Hey There,
I am attempting to try and fix my phone because it has multiple problems associated with it such as a nonfunctional power button, a faulty in-call speaker, and blind spots within the digitizer that are unresponsive.
My guess is that the prior owner dropped the phone and some damage was sustained to the flex cable/pcb which runs to all of these things causing the phone to have some broken connections here and there.
I plan to use a teardown/repair guide to use this, BUT!
Does anyone know what else might be the problem, and where can I find a replace flex cable/pcb and how much do they usually go for?
I live in Canada...
Appreciate it.
You can get them off ebay for ~50 USD. ebay item number 260744426322. It's from China and will take forever but that's about it. Sounds like a flex cable though, hopefully it doesn't need a new digitizer too.
so the off white tab that holds the pins in place broke off....and also some of the pins broke off. So im wondering if this is completely impossible to fix? is there anyway to rig the lcd screen to turn on still or am i screwed? btw it is the smaller flex cable version. i dont have a sprint upgrade for a good year and a half so im not trying to wait that long and my htc hero is getting quite annoying to use compared to my modded evo which was gloriously fast.
Hey did you ever get this fixed?? The same thing just happened to me...
A new digitizer for the Evo only costs $20-$30. Just buy one and replace it. Problem solved.
Hey,
It is possible to fix you just need a new lcd screen or digitizer here are some ebay links for them I am not sure what one you need..

But just replace it dont try to rig it or anything it will cause more damage then good.
I hope I helped If I did please hit the thanks button,

I think he means the connector on his logic board broke which is hard to repair afaik

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.
Any ideas?

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.
microphone on charging port?

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 too am also curious if the mic is on the usb part because my mic doesnt wrk when i make calls.
Will replacing the usb port fix the problem?

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?

I would think so, yes.
Thanks! Do you know of any online source confirming that?

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?
