Hello. I have found too confusing to find right thread about root for s4a 9295. Most threads about root are mixed with i537, so i think separate thread for 9295 regarding it will be good decision.
1. Install custom recovery via Odin ...
Just for clarity: I am not a developer. I have took miui port for su640 (port from lu6200) from MIUI.com and port it for P930. So if these roms have some problems or bugs i can't help you. I am doing it just for myself because i love miui ...
Installation process was successful. ROM works. Calls look OK.
