I need advanced help: Problem with XT1068 bootloader. Read in detail the problem pls.

Thanks for your time trying to help me, I REALLY appreciate that

Well, before telling you the problem, here is my device info:

- Moto G 2nd GEN XT1068
- I was in Android 5.0.2 Stock
- Bootloader version 48.83(*)
- CID: 0x000C

The problem: A few days ago, with no reason (haven´t modified NOTHING at all), I turned on my device but it booted in bootloader mode... strange... so I just selected 'Normal powerup', after some seconds in the boot logo, it return to bootloader mode... always!.

Anyway, I siad: I just have to restore my firmware. Problem > I had not unlocked my device´s bootloader. Ok, I am just going to unlock (the same way as always) but, sometimes, when I enter this command mfastboot oem get_unlock_data I get this:

Code:

---

C:\Users\SebastianD\Desktop>mfastboot oem get_unlock_data
...
(bootloader) Failed to get unlock data, please try again!
FAILED (remote failure)
finished. total time: 5.008s

---

After many attempts I got my unlock data, then I did what I had to do: I went to Motorola Unlocking Website, entered my string, the code was sent to my e-mail (I did it with 2 e-mail accounts and got the same code), BUT! when I use the command mfastboot oem unlock UNIQUE_KEY I get, ALWAYS, this:

Code:

---

C:\Users\SebastianD\Desktop>mfastboot oem unlock [my_unlock_code]
...
(bootloader) Unlock code = [my_unlock_code]

(bootloader) unlock data invalid!
FAILED (remote failure)
finished. total time: 9.984s

I talked to Motorola service, but they say they do not have support for this because of their terms and stuff about the bootloader unlocking
This is freaking me out!
