Hi.

I have noticed with my iPhone 7 that it I turn it off and then plug it into the charge instead of turning back on like all apple devices it shows this battery icon (see picture) which I have never seen on any of my apple products. If I then hold the power button it turns on. I also noticed that in settings Wifi is called “WLAN” and has some strange settings I have not seen on my other iPhone 7. Henceforth whenever I open a app it asks me if I want to use only WLAN or WLAN AND WIFI with the app. I checked all the serial numbers and it is all legit and everything else is identical to my other iPhone 7 so it is a real iPhone.

any ideas?

cheers

I was replacing battery on my IP7. I disconnected battery at first then screen and then camera with sensors, unfortunately after replacing battery and connecting flex cabels, I somehow ripped a front camera and sensors flex. I realized that after assembling phone and turning it on while home button stopped working. I was like what is that , I was super careful, so i looked into phone whats wrong and noticed that ripped cabel… howover i checked display cable and home buttone cable too and it seems untouched. After replacement I ´m getting message “Unable to activate Touch ID on this iphone”. Do someone know if I will replace that flex, it is possible to get it working ? Maybe better, working with TouchID funcionality ?

i have tried testing if the phone still has power by charging it and flipping the vibrator switch, no signs of life. I then tried to connect it to my computer. Still no sign of life! How can I check if the phones alright?

do I need to have the screen with the flex cables to let the iPhone 7 power on? Thanks.

TL;DR

After changing battery and front speaker, the iPhone only boots normally when either the front camera assembly (old or new) or the home button (old or new) or both are disconnected.

Long Version

I’ll start chronologically and tell you step by step what I have done, so that you can maybe spot the problem.

I recently had problems hearing my partners on calls. I suspected too much dust on the speaker, so I decided to thoroughly clean it. Since I had to open my phone anyways and the battery had only 80% of its original capacity, I also decided to change the battery as well.

Before I started I updated my device to iOS 13.5. Opening the device I had a hard time to to get the spudger initially between display assembly and lower case. I had to pull really hard on the suction cap I put on the lower part of the screen, despite I had warmed the glue with a heat gun set to 100ºC (212ºF). The I disconnected to battery connector, then the display, home button and front camera assembly connectors. I then removed the top speaker from the front camera assembly so I could clean all the dust which had been accumulated during the years (it was a lot). I cleaned it by carefully blowing the wire frame out with compressed air and wiping it with a q-tip and isopropanol. Then I put the speaker back in place, changed the battery and connected everything back to the logicboard (power cable last).

When I tried to start the device it got stuck in a boot loop. It showed the apple logo, then the screen turned to black and the iphone rebooted.

• First thing I tried was putting the iPhone in DFU mode and resetting the firmware. No success, nothing changed.
• Then I read that a faulty front-camera or proximity sensor could be the case (maybe I had damaged it with the compressed air). So I changed the front camera assembly to a new one. No success, nothing changed.
• Then I tried changing the front speaker to a new one. No success, nothing changed.
• Then I tried removing the connector of the front camera assembly from the logic board. Now the iPhone started, but the home button was not working anymore.
• Then I kept the display assembly disconnected and removed the home button connector from the logic board as well. Now the iPhone started, but the home button was not working anymore (since it wasn’t plugged in anymore).
• Then I left the home button unplugged and reconnected the front camera assembly. The iPhone booted normally. Front camera, front speaker, ambient light sensor and proximity sensor were working (Have tested all of them). And the home button of course was still not working since it wasn’t plugged in.
• When I connected the home button back to the logic board the iPhone was stuck again in boot loop.
• Then I disconnected the home button again, this time I left the home button connector on the logic board plugged in and just disconnected the home button on the backside of the display. The iPhone is booting again normally, but now home button (since it was not connected anymore).
• Edit 2020-05-26: I’ve now also tried a new home button. As soon as any home button is connected the boot loop appears.

So the iPhone only boots normally when either the front camera assembly or the home button or both are disconnected.

I don’t suspect the front camera assembly to be broken, since I’ve tried two of them, both resulted in the same error and when it was connected while the home button was disconnected all sensors where working properly.

I also don’t suspect the connectors on the logic board or flex cables to be broken or having a short, since the iPhone is booting when all of them (but the home button connector on the backside of the screen) are connected.

Where do you think could be the error? What am I missing out? What could I try next?

i Tried updatint to the latest iOS, restoring the whole phone, reset network settings. Everything. So i am 99.99% Sure it ain't a software issue.

Anyone has a idea how i should start searching hardware issues? I heard the wifi antenna cannot be changed, cuz the ic on it is paired with the cpu. is this true?

I have one iPhone 7 which was waterdamaged, but I returned it to life by using isopropyl alcohol and ultrasonic machine. The problem now is the fpc connector which the pins was broken. I ordered a new one to get them replaced, but when I removed the old one, I saw many missing pads. Any suggestions what to do? If those all needs to be do with jumper wires for me that will be a very hard job. Something else suggestion?

i am having a problem on my iPhone 7 where occasionally they wifi icon will be grayed out in control centre and settings. From my research this seems to be a hardware problem but I’m not sure which part needs to be replaced exactly. I’ve attached a screenshot of some of the options that come up for antenna replacement on amazon. Any help is greatly appreciated. Thanks!
