after 3 days I'm getting desperate. i have an ender 3 pro with the 4.2.2 board and the chip is marked as gd. i have been trying to install firmware nor sure which one. ever time i get success I'm told to delete the bin file. when i insert the sd card (tf) with a gcode on it. i am met with the blue screen. do i need all the other files on the ender 3 sd card to have a directory
