How-to:

nb: if you have already installed dolby-framework inside your framework.jar, please delete it first before paste from my dolby-framework
4. Compile your framework.jar
5. Move to services.jar, we need to disable signature on this step (this is maybe make it stuck on dolby logo when opening the dolby app)
nb: if you already patch your services.jar, skip step 5-9
6. Decompile your services.jar and look for /com/android/server/pm/PackageManagerService.smali
7. Find this method:
Code:
.method static compareSignatures([Landroid/content/pm/Signature;[Landroid/content/pm/Signature

I.locals 7
const/4 v0, 0x0
return v0
.end method
9. Save your services.jar and recompile your services.jar
10. Download dolby_flashable.zip HERE

14. Flash dolby_flashable.zip
15. Done
NB:
1. Another mirror/s is not allowed!
2. If you have another audio tweaks installed like viper/dsp/etc, please uninstall first (it may cause conflict/FC)
3. If you have any issues about compiling *.jar files, try this one -> Baksmali manager i am use it for compile/decompile *.jar files
nb: i'm forget who share that tool, so i just can say thankyou!
4. Free space /system (±) 10MB
5. May will be work on all device running on KITKAT, so let me know it works or not
