Tried restoring using both recovery mode and dfu mode. Both times it will get stuck on the same screen. What strange is that her esim is still registered even after restoring with dfu mode. Is this a hardware malfunction?? Have not seen this before.

I don't own a microscope, but the pins on the connectors look good under a magnifying glass. I'm no electrical engineer, but I'll happily become one to save the phone. Does anyone have any suggestions on my next move?

Here's a Google Drive txt of the (abbreviated) panic log. Below is the magic bullet:

Link to guide: iPhone 11 Pro Max Earpiece Speaker and Front Sensor Assembly Replacement

It seems that the flood illuminator is included in the earpiece that needs to be replaced. Anyone have any experience with this repair?

My phone is turning off suddenly every 3/4 minutes, then it turns on automatically. Important battery message shows after turning on the mobile. And the mobile is charging at 1%, and no battery health is showing. Again the battery health of the phone is showing for some time, everything looks normal. Then after running the phone again for a while the phone turns off and on again and the Battery important message is showing.

While doing a back glass repair I managed to rip both the small microphone sensor under the flash and the gold/white sensor to the right of it. I've gone through the data logs and found an error for a missing sensor Mic 2.

I've read from other forums that this is the Power Flex Cable. My question may be a bit silly but would the power button continue to work given this error?

The phone and power button both work as they should, but the phone will reboot after 2-3 minutes. Looking on mobilesentrix to get a replacement power flex cable, it should be OEM correct?

Any advice is appreciated!

the new charge port flex doesn’t have this piece of board with it. How do you transfer it over? Can you buy this piece of port separately? What does the board do on the flex? Thanks everyone

So I have this 11PM that has a dead battery (Which is Apple original), no problem I'll replace the battery. After replacing the battery I found that the device turned on but was stuck at 0% and not charging, it would also not show any battery information on 3uTools with the battery value and the ex-factory value both being at N/A, an indication that it is not reading information from the bottom connector.

After checking all the connections I tried a different battery from a different reputable supplier but have exactly the same issue. Both of these batteries give me all of their information on my jc v1s just not in the iPhone and thus although it does turn on it will not charge but it does still detect USB.

I should also note that the iPhone does not draw any current from a wall socket.

Any advice on next steps?

Thank you,

Tom

As the title explains I got the notification stating I had an unknown battery part. I still have the original battery part so I'm unsure why this is popping up. After reviewing battery health it shows it's at "0%" charging and will do a restart after about a minute of it being on. This doesn't provide me a large window to trouble shoot the issue. I have also popped it open and disconnected and reconnected the battery to see if it was a possible cable connection error but the problem remains. Any ideas?

I was given an iPhone 11 pro max and the previous owner said that it was working fine, and the next day the phone wouldn't turn on. it's worth mentioning that some days before, a message from the system popped up a liquid-detection alert but they didn't care. When I got it, I tried making the phone to enter diagnostic mode, tried to do a hard reset but nothing. My mind is really messed up, and I don't know any other possible things to try. The thing I suppose that might cause this whole issue is the charging PCB (because of that alert that the system popped up). Any possible things to try?

Thanks in advance!

So, i have a completely destroyed iPhone 11 Pro Max that i would really like to fix up to avoid it becoming just more e-waste. Question is, i’ve done a bit of research on LCD displays retrofitted onto OLED iPhones and from what i see they usually cause board damage because of more power draw, but i wanted to find out if this magically happens to not be the case with the iFixit display.

Thanks a bunch for all the help!
