I did it yesterday (24/7-15). It only says that Android is starting and that the phone is optimizing apps...after a while my phone doesn't work at all or just restarts again.</P> <P>What is wrong? What can I do about it?</P> Sat, 25 Jul 2015 11:19:23 GMT https://community.sony.si/t5/xperia-archive/after-latest-update-phone-doesn-t-turn-on/m-p/3421978#M504923 juventus 2015-07-25T11:19:23Z https://community.sony.si/t5/xperia-archive/after-latest-update-phone-doesn-t-turn-on/m-p/3421979#M504924 <P>Try performing a system repair using <A href="http://www-support-downloads.sonymobile.com/Software%20Downloads/PC%20Companion/Sony%20PC%20Companion_Web.exe" target="_self" rel="nofollow noopener noreferrer">PC Companion</A> as this will often fix issues - This will factory reset your phone and erase all data</P> <P><BR />Switch off your phone and unplug from Pc (Hold volume up and power for around 10 seconds)<BR />Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the on screen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process<BR /><BR />If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP</P> Sat, 25 Jul 2015 13:36:32 GMT https://community.sony.si/t5/xperia-archive/after-latest-update-phone-doesn-t-turn-on/m-p/3421979#M504924 Thommo 2015-07-25T13:36:32Z
