Default [HELP] Change mouse pointer Cyanogenmod 10.3 (Android 4.2.2)

Hi
I need to change the mouse pointer in a Samnsung Galaxy Tab 2 10.1 P5110 with Cyanogenmod 10.3 (Android 4.2.2)

I've found several pages where explain how to do it through changing pointer_arrow.png file in framework-res.apk and then overwritting it in /system/framework, but when I do the tablet reboots itself and keeps on looping in the logo screen

I'm already root (thanks Android-Andi for that) so that's not the problem
I also modified the rom before installing it but still geeting the loop
