Hi, new user but simmilar problem. Ender 3v2, 422 board bought with v102 firmware. Updated to v111 BL touch but works poorly so ask creality service for latest soft. After update to v2084 got black screen so ask for a new scrin soft. Got DWIN from service but latest file inside was 03.2020 and after inserting to display slot it turns from black to blue and orange and stayed so. After reboot still black. I tryed to downgrade mainboard to 111 or 102 but still black (dont know if realized but used same card as for update with only one bin). Last attempt was to update by cura. Connect via usb, drivers seemed to install prop, display backlight on, BLtouch lights and pops out/in but cura cant see any connected printer. Service not responding for a few days. Any idea to help me??
