Samsung Focus not working :(

view story

http://forum.xda-developers.com – My Samsung Focus is stuck on a blinking Samsung Logo screen (black, with just Samsung writing). It has been stuck like this for the past twelve hours or so, and I have attempted to take the battery out for half an hour before replacing it, as well as a hard reset and simply restarting the phone. Nothing works, as it stays on the blinking Samsung Logo screen. The hard reset screen just flashes for a second before returning to the Samsung screen. Even after letting the battery die and then charging it, nothing has changed. Do I need to replace the phone? Is there any software I could downloa (HowTos)
