I hope this is the right place to post this. I am using an HTC Desire running Android 2.2 from the Telus OTA update. I wanted to see the OS without the Sense UI so I went through Settings/Applications/Manage Applications select 'All' selected HTC Sense and hit the 'Clear defaults' button, it did nothing when I went back to the home screen, so I went back and 'hit 'Force stop' the phone restarted but was still using the Sense UI so I shut it down and tried to restart it immediately after the screen went black. The phone then vibrated 4 times in a row and did nothing. After that the phone would not start. The only thing I could do was remove the battery for a few seconds put it back in then start the phone up. Now I find the phone has an issue where if I don't give it a few seconds after shutting down it will do the 4 vibrates and then do nothing. The 'Clear defaults' option in the Sense UI is now always blocked out so I can not select it. Has this happened to anyone else? Is the vibrating then becoming a paper weight an issue due to the Sense UI issue or is that normal because I may not be giving it enough time to shut down or something?
