Hi ,
My speaker at ear was not working due to oil went inside ear speaker. I removed the speaker and cleaned and put it back. Now the issue with speaker is fixed. But Camera and flash light stopped working. Error is "Failed to open " camera. Also YouTube app stopped working.
I tried keeping back side open of and It is working when screws are not inserted. While inserting screws it stops working. What may be the reason for that

Right, I spent the last few days wracking my brain over this problem and similar, so hopefully my solution actually sheds light, and I think in your case it might!
I needed to replace my screen so had to do a full opening. I thought maybe I damaged the motherboard or something as I stupidly had to remove the screen first (not good) so thought the heat I applied did something to the camera module. Nope. Basically, when I put the phone back together the following wasn't working: Camera, Flashlight, YouTube. The camera would fail in safe mode, it would fail in the *#808# hardware check, I did a factory reset multiple times, flashed different stock ROMS (my phone is vanilla and not rooted, so I only used official ROMs)... not a single thing helped. I realised very few posts complaining about the issue actually transparently say they opened their device, for embarrassment or ego, or I dunno, but it was super vague as if the camera/YouTube failed all on its own, which is odd to say the least.
Anyway, in my case, do not tighten the screws tightly when you reassemble the phone. This is part of the problem. Screw enough that it catches and then leave it. Don't screw it any more. Next is where yours might relate to mine in terms of camera. There is a tiny wire that trails from the motherboard (near the vibration motor) down to the loudspeaker. In my case, that wire was getting pinched when I put the loudspeaker module back in place. This is what caused my issues for the most part. So check the wire is seated in the frame outlines where they should be.
TLDR: Check the very thin wire from mobo to speaker - that might getting pinched during reassembly.
I really hope this helps you because it was getting on my nerves that noone suggested it. And if it does not help... I'm sorry... I hope you find a solution soon!

Hi,
whenever my hd2 uses the vibrate feature, it only gives off a weak vibration, together with a more high pitched sound than usual. Is this a known problem?
thanks
its happening to me :S
look carefully at the camera flash cover...most likely, this cover has been depressed into the body of the phone.
i had this same problem about a month ago. so i carefully saw the (widely available) dis-assembly video. you only need to go through about 10% of the dis-assembly steps...essentially, just remove the back cover and re-seat the camera flash cover.
once you remove the back cover, you will notice that the vibrator motor lies just beneath the camera flash cover...that is why you hear that funny "new" vibration noise.
one final note...if you decide to fix the problem yourself, be sure to use a PLASTIC prying tool. i didn't and i got some scratches and nicks on the bezel area
As the title said, is there?
Cause my DHD performs okay in call, it just that when im just using it normally it sometimes do this weird random clicking on the screen everywhere and lead to my phone unusable until i push power button and unlock again. I just discover that the culprit is the proximity sensor, so i covered it with black electrical tape and for full day i didnt encounter that weird bug again. Ive try to flash to custom roms and to such no luck its still there...
Your phone is faulty. Why don't you just get it replaced .
Just remove the tape and i tried blowing at the proximity sensor, and i think it works. My guess is that the hole in the ear piece is big enough that some dust got in and block the sensor. Im still trying it now and so far so good.
Hey i installed gingerbread android 2.3.7 on my phone again but this time im getting really weak wifi signals... i'm only 5 feet away from router. It was not like this before so i do not know whats going on ( i only dropped my phone twice)
can you guys help me? is it a software issues or hardware?
happy thanksgiving
I would recommend installing a few different roms (that are known to work with wifi) and see if anything changes/improves.
If nothing improves, maybe flash back to winmo 6.5 and see if wifi improves.
If nothing improves then, you may have damaged your wifi antennae when you dropped it then hit up T-mobile!
Best of luck mate.
Possibly knocked the wifi coax loose from the mainboard. It's pretty easy to open up an HD2 and reattach that cable, I've had mine come loose before and that's what I had to do.
I'd definitely try the steps in the above post first just to make sure it's not a rom or kernel specific issue. And if it's still under warranty, don't bother taking it apart and ruining your warranty, obviously just return it to t-Mobile.
hey can you explain in more detail how to push back the wifi coax cable your talking about
Remove the battery cover, battery, sim card, and sd card.
Remove the 4 torx screws that are under little round stickers under the battery cover.
Using an old credit card or a plastic knife, slide between the screen and the housing to release the little plastic clips one by one which hold the housing to the phone's chassis.
Take your time and be careful not to scratch the housing or stick the card/knife in too far, damaging the fragile stuff inside,
It helps to put a little pressure on the back side of the screen wth your thumb while orying with the credit card (back of screen under battery)
The wifi coaxial cable runs from one corner of the mainboard, up along one side of the chassis, is taped together with some other wires, and leads to another small board up near the top of the phone.
Check the connections at both ends, making sure they are connected firmly and are in straight.
You might want to unplug them, just to be sure and hear/feel them click into place.
Take your time, set yourself aside a nice little workspace, and if you are unsure of anything, don't hesitate to come back here and ask.
There is a disassembly video here in the HD2 section somewhere, I think it's in HD2 General. It'd be worth it to search for it and watch at least the first part of the video, just to get an idea what you're dealing with. It's not a very hard job, it should take you like maybe an hour/hour and a half start to finish.
This will void your warranty permanently though.
Thank you sir i just followed the steps you did and it fixed the problem my wifi works fine but now i have another issue....
i dont know if i touched something or disconnected something in the process but my sound, vibration and volume button does not work. External speaker is not playing any sound (no music or key button taps) and no sound is made when placing a phone call BUT the other person on the end can hear me just fine so i'm guessing i might of disconnected like the speaker. ( my assumption)
thanks again for your help
Oh and when a call is being placed or recieved the screen automatically turns off and it becomes non responsive i.e if i take my phone off the ear and want to put it on hold the screen is still black instead of turning back on
The screen going black during a call is a pretty common problem with the HD2, and is likely not related to disassembling your phone as long as the screen functions normally otherwise. Since you didn't take your phone far enough apart to affect the light/proximity sensor, I can't imagine how disassembly would have affected it. You would have to take the mainboard and screen out from the chassis to get to that sensor.
The volume problem on the other hand, is probably due to either your volume rocker not being placed correctly during re-assembly, or the speaker contacts not being aligned properly. You'll have to take it back apart and ivestigate what went wrong.
Try going into Settings/Sound, and checking that the volume is not turned all the way down. If the volume is not all the way down, then you should be able to hear sound, so your speaker is probably not aligned properly.
Does your volume rocker feel different than before? If it doesn't make a definite 'click' when you press it, then it is probably slightly out of place. Also look for any wires that could have been pinched and damaged when you snapped your phone back together.
What is a volume rocker? When i start the phone it usually vibrates once then goes through the starting procoess. Now it doesn't vibrate at all. Phone turns on and i click the volume button up and nothing happens. I checked settings and everything is up
I have the phone opened as we speak and the reciever cable is connected and the vibrator cable is connected too. I tried to use tweezers to see if i can unhook it but their on too tight so thats a good thing. The two orange dots on the volume thing.. the bottom on was slightly off so i put i centered it
Still nothing works. no vibrating no sound ( the person on the other line can hear me but i can't hear anything) but the phone works great.
Im so confused
The volume rocker is the button that 'rocks' back and forth to control the volume.
It has to be positioned right in order to push the contacts that lie beneath it.
Since your phone's apart right now, what happens when you hold the battery in it with one hand, boot it up, and press the volume button contacts manually? If they buttons themselves do nothing, then it must be that they lost their connection somewhere, you'd have to trace the wires and figure out where they're not connected. If they do work, then the volume rocker was just misaligned.
As for the speaker, it has to be that it is not contacting the two little contacts correctly. Look at the speaker and make sure it is sitting correctly in the housing, and look ffor any obstructions near the vibrator motor.
No i can't press down on the volume button ever since i opened it it hasn't fit back right. Doesn't make a click sound
and what contacts on the speaker should i be looking for? are they under the speaker itself? should i remove the speaker? Theres no destruction on the vibrator its looks though like its sitting kinda tight between that camera flash being there..the metal spinning thing on the end of it can spin 360 so nothing its preventing it from moving.
I also can use my headset and the sound and call works fine besides the going to the black screen and not responding. i also noticed my camera does not load up either. but that could probably be solved with a clean install of gingerbread nand rom
I'm hoping somebody with some knowledge of the HD2's innards can help me...
My vibration stopped working on my HD2. I found the plastic LED flash cover to be 'pushed in' (with the help of a couple xda threads I dug up). Others said it was an easy fix: Open the case and push that piece of plastic back into place.
I opened up the case to correct it. But after putting it back together not only does vibrate not work, but the volume keys, speakers (both earpiece and speakerphone), flash, notification led, and camera all don't work.
I obviously screwed something up, but I have no clue what it could have been. I was very careful. One thing I'll note is that when I pulled the case apart, the plastic volume rocker went flying. When putting the phone back together I got it back into place so that I THOUGHT it should work (it was seated properly and felt "clicky" for up/down movements.
But clearly wasn't just the volume rocker that was affected. It doesn't seem that I pulled anything else loose or anything like that...
But no luck, all that I listed above is non functional, and what I'm left with is a glorified 3.5 in tablet
Any ideas?? Thanks in advance!!!
Snapped a couple quick pics which may help:

Unfortunately when comparing these to other pictures of the inside of the HD2 that I found online, I fail to see any differences, or anything I could have inadvertently screwed up.
Most likely you screwed up(or disconnected from motherboard) somehow your main flexboard, but your picture are not usable for this, you should take off your motherboard+main flexboard from chassis to have a full view!
You probobly just disconnected a small cable. I have no idea of the HD2 innards but did multiple repairs of small stuffs and the flat cables hold in place by a plastic clicker pull out easily - just reopen and check them all, you should be fine.
Thanks for the input! I figured it's something like that, just one small cable. But I didn't even take off the board at all... The pictures show the full extent of the disassembly... Do we still think it's necessary to disassemble it further?
I checked all visible connections, but yeah, maybe I somehow yanked out something that is NOT visible. I'll try to check again today... In the meantime, any more ideas from anyone else? Thanks!
For al that to be not responding I would assume main-flex damaged or as mention before maybe connection to mainboard got moved during pulling cover !
Volume button can be troublesome, sometimes the little plastic caps come off but if it felt clicky should be good in that respect.
also be very carefull of thin spring metal legs that contact antenna pads on back cover, one near screw above & right of vibro motor looks a to be a bit flat. They bend easily & break easily too ...
Have u tried starting up the phone without the backing? I had this issue when I painted my housing the led cover was stopping the motor from spinning but if i took out the backing it works. So I just trimmed the led cover and now it works.

I'm nooby with regard to this stuff; I only attempted the repair since I read in a couple other threads about multiple self-proclaimed non-super-tech savvy people were able to open it up and move the plastic LED cover for an easy fix.
So what exactly am I looking for with regard to the main-flex? Where is it? I thought I wouldn't really see that unless I removed the board which I haven't done... is it still possible I knocked it loose or damaged it? I didn't think that would be possible since I ONLY removed the back cover (though it does take a slightly uncomfortable amount of force to do so, so I guess anything can happen...).
If not the main flex cable, is there anything else specific to look at which may be disconnected? It seems to be all the stuff at the top of the phone that fails to work (camera, speakers, vibration, flash, volume keys). While the stuff on the bottom (other hardware buttons, charging jack, headphone jack, etc).
THanks!
I have given up. After being stumped briefly how to hard reset the device without the volume keys working (I have Android installed), I was able to do it via ADB from the Android dev kit.
To ebay I go...
Hi,
I've recently changed the LCD panel on my Nexus 4, as well as the headphone jack (which includes the proximity sensor) - the screen was broken, and the headphone jack had very noisy output.
After putting it back together, I noticed that the proximity sensor wasn't working - during calls, it would constantly blank out the screen, and there was no way to unblank it (i.e. it seems to permanently think there's something there).
I took it apart again and noticed that the rubber gasket that fits behind the sensor is missing - it must have come off during the repair and gotten lost.
I tried putting some Blu-Tack behind it as a temporary fix, but no change. Now, I'm not so sure the new proximity sensor is working either.
Anyhow, my first question is, where can I buy a replacement rubber gasket? I've done a search online, and I can't seem to find it for sale anywhere?
Is it available as part of another spare part for the Nexus 4?
Cheers,
Victor
I had to replace the screen on my n4 too and fixing the proximity sensor was a pain in the ass. I had the rubber gasket but it was only working when the front panel was not attached as soon as i attached the front panel it stops working i.e. when in call the screen goes off but it doesn't come back on. So what the guy did was to scratch off the two holes on the top left from the inside of the panel. its looks a bit nasty but its working fine now. you might wana try to scratch off a bit neatly. like in a round shape.
I dont know if the gasket is the cause, but I know a case where this exact problem happens : its when u don't push the sensor well enough to fit in its place, cuz it should be near enough, or it'd blank the screen during calls. Try using a flat screw driver, and push the orange part where the sensors are well enough, that should do the work ( don't push haaard or I'll Damage it). I hope that'd help, cuz finding this gasket is hard. And this applies also for the guy who commented, cuz this is the case for him
