Brand New Board and Can't get firmware

[RickzFPV]

I just got a MKS Robin Nano V3.1 and TS 35 screen installed, and now I essentially Can't use it because I can't build Firmware for it I have tried and tried. figured out it is a mismatch on the versions. firmware is 02000905 and latest version makerbase has listed is 02000902. I really don't know what to do from here been on discord and it is so frustrating, those guys over there think you should be a programmer or something. I just wanted to upgrade the board because the old board had a bad Z axis stepper Driver. Can someone please help me or guide me a little as what I can do to update the firmware, I have tried doing it in marlin and with the mks tool and neither one has been a success.

Have you flashed the bootloader files from github? If you did, that may be why you cannot flash FW now. You can try using an usb stick instead of my sdcard (worked in my case since I flashed the no-beep bootloader).

If all else fails, you can try the SWD port: #81 (comment)
