Thanks buds but the link to the driver is stale & not sure what its called do you have a name or a good link ? Oh and do you know where the maskrom short would be ?
TY

Also does anyone know where these pins go to on the board ? The traces are gone & shining a high powered light thru the board doesnt show anything that they were connected to..

SOLVED - Ear Speaker not working

My Ear Speaker is not working anymore. Did someone have this Problem with HTC Vox 710 too. I have made a Factory reset and I have use original Firmware and other - Windows Mobile 6.5 .... Speaker don´t work but the hands-free phone system speaker is working. What can i do?
Thank you very much.

You may have to replace the earpieace. It is a separate little loudpseaker in the VOX. The handsfree speaker is on the back. If you are lucky then only the contacts between the earpiece and the PBA are dirty and need cleaning - but as these are gold-plated it is not very probable.
Disassamblnig the VOX is not for noobs - so you need to find someone that can do that.
I have repaired it . I´m a elektiker and I disassambling the VOX with a service manual guide.
I found the Vox Service manual in the Internet.

thank you for your Tip.

Congratulations
You mastered the common pitfalls then:
- SIM Door not closing properly (switch not aligned)
- Flex Cable not connected properly (the big one in your picture)
Having it disassembled, you surely did a little cleaning as well. If the earpiece was not working because of dirt, surely the rest of the device had also collected some debris.
You are fit then to replace the screen if it should ever be required.

perhaps you can get it at http://shop.ebay.com/i.html?_kw=FEMALE&_kw=htc&_ipg=100
Perfect, Thanks!!!!!!!!!!!!
I was searaching on ebay, how comes i didnt see!
hi dude,
i have this problem for my old artemis, however some things you should know...
firstly, you might find it hard to get the old female extusb off the motherboard, it has a higher grade solder so it has a higher melting point etc and wont come off with a normal soldering iron.
secondly, if you do manage to get it off, the actual pins that conect to the motherboard may be tricky to solder back on, 1 because of the grade of solder, i dont think normal solder will stick ... and 2 because the pins are so tiny.
but, lastly, i actually have one that i do not need, in perfect condition and still in the packaging!
if you have not bought one already, i will be willing to give you it, for free of course!
(because thats how i roll)
if your interested then you will need to contact me via PM dude

It could be, that your cable / dock connector is dirty or faulty.
If your could test another cable (or buy one), this would be the first step I would do.
U're right, thanks!
I have another cable, tried that and it worked!
Thanks! Never crossed my mind to check with another cable since it's the original one.
One more thing html6405 please!
Which of rom's from your page would you recommend in terms of stability and higher vers of android?
Thanks again.

GT-P3113 - Data Cable - Pinout/Wiring Diagram?

I have P3113 - Tab 7.0 Wifi/IR blaster. The cable that came with it (ebay) does not seem to support USB data connections. charges just fine. I bought another wire online (this was years ago) to no avail, still no data connection.
In comparing to the image here: https://pinoutguide.com/visual/gen/samsung_galaxy_tab.jpg (with pins being numbered 1 on the right and 30 on the left, I have pins:
3USB_DP_CON I/OUSB Data +4USB_DM_CON I/OUSB Data -
7V_BUS_1 P 8V_BUS_1 P
15Gnd P 16Gnd P
30Gnd P
Which seems like it should (?) work for data transfer with a computer. (make a lot more sense than the inverse)
I've looked around and have seen a lot of pintouts to modify things to support audio or whatever else, but does anyone know if the pinout I have is valid for USB data transfer? Is there something I can do to get the data connection working? Or do need to play some roulette with cable buying? (Any recommendations?)
I've popped the casing off the plug and it seems like wiring there should be mapped correctly, though it does look like it's cheap for sure, but there's no resistors or anything, wasn't sure if there needs to be for "standard" data usage.
Any thoughts would be great. I'm not looking to do much more as to hardware hacking right now, just getting it rooted and then more or less a simple controller.
