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

[William]

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 ?

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 ?

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.
