A simple CM 10.1 JB 4.2.2 Volume MOD
Simple way to increase your volume.
Im pretty sure you won't brick your phone but please do this at own risk I take no responsibility for your actions.
Make sure you are on a rooted device lol how else would you have 4.2.2.
Download the file
If file name is to3g.txt rename it to to3g
Copy file with a file manager ( I use ES with root permission)
Go to /system/ect/sound
Delete the file called to3g
And click paste and the new one should by magic appear.
Change permissions (hold you finger on the file) to rw r- r- ( mine looks like this rw r--r--
And then delete the new file to3g.bak if it appeared. If It didn't then you should still be OK so long as you did all steps.
Reboot and hey your phones louder.
Get noozxoide Eizo rewire pro and you have a loud kick ass phone again.
