I am trying to debrand a w760a (R3CC007) does it matter which firmware I use, I suppose I should just use the latest? and then the Russia and DE languages on the FS and MAIN files don't really matter right? seems I used the CHINA version with my W580i...

also, does the language on the custpak matter? what matters and what doesn't? there's so many choices for the w760 phones.

Thanks in advance!
