Seems like you have tried everything like repairing and manual flashing so all I can say is to contact Xperia care - The things I would have suggested you have already done or maybe remove the Sim card and micro sim and try that - Don't know what good it will do but it's a final thing to check http://www.sonymobile.com/global-en/support/contact-us/
already tried that to but in iran there is no official sony support center already emailed sony they said that i can send my Z1 to them in UK by post so they can repair or replace it but once again for this country if i send it to them and they be able to fix it there is gone be huge price for imporing a mobile phone by post for me!
