My F77 is sending the wrong keypresses. This is independent of what firmware I have installed on there. I have the split shift, regular (long) backspace. The presses are in the correct general area, usually off by 1-2 keys. I have tried unplugging other USB devices, made sure my F77 is connected directly to the motherboard.
These wrong keypresses can be seen on pandrew’s utility. I select the correct layout, every key registers a press, it’s just the wrong key.
Okay, loading a default QMK hex file from the provided folder seems to work. But so far, the Configurator hex files don’t work. Loading the default QMK files in Configurator and compiling them, that also doesn’t work.
