The Windows Mobile installation may be corrupted.
The only way to fix that problem is by re-installing the windows software on the phone.
You can get the software for the T-mobile dash at the following link: http://www.t-mobile.com/wmupgrade/
Be warned that if you use this method most of the data on the phone will be lost, like text messages and etc. Your contacts should be fine as the are stored on the SIM Card and if you have been syncing your contacts with your PC then they should get loaded when you do the up
I tried using a the google mail java app on my tmobile dash. It froze up on me, and when i turned it back on it just stays at the "tmobile" splash screen. I have tried using the soft key and power button reset but it doesnt work. What's weird is that it wont power down unless I take the battery out. It powers on, shows the tmobile splash screen, then freezes. Is there any other way to reset it or is it totally bricked? I bought it new off craiglslist so tmobile wont replace it for me cause I'm using it unlocked on cingular.
Ok bro I know I am a bit too late to help you with this problem but someone else may benefit from these directions. I see most places online only have half advice about this very common problem with T-mobile Dash.
This is what you need to do, you have to do a hard reset exactly like "reviel" mention. Also like he said timing is essential but the trick is that you need to show some patience through the process.
Note: Please read the directions completely before doing anything for better results.
Step 1: Take your battery out and shut off your phone Step 2: Press and hold the two soft key buttons. Step 3: Press and hold the power button for exact two seconds, 1001, 1002 and release, but continue to hold the two soft key buttons. Step 4: Within seconds a black screen with some text will come up asking you to confirm if you wanna delete everything; and right then you let go of your soft key buttons and press the green call button (also known as the "send key"). Step 5: You are done but not really, your job now is to find something else to do and leave your phone alone for at least 2 minutes. Eventually if you don't have a SIM in it, it will prompt you for it and you click the soft key to choose "OK"; also, it will ask you to confirm to restart and you click the soft key to chose "Done" for it.
Wait a minute for it boot up and overall it should do it.
This happen to me more than once, the latest today (may 25 08)at 9pm. Tmobile will tell you how sorry they are and that's about it. I am on my second dash and second battery.
Try to hold both top keys (between call green and hung up red) while you are pressing on the shut off switch for 2 seconds. Whe it comes back to life, everything will have erased but supposedly, the phone will be like new.
I am collecting names and emails of people who are fed up with the Dash and Tmobile. Write to me email@example.com
Mine does the samething. I'm running 6.1 and have found the problem to be the system fails to read the sd card on boot. When I reset my memory I don't put the sd card in until the system has booted back to the start screen. Works fine everytime.
when this happens take the battery off for 15 seconds and put it back. try to do this atleast once a week. cell phones is just like a computer that need to be reboot. let me know if this solved your problem.
Since it gets to the 90% boot phase, you should be able to synce with the computer at that point. If so, then downgrade to pocket pc 2003 software which you can find at
Once done, make sure your pda will boot. If effective, re-install windows mobile 5.0 and try it again!
(Last attempt b4 contacting manufacturer...)
I had simmilar problem with this on my pda at one time too. Sometimes it is as easy as removing the battery, pressing and holding the power button for 10 seconds, then putting everything back in and reboot it.
