If you want to be promoted, find a manager who has a track record of getting people promoted and transfer to them, then do the above. Many managers (and to be fair, environments and factors outside of their control) are awful in ways that boggle the mind, and no (sane) amount of effort will help you in that case.

The other method is to quit, if you are actually better than your level but your company fails to acknowledge it for whatever reason.
