Default Reinstalling stock ROMo

Proud xperia S owner here.
My mom got the old x10 of my brother, who did a lot of flashing on it. It has custom Rom now. Her battery is bad so I want to reflash her stock rom.

Question: what is the most recent rom for x10 and where can I download it? Can I just flash it with flashtool? Anything I need to know? It has locked BL

Thnx in advance
