Does anyone know how to downgrade the firm wear? Anyone have a link or know how? Also I have the LCD Programing card, thanks for the help! Happy holidays!
Did you download the USB Link software and install it? That's probably the easiest way to perform the downgrade. However, I'd check to see if you have compatible firmware already installed on the ESC. Unless the ESC was manufactured very recently, I'd bet you'd be using the old firmware.
Connect the ESC to the LCD box, and the LCD box to the PC using a USB cable. Open the USB Link on the PC, and click on "device" at the top of the screen. Select "ESC", then select "firmware upgrade" from the menu on the left. You should be able to find the firmware installed on the ESC from that screen. Post a reply once you know what firmware's installed, and we'll proceed from there.
