I have managed to get DSP Manager working FULLY on pretty much any ROM, Phone speaker volume ( not just ringer music to ), Headset,and Bluetooth. NOTE: The only music player it works with is power amp which is free and can be downloaded below ( don't use the one from the market ). it doesn't work on any stock music player such as Google play music, or miui music player that I know of. Changelog: Update 3: . Fix the force close issue some people have been having .Try to modify lib jumper.so from zte blade so dsp is fully compatible ( besides power amp ) with the warp Update 2: . Updated the install script . Under the hood tweak Power amp link: Go to play store. Or you can do it the way I did ( I didn't actually flash it in recovery ) 1. Open a root file manager app ( I use root explorer ) 2. Extract the zip you downloaded 3. Go to system/lib/soundfx 4. Delete all those contents this won't cause any force closes. 5. Now place all the lib.so's from the extracted .zip you downloaded to into the system/lib/soundfx directory 6. Now change all the libs permissions to rw-r-r ( The same permissions an app receives in system/app ) 7. Now place the dsp manager .apk from the extracted folder in system/app and give it permissions rw-r-r. 8. Go to the root directory where all directorys are located such as /data , /system and mount r/o 9. Reboot and enjoy dsp manager, Again it only works with power amp. Leave feedback and hit that thanks button if I've helped.
