after lots of default problems with my first jailbreak i had trouble trying to get cydia to install instalous. There where missing files trouble so i decided to reset and jail break. Half way through the reset the computer froze and the ipsw was impropperly installed. I tried to go back into dfu mode which for some reason it keeps coming up but the apple logo won't show and as a matter of fact itunes will not go past validating the restore. I cant even get itunes to do a factory restore... i get trouble screen 9134, or 1600 or 28. I have not dropped the phone or anything. oh and its the old boot. please please please help i can't afford a new phone and have to get it to work again.
