g9300 roms?

hey!I got a sm-g9300 from china and got my gapps to work and everything,but after rooting the device i still have some issues with the front camera(the pictures i take come out messed up) and i can't play most of the videos i record + my phone has become pretty unstable (can't use custom lauchers,keyboards,google now etc.)
there aren't any roms for the sm-g9300 but i was wondering if i could flash a sm-g930f rom...would there be any issues?
