Why users with jailbreaks should not upgrade to iOS 11.2.5

A couple of days ago, developer Coolstar announced that most of the Electra tool patches will work with iOS 11.2.x.

However, he recommends staying on iOS 11.2 to iOS 11.2.2 as Apple has made many security changes in iOS 11.2.5.

He's writing:

If you have 11.2 – 11.2.2, do not update. Some Electra patches may not work in 11.2.5. And versions 11.2 – 11.2.2 require only the “tfp0” exploit.

It looks like iOS 11.2.5 has made a HUGE change to the security system. Versions <11.2.2, on the contrary, are similar to 11.1.2. Also, find_port() was removed from 11.2.5.

Apple improves system security toit was harder for hackers to create jailbreak tools. It's like a cat and mouse game. It is not surprising that the company continues to improve precisely the security system. It is not clear for what reason changes were made in iOS 11.2.5: to protect against jailbreaking or to fix any bugs.

One of the main rules of jailbreaking is not to upgrade to new versions of the system. IOS updates reduce your chances of jailbreaking. If you have iOS 11.2, iOS 11.2.1

Coolstar has already released an Electra version with Cydia for iOS 11 for tweak developers so that they can prepare updates. Soon, the instrument will be released publicly.
