Chitubox 1.9 and Creality LD-002H - "Invalid File Format" error

2021-7-26 8154

I just upgraded to Chitubox 1.9 and I'm getting "Invalid File Format" on my Creality LD-002H. I'm using the same USB drive as I previously have. The only thing that's changed is the new version of the software.

I reverted back to version 1.8.1 and it's working again, but this seems like a pretty bad bug.  I hope it gets fixed soon.

    There's a new firmware for the Creality LD-002H . 
    Download it from Creality site and install it and all go fine.

    Hi, if you get "Unknown File format" error message with file from CHITUBOX Basic V1.9.0 , please check if you have update the latest firmware.
    Check the new firmware here:
    The printer needs to upgrade the firmware to read the CTB files sliced by CHITUBOX Basic v1.9.0 and CHITUBOX Pro.

    Just had the same problem with a LD-002R, "upgrading" the machines firmware is not an option, what if after trying that it still doesnt work?  "please contact your supplier" will be the next  response

    I downloaded the firmware from the creality website where it indicated the version 443 that the chitubox requires, but even after installing the firmware, the printer still keeps the file not supported message. and in the system options and about, 4.3.16 appears, even though I'm installing 4.43 on the manufacturer's website.

    Obviously the firmware did not update properly. Reread the installation instructions and try again--if that fails contact Creality.

    What were the names of the update files? There should be at minimum one ".CTB" file (the actual firmware¹), and perhaps  a ".bin" file (bitmaps for the user interface²), and also perhaps an "update.LCD" fiile (the "boot logo"²).


    ¹ - The ".CTB" file is whai is supposed to autoload on a cold boot.

    ² - The ".bin"  and "update.LCD" files are "printed" after the cold boot.
