T-mobile MDA Vario without USB cable - 8125, K-JAM, P4300, MDA Vario Software Upgrading

Hi,
i can how update ROM and Windows Mobile but my problem is wrong connector on my phone. I testing so many cable and OS but never sync. My friend say: You need new connector.
I don't know. I find solutions without usb cable.

goto www.accessorygeeks.com and order the ORIGINAL HTC USB to mini USB DATA SYNC cable....
the problem is that there are mini usb cables out there but they only charge not transfer data... they look exactly the same... but the data transfer cable has one more wire inside for transerring data so it can work with ur ACTIVE SYNC...
It happened to me for over a year til someone told me...sheesh..now I was able to update my MDA and even root it
Good luck

I have successfully been using a USB cable that came with an external hard drive.
Never had a problem using it for data, reflashing, etc.

How to unlock when my USB port broken?

My phone is cingular 8125, my USB port can't sync with PC, I don't know what is going on. When I plug the cable to PC, it tell me unknow device detected. I can't do anything thur USB. Can I unlock by SD card or IR port?
Have you tried connecting you phone to a different PC? Also deinstall Activesync and reinstall it (are you running 4.2 or 4.5).
are you able to charge your phone with the AC/DC charger? if so ur port isnt broken.. so try doing what mmrfrazzz says and u could also go a step further and try uninstalling the usb port drivers then reinstalling them. do your other usb devices work? does ur phone indicate its charging when plugged into usb?
I have 2 8125, the other one is OK. I am using Activesync 4.2. I replaced the USB port, it's work for minutes. After dinner, it only charging but not sync!

From what I understand from your post, it sounds like you have a cold solder joint on the contact or contacts that carry the sync signal; you may need to re-solder these. It only worked for a few minutes because when you applied pressure to the USB port by inserting the plug you compromised the already weak solder point. It works when charging because it charges over different contacts then when it synchronizes. It seems your first solder job was not sound.
PS. If the solder is dull (not shiny), it usually indicates a cold solder joint.
I had this problem with an 8125 i bought on friday for 20 bucks. they had broken the usb port. so i took one out of a razr phone and put on the 8125. at first it would only charge thru usb but not hook up on activesync. but then some how when i soldered it it worked and was able to update it and all that crap. The only thing is that it will not charge with a regular charger. it will only charge when connected to a computer. but hey atleast it works now.
Yes, I was re-soldered the USB port. I have compared my workable and the un-workable one by electric-meter. They are same connecting status, but just not work! I can be charge but not synchronize . Is some IC or chips damaged?

which program do you use to over clock your 8125? can you post here or send to me? [email protected]
I use batterystatus. but the thing is is that some devices respond different to speeds. for example my MDA can only be overclocked to 286. anything higher it freezes up. On my 8125 i can overclock it to 299 with no problem at all. So its trial and error. try it out and see what you can get.

sync cable

Just bought a Kaiser and there was no sync cable, can I use any old mini USB to USB to flash HardSPL, unlock etc?
yes you can
Thank you amigo!
There are cheaper cables which will only charge the unit and not create a data connection to your pc.
I tried 3 of these cheaper cables until I got fed up and got a quality cable.
So just in case this happens to you... if you got a problem its 99% most likely to be poor cable.
I used my cable and it was fine, flashed HardSPL, and a cooked ROM, I'm getting an original cable anyway just to have it

[Q] USB connector problem

i have diamond from altell,....i can charging with my cable usb, but i cannot use it for upgrade ROM,....i know this is usb connector problem because i cant even syncronise my diamond with my pc with activesync.
is there any way to upgrade rom/unlock this diamond without usb cable ??? pls help me
If you are trying to install a custom ROM you are out of luck as the SPL unlocker requires a custom SPL afaik. If you are trying to update an official ROM you can just get the .nbh file and rename it as DIAMIMG.NBH in the root of your SD card and hold Vol down and Back key (I think) while turning the phone on until you see the tricolor recovery screen.
One thing to check is to use a different cable. Some cables are charge only and do not carry data signal, or the one you have is bad. Check device manager to see if the PC sees the device at all.

Is there any chance you used a dock charger with your phone? Mine did the same thing you described (checked cables/USB ports/computers and it is indeed the USB port on the phone), and the only thing I can figure is I used a USB dock for a while with my phone. The phone would connect via USB without any trouble before using the dock, but sometime after using it, I noticed the USB stopped working.
Just curious...

Yes downloaded the correct Samsung drivers....have ADB installed
Not using original cable but it works to charge through the PC so why would it not be recognized as a device?

Power and data pins are different. The cable may charge your device, but it doesn't guarantee data transfer to work. Many cables use MicroUSB connectors, but no all cables have all pins connected. I have an LG charger that works with no issues on LG phone but can't charge Captivate. In the same time Blackberry charger and USB cable both work fine with Captivate. I have also a generic USB cable that can charge Captivate but doesn't provide data transfer. Original Samsung cable works for charging and data as expected. I think you should try with another USB cable.

[Q] D959 Drops USB Connection to PC

When I first got my G Flex I didn't have this issue. Now it has slowly progessed to the point that it's dropping the connection every 30 seconds. This is a brand new Windows 8.1 PC and it's connected to the USB 3.0 port. (I've also tried the standard ports) I've found a hub that's externally powered. Could that help? Can I do a factory reset and keep my root? TIA
Sounds like a bad USB cable.
Try it with another PC /different cable
Worst case it's a broken USB port on the PC or phone.
Have you tried cleaning the USB port on the phone/PC?
