Default [Q] can anyone help me using link2sd on my lg e610 using script?

hi i got an lg e610v
i've installed a custom firmware : 20d+root+cmw
installed cyanogenmod 11 and last Gapps

i've partitioned the SD card with partition magic tool
1 : Fat - 400 mb 2 : ext2 - 1600 mb

i got problem using link2sd because it tells me that it's not supported because i got a primary ext memory that's emulated from my internal memory.

i read on internet that i can exchange the emulated memory using a script like :
mount -o remount,rw /
mount -t vfat -o umask=0000 /dev/block/vold/179:61 /mnt/sdcard
mount -o bind /data/media /mnt/sdcard/external_sd
chmod 777 /mnt/sdcard/external_sd

but i think this is only for certain phones , what could i do to use both the primary and sd memory on this phone ?
thanks for the answers !
