  2. Yep! You can find a good package to flash http://en.miui.com/thread-217297-1-1.html here! Uninstall the drivers then flash the zip you want via recovery. It will install the drivers and audio libraries.

    Oh thanks that's awesome
     
  4. You welcome, I tried lot of things before finding this thread, like switching manually SELinux from Enforcing to Permissive after each reboot ^^ Now it's easier! Can't live without V4A!

    Yeah clearly this mod is a really good stuff :)
    Wich one do you have? V4A Atmos+Sony+Beats v5.5 or only the v4a ?
     
  6. I took the ultimate package to give it a try ^^ Depending on battery consumption, maybe I will change for only V4A. I have to admit the sound is quite massive! But I don't use Atmos which IMO is "too much", I don't fell my sound it does, it adds lots of reverb. But it depends on the type of music you listen to.

    I took v4a + Sony + beats
    Yep the battery is affected at least 20-25% more than usual I think
    Depend on wich device you got for the mi4 no as its not locked but other one yeah you need to unlock boot loader

    Yes you should be root and no the big advantage of this is that you don"t need selinux or other mod you flash the zip and it's done

    Hi.. Installing V4A @ smiui 6.5.5 @ Mi4-LTE (V4A Atmos+Sony+Beats v5.5) was no problem..and it works! But I can't save any effect-profiles / load any IRS because V4A doesn't have a working dir..

    Code:
    05-07 13:56:48.989  3752 19343 I ViPER4Android: Now checking for external storage writable, file = /storage/emulated/0/v4a_test_file
    05-07 13:56:48.990  3752 19343 I ViPER4Android: FileNotFoundException, msg = /storage/emulated/0/v4a_test_file: open failed: EACCES (Permission denied)
    05-07 13:56:48.990  3752 19343 I ViPER4Android: Now checking for external storage writable, file = /storage/emulated/legacy/v4a_test_file

    05-07 13:56:48.990  3752 19343 I ViPER4Android: Really terrible thing, external storage detection failed. V4A may malfunction
