Ender 5 Pro firmware upgrade
Hello, I have the 1.1.5 board and 18.104.22.168 firmware. I downloaded the files to upgrade the firmware (Ender-5 pro 1.1.5 mainboard（8bit）.zip - https://www.creality.com/download). When I unzip, there are no .bin files and I thought the firmware would include them. How do I upgrade, or is my device already upgraded?
