iPhone 7: No audio recording, voice memo recording button unavailable.

Tue, 18 Dec 2018 22:08:06 -0700

Customer claims that pre-iOS 12 the device still wouldn’t record audio, and updated in hopes of fixing it. Still no dice, any ideas?

The phone records video just fine, but there is a complete lack of audio. (I tried using third party apps, the external mic on headphones, the whole sha-bang.) As for voice memos, the record option is quite simply grayed out and unavailable. Is it a chip issue on the board, or?

iPhone 7: iPhone 7 No front camera plastic holder/bracket/clip in replacement

Tue, 29 May 2018 12:53:50 -0700

Hi all,

I'm currently in the process of replacing the screen on my Iphone 7. Starting to reassemble the front camera and noticed that the replacement screen doesn't have the two plastic holders/brackets for the front camera and proximity sensor (see link) like my old screen does. Is this going to be a problem? Is it possible to transfer them over from the old screen (they seem to be stuck on there pretty tightly...)? If I have to purchase these how do I attach them, would an adhesive of some kind be necessary?

Thanks in advance

In case you don't know which parts I mean!

iPhone 7: So, any update on replacing displays?

Sat, 18 Feb 2017 15:11:17 -0700

Last I checked, about a week ago. Everyone here is saying there are errors with iPhone 7/7+. After a third party display replacement. Mostly with the home button. Which I noticed quite a few articles saying the home button messes up anyways. Also I noticed cpr saying their more than happy to do these repairs. I've been turning away and cautioning customers. Has anything changed?

Wed, 06 May 2026 06:09:28 -0700

I have a iPhone 7 I’m dealing with an iCloud lock the locks stored on the board from what I know so does replacing a logic board bypass the iCloud lock fully i have a logic board that’s fully unlocked I just need to know how to replace it and how to reinstall the adhesive that goes around the screen

The story is I got this from a friend who has no access to it he says it’s fully functioning and wiped it’s just he cannot access it due to lack of proof that he purchased it he heard about me and how I fix old phones and tablets and says if I fix it I can keep it as he already has the 12 so I’m asking here for help

(I added this for information I told apple what I told you they like aways said that it’s unfixable and it’s better off I dump it and get a new one)

Thanks for the help appreciated

iPhone 7: Unable to Activate "An update is required to activate your iPhone"

Thu, 21 Mar 2024 16:36:20 -0700

I just got this iPhone 7 to repair. It was boot looping, so I put in a different battery. It was still boot looping, so I put it in recovery mode and plugged it into my computer and updated it. I eventually got to the iPhone Unavailable screen, so I put it back in recovery mode and restored it. It went to the usual "hello" screen and I got to the part where the it tries to activate, and all it says is "Unable to Activate an update is required to activate your iPhone. Learn more at apple.com/support"

I already updated it, so this error isn't making sense to me... Could this be an issue with the carrier or a hardware issue? I had another iPhone 7 previously that had a damaged chip that made it so that you couldn't connect to cellular or activate the device. Could that be the issue here? Or is it simply iCloud locked?

Thank you for the help!

iPhone 7: iPhone 7 dead after removing Baseband CPU

Tue, 18 Jul 2023 21:08:03 -0700

Hi guys, I have a dead iPhone 7 here. It was repaired by other shop before coming to me. It was a poor repair by someone. They tried to remove the audio chip but failed. I can see they used lot of heat trying to remove the audio chip and shorted it underneath. Knowing the cause of the short, I swiftly removed the audio chip, now the short was gone, the phone was able to turn on without any issue, however, I noticed the baseband was gone, there is no firmware in settings . I guess the baseband was somehow disturbed in the previous failed repair. There is no option left but to remove and reball the baseband CPU. I successfully removed the baseband CPU and without pulling any pads. However, the phone won’t turn on. :(

My question is, will an iPhone 7 turn on without a baseband CPU? I know iPhone 6 series can turn on without a baseband, but I am not sure on iPhone 7.

iPhone 7: iPhone 7 doesn't turn on after replacing battery, screen and dockconn.

Mon, 01 May 2023 04:37:21 -0700

I have an old iPhone 7 that has been laying around for quite a while. Since there's still some data on the phone that i'd like to retrieve i tried fixing the phone a couple of times. In the process of tinkering around for fun i broke the screen and the battery cables. So i decided to buy a new battery, a new screen and a new dock connector. I replaced those parts a couple of days ago.

Now, however, the phone doesn't turn on at all. When i press the power button nothing happens; when i connect the phone to the charger, nothing happens either. I thought i had replaced all the broken parts, but perhaps the logic board itself is broken? If so, how could i check this?

Thanks in advance!

iPhone 7: iPhone 7 earphones & call not working

Tue, 20 Jul 2021 23:54:01 -0700

Hello. My iPhone 7 only plays music out of the speaker when I plug in my headphones. It plays music normally when there are no earphones plugged in. Also, when I call someone I cannot hear them and they cannot hear me. On a phone call, the speaker button is dulled out, so I cannot click it. I’ve tried different earphones, cleaning the earphone socket out, and restarting my phone, and nothing works. Water may have gotten into my iphone at some point before it stopped working and I’m thinking that may have something to do with it. Please help!!!

iPhone 7: iPhone 7 keeps restarting and does not show battery health

Wed, 21 Apr 2021 16:21:17 -0700

I was given iPhone 7 32GB for free and it had screen smashed. So I changed the screen and while I opened it, I changed battery too. When I started using the phone, it always restarted when trying to log in to my Apple ID or updating the phone. Battery did recharge to 100% ok. Yet, phone does not show battery health and keeps searching it.

So I thought maybe the battery is faulty. I changed again a new battery and phone keeps restarting if I try to log in to my Apple ID or update it. Battery does not show health and this time it won’t charge more that 27%.

All I can do is perhaps change a charging port. I don’t know the history of the phone and I don’t know how to check or fix problems on board.

Any advises or should I just toss this to trash bin?

iPhone 7: wifi greyed out, but works after some time after booting

Sat, 07 Dec 2019 06:47:20 -0700

A customer sent us a phone with audio IC problems. I noticed wifi is greyed out as well, so I checked info in the settings menu. It lagged and didn’t enter the info page, which is an indication there are problems with the wifi chip. Read this on a forum.

After a few minutes, wifi will work but will be bugged. The phone says the wifi is off while it’s on.

When I restart the iphone wifi is greyed out again. Does anyone have experience with this? The second phone in 2 weeks that have this problem. First time the customer came back and saying her wifi was broken again. I reset the network settings and it worked the first time so I didn’t read too much into it and didn’t charge her money.

Sounds like a wifi chip problem, but I wanna make sure. Repairing the audio IC isn’t an issue but I don’t wanna make things worse after heating up the board when repairing audio IC.

EDIT: Just repaired the audio IC and left it like that. The customer is aware wifi can fail any moment but didn’t want to pay for the repair. Can’t do anything else than that.
