[HTC Droid DNA] docnok63:
I just installed it using the Aroma installer. I chose Universal>Universal>Skip>Noozxoid. I'm using it in conjunction with Beats rather than in lieu of it. My Klipsch Image ONE Premiums have never sounded better. I HIGHLY recommend this installation for anyone. The work these folks have done is incredible.

*Note* the final window says you should not have any other DSP or equalizer installed. I had DSP Manager v2 installed and I let it install anyway. There were some conflicts and AC!D actually FC'd. I had to turn off all DSP Manager's options and disable it. I then rebooted and no issues afterwards.

****NOTE**** I take no credit for the original work. This is simply a port to the DNA. The original thread is here:

Folks, install this now. Seriously.

12/27/12 UPDATE: Tonight I mistakenly found out why the installer says not to have any other DSP's installed and why when you go into Settings\Sound\Music effects it FC's. If you did the Aroma installer and followed my installation and look in your applications, you have a new icon called Noozxoide EIZO-rewire. This is their Jelly Bean DSP manager suggested in the installer. If you click Build-In Audio Monitor (supposed to be built, but they're German, so give them a break), you can FULLY manipulate your sound to your liking. I'm enjoying my headphones even more with these tweaks and I'm sure you will too!!! See new screenshots below.

12/28/12 Disregard. See instructions below.

12/29/12 UPDATE: Looking at the original AC!D post, I noticed that my installation was incomplete. Steps 9 and 10 involve a build.prop edit. I've successfully done it and I want you all to hear what I am.

******WARNING***** Follow these steps EXACTLY. If you do not, you could make your phone unbootable. I'm not responsible for any damage to your phone. With that said, let's get to it:

1) First, you need to be on any version of TWRP recovery and have adb installed.

2) We're going to make a backup of your original build.prop first. Put your phone in recovery and plug it into your PC. In TWRP select Mount and mount System. Go into a DOS prompt and type:

adb pull /system/build.prop C:\

3) Right click on build.prop and select copy. Paste right there in the root You should now have two files on your root like the fourth screenshot. Right click on build.prop and open with Notepad. Scroll to the bottom of the file and hit enter. On the new line, paste the following code:

###AC!D Sound Tweaks by R-ikfoot###
#Sony Xloud & Clearbass +
ro.semc.sound_effects_enabled=true
ro.semc.xloud.supported=true
persist.service.xloud.enable=1
ro.semc.enhance.supported=true
persist.service.enhance.enable=1
ro.semc.clearaudio.supported=true
persist.service.clearaudio.enable=1
ro.somc.dmnorm.supported=true
persist.service.dmnorm.enable=1
ro.sony.walkman.logger=1
ro.somc.clearphase.supported=true
persist.service.clearphase.enable=1
#Resampling
af.resampler.quality=255
persist.af.resampler.quality=255
#Beats Engine
htc.audio.swalt.enable=1
htc.audio.swalt.mingain=14512

(See the fifth screenshot.) Close Notepad saving your changes.

4) Now send the edited build.prop back to your phone. Go back into your DOS prompt and type:

adb push C:\build.prop /system/build.prop

4) ***If you don't this, your phone is unbootable*** Go back into TWRP and use the File Manager to navigate to the system folder and find build.prop (scroll all the way to the bottom.) Click it and press the Chmod 755 button. Swipe to confirm. Make sure you get a "Successful!" at the top. Go back to main menu of TWRP and reboot system.

5) Profit! (If you have an app like Root Explorer, you should see the build.prop looking like the sixth screenshot.)

12/29/12 SECOND UPDATE: If you use either one of DSB's kernels that enable system write, you can use several apps that allow you edit the build.prop while booted into Android. The confirmed list, so far, is

ES File Explorer: https://play.google.com/store/apps/details?id=com.estrongs.android.pop&hl=en

Build Prop Editor: https://play.google.com/store/apps/details?id=com.jrummy.apps.build.prop.editor&hl=en

Root Explorer: https://play.google.com/store/apps/details?id=com.speedsoftware.rootexplorer

Directions for the Explorer apps:

1) Navigate to the system folder and mount it as Read/Write capable.

2) Make a backup copy of the build,prop

3) Navigate to this thread with your phone's browser and copy and paste the code from step 3 above at the end of the file. Save your changes and exit the app.

4) Do a full reboot and profit.

Directions for Build Prop Editor:

1) Fire up the app and hit the menu button. Select Backups and create a backup.

2) Go back into the menu and select edit...

2) Navigate to this thread with your phone's browser and copy and paste the code from step 3 above at the end of the file. Save your changes and exit the app.

3) Do a full reboot and profit.

1/3/13- There's a new build of Noozxoide DSP, but the Play Store says it's not compatible with our device. I've found it best to sideload it in recovery. Instructions:

1) Download the .apk from: http://xdaforums.com/showthread.php?p=36168124#post36168124

2) Put the .apk in the same folder as adb.exe.

2) Boot into recovery and mount system.

3) Type in:

adb install com.noozxoidelabs.eizo.rewirepro.apk

The install will complete with an error code, but it did install fine. Look in Settings\Apps\All and you should see new build number (see screenie #7)

*NOTE*-- For those of you that want to install the Walkman player, it specifically says in the OP of the Engine and the Aroma installer that you can NOT use the player with a DSP. Your installation in Aroma should be Universal, Universal, Walkman, Skip.

1/26/13- After some extensive testing (a LOT of flashing and restoring), I've come to the conclusion that the AC!D Engine either just doesn't work on our device or it doesn't work on any device. What I heard as a significant change in sound actually came from the Noozoxoide DSP and not from the Engine. A properly running Nooz sounds amazing combined with Beats on this phone. First, my test results (all v5 tests with proper build.prop edit. v7 supposedly doesn't need an edit):

AC!D v5 only: No change to sound

v5 with Walkman 5: No change

v5 with DSP Manager v2: Only DSP changes

v5 with Noozxoide DSP: Only Nooz changes

AC!D v7: phone boots, no changes to sound

AC!D v7 and Walkman v6: Phone won't boot into Android

v7 and DSP: DSP changes only

v7 and Nooz: Nooz changes only

The choice then becomes which DSP sounds better to you (DSP Manager v2 or Nooz.) I just sideloaded the latest version of Nooz (2.0.1.13) and I adjusted its settings to run with Beats. I don't think I could be happier with audio coming from this phone. Links:
