There is no single “71.2” firmware for all MXQ Pro 4K boxes. The version number often refers to the build date or board revision . Before downloading anything, you must identify your exact PCB board version (e.g., S905X, S905W, RK3228, or R329). Opening the box and reading the markings near the RAM chips is non-negotiable. Using the wrong firmware = hard brick.
