Hello, i have an iPad 4 (IOS 7.0.4) that hasn't been used for a very long while, so, i would like a bit of help before i screw it up... How can i upgrade to IOS 8.4? i don't want to upgrade to the latest version or IOS 9 because i wouldn't be able to jailbreak a 32 bit device, so any way i could upgrade it to 8.4 (Even though it says IPSW is unsigned)? Would downgrading to an older iTunes help? and then how do i Jailbreak it? Or is it recommended that i upgrade to a different IOS? if so then why? Any help is appreciated, thanks in advance!
