[Q] Double tap to wake for KFHD7 [tate]

I'm using the Kindle Fire HD 7" with CM11 and I'd like to know how I could use double tap to wake on my tablet. I know it has something to do with the kernel, but I don't know which kernel to flash (and I've never flashed one before either).
A few more details:
I'm using the latest CM11 nightly from the official site
I rooted my Kindle using the guide at http://forum.xda-developers.com/showthread.php?t=2271909
I'm using TWRP recovery (2.7.0.0)
I haven't made too many mods outside of using a few Xposed modules (App settings, Greenify, Notification Mod, and Tinted Status Bar)
I hope I can get help with this, and thank you for any support you can give me.:good:

[HOW-TO] Installing Viper4Android (V4A) Audio on a Lollipop Tab S [Updated May 12th]

UPDATED: Updated V4A flash file to Viper4Android v2.4.0.1 and added notes about the TabS AOSP Marshmallow custom ROM compatibility by Schischu.
The obligatory warning:
"I take no responsibility for what happens to your device if you follow this guide. This procedure works with multiple Audio/Video apps. It should work for any Samsung device, but I can't confirm, so feedback please if it works for your device."
- 3DSammy
Root with SuperSU is required either using a standard rooting method that trips KNOX or following this guide "[GUIDE] How to root without tripping knox - Kitkat and Lollipop, Locked bootloader" by ashyx. Having SuperSU installed and functioning is essential to get around Viper4Android's need for SELinux permissive mode which is not possible when you are using the Samsung stock firmware.
As of June 8th maximumentropy posted a method to use SuperSU to work around Viper4Android's need for SELinux permissive mode. This requirement was problematic on Samsung devices where the SELinux mode changer app did not work with the Samsung stock firmware.
The instructions and flash files below will allow both custom ROM and rooted stock ROM devices to install Viper4Android, an amazing audio replacement.
Note: V4A and the included flash file works with the AOSP Marshmallow custom ROM compatibility by Schischu. Any of the SoundAlive comments below can be ignored for this custom ROM.
Steps:
1) Download the two flash files "ViPER4Android-supolicy.zip" and "LolliViPER_TAB_S.zip" (at the bottom of this post)
2) Flash ViPER4Android-supolicy.zip and LolliViPER_TAB_S.zip with FlashFire or a Custom Recovery (e.g. TWRP) of your choice.
3) If you want Spotify to work and maybe other audio/video apps then Samsung's "SoundAlive" must be removed or disabled. Options:
Backup then freeze or delete "SoundAlive 2.0" with Titanium Backup
Backup then delete the "/system/priv-app/SoundAlive_Tablet_20" directory with a File Manager that has RW "/system" privileges
Remove "SoundAlive" with an app like "System Remover app" found on the Playstore
4) Reboot your device and then start Viper4AndroidFX and install its drivers when prompted then reboot once more
5) Start the Viper4AndroidFX app and configure audio for the device speakers/headset/bluetooth as desired. Please refer to Viper4Android XDA forum for details about the extensive options.
NOTES:
Be aware that if you do not disable/remove SoundAlive then Spotify will disable V4A until the next device reboot. Causing confusion about whether V4A is actually working reliably. Other audio apps may also demonstrate this tendency.
If you check the V4A driver status and audio is not playing the status will show "Processing: No" that should change to "Yes" when audio is playing and V4A is working correctly.
A Rule-of-Thumb with V4A is to make sure to turn off any Audio/Video player app's specific equalizers, gain controls, audio effects, ... etc, as they interfere with Viper4Android. If you still cannot get Viper4Android working with a specific app, that's not listed in this thread, then search first then if necessary ask on the V4A's XDA forum.
So far the following Audio/Video apps have been successfully tested with V4A:
Neutron audio player (Settings and uncheck Equalizer;Sound Sound;DSP-Effects->Surround Sound;Relay Gain;Normalization)
MX Player Pro (Settings->Audio->Volume Boost unchecked)
Spotify (If it is working properly the Spotify->Settings->Equalizer will directly display the V4A app)
TuneIn Radio
Google Music Player
PowerAmp (PowerAmp Settings->Advanced->Uncheck everything)
YouTube
ViralPro (a YouTube alternative)
Apps that do not work with V4A (likely due to the removal of "SoundAlive"):
Samsung's "Music" app (still plays audio but not by utilizing V4A processing)
Please post any apps not mentioned here, which you either get working or that have problems with after checking the V4A XDA forum.
If you have SuperSU working and have never tried V4A do so and you ears with thank you!

Hi and thanks a lot for helping others out with the notoriously difficult to install viper app.
I presume the supolicy zip is intended as an alternative to setting selinux permissive. Any negatives to using one method over the other?
Also, can you please explain what your application zip does exactly. Does it just install the original viper as a system application or did you make any other modifications?
Thanks!

Either method of getting V4A permissive mode will work but if you rooted and maintained KNOX the stock bootloader blocks SELinux from setting permissive mode so the supolicy is your only alternative. Besides I read a comment from Chainfire who indicates that using permissive mode system wide is poor security practice. On my Nexus 5 which is running marshmallow I found all I needed was two supolicies to get all my root apps running and they were for V4A and stickmount.
The supplied V4A flash file installs V4A in /system/priv-app, sets permissions and attempts to delete two apps that the stock Samsung firmware does not have. Those audio apps are in the Google stock firmware and do no harm as there is nothing to delete. The flash file is based off one for V4A on a Nexus 5. I choose to not delete the Samsung audio app as some people may want to back it up, besides I documented three ways to deal with that app.
I hope you enjoy V4A.

This thread is impressive it work !!!!

Thanks. Tried this on my tab S. Works.

RocketPlayer is another music app that works with V4A.

Wow, I wish I had seen this thread sooner. Maybe I can fix the sucky Bluetooth performance in my tab now! Can't wait to try it. Thanks!

Working perfectly in Galaxy Alpha (g850m - Exynos) with enabled root and native kernel, including the Mix Radio (without special settings).
Thank you so much you saved my travels to work !!!

Does V4A not work on KitKat? I decided to downgrade back to KitKat but can't get it to work.

Yes the app works on KitKat but the directory structure for apps on /system changed. I'd suggest going to the ViPER4Android XDA forum and searching for KitKat installs. That forum link is in the OP (first post).

Ok. Thanks for the reply!
Edit: So, I was't able to find anything there about Kitkat specific installation, but I did find someone that help me figure out what my issue was.

Wow.. Excellent its working on my samung J2 J200F
Very very thanks 3DSammy, I rooted my new samsung j2 only for viper4adroid and I tried a lot and failed and many times ended in boot loop but this time Great Success, Its working fine on Stock Rom with TWRP recovery. But its only working perfect in compatible mode only (normal mode just work for some seconds only then processing stopped) but no problem I am happy .

Fireos 5.1.2 3rd gen

I have a KF HD 7 and I was wondering if I could root, install Roms, and other fun stuff. Is this possible on the latest Fireos? Kingroot doesn't work(i tried multiple times), the new rootjunky super tool doesn't work. Anyone know of anything else that would work? Is it possible in this situation?
Side note: I also have an Hdx 7 3rd gen w/safestrap and cm11.

[Zip]Dolby Atmos Oreo working! **also Dolby Digital Plus apk**

**As an alternative, Dolby Digital Plus apk can be used. No root required.
It's not as comprehensive but will enhance your music listening experience.
Dolby Digital 1.6 app can be downloaded here:
https://devfiles.co/download/Nq44yRMN/Dolby-Digital-1.6.apk
This version of Dolby Atmos is working on Oreo. Had no luck with other versions.
I downloaded DolbyAtmos_Axon7_Oreo_20180125.zip to be precise.
I installed via recovery TWRP. Not Magisk. I took no other steps than to download the file listed above, install via TWRP and reboot.
Later I installed Viper4android via Magisk. Both are working fine.
Thanks guitartedhero for this!!
https://forum.xda-developers.com/android/software/app-dolby-atmos-axon-7-oreo-port-t3740508

is there a way to install this without Magisk but Super SU?

I did install using TWRP and did not use magisk. None of the existing magisk modules worked for me. I don't believe SuperSU would be a hindrance at all.
Hope that helps!

This didnt work for me in the latest SuperXE ROM.
My phone went bootlooping.

Also, install via TWRP not Magisk. That's what's working for me. Good luck now!
I'm on superxe room myself. Other versions made me bootloop. Make sure you download DolbyAtmos_Axon7_Oreo_20180125.zip. That's the one that's working for me.
Best of luck!

How do we know if dolby atmos is enabled after downloading viper and this mod?
I downloaded the zte axon 7 unity version and flask in magisk but got force close every time i open the dolby atmos app. Is that the one you uses?

I never got any of the Dolby modules to work for me through Magisk. Maybe some have, but I did not.
Instead i installed this particular zip version with my recovery TWRP (not Magisk) and it is working fine. Make sure you install by booting into recovery, then installing it via TWRP.
Make sense? ?

Anyone had luck on lineage 15.1????
Is it working on Oreo ? Did anyone found any difference in audio quality???

Does not work still. Maybe bc my rom has an audio effect built in already? Im using RR neo angler remix . It has audiofx in

I have nexus 6p w/SUPERXE-8.1.0 and Magisk
This Dolby works for me (DOLBY-AXON7-Oreo-Unity2.20.18.zip
Thanks very much for the work you have done

I'm glad it's working for folks! I'm enjoying it. Viper as well!

Please let me know if it doesn't work for you and I'll do what I can to help.
It's working with Viper4android, too!

I see some are having trouble getting this to work. Please comment and I'll try to do what I can to help. Thanks!!

Will this work on my 6p running Resurrection Remix Oreo? And how do i install viper4android? RROS comes with audiofx but its not all that good at times.

I have no reason to believe that it would not work.
I personally installed this module through TWRP. Not Magisk. But I did install Viper FX through Magisk. Both are working.
Anything else that I can do to help, I would be glad to try. Thank you. Sincerely.

Clear sound mod corrupted error when trying to install from TWRP
EDIT: It was my zip that didnt download completely. However, it doesnt work for my bluetooth headphones on Pocophone f1 running LineageOS 16. It works for phone speakers however, and havent tried corded headphones yet.
How to uninstall them? Just flash them again?

AFAIK the only way to uninstall would be to dirty flash your Lineage OS ROM (reinstall Lineage without wiping your data. Just wipe your Cache and Dalvik Cache). This should keep all your apps and settings intact but remove V4A and ARISE and reinstall the stock drivers that come with Lineage. In my case I also had to reinstall Magisk.
---------- Post added at 11:13 PM ---------- Previous post was at 11:05 PM ----------
This doesn't work for me on LineageOS for MicroG 16 (Google Pixel XL 'marlin'). ARISE crashes, and V4A tells me I need to reinstall the driver every time I open it. After reinstalling, it tells me I need to reboot. After I reboot, I tells me I need to install the driver again and this loop just continues forever.

Unluckily here doesn't work and crash all the time.
I guess no way to uninstall, right?
I am on latest havoc os for mido...
Thank you

Dirty flash of Rom should remove the mod. But don't you have any remnants of other mods left? Something like that caused crashes to me some time ago. Additionally, I had to remove Audio Modification Library from Magisk to get this work.

Nope, no any other mods installed didn't try anything else before. Probably havoc has dirac inside, but I don't use it because I don't like and I can't remove it I guess.
Tried with and without aml on magisk but it's almost the same. Dolby sometimes works sometimes crash, viper for arise doesn't work at all.

One more thing I had to do was setting SELinux permissive. As last resort, but it worked for me
I gave a try V4Android 2.7 also, but it is even more unstable for me, unfortunately...

I installed but dolby and viper not showing.

Working bad in pixel experience.

Flashed it on nitrogen os pie but didn't see any app in app drawer...

Do you have uninstaller file for this dolby atmos?

Hey guys,
Is there a way to install this mod on a pixel xl - marlin (any ROM crdroid, EvolutionX, stock)?
The installation in the TWRP is carried out without errors. The apps are available in the system. But viper app says "driver not installed".
