When the LCD Programming Box, is "not" compatible with an ESC it only has one error to show and it is "Upgrade Firmware Required". Many users try to update the box, or the ESC and it either does not help, or, there is no update available. This is normal and simply means the ESC you are using, is "NOT" compatible with the LCD Programmer box you are using.
Many ESC's in the Quicrun, Fly Fun, Sky Fly, and Sea King do "not" work with the LCD Program box.
