How To Recover Jailbreak PW1 w/Screen Grab

Hello!

Here's my situation:
–I have a PW1.
–It was upgraded to 5.6.1.1 and I lost Jailbreak which I used for Kindle Collections (!!! So Crucial!!)
–I jailbroke at the end of 2014, and quite simply don't remember what the heck I did.
–I am a Mac user. I have access to a Windows laptop, but uhg, I'm all thumbs on it.
–**I'm attaching a screen grab of the folder contents of the Kindle, which includes some JB info.

Any advice much, much appreciated.

Thanks Mnanda
