Default How to remove DSP or how to make it work.

Hi guys... I just flashed DSP on my 4.4.2 ROM stock and m-kernel (after wiping cache and dalvik cache) but it doesn't work, i don't know why (it has a fc) .... what can I do? To remove it do i have to delete it from system/apps?
Do you know a better mod for nexus 7 (1 gen)?
