Question about T-Mobile MDA Compact Smartphone
Attempting to operate my t-mobile MDA phone through the usb cable on my pc,phone went dead,will not light up or charge,could connecting it to pc burn the battery out,charger will not power up the battery either?
Okay, I searched and searched until I found a solution that worked for me. I tried the USB thing, I got my phone to turn on once, but never to charge. Here's what I did:
(Do this at your own risk)
I zapped my battery with a 9v battery. One wire on each terminal and then held it to the MDA battery (positive to positive, negative to negative) for about three seconds. I did this about five times. (Don't let the wires touch while they are connected to the 9v battery.) I IMMEDIATELY plugged my phone into a wall charger, NOT my computer (The computer wouldn't charge my phone). As soon as it was connected to the wall charger, I turned it on. After starting up, the orange light came on, and it started charging. I was skeptical about this solution at first, but trying everything else I resolved to do this and then if it didn't work buy a new battery, but it worked and my MDA is charging as I'm typing. The original ideal came from a post on the xda-developers website by dew1989. I added the additional steps that got my battery charging again. I hope this helps!

First of all, be aware that the MDA can NOT charge unless the OS is fully loaded. If for whatever reason your battery gets fully depleted, you have to do the following (it involves ruining a 5 $ cable and doing some surgery):
- first, go out and buy a new USB-to-mini-USB cable, unless you have 2 already (or one and the original charger)
- take out the battery
- take the USB-to-mini-USB cable, cut off the mini-USB plug and expose the four wires
- strip the red (+) and black (-) wire and twist the copper ends of each wire now CAREFULLY attach the right wire to the right connector on the battery and tape it there so it stays firmly on
- put the cable in your (running) PC or put the charger in the wall socket let the battery recharge for an hour or so, then put it back in the Wizard and reboot
- now when it is fully rebooted, you need the second cable to charge your Wizard completely, the way you're used to.
Worked for me! I've kept the ruined cable, just in case it happens again.

Once the battery dies completely. it is unable to get a charge from the phone. The phone has to be on in order for the battery to charge. This is a huge problem once the battery is completly dead.

The evident solution is to charge the battery with an universal charger

SOURCE: t-mobile mda usb port broken
The MDA aka HTC Wizard aka Cingular 8125 has a design & manufacturing defect where the internal USB connector breaks eventually. It is mounted directly to the circuit board which actually cracks and breaks. Mine broke after 13 months. Other users report this happening within a few months of purchase. T-Mobile/HTC will not fix this under warranty. Some companies have quoted hundreds of dollars to fix. Look on ebay and you will see hundreds of these offered for sale in lots with no other problem than broken USB.
CLASS ACTION SUIT ANYONE??
The USB port does not just charge the battery, this is a Windows Mobile PPC and the port is 100% essential for normal operation.
Looking for service manual/ dissasembly guide and fixing ideas.

SOURCE: Broken USB Port on T-Mobile MDA
Use a T-6 Torx driver to remove the four screws and use a fine point soldering iron. Takes about 30 minutes to do it slow and carefully.

in windows, right click on the CD player with you cd in it.
click explore and look for USB Drivers.
Install the drivers and try hooking your phone up again.
Try using a fast USB 2.0 port on the computer.
