[Solved] Flashing Firmware: ERROR! Something goes wrong. Try again

Hello, I am using Rosbot 2R. It flashed the firmware and the robot could move last time, but when I try again, it doesn’t flash the firmware and an error occurs, and the robot doesn’t move. The weird thing is the L1 part is blinking continuously, even though it is fully charged. Any help would be appreciated. Here is the error:

Hello @yongyun_song,
Please try flashing based on the latest image:

# Stop and remove all docker process
docker stop $(docker ps -a -q) 
docker rm $(docker ps -a -q)
# Flash firmware
docker run --rm -it --privileged husarion/rosbot:humble-0.13.1-20240201\
        ros2 run rosbot_utils flash_firmware

After this command, you should also be able to flash older version of firmware.
Let me know about results.
