every time i try to restore my iPhone back to its original state, i either get a a 3194 error or a 1600. So i used to applications called tinyumbrella, and ireb. When i use those to programs i don't get those errors and it starts to restore the iPhone, but as soon as it finishes iTunes says the phone needs to be restored again. I tried downgrading my firmware from 4.3.5 to 4.3.3 but something went wrong. is there any way i can restore this back to its original os.
