does it sync over BT?
i had the same problem before & i still do, but soem other guy here in the forum said it worked for him when he uninstalled AS then reinstalled it again.
try it, it might work with you.
until now i'm still stuck with BT syncing, i cannot sync over USB.
i still get "connecting" message all the time with no progress.
Hi Guys
I had EXACTLY the same problem, alhough I could not get BT to work but could get IRDA to work.
Here is what I THINK the problem is, by the way i-mate were useless it was a colleague at work that had finally found this problem on his device.
WM5 devices when connecting via USB create a NETWORK. Strange but true.
SO, open Control panels, open Network Connections.
Attach your K-JAM (or other WM5 device) you SHOULD see a new network get created with a random number at the end of it (the number changes depending on the USB port you use so you MAY need to do this procedure again if you connect via a different USB port).
Get the properties of this new network when it opens you should see that NONE of the services are checked.
Check them all.
Close.
Everything SHOULD suddently spring into action, it certainly did for me.
It appears that some PC config's (all our work ones) need to be configured this way were as otheres set themselves up fine.
Let me know if this works.
Cheers.
Robin
the wierest thing just happened.
i wanted to try your solution, i opened the network connections folder, connected my kjam, and for my surprise it just connected without me doing anything, and i had it sycronised over the USB.
BUT, the wierd thing, is even though i have the connection, and it is syncronizing with my laptop, i don't have the connection icon on my kjam, instead i had this message (attached).
what does this mean?
Don't know, I have never seen this!!!!
Robin
the strange things keeps coming...
when i wanted to sync my device again this evening, my whole laptop freezes without any responce.
can someone here tell me what's the problem i'm having here? & how to solve it?
i don't wonna format my PC over this.
thanks all in advance.
I have noticed that the synchronisation only happens properly if I connect to the SAME usb port. If I connect to another port, the laptop picks up the connection but won't synchronise.
Connect to the same USB port and voila!!
Hope that helps.
See my reply earlier.
Each different USB port you connect too AS creates a NEW network with a different number on the end of it.
You have to open the network properties for all the networks (with numbers) you intend suing and make sure all the properties are checked.
I use 3 different USB ports on my laptop depending on wether it is docked at home the office or undocked.
I have had to do this procedure for each port but now they ALL work smoothly every time.
Regards.
Robin
i did connect it to the same USB port, but no luck there, the same problem. i uninstalled the AS twice and re-installed it but it's the same.
hi.
i have tried yr solution by ticking all the boxes in the 'new' network properties. won't work though. the sync. icon shows 'connecting'.

Strange.
I know a number of people this worked for.
You could/should also try disabling your firewall and giving it another go.

connect over USB killing EVDO

Hey -
Sorry if this has been covered before but it's so hard to find what you're lookign for with search sometimes.... anyways...
I got a nice lil cradle thing for my xv6800 and want to have it hooked up to my laptop when I'm in the office. I seem to be having a problem though when the device is connected it kills all regular VZW connections over EVDO... I have the device in sync with exchange server 24/7 so need to make sure it keeps the connection to VZW even while connected to the PC. It seems PC connection is trying to override VZW for some reason?
I went through the connections settings and removed all but Verizon Wireless in there but USB still doing some kind of an override....
am I missing something? Anyone have any helpful hints to allow my device to stay connected through EVDO while docked to PC?
Thanks
still cant find anything on this... activesync over bluetooth doesn't affect data connection but USB kills it.... no one has a solution?
oh come on.. all the ppc geeks in here and no one has any clue?
maybe I posted in the wrong forum for attention?

help with JasJar

hey guys as per directed with few good helpers now i successfully got my JJ back.. but my pc both Xp and Vista dont find it connected.. my device shows orange light ie of charging but when i try to do anything on it (eve press a light button) the light goes off is there any problem???!!! as the device manager wont show any devices connected even as unknown device!!!
pls help ya buddies!!!
http://forum.xda-developers.com/showthread.php?t=280340&highlight=Active+sync
Hope this helps, if not have a deep read to the Wiki
thnx dude bt the problem is
the active sync doesnt work so i have no either ways on how to paste that file to my JJ and maybe hard reset of my phone solve the problem?
Yes, most likely a hard reset will solve the problem
If hard reset didn't solve it, make sure you are running the AS 4.5 (can be downloaded for free from MS). Try another USB cable, or another WORKING USB port on your computer to exclude other possible culprits. If still no signs of connection - I suspect your Uni USB port might be faulty. It is attached, seeing it allows you to charge, but sometimes one of the signs of trouble is failure to sync.
well... just two days back i did DOC FORMAT from the same system... @ Vista and after that whenever i connect the vista sound of connect and disconnect of any hardware plays... ie wheres the problem i cannot get.. .and as i said... it shows charging but when i click (or press) any button on my JJ the charger sign goes off (d orange light) at present also its showing chargin on my phone.... and to get me more worried... now the mtty is aint working too
tried all the things as per said in th wiki (for DOC Format) but the usb aint showing up both in XP and Vista!!!!!!!!
and one more thing i noticed.... after hard reset my JJ would show the network bar and all that the sim is inserted but after that if i soft reset my phone... it says insert sim... i have this 2005 rom from clubimate.com
the rom problem or the radio problem or my sim problem... as i have tried few hard resets.// i can conclude that rom has some fault.... maybe
i dont think i can get my JJ back to normal

Won't connect to 3G when docked!

Hi all.
I have the problem that when I have the HD docked either in my carcharger or regular charger it won't go online on 3G network.
I think there might be a setting saying it should use USB connection instead of 3G when available, but cannot find it.
Can any of you recollect where to find it?
Right click the active sync icon in your system tray and open up "connection settings..."
On that dialog, make sure that "Allow wireless connection on device when connected to the desktop" is ticked, and that it says "This computer is connected to" "Work Network". (That last setting tells it not to use the USB connection as an internet connection.)
I used to have the same issue and those steps fixed it. Hope you have the same result mate.
Actually, I've just reread your question and noticed that it doesn't work when plugged into the charger, not just a PC.
I'm afraid that advice won't help at all, and I've never had a problem with this unless connected to a PC.
Good luck with it!
Is there any chance that you have an automatic profile selector?
I use SPB Phone Suit and have the phone off when I'm charging at night.
Thanks for you comments.
I will try a hard reset and see if I somehow can change something in the setting up.
If I find an answer I will post it here.
Thanks.

USB Sync

I have searched this forum, found some Sync issues but nothing that relates directly to my issue. If I just didn't see it, point me in the right direction please!
I have a TILT2, stock ROM, I have made some reg mods for text msg notification, Data speeds & auto rotate via G-Sensor. My phone was syncing perfectly fine for a few weeks and I have the USB to PC "Enable Faster data sync" unchecked.
I lost sync a few days ago, I rebooted phone & computer figuring that would fix it as it has in the past only to find I only get charge light, no data connection. I don't hear the bum-bum audio indication that it is connected, and the device does not show under Device Manager nor mobile device manager and my connection methods include USB & Bluetooth.
Here is the caveat, I can sync to the computer through my bluetooth on my PC and I do hear the audio tone connection. I figure a reg change affected this, but I reviewed my changes, nothing dealing with USB, and I even reverted back to a Reg backup from prior to the problem occuring - no luck. I have swapped USB cords, nothing has helped.
Does anyone know of registry setting that would disable my USB sync? Do I have a defunct device?
Assistance appreciated - Dan

Is this of any help to you?
http://modernnomads.info/wiki/index.php?page=Windows+Mobile+Device+Center+Troubleshooting
Thanks for the link - I had found this before, and it really deals with no connection at all. I ran through most of the post, nothing helped. Considering I have sync via Bluetooth, it is not firewall.
Looking at restoring my computer to sometime last week, see if an update that came through caused this.
I'll post more when I done the restore.
OK - Update. I restored my PC to prior to issue, no luck. I disabled my security suite, no luck. I have tested the phone on another PC, it acts the same. communicates via bluetooth, but only charges via USB.
I am starting to work my way through the phone registry, is there any specific setting I should be looking for?
I'm just going to throw in a suggestion here: have you tried using a different cable? Often times the cable is the bad piece of the connection, but people don't even think to switch it out with another one.
And as well as the cable, have you tried a hard reset on your phone?
same problem!
i have the same problem. went to htc and they told me sorry you have a 3rd party rom so we are not going to help you.
yes i have treid 4 other pc's and 3 difrent cables and no luck.
please help!!!!!

I had the USB port go out on my TP2. I used the SD card to flash the sock hard SPL and then used the SD card to flash the stock T-Mobile ROM. Then I sent it in for warranty exchange. I suggest that you do this and then seek help from HTC.
cool can you perhaps help wit how to do it? please?

same problem here and the problem that the battery was draining even when the phone was off. call htc and the next morning the ups was at mine house to get the phone. 7 days later the phone was back with new motherboard. a had started a tread in general of this problem
Yep, mine too. I had to send it back to HTC UK for repair after the USB socket stopped working - came back with a new mainboard.
It looks as if it's prone to failure as I'm careful with connecting and disconnecting cables and it looks as if this one is already starting to go again!
Can't fail HTC UK Repair for it's great service though...
