After my attempt to fix WIFI my back speakers became very silent. Today I replaced battery, speakers aren't working anymore at all :crying:
Can someone tell me what should I do? I noticed that one of those thin copper "legs" which are supposed to touch copper plating on casing near speakers was bent, so fixed it, but it didn't help
replace the speaker it cost less than £3, I damaged mine when replacing my battery and rear housing and had to replace it, it's really easy.
Just search "HTC one x speaker" on eBay and you'll have no problem finding one.
guys i replaced screen and battery now loud speaker is dead .. i ordered new one and still not working ..

After i had taken mine apart, my speaker wasnt working either. I tried connecting the speaker pins to the board manually using wires.. The speaker was then working.
I then realized that this must have been because the pins of the speaker was not connecting to the board.. What i did was removing the black tape which is just around the speaker it self and then making the pins "higher" if you get what i mean.. After this i got it working again.
Let me hear if you get some news

how did you lift pins they are on flex cable .. i manually put speaker pins onto flex cable pins but didnt work ..and when i put one pin from speaker on flex pin and other completelly somewhwere else not to pin it kind of worked .. so weird
Have a look at my attached image.. It shows two speaker brackets..
As you can see on the bracket lowest in the picture, i have removed the black tape.. Also those two pins i have marked are the ones i suggest you to lift.
The flex cable you are talking about is that the one which is attached to the lcd bracket?
EDIT: Forgot to include the image!

Hmm if the speaker is not giving any sounds with that i can only think of the flex ribbon not being connected to the mainboard up on the top right of the battery.

of course it is even that flex cable is new.. leds lits up
and speaker starts working when speaker is in this position (the pins are against battery and one leg of speaker touches that top contact and right leg touches that light grey area of the flex cable then speaker working i can hear sound but not loud as it should be maybe half loud even when on max vol.

I have a few pictures of my galaxy nexus broken down if anyone would like to ask me questions on how and where things go they can. I actually find this phone to be very easy to get apart and if careful can be reassembled in 15 minutes. I was actually replacing my speaker with some old parts I bought off a guy. No more crackling! Anyways in the process grabbed some pics
U can see the first three are the screen bottom speaker, main board, vibe, etc. The last pic she's all back together

Yep this phone is one of the easiest ive worked with. had to open mine to replace the earpiece. the only thing to take care of is the volume ribbon and vibrator wires, they can snap off really easily.

Yes sir....I just stuck a razor blade between them and the housing and they come right off connected to a gel like glue. This was good because sticking them back in place they actually stayed. U also have to remove the vibrator motor and the long black wire running down alongside the battery compartment (it has connectors on each end) then of course your two ribbon connectors for main board then one ribbon connector for bottom speaker. Didn't touch cams no need to.....very very easy job in fact it was to easy.

Yes for sure...but if u do not feel safe doing it then take it in. I know to get to the usb the whole speaker and housing comes off of the top of that. Which is one screw then a ribbon fairly easy....then u just work something thin in between that and housing like a guitar pic or Mac card. I would go with guitar pic tho so u don't mess the corners of your card up. I know that once the speaker portion is off u see in my first pic the USB I think has its on board. I truthfully did not take that portion of it out thought it was kind of pointless. If u need help I will assist u if u decide to do it yourself

I replaced my back cover and apparently I damaged the GPS chip cause I have NO gps lock, software side its ruled out (I flashed many diff ROMS, kernels and Radios and it used to work well before I opened up my Gnex)

The battery cover? Hmmmm. I am pretty sure the GPS chip is on the opposite side of motherboard. Looking at ifixit photos it says right by rear camera on the opposite side of motherboard.
Edit...also if u look at first pic in my pictures look on right side of battery compartment . See the black wire with the connectors on each end? I wonder if the connector closest to bottom came loose or has something to do with it

Thanks, appreciate your time.
I checked out ifixit, thinking that in the process of removing the cover I could of hit the GPS chip or something, but since you pointed out that its on the opposite side of the motherboard that's not a possibility. Since I have not removed the mother board.
I have not opened it again, afraid of ruining something else.
But I guess I will have to in order to check the wire you speak about.
Salutations
I sent my phone in for repair to Samsung via Expansys for a bad external speaker. Back when it went bad, phone was too new to have all parts available as spares on the net plus the phone was still under warranty so I send it back to Samsung via Expansys-usa. But what I think happened is that Expansys didn't send it to Samsung and repaired it inhouse. I can say that because all screws inside the phone had chewed up heads and the repair didn't look good however the external speaker was working. First thing I found out that external volume rocker was not working anymore. So I send it back again to Expansys and I just received it back today with a note saying that the volume rocker ribbon pins have come away from the main board and taken the pin with them.
Bottom line is that they didn't repair the phone. Any ideas on how I can get this fixed? Do I have to change the ribbon? if I want to do it myself or this sort of damage requires a new board?
Any ideas comments are appreciated.

Hi Sarni,
I accidentally snapped the ribbon (refer to attached pic, circled in red), and now my speaker is not working anymore. I guess that ribbon was for connecting the speaker and headphone jack? . What do you think i should do now, replace the whole piece?
I also intend to replace my damaged charge port, but not sure how to proceed for that.
Thanks,

Hello people.
I have a problem with my headphones when plugged in my HTC Desire, when i plug them in the phone shows me they are plugged in but only one headphone works (the left one), i have to mention the headphones are 4 pin ones (mic + 1 button) and mic and button works good but the right headphone doesn't . They are not faulty as i use them in my laptop and they work good. Sometimes they work, sometimes they don't.

Take a needle, and try scraping the bottom of the phone headphone plug. Dirt usually gets stacked there, and it needs cleaning from time too time.
Not working, same problem. If it take them out a little so that the phone doesn't recognize the microphone ring (connector on jack) they work good, when i plug them back in just left one works (the one with the microphone).

Maybe your headphones are not compatible with your phone. I remember people saying something about connections not being standard on the phone so some headphones won't work properly. Try some other headphones and see if the same thing happens

Then it's 100% socket problem. If abaaa's advice didn't help you probbably the welding on the socket got loose. For that you need to disassemble your phone and see which contact is bad with a magnifying glass

The socket feels solid in it's place and i don't have a magnifying glass around.

It should feel solid. Problem is that welds come a little loose. Try to move your headphones jack in the socket in all directions. If they play fine at some moment it's the weld

The rear speaker on the HOX sits in the bottom of the rear shell and has two gold coloured spring pins that push up against the mainboard. I have come across the problem when fixing them that the pins get pushed down so they don't contact the board, or can be easily broken off if bent to far. Try bending pins up so the tips sit about 1-1.5mm above the speaker housing. hopefully the picture I've attached shows the pins clearly enough. If this fails to work try replacing the speaker, they are fairly cheap if this doesnt fix the problem you may have a hardware/software fault but try the easy stuff first.

Was thinking about it again and pins do not sit on mainboard but rest on the flex cable that also houses the bottom led's for the home button etc.follow that back and make sure it is connected properly in its connector although it should be if your home button led's are working. Also check there are no small tears accross the flex cable,I have also come across tiny tears across one track before.

Hey all,
I just replaced the charging port on my m8 and wanted to let people know it is straight forward. My port got corroded and was shorting out, melting the adapter and not charging the phone. I sent it in hoping for warranty, but the replacement quote was $400! (due to S-off they "had" to replace the entire motherboard). The phone has a separate pcb with the micro usb charge port and headphone input.
example:
http://www.witrigs.com/media/catalo...a71cb48e3d52cb890e76f9e6353/1/0/109063-01.jpg
To remove this board you need to do a few easy things:
1) disconnect the ribbon and remove the insulating tape (to reattach to new part)
2) unsnap the small white power cable
3) loosen the screw on the motherboard near the headphone input. This is clamping down the assembly a bit
tools required:
phillips 00
t5 torx bit
spudger/guitar picks
I would recommend prying the phone out of the frame starting from the bottom. I started from the top and bent the thin strip of aluminum above the sim slot when prying it out.
Also, you can pry the bracket/spring off the top of the old usb port to give the new one a tight fit if your replacement didnt come with it (like mine)
Lastly, just note that power button fell out as soon as I pried the frame apart from the guts. This made it a bit of a pain to reassemble - just be sure to reassemble with the top in first. That will keep the power button in place.
The replacement part cost me $30, so it was definitely worth it! phone now works great.

Hey there. Interesting to know that you replaced it all your self . Did you put everything back perfectly ? I mean the display being aligned properly to the body, the speaker grills being flushed with the body; ? Weird to ask, but did you damage anything while doing it all yourself ? Like the screen scratches, or something else ? Sorry, for asking these... Thanks in advance :good:

I haven't re-glued the speaker covers back on yet so I dont know if they will be perfectly flush or not, although they still look flat so I think it will look good.
The only damage is a slight bend in the frame on the screen side of the sim tray slot. The metal is thin, and I pried against it to get the hardware out of the frame. That is why I recommended to start from the bottom when separating the two. Doing this should allow others to avoid this problem. It is slight, maybe 1/4mm gap where it used to be flush along the side of the screen above the sim tray.
Otherwise everything was smooth. The screen/frame etc are still mint.

Cool, you've done it like a pro then. :good: .Any picture describing the damage would be helpful, if you can provide. Is the display mint ? No scuffs/scratches on it ? But, my speaker grills were damaged onto the edges after the repair was carried out. Does yours show the same sign ? I don't mean the flatness of the grills, but the damage that should be done, while prying out the grills. A picture showing your damage would be helpful to me. I could do the same, if you insist. Thanks ! :good:
Mine is busted. But I cannot find the PCB. The link in the op is dead.

I actually got one off eBay for $17.21. Works perfectly.
Just wondering....
Sounds like you were able to avoid some steps in the teardown guide, if I recall it was damn near a total disassemble. Do you have a lot of experience with phones? I want to fix mine, but don't need a tedious project right now. If I repair mine I'd like to put a mini USB in place of the micro if possible, I've seen too many damaged micro usb to trust or like them. As for the speaker grills, if you're picky buy replacements, they're cheap.

My HTC M8's main call microphone has stopped working, and through searches on Google it seems that perhaps that this mic (first mic, non-speakerphone mic) is built into the charging port. Is this the case? I cannot find anything that explicitly says this, and I'd love to get the phone back in working condition.

I called HTC, the mic is on the USB port, although you should make sure that it's not a software issue first. There are several threads on the internet easily found through Google which discuss doing a factory reset to resolve this if it turns out to be a software problem.
Thanks for your reply. I did a factory reset when I got the phone but it still doesn't work. Does that mean it's not a software problem and that if I replace the usb it should work?

No, but from what I've studied about it, it should work. Feel free to contact HTC, they actually have a live chat available somewhere on their website. Good luck to you.
Very interesting, I contacted htc and we went through diagnostics together and the rep said that I have to send it in. I asked him if the mic was on the usb assembly and he said that it wasn't and rather it was on the motherboard, and I clarified that we were talking about the primary mic which is located near the usb port. Confusing bec everywhere I saw online said that the mic is on the usb assembly. Go figure!

What did you end up doing? Did you discover if it was on the motherboard or the part with the USB port? I've waited a while to repair mine for other reasons, and I am now prepared to fix it. Any information would be helpful.
Just a few notes on my own experience.
I replaced the screen in my friend's M8 a few months ago. Seemed like everything went ok, except after I got done, the mic didn't work anymore. This is strange because it worked fine before, and all I did was remove/replace the circuit board in the process (yes, the small one at the bottom with the uUSB port). However, the upper rear microphone was still working I believe, because people on the other end of the line could still hear if the phone was put into speakerphone mode. I don't know why it would stop working all of a sudden.... Ran the HTC audio test using *#*#3424*#* to confirm main mic wasn't working and that the aux rear mic was.
Fast forward to this week, with my own M8. The uUSB connector was going bad, and I was having trouble charging, so I figured it was time to replace that circuit board. Ordered a new one and replaced, but when I got it back together, the USB port was fine of course, but my mic wasn't working now, just like my friends! On top of that, the headphone jack didn't work at all. Most likely the "cable inserted" signal wasn't getting back up to the motherboard, but didn't check. So pissed off. Also, the new board I got didn't have the bottom left RF connector/circuitry populated. Thinking from research that it might be for the GPS? I should have tested when the board was in there, but didn't. Fixed a bad solder joint on the original board's uUSB connector, which helped, but still charging is a bit messed up. I'd rather have a working mic and headphone jack and have to play with the cable to get to charge for a while until I get another board (from another supplier, jerks).
Yes, the mic is the small chip on the very left side of the board. It has a hole underneath the chip, going through the board and to the front face to receive the acoustics.
I don't know why the mic not working is so common after an HTC One M8 tear down, as it seems many others are having the same issue. One theory I have is that pulling the circuit board from the motherboard while power is still applied (not unplugging the battery first) might be jacking the microphone somehow. Just a theory, but I'd recommend to be safe that anyone replacing the board should unplug the battery cable before replacing the USB/mic circuit board.
I'd just like to chime in to say that I've read about some people having problems with the mic not working after replacing the USB board. From what I understand, there are two different versions of it, and replacing it with the wrong one can cause that very issue. You should look into it.

Mic broken after USB repair
Old thread but I have the same problem. Replaced USB board and now my mic does not work. However I am pretty certain I did order the correct board (had 2x connectors for my Verizon HTC m8). And my microphone jack work great which others indicate is often broken along with the mic. Anyone have any workarounds?
Hello, I have replaced the screen and housing on my LG Nexus 5x which went OK.
However, I now have no audio from the loud speaker under certain situations. I have replaced the earpiece (I now don't think this was anything to do with it) and headphone jack to no avail but have narrowed it down to the lower back plate (the bit you screw in over the headphone jack). Sounds through the headphones work correctly BTW.
When the back is pressed on very lightly the speaker works. (so the pogo pins connect to the cover/speaker). However, when you click the plastic on speaker cuts out. My guess is something gets pushed in too far so something either loses contact or makes contact that shouldn't.
Any thoughts/ideas most welcome. I've made a little video to illustrate what I mean: drive.google dot com /file/d/1CU37Fvrq2NfL6WKNS0sn0ssw_3s-BWx1/view
