[Q] can I repair a plug on the motherboard ? - Desire HD Q&A, Help & Troubleshooting

Hello,
When replacing the LCD screen, I broke a record.
The plug is used to connect a cable that connects the two part of the motherboard (near the GPS). If I can replace the plug with wires ?
The current cable 4 wires: (black / green / brown / red).
The photo is attached to my message, the broken plug is surrounded by a red circle.
Thankx

In short, no, the PCB itself is pretty much destroyed, you can try to solder wires though, but it'll probably just cease to work

Hello,
Does this plug is for the GPS ?
I do not know their starting points soldering ?
Thankx

Serial COM port in HTC proprietary USB

I found special solutions - possibility to use COM ports on most of HTC devices
You have to use spcial Nokia's cabel DCU-5 and 11pin miniUSB HTC plug .
After cutting it close to Nokias plug you can find four wire.
Please chceck voltage on connected to PC USB .
White ( earth)
Red 0,15V
Blue 2,34V
Green 0,49 V
If you have the same voltage it's mean
Blue is TX
Green is RX
So you can find in HTC miniUSB possiblity to finnd Tx and RX as on drawing .
To connect with PC you need to use Nokia's driver for virtual port .
Maybe better solution will be use of max3232 circut .
Very good!
do you know the corresponding colours in htc's extusb headset cable? i mean what to connect the dku-5 wires to in the extusb cable, because i don't have breakout board.
According to drawing http://www.tracyandmatt.co.uk/blogs/media/EMU_pin_config.png
I founnd colours only for audio pins in ExtUSB :
Data pins has to be standard colour code , I think .
So please chceck
A = GND colour Black
B = NC
C = +DATA colour White
D = -DATA colour Green
E = +5v Colour Red
Audio pins
1 = +Mic colour White
2 = +Right colour Red
3 = Switch colour Blue
4 = Gnd Colour Red-Yellow
5 = Mic Gnd/Antenna Colour Yellow
6 = +Left Colour Green
What about charging?
Hm, so this means that if we use this scheme to connect a serialport to the miniUSB-connector we cannot charge the PDA at the same time unless we put separate charging-wires on the +5V and GND...
I have been in contact with HTC about this because we are desperately looking for a solution for a problem we have. We use HTC Advantage 7500/7510 who have a USB-host built-in and using the VGA-out-multi-cable that comes with the 7510 we can get a serialport using a usb-to-serial-connector, but the one that HTC makes is a bit too big and we want to build the connector in to the vehicle cradle.
Your solution might actually work, we need to test this. Huge thanks for the info!!!
Couple of notes...
Instead of hunting for voltages on the various wires which may or may not be color coded the same way, it might be easier to look at the following page:
http://jethomson.files.wordpress.com/2010/02/ca-42_dku-5_pinout.jpg
And then (if you've got a continuity mode on your meter), just strip the end of the garbage half (dku-5 connector) of the cable you just cut and tone out the pins to figure out which color means what. It certainly made it tons easier for me. In my case the RS232 RX, TX, and GND were White, Green, and Red respectively.
Also, the drivers listed above may or may not work for you, depending on who made the cable you bought. I purchased mine on eBay for $4 US. The following table shows a list of various DKU-5 cables and their related linux driver (which may help you discern the manufacturer):
http://wiki.gnokii.org/index.php/Cables#DKU-5_and_CA-42
I attached my cable to a linux computer and ran "lsusb" from a terminal. This told me that my particular device was an ArkMicro Technologies 3116... Once I found drivers for that device for Windows XP, I was fine. I'm not sure how you'll figure out the device manufacturer from Windows, but someone here will figure it out
So if i modify the Nokia Cable, i can use it as serial wire to debrick the HTC G1/G2 ?

Damaged USB Port?

I was charging my GNex on a Kindle cable. My foot got tangled and it dropped onto the flaw. Now it won't charge properly (very intermittent and only need a nudge to stop) on either of my two Kindle cables. It will charge ok from a different cable.
Have I damaged the port? Can it easily be fixed or will it need to go back?
Just bent the bit inside the port to align it back into the middle of the port hole (if that makes sense)
Be delicate and use a tooth pick.

Hmmm. Doesn't appear misaligned. Wouldn't that bugger up all cables?
It fixed it for me. Dont do it if youre not confident. Just use a cable that works
I've actually just recently run into a similar issue with the kindle cable.
It sits really loose and picking it up will cause it to stop charging. But the stock usb cable works fine still.

[Q] HELP ME!!!

My Galaxy Nexus isn't charging or connecting to my computer. I've tried different USB ports, wall adapters, and USB cords and nothing. I don't really want to replace the charging port. What can I do?
Thanks in advance.

Delete this thread!
I accidentally put this in the wrong section! Thanks!
Check the charging port for Lent and stuff with a little pin or something..
That's what happened to me in the past
I cleaned it out and start to work again

Of what cujo said didn't work you have no option but to replace the port or buy an external battery charger.

In a pinch you can rig up a temporary charger using the POGO pins on the right side of the phone. Just wire the corresponding red/black wires from a cut up USB cable to the correct pins (you can find the pinouts online). The trick is getting the wires to stay on the pins - you can try packing tape. I know this is kind of a dirty solution, but it will work in an emergency until you can replace the usb port.

Can you link me to the part I need to replace! And a video of how? And how expensive is the part in question? My Galaxy Nexus isn't my main phone but I just wanted it working again.

Well, there is no guarantee that it is the USB board - but you can purchase one on ebay for under $10. The part includes a usb jack as well as a ribbon connector that connects the jack to the main board. There is, however, a chance that you have a faulty main board, in which case, replacing the USB port is not going to fix your problem but the only way to really test that is to buy the part and try it out.

That's for a Verizon Galaxy Nexus, I don't remember which one you said you had but you'll want to be sure to get the right one.

Are you using the original charger that came with the phone? It's the only thing i have luck with.

I ordered the new port! But I tried the pogo port charging and it didn't seem to work.

Won't Connect to Pc?!

I recently reset my device and did a wipe with Twrp so I could install Los with it, now currently the device has nothing on it but cannot connect to my pc for whatever reason, I tried installing drivers through Restock, and it even charges with the device powered off I have also tried other cables is there something I'm missing here? I don't know how to move forward and it used to work perfectly before the reset.
This seems to be a frequent problem with our almost eight year old N7s. There is a ribbon cable connector on the motherboard, the top board inside the tablet, which is prone to lose connectivity over time. There are inserts on the inside of the rear cover which apply pressure against two ribbon connectors on the motherboard. The ribbon cable connecting the lower, USB board to the motherboard carries charging current for the battery, USB data to and from the external USB connector, touch input from the screen and for the LTE N7, SIM card data.
Remove the rear cover, connect your N7 to your PC and see if connectivity is restored when you press on the left ribbon cable connector on the motherboard as viewed from the rear. If so, you can try adding some cardboard between this connector and the back cover to increase the pressure applied to the connector once the rear cover is reinstalled.
Good luck.
