[HTC Desire X] atifjay:
Viper4android installation flash method for s-on HTC DESIRE X DUAL SIM T329W PROTODUG

If anyone Got viper4android fx or hifi (audio mod) by [MENTION=3901724]zhuhang[/MENTION] [MENTION=1569052]viper520[/MENTION]

But it won't work on your HTC phones due s-ON (/SYSTEM WRITE PROTECTION)

even if you are rooted.

For over nearly 2 months I have been trying various things 2 get viper audio fx to work on

HTC DESIRE x dual sim t329w protodug, ,,,,,,,,,

So, here I got it working after many searching$

Recommendations :

1. TWRP for htc protodug by [MENTION=4350492]neXus PRIME[/MENTION]

2. Download this below :

(necessary mod only for htc desire x dual sim t329w protodug)

https://www.dropbox.com/sh/egx2gpjxyl7a6bh/mda8Rr8jza

now you got the folder viPer audio for htc protodug, ,,

Note :- don't try on any other device

As the files are edited to work only on

htc desire x dual sim t329w protodug

Commands are edited under original/stock

build.prop and audio_effects.conf extracted from [[protodug]]

And only for those who are currently on

stock rooted HTC PROTODUG (T329W)

and/or running roms built by [MENTION=830797]ckpv5[/MENTION] for

Htc desire x dual sim t329w protodug

Follow these steps, ,,

1. Put the folder in sdcard where you can locate it easily, open the folder

INSTALL the viperfx.apk and viperhifi.apk both as a regular app.

2. Now boot into recovery,

3. First thing to do is --- creating a "NANDROID BACKUP"

(skip, if you already got NAND backup)

4. Now under MOUNT tab Ensure sdcard and system are mounted.

5. Get into ADVANCED tab

Click on FILE MANAGER --- scroll to sdcard and locate the folder viper audio for htc protodug.

open it and, (execute carefully !)

Click on build.prop and

copy the file and browse to /system and

click the select button on bottom right corner and then you will be asked 'swipe to confirm' then, swipe.

go back to viper folder on sdcard and now

click on audio_effects.conf

and copy the file and browse to /system/etc

and repeat the same swiping procedure for confirming copy,,,,

AND back 2 viper folder you will find these soundfx libs for viper audio,,,,

libv4a_fx_gb.so

libv4a_fx_ics.so

libv4a_xhifi_ics.so

You have to copy these each to /system/lib/soundfx

Done, ,,,,,,,

copying summary to confirm :-

-- build.prop to /system

-- audio_effects.conf to /system/etc

-- (libv4a_fx_gb.so , libv4a_fx_ics.so , libv4a_xhifi_ics.so) to /system/lib/soundfx

6. Now fixing permissions..........

Recheck whether system and sdcard are mounted,,,

get into advanced/file manager Select /system and click on build.prop ,,,,

you have to click on chmod(never click on chmod 755)!,,

There you will see default value 0000 ,,,

edit the value to 0644 and

press enter button on keyboard(qwerty).

And slide to confirm.

Now head to /system/etc ,,,

click on audio_effects.conf and select chmod ...

Enter the value 0644 Confirm by swiping.

After, go to /system/lib/soundfx

And fix permission via chmod entering value 0644

For each of the below, ,,,,,,,,

libv4a_fx_gb.so

libv4a_fx_ics.so

libv4a_xhifi_ics.so

Now reboot the system under REBOOT tab

Open, viper audio fx and hifi simultaneously, ,,,,,,,,,,,

Check the options tab for "driver status"

You will get :-

For viper4android/viper audio fx

Driver version - 2.3.2.2

Neon - enabled

For viper4android hifi

Driver version - 2.1.0.2

Then 100 % success.............

Congratulations

Turn off DVC under settings/audio/advanced tweaks if you want to use it

with poweramp

And try not to merge any other equalizer/mod wit these two (fx and hifi)

It will distort the quality.........
