Calculator GTA San Andreas on RK3066 (mali 400 mp4) on android 4.1

So, the problem - on my CUBE U30GT (RK3066 + android 4.1) GTA SA has black textures in game, only hud is visible.

On some 4.2 roms (oma, for ex) SA works (slow), but the rom no usable for me - its slow then all 4.1 i've tryed. Thus, we have no 4.2 android on U30GT yet.

I guess, the problem in mali drivers, which was solved in 4.2 roms. But how to get work SA on 4.1?

Thanks and sorry my english)
