Hi!
I want to mix two flashing types for device : fastboot and custom ( run custom script )
I already did both types separately using deploy methods : fastboot and flasher
How I can mix both types?

And in web gui in device panel what does mean that error?
Configuration Error: missing or invalid template.

Jobs requesting this device type (mix-type) will not be able to start until a template is available on the master.

Best regards, 
Ilya
