Amazon Fire TV Cube Exploit Lets Users Gain Root Access and Unlock Bootloader

A community release provides an owner-operated exploit package for third-generation Amazon Fire TV Cube (gazelle) enabling temporary privilege escalation and a bootloader unlock to install Magisk, TWRP, unrestricted fastboot, and Amlogic download mode on supported PS7717 and earlier firmware. The process requires ADB debugging, can permanently brick the device or trigger a factory reset, disables Amazon OTA updates, and expands possibilities for custom recoveries, kernels, and multiboot while the documentation notes no evidence of remote exploitation or active malicious use.
