If you would like to run a non-official (i.e. experimental, unstable) build on a Mass-Production/G1G1 machine you will need to acquire a [[Activation and Developer Keys|developer key]] to allow your (locked) laptop to load the unsigned image. You probably ''do not'' need to run an experimental image for most activity development purposes. | If you would like to run a non-official (i.e. experimental, unstable) build on a Mass-Production/G1G1 machine you will need to acquire a [[Activation and Developer Keys|developer key]] to allow your (locked) laptop to load the unsigned image.
