T-Moblie MDA Dead

I bought a MDA off e-bay and it worked great for 3 months. Then, without warning, it just stopped working. I had it plugged in over night, battery wasn't depleated. Thinking the connection was bad I pushed pulled and wiggled until I broke the charging port off. I had it repaired, bought a new battery. Everything was fine for 3 days. Same problem. Plugged it in at night when it still had 80% full on the battery. Tried to turn it on in the morning and nothing. Completely dead! Any help will be appreciated.

Re: T-Moblie MDA Dead

MDA's are BAD BAD BAD.  I'm now on my third phone for the exact same reason.  It just wouldn't turn on, charged or not.  I sent it back, stayed without a phone while they UPS it (because they don't manufacture the phone any more, so they send refurbished phones).  I am so sorry I switched from Verizon to T-mobile for this phone, I could scream.  They replace the phone with either another piece of junk MDA or the "Dash", which isn't at all close to the style of keyboard I bought the MDA for.


It's worth it to me to pay the $200 early termination fee to not have to pay $80/month for a phone, which really isn't a good phone at all, anyway.


Good luck, but it will do you no good with T-Mobile.  Sorry to be so negative, but after spending $400 for a phone and to have to replace it twice in 11 months, I have nothing positive to say.

Re: T-Moblie MDA Dead

I did the same thing, Blue Bay Electronics had a seven day warranty just long enough to fool me into giving a good report. Anyway look for a repair center and spend another 100.00. Good luck

I cant get my mda to turn on i hold down the power button for a while but it wont turn on i charged it for 3 days and it still wont work what should i do?

Mda Vario's don't charge when turned off, heres what you do.
cut wire off a usb lead the small end strip the red and black wires, put the red wire onto the posative connection where the battery is it tells you what side is posative and negative on the battery, use black with negative and red with posative making sure that no wires touch the other metal strips in the phone, replace battery plug usb into computer and start up the mda and wait for it to boot. once turned on leave to charge as it will charge through the wires connected to the battery, after 10 to 15 minutes plug in the actuall charger and try to remove usb wires without taking battery out. if that is not possable it is ok as the battery should have enough power to start up once it starts leave to charge and always keep some charge in the phone.

MDA Vario died - HELP

hi. i have had the same problem and have had to change the battery twice in the three years i have had it. sometimes the batteries that you can buy off ebay are quite cheap but go off without any warning fairly quickly.last one i have bougt has lasted me 1.5 years without any probs.
my other advice would be to back up your contacts/other sensitive information somewhere safe( your phone SIM for example- which has to be done one at a time for the mda vario)as well just in case.
hope it helps

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)

MDA will not power up.

another this to try is get a new battery.
mine had the same problem i would try to charge and nothing and it would turn on for about 30 seconds then turn off and i tried putting it on a charger within those 30 seconds but it wouldnt take a charge.
i got a new battery theat had some charge in it and it worked great! alot of the time thats all you need it a new battery

MDA 3 dead

If a device fails during a rom upgrade its as good as dead because it doesn't have enough instruction to start the process over.
