You need adb to push the files. Search for the Android SDK to install it. Or you can use winrar to open the apk file and delete the files in system and framework folder that you do not want. So if you want services.jar delete all files but for that. Do not extract and repack the apk file, just open it with winrar, delete the files from winrar and then close out of winrar after making changes. You do not need to save the file since when you delete files from within winrar it will save it and not break the signature.
