How I passed safetynet, got root, adblock and viper-fx to work on OOS 4.0.2 OP3T

I decided to start this thread for a couple of reasons 1 so I can remember what order I did things in to get back after a wipe and 2 so maybe it can help others to setup certain apps how they want and not have to spend the time I did searching and googling.
To start we are going to assume you already have an unlocked bootloader and TWRP installed.
After a fresh wipe I flashed OOS 4.0.2 Full from this thread in TWRP
https://forum.xda-developers.com/oneplus-3t/how-to/rom-oos4-0-nougat-op3t-leaked-t3523482
I recommend a fresh wipe because every time I did a dirty flash or restored a backup my Android System started draining battery like crazy and phone would get warm while charging
Without rebooting I then flashed Magisk V10.2 in TWRP
https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
Still without rebooting I flashed Franco Kernel in TWRP
https://forum.xda-developers.com/on...ernel-franco-kernel-r1-28th-november-t3508904
I then wiped dalvik and cache and rebooted phone.
edit - THIS STEP WILL NOT WORK ON 4.0.3. It has been patched out.
Somewhere in the process my DM-Verity was tripped and although annoying it does not seem to matter and it can be fixed later by following this
https://forum.xda-developers.com/oneplus-3/how-to/fix-easy-method-removing-dm-verity-t3544339
After phone booted and I setup account and wifi and I go the play store and install PHH superuser
https://play.google.com/store/apps/details?id=me.phh.superuser&hl=en
Once installed I open it and click the 3 dots and go to settings
Where it says Superuser access I toggle between Apps only and Apps and ADB till I get the message Superuser granted to Superuser
I then go back into play store and install Magisk manager
https://play.google.com/store/apps/details?id=com.topjohnwu.magisk&hl=en
I go into Magisk Settings and click the checkbox to Enable Magisk Hide.
I then reboot phone
Once phone reboots I open Magisk manager again and check safetynet. It now passes.
I hate ads, I had been using Adaway from F-Droid with MM but I couldn't get it to work on N
I found this https://github.com/AdAway/AdAway/issues/770 after many searches. About halfway down a user named KreAch3R has comiled Sanjay900's changes into an apk so I figured I would give it a try.
At first I could not get it to activate and block ads
I installed this busybox and then it activates no problems and now most ads (not youtube) are blocked
https://play.google.com/store/apps/details?id=stericson.busybox&hl=en
Now what I really wanted was Viper4arise. I tried flashing some in TWRP and I couldn't get them to work and this led to a couple more wipes. But I really wanted this so I kept searching.
I found this https://forum.xda-developers.com/apps/magisk/viperfx-mkm-magisk-t3535401
I downloaded it and enabled it in Magisk manager
Still no luck and I couldn't get it to work.
After more googling and reading through the other threads for viper I figured it was deep buffering
I used ES file explorer as I was not at home and went into system/etc and found audio_policy.conf
I commented out the first line I saw that said deep_buffer.
After saving I rebooted and now Viper-fx works
To get it to work with Poweramp I had to set FX compatibility mode in Viper to compatible and in Poweramp audio/advanced tweaks I had to disable Direct Volume Control and Enable MusicFX.

Thanks for sharing

Did you have any special trick to get viper to work ? Tried commenting out the line deep_buffer and still unable to get viper to work.

The only steps I did are what was listed.
I was able to replicate it twice after wipes with same steps.
This is the line I commented out in attached

Edited: Didn't see the attachment earlier. Answered my question. Thank you btw for sharing this the rest of the steps worked great for me. I am passing safety net.

Ya I realized a SS might help more so I edited it in.

Would you be able to send me that file ? I am just curious what is wrong with my setup.

Just want to say thank you again. Didn't see the PM until now. I was able to use another guide on XDA to get Viper working.

Viper will not work on all apps at any time on OOS 4.0.2. Enable Compatibility mode in settings to get it to work. IMO this produces lower quality audio, but it works.

Still cant get viper working. Nothing of deep_buffer is commanded. Please can you share your audio_policy.conf?

You need to edit in a # on the deep_buffer line.

1) With what app?
2) Did you enable Viper's Compatibility mode?
3) I've also modified audio_policy_configuration.xml to remove deep buffer. Messing with this file too much will break your audio though.

WHat app isn't Viper working with? Viper processes audio on a per-app basis, based on the audio buffer the app uses. Google Play Music, on Nougat, does not pipe through Viper even with modifications to the audio config.
Enable compatibility mode. At the moment this is the only way to get the highest compatibility with apps- like Google Play Music.

It's now working after disabling audio buffer. I use most of the times Spotify to listen to music

I followed same steps earlier. But my selinux is enforcing. I have to set it to permissive everytime on reboot. Permissive fix that comes with arise didnt work for me. Any idea..?

Do you think the Elemental X Kernel would be ok instead of franco kernel? Not sure if I'd get compatibility issues with any of this stuff. Btw not going to try to get adblock or viper fx. Also, do you wipe the system or just what TWRP has already checked?

Not sure. I know it all worked the same with stock kernel.
Normally when I need to wipe my phone it is because I have really messed it up so I wipe system and data.

How do I install viper

I have tried installing the apk but everytime I install the driver and reboot it asks me to do it again.
I have tried renaming audio_conf but still not luck.
How do I go about install viper to 7.1.2 without it failing

Search for VIPER4Android_2.5.0.5_guitardedhero.zip,
flash the zip with twrp, reboot your device, use a root explorer and under vendor/etc rename the audio_effects.conf to audio_effects.conf.bak for example.
Start the viper app, apply the driver install, be patient, after install reboot your device, viper works now even with selinux enforced. The viper app will be installed with the zip, no need to download it anywhere else.
Here on XDA you will find threads about viper and arise from guitardedhero.

This solution is indeed reposted everywhere but did not work for me.
What worked was a clean install of my ROM ( lineageOS 14.1 20170619 nightly) , Kernel (Franco v52), and SuperSU (v2.79) (Magisk somehow messes everything up). Then I flashed ARISE with one of the older .zip (2.94 should work, I don't know which version I used since I renamed it back in march).
In AROMA I chose "jedi" -> viper 2.3.4.0, since only the older Version works and "remove deep buffer"
after the installation I rebooted, changed the name of
/vendor/etc/audio_effects.conf
and installed busybox to
/system/bin
so viper would find it. If you don't do that, viper will try and fail to install the driver, complaining busybox is not installed. The driver is already installed by the ARISE.zip so you can reboot.
After turning off "AudioFX" Viper worked as desired (including streaming audio, that's what "remove deep buffer" is for).

Yes, that's what I usually use too (2.94), but he was only asking for viper, and the solution i posted does work. I'm actually using it this way with paranoid and have no issues. I use viper with every rom and I always delete AudioFX, musicfx and remove deep buffering, but I don't install extra busybox on los based roms.

The guitardedhero.zip did not work for me, as to why I don't know. Magisk also has several modules that should enable Viper4Android which seem to function for the wast majority of (angler) users. Maybe the installation of busybox is unnecessary, I did not check because I dreaded one more reboot after hours of tinkering. If there is an obvious culprit that hinders an "easy" installation of Viper4Android, I'd be quite interested. I'm struggling with that guitardedhero.zip solution since i upgraded to 7.x. (throughout stock and LineageOS and all bootloader/radio/vendor versions).

The n7 runs with los.
Usually I use arise with my tablet for enjoying dolby too.
Edit: with Los only permissive, but it's working

[GUIDE] Ultimate audio and battery guide

Comprehensive audio guide for android 8.1 and P DP1 (saves battery)
Cyan means 8.1 ONLY​For android P only, flash the magisk modules in TWRP, manager is broken with module flashing, just a temp patch from @topjohnwu​
I am not responsible if you break, blow up, or destroy your device in any way​
Hi XDA, this is the comprehensive guide to making the google pixel and XL have the ultimate audio mods installed while saving battery (if xposed is what you're looking for, it's under amplify)
Prerequisites
TWRP 3.2.1-x
Magisk v15.x REQUIRED
busybox (osm0sis) installed (for some mods)
Link to homeboy76's guide, look at step 9 or 10
Magisk permissive module Download
Dual stereo speakers Magisk module by kingbri(me) (AML bug fixed)
I ported Chdloc's mod into a magisk module, need to add it to the official repo, but it works very well right now
Download the zip file from this thread https://forum.xda-developers.com/pixel-xl/development/magisk-module-pixel-stereo-speakers-t3753190
Make sure you have permissive installed (check prereqs)
Flash it in Magisk
Reboot
Profit
Atmos
Download dolby unity port by @Zackptg5
Install (Universal)
Flash the permissive script in magisk
Flash the dolby zip in Magisk, It's a module
Reboot
App should be installed
IF installing with V4A, install Atmos, reboot, then V4A, then audio modification library, reboot. Everything should work
V4A steps
Install Ahiron and zackptg 5's v4a module (follow the prompts during installation)
You're done!
Ainur Sauron mod- fixes audio quality by importing qualcomm drivers as opposed to the stock android ones
Open magisk manager and navigate to downloads

Fwiw, I used this with Magisk 15.2 in a clean install of 8.1. Working without issue

It doesn't actually give you dual speakers though? My understanding is that one side is a speaker and the other is a microphone.

First of all are you on aml viper? ARISE doesn't work with 8.1 and i'm talking to some of the devs about fixing this issue. I've had some experience with LOS, it may be throwing an error because of the rom or because there are some other things LOS has by default that is interfering with viper. The builds are unstable, my advice would be to switch to crDroid because it is LOS based, but is made for audio. I'm not sure what you mean by prompts but I have been hitting the vol up key both times and it works for me on the Pixel Dust rom

I changed the v4a guide, you don't need the permissive module, maybe that's what's crashing it?

It didn't "crash" per se, it just wouldn't install the necessary driver after the package was installed. I'll try it with the module disabled and see if it works. Do I still need the permissive module for the other mods? Or just when they're being installed?

Viper4Android on the Redmi Note 7

Hello there, I've been trying to get the viper4android but it just keep asking me to install the driver.
I've tried with the magisk module and the xda labs version (which looks awesome btw).
I'm on magisk 19.0
My rom is xiaomi.eu 10.4
Any ideas?

Just install a Magisk module or a script to set SeLinux as Permissive. I am using it right now and everything works great.

I've had trouble installing it, too. Tried every rom posted on this forum, stock MIUI, and some GSI, and in none of them I could get V4A working. Used Magisk Module, too.
Could you please ellaborate how you installed it? Which rom? Which Magisk/V4A version?
Viper is literally the only thing I'm missing from my previous phone; I'd reeeally like to enjoy it again!

Yes, I tried that one as well. Always the same error: "No driver installed", press yes, restart phone, and back to "no driver installed" again.
Which busybox version are you using?

Ok, I finally got it.
I'll write it here for anyone with the same problem, or for future reference.
First, check that you have BusyBox installed.
Then, in Magisk Manager, install the Audio Modification Library. Reboot.
In Magisk Manager again, install the Viper4Android module. Install options: new driver, old interface, user app, library workaround no, oneplus 3 workaround yes. Reboot.
Check opening the app, it should work normally, with no "driver not found" errors.
Notes: tried with letsmakecake's Lineage 16. People in the RN7 Telegram group recommend busybox.zip, but I confirm that the stericson app works the same.
If anyone has problems making it work with Poweramp: settings->audio->advanced->
- Direct Volume Control: disabled
- MusicFX: enabled
Then go to the eq screen, second tab, press MusicFX so it's enabled.
Thanks all who helped, and the V4A devs. This is the best audio tweak mod available for Android, hands down.
Personal recommendation: try the Dolby Pro Logic II irs in the convolver!

Alright, can confirm this works, with some minor differences:
-new interface (just personal preference)
-library workaround was applied automatically
I also have selinux permissive and MusicFX disabled (app frozen).
The package I used is Viper4Android FX Legacy. The new version, Viper4Android 2.7, did not work for me.
My ROM is HavocOS.

Question about Viper

I use Amazon Music with Viper Mod and Dolby. The problem I have is when I start playing my music I have to go into the Viper app. As soon as I open the app Viper kicks in.
Is there something I can do to kick Viper in automatically?

Hi, re-instak and follow instructions, instal as system app, u mess a step

Honeslty, I have never been able to get Viper working fully on my 6t. You might want to try removing the optimization in settings to see if that will let the app continue running. I think OOS just disables it after you don't have anything playing for a while.

I mainly play on my car Bluetooth when I am driving mostly a volume issue but do like surround sound as well

Have you tried making Viper a system app so that the process won't continually get killed?

Viper4Android FX 2.7.1.0 doesn't give me a option to select anything, It just installs completely and then says to reboot. I downloaded App Systemizer (Terminal Emulator} and moved it to system and now you are right it is running fantastic.

As a follow-up, about a day after I had posted, my viper stopped working. So I deleted the plug-in in magisk, and reinstalled 2.7.1.0 fresh and it's been work ever since! I apologise if I came off flippant at all. Seems they changed / updated something and that had to be done.

No need to apologize after a few times of uninstall and reinstall I gave up. Between my Bose Stereo settings in my car and the phone settings I get really good sound so I'm good.
