There is no duplication there and you can put them in build.prop as well.Code:ro.ril.hsxpa=3 ro.ril.gprsclass=12 ro.ril.hep=1 ro.ril.enable.dtm=1 ro.ril.hsdpa.category=28 ro.ril.enable.a53=1 ro.ril.enable.3g.prefix=1 ro.ril.htcmaskw1.bitmask=4294967295 ro.ril.htcmaskw1=14449 ro.ril.hsupa.category=9
btw, once one of those prop settings is applied, it cannot be changed.
But I dunno if local.prop or build.prop is executed first.
I guess the only way to know is to give a parameter a setting in both prop files and see which one sticks.
The prop file that has the setting that sticks is the file that runs first.
