Hello!
I decided to ressurect my HD2 with broken USB port. I bought new one port and soldered it. The problem is that DATA pins are not working - only charging.
USB points are damaged. I tried to see and solder where they are placed - but no seems no luck
Please, can you give me the closest points, that I can use as solder points for USB DATA? Maybe, schematics or diagram?
I found pinout for processor - but... it's too HARDCORE to solder to processor points

These images worth more, than any words. I needed just last image from that site to understand everything.
I will try to gather all information to some kind of post.

There isn't much in the text and haven't done it myself, but I'll translate that text from the site.
[photo on the side]Hello,
I'd like to show you few photos from replacing, or more like fixing a torn out USB port.
The phone came to us with symptomps of not charging, and after opening it we saw this:
[first photo]
As you can see, not much from the port was left. Torn out GND fields /*not sure about the translation*/, broken - torn out signal fields /*again not sure if fields is a good word*/ of the socket...
[second photo]
...quick preparations and let's begin:
[third photo, zoomed in]
This is how the board looks after initial preparations. Torn out ground fields I had to replace by stripping soldermask, so we could solder the new socket with some stability
[fourth photo]
The holes in the board are cleaned out, the next step was to tin the entire ground field and soldering the socket...
[fifth photo]
Of course the phone can't be charged yet, nor it will communicate because the socket is soldered only to GND. All we had to do was to connect to the signal lines...
[sixth photo, zoomed in]
And now let's test it.
[seventh photo, with HD2 connected]
After testing the communication and charging, the socket was covered with glue and left to solidify. Without glue, the port would probably last about a month because of the weakened board from the last tearing out. After solidifying the glue is a protection from tearing out and lets us enjoy a fully working phone

Thanks Spaqin, that seems a very good translation & far better than google could do. Use of field may not be best choice but certainly descriptive enough & works for me. Have saved your translation & the images to a word doc as could be good reference archive for anyone doing same repair in the future as more repairs on mainboards are a necessity due to age of device & lack of easily found donor boards. Many thanks ...
On a second though, 'area' instead of 'fields' would be probably better.
Glad to be helpful though : )

Hi,
I have an XDA1 and want to get an XDA2.
However, we aren't allowed cameras on site at work, and despite a long email conversation with the security jobs-worth where I volunteer to super glue a metal plate over the lens and the likes, I'm not allowed to bring an XDA2 to work :x .
So, does anyone know how difficult it would be to open up an XDA2, unsolder and completely remove the camera?
Thanks in advance,
Muddy.
If you look at this pic, it looks like just unplugs. But will they just not still disbelieve you?

Did you take this picture yourself?
Did you have to strip the XDA2 down much?
Cheers,

No I prefer my unit in one piece. Its from the wiki.xda-developers.com and the thread http://forum.xda-developers.com/viewtopic.php?t=5002
Here is a pictorial step by step guide to opening the unit.

More Pixels???
Actually, if you can remove the current camera, I wonder if it would be possible to put a better camera in its place..?
Opinions anyone?
It may be possible to plug it in, but I'm not sure the api's could handle it.
This module here appears identical to the xda's, but is 1.3 Mpixel.
From here:
http://www.aiptek.com.tw/english/product/modules/module_desc.htm#2
Sounds like a research project for PPCtechs

This is what happens when low-paid morons get to decide on company policy. If you were going to spy, you'd just bring in a clandestine camera (many are so small they are undetectable without a strip-search).
As I said, if they dont believe the metal plate, why would they believe he removed the camera?
Surur
Nice 1.3
Hmmm Very keen on looking into getting the 1.3 installed ,Any one know of an importer for the cam ?

Carlos,
Sometimes it is best to hide in plain sight.
If you get caught with one of those devices or using it - kinda limits your excuses. If you, like everyone else, have a camera in your phone who would notice you. Now, your camera might be modified by someone to take better photos, but they would never know.

hi
thanx alot surur
i'm so interested in the 1.3 mega pixel camera module and i have some questions about it :
can i replace the one inside the i-mate with this one ?
is it going to work fine with the i-mate ?
from where i can buy it ?
and please i need any information about it
another site about it:
http://www.worldlingo.com/wl/transl...iyota.com/product/cmos/sxga.html&wlg_table=-3
the i-mate will be the best device if i can use this cam
AMmorsy
The built-in-camera is this one: http://cp.literature.agilent.com/litweb/pdf/5989-0391EN.pdf
I know nothing about PPC programming, but wouldnt it just be like updating the drivers for the never camera over the old ones? Plus a little more. I am sure someone could make some money out of this!
Why did this discussion stop?
Did you not have any success, or did you damage your gadget?

Hi, I need motherboard technical sheme for HERM100.
When I was repering thread near jog wheel, unfortunatly I u brushed some rezistors by drill. So I need to solder them. I don't know how much OHMs they need to have.
Those elements are sytuatet near OK button and some two grey bigger integrated circuits, one was grey , one was black.
Enybody knows what parametrs they have?
Enybody have technical sheme of HERM100, where can I get it?
HELP!!!!!!
the little grey ones and the little black ones are different, and unfortunately there is no way unless someone has the board schematic which is highly doubtful as companies don't tend to give out that kind of information, your best chance is to .... buy a new board off ebay as at this point warranty void!
and if you did knock an IC off the board it more than likely lifted the tracks, and that is a big Game Over! as these are multi layer boards so there are tracks under tracks, and pads interconnect to tracks under the board.
Grey = possibly capacitor
Black = most likely a resistor
Hey Mr. Spook
maybe you could take a picture of the damaged area, and post it.
If your PCB is not totally ripped, we could do some measurements and try to find the right values for the missing components.
At least this should be possible for resistors.

Mattnokis is right, these multilayer's could be destroyed by ripping of a pad, at least the connection between two components could be damaged permantely.

I just measured the value of the black component using a multimeter.
It seems to be a 10 ohm resistor.
Good luck for fixing this!

I am a proud magic owner but as some users have found out like me, it is a slippery fish when it comes to its glossy covers. At first I did not use the slightly camp white leather pouch the magic comes with and now I am regretting it.
The phone has now acquired some bumps and scraps. I thought to my self I would replace the phone covers. So I ordered some on the bay and got them sent to my office.

I hunted down the service manual for the phone. (If anyone is looking for this I have it uploaded here).
I merrily went to work disassembling it bit by bit until I came across a slight problem. Now I have uploaded pictures to illustrate my woes.
First the battery cover was completely rubbish, the brushed steel plate that surrounds the camera was dented and also had the metal grate missing which usually covers the speaker. This was not the biggest worry however.
When I dismantled the phone I got to the stage of separating the the front cover from the middle part of the case. Now as you can see on this picture on the back of the mid section of the case there are two white label like stickers which have gold contacts on the inside.
There are more of these labels on the antenna at the bottom of the phone also. They make contact with gold contacts on the phones main board. I assume the bottom antenna is the gsm antenna and the the contacts on the top are for the gps. I could be wrong though this could be the other way around.
The problem is these label type contacts are not present on my new case mid section as I have shown here in this picture.
Has anyone else had any experience with changing the covers on this phone. Or if these contacts are important or even if its possible to find these labels so I can fit them to my new case.
Cheers for any help you can give me, or if any of this info is useful to you also if you are in the same sticky situation.

bumpity bump!
you could try contacting htc, maybe someone could be friendly enough to point you in the right direction. also email the vendor you got the parts from and say the housing is unusable. I ran into a similar problem with my g1, which ended up having the housing all jacked up.
Sorry I can't be of more help.
Thanks for your help, I will see if I can find out anything and post my findings.
Vale
Just curious, have you tried removing the stickers? Would they just rip apart? Is that the only complication?
You might be able to find a bricked/waterdamaged magic and change the housing without all the drama.
hey check this out too, it may help:

Connected external antenna to ipaq hx4700. Antenna was from a Belkin Mimo router that had the right size connector (very small IPX connector)
First removed existing connector/wire on wifi board that leads to onboard antenna, then connected external antenna wire to board.
Antenna was omni-directional so there was not much difference in signal. Might try making a directional parabola to fit around the rubber ducky and test with mini stumbler.

DIY BGA RAM upgrade...hmm, now where did I put that toaster oven.
That Chinese site "translation" says:
The ninth step, the new memory chips placed on the chip welding position, alignment solder joints, is very simple, because the chip is surrounded by a white frame, as long as the alignment position on the list.

I'm surprised how much space there is btw the spots on the BGA chips.
I wish I had a rework station. Has anybody else tried this? I know about PPCtechs, I'm talking DIY.

Welcome to xda-dev!
If anyone's interested, I found an excellent site with alot links to technical info on the hx4700. It's in Czech so Google translate. Links to chips, antenna, etc. Best tech info on 4700 I've found so far.

Hi all,
I have got an Ericsson F3307G, is there any way to add it into Acer Iconia Tab A500?
thnx
Good question - I don't anyone could answer that without actually cracking open the tablet and having the knowledge to decipher the internals.
Normally, I wouldn't think it would just be a simple, solder it in place and call it a day situation. But, one never knows.
Did you see this guy rip open his? On androidtablets net, post- 13577-whats-under-hood-acer-iconia-tab-a500.html. Sorry I would put up a proper link but I am a newb.
I wonder if that little white strip in middle leftish is an internal sd card?
I have seen a tear down, though I don't know if its that one.
Either way, I'm not knowledgeable enough to know if that would work or not.
Be interesting to find out.
thanks to all for replies. What i search for were internal pictures.
In particular, this:

it should need to solder a mini pciexpress slot on those pins on board (with sim card holder).
this is the thread:
http://www.androidtablets.net/forum...77-whats-under-hood-acer-iconia-tab-a500.html
Yep. That's the image I saw and I doubt it would be just a simple solder job. Why not try it?
EDIT
Besides, it barely looks like it's got any chips on that part of of the PCB and you'd need to add a connector point for the SIM connector to slide into. I think if you got that far, it could very well that the board itself will not accept an after market part like that or that they remove all functionality of that type for wifi models in a future update.
anyway it's bad idea, it's difficult to install beacouse sim card holder will be in wrong direction ti insert sim card if it added :/ the correct way is to buy the a501 version.
thanx to all for your reply and to drive away my dubious
I think the Mainboard is the same for all A5XX model so they just didn't put the
- miniPciE port
- controller O21 and D3 position...
so far I think that will be... risky, not sure to work, and not worth the time to try to SOLDER anything.... sadly.... I was really expected they put the modules functionnal but just not the 3G Card... that will be so nice from ACER...
----- hope the 3G on USB will be ripoff
I heard about some kind of Wifi boxes you put the 3GDongle on it, and all your HomeWifi got internet via 3G.... is that could works?
