Most likely I'm being stupid, but Longer LK4 Pro doesn't see the firmware file. I have tried the following file names:
firmware.hex
BOARD_LONGER_LGT_KIT_V1.hex
LONGER_LGT_KIT_V1.hex
LGT_KIT_V1.hex
The printer does not respond to the firmware file in any way, the USB flash drive is working, also formatted it
