i have to solder the mhl cable to the mhl ic. how to solder? i bought a mhl adaptor from china but it is not working since the first day 100% ( maybe 50% ) cause of the bad soldering. so i unsoldered it and now i need the mhl schematic or datasheets. which pin to solder i already know but there are two ground cables ( black and grey). can anyone fix my problem?
Details
the micro cable has to solder to the ic. but one or two cables i dont know to connect with which one. i think thats the ground not the black but the silver cable. if anyone opens his mhl adaptor so he can help me. i bought it from dealextreme. dx.com. maybe they will send me a new one may be not. we will see. but i cant wait till they will shipping. it will take at least 2-6 weeks. no more chinese products.
thanx folks

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

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?

pinout from wiki
http://wiki.xda-developers.com/index.php?pagename=Connectors
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,

can anyone please help, I'm looking for the connector at the base of an XDA 11, as mine is not working, I've been told that the connectors off the ipaq 3800 & 3900 will also work on my XDA 11, so does anyone know were I can get hold of one...........................
go to e bay type in xda and there are lots cheep
Do you mean the whole base unit or the mains charger piece.
RE: connector
Hi wessy123,
If you look at the bottom of the XDA2 there is a connector plug to charge the phone in the dock also to Activesync the pda to your comp, that's the part that I'm looking for as mine is goosed, can you help ? have you got one spare ?
Put XDA on e-bay there are loads of cheap charge/sync cables i buggered mine cost £3 to replace it.
Its not the sync cable he needs, I think he needs an old xda or ipaq 3800 series motherboard so he can desolder the connector and resolder to his own motherboard.
re: connector Plug
The part that I'm looking for is the Connector Plug itself , that's connected to the motherboard, if you look at the bottom of the XDA2 you can see the plug.... inside the plug is a row of very fine connectors , on mine they are broken.
I can sell you charging/synch connector for $20 US
connector by itself so you don't have to use soldering tool to take it off the ipaq motherboard
PM me if interested
I just bought the HTC 3-in-1 adaptor from ShopBrando HK. I am using it in the car with the Brodit holder to have both charger and 3.5 mm for the car stereo aux input. I am modifying the holder (removing the charger pin for the adaptor 11 pin).
The problem is that the adaptor's wire is too short. I want to hide the adaptor somewhere in the car and a longer wire is needed.
I am thinkng about
a) Use and extension wire ( if there is any) Is there an extension cable (male to female -11 pin usb) ???
b) Cut and extend the lenght of the wire.
What is the wire used?? If I cut the wire to extent it, what kind of wire should i ask for?
Thank you
This is exactly the same problem I am facing. Can't find a ExtUSB Male to Female extension. But I would be up for trying to extend the cable if I could buy some. Hopefully someone will answer.

Just clip off 1/2 inch and take the sample with you to the store to show the sales people. At the same time, you should get the proper connecters to splice the wires together.
Does anyone really need to extend all 11 pins for both audio and power, or just power, or just audio?
Anyone know what wires from the USB would I solder to make my own adapter?
I don't have a CC at the moment and can't order overseas. Which of the 4 wires would I solder to the audio plug, which I have?
Has anyone used these with AKG 240's?
thanks in advance!
kaiser don't have a mini usb connector
it have an extUSB which is a mini usb connector
together with analog sound pins on the other side
of the connector
you can buy extusb converters for a few coins
however one can't make an miniUSB headset at all
unless the headset contain an usb soundcard and the
device support usbHost which kaiser don't
just get a dirt cheap conveter
but if you must do it youself then here are the pinouts

I have a spare adaptor. can list via feeBay so you could purchase from your own country.
Would be cheap (just enough to cover costs)
Just a thought, if of any use to you pm me.
Hi all
Any reason why an after market car usb adapter isnt able to recharge the streak?
Or it there one that can ?
It's because it isn't putting out enough power. I read a post about this a while ago, but forgot which forum, basically to get it to put out enough power you're gonna need to connect the two middle pins on the adapter. If it's easy to open then do that and solder the two middle pins and you should be good to go. I have a belkin one that I had to do this to
Sent from my Dell Streak using XDA App
Hi ipguy,
Think fone_fanatic was refering to this thread: http://forum.xda-developers.com/showthread.php?t=719815
Like he said, you need to solder the two middle pins on the USB connector so the phone can register it as a power source, but you have to make sure that the adaptor outputs 1000mA, most adaptors only output 500mA and won't work with the Streak, think someone said that they could overheat/malfunction if tried.
I had the same concern... And I'm not willing to try soldering anything I just ordered the accessories from dell.com I should get it by next week.
