iOS 8.3 Downgrade No Longer Possible As Apple Stops Signing iOS 8.2
There’s always a short period after an iOS software release whereby the previous firmware version can be downloaded and installed with little incident. After this initial grace period, however, the older software is completely frozen out, and with iOS 8.3 being the most recent public build for iPhone, iPad and iPod touch users, the preceding iOS 8.2 has officially been cut off.
Often, we’re sad to see the signing of an older firmware cease, since, for example, said version may be jailbreakable. However, not only is iOS 8.2 not susceptible to any exploit – if you discount the first two betas that can be jailbroken via TaiG – but it’s perhaps the buggiest release under iOS 8, aside from the marked disaster that was iOS 8.0.1. Thus, even if you are partial to a Cydia tweak or ten, it shouldn’t negate the fact that iOS 8.2 is going to cause you plenty of problems, and so while iOS 8.2 is no longer being signed by Apple, you ought not shed a tear.
Jailbreak guru i0n1c, as you may or may not have already caught, has demonstrated a legitimate iOS 8.4 jailbreak, and while it’s unlikely that the German hacker will release this gold to the public, it may be enough to encourage other would-be jailbreakers that there’s light at the end of the tunnel. After several jailbreaks through TaiG, Pangu and PP, the scene has hit something of a plateau, but with i0n1c’s efforts and the progress surrounding TinyUmbrella, here’s hoping that there’s more to come from the jailbreak community this side of iOS 9.
So, the take-home here, guys, is that iOS 8.2 is no longer being signed. Hence you can’t downgrade to it from iOS 8.3 if for any reason you wanted to. There is no advantage of downgrading to iOS 8.2 either since there is no jailbreak available for it. If you are on iOS 8.1.2, it is best not to update to any new version since the last jailbreakable version currently is iOS 8.1.2.
