iPhone XS Max: iPhone XS Max Taptic Engine screw stuck - Step 37 battery replacement

Tue, 23 Jun 2026 21:17:28 -0700

I am following the iPhone XS Max Battery Replacement guide and am stuck on Step 37. I cannot remove the bottom 1.9 mm Phillips screw securing the Taptic Engine. I have tried applying extra downward pressure and using a rubber band for grip, but it still won't budge. The screw head is starting to look stripped. What are the best next steps to remove this specific tiny screw without damaging the surrounding components or the battery?

iPhone XS Max: iPhone wont turn on after fall

Sat, 17 May 2025 02:51:41 -0700

I dropped my iphone xs max and it suddenly went black. I tried hard reset but the screen wont turn on. Also tired plugging in the power connector but it started to get stuck in the reboot loop where the apple logo keeps appearing and disappearing with some green lines glitches. Tried also open up the phone and check the connectors, all seem to be fine, i even removed the motherboard to check things below it, nothing seemed wrong

Can someone tell me which component module might went wrong? And how can i fix this?

iPhone XS Max: iPhone XS Max restarts when it's not in use.

Tue, 24 Sep 2024 21:19:13 -0700

The problem is that my iPhone XS Max restarts when it's not in use. When I'm using it, or when something like music is playing in the background, it works fine. However, the moment the display is off and nothing is running in the background, it restarts. Another thing I’ve noticed is that it heats up very quickly, even during normal usage.

For context, the battery was recently replaced at an Apple Authorized Service Center, and the battery health is at 100%.

Here I share the Panic String:

"panicString" : "panic(cpu 2 caller 0xfffffff014271f4c): \"i2c0::_checkInterrupts error interrupt; last read status 10810100 int shadow 00890100 xfer 80000000 fifo 00000003 for device ad5860\" @AppleS5L8940XI2C.cpp:503\nDebugger message: panic\nMemory ID: 0xff\nOS release type: Beta\nOS version: 22B5045g\nKernel version: Darwin Kernel Version 24.1.0: Mon Sep 2 22:21:50 PDT 2024; root:xnu-11215.40.48~34\/RELEASE_ARM64_T8020\nFileset Kernelcache UUID:

If someone can help me identify the exact problem, I’d really appreciate it.

iPhone XS Max: Why is my phone not charging when it is on?

iPhone XS Max: It is the battery cell or BMS that is damaged?

Sun, 28 Jul 2024 14:11:11 -0700

Hello,

I change the battery of an iphone xs max, and at first, after spot weld the old bms to new battery cells and reprogramate (with i2c i6s) the iphone did not show the 100% (on the i2c reading was reseted). Also did reset the battery health by applying an none original on iphone.

IOS was updated to date and nothing (17.5.1).

On the other day i wanted to try again, but the battery was dead and i recharge and the phone keeps turn on and off right away. Only with the fixed battery, with the none original one is ok.

So my question is, how can i know if is the bms that was damaged during the spot weld or the battery cells?

Thanks everyone for the help.

iPhone XS Max: Why is my phone screen unresponsive?

Mon, 17 Jun 2024 06:31:03 -0700

Recently, i was at a swim meet. (and no, NO water touched my phone.) I left my phone out on the chair directly in contact with the sunlight (and it was pretty hot.) when i first picked it up, the screen was extremely laggy and slow to respond because of how hot it was. but then, i started to notice even when it cooled down that the phone screen was unresponsive. sometimes when im using it, it randomly just stops working and i have to wait about 30 seconds for it to start working again. its been 2 days, any ideas how i can fix this?

iPhone XS Max: XS MAX Flexcables cut off - replaceable?

Sat, 18 Nov 2023 06:58:55 -0700

Hi all,

I tried to replace my display on an old XS Max. Unfortunately, I broke 2 flex cables... (marked with green arrows on the photo).

I understand the lower one is that of the FaceID/Front camera. Can I replace that one, is that possible?

Also, what is the upper flex cable that I broke as well and can I replace it as well?

Phone boots up (I gotta say, the display is really, really, bad)...

Kind regards and thank you!
