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?

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

Thanks to HTC and the garbage job they do baking the electrical components in their phones I am looking for a HD2 mobo or someone who can do some PCB repair and at least get my mobo charging again. I have dumped money into a new digitizer and lcd, front keypad and mobo main flex cable and the main problem that caused me to destroy all those parts in the first place (micro usb port) still isnt fixed after my attempt at resoldering it to the board. Anyone? Thanks ahead of time, I've lurked here for a while and never really posted so I cant look in the classifieds I take it.

Are you by any chance located in the New England area? If so, I may be able to help you out. We would have to meet up somewher. If not, good luck finding some that can solder contact points that small.

Unfortunately no, Im in central Florida
I'll post some pics later when I get home from work, when the port broke it lifted the traces for pins 4 and 5 which I understand are the ground. Pin 1 is apparently the +5 volt pin. Thats all I need, I can do without being able to communicate with the phone via PC. I really have no reason to use ADB with this handset and any ROMS can be loaded via my SD reader/writer in my PC and just reinsert the card to the phone after.
hi !!!! im after some info on my desire z. my brother brought the phone brand new and 5 days on having the phone ,got drunk and accidently dropped the phone down the toilet !!! ( idiot ) the screen was damaged and needed to be replaced ,the phone would switch on but no display ! so i brought the phone of him for £20 ( bargain ) i then found a place in china that sell the screen for £30. i waited 2 months for the screen to come and in contact with the person they told me that it had been posted but must have got lost in the post. he gave me my money back as i decided to get 1 from the u.k and 5 days later he refunded my money. 4 days after my refund the screen came = ). so i searched and found a video on how to take the phone apart and decide to fit the screen myself with no problems. now i have the problem that when i make phone calls ,people cant hear me =( i have tried my voice search and voice recorder and my phone does not pick up my voice up so i know the mouth speaker does not work !!!! my question is ,what part would i need to replace for my mouth speaker to work ??? any advice please ?? thanx for your time

thanx for your reply ,any ideas where i can get 1 from and how much it will cost ???
o,k ive searched around and can not for the life of me find this part !!! can any body help me please ?????
its part of the main flex cable, easily forund on ebay or amazon for 35~40usd. if you find one that comes with the whole chasis it will make replacement easier as you won't have to glue/unglue anything but its harder to find and most certainly will be used
good luck!

I have to check, but I don't think you can replace the microphone on it's own. It's part of something, I believe on the screen portion of the phone. I'll have to take a look and see where it's located. I'm not sure, but I think it's part of the flex cable.
demkantor beat me to it.
Maybe everyone you speak to is deaf
Velcro. What a rip off!

thank you so so much =) my next question is ,which flex is it ? the navi key and flex or the slider flex ??? sorry if thats a dumb question ?!? lol
there is one big main flex cable for your phone, and then small ones connecting the sdcard slot, keypad, etc
you need the big main one, if you take your phone apart and folow the main flex down to where the mic is (look @ the whole on the bottom of phone directly down from back arrrow) you will see the mic sitting in a piece of rubber. it may be possible to solder a new one into the flex but I feel it would be extreamly hard. just buy the whole big flex and it will come attached to it

thank sir ,you are my saviour ! ive found 1 ,£20. thank you so much =)
As many have noticed Asus left the mount for a rear facing camera inside the nexus 7 even though they later took the camera out. My question is, what would it take to install a camera into that mount and get it to run? My guess is all it would take is the right camera and a connector that could be installed into the board beside the camera mount where the old connector was. Of course a hole would need to be cut into the back cover which may interfere with the nfc antenna. Or would it? Would the firmware of the device need to be messed with, or would the camera work with any camera app like normal? If you have any ideas on how this could be done please reply. I would like to try this but it may be more difficult than I'm thinking.
I haven't taken much time to look at the inside but I plan to put some LEDs between the speakers so it will glow. So I'll look tomorrow but I don't think there is a place to connect the camera.
As far as the antenna, if your careful enough you could lift it up and move it. And just solder a wire on it to run to the connectors
But this is if you could find a camera and get it to work

I believe there is a spot on the right side of the mount where a connector was supposed to be soldered in but was left out. I wonder if Google or Asus would tell us where to get the connector they originally planned to put in that spot. I doubt it.

Yea, it's not really worth it. He parts would be expensive
Hense why they left it out, to make it cheaper

Replacement camera modules are surprisingly cheap. From $10- $40ish. You would just need to find one with the same connector and many seem to have one or an other connector. So if you could find the connector and attach it to the board finding a camera to connect to it may not be too difficult.
My screen of my HD2 had a pixel fault, it had a purple circle on the middle of the screen, so I decided to dissasemble it.
Well, the phone inside is very confusing, I looked at the screen part and I couldn't see anything.
I re assembled it, and it won't power on now.
Is a phone so sensible when I touch it inside its gonna die?
I successfuly changed the digitizer of my Wildfire S so I thought the HD2 wouldn't be a problem.
Is a phone so sensible when I touch it inside is the chance to kill the phone 90% or what?
I need quick answers.
Thanks!

Hd2 is delicate & not easy to dismantle without experience & extreme care.
Most first time strip-downs by people with little or no experience result in problems like yours.
Check out the threads on dismantling guides & also videos can be found on youtube.
Check all connectors to mainboard are inserted correctly & also check basics such as battery pins are straight & not misaligned during dismantling/rebuild.
Initial screen issue sounds like lcd/digitizer needs replacing.
The very tiny camera holder on the Main Board broke, its Not a important thing its Theres thereby the camera stays at place.
While taking off the screen i accidenty broke the screen BUT ITS ALMOST INVISIBLE.
I lost some screews and the chassis won't fit in the houses.
I was going to fast cause I'm 14 and my parents didn't allow me and I didnt want them to see it.
But problem is, i lost the cable adapter for the phone vibrator (LOL)
And i lost the board screews so I used the screews of the phone case.
Where can I get new screews?

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.

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.
