Audio Hack for Samsung Galaxy (test phase before included in Galaxo)
A user from AndroidForums, balu_radu, found a way to change audio gain settings.
BE CARREFULL ! DANGEROUS SETTINGS ! YOU CAN BREAK YOU PHONE !
- Download
http://www.drakaz.com/FILES/TMP/servicemodeapp.zip and
http://www.drakaz.com/FILES/TMP/AudioFilter.txt
Extract servicemodeapp.zip in /data/app_s :
adb remount
adb push serviceModeApp.odex /system/framework/
adb push serviceModeApp.apk /system/framework/
- Push original AudioFilter.txt (prevent conflit with modified AudioFilter.txt and servicemodeapp tests) :
adb remount
adb push AudioFilter.txt /etc/
Then, reboot, and let’s try some settings !
headset music volume hack :
dial *#*#197328640#*#*, [8] audio -> [2] headset -> [2] rx value -> [5] rx codec for midi -> [1] rx codec gain, enter 5FFF for 4db, 7FFF for 6db, FFFF for 12db, 2014 for default
