is this the correct firmware ?

yes
Motherboard firmware: A30_M07_V0_01.bin

LCD screen firmware: A30_S02_V0_01.bin

what i see is
motherboard firmware is A30_M07_V2_01.bin
lcd firmware is A30_S02_V2_01.bin
is this is the same V0 and V2 ?

yes

when i burn the motherboard and lcd firmware a new sd card must be in the external slot of control box or not ?
and when i refresh the lcd UI, i must insert another sd card with lcd UI in lcd slot ?
thank you very much my friend

Hi,when the firmware is burned, the SD card does not need to be inserted.
To update the UI, you need to put the file into the SD card, and then insert the SD card into the card slot of the machine

Hi,
To UI update, the sd card with UI in, must be insered in the machine or lcd sd slot ?

Hi
i udpate the firmware of mainboard then lcd successfully. the lcd screen still black.the 2 leds on the back of lcd is light on.
i copied the UI on sd card then insered in the lcd slot. nothing heppened, the screen still black.
i can't see if the lcd screen downloaded because it's black
what can i do ?
thanks

Hi,the firmware did not update successfully.
You need to copy the file（A30_M07_V2_01） to the desktop and then drag it into the firmware burning tool.
Direct drag may cause file recognition errors.
