iPhone 7 Audio IC Replacement - Loop Disease Fix

- čas přidán 12. 09. 2024
- This is an iPhone 7 with what is being called "loop disease." The term ins unfortunate since your phone will not necessarily exhibit boot loop but in most cases boot up time will be significantly long and the record button in voice memo application will not be functional.
We fix this problem regularly. For a quote visit gocellphonerep...
What I’d like to know is WHY, as it did with me, why did this anomaly seem to happen to so many people after an update.
Did you update during an eclipse?
It takes longer but doing all 4 jumpers will prevent warranty come backs, believe me just had one that I did 6 months ago come back and it was one of the 3 pads I was not doing the jumpers on at that time. Great video by the way very in depth and well done!!
Thank you. Were the symptoms the same on the one that came back? I coulda sworn Jessa Jones made a video where she disconnected the other three and everything still worked. Is it possible that the C12 jumper failed? Really curious because initially I was doing all four and that changed my mind but yeah, don't wanna have to worry about these coming back.
It was a little different in that the voice memo was not greyed out but it took forever to boot. My understanding is 2 of the other 3 are looked for during boot and even though they do not fail nearly as much as C12 but it happens. On this particular phone the 3rd pad with a trace came up while I was tinning the pads after IC removal so that was a direct indicator it was my problem.
Watching this on an iPhone 7 :)))
(iOS 13.7, no audio problems to this moment). 2 years of use, i tend to avoid putting the phone into the pocket or elsewhere where it could potentially bend a bit, so i guess that is why it still works
Good day, I have an iPhone and the earpiece auto keeps going out and I have to restart the phone for it to work back. can you fix that issue
Have you tried using solder paste that is somewhat dried out? People have reported using drier paste prevents balls from popping out to to the flux that is already in the paste. It also means that applying the past you are actually adding more solder rather than flux.
I've experimented a bit with more and less flux but always using the same paste. It's the Mechanic XG-50 type. It's always in the fridge to prevent oxidation so how would you recommend going about drying it out? Or is there a different type that I should try? For the most part it works well for me especially now that I know how much flux to add and of course the 3D stencil but always open to trying different methods.
Great video, but I don’t quite understand why the jumper was needed. I thought the issue was only with the solder pads?
better safe then sry type thing, the traces have a bad problem of failing
To ensure that the issue does not happen again
Is it possible to just replace the whole audio ic assembly with a new one instead of soldering the chip?
Tim Bronson
No, it’s connected to the logic board by solder so the only way to do it without soldering is to replace the whole logic board which is pretty expensive.
Now you need to fix Siri lol. She can't read!
She can’t do so many simple things it baffles me. Take a picture? Nope. Tell time? Nope. Answer a question? Nah I’ll just bring up a google search instead. Okay thanks but I can do that myself with the same amount of effort. Some future update I hope.
Applying flux when removing a chip will definitely help solder to melt faster, good job
This just happened to my 7 last week, I'm actually surprised my phone has made it this far, I did drop it once off the roof of my house at least 27 ft down, but it ran down the roof line then off the gutter and fell the remaining 19 feet to concrete. OTTER Box saved it....
Can u share me d link of jumper wire which u used in d video thanks in advance
Mechanical 0.01mm wire
When repairing the iPhone 7 audio chip, do I need to reconnect the jumper wires? It seems like a difficult task, and I wonder why the connection is necessary. I'm trying to DIY at home, but it looks difficult.
The most common source of audio IC issues is that there is a fault causing the C12 pad to become disconnected from the audio codec circuit. Without adding the jumper wire, you will most likely not be addressing the problem. FTR, I have never added any other jumpers outside of C12 and after hundreds of Audio IC repairs, none have returned with any audio related issues.
I’m having this problem on my Iphome XR after I got the screen fixed , I can’t hear anyone on the phone but everything else like music works great , I think they have Nicked the Audio IC cause I can’t hear anything or anybody when I’m taking a call, but when I do voice memos the button isn’t grayed out I can still record but can’t hear anything
where are you located at? my daughter's iphone 7 audio is not working, can't make and answer calls, siri not working, speaker button is greyed out, video recording can't record, ect. went to Apple store and tells us it costs $300 to fix! Or they want us to buy upgrade phone.
I am in the East San Francisco Bay Area. Just sent you an email.
Go Cell Phone Repair can you send me a message as well. Interested in a repair and in Walnut Creek.
How do you orient that IC chip? To me it looks like a square with no position indicators. Does it matter what way it goes on or is there a specific side the goes in a specific direction?
Just line it up so that all sides are equidistant to the neighboring components
Under the microscope you can see some written words on the audio chip. Often you cannot see with naked eye. This is how I know the correct direction of the chip when I place it back on the board.
What type of wire(size) was used for the jumper?
Hello! Why are you soldering the jumper? Is the pad damaged? Unfortunately i cannot see in the video with the light setup! Regards
That pad is part of the manufacturing defect that causes this audio problem. The jumper is a fail safe so that when the pad lifts up off of the board, and they eventually do, it will still have a point of contact to the resistor.
@@GoCellPhoneRepair Thank you for the answer! I was about to repair the Audio IC and the phone is not even turning on... the root cause can be also the audio IC or may be other thing??
ESIM chip st33g1m2. There is no data when replacing a new chip. How can we use it normally
is this the big or little IC chip ?
Very impressive and educational video. Thanks for sharing your knowledge
Hi bro, in my poco f1 if i call anyone opposite person is hearing there voice back as echo in high level but i can hear there voice clearly without echo, when i reduce my speaker volume then they will feel that echo is bit lower and when i muted they will not here any echo issue.... I have tried changing the mic as well but no luck please suggest something to resolve the issue
Hey Mike! It's been awhile since we chatted. Hope you are well. I acquired an iPhone 7 with this exact issue. I lost your contact info so I haven't been able to get a hold of you for a price quote to fix it. I still don't have the tools to do this stuff myself unfortunately. If you could let me know a good number to call you at I'll contact you soon. Take care buddy!
Just emailed you.
Sir ..my iphone 7 's mic and ear speaker not working ..it works for 30 minuts when i restart my phone and then again stop working..what i shuld do??
Good job . I like it
Thank you
You dont clean the pads with soldering wick??
I don't. They are about to fall off as is. As long as you remove oxidation and level them out they'll bond just fine.
Would Apple replace it?
Got the exact issue no warranty though
Sagar Verma no
Apple don't admit their flows
Hello . Can you tell me please wich iphones are affected by loop disease ?
Also , which model has a longer lasting battery in time ?
i cant turn on my iphone after change audio ic,help me
wecanfix temm | Did you solve your problems?
Where ARE YOU ON THE PHONE THESE VIDEOS DON"T SHORE ME EXACTLY WHERE TO GO
What? Stop yelling so we can hear you.
are you using a preheater for this?
Not necessary
How much you charge
Temp?
he mentioned that it is 370 for remove the chip but it is depend on your preference and how skilled you are i don't look at temp when i do repair jobs
How much for this repair?
FishOn916 $100 on his website
Wait how much to repair the loop disease
£50-60
How hot is your tip
Where can someone get flux for the repair
amazon
where do i get this "jumpers"
use any conductive wire 0.02 or 0.01 diameter
Where are you from?!
California East San Francisco Bay Area.
Sure fire way to cause a baseband issue!
In my experience there is considerable risk when working with an A1660. For that reason I prefer not to service that model unless the customer is okay with accepting the potential outcome. In the end they might still be able to get something through Apple if that is the case. On the other hand you can sometimes reball/replace the BB PMU and get modem firmware back. As far as other models go- so far so good. I've done 200+ without issue.
Is anyone-hopefully with a helpful answer-still here? Can the audio IC from an iPhone 6s be put in the iPhone 7 to fix this? Thanks!
No, they are different sizes. The one for the 6s is much smaller
yes iPhone 6s and 6s plus work fine for iPhone 7 and 7 plus
I have the iPhone 7 Plus btw
IMAINWIDOW no one asked but ok
Does anybody know how much they charge to do this repair at the Apple Store?
Apple is not equipped to do this in their stores. You can see if they will swap you out for a refurbished phone (maybe maybe not) but outside of screen and battery replacement Apple stores don’t really do repairs.
Thank you!
Lazy working..... 😂
Why you don't clean all pads and IC with wick, to remuve old solder but you just mix them!??
When reball I never put/mix flux with solder paste in stencil, and need to make 4 jumper not one, to have life time warranty 😁
Thanks for the comment. I am interested in hearing how you have come to these conclusions.
Outside of concern for oxidation- which should be eliminated with fresh flux and heat- why are you concerned about leaving the original solder in place? These joints are not under stress as would be something like a charge port so to my knowledge evening them out is more sufficient and acceptable.
Wicking in this situation is totally unnecessary according to most professionals and I would tend to agree.
When I reball I always use a small amount of flux in the stencil as it allows for easy removal. Is there a reason you know of that makes this problematic?
As far as the additional jumpers I realize that this is a point of contention within the microsoldering field but based on my experience with a couple hundred iPhone 7 and 7 Plus audio IC repairs I've had only one that needed an extra jumper on J12 and that was because another shop tried to repair the phone and ripped the pad off of the board. Is it possible that you are doing a lot of extra work? So far no problems/redos here over a two year period.
I gave up and traded it in for xr
For how much and how
What about the search 🤪🤪
proteknik apple servis
Just get a new logic board from AliExpress
