I basically wanted to change the battery icons to a different set. I tried Ninjamorph. It didn't work. I tried to open with 7zip and just copy the images in. This worked, but when I booted my phone, facebook and gtalk authentication broke. I could fix facebook, but it took forever to fix gtalk authentication. So how am I supposed to do it? Am I screwing up the permissions of the framework-res.apk file when I modify it in 7zip?
