http://www.xperiablog.net/2015/03/17/guide...-and-flashtool/ The above guide show me how to flash the android 5.0.2 for my xperia z . I'm using ori Sony xperia Z msia set . The update havent reach Msia althouth the update has been rolled out nearly 1 month . I dun wanna wait anymore , so I decided to flash the new firmware . But , I am all new to this . How to revert back to Msia firmware again if the update has reach Msia one day ? Just backup the data using PC Companion would be enough? Need to format the phone first ? Just sign in to the Google account after format and all the apps will be automatically installed back to the phone again?
