    Who decided to make a phone that wont charge if the battery dies? This is the Dumbest thing I have EVER seen with a phone. That is like making a car that you can't fill up with gas if you ever run out. I have to say the charging trick works well. I didn't have a USB cable I could cut up, but I did have an old wall charge my dog got to. I took the 2 wires: The wires look like this (-(+)-) there is the outer case, a - wire that surrounds the + wire in the center. I touched the ends to the battery for about 10 seconds and it gave me enough power to boot up the phone so it will charge. This was a lifesaver, as I can't go a week without my phone (waiting for a new battery)

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.
Good luck!

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.

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.


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.
Any Help??

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.

No power

Make sure you have an original OEM charger for the MDA. Many of the knock off chargers don't provide the right amperage for the device. What happens is that since the phone is completely dead, it can't regulate how many amps the battery should get during the charge and an incorrect charge current won't charge the battery. I'm guessing that someone sold you a Motorola RAZR charger or another knockoff made for the RAZR. This might charge your phone when the battery is working, but not when it's DEAD. Also you won't have luck plugging it into a computer USB cable because, again, the phone can't tell the computer what charge to send and most computers only produce <0.5 amps in the USB port.

Get a charger that states it is an OEM (original eqipment manufacturer) device or one that is specifically designed for the MDA (or Cingular 8125). eBay is full of them.

Bad charger (probably won't work for a dead battery)

Good Charger (correct amperage and designated for the MDA)

If the unit is not new have you checked the status of the battery and is it a manufacturer's battery - some units are quite sensitive to that.
The problem may also be with the charger

these guys know about all of the bugs, I will go research for u.

Turn off automatic time set, there is a bug that periodically jumps zones. Also it causes active sync to run all the time.

Start>Settings>Phone then "Time Zones" Tab, Un-Check auto time set.
