Hi guys. I recently broke my screen on my one and i order a replacement for it. I decided to do the repair myself and everything went well but when I powered on the phone after i had replaced the screen i noticed that the camera, the upper speaker and the headphone jack weren't working. They are all related to the sister board but i can't find what i have done wrong. I have already checked the connections and i flashed a new rom just in case it was a software problem. Can anyone help me with this? Is there a connector that connects all these things to the mother board?

before you do everything/anything see these videos first, or you can follow how to reassembly it, maybe you forget to connect cable/s

I have already watched these and everything seems to be in place. What is weird is that the vibrator which is a component of the sister board is working fine. I' m trying to figure out which cable connects the parts that are not working to the motherboard.

the 2nd video, at 5:35 , there are 3 Flat Cables, if you connect it wrong, or cut one of them, you will found the same problems
check there cables again and any other same Flat Cables
A few weeks ago my phone started to have a problem on calls. Sometimes everything works properly (usually when I just turn on the phone).
BUT, after first call, or a few seconds, the phone complete call, starts counting the call time, but I can't hear anything and other side also can't hear me.
The network and the messages are working fine.
I have already installed several ROMs, originals and custom ... the problem persists.
Has anyone experienced this? Or has any idea what problem is this?
Thanks!
you are not the first and not the last. I'm into this too. i think it's a hardware issue. I've tried everything, even this from S3, I opened the phone but I can't find the corespondent chipset. Si if someone will look into this and point to the chipset to press, I'll test it

This is hardware issue and some people from http://4pda.ru reporting successful repair.
I can only suggest, how to avoid the problem.
Aviod overheating, especially when flashing new ROM. Do it in cool place with battery cover open and do not close, until "Android is upgrading" message has gone.
can you explain/link the repair method? (point me to the 4pda topic and I'll try gtrans)
So if I flash the rom in a cold place the problem will be gone until the first overheat of the phone, which will be with the first over 5 min call, and that means it is a temporary solution until MB replaced?

Problem solved by heating (soldering) chip near previously replaced 325A
Another post explains, that chip was replaced because it was overheated and burned because missing experience.
yep. i think that right. I just found this on t-mobile support forum.
For those that haven't had any luck trying various software, firmware, setting fixes, be aware that there is a hardware problem related to this.
If you have all of the following symptoms:
-no dial (ringing) tone in the earpiece when connecting
-phone call connects but mic doesn't work
-phone call connects but no audio for both parties (where neither parties can hear)
There may be either a faulty 325A audio switch IC chip, or the solder points on the 325A chip is bad. The chip is located on the back of the motherboard, if your looking at it with the volume switch on the left with the two extension for the headphone jack on the top. You can find the chip if you follow the right headphone jack extension straight down and it's directly above the silver heatshield (basically the first IC chip you run into following the extension), it should say 325A on it. If you have a phone repair store nearby with a hot air rework station, they can reflow the solder and see if it helps or they might have to remove the chip and reball the solder on the chip. Or you can simply have them replace the chip with a new one, new chips cost like 9+ bucks, plus labor. Or if you're really brave (or stupid), you can buy a hot air soldering station with a small tip for like 60 bucks and try and reflow it yourself, but I'd advise against if you don't have experience soldering IC chips. If it's still under warranty, obviously get a new replacement handset because no amount of fiddling with software, firmware or settings will fix a hardware related problem.
Missing incall sound FIXED!!!
Following this tutorial I removed the mainboard and took it to a good friend who did a reflow to 325A chip. Reassembled the phone and after 2 calls the bug was on again. Reopened the phone and my friend did another reflow to WCD9319 chip (see picture in post 5). Since then no more missing sound. I played some games and listen some music from sdcard to overheat the under-flash zone (when there was heat, sound was not working) but the heating never happened again.

Thank you very mutch. Its really work.
Hi,
I really need your help as I have no idea what to do.
After 1 month of using MI5 Pro Ceramic black I have broke my phone,First the touch worked and there was only vertical lines on the lcd in the spot of the shatter so I could operate but due to my stupidity and of force touching the broken glass these vertical lines started to cover all the screen (Everything worked well on the phone..Sound,Camera and etc..)
So I ordered from Aliexpress LCD + Touch screen for about 70$ (Included DHL Express shipment)
When I got the screen I started to disassamble the phone.. Got everything out,Took out the broken screen and pasted the new screen on the frame (Must say all these aliexpress screens are really bad,0% protection on the screen,Not sure about the LCD quality yet but glass is horrible..Started to scratch even before I used it)
Anyways to our point..
Started to assamble back everything.. Powered on the phone and Yay! Phone is working but...
No Sound,Firstly I checked settings and everything..Ran CIT test and everything that belongs to audio giving force close..
Calibrate Speaker PA test results : State-Get impedance failed!,Speaker Vendor-None
Vibration- FAIL no short and no long
Main mic speaker Feedback,Simulation call test,Front mic speaker feedback test,Top mic speaker feedback test,
everything when I enter it giving FC with that details :
"IlegalStateException:Unable to retrieve AudioRecord pointer for SetParameters() blablala...
Headphone mic feedback test (Called on an uninitialized AudioRecord)
So in short..
No Speaker,No Mic,No headphone Mic..
Now my question is what I need to do from now.. Its not firmware/software problem for sure as before I disassambled the phone everything worked well..
My first guess was the problem is on the Sub PCB but then I asked my self..If the USB-C is working and WiFI antenna giving full signal it means the Sub PCB works so what the hell is the problem? I really hope its not something in the PCB it self as it means throw everything to garbage.. ;<
Hope to hear suggests..
I thought to order the MI5 32GB Black version take out the Main PCB put the Pro Main PCB and put also the ceramic back cover but that I would do only if I know that the problem is from the sub PCB but if Headphone mic doesnt work (Which the Main PCB take care of) then its probably in the Main PCB??
Please help!
you didnt damage the pins on the press connector? is the press connector on the ribbon cable flush / fully inserted ? Are you sure you didnt kink the ribbon cable?
I haven't pulled a mi5 apart, but can only assume its like every other phone i have.

The problem is that far as I understood of how the mi5 built and from how I saw it looks like..The Speaker located in the Sub PCB cover,Vibrate connected to subPCB,And all the SubPCB connected with the cable to the main PCB and I checked it connected good and no any damaged pins from what I was able to see..If there was damaged pins then the phone wont get charged as the USB-C wont be connected as it located in the SubPCB however it does work.. So I really have no idea what cause it..
Also the Headphone mic doesnt work in the tests..Anything related to Audio giving that FC with "AudioRecord" error..
I really must to know what causing it so I will know what to do ;<
Little update,
Just connected a bluetooth speaker,No any sound nothing..
Hi everyone! My MI5 has the same problems, no sound, mic, vibration, led buttons light, plugin earphones without notification's icon, can not play music, video offline and online video (Youtube, Facebook, live stream ..). It was happened when i replaced brooken screen. The first time when I turn on, evetything ok, I can play music through speaker, but now everything has gone..! Plz tell me how to slove this problem! Sorry for my poor E!
Hi, I ended up on buying the phone again... It's impossible to fix that problem as probably you did what I did and didn't place the motherboard correctly so a little bent probably happened and that cause to the problem.

Hi there! Care to elaborate a little more? I have also the same problem. I was replacing the rear camera module while the module I had received was broken to begin with. I hadn't really figured this out initially and I tried several times to attach it and test it, perhaps move the flex and retest, and at some I remember I found out the vibration was not there, but didn't pay attention to it as everything was open, until I found out the camera module was faulty in the end, and subsequently discovered also the whole issue with sound/vibration/key backlight etc. Instead of buying a new device, I was thinking to try and fix it, but still I'm a bit unsure about what the problem really was. From what I could figure, I didn't do anything different this particular time the audio/vibration didn't work, with respect to the previous times I attached and detached the motherboard. But is it definitely the board itself and not its flex connecting it to the sub-pcb? Could it be the sub-pcb itself or even both this and the board? In case I buy a new board (perhaps together with a sub-pcb just in case) to replace it which part should I watch out for, not to damage it again. Sorry for the many questions but you seem to be the only source of info for this specific problem.

Hi sorry for late answer,I barley visit xda these times..
After I bought the MI5 again this time in the 64gb version I tested the old 128gb motherboard (The main one) and still same problem with Vibration/Sound (While all sensors work camera too)
Which means its not the sub-pcb problem,Its the main motherboard for sure,Now what cause it?
In my opinion when I pulled of the motherboard to put it on the new screen I insert it in a bad way which made it bent a little and probably the place I bent is where the audio and all the stuff goes on..
I'm pretty sure we cant really do something about that problem as problem related to motherboard it self are usually not fixable,But if you find something I will glad to get a feedback to test on my own bad motherboard so maybe I can back to the 128gb version ;| but I doubt it..

Many thanks for the response! It sheds a little light indeed. I also ordered another phone to replace it as the cost of the motherboard seems to be equal approximately close to a new device. I'm with you, in the same view, I also once placed the motherboard quickly in the chassis without the screw that holds it together, in one of the 50 or so attempts to try and make the camera sensor I was replacing, visible to the OS, and this looseness was the unfortunate one perhaps (?). I too don't expect the sound to work again. I just wanted to double check the issue was not with the sub-pcb, which I did thanks to you. For sure I have no hopes for the mainboard to work again, but still, what keeps me from being certain it is actually the sound card that is the problem, is a very similar case I saw In a foreign forum, and also clues from my device which support the argument that the mainboard might have entered in a kind of diagnostic boot state due to a hardware fault that was apparent, where either some components are not initialized during boot, or their HW resources are taken over from the diag. ports and irqs that are enabled, in which case the issue can perhaps be fixed. For sure whenever I find a good deal on a new motherboard I will replace it, to keep it as a secondary phone, as I liked it quite a bit, but It would be interesting to see if this hypothesis holds or not. Anyway thanks again for the response!
Hi,
I've bought used mi5 with broken screen. After LCD replacement I've found that that phone has problem with sound. Exactly the same as in this thread - no sound, mic, vibration, led buttons light, plugin earphones without notification's icon, can't play music, video offline and online video (Youtube).
Someone already did LCD replacement on this phone and probably done something.
But what I discovered on this phone that problem start when battery charge aprox more then 60%.
I did flash one year old ROM via fastboot ( just to verify if it not the ROM problem) and after that everything was fine ( battery level 50%).
I did hardware test - passed 100% fine.
But when I did charge till 100% the problem come back.
That's really interesting finding... Can you tell me the same steps you did like which rom you flashed and all of that? I will check it with my dead phone maybe if I will have the same thing like you we can point on something...
mi5 lcd replaced touch not working
I bought a mi5 mobile in singapore. My display was damaged. I changed many display in india (checked in many shop). only work display (lcd). Touch not respose. please some one give solution. thank you
have same problem with op
my phone get damaged by water so im rush turn it off and open everything then go to dry it... and problem with speaker etc doesnt work just like op please help i really doesnt have money to buy new phone this month
Exactly same problem with me, just replaced the rear camera and the problem occurs
No sound, no vibration, nav led not working at all, playing video not working
Even playing sound via bluetooth speaker not working too
I believe there is something wrong with the mainboard
can anyone point out which part of the mainboard responsible for the lower board?
The lower board works well though, I tested it using other mainboard

For me the problem was that after the screen replacement (It may also apply to you after you replaced the rear camera..)
When I put back he main motherboard it wasnt sat properly,I put it beneath a small plastic holder and when I closed everything and screw and all..Problem appeared and when I rechecked motherboard I found out it got bent in the right down side and that's probably what killed all the sensors,sound and everything..
Of course that what happend to me..There is plenty of other reasons that may cause to what you experience..

I believe the chip or something similar, that control the sensor, led, vibration etc, was broken because we put it the wrong way
now we need to find which chip it is and replace it
which part of the right down? near the signal cable?

If you just checked and saw you put it wrong as I did,On the little plastic which made a little bent then I guess you lost..I would just buy new motherboard on aliexpress or just give up and buy a new phone..
As you cant really know (I mean from our side..) if its a chip related there or if its the bent it self which made problem on the connection on the board it self..
And yes I was speaking about the right side near the signal cable where you need to install the motherboard from that side where there is a little plastic like holding the motherboard..When I did the reinstall by not checking I put the motherboard on that plastic and after I closed everything and all screws got back I discovered that problem..

yeah, it means it's the same mistake as mine, that little metal thing that hold the motherboard, I forgot to eject the sim card tray and when I pull my main board it was stuck, got a little bent from there
Just wonder if anyone have the schematic for mi5 mainboard, since I'm curious and want to find a way to repair it
Not because I'm in despair of needing a phone, this MI5 is my secondary phone
Just because of the curiousity, that's all

ok bruh im already do some fking around and do ic audio replacement but no hope its still broke even my repair guy who are ex xiaomi worker are give up the problem is looks like from cpu its self but there was something interesting if u try download device info hw app in google play there was warning that the device cant read sys or something cuz it was blocked and when u look at audio chipset its was gone

I really like my P30 Pro but this last week callers have been complaining they can't hear me all of the call. It seems to be this happens for the first 10-15 seconds of the call and then sporadically throughout the call. I have searched the internet and found that the bottom microphone is not working. The reason that sometimes the caller can hear me is that there is an upper microphone which kicks in sometimes. One solution is to use the loudspeaker option - which appears to use the upper microphone all of the time. Apparently using WhatsApp for calls works too. I was wondering if there is a phone caller app which would utilise the upper microphone all of the time (unlike the default Huawei one). I suspect not, but I think it was worth asking. I have read of people having the same issue and replacing the lower microphone/SIM card unit but it still not working. One person who replaced the microphone (which still didn't work) suggested it might be "the analog to digital converter of the microphone signal" which could be at fault.
EDIT : Just to say the phone is still under warranty but I have a quite badly cracked back on the phone (front is fine) so I guess that may invalidate the warranty. The back has been cracked for quite some time though and the microphone issue is only recent
Same happened to me, changed the sim/mic board and its working again

Thanks.. I bought a SIm/Mic board and a USB ribbon/connector. I couldn't fit the sim/Mic board as I couldn't get the connector from the phone onto it so put the old one back (the board wasn't OEM and I don't think the quality was there). I replaced the USB ribbon/connector and the microphone worked. However, the USB connection wasn't great and fast charging only worked with the USB the one way around. I replaced it with a refurbed original ribbon and all is fine. I wonder if just refixing the SIM board and USB cable would have sorted the microphone too a) why would me replacing one part and you replacing a different part sort the same issue? b) I have seen a post from someone who sorted it by applying pressure around the edges of the phone and the SIM area.
I've also started getting this problem. The other party can't hear me on phone calls for the first ten seconds, and when they finally hear me it's very poor quality. Google hotword recognition also isn't working. I'd only seen people saying they'd replaced the sim/mic board and it hadn't helped, but perhaps they didn't change the connector? Good shout, I'm going to try a refurbed cable.
Having issues with the lower microphone that's been listed all over the net, ie delay in hearing me when answering calls and google assistant not hearing me.
Two lower sim/memory/microphone boards later still didn't fix it. For me swapping out the USB ribbon connector has cured it. Just in case this helps someone.

Hi, I replaced the small board as shown twice, but it was the usb lead also shown that ended up fixing it. I'd start with that. Good luck
Hi! I've got the same issue for some time ago... just purchased a new microphone PCB and replaced with no success. Diagnostics on the phone launched a NON WORKING message
Then just surfing the internet I found this forum where I'll share results once I replace the USB charging (and more) flex.
Cross fingers!!
UPDATE!!
** PROBLEM SOVED**
After replacing the charging flex, the microphone is working FINE .
Selfdoagnostics PASSED succesfully for the microphone testing.
▶ I can not realise about what's the hardward problem but it's true it works.
These are cheap pieces, and taking into account I'm in love with this LAST-Google Serviced Huawei P30 Pro... I really believe it will last at least 2 or 3 years more in my hands!!

Glad you found a solution. I warrantied my phone 9months ago because of the microphone issue. Now it is malfunctioning again unfortunately. The p30 pro has everything i need, still full day of battery. Out of warranty now and prepared to try to repair it by myself. Trying to find how thick tesa tape i need to put it back together, which tape did you use? Do i need Best B7000 glue aswell? Havent taken a phone apart the last couple of years so I need som basic guidance regarding glue and tape.
Best regards
