Lenovo A916 Power Manager App Fails I can't turn on emergency mode in Lenovo Power Manager app, it seams broken with my system.
Emergency Mode is like classic phone mode, only calls, SMS, contacts and clock are enabled. It saves energy.
Problem
Whenever I try to activate it, it starts with Preparing data, please wait... and after that it says: Failed to launch the Emergency Power Saving mode. Sorry, but we tried our best
I've test this app on other Lenovo A916 with deferent ROM, it works there. Why is it not working with my ROM? Could someone help me find out why?

Logcat
I've made Logcat log, with hope that I will find cause of this problem and maybe fix it, but no luck. Maybe some experienced Android enthusiast will help me find out what causes the problem. Log file is kinda long but by searching prepareEnvirenmentOperation its easier to get entries
Logcat log is here
Device information:
Lenovo A916, Android 4.4.2, system build id A916_S206_141125_baralajbi
Problem solved, problem was caused by SuperSU root manager. After changing SuperSU to KingRoot it works fine. Weird.

I've tried different SuperSU settings, reboots, etc, but non of them seems to solve this issue. I got weirded out after trying this Lenovo app on my Alcatel tablet... it works perfectly fine there, with KingRoot, so I changed SuperSU to KingRoot on my Lenovo device and it works.
