iPhone 12 Pro Max: Unable to verify this iPhone has a genuine Apple battery.

Thu, 11 Sep 2025 02:05:40 -0700

I bought an iPhone 12 Pro Max on Facebook Marketplace and I was in a hurry and didn't check the unit properly, when I get home I stumbled this message "Unable to verify this iPhone has a genuine Apple battery."

Does it mean the battery of this iPhone got replaced with non-genuine product? And how can I fix get rid of this message? I'm planning to resell it but I need to fix the battery problem first.

The seller deleted his Facebook profile so I couldn't return this iPhone. Thanks for your help in advance.

iPhone 12 Pro Max: Software screen burn issue linked with IOS

Sun, 23 Jun 2024 20:34:20 -0700

I assumed the screen burn was due to excessive brightness on one static image that burnt the pixels in on this iPhone. I replaced the OLED and the screen burn is still there! Its a common issue in the new iPhone 15's and an IOS update was meant to fix it. I have tried restoring, flashing and updating. Nothing has helped. Has anyone had a similar issue and know of a fix, its quite frustrating that I now have a new screen that looks like its got a defect.

It is not a screen issue I have checked with another genuine display and it displays the same burn in on this one too. Seems to be programmed into the software. Anyway of wiping IOS completely and installing fresh?

iPhone 12 Pro Max: Lost track of screw

Fri, 22 Sep 2023 16:38:52 -0700

While doing a housing replacement, the magnetic mat fell off my desk and I lost most of my screws. I ordered replacement screw pack, but I do not know what type of screw goes where on the phone, and I heard it could damage the phone by putting the wrong screws on the wrong location. Is there any guides to know what type of screw goes where on the phone.

Is it possible to replace this rear camera in a 12 pro max and it remains working 100%? I ask this question because I could see in a video that when replacing the camera in the iPhone 12 it has problems like portrit mode or frizing the image etc.

iPhone 12 Pro Max: Which flex cable did I cut?!

Tue, 23 Jul 2024 12:45:28 -0700

I cut the flex cable that is exposed in the bottom left corner when I was replacing the back glass. And where can I find a parts diagram for this phone model?

I purchased this phone as is. Someone had previously tried replacing the back glass and front screen and quit. The one was functioning when I purchased it. Now I just need to figure out which flex cable it is. Thanks so much for any help.

iPhone 12 Pro Max: Problems after screen replacement

Mon, 27 Nov 2023 00:35:50 -0700

Hey, I replaced the display on my 12 Pro Max with a cheap OLED display because I didn't want to spend a lot of money on it, but the display only lasted some days because it cracked on my pocket, but I kept using it for some weeks, the display was half green and kept turning off (locking the phone and unlocking would fix), then one day it turned off and never turned on again (phone was still working fine, only the display was off), so I replaced again with a even cheaper display (LCD), but this display never worked, only the touch part works, I already tried to clean the connectors, plug them again, force reset the phone, and nothing fixed it, but if I enter recovery mode, the screen turns green (pic below). So, what can be the issue? its possible the first cheap display fried the display part of the board? or its possible the second display to be damaged already? DFU restore have any possible chances to fix this? Thank you for the help!

Dropped my phone this morning, only the glass broke.

I had the back glass on my iphone repaired at a kiosk in the mall, however since then the auto focus on the back camera will not work. Any thoughts on what may have caused that? I can go back or go to a different repair place, but any suggestions if I should try anything?

Thanks
