I tried both &nbsp;safe mode and normal boot. But after boot, the system is in serious lag and will reboot itself afterwards. Any solution for this? I tend not to wipe all my data.&nbsp;</P> Fri, 19 Jun 2015 11:05:40 GMT https://community.sony.si/t5/xperia-archive/xperia-z2-bootloop/m-p/3372620#M478456 dLui 2015-06-19T11:05:40Z https://community.sony.si/t5/xperia-archive/xperia-z2-bootloop/m-p/3372621#M478457 <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 so best to backup before you begin<BR /><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> Fri, 19 Jun 2015 11:25:58 GMT https://community.sony.si/t5/xperia-archive/xperia-z2-bootloop/m-p/3372621#M478457 Thommo 2015-06-19T11:25:58Z
