Officially…. No. Apple stopped signing 15 a long time ago.

Unofficially, yeah you could find the right iOS file etc etc, but that requires knowledge of the subject. How confident are you with computers?

Poke around forums and see if anyone has a signed copy of iOS 15 ipsw’s. Chances are slim but possible. From there just look up how to restore manually from a designated ipsw via iTunes.

I usually get my IPSW files from ipsw.me

My days of fuckin with non-public software files are behind me. I stick to the current release for peace of mind. Good luck in the hunt

I believe you will also need blobs. The JB subreddit might be able to help with that.
