Try using Sony PC Companion to reinstall Lollipop.

If you can't or it doesn't solve the problem, contact Sony Xperia support to get the phone checked out.

What do you mean by "flashed the phone"?

You can still try to reinstall software through PC Companion as Phy suggested. Here's a complete guide how to perform software repair using PC Companion, you need your phone charged, powered off and disconnected from PC before you start.
