Bought an used iPhone 6 with cracked screen. Decided to change the screen myself, since I have done multiple repairs on iPhone 4,4s,5,5s etc. Managed to replace the screen with all the small parts sucessfully.

Now after one day, I noticed a clicking noise on the screen, when pressing the top left corner. Googled it, and came over some people with same issue:

It is easy to see, that the screen is not laying 100% flush with the frame at that point.

Since I have opened my phone, my warranty is gone. Does anybody here have some tips on how to fix it? The youtube video tells me to try to bend it back alittle, which I'm not so happy doing. I think that the screen may crack if I bend it to much. Maybe disconnect the screen and then try to bend the left top corner a little back?

I have an iPhone 6 and the touchscreen will freeze randomly. Sometimes I have to wait five minutes from start up for it to respond. Sometimes it works straight away but only for a few minutes. Sometimes it'll work for twenty minutes. There is no rhyme or reason to it freezing.

Here's what I've tried,

1. Soft resets - didn't help.

2. Factory reset and set up as new device- didn't help

3. Fitting x 3 new known working screens - didn't help

4. Cleaning the connectors with iso alcohol - didnt help

5. Updating software which went fine (no error codes) - didn't help.

Probably helps to mention I've switched the motherboard out of a damaged housing to another genuine housing. I own a small repair business and can strip most parts almost blindfolded.

I can't see any physical damage to the board and if the mobo touch connector were damaged the rogue white lines would appear.

Any advice would be appreciated.

Thanks in advance.

I've replaced a fair few iPhone screens but since iOS 10 it seems that even if I use the original home button I still get the error that the Touch ID Failed. When I go into the settings it does not get past the on / off part, then says failed again when I go to put a fingerprint in.

I've tried hard resets etc. I always unplug the battery when I do the repair. I have not tried flashing the software but as I have many customers come in I'm concerned if thats the case for each repair then I'd lose the repairs altogether.

Any solutions or advise? Has anyone else expierenced this?

Thank you

how do i check the main board is the correct one for the phone if apple haven't included a serial number on the main board and the phone is completely dead?

thanks

Obviously the power and home button work, after measuring I also know that it’s charging. I got the phone from a friend and what I know the screen has been replaced by professional and after that the phone worked for a few months before this it just died one day.

Any idea where to start, NAND maybe?

What I have come to find is that if you are wanting to replace just the battery without removing any of the LCD/Home Button/Front Camera,etc. flex cables DO NOT just unplug the battery with the phone still ON. Unplugging the battery with the flex cables still attached (without even removing the bracket holding the flex cables down) while the phone is ON, then reconnecting a new battery will cause the screen to flicker most of the time, even if its an OEM screen… Id say its about a 80% rate the screen will flicker if using this technique by not powering down the device with the power button and sliding power off.

If you want to replace the battery without removing the flex cables, POWER DOWN the device by holding the power button and sliding power off. Wait around 10 seconds (or the amount of time it takes you to unscrew the bottom screws & battery screws). 100% of the time I use this technique I have had 0 screens flicker.

I have tested both techniques with over 50+ phones over the past 2 days. All using the same replacement battery from the same vendor.

It does not matter if the screen is OEM or aftermarket. You will get a flicker MOST likely if you use the first technique I explained. Some iPhones did have an exception where the screen did not flicker when I disconnected the battery with the phone still ON.

I do not know the ins & outs as to why this is the case but I have found of this will cause your screen to flicker in the 6 & 6s.

I have not tried any other models yet as I am only refurbing i6 or i6s batteries currently.

Just thought Id throw this information out there to save the anxiety for people if this ever happens to them.

From what Ive read the flickering should go away after hours of leaving the devices on but I am unable to test that part since I pass the phones on once refurbished.

So if you want to avoid your screens flickering. POWER THE DEVICE OFF USING THE POWER BUTTON & SLIDE POWER OFF & Be patient.

My iPhone 6 was in a pool for about 2-5 minutes, I cant fully remember. I did try to turn it on about 1 million times (I know it wasn't good idea I was just freaking out).

About 15 hours later I took the screen off fully and put that and the rest under rice and silica packets (I know its more of a placebo than actually working.)

After being under rice for about 4 days I put it back together and it still doesn't turn on.

So to my question, is there anyway I can search through my phone to see what new parts I might need to buy and replace or should I just cut my losses and leave the phone.

So what have I done?

I just disconnected my old battery and LCD, after that without any phone damaging I finished my job and turned it on and I got message that touch ID is not working.

OK - I have dissasembled my phone again, reconnected all connectors and turned the phone and voila - touch ID is working.

But thats not the end, after that I wanted to check again, is there isnt any problems inside. And what do you think, after that its not working again.

So whats the problem? I didnt damaged anything (I hope so) and it have worked once after battery replacement

i had a problem in my phone after it got dropped , it's turning on and showing apple logo for 10 sec , then black screen and stays black

when in black screen i can see that there is light in the screen from back , means it's working but nothing appears in the screen

so i went to a local Maintenance store , he said he will change the power IC , and sometimes data will be lost , and sometimes it will stay

is it true ? because i don't want to lose my data

I am just wondering if phone is even repairable if it got really hot that first day, as I am not sure what that was.

None of these issues occur when I play music from the iPhone out loud (without anything plugged in the auxiliary port) although the sound is a little gargled (my speakers are sub-par, also might be due to water damage or some other cause).

Does anyone know what might be causing these bizarre glitches? And are there any replacements/repairs possible or do I need a new device?

⟐ Answered 4월 21, 2021 at 7:02 GMT-7

I've tried re-seating the connectors to the display and home button several times. They all look fine, not damaged.

I also tried wiping the phone, but that didn't work either.

Does anybody have any suggestions? I have another phone, a 6s that I'm going to do next, and I don't want to have the same issue.

⟐ Commented 2월 10, 2021 at 1:59 GMT-7

The tools necessary to replace the battery will take around a month to arrive. Do you guys think I have that long, or is the battery likely to expand enough to split my phone completely open and/or cause severe damage to my screen?

⟐ Commented 1월 16, 2021 at 18:16 GMT-7

The microphone of front camera is not working. I know most of the time this issue is resolved by changing the front camera flex cable. The weird part is that even after changing the flex cable from other iphone 6, the problem continues. Also, if I use the entire screen from this phone (along with all the components attached such as camera, mic etc) on other phone the front camera microphone works. Does it have to do anything with logic board or any other parts? Any help is appreciated.

Thanks in advance!!

Installing the new screen went great. But I noticed that the screen brightness wouldn't adjust automatically after that. I tried everything I could find online, from re-calibrating the brightness sensor, to turn the feature off, and soft reset the phone. I did not try to reset all my settings because that's what I'd like to keep.

Does anyone has a new idea?

I don't mind opening the phone up again to solve it.

After replacing my iphone 6 (no plus) screen, the flash stopped working. It does not work either in torch mode or in photo / video mode.

The rear camera works well.

When the torch button is pressed, the flash flashes for a few moments, as in this video (https://www.youtube.com/watch?v=KqxVgYUj...).

I recently replaced the flash but still have the same problem.

Solutions?

Thanks in advance.
