The ans is damn easy Just download factory image of the version you want to install (plz select factory image correctly according to your device)

install NRT kit and follow steps for installation given on this site.

and that click on stock rom +unroot and direct it to your downloaded factory image and in minutes your phone will start working .I also did something of same kind

Download CyanogenMod 11 M10 .zip file and GApps for 4.4x .zip file on your computer.
Open TWRP. Go to Advanced Tab. Click ADB Sideload. Swipe to start Sideload.
Open the folder where you've downloaded the files. Hold Shift and right click on your mouse. Select Open command window here.
Type "adb devices" without the "". Check if device is listed or not.
Type "adb sideload <cyanogenmodfilename.zip>" without the "" and <>.
Wait for uploading to finish.
Press back button on TWRP on your device. Again enable ADB sideload as described above.
Type "adb sideload <gapps.zip>" without the "" and <>.
Wait till uploading and installation is finished.
Click reboot. Enjoy!

Just flash the factory image fromhttps://developers.google.com/android/nexus/images
And flash the. Image using nrt
