Hi - first-time poster, somewhat-new rooter. I tried searching for this but didn't find anything (might not have searched very well), so here goes: After I upgraded to Froyo on my Moto Droid (Pete's FRG01B, Easyrooted), I ran into the Pandora issue everyone else noticed with AAC+ - the crappy sound quality. So I did a search on that, and found the "media.stagefright.enable-player=false" fix, and somehow managed to make that change in my build.prop - I was able to chmod 777 it and save the change. Next thing I know, my Quadrant Standard score (and yes, I saw the recent posts re: Quadrant Standard and spoofing the scores) drops from around 1100 to under 600. I figured I would go change build.prop back to determine if the StageFright setting was what was screwing up the benchmark, but the file is back to read-only now... and chmod 777 won't set it to read-write anymore, even if I sign in as su. Instead I just get the error "Unable to chmod build.prop: Read-only file system." So my question is, how can I get read/write permissions back to my build.prop file? What obvious thing am I missing? All help would be appreciated!
