Thanks for this. Is it cheaper to do this or to take it to a shop?

Don’t know. You’d have to ask your LBS as I suspect prices vary a lot between shops. But given the hourly rate for servicing isn’t cheap, for anything more than possibly a one-time firmware update, I suspect doing it yourself is cheaper.
