Hi. My printer is Ender 3 V3. I rooted and used the helper script for customize. I installed the Guppy Screen which is not worked properly and i tired to remove. Unfortunately now the screen is show the creality logo all the time and ssh login is not working. Tired 2 different computer to connect by ssh. Printer reboots not helped. The printer is working fine except the screen. How can i reset to factory settings or reinstall the firmware without the screen? I found the Creality firmware-recovery-tool but i cant find driver for ender 3 V3. Can i get a help. Regards, Balazs
Hello @baliboy79 …! 
Welcome to the Creality Forum…! 
Sorry this happened…
The only suggestion I would have at this point is to maybe try to unplug the machine and let it set for a few minutes.
Plug it back in and see… You never know…
Yes i tired. The printer was unpluged more that 20minutes. not helped 
can you reflash the firmware, i havent got one but i assume like the KE there is a way to flash via usb and they have firmware files on the site for the V3
Hi. Do you know how can flash the printer without the screen? I copied it the last firmware to the usb stick but nothing happend after the printer boot. I think need comfirm the install on the screen.
I have the same problem, even without rooting. This morning it still worked, and the afternoon it doesn’t. When starting up the machine , Creality is “waving” a moment and then you see a little glitch in the screen, and Creality is showed solid, and seems to be frozen. The rest of the machine works fine via Wifi. Maybe a temperature-based fault, because it’s hot since today. Hope someone knows an answer because changing filament the right way is only possible via the screen.
Sorry, forgot to mention that my machine is the Ender3 V3 XZcore
