How do I rollback my version of Flaresolverr?

[Chopper3280]

My flaresolverr was working and I very stupidly updated it in my truenas jail. Now it no longer works with prowlarr. Can someone please provide a step by step (I'm a moron) to download and rollback my flaresolverr to a version that works. From what I've read, ver 1.2.9 works. Any help is appreciated.

Rollback your jail to the snapshot you took before updating?
