@mmarlette I have tried to replicate your issue, but cannot no matter what I try. Just to be certain, you get the error when you go to the device in the IDE and try to change the device type it is using from the Philio to the Generic, right? Once you hit update the error is thrown?
The only thing I can think of is if it it wasn’t copied and pasted correctly. There really aren’t that many differences between the generic and the Philio at this point. Just an easier way to update the parameters. Try the raw link for easier copying and pasting:
