I felt that way too at first, but then I just put the pertinent files in a folder on my extSDcard (I always stay with Samsung based ROMs), including a saved copy of the modded build.prop. That means all I have to do is remember to reset GW before I flash a new ROM. When new ROM is flashed it's a cinch to reinstall GW![COLOR="Silver"]
so if i understand this i guess you would rename the build.prop file to .bak then copy and paste
the modded file on the extsd into the system folder then run the wallet setup and eventually
restore the original build.prop ?
