Ok so my dad recently bought an iphone 4s from someone that was selling one. When we turned it on we noticed that it wasn't restored to factory settings and there was still many apps on it. So i tried to restore it by going into settings but it asked for a password. Well i tried 1234 or 0000 but none of them worked. So i proceeded to connect it to my computer and restore it through itunes but my computer wouldn't recognize it as an iphone. When i connect it, some weird usb config thingy shows up on the iphone 4s and asks for around 5 options: mass storage, java, webcam, and some other ones. I think its jailbroken but i literally have no idea how to restore this thing. I tried hard resetting it but when i hold the power and home button it just won't turn off. Even DFU mode won't work. At this point i am completely lost and pissed off, i don't know what kind of moron had this phone before but its driving me nuts trying to figure out how to reset this ****.
I'd really appreciate it if someone could help me
