ender 3 pro firmware

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

So you took out your original board, put in a new one, that didn't work, put back the old one? There's no reason to flash firmware again then.

Does everything work if you leave the firmware file on the SD card?

Maybe something else, other than the controller board is broken, if both of your boards refuse to work?

when i put the sd card in with the firmware it loads i have all the operation. so i shut it down to take out the sd card and go to my computer and through my usb i connect it and delete the bin file. i load up a g code file on a now blank sd card and when i insert the sd card into the printer and turn on the power i am met with a blank screen as a note i have tried a few firmware files. they all look to load up fine

Well, just keep the firmware on the card then. Maybe something was changed with the boards that have GD chips, and they require the file all the time? No idea, sorry.

do you have a recommendation to what firmware is the correct one, i know creality site is very confusing and out dated. maybe github is a better option

"GD_Ender-3 Pro_HW_V4.2.2_SW_V2.0.8.2" from Creality's website is probably your best bet, if you don't want to manually build Marlin (https://www.creality.com/pages/download-ender-3-pro)
