How to Update Sony Xperia Z to Android 4.2.2 Jelly Bean
Although the update is not available OTA, so we can not locate only from the smartphone, it does seem to be available now, at least in some regions of the world, computer programs for Sony. So, if we have a computer with Windows operating system, we have to use PC Companion, or if we have Mac, Bridge-, to update the Sony Xperia Z to the latest version. Only have to connect to the program, sync, and trying to locate firmware updates. If neither is available, it is because we still have to wait a few days to also be available in Spain.
