Kindle Voyage out of box 5.8.11 jailbreak

Hi,
I just bought a Kindle Voyage with 5.8.11 firmware out of box.
There are lots of threads, I can’t tell with thread I should follow because most threads are about KP3 jailbreak with OTA update.

Just wondering ask if the Voyage out of box 5.8.11 jailbreak? If possible, Which thread I should follow?

Thank you,
