i have a iphone 4s that was jailbroken. i deleted the jailbreak but after that it was stuck in a bootloop. now whenever i try to update or recover, itunes tries to install it, but as soon as you see the install on the iphone, the logo goes pixelated and the phone crashes. then it gives an error on itunes. i've got this phone from my father and have no money so i hope someone can help me.
