You may have heard about Prometheus tool that we’ve published in our last report. It helps users to downgrade iOS firmware to older firmware using SHSH Blobs.
Every new firmware have some bugs and vulnerabilities. Suppose, those exploits are useful for jailbreak iOS 10.3.1, then it’s great, but if it harms you, then you should downgrade iOS 10.3.1 to the previous firmware update whatever best for you.
As iOS 10.3.1 is under lab testing and beta stage, users who wanna downgrade 10.3.1 need either iTunes or Prometheus downgrading tool. But before starting with Prometheus, you should check compatibility issues related to this software.
Downgrade iOS 10.3.1 to iOS 10.3
Yeah, this firmware can be downgrade to iOS 10.3 without any issue until Apple stops signing iOS 10.3. You can use iTunes also to downgrade iOS 10.3.1 to iOS 10.3 and there won’t be any issue or problem because Apple still signs iOS 10.3.
But at the same time, you can use Prometheus tool to downgrade iOS 10.3.1 to any firmware you want. You just need to update it to the most latest and updated version.
Can I downgrade iOS 10.3.1 to iOS 10.2?
At this moment, it would be difficult to say that you would easily downgrade iOS 10.3.1 to iOS 10.2 because at this moment, Prometheus won’t support downgrade 10.3.1 to iOS 10.2, it would need update for it.
Additionally, you won’t restore iOS 10.2.1 too. Apple signing method is reason for it. Apple has stopped signing iOS 10.2.1 too. So, you can restore iOS 10.3 officially from iOS 10.3.1.
Update: Apple stopped signing iOS 10.2.1 completely. Without using Prometheus, now users can’t downgrade or restore to iOS 10.2.1.
