CMahendra's Guide for LOW-SOUND VOLUME FIX for MT6589x Phones
[Useful for Porters]

This guide is for MT65XX rom porters, who want to increase volume of their ported custom roms.
Newbies with little RootExplorer experience can also read carefully all the steps and can increase volume of phone.

WARNING:
  1. This Information is Only for Rooted Phones and people with RootExplorer and flashing experience.
  2. Whoever it is porter or newbie, first take Nandroid Backup before proceeding. If fix does not work you can Restore back your Nandroid Backup.
  3. This is just one of the many methods. If the problem is in more than one places then this fix may not work for you.
  4. DO AT YOUR OWN RISK. I am not responsible for any brick or problems.


STEPS OF TUTORIAL FOR ROM PORTERS/DEVS

Step 1)
Download this Flashable zip file "Sound_Permission_Setup_CMahendra.zip" (attached below) and copy on your SDCARD. Also install RootExplorer.

Step 2)
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.

Step 3)
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.

Step 4)
With any Root Explorer on phone, copy this folder from root of yours phone to your SDCARD.

/data/nvram/APCFG/APRDCL

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.

Step 5)
Now flash/Restore your custom rom which have low volume problem.

Step 6)
Open RootExplorer and open "APRDCL" folder on your SDCARD and select and copy all following files mentioned below.
================================
Audio_AudEnh_Control_Opt
Audio_CompFlt
Audio_Effect
Audio_Hd_Record_Param
Audio_Hd_Record_Scene_Table
Audio_Sph
Audio_Wb_Sph
Audio_ver1_Vol_custom
Audio_Vol_custom
Audio_Wb_Sph
AUXADC
Headphone_CompFlt
HWMON_ACC
Sph_Dual_Mic
================================
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.



Step 7)
Now paste these files in following folder location of your phone.

/data/nvram/APCFG/APRDCL

The same folder location from where the files were copied from stock rom.

Step 8)
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!

EXPERIENCED PORTERS CAN MAKE THEIR OWN FLASHABLE ZIPS EASILY.

Hope this helps.
