No, you can brush anything as long as you turn it off. If it is G 17, I suggest you interpret it as official unlocking, and the machine is still s-on, but there is a red letter on it. If it is officially unlocked, it will become unlocked. Like the s-off effect, there is no need to make a gold card or something. Just open the brush. After brushing the package, decompress the brush package.
