IM SORRY: boot logo loop...again

so i posted this in the troubleshooting section, they said post here. so here we go lol

okay so first i want to say im sorry for posting this, ive seen soo many of these post im actually getting sick of reading them but non the less here i am lol. ok so naturally like the title says my iphone is stuck in the boot logo loop with loading cirlce. next:
ive tryed dfu mode restore
ive tryed recovery mode restore
ive tryed re-jailbreaking it
everytime on the initial load it gets stuck in the loop. when i connect it to itunes it see it and lets me add music, pic, vids..whatever i want,i can even sync it but while it lets me do all this im still stuck at the boot logo. so yea ive tryed all i can think of, any help would be greatly appreciated.

oh yea prop should have said this if it help, it was jailbroken using www.jailbreakme.com. also its actually my friends phone and he said he ended a call and put the phone in his lap, a couple mins later he pick it up and when he went to slide to unlock it froze then restarted aand got caught in the loop

but yea help plz lol
