4 logo screen freeze on sidekick 2008

when i turn on my sidekick 2008 the four logo screen comes up(circle, menu,x, and check).and it just sits there for about a minute and then just restarts it self..then after a while it jus goes to the screen that has the picture of a sidekick with two x's as eyes and stars around its head

p.s. i already did the 1, 0, and @ reboot and already took battery and sim card out and let it sit for a while to..any other suggestions anyone!?
