I modified my launcher.apk but I can't figure out how to put the modified version on my phone. I would put the file where it belongs /system/app but it fails to install. So I then tried to use ddms to push the file but still the same thing. So I put my phone in recovery to push the through ddms that way, figured maybe phone shouldn't be running, but I can't do anything on ddms when my phone is in recovery.
