iPhone 7: iPhone 7 stuck in Boot loop after shorting Display plug pins

Sat, 14 Jul 2018 08:28:07 -0700

I really hope someone can help.

I recently fitted a new screen to a iPhone 7 but upon start up the phone got to the apple logo and then restarted again. After searching the threads I thought it could be the audio ic which I tried to reball but there was no change so I put the phone aside.

Today I had another iPhone 7 and thought I could use the new screen however, the same thing happened with this second phone i.e bootloop ( the phones restore normally but then revert to a boot loop )

I had a look at the screen cable under the microscope and found a bit of solder touching ground and the top four pins ( I think they go to pins 1,2,3 and 4 on the motherboard )

I have checked the board and discovered at least pin 2 is short to ground which the schematics show as "I2C_Disp_EEprom_SDA_Conn"

I have checked FL4741, C4741, C4731 and FL4729 and all are shorted.

Can someone please help and give me some idea where the short is possibly coming from as I have two customers iPhone 7's to repair.

Thank you in advance

iPhone 7: iPhone 7 Touch ID doesn't work

Fri, 17 May 2019 08:14:50 -0700

Hey guys,

I've replaced an iPhone 7 Display (refurbished, original LCD), but after I powered the iPhone on, I couldn't add a fingerprint anymore.

The fault indication (that Touch ID has a failure) does not appear in the homescreen, but appears if I try to add a new fingerprint.

Homebutton (still the original one) and 3D are working without any problems.

Thanks in advance for your help.

iPhone 7: Ear speaker doesn't work after changing display

Fri, 06 Jul 2018 16:42:33 -0700

Hi guys, i've replaced my iPhone's display, everything works well but the ear speaker, when i'm on the phone the display turns off, so the proximity sensor works, even the front camera works, but not the speaker... i've moved all the parts from the old display to the new one, even the little piece with 4 gold dots.

iPhone 7: Cellular data does not reconnect after being in dead zone.

Thu, 05 Jul 2018 09:08:31 -0700

My cellular data does not reconnect if I've been in a dead zone. I then have to turn airplane mode on for about 10 seconds, then turn it off, in order to reconnect to cellular data.

Since I work in a factory, this happens a few times an hour and it is very annoying.

Anyone every experience this or know why it happens?

Mon, 13 May 2019 20:38:05 -0700

Hi,

I have an iPhone 7 which is blocking in bootloop. I tried to open it, check if connectors are good, but the flex of the charger port seems to be a little bit bent.

But, the PC doesn't recognize the iPhone, the phone is not recognized by iTunes or Dr. Fone so I can't restore it.

iPhone 7: Am I the only one experiencing problems with parts from here?

Sat, 10 Mar 2018 21:48:29 -0700

I'm not dissing on anyone or anything. I am trying to figure this out because I know I can have bad luck in everyday life, but really never in parts or repair. As of late, it seems like I'm having issues with iFixit parts. The main problem is an iPhone 7 that I am having problems with. Originally I put a new screen on it in December I believe. It was fine until about 2 weeks ago where the owner reported the left side of the screen stopped working to the point that it went black with a line being the only thing visible. There is no damage that can be seen or anything. It had a tempered glass and if there was damage caused by the owner, I would think it would of shown on that too. No problem. I order a aftermarket screen assembly, do a warranty claim on the old screen and install the new one I installed. The newer screen looked fine and worked will. However that didn't last long. Before putting it back together, I let it sit for 5 minutes or so. That is when it started to show a flickering white ring around the edge of the screen. It went away after using the phone for a bit but soon enough it would come back. Well maybe it was defective. So I did a warranty claim on both screens. I got the new ones. This is where I am wondering what is going on. I tried the first of the newer screens. All seemed well. I let it sit for like 30 seconds and that is when a white rectangular section on the middle of the screen starts appearing. The more it sit, it comes up fully. There is no way I thought. I then try to use the second of the the two that I was sent. Same story though but different result. Everything was fine. Let it sit and now it shows the middle rectangular section with spilt regulars going up and down and the flickering white ring around the edges from before. In all of these attempts I disconnected, clean off the connectors in how iFixit recommended me before, then reconnected and put the bracket to be sure they weren't going lose or anything. But the results would be the same. I haven't denied it couldn't be the phone. But I asked a friend to let me use their iPhone 7 to try their screen. It is the original Apple screen and even after letting it sit for awhile, it all worked fine. So that is kinda telling me that it's not the phone and more then likely the screens. I know they aren't the choice version but I wouldn't expect that from here even for cheaper versions. Should I go ahead and try the choice version and see what happens or is someone else having problems and I'm just lost in what to do?

iPhone 7: Someome please help. Can replacing my screen fix this?

Sun, 18 Feb 2018 11:59:34 -0700

My screen randomly started getting these black and colored lines across it... It started on right side and slowly spreading across the screen throughout the day. My screen has been cracked for more than a few months now. But the screen issue just started.. The touch screen doesn't work where the lines are but works where they aren't on left.

I have to carry my work cell IPhone 5S and personal cell I phone 7. I am looking for one head set that could pair to both so I can answer which ever is ringing.

iPhone 7: digitizer only works when touching frame

Thu, 07 Dec 2017 20:09:11 -0700

Hello, I have fixed hundreds of phones and after replacing the first time Screen on and Iphone 7, I noticed the digitizer works great but you have to be holding the phone. If you put the phone down and try to use the digitizer, it will not work.

If I have the phone on a table and touch the metal frame it will work but only touching the glass the digitizer doesn’t respond.

I a guessing it is a ground issue, but was wondering if anyone else has a solution.

Thank you
