    I have the exact same problem. I called and they told me to replace it. It wasn't under warranty anymore so I was SOL. 

  • viproka76 May 14, 2008

    my t mobile dash with s/n:sz704fe15082. also does not start. It was operating very good at the begining and then one it was out of battery then I charged it and the next time I put it on It did not start. The only think which it does is to show t mobile screen then show the Direct Put technolgy. That is where it stack. I can not use it. Please help.

    my t-dash goes to the first t-mobile screen, then the windows screen, then freezes and goes nowhere...

  • s0ldi May 17, 2008

    Same issue as described in the original post. No solution found, but posting in case _someone_ from HTC is watching or someone has a solution.

    Sorry, no over-dramatic post and exclamation marks here.

    My TMobile Dash turns on and then turns off soon after, then i took out the SIM and it worked fine. what can i do to fix this?

  • AOS9010 Jun 29, 2008

    Better solution than resetting and this worked for me is to remove your storage card and replace it once the phone has booted, someone told me that the reason it goes thru this loop is because of programs installed on the storage card. I'm unsure as to how accurate that is but it did fix the problem for me without any adverse effects so I thought I'd recommend it

    my phone keeps restarting even after i removed sim card and memory card.

    what can i do next?


  • Joyride Sep 25, 2008

    Very Strange- The phone communicates with the network when you boot it up. I've been wrapping it in foil to reboot for over a month. This worked OK. I'm glad I saw this post, removing the SD card also works. I uninstalled every program that I had and deleted everything on the card, but if the blank card was in the phone, it still had the same boot problem.

  • arabon Sep 25, 2008

    I've had the exact same problem for over a year, even with hard resets and deleting everything on my Dash and starting from scratch. Now, even with the SIM and Memory cards out I can't get it to turn on at all. It gets stuck in a white T-Mobile screen. I don't want to do a hard reset until I can get my Outlook contacts synced off of it and I don't know what do to!

  • Anonymous Sep 25, 2008

    Took out the sim-card and tried another person's battery and still in the infinite boot sequence mode. Not sure what next to try.

    Same problem - phone went dead from battery power and turned itself off. after recharging could not get the phone to work. Power button just sends the phone into a recycling of T Mobile and Windows Screens.

    I had the same problem. Took the SIM out and restarted the phone. Now I have a new problem, all my contacts are intact BUT my calendar is cleraed out. Which really isnt a big problem at all.

    Same problem. Tried removing battery and SIM card, but to no avail. Left it in a corner for a whole day, it wouldn't come out of the endless reboot cycle. REMOVED THE STORAGE CARD and rebooted and IT WORKED!

  • Oregon503 Dec 26, 2008

    Thank you s0ldi ... your solution worked just as you said and I'm so grateful to you for taking the time to post your answer for lost technophobes like me! :)

  • kkalanik Jan 04, 2009

    Dash goes thru Tmobile screen to Windows screen and just stops. Tried removing sim card, then sim card & storage card. Still nothing when trying combination of holding down soft keys while turning on, etc. Will try leaving sit with the battery out for a while I guess.

    Any other suggestions?

  • jen6604 Mar 01, 2009

    Mine did the same thing as others...just kept recycling the start up and shut down T-mobile screen and Windows mobile screen, as I read this and popped out the additional STORAGE card...not SIM, it powered up perfect! I'm keeping my fingers crossed! Thanks a million! Tech support wanted me to exchange the brand new phone...I bought the new one because of the very same prob. with my old Dash!

  • confi2000 Mar 20, 2009

    I had the same problem, Dash gets on and off into WINDOWS LOOP and won't start even if you remove battery for few hours and/or SIM card. What really works is to remove the storage card and then start it without it. Once the Dash starts, switch it off, put the storage card back and re-start your Dash again. VOILA ... you will be back and running. My guess that the problem lies in the compatibility with another program and in my case it is PHOTO CONTACTS PRO because the pictures of the Photo Contacts Pro are stored in the storage card. In another words, the problem isn't in the DASH itself but in the WINDOWS 6.0. I just wish that the DASH would be based on MAC ...

  • azhar_aziz Mar 26, 2009

    despite of removing the storage card it does'nt get out of the cycle of rebooting. Taking out SIM and replacing it did'nt help either.
    how do we hard boot it. How do we do that?

  • Moonhacker May 16, 2009

    I replaced my dash 4-times!!! The only reason why I kep replacing it because it was the windows solution for my job. I really like the phone. But after realizing that the problem was not going away after placing it-I decided to trouble shoot the problem myself. It will indeed start once the card is pulled out, however it becomes a pain after a while pulling the case off my dash to take the card out and put it back in once started. I was relieved to see that I was not the only one having the same problem, however now I'd like to know why the card is a problem. I thought that it was programs that were installed on the card, phone contacts as well, however I'm not sure. Once I find out I'll check back.

This will fix it:

Turn the phone off, remove the battery for a minute. Replace the battery.

Hold down the right and left soft menu keys simultaneously then press the power button for a couple seconds and release. Keep holding down the soft keys until the hard reset screen displays.

The reset screen will tell you to press 'Send' to reset or any other key to cancel. Press and hold 'Send', which is the button with the green phone on it. After a couple seconds, the device will start to do its thing.

This will take some time so be patient. It will have a question or two as it goes through the process. Answer.

Don't worry, you won't lose your branding (e.g. if you are a tmo customer, you don't lose the ability to have myfavs and your phone keeps the tmo branding/settings).

Removing memory card fixed the problem with mine.

Posted on Oct 25, 2008

I had the same problem. I just replaced the battery, and it fixed it for me. the original battery gave out on me after about 7 months. Go to a t-mobile store and ask them if you can test a different battery in your phone.

After making sure I had the SIM card seated properly I turned the Dash on and left it cycling to drain the battery. My battery is old and I recharging it with the car charger gives it a hotter charge. I suspected the battery voltage was dropping below minimum threshold when the phone was being booted up, forcing it to go into its shut down routine, allowing the voltage to climb sufficiently to re-initiate the boot sequence, thus putting the Dash it the "boot-up/shut-down" loop condition.

I checked on my Dash a few minutes later and found it happily blinking green.

Solution: Like with an annoying child that won't stop crying, find the patience to put up with the annoying T-mobile start-up jingle and put your misbehaving Dash in a corner till it decides to get with the program. WORKED FOR ME!

For those that have problem with Dash turning on and then shutting off ----

I had the same problem only to discover that the SIM card was not placed in the slot as it should be. Try adjusting the SIM to fit correctly. This will work

S0ldi has it right, you need to reset the phone. My problem was that resetting didn't work. In order to reset mine, I had to remove the sim card and the media card. Then, holding the soft keys as stated in solution one, I turned on the phone and waited a couple of seconds.A black screen with text came out and then his send. Viola! My phone worked again. Remember to backup you phone numbers and important data, doing this will wipe out everything. Hope this helps those who couldn't reset the phone.

To update your T-Mobile Dash Smartphone, please follow this steps,

1. Download the new software to your PC. You will be instructed to enter the 15-digit IMEI number for your device to access the download.

2. Ensure ActiveSync 4.5 for computers using Windows XP or earlier or use Windows Mobile Device Center for computers using Vista and Windows 7 is installed on your PC.

In order to sync your iPAQ with Windows Vista or Windows 7, you will need to download and install Windows Mobile Device Center 6.1 from

  • To find out whether your version of Windows Vista or Windows 7 is 32-bit or 64-bit, click Start, right-click Computer, and then click Properties. The version is listed after System Type.
  • You can use Windows Mobile Device Center 6.1 only with phones running Windows Mobile 2003 or later.

(To see which Windows Mobile operating system you’re using, and if your phone doesn’t have a touch screen, click Start > Settings > About. If your phone has a touch screen, click Start > Settings > System tab > About.) To sync content to any of these devices, you must use a USB or serial cable and your computer’s Internet connection and File Explorer.

  • You must use a USB cable to connect your phone to your computer the first time you use Windows Mobile Device Center to sync.

Please help me to fix my problem

means your firmware is corrupt. the only way to get you back in your device is to do a hart reset via your sw keys.....

WARNING, This will delete everything that is stored on your device, and unless your computer can recognize your device, you wont be able to get it back.

in order to the the software reset, the device needs to be fully off. preferably, take the battery out of the phone before you get started.

press and hold the 'soft keys' (buttons above the back arrow and home keys, they have a line on them) and hold those down. while you are doing that, press and hold your power button for about 3 (three) seconds and release the power button. the phone should begin to turn on but then it should go to a black DAS screen with white writing. at this time you can release the Soft keys.

press the green call button to reset the device. it will reboot and you should be able to get in your phone. if this fails and if the computer does not recognize the device, you will have to contact either your phone provider or HTC to replace the device.

do a sw reset....its possible it was damaged when it was dropped in the water, but not likey....

turn the phone off, press and hold the soft keys (buttons with the lines on them above the home key and back arrow key) and hold it the power button while you are doing that until the white t-mobile screen will come on, then instead of going to the green windows mobile screen, a black screen with white the green will get you in your phone but it will erase your info as a result....
