HTC HD2 High-definition Motherboard Pictures

Hello guys. I need high definition photos of HTC HD2 Motherboard. I need to check one SMD part on motherboard because I think I accidentally broke one part on it. It seems like there is one missing part but I am not sure. So if anybody can upload really high def photo of motherboard it will be great. I searched google and forum here but its not enough to zoom in on that place.

Nice one wouternet but can you also take the picture of the other side of the board? But thank you anyway i will need both sides of that board

It would be easier if you said what part your looking for
Don't mind the black stuff, I used a marker to mark this bricked mainboard

i am sending a pic of that place. its a small smd probably but i am not sure . the location of that part or better say place is very near to the edge of board it is the last solder point to the 3 gold connect points i am not sure for what they are used for. probably for extended battery? i just need to know if there is som smd part or not. because it looks suspicios on my board and i think that this is why main speaker is not working on my hd2 since i disassembled hd2 to repair vol buttons. flex cables are ok i already checked them because i remember when i bought phone the sound was not working because main flex was not properly pluged in on main board. i was very careful whem i was dis and assembling phone . i dont understand why aound is no longer working.

Nah there is nothing there. At least nothing that can break off easily. I'm sure the problem is somewhere else.
Is it the earpiece not making sound or is it the speaker on the back?

yep it is back speaker that is not working. I dunno what cause that problem with no sound

Well the problem should be near the GPS board... Or in the rear shell....
check this: (No need to take the speaker out) http://www.ifixit.com/Guide/Installing-HTC-HD2-PB81120-Phone-Speaker/5605/2
And this is where it connects: http://guide-images.ifixit.net/igi/IKePYgHa1GxX1vZF.huge
It's left from the camera, between the Camera module and the where the white wire connects to the board. There is should touch the 2 golden squares.

i will check that place near gps. Or maybe the speaker is broken. I will try another one if that help. I will let you know later when i fix it. Thank you wouternet.

Well you was right about the place near GPS where speaker is connected to the phone. The problem was there. For some reason one of the golden square dont work anymore lol. Weird huh. So the solution I have found out was to connect that non-working golden square to the little golden O point between those 2 golden squares.
Here is a picture
Selected red places are the points that are working.
So i connected non working golden square to the O point between those two golden squares with solder and after that woalaa. Speaker is working.
I still dunno why this golden square caused the problem because it looked like it is solidly attached to the board. But anyway speaker is working and I feel peacefully .
I will edit this thread as a guide if somebody needs it. I also fixed camera flash light because everybody who dissasembled HD2 know that cable from camera flash light connected to the mainboard is very fragile and it can be easily torn out of the connector and if you want to put it back into the connector it is really painfull and not always work so I decided to solder it to the board on camera flash light.
Here is a picture how I did it.
I connected those coloured cables using solder to the golden O points on camera flash light board as it is shown on the picture. Woalla again it works. Its free if you have soldering tools and some experience with soldering .

Thanks so much for sharing your solution.
Exactly this hint has given the life back to my phones speaker.
I used very thin copper wire to connect the 2 points.

Please, I need a photo of USB motherboard zone area, zoom in,

motherboard htc hd2 t-mobile
I have a HTC HD2 from T-Mobile USA, which broke my motherboard. if anyone has any idea if it matches a motherboard in hd2 hd2 for Europe which my phone is t-mobile. I mean plugs, screws, joints ... etc.. I think that maybe easier to find the motherboard but if I search for a motherboard to hd2 t-mobile phone.
please if you can help me with any information any connoisseur, is welcome or if someone has motherboard for sale in working condition with no problems (not boot the, to lock up, etc ...) to me leave message here
sorry for bad eanglish

Anyone take the speaker out of an LG WCP-700 yet?

This is a picture of a circuit board from an LG WCP-700 Qi charger. It makes a very annoying beep, but I can't figure out what is making it. My best guess so far is the part labeled 331. Any help would be appreciated.

Is the beep that loud? If you find out, be sure to post it here. Mine is on it's way.

That looks like it. I'll certainly take mine out when it arrives in a few days, if you are too afraid to yank it wait and I'll let you know how it turns out.
I'd rather have a dead charger than a loud annoying one

Might want to check this out. Someone stated that they took it out and it's dead.

I have the same question, I got the case open expecting this to be easy but I'm not 100% sure what to pull off the PCB. I think you are right that it has to be the part labeled 331. There is just not anything else that it could be.
That said I'm not willing to pull it without some confirmation. Maybe somebody here with more EE experience can tell us for sure.
I don't get my nexus 4 until tomorrow, maybe once I have it I can get the charger to beep and listen for where the sound is coming from.

Apologies for being slightly OT (although I'll be looking to do this when I get mine).
I'm struggling to find a supported voltage range in any specifications for this pad - I'm UK based and need either an adaptor or convertor depending on the range.
Could someone who has one let me know what the specs are please?

How did you get it open??? I've been trying for a week now and have all but ruined the bottom ha! A "How To" would be appreciated!

The 4 little rubber feet on the bottom pull out and there are 4 small Phillips screws underneath.
I had to use a small screw driver to pry up on the feet, it felt like they might rip but they all came out undamaged. Once those screws are out the top and bottom are still held together by a couple of snap-tabs in the middle of the long sides. I was able to get them apart with a little prying and again nothing broke even though it felt like it might. The PCB is held on by 4 obvious Phillips screws.
Sorry I don't have any pictures and can't take any until after I get home from work later.

OK, mine is different then... I got it from Amazon and its a Verizon one and the bottom is all one solid rubery unit. I saw the 4 posts with screws when I pry it open but couldn't get to the screws.
Thanks!

Instead of pulling it or jacking up the PCB trying to disconnect, could you maybe just drown the thing in some sort of epoxy? if not muting it, may at least muffle it some

Check the ZENS Qi wireless chargers, no beep and work great!

I've tried putting my finger over different parts of the PCB and the letting it beep, including "331", and nothing I do lessens the volume. That's why I'm baffled on what part is the actual speaker.

The part labled 331 looks like an choke/inductor to me. I wouldn't remove it...
edit: do you have a picture of the other side of the PCB?

The only things on the back side of the PCB are the two LEDs at the top. I am beginning to think that the sound is coming from the coil itself, like it is performing double duty as a charging coil and as a speaker coil.
BTW, I got my phone today and can confirm (as has been said elsewhere) that this charger works perfectly for charging the nexus 4. Well... expect for the loud beeps.

Just for reference here are some pictures of my charger, so that you can see the screw locations. Mine is also Verizon branded and came from amazon.

Awesome, turns out the plugs were there the two I had tried to pry out tore making me think they did not come out. So, now just to figure out where the beep is coming from!

[Q] How to open the Nexus 10?

I want to open my N10 up, but I really don't know how much force to be using to separate the back from the screen (seems like it would require an extreme amount of force).
I have a suction cup attached to the screen, and I have the screw off the back. From there, I assume I would start at a corner and just press it downward to try to get the back off? Should it require a lot of force? Does the back bend, or should it?

Do a search, got to be videos on you tube.

Only thing I can find is the PowerMedic teardown, which doesn't explain how much force should be needed still...
I'd rather hear from someone personally how hard it was to open their N10.

Found it
Hmm, I'll have to see if I have a separating tool, but that doesn't look like too much force was used at all.

Finally got it open. Was a huge pain to do with a credit card (basically destroyed it mostly), but I started with the top-middle edge, and worked my way around from there. Biggest pain was to get the bottom edge off, but I managed to get that off after a while.
So, I just noticed that my Pogo connection area, there's a pin broken. From left-to-right, it's the 5th pin. Why is this?

Do you mean on the inside of the N10 there is a pin broken? I looked at those powerbook medic photos which its hard to get an angle on that area, but it didnt look like any of the inside pin connections were missing, so are you saying it looks intentionally not connected/separated?

It's like a 3-piece system in the Pogo cable area. The N10 shell has the 5 pin area and has metal contact sheets on the inside for those pins. The N10 itself then has strips of metal I think above metal contact points. The strip of metal that should come in-contact on the N10 itself is cut-short on the 5th pin.
Probably not the best explanation though. I think I saw a post on the Pogo cable thread of someone mentioning this.

I know there was a post about the pogo charger that included pictures, and in the picture one of the pins was either missing or shaded. the discussion assumed it was missing and gave theorys on why. (all perfectly reasonable as I remember.) BUT I just got a pogo in the mail a couple days ago and, at least this vesion, has all its pins. im guessing there is a couple ways the pogo "port" could be utilized, so a variety of combinations would certainly make sense.
but as for that cut short you're talking about, does it look machine done? like if its a ribbon-like material does the notch made in it look perfectly made such that it was done by machine? or does it look jagged or snagged? if it looks machine made Im sure its intentional. if it looked jagged or snagged Id be concerned that is on accident.
EDIT: i ask/say "ribbon like material" but same basic thought process for me re: metal extensoin posts - does the "cut" look like it was done with some sort of grinding device that would leave the pins as "not sharp" or does it look cut like when you flex metal a bunch and it snaps or if you use wire cutters how it leaves a jagged edge.

Swapping Motherboard

Unfortunately I dropped my xt907 (with some serious force) and smashed the screen.It appears that the phone itself is still functioning because lights are flashing, its making notification sounds and when connecting to my computer via USB i can access all my files. Since i dont want to buy a new one and be handcuffed with a locked boot loader I'm going to attempt a repair. Does anyone know if putting my motherboard into another phone (maybe with a bad ESN) will bring my phone back to life? My other thought was to salvage the motherboard, battery and camera and just install them in a brand new LCD screen, digatizer and backing. any feedback would be appreciated!

Just pick one up off Ebay or something and swap the screens... Its rather easy to do in my opinion... I usually grab one that's water damaged...

Btw how is KK soak bld hunting getting on?

I wish it was as simple as replacing the screen but the backside got all messed up too. I managed to get the board out but in doing so there was a tiny metal hinge looking thing that broke off the backside of the board next to there the power plug. I'm sure that completes a circuit somewhere so I guess my little project is over. not good.

Sent from my XT907 using xda app-developers app

here are some photos. I have circled the area of the motherboard that was chipped. In motherboard1 the piece that broke off is in the photo as well. In the backing photo I circled the area that may be a contact point to complete a circuit.

Yeah that looks done... It may just be for the wifi but doesn't look like it can be Jimmy rigged ... I was thinking maybe a touch of foil on it but I don't see any tracers to make the connection

Yeah i think some solder and a a little luck would be my only shot. Ill probably just try to buy a used one that someone already unlocked.

That's for the LTE Rx antenna. The motherboard will probably still work, but you will have diminished LTE reception.
That motherboard might still be useful for someone who is using their phone on GSM networks and can't use LTE anyway.
I might be interested in it if you'd be willing to sell it real cheap.

Thanks for the explanation. If I end up selling I'll let you know. Do you think the antenna can be reattached and become fully functional again?

Hard to say, but in my opinion, the answer is YES. I don't think you'll have any chance of finding the broken trace, I sure can't see it in that photo and I'm guessing it's not visible. However, I bet one of those tiny components near where it used to be was directly connected to it. You would need either a wiring diagram or trace an undamaged motherboard with the ohms setting of a multimeter to see if any of those components were directly connected to the terminal. You could then probably reform that gold terminal with tweezers, and solder a very, very tiny wire between the solder end of the appropriate component and that terminal and use a good strong epoxy to glue the terminal back down to the board in its correct location. You'd need a really good pencil-tip soldering iron, really steady hands, and good soldering skills to do that kind of micro-soldering.
I'm thinking to part out the RAZR M that I bricked over the weekend. If you're interested, I can test my board to see if any of those nearby components have continuity to the terminal.

Not sure if you're still wanting to fix it, but I pulled my bricked RAZR M apart today and saw this is a pretty easy fix.
That terminal connects directly to the lower of the 2 black SMD components. In fact, I didn't notice before, but in your pic there is still some visible trace connected to it. Should be pretty simple to epoxy the terminal back onto the board and solder a short piece of wire onto the remainder of the trace.

I do want to fix it and will be giving it a try! I'll post the results

Good Luck.
I made a Mobo Transplant also once.
Got a Broken LCD phone which was damaged before the OTA (that locks our BL)
And took that and swapped it into mines =)
Now i have a good Phone with a Unlocked BL
And sold my old one back out for same price =) Win Win for me.

What is this part??

I can find every part except this one and i dont know its exact function .
The flat cable that is above the camera in this picture can anyone list the part name so i can order another since i bent this one creasing it as you can see and would rather not have to take the phone back apart once i put it together this time.

It's the "frame" usually sold with the display assembly. The frame is the structural part that holds everything together.

No bro the flat cable thats above the camera. maybe i should say to the left of the camera in the picture since the picture is sideways

that little silver box on the cable is a microphone, so it would be a microphone cable or "flex" as its called. search ebay for "v20 microphone flex"
