インストールに際して、Busyboxの導入が必須となります。
shellからでも設置は可能ですが、root explorer等のアプリがあると大抵の人は楽かなと思います。
簡単な意訳
ここからzipファイルを落としてきてね。
そのファイルを解凍したら中に、
ViPER4Android_FX_v2505_A4.x-A7.x.apk
ViPER4Android_FX_v2505_A7.x_Nougat_IO_test_fix.apk
の2つが入っているけど今回使うのはViPER4Android_FX_v2505_A7.x_Nougat_IO_test_fix.apkだよ。
そのファイルを設置する前には/vendor/etc/audio_effects.confのバックアップを取っといた方がいいよ。削除してもいいけどもし必要になったらあれだからね。
バックアップができたら、ViPER4Android_FX_v2505_A7.x_Nougat_IO_test_fix.apkを/system/priv-appにコピーしてね。
そしてパーミッションを-rw-r–r–(644)に設定してね。
再起動してViPER4Androidを起動してドライバをインストールしてね。

Now that you have everything setup correctly, download the official ViPER4Android for Nougat (FX 2.5.0.5): Link
Extract the downloaded zip and it will contain two apks –
ViPER4Android_FX_v2505_A4.x-A7.x.apk
ViPER4Android_FX_v2505_A7.x_Nougat_IO_test_fix.apk
Since we are going to install V4A on Nougat, we will just need the “ViPER4Android_FX_v2505_A7.x_Nougat_IO_test_fix.apk” file.
If you have downloaded it to your PC instead, just transfer the apk to your phone’s storage.
Before we head to the installation, open the root file explorer and grant it root permissions when prompted. Navigate the root/system storage and go to “/vendor/etc”.
You shall see a file named “audio_effects.conf”. Rename that file to “audio_effects.conf.bak“. While you can simply delete the file, but we prefer renaming and keeping it, if we require it in future.
Open root file manage and browse to the location where the apk is present. Copy the . “ViPER4Android_FX_v2505_A7.x_Nougat_IO_test_fix.apk” file and move it to /system/priv-app.
We are not done yet. Long-press the file, tap on the 3-dot overflow button, and select Properties. Go to the ATTRIBUTES tab, set its permission to -rw-r–r–, and select APPLY.
Reboot your device now.
Now go to the app drawer and run the ViPER4Android FX app. When you are asked for storage permissions, make sure to grant them.
A prompt will display for driver installation. Select Yes to confirm the driver installation process. You will also need to allow Superuser permissions to the app.
Your phone’s screen may freeze, don’t worry just wait and do not exit the app. When the installation is successful, you will get a message. Tap OK and reboot your device.
