ok so I reflashed main, fs and custom all of the same version and region - now I have all baltic languages, but when I replaced en.lng, it was still the same - no camera controls appeared, but when I changed ru.lng, the russian variant worked... so now I have to use russian language to use the camera controls. But why doesn't en.lng work ? If I choose "according to SIM" it also puts English language, maybe that's why it can't be replaced ?
ok so i got it working now: i renamed modified en.lng to lt.lng and replaced the other language, now i have two English languages in the selection menu :)
