First off, I'm on an IP4 on FW 4.3.2 jailbroken with redsn0w 0.9.6RC14

Now my issue. I've noticed that theres some problems getting lockscreen sliders and battery themes to apply. Some work, most don't. I'm assuming the ones that work have been optimized for the firmware I'm running (or higher). So I guess what I'm looking for is some explanation on how I can update older themes to work with newer firmwares.

Ill use these two as an example:

LED Battery

N3 Slim Slider

I've tried to use both of those with no luck, what would I need to do to get them to work with my current setup?
