HTC One motherboard connector - One (M7) Q&A, Help & Troubleshooting

so yeah, a couple of months ago I disseasembled my htc one to replace housing and swap cameras, because of the purple tint. Now, when I got all my parts together, when I open up the camera, rear camera doesn't work. I got two new daughter boards, two camera sensors one old one new and none of them does work. However the front facing camera does work. I didn't have a clue about what happend until i noticed a probably shorted out pin on the main motherboard connector. I quickly assumed that it could be the reason, but seriously, why does the front facing camera work. Could the burnt pin cause this kind of problem? the pin is on the bottom side and about in the middle if you look into the picture. If it's the case, could I replace the connector by soldering a new one. If you could drop me a link to the replacement connector that would fit.

I had same problem your camera isn't detected prob go into root explorer and see if camera module shows up their on a system level . If it does you have a software problem if it doesn't show up the cpu isn't detecting it and you have a hardware problem bad wire bad camera bad connection etc

Attaching an image. I can see camera there so i guess this is software? What should i do?

What a joke man..

After the repairing of my X1's ribbon cable I went home gladly with my X1 functional... partly..
I noticed there's an error in signal in my X1 when I was checking my phone at the SE center.. But I thought it was maybe due to poor reception thus I neglected it..
Now I know that there's some new problem arise.. Any idea how a ribbon cable can affect this?
The signal error is not due to flex, but most likely an assembly error/other fault. Could you explain better what type of error are you getting, e.g. SIM is not read, connection cannot be made, calls cannot be made, data is not received?
Flex contains connectors for front camera, ear speaker, LCD, light sensor, front keypad PCB and optical keypad module, as well as LED lights on all sides positioned on the flex itself - therefore problems with any of the above can be attributed to the flex. However, flex consists of different separate areas, where problem with one will not necessarily mean the whole lot of things will be affected. For example, not working ear speaker may be present with working rest, VC camera not working, while LCD is fine etc. When the lot fails as a group, then the problem is either flex at the slide point, flex at the PCB connection point or the main PCB itself, in which case it may not necessarily be the flex. So what is the new problem?

It read my SIM card but I'm not getting any connection signals from my service provider.. Yeah most likely would be an assembly error
I really got annoyed that I need to go back to the service centre and fix it again. Today I went there and they said technician aren't there and I need to return tomorrow.
Thanks for the reply. Now I learned something from you. Thank you

The antenna module is very easy to access, see disassembly procedure and see if you can reposition it. http://www.formymobile.co.uk/xperiadisassembly.php Speaker and antenna module is positioned on the side OPPOSITE to the camera, you can see removal on photo 4.

I took my phone to the centre for another checkup. And sadly they can't even identify what's going on with my signal too. They're sending it to the HQ. Guessed it'll take another long time to be fixed. Hope I'll get Leo for free tonight. Then I'll just leave my X1 goodbye~

[Q] Replaced microphone not working

I've recently replaced the bezel on my phone and in the process broke the ribbon between the two hardware buttons. I ordered a new one and swapped them over with what I thought was no problem. The keypad note works but now the microphone has stopped working entirely. Could this be a software issue (I do doubt this) as I'm on a stable version of CM10? All the connections are linked up and everything looks fine. This one has me completely baffled
open it up again and check the antenna cable again. Maybe it isn't inserted correctly?
That's a good point. I accidentally crushed the antenna cable but wasn't aware that it was relevant when considering the microphone. The rest of the phone works fine including the mobile signal. May have to link up my old mic just to check this
Aargh! It turns out that the old mic is still working so the new one appears to be the issue. Hmmm, wonder what gets a better resale value a phone with no working buttons or one with no working mic *sigh*
well I changed once front bezel from SGS1, too. Still have the old one. Maybe just buy a new parts? I think those don't cost a lot. Whole front bezel cost about ~100e.
I think after this poor attempt to repair the phone I'm gonna put the device up for sale

Rear camera turn black when use it

Whenever I try to use the rear camera the display turns black while only showing the HUD. The HUD works fine, but the camera doesn't work at all. Nothing is blocking it either.
When switching camera modes (to manual mode for example), an error pops up saying that the "camera is not available"
IMPORTANT NOTE: The front facing camera is working perfectly fine.
Things I tried to do (aside from shipping it for repair):
1. Android repair via the PC companion software
2. Internal reset
3. Safe mode
4. Clearing cache files for the built-in camera app
5. Installing an alternative camera app (the built-in one was disabled)
6. downgrade and upgrade
7.change camera for new one (tested)
I had same situation with regular Z3. Someone brings it to service where I'm working and my first think was camera fault but changing camera didn't fix it. Near camera connection You can see some small capacitors, we call it filters. It looks like capacitors but it's soldered not only on opposite sides but 2 points on both sides. In regular Z3 there was 5 elements like this to change and after that camera starts working. I don't remember how exactly it's made in Z3c but it's really possible that it's the same issue and same way to fix it.
One more thing, if You can check one one more camera to exclude camera itself cause most issues like this are caused by faulty camera. I had many phones (most Z1 and Z1c) with this issue and changing camera always was the solution.
Good luck.
Same Here. Need help too.
Sent from my D5803 using XDA Free mobile app
I have three cameras and two z3c, I interchange camera and phone and always the same result
At this moment I don't have any Z3c to disassembly (except mu own but under warranty) to check where those capacitors are but if You could take a picture of camera connector on motherboard and near area I can mark which one should change.
@Chamelleon
Main camera not working
I have the same issue with my Z3 compact. The issue started happening on the 11th month of my one year warranty, I sent it for repair (14 business days y + shipping time back and forth). It came back with the same issue. Sent it back right away. After another three weeks without my phone, I got it back. Guess what? EXACT SAME ISSUE!
I called their support line explaining what happened, the guy told me that there is nothing they can do about it since my warranty expired. Of course they didn't have in consideration that I sent my phone before it expired and it took about seven weeks back and forth. There wasn't any sort of damage on my phone, was never dropped or damaged in any way, I never submerged it even if in theory, that would be ok. The report said "it has reviewed the functioning of the unit, unfortunately the defect is in the PCB so it is not able to undergo repairs to it."
The guy on the phone told me what he thought the report meant. It means there is damage on the main board(not caused by me) and the one year warranty manufacturer warranty department won't repair it. Maybe, if I had bought the 2 year "extended" warranty, they could do something about it. I asked if the issue is that my one year warranty was expired or if it is something that they just don't fix unless you get the "extended" warranty. He couldn't answer me and the only thing he said was "is there anything else I can help you with?"
From what I understood, there are two completely different departments, the one year manufacturer warranty that only cover some things. Not even sure what, because if it's broken screen, water damage or any physical abuse, they won't fix it. If it's a problem with the main board or PCB, they won't fix it either. It is a mystery to me what gets fixed in that department. The other department is the 2 year extended warranty. I'm not sure what they are willing to fix there, but from what they guy on the phone told me, it's more than the one year regular warranty.
Long story short, after two trips to FedEx, at least 8 hours total on phone calls, more than 7 weeks without my phone, I ended where I started. Sorry Sony, never again. Worst customer support I have ever experienced.
At this photo I can see only 4 of this capacitors and marked it, maybe it should be four or one I missed cause quality. Anyway regular Z3 has 5 like this and after changing all 5 camera start working again. You can desolder it from most Sony phones, I used capacitors from MK16 (Xperia Pro). So find some Sony board with capacitors like this and ask someone with good hot air solder station (if You don't have one) to change it.
Any news to this problem? I bought used Z3C with black rear camera problem because it was cheap. (Yes, the front facing camera is working perfectly fine). So far I have only tried software fixes and obviously they didn't help. I ordered new camera module from ebay and I'm now waiting for it. Has anyone tried soldering new capacitors if the new camera module doesn't help?
EDIT: Here is another thead with same problem: http://forum.xda-developers.com/z3-compact/help/rear-camera-hardware-detected-black-t3231509
As I said I've done it only in regular Z3 but If You gonna try give me some info is this solution is also working in Z3c case.

I'm still waiting for new camera module. If the new module is not working I will try soldering new capacitors. I will keep you up to date here .
Any news??
Completely forgot to post this, hope it help someone. I made the same thing with black camera on my Z3c. After I broke audio port in my Z3c and had to send it to warranty I took my gf phone, Z3c also. I restored my TWRP backup to her phone and all except camera was working. Camera was completely black but only main, front was OK. After that I was afraid that it's another hardware problem like Yours but after reflashing to stock problem gone. I repeated it few times to check if I'm right and I was. After flashing backup from another phone even without TA and Kernel backup there is a problem with camera.
So I was wrong saying it's only hardware problem. If anyone still has this issue and didn't reflashed his phone check it first.
@Chamelleon yes it's somehow a software problem (if we could say that ). For me i did fix it.
I did a Nandroid backup for my black Z3 compact (camera works properly) an restored it on my new White Z3 compact (also camera woks fine). after restoring the white z3c rear camera shows black screen, the front one is good.
=> i did a format factory reset : didn't work.
=> flashed a TFT file : didn't work.
=> flashed a D5803_23.4.A.1.232_Customized FR.ftf : IT WORKS !
and then i remembered that my phone was from "SFR" , a french network provider.
i hope this helps also
Edit: too new account, would be nice if a mod unlocks the posting of the direct image links and fixes the links - I think they are useful as this is a common problem and i already invested hours translating russian and documenting my research nobody else should have to do it
for me it was a hardware problem after dropping it.. I even changed the camera module.
Did some reseach, russian sites have some input:
Layout1: directupload.net/file/d/4472/9andayji_jpg.htm
Layout2: directupload.net/file/d/4472/vzvgbqqo_jpg.htm
It was loose, but when i tried to push it down with a hot metal to "solder" it, at some point it jumped away and was lost because it is so tiny!
Missing part: directupload.net/file/d/4472/qmut35qt_jpg.htm
The russian site suggest this soldering of bridges, however its not clear to me if they mean one of this electronic pieces (4pins each) or also the lower one.
Russian: directupload.net/file/d/4472/ag43kmda_jpg.htm
The question is now how these (likely) filters (because so close to the camera have to be bridges, it seemed to have worked for some russians:
Pins: directupload.net/file/d/4472/k86j53hr_png.htm
Not sure if there are 4 indipendend pins or if for those small footprints of electronic devices they use only the edges and then they have the same signal.
I was not able to see any text written on those two things, however i didnt have any magnifying glass.

So I changed my camera because I thought it was a hardware failure (tried every other method before: going back to stock, wiping camera files etc.) and it STILL is black. Did you have any success with your camera?

Try flashing stock ROM based on your country as i mentioned up.

Me not (also changed the HW cam), the guys on the russian site yes (even with other similar sony).
Just check if there is something loose, maybe you are lucky and its a software problem *fingers crossed*. To me it happend exactly after dropping (and changing the screen which went without problems) so I was quite sure its HW based.

Hi basmok,
First off thanks for the research and for the pictures!
I have a similar story, phone was dropped, rear camera won't work, tried different ROMs without any luck then took phone apart and saw that one of the four tiny capacitors
just fell off and now it's MIA...
The last pic from your post (directupload.net/file/d/4472/k86j53hr_png.htm) which I assume shows the soldering of the bridge doesn't seem to work...
Do you still have that pic?
Also did you make any progress on the camera fix or gave up?
Thanks,
Ati

You were lucky, they were already in the recycle bin and deleted on the camera. Best I could do picturewise, i dont have a macro lens. Here we go, added all to imgurl so hopefully they survive longer: http://imgur.com/a/Of1DY
And no, didnt make any progress as i dont know what component they are. Normally all components have lasered some code but not sure if its just too tiny for my eyes or if they dont have it. I was a bit unlucky as i didnt have a soldering tool, so i tried it by pushing the pin down with a paperclip which i headed with a lighter --- well it jumped away and was not the best approach

No Audio after screen replacement

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

found the schematic here

now on the journey to repair this stupid mistake, lol
any help from someone who are an expert in this thing will be really appreaciated

Yeah, tried it before, and the audio chip is gone
Perhaps something wrong with the audio chip, will try to replace the IC tomorrow

Phone burst into flames during repair, need advice with new parts.

So, the screen on my Note 4X broke, and I wanted to replace it. Long story short, the battery is glued down hard as **** and I managed to damage it, and it burst into flames. I'm fine, I was prepared, nothing but the phone suffered any damage.
But now I'm sitting here, with a phone that's basically still fine minus the frame and the battery, and I still want to repair it.
I'm faced with two questions, first of all, I managed to find (I think) every part I need, but one eludes me. I don't even know what it's for. You can see it here (minute 9:11-9:27):

It says "C6_LEDFPC_V1.0" on mine. Google tells me nothing about that, and it's not a part I have seen on the repair shop sites. It doesn't even seem to be present on complete frame+display assemblies like this one:
https://www.aliexpress.com/item/LCD...edmi-Note-4X-hongmi-Red-Rise/32810566637.html
And apart from that, I wonder if I missed any part.
I still have:
A new display+digitizer, the back cover, the mainboard with the SoC and the two cameras, the PCB with the charging board, the battery cable, the sim tray, the fingerprint reader, the loudspeaker.
I need:
A new frame, an earpiece, the mainboard flex cable, the side key flex cable, a battery, and the one mysterious piece.
Is that everything? Does everyone has a basic list of all the parts?

I've been thinking that in the video, the guy switched on the phone without that part. so that part shouldn't be a very major component. In my opinion, it can be some sort of sensor. I personally feel its a magnet screen sensor for covers with smart wake up function.
The reason I say this is because when i touch a small magnet on the entire front panel, It gets stuck on that same point.
However I am not very sure as the smart wake is not triggered. Maybe it is because I am on LineageOS.
Hope It turns out helpful.
You will probably need the vibrator motor too, its quite small and easy to lose as I've found.

That part is the LED for the capacitive buttons. Not important at all if you cant find it
