Hi, how to best jailbreak an Oasis??

Hi, my mother and my brother bought me a new Kindle Oasis this Black Friday, so I want to know how to really make the best of my old Oasis before opening the new one.

So I want to know how to Jailbreak my Oasis in the best and safest way.

The only thing I really want is to be able to get all my Oasis Collections into Calibre so I can manage them the way I used to do with my Kindle keyboards!!

Please help me!! Thanks, Happy Holidays and be well :), Monica :sweethear
