@SpencerSpinn Hi
I've had the same problem and I finally figured out what was wrong. Somehow the SD card got corrupted and the firmware on the main board and on the screen also got corrupted. I tried to update the firmware with CURA and it didn't work. So I used Creality's Slicer to upgrade the firmware on my CP-01 mainboard & it Worked. I also upgraded the screens firmware through the microSD card slot on the screen with the .hex firmware file. The screen updated no problem but I still had the boot screen and nothing else until l upgraded the firmware on the mainboard through Creality's Slicer. My CP-01 is up & running again. I hope this helps.
