While system software updates can be used with consoles from any region, Sony recommends only downloading system software updates released for the region corresponding to the system's place of purchase. System software updates have added various features including a web browser, Adobe Flash Player support, additional codecs for images, audio, and video, PlayStation 3 connectivity, as well as patches against several [[Known Exploits and Vulnerabilities|security exploits]], [[Known Exploits and Vulnerabilities|vulnerabilities]], and execution of homebrew programs. If the power supply (Battery/AC) is disconnected while updating the [[Firmware|system software]], the console will be [[Brick|bricked]]. The system will have to be booted from a different source such as a [[Pandora|battery in service mode]] with which it can be restored.
