Added line to save prop file in case it doesn't exist

            // Try to load the build.prop from two possible paths:

            // - builds/CURRENT_ZIP_FILE.zip/system/build.prop

            // - builds/CURRENT_ZIP_FILE.zip.prop ( which must exist )

            $this->buildProp = explode( "\n", @file_get_contents($this->getPropFilePath()));

            $prop_contents = @file_get_contents($this->getPropFilePath());

            if(!file_exists($this->filePath.'.prop')) {

                file_put_contents($this->filePath . 'prop', $prop_contents)

            }

            $this->buildProp = explode( "\n", $prop_contents);

            // Try to fetch build.prop values. In some cases, we can provide a fallback, in other a null value will be given

            $this->timestamp = intval( $this->getBuildPropValue( 'ro.build.date.utc' ) ?? filemtime($this->filePath) );

            $this->incremental = $this->getBuildPropValue( 'ro.build.version.incremental' ) ?? '';
