Unpacking recovery of Galaxy core prime (spreadtrum sc8830)

Hi everyone, I'm trying to make cwm for my Samsung galaxy core prime with spreadtrum sc8830 processor. As the main plan I use this guid. However I stucked on the unpacking recovery. I tried to use different utils and kitchens to repack it and try to use unpackbootimg to unpack it. But I always get the same problem:

After this I got this text in ecovery.fstab:

Code:

---

# mount point        fstype    device            [device2]
/boot      mtd        boot
/cache      yaffs2      cache
/data      yaffs2      userdata
/misc      mtd        misc
/recovery  mtd        recovery
/sdcard    vfat        /dev/block/mmcblk0p1        /dev/block/mmcblk0
/system    yaffs2      system
/sd-ext    ext4        /dev/block/mmcblk0p2

Also i got this text using one of the kitchens(I found it in unpack folder)

Code:
