I just "repaired" an iPod Touch, 4th generation (MC540BT). A friend of mine didn't use it for a year because it didn't charge. After playing with it a little; I finally managed to turn it on and it worked. She (my friend) told me that it didn't work as soon as she updated it to 6.0.1 and asked me if I can downgrade it to the previous version. I told her about hard reset but I want to know if hard reset brings it back to the iOS version that it left the factory with.
In less words: Does a hard reset downgrade device or allow me to downgrade?
