-The device does not allow the user to flash firmware, does not support settings backup and restore, and does not provide access via SSH. The SSH server (dropbear) cannot start due to misconfiguration. And even if it could, the admin user shell has been replaced with a limited router configuration tool. Accessing the serial port seems to be the only way to root the device, but this is an extremely painful process. Once the hardware issues are sorted out, the device is not protected: the bootloader can be interrupted, and also once the router has booted up, pressing enter drops you to a root shell.
