Can I downgrade to iOS 10.3.3 by jailbreaking it to that version from iOS 11.0.3?

My iPhone 6s Plus decided to update to iOS 11.0.3 on its own. I lost the use of many of my favorite apps and a lot of data in those apps. Is it possible to jailbreak the phone by downgrading it to 10.3.3?

It currently isn't possible to downgrade from iOS 11 to iOS 10 or lower as the SEP isn't compatible. Even if it was, you wouldn't be able to unless you saved the SHSH2 Blobs for iOS 10.3.3 while it was still being signed.

Your only option is to wait for an iOS 11 jailbreak.

You can't downgrade 1st of all.

If you somehow manage to do so, then yea I suppose you could jailbreak it.

Is the answer that you can downgrade if you have an iOS 11 jailbrake? I have the same issue and do not have the 10.3.3 Blobs. Are the SHSH2 Blobs unique to each iphone/ipad or can you use another blob from a similar device?
