iPhone 12: Screen stops working after replacement

Fri, 19 May 2023 13:16:05 -0700

After replacing the screen on the iphone 12 it will work fine and then just stops responding, sometimes right away sometimes days later. Open up unhook and rehook the same screen and it works again. Have tried other screens and it acts the same. Is this a software issue? Or is the iPhone 12 the vista of the iPhones?

iPhone 12: TBK 958A Not displaying iPhone 12 and up back glass laser schematics.

Mon, 08 Nov 2021 08:43:41 -0700

So we have a TBK 958a back glass laser machine and when the iPhone 12 came out we downloaded the schematics from the official website, loaded them onto a USB, put them in the TBK 958A and the file shows when we transfer the files to the machine via USB but when we click on the image it comes up blank. And I got my files directly from the website here http://www.shenwangda.com/en/h-col-125.h...

Has anyone here successfully updated their TBK-958A to fit the iPhone 12 and up models? We tried different formats on the USBs and that didn’t work. If anyone here has had some success please feel free to help a fellow tech out. :)

I dropped my phone in water and the screen stopped working and responding. It still responds with Vibrations when turned into silent mode and I turned the flash light on by accident too. I was wondering if there is any way I can recover my pictures to my new phone that were not yet backed up on my iCloud Photos.

iPhone 12: Phone keeps going in to recovery mode

Thu, 23 May 2024 12:23:13 -0700

Hello,

I am having trouble getting my iPhone 12 to boot up. The screen is damaged with vertical lines and when turned on it goes straight to recovery mode. I have plugged in to iTunes and it successfully completes the restore, however once it is finishes with the cycle it still boots in to recovery mode instead of ios. I have connected to 3utools and tried the exit recovery mode option but it just boots back to it,

Also, the phone won't turn on when pressing the side button, only when the charging cable is plugged in (stays on with cable unplugged after so no issues with battery). I am able to use the side button and volume buttons to reboot so I don't think any of those are stuck and forcing it in to recovery mode.

I have opened up the phone and tried disconnecting the earpiece speaker and front sensor assembly but it doesn't make a difference. Any ideas what could be causing it and what else I could try?

Thanks in advance

iPhone 12: Battery connector damaged while replacing screen - view for more detai

Sat, 05 Aug 2023 10:13:56 -0700

So I did a full test of 256gb iphone 12 which included face id working perfectly and screen brightness being fine, however upon damaging the battery connector the faceID does not work, the screen brightness is also lowered and the battery shows as non genuine (even though it is) and has no percentage at the top right when it used to. I just want to know if it is the battery that caused no faceid?

All these images contain an image of the front earpiece and connector, front sensor connector on the iphone 12 and also battery + battery connector. Only the battery seems to be damaged

iPhone 12: iPhone Camera Blurry After Removing Broken Glass

Wed, 08 Apr 2026 16:42:27 -0700

I cracked the camera glass on my iPhone, and after removing the old glass with a blow dryer and some tweezers, I noticed the camera won’t focus. Is this because I don’t have the glass cover on? I am waiting on a new one to ship right now. Also, I tried to clean the lens with a microfiber cloth and isopropyl alcohol, but that didn’t seem to help.

iPhone 12: iPhone 12 battery at 1% / not charging after replacement, old works

Fri, 30 Jan 2026 10:09:11 -0700

I'm trying to replace the battery on my iphone 12. The original battery works fine but had been used heavily and wasn't lasting as long as it used to.

I installed the replacement battery (from ifixit), but the phone shows up as 1% and there is no "lightning bolt" charge icon when the phone is plugged in. The battery menu in settings shows the phone as charging during periods when I leave it plugged in though. The phone locks and reboots periodically while plugged in, and 0% remaining" is displayed on the lock screen.

I saw other threads online with similar symptoms from different model iphones that indicated that I might have damaged surrounding components or circuitry. I took me a bit to get the new battery connector installed, but I did not see any loose pieces or visible connector damage on the phone.

I decided to test this by disconnecting the new battery and reconnecting the old battery. If the circuitry was damaged, I would expect both batteries to fail, however the old battery reports percentage, charges and the phone seems to operate fine when its installed.

I've tried reconnecting the two different batteries several times, and have tested with the screen on and off to try and rule out shorts as a possible cause.

The ifixit battery shows 3.78V on a multimeter when measured at the connector, while the original battery shows 3.8V (battery is rated at 3.83V). I inspected the connector on the new battery and can't see any obvious damage.

Any ideas on possible causes?
Next steps to debug?
Is it possible that there is an issue with the new battery?
