Iphone stuck on apple logo and WILL NOT restore!!!!!! :( :(

I'm not sure if this question has been asked before but I NEED HELP!! My Iphone was recently not able to sync on Itunes. Everytime I would try and sync my music it would disappear from the itues menu but still say 'syncing'. Then I tried to restore it after this failed (by getting an error message) I tried to re-jailbreak it and now it will not leave the Apple logo. I've tried everything I know, hopefully someone else knows something. PLEASE HELP!


PS. I Have an Iphone 3g with 3.1.2 firmware on it I believe.

I tried DFU too. Like basically nothing is working. It is able to go into restore mode and DFU mode but it just won't restore it in these modes. And I don't mind losing the jailbreak at this point. I can do that over, I just don't want a bricked phone.

THANKS! I don't know why I didn't think of that. I plugged it into a different computer and it restored with NO problem. Now to jailbreak it again.
