You are supposed to go to the upgrade tab and use whatever fw from the manufacturer you want... It is written
in the documentation that when you uninstall it puts something that doesn't hash but is unlocked.
You just got lucky that the S17 and the S17 Pro are the exact same thing, but normally the miner would have not hashed at all waiting for you for the next step.
Since you didn't use the support thread, you got a late response. I made the
support thread for a reason. Worse, you didn't even mention Braiins OS in the thread title.
