increasing phone internal memory from 4Gb to 16Gb.

[naz ele]

I used 32Gb SD, I tried to get 16Gb internal memory, I did 2 partition (16Gb FAT32, 16Gb ext2).
but on my rooted " # " Android JB 4.2.1, 1Gb Ram, 1.2Ghz Quad Core CPU, the ext2 did not recognized by Link2SD app.
what shall I do any idea?
I guess thats my memory is NAND - ON, how I can make it OFF :'(
