not sure if this would help,....but.... i would erase both xs++ and Far... and use the all-in-one-pack form here--->

The All-in-One W810i Pack - Top Sony Forums

follow the steps exactly as explained.....

i also have a W810 with CID49.... and it worked great for me....

and have also added the flash menus as seen on this guys you tube vid--->

YouTube - w810i w810 with new flash menus

good luck..
