Can't re-lock bootloader!

So I tried CM13 and wanted to go back to everything official. So I restored the ROM from this place: http://ift.tt/1JwEtUb

...using this guide: http://ift.tt/1Yh5Hrw

Then I tried read the official Motorola guide to re-locking the bootloader: https://motorola-global-portal.custh...ecovery-images

Unfortunately it doesn't work. Using the guide, at the first step, I get this message:

Code:

---

fastboot flash partition gpt.bin
target reported max download size of 268435456 bytes
sending 'partition' (32 KB)...
OKAY [  0.004s]
writing 'partition'...
(bootloader) Preflash validation failed
FAILED (remote failure)
finished. total time: 0.141s

---

So I searched more on the web and ended up trying this:

Code:

---

fastboot oem lock

---

or

Code:

---

fastboot oem lock begin

---

and get this:

Code:

---

(bootloader) Please fully flash the signed build before locking phone!
OKAY [  0.023s]
finished. total time: 0.023s

---

I also found someone around here who said that by flashing the ROM his bootloader was locked again. That didn't work for me. I'm still getting this

Code:

---

"Device is UNLOCKED. Status Code: 3"

---

on the bootloader.

What can I do?
