problem with syncronization

hi guys i'm enjoing my great touch jade, but i encountered an annoing problem in syncronization: i can easily install activesync (i'm on xp pro sp3 and i've got office pro 2003) but when i connect my jade to pc nothing happen.. i mean, the phone start charging, but no sync go and windows send me a message about unidentified device, i haven't driver... how can i manage this situation? i'm trying since 4 days.. 've tryed softreset, searched everywhere and it seems that i need driver for a net-adapter NDIS.. i tought an activesync corrupted files, i downloaded from microsoft.com, but didn't work anyway. is activesync that don't install driver or my jade that got something wrong? i also tryed to change the usb cable.. isn't my cable..
nothing works...
sry for my unperfect english, i'm managing learning!

Have you tried unchecking start>settings>connections>usb to pc?

Two things you can check:
1. Check on a different comp if you can. I suspect a problem with the usb port on your computer. If you can, try plugging it into another usb port and trying that again.
2. Check the connector pins on your jade. Sometimes they get bent the wrong way and that causes the device to not be recognized when connected.

You should be able to see the pins using your naked eye as well. Their in the mini usb/charging port on your phone.
Would you be able to check this using another WM phone? Does any other device work on your comp? Mp3 players, camera devices etc? Are those detected?

When you plug in the device and windows asks you for drivers, check "install from a list or specific location" and in the following dialog point "include this location in the search" to "C:\Program Files\Microsoft ActiveSync\Drivers" if your system is an english one...for other lang adjust accordingly. this should install all necessary drivers and render it working...

Hm, this worked for me. Try going to the device manager and uninstall the active driver, then re-try the above.

now i'm at work, but i tried yet this operation, and it tell me that no driver is installed for this device.... -.-
the real problem is that when i install activesync, he don't update the system with the right driver for my jade... i tryed on my girlfriend pc, she's got xp home and its the same... at now i can't try on vista, because the only one i know who use vista is on holiday... but i wanna find that shi##ing problem and solve it...

ActiveSync works fine with my WinXP SP 3.
When i connected Jade the first time XP asked for a driver. I ignored this.
Then I installed ActiveSync from one of the CDs that come with Jade.
Of course, you will also have to select ActiveSync (not "drive") on your jade when you connect it to the PC.

i writed in microsoft forum and sended a mail to htc to have fixed drivers.. i'll let you know if i manage..

update:
at now i can't manage to sync...
tried hard reset, asked microsoft for help, and htc too, they said i can have a hardware problem on my touch, cause nor in my friend laptop with vista can get drivers.. from htc they told me they can replace my touch with a new one...
i think i'll get this way...

Activesync: Unknown device

Hi all,
It's been a while, but I am back with HD2. I have a problem. I have win7 business on all off my computers, I instaled latest activesync, but I keep getting error connection. When installing drivers, I get the unknown device, so instalation failed.
Not even bluetooth recognition works.
Any suggestions, please?

If you are using Windows 7 Business, I would guess you mean you are using Windows Mobile Device Center, yes? In Windows Device Manager are you set up to automatically download drivers? Are you getting any errors in the Sync Center? There is a lot of information you have to supply before anyone can troubleshoot the problem you are having.
There are a lot of steps you can take, most of which you can find by doing a search of XDA. If that fails, then come back with a more detailed explanation of what you have done, and people will try to help troubleshoot for you.

Thanks for looking,
and yes I have been searching a lot for information allready before I made a new thread.
I have win7 business and yes it does download drivers automaticly.
I will try and search for manual driver setup, but would be very thankful if any of you could give me some hints.

In Device Manager you can click on Portable Devices and see if you see your HD2 there, if you do, then right click on it. You can find options to manually install drivers. If that does not work, in the Mobile Device Center you can configure how the center is supposed to connect to your HD2. Have you tried that yet? Also, make sure you are not using a USB hub for connections. You can try changing USB ports to try to reinstall drivers.

I am trying hard, this is the error I get:
P.S.: in activesync all options are on, so no problems there, but I have tried all of them.

In that case, try uninstalling the device in Device Manager, and starting over again. It does seem to be a driver problem. Another trick you can try is on the HD2, under Settings, USB to PC, try unticking Enable advanced network functionality, and then try to reinstall the drivers.
Another thing you can try is deleting the partnership in Windows Mobile Device Center and creating a new partnership.

Is there a wa I could find the driver somewhere and install it myself?

In the Leo ROM forum the thread on MTTY has some Windows 7 drivers you can download I believe, but that will take awhile.
Are you using Win7 32 or 64 bit?

win7 32 bit. I tried to download them through windows update, but I got an error as well.
So I am on a quest for drivers....

If you are familiar with computers, you can try this with Win7 drivers you download for HD2.
You did try uninstalling your device in Device Manager, and trying another USB port to install it on? It seems really odd that Win7 is not finding the right drivers for you, and that persists even after you uninstall and reinstall the device.

No luck so far, any more ideas?

Update:
I tried the same thing on another laptop, same specs, same win7 business, worked like a charm.
So must be this win7 problem I think. Any ideas what to do? I can't remove mobile device center, so I could try and reinstall it. The icons stay in my control panel.

Anybody?
I just can't imagine this is only happening to me.

Did you have any luck yet in solving the problem?

Nope my dear helper,
I found out this is windows7 problem. I still get the first error can't install device driver, because the device is not installed on the computer.
Something must be wrong, but I was getting a head, network driver installed fine, windows mobile device program runs fine, I made a clean install with register delete etc...
I just can' seem to find this to work.

i had some problem the first time i plugged my HD2 on win7 64 ultim.
nothing happened, no activesync, no nothing...
i opened sync center, nothing...
windows updates found me windows mobile device center with upgrade devices, the thing installed but all still worked bad, impossible to activesync, no driver for my HD2, and i know nothing about phones and windows, it's my first windows mobile.
so after hours of fighting, i decided to DL the app windows mobile device center on microsoft download website, then i installed the thing and oh miracle, my HD2 was detected, the app Win M D Center was asking me now with the pic of my hd2 in the prog to chose between settings as the first thing installed by windows update always froze at win mob device center splash screen...
i resume here but it took me the all afternoon to finally resolve this problem.
something went wrong with windows update install and to reinstall the all app was the easy way to fix the activesync problem.

If you did already re-download Windows Mobile Device Center and that did not work on the one recalcitrant computer, maybe you might need to update your BIOS or download the latest drivers for you motherboard. Sometimes problems can crop up if the computer does not have the most updated BIOS and motherboard drivers. How old is the computer you are using?

Well, after calling microsoft support and HTC support and doing for 36 hours nothing but trying I finally reinstalled my hole system. So new clean install of windows 7 business and it works like acharm. Where did it went wrong, I don't know, there had to be some register issue I think. Windows mobile center worked ok, the connection with the phone worked, but just not recognizing the device. Well I would of done the instalation sooner, If I knew this one is gonna be so hard to do.

Well, glad you finally solved your problem, and that this time the blame was not just placed on HTC or the Leo. Sad though that you had to go through so much to get the darn thing to work. I just installed a new operating system for my neighbor, and there is still more work to do on it. Not a fun thing to do.

HTC HD2 Drivers won't install Win 7 x64

Anyway to manually get the drivers for it? I can't find them and I can't sync my device to my computer. Windows Mobile Device Center won't work at all, it doesn't recognize my HD2 and it says the driver installation fails.
Can someone help me out please? Thanks

Windows Mobile Device Centre was all I never needed on my win7 x64. I installed the program before inserting the HD2 though. Obviously make sure you have the program up and running before plugging in the HD2 and selecting activesync on it; It should load up. You could uninstall the driver (from device manager) and start again if all else fails.

What if it does not?
Started doing that "cant recognize" issue while installing NAND (at the radio installation process -r: 2.15., compatible)
Figured to go to stock WinMo with SDCard, but it still cant..
Faster data sync disabled, after that it tried to install the drivers again, but says it fails...

Gotta go to ms and install the updated win mob dev c. The one that ships needs updating.
Also, once you are into the android side of things you should open wmdc, connection settings, and turn off allow usb connections, and install the android usb drivers.

Thanks mate, but done everything, I mean everything. Now I'm totally stock, original SPL and original WWE ROM, everythings working like a charm, besides connecting to a PC. Also tried with another computer (XP) and another cable. I can say I've done everything I found on the net, but nothing helps. Uninstalling driver, uninstalling HTC Sync etc etc etc... It just cant recognize the USB..

I have been using it win 7 64 bit since the beginning. and I never have a problem with the driver.
Try redownload and reinstall Windows Mobile Device Center from Microsoft website.
Only connect your device after the driver has been properly installed.

in device manager delete usb controller after software installation.

Thanks to ALL, but changing the USB cable, so sure that's ALL? =)
I'm not gonna mention that I've written that I've tried it with many computers and many cables. =)
The phone is sent to HTC and they told me that they ordered a new mainboard.
Hope doesn't take too much time. My Service Provider gave me a Galaxy 7500.. Cupcake, no market.. arrrgh!
Thinking of buying an iPhone and selling it after two weeks but that's gonna cost me $200 loss in two weeks. too much =)
As doing some thinking.. the device cannot "introduce" itself to the computer. I couldn't find a more sense making answer.
If you've tried hard-resetting, cable and PC changing, if it's still not working, then there should be a problem about the phone, mostly about the mainboard.
I suggest anyone having that problem go make your phone check at a service, of course if you have warranty. =)

CDMA WS / QPST Not Detecting Phone

I have read a few threads where people claimed to have made a connection with Sony Ericsson Xperia Play via CDMA Workshop and QPST. I have visited the official site from Sony and downloaded the drivers. Still no luck picking up the device on QPST or CDMA. I have installed Gordan's Gate's drivers and still no luck. Can someone point me in the right direction to getting the play detected? I have the R800X version already unlocked and rooted...
Note: I can successfully flash my device to CM7, and the other custom stuff. Thank so much to Ash, Mills, Doom and everyone else with so much helpful information....

simple buddy all you gotta do is open your phone dialer like if your gonna make a call and hit ##3424 and ht call itll take u back to your home screen its normal if it does attempt a call u did it wrong
after that if your using win 7 itll auto download the drivers this is to make a DIAG port if using diff os not sure look for the drivers on google
after that go into your device manager on your computer and look for what port number it gave you and go back to cdma and connect read and write spc is 000000 no extra steps are needed for the spc code
ps try to do it running stock rom because some users remove DIAG on customs roms why alot of people have trouble

Oh no! I have to install windows 7 because I am currently on windows XP (don't tell nobody!). I have been to the sony site and downloaded the PC companion and all 4 driver sets hoping it would be enough to get QPST to recognize my device. Still nothing, I can however connect with fastboot, flashtool, adb, but no luck with QPST detecting the phone no matter what I do.
If anyone out there have XP drivers for QPST that will detect the Xperia Play please share!

try these out make sure you got usb debugging on and hit ##3424 and hit the call button itll take you back to the home screen and when it tells you to locate drivers unzip my rar file and put them like on the desktop or something and try it out
qpst has nothing to do with it for the most prt you need drivers for the DIAG diagnostics mode only then will qpst will detect the phone

Okay it looks as if you both are right lol. I just realize my laptop don't have a Com Port and that may make a difference. I will install the drivers and ADB on my desktop tomorrow. Since I am running CM7 I will use the shell command to get to the enable file.
Thanks for the pictures! I noticed that I had the same stuff you had Edo except the Com port device. Oh and in stock I was able to do the 3424 code, but in CM7 it made a phone call lol.
Thanks Blag when I did the echo enable command on my laptop it booted me out of adb but I didn't have a com port lol.
Thank you guys for so much help!

You know, guess I'll have to quit it.
My phone's USB PID is E15D and it's not listed anywhere in inf files and I can't even start instalation via device manager. When I manually edit PID in inf to E15D, instalation fails with message install class is not present or valid.
EDIT: OK, after more editing I successfully installed it, but QPST still can't detect it (it's GSM R800i).
EDIT 2: Got it working in the end thanks for your drivers

huh those werent pulled from my computer they were downloaded from website thats how i was able to install the drivers there not attached to my phone in any way

I am the only unlucky person in the world! I think it is because I am still on windows XP. I will no longer put off installing Windows 7. Them drivers are not working for me at all. I just get the sony ericsson device with adb drivers showing up in my device manager. The other devices there are SEC HUSUB and they always have that problem symbol, the one with the yellow question mark. I try to install the drivers from their location and I get the message they don't have any information pertaining to the hardware.
Thanks though!

you have to manually edit inf files.

PC cant recognize
I have been struggling with this issue as well.
Simple solution i found (and after reading about million posts on web as well)... ORIGINAL CABLE seems to solve the issue. I saw it posted even on one Korean forum. Seems simple enough, use original data cable that came with phone and that seems to be it. wierd

Totally agreeing with PP
PP is correct in suggesting the original data cable being used.
I had the same issue, the pc would not recognize the phone. The fix for me was to connect to the usb ports on the back of my pc. They were the only ones that let the phone connect to zune.

Btw, for these issues with USB only working on the back of the comp the culprit is either the motherboard (drivers or other) or the PSU (not enough power).

Enderpsp could be right.... Mine was the USB port, I had to plug it in a different port and it started working... Just keep trying, make sure you don't have any USB options about power management in your computer's bios
