RikoMagic MK802IV Modifications Not Remaining

Hello everyone. I am trying to modify system.img, the kernel, boot.img, and the boot animation on my Rikomagic MK802IV. I can edit system.img, but NONE of the changes stick. Also, I cannot open boot.img or kernal.img. Does anybody know any tools that I can use to help this process along? And does anybody know how to edit the boot animation? I can change it all I want in bootanimation.zip, but when I actually restore the device using the new system.img nothing at all changes. It is almost like there is a proprietary boot animation embedded somewhere inside.
