This is probably a fairly simple problem for you guys.
The connector on the bottom of my XDA2 appears to have come dislodged.
It has been getting harder and harder to get it to charge recently but with a bit of pressure in one direction it appeared to charge OK.
That is until my GF plugged it in to charge and now its totaly dislodged.
I think the socket has broken free from its soldered terminals into the PCB inside the XDA2.
Is there a quick fix anyone can suggest (I am a qualified Electronic Engineer and can solder) or is there a repair centre (hopefully near Newcastle upon tyne (North East UK).
PLEASE someone HELP!!!!

i have the same problem, but i got the pin chart from here, and wired a charge hole on the outside. now i can only sync via IR. lot slower that usb. for some reason, the solder wont hold the same plug the way the manufacter did.
good luck.

Pin Diagram for XDA 2 Connector
Where on here can I get pin connector.
Also where can I get tool to unscrew back off XDA2 so I can try and repair myself

1) use the search function. it's on wiki.xda-developers.com
2) you seem pretty unsure of yourself for a EE qualified engineer. Why, where does one obtain a torx screwdriver? A T6 will do.
We get this alot at work and use these guys. email them on

35 quid for a fix 72hr turnaround.
And no i have nothing to do with them
Possible solution
Hello,
I have the same problem and have managed the following solution to be able to charge the device with "a connector", its working perfect for me:
Note: You will lost some headset-functionality, I have tested that no internal components are affected, because the PIN used for power supply is cutted from the mainboard.
Disasemble the Device completely to have the main circuit board in the hand free from other coponents to be able to solder properly.
Buy a 4-contacts mini-jack connector (2.5mm)
Cut the Power Supply cable Power-Jack to replace it with the Mini-Jack (Image2 and Image4 )
Solder a cable to the 3 last ping of the base connector (Image1)
Cut (with Dremel for example...) one of the connectors of the Jack soldered on the mainboard (Image 3 and Image5)
Solder the cable that comes from the Base connector to the onboard Jack (Image 3 and 5) This is to get positive power from the Jack connector to the right place on the mainboard.
I hope this is enough, if you need more details please let me know.
Regards,
I have the same problem, though I am able to charge my qtek 2020 by putting it in one direction.
I am thinking about soldering a femal mini-usb port using pins 13,20,21,22 for positive power, 16,17,18 for ground, and 14,15 for UDC+ and UDC-. Has anyone managed to do this ?
Aw crap. Same thing's just happened to my XDA. The connector at the base has snapped. It's still connected (barely) but charging and data transfer won't work.
Is there any way to replace the connector with a mini-usb port at all or an alternative method that doesn't require me to send my phone out for 3 days?

Please help me out to find pinout for standard USB sync cable. I have Windows PH10B phone and I bought Qtec 2020 sync cable on ebay and unfortunately it doesn't charge and doesn't sync.
Thank you,

Hi,
I inadvertently damaged the pins where the USB cable plugs into and I am not able to use active sync any longer. My PDA will still charge, but I have no data connection. Is there anyway to repair this issue? I recall seeing a pin out diagram awhile back but cannot find it any longer.
Does anyone have any suggesstions? Thanks,
Chad
Can you actually visually confirm that the pins on the phone are damaged?
I thought I damaged my phone as well.
Now my phone only works with certain chargers and certain usb cables. I got my phone to sync by using a new cable.
I would try a new cable if you haven't already.
Hello, I've an interesting hardware question for you, xda community
My HTC HD2 falled down from the table while it was in charghing (so with usb cable connected).
The usb port broke, so I improvised a teardown to check the micro USB port pins on the motherboard.
I reach to reconnect power pins, so the phone charges correctly, but i'm not been able to find alternative points for data pins becouse of broken electric paths on the MB.
Now I'm searching for alternative points to restore totally the usb functionality.
Anyone (with a broken HD2 MB) can check where electric paths go UNDER the usb connector on the MB? ..or suggest me where I can find alternative points like factory usb testpoints on the MB?
many thanks in advance and sorry for my bad english...
Hey all! I have a pretty advanced question, and this might not be the best place, but I wasnt sure where else to plop it.
I have a project going on with my Nexus 7, and I need to interface with the OTG ID pin. Soldering a wire to the micro USB connector/ribbon is kind of dicey. I have found solder points to just about everything else I need, but I cant find a place to interface with that ID pin on the usb.
I know it goes through the main ribbon cable, up near the battery connection, but Ive probed just about everywhere I can think of, and cant seem to find a connection. Im GUESSING it actually winds up at a control chip somewhere. But almost every other component seems to have a solder point somewhere...
Any ideas??
Thanks!
Justin
EDIT: I wanted to be clear. I did search and read through the threads. Including the older one that is bumped on the first page. I get that the ID pin talks to a "chip" in order to tell it its in OTG mode. Im simply looking for a spot where I can attach a wire, that would be on the same trace as the pin in the micro usb port. I was able to solder onto the usb pins, but its sketchy, and the speakers make it tight. Im not really doing anything complicated, I just need to hit that ID pin circuit somewhere.
Hi,
I recently purchased a usb cable for my android head unit and the lead doesn't work. I didn't buy the unit so I don't know the brand etc. The unit was in the car when I bought the car.
I'm guessing the wires that plug into the usb connection are in the wrong order. I have no way of finding out the correct order. Does anyone on the forum know the correct order or even show me a picture of their usb cable.
I've bought 2 cables so far, neither of them have worked and they cost close the £100. It's very frustrating that I can't get them to work
Thanks in advance
What does the seller suggest and what happened when you tried that.
Also, with no information and detailed screenshots, how did you want help
When I plug in the usb cable and try any basic usb connections like phone chargers usb sticks etc. Nothing happens at all.
I've attached a screenshot from a product guide I found online if that helps.
If anyone knew which pins were for data transfer or voltage, that could help me loads.
Thanks
Measuring is the magic word. 8 pins will be connected in the original cable. (VBUS)+5V 2 times and 2x GND
...then you only have to find out what is D- and what is D+ for the data lines.
If you don´t want to measure: Open the magic box and have a look at the pins from the connector inside.
Just with your picture no one can tell anything. Each supplier does it´s own magic.
By the way... Connecting that wrong, may damage the internal USB-Hub and you can buy a new mainboard... just to mention. Trying around is not a good idea.
