Sorin I prefer you in the wig and long nails 😂
I got the same problem it comes back after few months i think the person who first fix it use this method , decided to repair it again today , i think for long term replace the audio ac
Congrats on the video, but sadly this repair needs a bit more work to last... we have a video on our channel where we show the full process of fixing this issue for good: th-cam.com/video/kPLyjR_Au4U/w-d-xo.html

Should be able to reaball existing chip and run c12 jumper. Just replacing it will have a repeat fail due to stress fractures.
Isn't this related to the known issue in iPhone7s where there is a flex issue with the phone along side of the SIM tray right where the Audio IC is located? It creates a solder connection on pad C12 on the audio to a nearby cap to fail. Soldering a jumper from this pad to the CAP solves audio issue with voice memos etc.
i dont really know, the phone had no lag.
Ya usually will notice a slow boot up when the C15 issue occurs or people not hearing you on cell call. Not being able to record or play back any voice memos is an indication a jumper may be required. I guess thats is the result of having " thinnest and lightest" iPhone yet design or heaven forbid people putting phones in their pockets.
What temperature is your hot air set to?
Hello, I got an iPhone 6 that was dropped in water. The sound is intermittent. I tried to replace the speaker but the problem persist. Any idea what I should check on the MB? Audio in calls and through earphones is fine
you need a schematic to find out where is the audio amplifier ic
Electronics repair school ok thanks
Thanks for the link. Another great video showing that it doesn't matter what is given to you it's a structured approach and repair. Keep them coming.
I just did this on my iphone 7 and I think it worked since my boot times are normal now but now im getting a "cellular update failed" notification. I don't know what I did wrong. Anyone have any ideas?
Just checked voice memos, The mic is working now but I can not use it for calls :/
@@AmazingCodCasting did you fix it?
Ocean iPhone Repair (by Appointment Only) unfortunately no. It just got worse. The motherboard started to over heat and it stopped turning on afterwards. Just sold the phone for parts. TBH, this was way above what I am comfortable with but a good learning experience.
What liquid did you put?
Careful of the baseband on otherside mate 😎
Thanks for yet another great video, I have learned so much from your videos.~ You should try reflow on your gopro.....lol
Thank again.....
You think the main issue was because the cell got too hot overtime, maybe placing a small amount of copper tape can fix the issue permanent after you reflow it. ? Awesome videos. Thanks for sharing. Keep up the great work.
yes, that what i'm thinking! Maybe a small piece of thermal pad will solve the issue
why you not sort all the screws in order? every single retainer plate has different sized screws...
Trick is work on my iPhone 7 😂🙏🏻
You are a great technician... Many videos on extract, reball, cut here and cut there, do jump.... You simply did what is enough to fix the problem, and it was great. I still don't understand how you can put screws that were not in order, how you do it? What is the secret? I lose a lot of time to put it in order, so that i don't make mistakes when i reassemble everything.
I am new in the field of repair and I encounter a problem with two iphone 7 who have the same problem,
problem ic speaker, after changing the ic cpeaker, work well done on both but I encounter the following problems:
1 - phone reboot every two minutes
2 - when the phone turns on the battery is 1% (battery charged)
3 - when I plug in the charger the battery indicates a percentage and when I unplug the charger it indicates another percentage
I put you in attachment the video

thank you for your support
enjoy your holiday sir.
Hello, i’m just starting with soldering and have set the temperature at 370 degrees but the chip isn’t moving 😁. Do You have to place the end of the gun against the chip of just above? Or if somebody has other tips then please let me know. Thanks very much.
Excellent job. Worked for my iphone 7. Thank You so much for making this video.
I have this same problem and I took it to Apple to see if they could fix it and they told me it wasn’t repairable and I have to get a upgrade or a new phone
I fixed mine doing what he did
Kudos to you mate I just fixed mine doing what you did and I have no experience what so ever in doing these things. Mine didn’t move like yours did but I believe I got it hot enough and place a little pressure so the ic board can connect more I guess and well it works my mic and calls work now thanks to you. All the other videos had you removing it and adding copper to this part and that part and you made it simple thank you for that.
Smashing, phone working with a reflow :-D
Didi's reflow worked perfect too :-D
No new chips required :-)
Wats a reflow?
Sorin. I’m going too buy you a mag tray for your screws lol
God bless u sir
Hi after audio ic replacement iphone 7 is not turning on...any idea why or what can I do ?
Whenever i see same problem foxed by you very easy and i followed same steps never worked.... Seems like need some magic touch from you...
Fan of your videos but this will come back you need to run jumpers to fix permanently
Do you have link to buy thermal pad at 10:50 ? thanks for videos sorin.
ThEwAvEsHaPa you can find them in plasma TVs and many tv that the cpu gets hot
I have loads of them here
thanks i will have a look
ThEwAvEsHaPa I don't know where about you are but if you can get hold of a smashed Samsung plasma you will find them under the x sustain and y sustain boards if you can't get any let me know

Hello , thank you for this good videos , I learning about electronic , computer mainbord repair and phone repair with you . Also I am sorry bad English
Mr. Sorin can you tell me , who is the good sellers for i phone ic parts ,
I need to get some chips from ebay ,
If you can tell me few good sellers ebay or ali express
Three Adds in a 15 minute video...WTF!
Boss please me a video how to used hot air station with ic chip air and hot control because iphone board are both side components
also, when reballing BGA chips, lead-bearing solder has much higher stress tolerances and is more flexible.
sorin,i'm enjoying so much your videos and learning also.keep up your good work
I broke it while doing it, the audio ic did not come off, the transistors around it did lol. Who can give me the golden tip? How much airflow and degrees i need to use?
temperature is like 370 degree , and used flux is AMTEC NC-559 but i really don't know the air flow but i suggest you to use 5 to 6
Great Video On iPhone Repair. It's nice to see a good POV to further my knowledge

thank u soo much ,,for making these videos ,,,I do not want to bother u ,,,but I have question about my lenovo b570e ,,it power on and the fan spin but nothing on the acreen ,I followed your video ,,and checked all the voltages ,,,I have the 19 v ,,,and 3'5v in the bios ,,,I have checked the board behind the acreen ,,I did not see the 3v for lcd enable ,,and also no 3 v for the pin beside it ,,,I swaped the ram ,I reset the bios still no display on the screen ,,, and this laptop does not have a gpu ,,t reflow ,,,so plz advice me what I must do next
reflash the bios just in case but back it up 1st.
if CPU soldered then you need an oscilloscope to see if CPU its active on the memory module.
if the CPu the memory doesn`t start.
You’re great. Thank you.
which paste you use for hot this ic
it's AMTEC NC559
Where are you man.. We miss you
Sudheer M.S holiday :p
This is a good one .
I had a iPhone gyroscope problem can i reflow this too ?
MrRvdbeek ja kan je reflowen 410grade voor 1 minut en .35 seconden minuten ik geb
Ik gebruik zelf de jbc jtse hot air station maar tempratuur verschilt per hot air
privee prive
Oké dank je voor de info
Ik heb deze naar Apple gestuurd en geeft een nieuwe iPhone dus ik dacht dat het risico te groot was om te reflowen.
Oké dan ga ik dit eens proberen met de iPhone 6s die heeft ook dit probleem
1 time perfect!!!!!!!
good job
Good job! 👍🏼
:-)))
i just brushed the speaker and now sound is coming. thsnks for amazing tutorial though. dont forget to checkout my content and leave a feedback
how is it that no one worked on that when then first thing i noticed is that there was no adhesive or waterproofing?
Can apple do this?
Congelou a imagem e não mostrou tudo acho que trocou a placa por outra pra dizer que foi bem sucedido, so minha opinião posso está errado, parabéns pelo canal.
This is a really nice method. But when I use it sometimes I get mono sound out of both speakers. And it doesn't seem to be loud at all. There is sound but not good enough. Do you guys have a solution?
Bit of an amatuer really. Did'nt even switch the phone off before he started taking it apart.
Working on what looks like a concrete slab, not ideal if you drop the phone on it.
Also does'nt appear to be using any antistatic precautions. Schoolboy errors.
Stuart Bassett you are full of crap
You are a dumbass Stuart Bassett
