Upgrading rules

An install package can only overwrite or remove files if it is a valid upgrade of the package that originally installed the files.

Files that were not installed by an install package (known as orphaned files), can only be overwritten if the phone's installation policy has been configured by the phone manufacturer to allow orphaned files to be overwritten. If the policy is enabled, the user will be asked to permit the file to be overwritten.
