iOS 12.1 has already been out for a week, which means there isn’t much time left to downgrade to iOS 12.0.1. Given the potential jailbreakability of iOS 12.0.1, you should consider downgrading via iTunes.
Now that nitoTV has been released Apple TV jailbreaking is more powerful than it’s ever been. And with tvOS 10.2.2 still being signed, Apple TV 4 users can downgrade, jailbreak with greeng0blin, and experience it now. But should you?
The clock is ticking on signing for iOS 11.1.1/11.1.2 and tvOS 11.0/11.1, so the pressure is on to save blobs for those firmwares, as well as to possibly restore to them. This doesn’t apply to everyone though, so check out our advice on the topic!
Update: tvOS 11.1 and iOS 11.1.2 are now unsigned. DO NOT ATTEMPT TO RESTORE TO THEM!
If you want to someday jailbreak your Apple TV 4, you’ll need to restore now to tvOS 11.1 and then block all software updates. This guide will show you how to block automatic updates, prevent it from downloading updates ready to install, and prevent update prompts appearing.
Good news for owners of the iPod touch (5th generation), Apple TV (3rd generation), iPad mini, and iPad 2 (iPad2,4). The posting of decryption keys for these devices means eligibility for all sorts of 32-bit downgrade and dual-boot tools.
