Mayne would you add this to your ROM ->
I put it on my LWW and it's working.
I haven't used CM10 but I tried CM9 on Neo V and the only thing I didn't like about it is the stock camera UI. It'd be too good if you manage to keep the original Sony camera UI on CM10 ROM. I guess most of users will agree with me.
I was searching factory files for A56 all over the net but couldn't find anything and ROM dumps never worked. But finally a guy at GSM-Forum had uploaded them. It's a zip file, you can get it here
