Hello and welcome to this Android Forums!

Please proceed with caution for reloading ROMs. I am not responsible if this breaks your phone!

I found an article about the Xperia S, I am not sure if this is the phone you have or not. Please read this forum:

Read the whole forum but read post #3 specifically.
It looks like there are a couple things to try before you have to rollback to a stock ROM.

Here is the Sony flash tool:

If this does not work for your device please repost a question back.
