Something gone wrong during your firmware flash.  Run pc companion to repair or flash update again.

you need to re-run the update process but this time you need to use Sony Update Service.

before you start,pull out your battery and wait for 5 seconds then,insert it back..

wait for 30 seconds but do not turn on your phone.

after that,follow every steps shown on the SUS.

have a nice day
