Once you've flashed this you will have the option to turn on NFC in Wireless Settings as well as be able to install NFC apps from the Play Market.
- Reboot your phone into Recovery if you've already installed ClockworkMod Recovery. If you don't know if you have, you probably haven't. Go here: http://forum.xda-developers.com/show....php?t=1526431
- Make a Backup! This doesn't do anything fancy, but I'm not responsible if you lose everything when flashing. CWM is still technically a Beta build for this phone
- Choose "install zip from sdcard"
- Choose either "choose zip from sdcard" or "choose zip from internal sdcard" depending on where you saved it.
- Find your file and install it
- Restart. You now have NFC options.
