Re: MDA (i really need this phone to work, my fav. phone)

The battery has been depleted beyond the level that the charger can handle. As someone else alluded to, if you are using a Motorola RAZR charger or a USB cable from your computer, it won't work to charge the phone. You'll need an OEM charger, which will provide the correct amount of amps to the battery without the charge having to be helped by the phone/computer.

Mine did this after I kept trying to start it when the battery was dead (yeah, I thought it was a good battery). I bought a new battery AND a new charger because it came to $12 total after shipping. Both worked perfectly to get me back going.

New batteries are like $7 on eBay and new chargers are about the same, so take your pick.

Your battery has been depleted past a chargable state. You can fix this, but do so at your own risk. You can simply purchase a new battery, that will work, just been sure not to let it deplete the battery totally anymore. Now, on to the fix -Take out the battery. -Get any usb cable you can find sitting around. (any usb wire will do, an old printer cable, anything with a usb end that can plug into your computer) -cut one end of the plug off. You need to leave the side on that connects to your computer. Cut off the side that plugs into a device (printer, camera, web cam, etc) -Strip the rubber off the wire and expose the wires inside. -Separate the wires from each other. You will only be using the BLACK and RED wires. -strip the very end of the black and red wires carefully using a wire cutter exposing the metal wire inside the red and black covering. -Plug in your home made battery charger to your computer. Careful not to touch any exposed metal, as it will give you a small shock. ****WARNING**** DO NOT UNDER ANY CIRCUMSTANCES ALLOW THE RED AND BLACK WIRE TO TOUCH EACH OTHER ****WARNING**** -now carefully hold the black wire to the negative terminal on the battery (it should be noted with a black circle with a - in the middle). Then touch the red wire to the positive terminal (it will be noted with a red circle with a + in the middle). Hold the 2 wires there for 20 seconds. Then quickly plug the battery back into the phone, and then plug it into a regular charger. Give it little bit of time, if you've done everything correctly the charge light should come on. I had to repeat the last step again to get the light to turn on indicating it was charging. You must not hold the wires to the battery for too long, 20 seconds should do it. You can overload a battery with this trick and actually make it explode if you hold it there too long. You are well within the few minutes needed to detonate the battery due to overcharging by sticking very strictly to 20 seconds. Just be careful and you'll be fine. One you get a charge light give it a few minutes in the off position, then try powering up the device and keep it plugged in until you get 100% charge. Good luck, Peter 561-537-3208

The freezer thing was a stupid idea. Maybe your charger is not an original charger? or if it is the charger port could be loose.

My T-Mobile MDA won't turn on or take a charge, battery was low

I had the same problem, but got the idea to "jump start" the battery from Googling the problem. At night, I had turned off my MDA to charge the battery and then in the morning, couldn't revive it. I removed the battery from my MDA, and determined which battery terminal was positive (far end of one side) and negative (far end of the other side) by using a multi-meter. BTW: Battery was still @ 3.5V (okay…battery was still alive, if just barely). Then, I found a 5V DC charger (5W Max output = ~1A) from my bluetooth headset. I used one wire (CAT5E) and connected it to the negative side of the adapter (outer sleeve - again, verified by multi-meter) and another wire to connect to the positive tip of the adapter. I had to strip about 1/2-inch of the insulation off of the wire on the DC adapter side, and about 1/8-inch of the wire on the battery side. Plugged in the 5V DC charger and then I touched the negative wire to the negative battery terminal and held it there, while I touched the positive wire to the positive battery terminal for about 30-45 seconds. Put the battery back in the MDA, started it up, and now it's charging on the regular MDA AC Charger that came with the phone. Problem solved.

Hi my name is Jimmy, I have a Tmobile Dash. I have just installed mobile 6.1 and it is cool but I have two problems with it. First it dose NOT have myfav on my phone I...

My Favs can still be used even though you can not see the my favs icons on your front screen, you can still call those people as they are still listed with t-mobile and it will not cost you, Also you could put them on speed dial and you can still add pictures to those people in your contacts so you can see there face when they call you, I had a T-MOBILE MDA and it works the simular, Any way with the L instead of the @ symbol could be a language settings problem or it could be the button on your phone goofing up. Good Luck with that.

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)

Battery won t charge or operate phone Problem - T-Mobile MDA Compact Smartphone

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!
