I downloaded this image ( Armbian_21.05.1_Rk322x-box_focal_current_5.10.34_xfce_desktop.img) and placed it in the images folder in multitool, and it worked perfectly on my mxqpro 4k rk3229,but now how do i do if i want to run the same image but by sd card ? i dont want to lose my android installed in emmc/nand, could someone do a step by step please?
