I was trying my application on HTC Desire when I realized there was a problem with the app so I force stop it. Next thing is the screen freezed - HTC white welcome screen. I tried rebooting several times, but it never got into the desktop. Sometimes it restarted itself. I tried removing the battery as well to no avail. Now my phone is completely dead. I cannot turn it on and when I charge it, the red/green light is not on. What should I do? I was thinking of resetting the phone via command line or something like that. Thanks for any suggestions!
I don't know what your app did, but I find it strange that it is no longer booting. I would suggest trying to get your device in to recovery mode. I have never done this on a non-rooted device so I am not 100% sure you can do a factory reset from the "stock recovery". But I know you can do it on a rooted device.
I found these steps, but again, I am not sure if this pertains to only rooted devices.
- Turn your desire off, Now hold the volume down and power button in to boot into hboot.
- Now use the volume button to navigate to boot recovery and select it by pressing the trackpad button.
