    2. After that switch to "Select zip from sdcard" and press power button again.
    3. Now select the ChainFire SuperSU zip file in the root of your sdcard, which you copied in step one.

So using these directions will preserve data? I thought when you flash userdata you are wiping your data partition?

Followed your instructions to the letter and everything worked great, however, my device is only showing I have 6GB of total space on a 32GB model! I've never run into this problem before with all the roms and restores that I've done. Any suggestions?

I just noticed the same. I'm going to see if rooting and doing a complete wipe helps.
