Hacking the Kindle Paperwhite 4 was a matter of when it would be jailbroken, not if. It’s still a little surprising to see the brand-new Paperwhite 4 unlocked so quickly. The guide for unlocking the 2018 Paperwhite will seem familiar to those who have hacked the Paperwhite 3. Many of the steps in the process are similar.
Benefits of jailbreaking the Paperwhite include customizing the lock screen image, custom fonts, and the option to install KOReader. KOreader is a document reader for Kindles and other E Ink devices that allows users to open and read PDF, DJVU, CBZ, FB2, TXT, HTML, RTF, CHM, MOBI, EPUB files. KOReader is the key to accessing ebooks and other documents acquired outside of Amazon’s ebook ecosystem.

Modding, hacking, rooting, or jailbreaking any device carries a risk of bricking or disabling the device, so read any walk-through thoroughly and research backup methods before attempting to jailbreak your Paperwhite or other devices.
