[NEED HELP] Partition of recovery for Zenfone 5 ( CM 12.1)

I am a mid type of developer certified by me :cowboy:
My Zenfone 5 is hard-bricked and I tried everything to enter fastboot. iSoc and xfstk downloader showing error or refusing to accept my phone.
:cowboy: But luckily I can boot the phone in CyanogenMOd.
So I was trying to flash the recovery via terminal
Upper part can be ignored.
Command lines that doesn't work:

Code:

---

$ su
# flash_image recovery /sdcard/recovery.img

---

Optional I have tried

Code:

---

$ su

---

Code:

---

# dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p18

---

So the output was

Code:

---

29919+0 records in
29919+0 records out
15318521 bytes transferred in 0.342 secs (35459555 bytes/sec)

---

After that I have tried to reboot into recovery with

Code:

---

root@a500cg:/ # reboot recovery

---

Well. The phone doesn't reboot into recovery. What I can guess is the partition mmcblk0p18 was wrong.
I tried the command

Code:

---

mount

---

to get the proper answer from the device. It was too hard to get the answer or I am junior on that.
So, can anyone give me the proper partition?
