3- change file name to update.zip and put it in sd card
4- now boot your phone to recovery boot by pressing vol+/home/power
5- then chose install from sd card you will see the file update.zip
it will takes up to 10 mins
Thats all and that what i did exactly and i have 4.4.2 unrooted now enough for me
