I have downloaded and installed CR4CU220812S11_ota_img_V2.3.5.34.img on my K1 printer. Now, I am unable to print due to notifications about missing filament. I have tried to change a name of monochrome firmwares to CR4CU220812S11_ota_img_V2.3.5.35.img CR4CU220812S11_ota_img_V3.3.5.34.img but at some point the upgrate returns an error.
My printer is unusable. Any solutions?
I hope this helps
No, It doesn’t. I have tried to install previous versions of the firmware. Each time I’ve got a message “…. installation failure”. I tried as well a name change, to increment it’s sem version number, to trigger an install process, but without success. Exampel: CR4CU220812S11_ota_img_V2.3.5.34 → CR4CU220812S11_ota_img_V2.3.5.35
CR4CU220812S11_ota_img_V1.2.9.12 → CR4CU220812S11_ota_img_V2.3.5.35
Dang ok. Let me check somewhere else
