i see they usually cause board damage because of more power draw, but i wanted to find out if this magically happens to not be the case with the iFixit display.

Thanks a bunch for all the help!

iPhone 11 Pro Max: I Wiped my Phone Screen with 75% Alcohol please help

Sat, 16 Oct 2021 09:23:17 -0700

I’m not sure it’s due to this but recently my iPhone screen has been dimming even I’m still using it. I sprayed it one time on the tissue and gently wiped on just the glass protection part of the screen. Do you think my phone is damaged? It doesn’t happen all the time, it happens sometimes. I used 75% cleaning product not the type for medical use so I’m worried. How can I check if my phones ok?

iPhone 11 Pro Max: Battery change with old battery board

Sat, 13 Jan 2024 21:09:00 -0700

Hello, I bought a new battery for my iPhone, but since I don't have a programmer, I wanted to put the old circuit board on the new battery and no matter what percentage of capacity it shows, i want the foreign battery message to disappear. However, after replacing the circuit board, the phone does not want to turn on, it constantly lights up that there is no battery, and once it happened, the Apple logo was flashing, but now it constantly shows that there is no battery, can you give me some advice?

Just to add, I was looking on the internet at an iPhone 11 battery change and they put 4.2 volts of current on the battery somehow to activate the BMS chip and I don't know if it's that or something else!

I forgot to say that it is probably not necessary, but it only works in the charger and shows that there is no battery

iPhone 11 Pro Max: Person called hears static noise during call when on hands free

Mon, 09 Oct 2023 22:29:22 -0700

I am stuck .

I started on an impossible job.. Replacing the glass on the back of an iPhone 11 pro max. Cracked the new glass when refitting and decided on replacement of entire case. Received a very substandard item . many internal screws were missing and the charging port needed to have the top part re-soldered onto it from original. I would have returned the thing but was on tight time constraint as client was moving home interstate.

Completed the job and found the the phone was doing a restart every 3 minutes. I did some research and found out about the panic log in the privacy folder analytics. There was a mic2 panic log that indicated that the power button flex may have been the culprit. I replaced it with the original apple from the old frame . the phone stopped the continuous reboot but still has a static hiss when using the phone on the hands free mode and for doing voice memo’s . There is no static when making a video recording or making a call when holding the phone to the face.

I hope that the fault resides in the power button flash flex .

Can anyone give me any guidance with this mystery. The owner says that there was no static previously. All of the information on problems seen to either point to the charging port or the power button flex (non OEM parts).

Am I missing something here? Prefer not to be informed that it is mother board.

Can anyone help me???

iPhone 11 Pro Max: Lower battery connector overheating upon battery replacement

Sun, 18 Dec 2022 10:47:49 -0700

I recently had an iphone 11 pro max heat up and go dead on me. Guessing it was the battery, i replaced it, and immediately upon plugging in the new lower battery cable (into the power distribution board thingy near the lightning connector) that plug began to get very hot, to the point of burning my finger within a few seconds. I unplugged it and, through process of elimination, tried disconnecting every other component from the lightning connector. Each time the battery cable still got hot. I tried cleaning out the battery connector and the charge port with alcohol and compressed air to no avail. I have also had issue with the lightning port intermittently not charging before. I am thinking that I have a short somewhere in the lightning port or the greater component including that port, but I wanted to ask: is there any world where that behavior is normal upon pluggin in a new battery? Is it possible that replacing the lightning port may not fix my issue? Thanks in advance.

iPhone 11 Pro Max: My phone constantly shuts down, after working normally for 1-3min

Tue, 25 Oct 2022 06:23:35 -0700

This is not afaik the apple logo loop, the phone works normally for a few minutes and then shuts off in the middle of whatever I happen to be doing. About a week after the warranty was up, the microphone stopped working, and I could only use the phone with a headset, but otherwise the phone worked normally until now. The battery reads full. I have restarted the phone, I have done a reset, and I have done a full backup and DFU and reinstalled everything. My theory is that the charging port and microphone are so close together that somehow damage occurred to both. This first buggered the microphone and is not maybe shorting things out? Not sure how to proceed. I have never previously had a problem with any apple product, so this time I decided not to buy apple care. the apple store wanted 600$ to look at mic, and said if there was evidence of water damage it would be unfixable. AFAIK it has not gotten wet.

iPhone 11 Pro Max: NFC and Bluetooth problems

Sat, 21 Aug 2021 16:42:40 -0700

Where is this located? Dropped the phone on the top in an otter box but now the NFC doesn’t work and Bluetooth audio streaming keeps dropping and reconnecting. Bluetooth phone calls are fine. Flashlight is also spotty works and doesn’t sometimes. Is this a connector or a brass pin connector or a bad chip? Already had this issue and phone was replaced under limited warranty. It’s happening again after a drop. I work in the field. Update: it drops connection when the top of the phone is sandwiched lightly Around the area of the mute switch. If I squeeze it, it drops and comes back after a few seconds. It’s a full drop connection

iPhone 11 Pro Max: "Ghost Touch" Display will randomly start pressing buttons.

Thu, 29 Apr 2021 10:58:36 -0700

So I replaced the screen of an iPhone 11 Pro Max. Repair went fine and everything seemed routine until the client reached out a couple days later saying the the display was acting up. After asking a couple questions and looking at the display to see if everything was still connected correctly, I gave them the phone back.

A couple more days passed and now they reach out again with a similar problem so I assume it was just a faulty display and I replace it with another new screen I have from the same supplier. Same problem a few days later.

Has anyone dealt with this before? At this point I think there is further damage to the phone besides the display or this supplier just has some terrible screens.
