Downgrading to 11.1

[Sift]

I downloaded the ios 11.1 software way back when it was still being signed. I want to downgrade my iPhone 10, running 11.2 so I can jailbreak. Would I still be able to downgrade, or will iTunes not allow it?

You can only install an iOS file that is currently being signed.

I know that... I downloaded the ipsw when it was still being signed last year, but I never got around to downgrading my device. My question is can I still downgrade with that ipsw, as it was downloaded before signing stopped?

Nope. You see, even though you downloaded while it was still signed, the keys that they are signed with expire.

No. The only way you would be able to install it is if they start signing it again.

No, as it is no longer being signed.

No but I did hear you could do something if you saved shsh blobs but I’m honestly not sure what or how that works...

That hasn’t worked in years. And that requires being jailbroken first.

Ok just seen where a YouTuber said you can save shsh blobs and downgrade. He’s a well known youtuber tho.

It now also works on A7 devices to downgrade to iOS 10 but of course it requires a jailbreak along with saved blobs.

Would that be one of the now quite old EverythingApplePro videos? Because when he said that it was because one of the jailbreak developers had hinted at a tool that could downgrade you with those blobs, but that tool, to my knowledge, never came out
