ok guys I NEED HELP.

i updated my nokia n900 firmware with the PR 1.1, and now it wont start up.

after updating my phone screen turned blank, i left it for a couple of minutes but nothing happened so i left it again for a couple more minutes but still blank screen.

i turned it off and now when im trying to turn it on it just shows the nokia logo, then the loading animation then, BLANK SCREEN.

i dont know what to do with this!! my hair is starting to fall off right now! lol

HELP ME i dont have any other phone to use today!
