Trying to connect to iTunes but the computer does not detect the phone
So I bought this used iphone 5s. It was stuck in recovery mode and he gave it to me for 100$. I think I got scammed. Anyways, the phone when turned on shows an apple logo for a split second then connect to itunes logo but when i connect to my computer, it doesnt even detect it. Its not like device not recognized, I mean not even usb connected sound on my computer. I tried different computers, still the same thing. Is there anyway to restore this phone? Thank you.
