[AleksandrArchipov]

Hello! I decided to do a master reset on this unit. Through the menu options and went to press the reset. Phone is switched off and is no longer involved. Tried to connect to the flash modes, pc compin. flashtool did not see. The computer says unknown device. The phone connects to the computer without the battery. Prior to discharge this was not. Sorry for my English.

Sounds like there may be something wrong with the phone or battery i'm afraid but try charging the phone for a few hours and also try repairing the phones software using another computer and see if it helps. I not, i recommend that you contact your local Sony Xperia support (http://www.sonymobile.com/global-en/support/contact-us/) or a service location for assistance.
