What happened?
A public exploit package now lets owners of Amazon’s third-generation Fire TV Cube gain persistent root access and unlock the bootloader on firmware PS7717 or older. Released by XDA developer Pro-me3us, the project targets devices known as “gazelle”. It combines temporary root access with a separate bootloader flaw to enable deeper system changes. According to the XDA development thread, the unlock installs Magisk and TWRP recovery, opens restricted boot options, and supports alternative operating systems. However, the developer warns that the process can permanently damage the device.
