[Q]Change Navigation Bar Height in [ROM][PORT][CM9.2][Touchwiz Revolutionised 5 topic

I like ONscreen Buttons... So i Enabled it in "Touchwiz Revolutionised 5 by arpitkh96".. but the height is 39dip which i thought more for our phones..

I tried Decompiling nd change the navi bar Height
:
i followed this Method:
1)decompiled the framework-res.apk using apktoool ..
2)went to res folder>values folder
3)opened dimens.xml file in values folder..
4)edited these two lines:
<dimen name="navigation_bar_height">20.0dip</dimen>
<dimen name="navigation_bar_width">24.0dip</dimen>
5)Again Compiled it and the size of the framework-res.apk got reduced..
6)but i pushed it into my System folder and changed permissions..
7)after that i pushed it into framework folder..

After that my phone got struck at booting image...

Can SomeOne Help me in this....?
