Amazon has released a software update for 10th-generation Kindle e-readers that restricts device modding and prevents the use of third-party tools to remove digital rights management from e-books.
Key Points
- The 5.18.1.1.1 software update targets the Kindle Paperwhite 4 and base Kindle models to block jailbreaking tools.
- Amazon transitioned older e-readers to the KFX-ZIP format, which is incompatible with common DeDRM plugins and Calibre software.
- The company has discontinued USB file transfers and replaced the Kindle for PC application with a native Windows 10 and 11 app.
- These changes effectively prevent users from backing up their purchased e-books or modifying their device software.
