ok so recently i ran into some trouble on my ipod.I rebooted it while i was installing something on my ipod from cydia and it got stuck on the apple logo.So i had to restore and update my firmware to 6.1.3 D; and i want to know how to downgrade. I am not to techy and ive looked on youtube and it says you can downgrade if you have your SSH blobs saved.....I have no clue what or how anyways i dont think i have them saved on my computer but ive been jailbroken before so if ive been jailbroken can i downgrade???? Thanks
