After more test i have more info, when i press home button for 5 seconds it asks me to power off console. And when i add second controller the first one still flashes the screen, but second home button works, i have no idea what is going and how to fix it...
I found the problem, it was plugin - xblstealth, when i deleted it from hdd and remove from dashlaunch than reboot the console and everything is working, hope this will help if anybody have same problem.
