this firmware is purely for Russian language support, it is NOT a replacement firmware, but just a hack to the original one.
So the folder structure has not been changed - still collections only.
I dont believe there is an alternative firmware for the newer models yet...
ps there are some other changes, like an ability to assign different actions to zoom and Options button (eg you can make them into page on/page back buttons).
I am using this altered firmware and it seems stable to me - havent had any problems with it.
Hope this helps!
