Re: 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??

Re: t-mobile mda usb port broken

The best solution which i had this problem happen to me was to look up a guide on how to take it apart and i held it right side up and sprayed the port with contact cleaner and let it drain rightside up the next morning it worked but only for few months now trying to find another solution to get it to work again besides charging the battery externally through a spare battery charger hope it helps

How do you charge the phone?

You can see a USB like port at the bottom center of the device. You can charge the battery by: • Connecting your device directly to an external power source. • Plugging the device sync cable into the USB port on your PC.

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)

Broken USB Port on T-Mobile MDA

My daughter's MDA had the same problem. I just opened the phone and soldered the legs on the corners back to the board. You have to bend the pins on the back of the plug down to make contact with the board, before you solder. Place plug back down and line it up with contacts. If done right should work as normal. Hope that helps

Mda not charging

Either your battery is bad or your soldered contacts on the inside to the charger port are broken.

Try charging it with the AC adapter it came with.

If that doesn't work try charging it via your computer using a USB cord

I need the data on my dead MDA!!!

Try to trickle charge it by hooking it up to the USB and then to your computer. Let it charge up a bit then try powering it on or charging it the regular way to charge it even faster.

Trickle charging
Some Palm devices have the ability to "trickle charge" from a USB port on a PC or Mac. This means that it receives a very small amount of charging from the USB port, even if it is not connected to its AC charger. If your device is capable of this function, the charging time will be significantly longer for a trickle charge (depending on the power rating of the PC USB port). However, the device may not charge at all on an unpowered USB hub (or for example off off a keyboard).
