title_body: Is it possible to jailbreak Kindle Oasis 2?
upvoted_answer: Is it currently possible to jailbreak it?
  
  
  Only if the original firmware (5.9.0.5.1 or 5.9.0.6.) of your Oasis 2 hasn't been updated. For more information see this website.
  
  
    If not, have there been Kindle e-readers before without jailbreak possibility, and has Amazon released the jailbreak possibility later?
  
  
  Amazon has never released any jailbreaks. Hackers have reverse-engineered the firmware and developed jailbreaks for specific firmware versions.
