Fully Working Harman / Kardon "conversion" for all HTC ONE M8 variants!-discountinued

WARNINGS - READ before you proceed further!

- Does NOT work on GPE, put Sense on it and it will work

- Users with stock ROMs (especially US), if your base number is 1.1x then H/K won't show in your settings because it simply lacks the code. update to a newer base or flash a custom rom

- it is recommend to have S-OFF

- do NOT attempt this on m7. IT WILL BREAK YOUR PHONE!

Installation

Depends on your luck you might also need S-OFF to fully benefit of this hack - i say might because depending on your firmware you might need to update ADSP (Advanced Digital Signal Processor) as firmware as well and for that you need S-OFF.

If you are S-ON and feeling lucky grab View attachment hk_enable_v3.zip and flash from recovery. it will only enable H/K in settings and update the rom files for it

If you are S-OFF grab View attachment hk_enable_and_adsp_update_v3.zip with all in one zip solution. it will do anything from enabling H/K in settings to updating ADSP.

For uninstall grab the zip from the bottom of this post

Troubleshooting

ISSUE 1: I've flashed the zip and after reboot I do not have HK in Settings!! HALP!!!

Reason: Happens because you did not have false line in system/customize/ACC/default.xml so script did not find it so it couldn't replace false with true

Solution::go to /system/customize/ACC/default.xml
search for and just it below it add:

true

The final result should look like this:

Code:

<app name="Android_Multimedia">
  <item type="integer" name="has_default_alarm_volume">6</item>
  <item type="integer" name="has_default_media_headset_volume">7</item>
  <item type="integer" name="has_default_media_speaker_volume">10</item>
  <item type="integer" name="has_default_ringtone_volume">5</item>
  <item type="boolean" name="spport_screen_light">false</item>
  <item type="boolean" name="support_a2dp_safevolume">false</item>
  <item type="boolean" name="support_camera_enforce_shuttersound">false</item>
  <item type="boolean" name="support_customer_proxy">false</item>
  <item type="boolean" name="support_customization_fallback">false</item>
  <item type="boolean" name="support_harman">true</item>
  <item type="boolean" name="support_miit_request">false</item>
  <item type="boolean" name="support_music_ringtone">false</item>
  <item type="boolean" name="support_outdoor_mode">false</item>
  <item type="boolean" name="support_qcelp">false</item>
  <item type="boolean" name="support_theater_effect_logo">false</item>
  <item type="integer" name="use_ringtone_for_notification">1</item>
</app>

Reboot. Profit!

ISSUE 2. I have HK and everything but when i play mp3 in HTC Music app i hear nothing. HALP!!! you broke my phone

Reason: Happens because you need to update your adsp (Advanced Digital Signal Processor) firmware.
Solution: You should have flashed View attachment hk_enable_and_adsp_update_v3.zip but i repeat you need to be S-OFF for this, if you are S-ON afraid you are out of luck

ISSUE 3 I did everything and it still doesn't show up on my Verizon M8

Reason: Happens Because Verizon uses a different settings.apk.
Solution:Grab http://xdaforums.com/showpost.php?p=54272102&postcount=940 and flash from recovery

ISSUE 4 I did everything and it still doesn't show up on my phone

Reason: Happens Because you have a stock 1.1x base rom on your phone which simply lacks the code for HK in settings
Solution: update to a 1.5x base rom (custom or stock)

@baadnewz

For which reason some ppl have no problems (like me) with sound in Music App but some have?

Has it to do with the Firmware 1.54.401.5 WWE and ppl on other Fw?

Further the initial zip from here http://xdaforums.com/showpost.php?p=52294479&postcount=2810 worked out of the box for me yesterday. Only difference to your Zip is the included system/etc/audio_policy.conf. Do I still need to flash something from here, e.g. Firmware?

b0gd4n · May 1, 2014

your mod doesn't disable BoomSound. It sometimes conflicts with H/K.

Here's lyapota's mod which also does this, but also disables BoomSound.

So your answer means

1. My DSP is up-to-date.

2. The included audio_policy.conf in other zip is not important?

BOOMSOUND and hk switches can be disable and enable by a simple edit in xml you don't need a flashable zip for that The real problem was issue number 2.

So keep you stuffy right

1.54.401.5 firmware is international one and does not have Harman in it so you have to update

Which conflicts are you referring to? Thus far I have had none using Baad's method.

But the Issue with not existent MP3 Audio is not existant on my device. That's why I ask...

the_scotsman · May 1, 2014

So what exactly does this do? Where is it taken from? Does it improve sound quality, or just boost the bass or highs or something?

It was taken from m8 h/K version and it should improve audio quality

Some have it some don't. I had to update adsp myself to get it working while for others worked out of the box

Even when I have no problems, flashing a newer DSP Fw cannot be wrong

...did it.

So flashing the adsp firmware on Verizon HTC one is fine? I flashed and did issue 1 and its still not showing up so want to do issue 2.

If it's not showing up after doing issue 1 then do not proceed to issue 2 because it on fix not showing in settings. Verizon might need some editing.

Flashed the hk_zip worked immediately. Through headphones it's definitely noticeable. Much improved bass. Through the external speaker can't really tell a difference.
