We have just discussed about different possibilities for installing a custom ROM firmware on your Google Nexus 5, but updating or downgrading with official or stock 4.4.2 (or any other Android firmware on that matter) Android OS is the ideal solution if you don’t want to assume any major risks.
Each time, the manufacturer works on offering us better and better software experiences through their tested official software releases, so what do you think? Is this what you are looking for?
