Not one of you have ever portioned their phones memory!!!!! shocked(no not sdcard)
You just use a scatter file with DATA EBR1 Y EBR2 and it re-writes the phones memory to what you want from 1-what ever GB
There's even a android program that will do it for you. You must be rooted and have CWM or Twirp.
Been doing this on pads\phones for years. Next you'll be saying you don't know what a EBR1 Y EBR2 is
Why are you using 'y' (Spanish for 'and')? Are you just copying and pasting stuff from another source in an effort to make it look like you know what you're talking about?
