hi,
can't get firmware installed printer currently lies dead...
i have ender 3 pro, 1.1.5 main board, bltouch 3.1
i bought bltouch as kit from creality so i have their usbisp. i dont have an arduino
i installed com com drivers (ftpd or whatever it was?!) and usb conection to printer yields USB SERIAL CH340 (COM3) in device manager
(following https://medium.com/@jethro_20307/creality-ender-3-pro-bltouch-v3-1-marl…)
i connected the supplied usbisp to mainboard and used progisp to flash optiboot_atmega1284p from https://github.com/Lauszus/Sanguino/archive/master.zip
then i used usbisp to flash https://www.danbp.org/downloads/Marlin-1.1.9.1+Fix_HEX_TMC2208.zip
rebooted and printer screen was blank...
