recently I download the latest raspbian (2020-02-13-raspbian-buster-full.zip) . run it on RPi 3 B model. found it won't boots to desktop. is it backward compatible?
thanks

How did you (try to) install "2020-02-13-raspbian-buster-full.zip" on that uSD card (ie. with what tools and on what computer etc.)?
My God! it's power supply issue! I switched another power supply. then it worked. I have many usb power unit. I thought they are same, so I just grab one for RPi. it lights up RPi, seems no problem. but it is problem! I tried many, many times. finally come here for help.
