I have a Sprint Note 2 flashed to Boost mobile, how can I get it back on Sprint?

[Cap Dee]

ok so kind of a noob here. but was wondering is there a way to get my sprint note 2 (that's currently flashed to boost mobile) back on the sprint network? Being that boost mobile now allows the sprint note 2 on their network i really want my 4g. also by reverting back to sprint will their be any quality differences?
