[CUBEMARS] AK60-6 doesn't connect with MCP2515-Arduino set up

Hi, I have to work with a AK60-6 KV140 V1.1 and control it using a CAN module for Arduino. It connected but didn’t move when I tried sending a command to it, so I looked around and tried flashing the firmware using this guide but now the motor doesn’t connect to the CAN module and doesn’t let me calibrate the MIT mode. Does anybody know what code for the arduino I have to use to do the connection or if I should use another firmware to flash my motor?
