iOS 11.2.2 Jailbreak Tool Might Arrive As CoolStar Suggests Avoid Upgrading to iOS 11.2.5
CoolStar, the developer of Electra jailbreak, through his official Twitter page (which looks deleted now), has suggested that anyone on iOS 11.2 – iOS 11.2.2 should stay there and avoid iOS 11.2.5 upgrading.
CoolStar’s Electra jailbreak tool gives device freedom for Apple’s 64-bit devices running on iOS 11.0 – iOS 11.1.2. That is made achievable due to Ian Beer’s async_wake exploit from Google’s Project Zero, in addition to the post-exploitation patches made by CoolStar. Electra developer hints that it is probable that those post-exploitation patches are compatible for iOS 11.2 – iOS 11.2.2 jailbreak.
If you’re on 11.2-11.2.2, stay there..
It appears 11.2.5 might break Electra’s post-exploitation patches, whereas 11.2 – 11.2.2 just need a new tfp0 exploit
Also: looks like iOS 11.2.5 changed a LOT on the security side. <11.2.2 is very similar to
11.1.2 however. find_port() is removed on 11.2.5
Electra jailbreak, currently, is not well-matched with iOS 11.2 and beyond but the tweets of CoolStar clearly hint that there is a hope of hitting that level of compatibility with a new tfp0 exploit. The tweet explains that iOS 11.2.5 makes enough internal changes to break the post-exploitation patches within the Electra jailbreak.
CoolStar’s tweet suggests that Apple is developing the security of iOS to make it more difficult for hackers to jailbreak it. So, it is highly probable that they continue to make significant changes on the security side of iOS. However, it is yet not clear if Apple has actually made these changes in iOS 11.2.5 considering the iOS 11 jailbreak, or just to improve iOS security.
Overall, if you want to jailbreak your iOS 11.2, iOS 11.2.1 or iOS 11.2.2 device then you are advised to stay there and avoid updating the iOS 11.2.5 or iOS 11.3. This will actually improve your chances of iOS jailbreaking.
