K810 Patch for upper keys

I have a K810 R8BA024

I used to have a cool feature in K800 with an old firmware.. I get to scroll thru the camera pictures in landscape mode using the upper buttons of my K800.. I upgraded the firmware to K810 R8BA024 and lost that feature.. I cant get my old firmware back.. Now is there a way to fix or get that feature back?.. May be a patch or something?..

Seems no body here know how to make the upper keys work.. Or maybe its just not possible with a patch.. How bout whats the last firmware that supported the upper keys to work in scrolling pics in landscape mode?.. Thanks..
