The only way I know how to do it is pull the apk of the file you want to change, edit the .png files to your liking and resign it so it will work.
This app, Auto-Sign.zip, has worked quite well for me. It's simple to use and all the instructions are there.
I use auto sign because it's simpler than using adb. Just resign it, put it on sd card and install that way
I was never able to get the signing thing to work. Adb is easyas long as you know what lines to copy and paste.
That's why I find auto-sign much simpler, don't have to worry about the lines in cmd.
Which signing tool did you use? I tried one or two that would never work before finding auto-sign and now it works like a charm every time.
