Cant flash firmware into Creality 1.1.5 mainboard

Hi,

I got and ender 3 pro that shipped with the creality mainboard 1.1.4 with marlin 1.1.6.2, since the stepper motors were loud i bought the creality mainboard 1.1.5 that camed with the marlin 1.1.8.
I wanted the mesh bed leveling so i instaled arduino 1.8.13 IDE, downloaded the marlin 1.1.9.1 and flashed the firmware.
Everything working fine but the fan cooling the mainboard did not start when the stepper motors started, so i tryed to make them on by changing this configuration_adv.h line on the firmware:


//#define USE_CONTROLLER_FAN
#if ENABLED(USE_CONTROLLER_FAN)
//#define CONTROLLER_FAN_PIN -1 // Set a custom pin for the controller fan
#define CONTROLLERFAN_SECS 60 // Duration in seconds for the fan to run after all motors are disabled
#define CONTROLLERFAN_SPEED 255 // 255 == full speed
#endif


I took out the // from the first and third line.

Since then when i turn on my printer i get a blue screen and i cant upload firmware anymore, the message i get is this:

avrdude done. Thank you.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.


So i downloaded the marlin 1.1.8 stock firmware for the 1.1.5 mainboard from creality :

Ender-3 ProMarlin1.1.8EnglishTMC22081284PBootloader.hex

I did this so i can revert all the changes but i cant seem to flash automatically with the SD card.
I placed this file in the SD card root and when i boot the printer i keep on getting a blue screen.

How can i fix this?

Thanks.
