Hello. Thank you for such fast answer. Im have found a prebuilt early, but in guidelines it is called an UPDATE and flash thru mainboard SD Card port. Im tried to flash it from 0x0 address but have no luck with that. So im conclude what it is an update only binary.
PS I dont need to make changes. Im just have a try with different WiFi firmware (ESP3D) and now want to go back to MKS WiFi default one.
That's different from what I've seen. There's a downloadable application for the Makerbase controller I have that will reflash the board with their binary. I just used it once after reprogramming with my code and deciding to switch back to theirs..
If following their instructions for the SD card doesn't work, I'd suggest contacting them on their Discord to ask for help.
