@rafman I try install miniarch or armbian to my device X96q based on h313 and memory chip samsung KMR82001M-B609. I recorded the image on an SD card, inserted it into the device, pressed the button in the AV input and turned on the power. The X96q splash screen appeared, quickly disappeared and nothing else happens. If i dont press the button, box start with android. How can i start from sd card?
