STEPS OF TUTORIAL FOR ROM PORTERS/DEVS
Download this Flashable zip file "Sound_Permission_Setup_CMahendra.zip" (attached below) and copy on your SDCARD. Also install RootExplorer.
TAKE BACKUP: Take full nandroid backup of your low-volume custom rom in recovery mode, in case of any problem happens in the process, it will be useful.
Now you have to find and BACKUP copy of STRONG SOUND files from Working Stock Rom. So, Flash stock rom with full wipe and start phone and test sound volume, if ok or not.
With any Root Explorer on phone, copy this folder from root of yours phone to your SDCARD.
Copy paste this "APRDCL" folder on your SDCARD. There will be around 15 to 16 or more files inside. Now stock Sound file Backup is done.
Now flash/Restore your custom rom which have low volume problem.
Open RootExplorer and open "APRDCL" folder on your SDCARD and select and copy all following files mentioned below.
You can also include any file with words "speaker" or "sound" or "volume" or "Mic".
Do not worry if any file is missing.
***IMPORTANT: Do not copy or replace files starting with "Camera" and "File_Ver". Leave them as it is.
Now paste these files in following folder location of your phone.
The same folder location from where the files were copied from stock rom.
Now reboot the phone into recovery and flash this Sound_Permission_Setup_CMahendra.zip (attached below)
Restart and you are done. Now you may check the volume.
This worked perfect for many of my A116 MT6589 roms. The Volume in RingTone, Alarm, Music, etc, increased like hell. But if volume does not increased you still can Restore back your Nandroid Backup from Recovery. THIS IS MOST SAFEST WORKAROUND BECAUSE FILES ARE FROM YOUR OWN STOCK ROM. SO PALS, NOT TO WORRY!
Hope this helps.
Thanks to Internet. This is not my own work, I have collected this information some time back which was found on internet. So thought to keep it properly organized in one place. I don't remember the exact page but I saved the information in text file and now sharing all.
