When FutureRestore is used to downgrade the iOS version, the components in two different IPSW files containing two different iOS versions will be merged. If you want to downgrade from iOS 14.6 to iOS 14.3.
Then there needs to be a kernel vulnerability. You can set the Nonce generator from the inside of the saved SHSH2 blob, which needs to be combined with the following contents: iOS 14.7. 1 is the latest version, and iOS 14.7 has been signed. You will be able to use iOS 14.7 or iOS 14.7. 1 (the version I tried to downgrade to).
-iPhone 6S and later latest signature iOS version: iOS 14.7. 1.
The latest signed iOS version of iPhone 5S and iPhone 6: iOS 12.5.4.
SEP compatible baseband in iOS 15 Beta 4 can be used to downgrade iOS 14!
However, within the range of iOS14.0-14.7.1,there may be problems in restoring the version of A 12-A 14 before v225 in the future.
These problems have nothing to do with SEP/BB compatibility. Please use futurestore v 225(beta) or later to solve this problem.
IPhone 12 series-sep and baseband compatibility range from iOS 14.7. 1 to iOS 14.0 (in between). When using the older FutureRestores (e.g. 222), FDR errors are reported on A 14 many times. Always use the latest beta.
IPhone SE 2- SEP and baseband are compatible with iOS 14.7. 1 to iOS 14.0 (in between).
IPhone 1 1 series-sep and baseband are compatible with iOS 14.7. 1 to iOS 14.0 (in between).
IPhone XS series (including xr)-sep and baseband are compatible with iOS 14.7. 1 to iOS 14.0 (in between).
Note: Before trying to downgrade, you need to study whether the SEP and baseband of the currently signed version are compatible with the version you are trying to downgrade. Otherwise, the downgrade may fail and damage your device.
This morning, "MOSEE 202 1 Mobile Security Technology Summit" held a press conference. In the meeting, some research on utilization rate was mainly shared. It is mentioned that there are more ways to use iOS devices, and you can also bypass sandbox detection to achieve jailbreak operation.
At the same time, the speech at the technology summit also brought a huge iOS jailbreak operation surface, and the technology summit also led to a variety of iOS jailbreak operation methods to bypass Apple's increasingly perfect vulnerability mitigation scheme.
Finally, a screen shot of jailbreak of iPhone 1 1 Pro mobile phone iOS 15.0 beta4 was released on the press conference screen.
At present, the jailbreak of iOS 15 system has not been made public, and only people at the conference can see it. Because the press conference is not over yet, it is estimated that you will see it when it is over.
Seeing this, we know two things:
① Pangu team will not release jailbreak tools.
② There is a jailbreak vulnerability in IOS15.
From the above, we can only wait for the development and research of the jailbreak god, so jailbreak will not die, but still exist.
As for upgrading to iOS 15 and other jailbreaks? I suggest not to do it for the time being, and keep it in the iOS 14.4 to 14.7 system first. Anyway, the lower the system, the more hopeful it is to escape, rather than upgrading the highest system to wait for escape, which will be further.
Say it again! Some netizens found that updating Coreutils plug-in may cause problems in Sileo jailbreak store.
On this issue, you don't need to downgrade Coreutils plug-in, just update the version of Sileo 2. 1.2.
That's all for now. In other words, the partners expect that the ios 14.6 version will not be jailbroken. Do you expect the current version of iOS 15 system?
