All problem starts after 20140615 nightly of CM11 made by Mustaavalcosta. Problem is i can't able to install any rom which made after that date. So i've contacted him and he provided me as much as can.
But Since i'm the only one who is actually having issue with nightlies so he offered me to format devlog partition using .zip provided by him. I did and provide him a recovery.log where he couldn't able to trace any issue.
Now condition of the device is like, If i reboot my device, it will hangs in bootloop and doesn't boot. Until i flash boot.img via fastboot. But then also it will reboot atleast twice with 5-10 sec interval and on 3rd reboot it will boot normally. So is it some sort of Hardware failure issue? Also before formatting devlog partition i've made full backup of device but it seems like after Full wipe and restoring device from backup,It reboots twice as i mentioned earlier,Only way to work around is to flash boot.img then it will boot properly on 3rd reboot all happens automatically.
Status of device:
