I bought a new battery and it powered up fine, but quickly got very warm and started to die very quickly. I plugged it in, powered it off, and left it overnight. I was not able to turn it on the next day. The new battery does now not ready anything accross the sides of the ribbon cable end. I havn't taken this battery apart yet.

Does this mean that the phone is damaging the ribbon cables (drawing too many amps) from a bridge in the phone itself. Any ideas?

Thanks

I found out today that a small metal pin on the bottom of my iphone broke off. It doesn't seem to affect the phone at all, but can someone explain to me what it's for?

I can see that it was supposed to touch a dot on the back of the screen.

I have marked the small metal pin in yellow at the bottom of the phone.

I hope you can help me answer this question, thanks

• One screen had a good display, but the touch didn’t work.
• One screen showed nothing at all—completely blank.
• One showed the Apple logo, then went black.
• One just displayed colored lines.

At this point, I was going crazy.

Then I happened to get another iPhone 12 mini. I tested the screen that was previously totally blank on the new phone—and it worked perfectly! The display and touch were fully functional. So I went back and tried the same screen on the original phone again, but still just a blank screen.

I should mention: the original iPhone 12 mini did have a semi-working screen before I started. The display was mostly fine, but it had two vertical green and yellow lines running top to bottom.

So now I’m wondering—what could be wrong with the first iPhone 12 mini that’s preventing it from working with the replacement screens?

Would you like help diagnosing the issue, too?

Is this just an easy fix by just replacing the back glass, or I need to do more work?

I was replacing the battery on my iPhone 12 while following the iFixit guide. Unfortunately, the guide didn’t mention that OLED replacement screens for this model can be significantly thicker than the previous models.

As a result, when I tried to open the phone, I mistakenly started prying between the layers of the screen itself instead of between the screen and the frame. That ended up damaging the display.

Later, when I replaced the screen, I noticed that the proximity sensor was also damaged, and now Face ID no longer works.

To make things worse, Stolen Device Service has been activated, and I can’t disable it without working Face ID. So I’m stuck in a loop — I can’t fix or access anything critical, and I can’t turn off the security feature either.

I’d really appreciate any advice from the iFixit team or community on what I can do next. This all happened while following the iFixit guide, and a small note about the screen thickness could have prevented it.

Thank you!

I took it to the Apple Store, where they attempted a software update via iTunes, which failed. I also tried the same at home using an original Apple cable and a fully updated Mac, but received error code 9. I then tried several third-party tools that claim to fix bootloops without data loss, but none were successful.

Unfortunately, I do not have a backup, and the device contains important and irreplaceable photos and videos. As such, I have avoided performing a factory reset via iTunes, since data loss is not an option for me.

I understand the importance of backups now, but I’m urgently looking for a solution to recover my data. Could this be a hardware issue (e.g., a faulty earpiece or connector) that’s causing the bootloop? If so, is there a way to temporarily stabilize the phone just long enough to create a backup?

Any guidance would be deeply appreciated.

When it's on, it seems to work normally, with some exceptions. The option to turn on the Wi-Fi in Settings is greyed out and set to "off". The Bluetooth menu only shows a loading wheel, and does not show any of my previously connected devices. The phone also gets a bit warm, even if I do nothing.

I've used one of the tools linked on the repair.wiki page for this problem, which told me that the problems indicated by the panic logs are "Charging Port Flex", "Power Button Flex", "NAND", and "Wi-Fi Module". The last of those panic logs is here: https://pastebin.com/ay5hS2eS

I have replaced batteries on the iPhone 4 and 6 before, but I've heard that the newer iPhones are much more difficult to repair. Is this problem easily fixable, or is this something I should bring to an Apple store?

I ripped the GPS antenna during the work(the one at the top left). Could it remit to that?

If not, then, what? Because everything else was mounted impeccably... Can't think of any other damage done.

I bought a relatively cheap iPhone 12 Mini for my brother today just as a temporary phone.

I didn’t notice at the time, but it’s actually a Chinese-region iPhone (says WLAN instead of WiFi in settings - that was the tell). We are in Australia and I can’t seam to find anything that doesn’t work on it, so was just wondering if there is any functional difference in using an iPhone that is from a region outside it’s used-in country?

Thanks!

The next time I went to turn it on, which (stupidly) was later that evening, I found that there were green lines going across the screen and it had either a bit of a purple tint or green tint to the screen. I powered it off, but, eager to get to work on a project for my education, I tried again the next morning and the screen was black even though it felt like it was responding to my touch sometimes, and notifications were coming through too as my watch was receiving them. I could also hear and feel things from my phone as well.

It's been like this for about 5 days, and I know I probably shouldn't have but have been powering it on occasionally just so I can check my notifications and help things with my fully functioning watch. Sometimes I can see the screen, but it is only normal for a second, then gets a purple-ish or greenish tint and/or lines on the screen. This was mostly in the beginning, and now it usually goes black.

Along with the first bit of issues I received an error that face id was not working and when it gave me the option to go to settings, it didn't take me anywhere helpful.

What can I do? Because it is water damage, I'm worried it may not be able to be professionally repaired.

Update- now the screen is black and hasn't turned on again so far but flashes or has green or white bars on it usually at the bottom.
