USB Sync Problem

[Synablade]

Hi all,
my TMO-MDAIIIc stopped syncing over usb cable!
I do not have any clue why!
Last thing i remember i installed the OpenVPN-Client!
I did this before on Windows Mobile 5 without problem.. So i presume it's not caused by OpenVPN!

Nevertheless i wonder if anyone has experienced this as well? I tried to connect the device to several computers without even ActiveSync recognizing it. But loading the battery over USB still works!

I also do not get a "Network Interface" if i connect the cable.

I searched several forums and find out there were similar problems, but unfortunately no solution for me...

It seems not to have something to do with the "Notification deleted" problem..
As i can see several replog.exe notifications. Also the one about RS232 Connections... Is there any other Notification missing maybe?

I also tried to play with the USB-to PC option in the settings menu. No effect.

Im totaly clueless i can sync via bluetooth, and irda, and of course wireless (gprs).

Any help would be much appreciated!

Cheers!
Syn

My phone stopped working the same as yours about 6 months ago. I recently found out that it was because i charge my phone in my car, which can damage the USB Interface Board in the phone. (usually when you have the phone on charge, and then start the car, causes a spike in the current).

As far as i know, the only way to fix it is to send the phone back to the supplier, who will replace the board under warrenty.

Assuming you have the same problem :)

Hi, thanks for reply!

could be true! I also charge it in the car frequently... I didn't payd a lot attention to if i plug it beofre starting the car or after...
So my last try now seems to be a "hard-reset".

I'll let you know if it fixes the problem.... If not....
I may need to "downgrade" the phone b4 sending it right?

Cheers!

yeh, its probably a good idea to put the original ROM back on :p

[Synablade]

What's really bugging me is:
Why is it still "loading" the battery after damage to the USB-Circuit??

Anyway.. i did the hardreset, and guess what...

no effect... my problem now is.. if usb stopped working.. how do i flash back to original rom? :->

bluetooth? *shudder*

Cheers!

yeh, same as me :) i havent been able to flash a cooked ROM to mine at all. You can change the ROM by using the MicroSD, as long as you are USPL unlocked. There is a section in the Wiki about how to do it.

You cant change the ROM using bluetooth, caus half way thru flashing, whats gonna control the bluetooth??! :D

The Battery still charges caus the battery charging circuit is seperate to the USB control circuit :)

Are you guys running XP on your comp/laptop? have you turned off your firewalls? i had problems syncing on my laptop with xp, now i use my comp, but i found if i removed firewalls all was ok. if you have tried reflashing, or if you havent flashed any new software if you have tried re-sinstalling active sync, try the above, im sure its somethign simple

I've tried everything... WinXP, WinXPx64, Win2000, Win Vista, active sync V.3-4.5... :confused: the only answer is to send the phone back to T-Mobile, they will fix it under warrenty tho, so it aint so bad.

hi thank you all for your replies!

unfortunately i think mugglesquop is right,
the device died from power overflow from car adapter...
funny thing here is: i use a motorola car adapter all the time! no problems.. then i changed to a tmobile provided adapter! And now it seems that tis one is vulnerable to power highs! Great!
You know what ? I love t-mobile for providing "cheap" "crappy" hardware!

actually im downloading the original rom i found and i will try to flash it back via sdcard. Then i will send it in!

Cheers!

What rom are you using ?
I had the same problem & i was using B&B4.3. It took me a couple of days of trying before i could get an activesync connection. I then flashed O2's mobile 6 Rom & hey presto everythings working again (now trying different rom). Not sure it was the Rom as only a few people seem to have experienced the problem. So it could have just been a coincidence. Also i would assume that the problem should be instant rather than after a few days of having the rom flashed. Have you tryed jiggling the usb cable about in the phone to try & get a connection ?
