So I'm trying to theme an app, Thumb Keyboard. I've tried opening the apk from TI/Astro backups and repackaging it, which didn't work, because the app manager didn't recognize it. I tried Ninjamorph, but it just makes the app stop responding every few seconds and pop up that FC dialogue. When I uninstall the patched app, the phone soft reboots. So how would I go about theming the keyboard by replacing the png files in the apk? They're the same res, still png files, and I edited them in GIMP.
