I just flashed new firmware and bootloader following you guide. Big thumbs up super easy to follow rather than creality's own support.
However I did the bootloader and the flash, and when i turned on the printer today my screen is blank?
Blank screen means you need to flash the firmware. Are you on the stock board/lcd?
yes Stock board V1.1.3 with stock LCD
i did get it flashed on there because the first time i did it, i Saw your logo, and the screen as shown in your guide, but did not send m502, and m500 and now it is a blank screen, tried to reupload the bootloader and reflash the firmware with No luck
I would reseat all the connections to the LCD and check that nothing is shorted out.
I checked that, but to no help everything was fine
If you try to re-flash the bootloader and then load the firmware does it upload over USB?
