Sony Tablet S won't start after update

[HeartLakeTraveller]

Just received a update notice this morning for a new OS update for Sony Tablet S (4.0.3 or something like that). After installing , the tablet will no longer start up when the little lock is touched, as it used to. Is there a fix?

Hi. This happened to me also. I simply hit the reset button and it's worked perfectly every since.
