This method involves flashing the rootfs partition via the USB Type-C port on the Go2 device, thereby replacing the existing partition. Typically, the flashed rootfs already has root access enabled, with known root credentials (root:theroboverse) for subsequent SSH login.
Before proceeding with any further procedures, it is highly recommended to first determine the Secure Boot status of your Go2 device and perform a full backup (only for non-Secure Boot Go2 devices).
Flashing a custom rootfs is available for both non-Secure Boot and Secure Boot Go2 devices. Follow the manual for instructions. This is currently the only available method for Secure Boot devices.
