bad flash et4 pro?!?
Posted: 2021-01-11 4:33
Hi, I am an anet et4 pro owner. Yesterday I updated the firmware by putting the open source marlin found on this forum. I flashed the new firmware via stlink but once the printer is turned on, only the white display appears. I later tried to flash the original firmware but nothing. Is it possible that you need to restore the bootloader? if so how? thanks
