Jailbreaking

I was able to jailbreak my Kindle Paperwhite 5 (2021) with AdBreak according to the instructions from this site: https://kindlemodding.org. It is the "jailbreaking wiki". The only tricky part was enabling the ads (AKA "special offers") on the device. Apparently, Kindles sold in Poland do not have ads, so I had to move my account to another country (Germany) to enable them. After that, the jailbreak process was straightforward. After jailbreaking I moved my account back to Poland with no issues.

This site is also useful and contains some post-jailbreak information: https://kindlemodshelf.me.

Software Iโ€™m using

  • KOReader. Installing KOReader is the main goal of jailbreaking.

Misc

  • Converting screensavers to Kindle format
