iPhone XS: Unlock phone without passcode

Tue, 10 Mar 2026 21:58:05 -0700

Hi I have an iPhone x I own. An employee was using it. They never synced it whit iTunes. It might have faceid and it has a passcode. They have important info about an account on the phone. The employee is not with us anymore. They claim they forgot thhe passcode and if I try too many times it will disable the phone. I tried software program but it needs me to enable the the phone for it to work and since it is locked I cannot click enable. Is there anyway to bypass or reaet the passcode without wiping out this phone. The invoice about the client has value but not enough for us to rehire the ex employee. The issue is we look prooly in the eyes of this long time client. I will need to have a verification of a backup plan in place going forward but I trusted that this employee had done as asked and did not check their work regarding this. Please help thanks

iPhone XS: Top half screen don’t work only bottom

Fri, 13 Feb 2026 01:42:06 -0700

I’m a little puzzled, I replaced my logic board and after I was done I started it up to find out that the top half of the screen does not work. Only the bottom half works. First my camera was not working so I restored phone with new firmware but the top half just don’t work. I’m thinking screen but before i replaced the board the old board worked with the screen So I’m lost on this.

iPhone XS: Guide for swapping logic board between XS devices?

Tue, 06 Jan 2026 12:28:15 -0700

Hey all! I have a faithful iPhone XS that I have been using as a backup phone, but recently the already-cracked back fell apart a little more, and I am worried it will only continue to get worse.

My partner also has her old iPhone XS, but it is completely dead. Suspect some sort of logic board failure. Otherwise though, it's completely intact, in fact it looks almost new! I was wondering if I could potentially take my old XS board, and swap it into her iPhone's frame. Not sure what parts would be serialized (assuming battery warning message, and Face ID would stop working at the very least), but I think it would be the best course of action as the XS still supports our eSIM setup, making it a cheap backup phone.

The only issue is, I can't seem to find any logic board swap tutorials on here! Does anybody know if the process/screws are the same as the iPhone X? I have done similar swaps in the past, so I am comfortable doing so, but I would like to at least have an iFixit guide to follow along with, as I know the screws can all be different lengths.

iPhone XS: Stuck on 0% remaining and bootlooping every 3 minutes - iPhone XS

Thu, 04 Dec 2025 17:05:50 -0700

So basically, I got a replacement aftermarket battery for my iPhone XS. I plugged it in correctly to my iPhone and when powered on and plugged in, it says "0% remaining" and doesn't charge and it proceeds to go into a bootloop/restart every 3 minutes or so (the UI is also glitchy). To clarify and rule out the possibility of it being a board issue, I reconnected my old iPhone battery (stock OEM original from apple) and it worked just fine, charged, showed the indicators and worked correctly. Can anyone please give me insight as to why this aftermarket battery isn't working?

Regards folks!

iPhone XS: iPhone XS automatically shuts down once plugged to charger

Sun, 14 Sep 2025 07:54:56 -0700

Recently I replaced my iPhone Xs battery, my phone was working fine in starting for at least one week, then problem comes, here is weird problem, when i plugged to charger it start charging like normal, once screen goes dim & phone goes to auto lock, within one minute it auto shutdown & won’t charge, even if i press power button, it won’t power on, unplugged and plugged again, no effect, normally with plugged to charger iphone power turn on , but this won’t happen in my case, now if i unplugged to charger for 5 seconds, phone auto turn on & i even no need to press power button, weird thing is if i plugged to charger and let phone screen keep on, it charging normal like normal, phone battery work fine & it never goes auto off phone while using phone, not sure where to start find problem, as i already destroy my old original battery while trying to change original protection board of battery, i broke original battery flex cable, so i don’t have any other battery which i can try to check if that is battery faulty or phone motherboard it self or it might be charging board, phone can connect to pc with no issue and as i said it charging battery with no problem if phone screen is on so what i am doing is make auto lock never & make brightness to zero, so let it charge my phone, once it 100% i make it back to auto lock & increases brightness to normal, but this is not the solution, so i am wondering if anybody know what is all that, have anyone else faced similar problem?

any help shall be highly appreciated,

Thanks.

iPhone XS: Why is my phone suddenly acting up?

Sat, 30 Aug 2025 06:29:19 -0700

Hello good day, I have a question to ask. The device I have is an iPhone XS which was bought 2nd hand. And has a lot of issues, I mean mostly Hardware. Such as a cracked back glass and the replaced LCD. but the True Tone and Face ID works normally. After a few weeks I started experiencing random shutoffs when I leave my phone charging like idle. And also when I plug in my Wired Headphones it Also panics.the panics indicate a “panic(cpu 3 caller 0xfffffff029de57b8): "i2c0::_checkInterrupts error interrupt;

iPhone XS: replaced screen in digitizer and still no touch response

Screen touch stopped working. The front glass and rear glass are completely perfect. No scratches or broken. So I replaced the screen in digitizer with a ifixit part. Touch response came back for about two months and now the screen front and back is still perfect shape, but we are back to no touch response.

When that happens, the shown battery filling level drops to 0% and shortly after it will reboot with the mentioned error in the panic logs.

First I suspected that the error might be related to the lightning port. But replacing it didn’t fix it.

iPhone XS: Water adhesive for speaker after replacing battery

Tue, 22 Jul 2025 17:21:41 -0700

Hello, I haven't seen Ifixit done this guide before, but should I buy a speaker water seal adhesive after replacing battery? Ifixit recommends removing the speaker and haptic engine in order to remove the battery, but would that be compromising water resistance in the lower speaker? Or not? should I buy a new adhesive for the lower speaker or should I leave it like that and just use the screen water seal adhesive.

iPhone XS: Phone keeps turning off and won't turn on after screen replacement

Fri, 30 May 2025 07:11:19 -0700

I recently changed the screen on my iPhone with a 3rd party LCD screen as my old factory screen was severely cracked and displayed green all over. After I changed my screen with great care, I started encountering issues the same day where my phone would randomly turn off within minutes (and sometimes instantly) and wouldn’t turn on unless I plugged it in to charge, even though my battery was fully charged (for context, I replaced + calibrated my battery a week prior while using the original screen and encountered no problems).

I’ve noticed that sometimes, tapping it or setting it down will cause it to turn off. It will eventually turn itself off randomly, even if held in my hand or resting on a table, with the frequency increasing the more I turn it on and it dying until I leave it to rest. I double-checked all connections during the repair and tested the phone before reassembling to ensure everything works, with no issues. I had the battery unplugged while connecting the screen to ensure no discharge or damage. My first thought was the battery, but the battery is brand new and did not pose any symptoms or problems prior to me replacing the screen.

Why is this happening? I’ve heard some theories about components making direct contact with other parts of the phone’s internals which could cause problems. The screen I bought, while 3rd party and LCD, is from a reputable manufacturer (as far as 3rd party parts go), was bought brand new, and from a trustworthy seller. The screen is fully functional, so I’m less inclined to believe the screen is defective.

iPhone XS: Can I swap my XS motherboard with another XS?

Tue, 01 Apr 2025 00:32:30 -0700

My poor XS had been run over by multiple cars. To repair the phone would take a complete overhaul of the phone (housing, cameras, screen and all). None of the repair shops in Singapore would give me a straight answer to the possibility of swapping the motherboard from my totaled XS to another usable XS.

Thus, is it possible to swap the motherboards of an XS? Or, what other iPhones are compatible with the XS motherboard?

I just want my pictures back.

iPhone XS: iPhone XS turning itself off after using for a while

Wed, 26 Feb 2025 11:35:32 -0700

I decided to buy some phones for me to fix and sell, and the only one thats unlocked and somewhat working is just randomly shutting down and starting up again. Sometimes even when not in use. The battery is probably not the problem since i tried with 2 different batteries.

The only two things that come to my head is the iPhone X display i use for testing instead of iPhone XS display.

And I also see some signs of water entering inside the phone, and leaving residue.

I decided to hook it up to a pc and see the status in 3utools, and I got the crash analysis.
