Hi. I got a Moto Maxx with Android Marshmallow (Telcel carrier).
After trying several roms, I decided to go back to stock, since I couldn't find a Marshmallow rom, I decided to update from 4.4. I installed "Mexico Retail Stock Kitkat /// RETLA_XT1225_4.4.4_KXG21.50-9_cid12_subsidy-DEFAULT_CFC.xml.zip" from this thread. Everything went fine, although I lost the custom recovery during the process.
Then, from the software updater option on the phone, I updated to Lollipop. Unfortunately, it didn't updated. Instead, I got a bricked phone. It didn't turned on.
In order to recover it. I followed this guide. The phone turned on again, and now I am stuck on an "empty" bootloader. The upper half of the screen only shows "Start", similar to the picture from the guide.
But I can't flash any stock rom. It seems by doing the steps of that guide, I re-locked my phone. I can't unlock it because, while I know my unlock bootloader code, mfastboot tells me I must enable "Enable OEM Unlock" in the developer settings (which I can't reach).
Trying to flash any stock rom gives me the following errors:

Why do people relock their bootloader?
With an unlocked bootloader you can flash other region images, if necessary, like Brazil. With locked bootloader your need Mexico. Your may even need your carrier firmware.

It wasn't my intention. The phone bricked, and in order to return to bootloader I followed that guide. It worked but it seems that during the process it locked the phone.
But you went from Marshmallow 6.0.1 back to Lollipop 5.0.2. You can't do that unless you omit gpt.bin in your flash commands. Otherwise you will get bootloop or brick your phone.
I assume at one time you had stock Marshmallow on the phone before trying custom ROMs? Or at the least, probably had flashed Marshmallow radio and bootloader?
With unlocked bootloader you can downgrade back to Lollipop or Kitkat, but you need to omit gpt.bin.
I would also omit recovery.img, to keep TWRP.

See this thread, but you'll need your region firmware.

Yes, as I said. The phone had Stock Marshmallow. I unlocked my bootloader, I tried custom roms, tried TWRP, I even could go back to stock KitKat (by omitting gpt.bin)
The problem came when I accepted to update to OTA Lollipop. The phone bricked; the screen didn't turned on. And while I found a guide that could unbrick the phone, I ended without recovery and with a relocked phone.

Because while you had downgraded to Kitkat, but you still had Marshmallow bootloader. You can't take OTA, because it will install bootloader and you cannot downgrade bootloader.
Have we discussed this before, because someone else did EXACTLY the same thing. Downgraded to Kitkat, then tried to take Lollipop OTA --which tries to install Lollipop bootloader!

Bootloader unlocking may resolve this. Try to not flash motoboot.img (Bootloader) - as it is dangerous and not even necessary.

you can not flash motoboot and a partition table from an older firmware if you already have a newer one i think (downgrade)

Hello!
I tried to make a downgrade of my XT1039 from Lolipop to Kit Kat.
My XT1039 bootloader is unlock (I have status3 in the fastboot menu) but when I try to flash the kit kat stock rom I see this:
writing 'partition' ...
(bootloader) Preflash validation failed
FAILED (remote failure)
finished. total time: 0.352s
I am not an expert but I think that from this point the rest of commands are not applied. After finishing the flash I reboot the device and it get's stuck in the bootanimation.
I don't know what to do. I red that is not possible to recover if the device was already updated to Lolipop but I am not sure. Should I try a Cyanogen firmware?
Any advice please?
Thanks you so much
This is a dangerous way to downgrade to KitKat. People have dead phones by flashing an older Bootloader.
You can safely flash one of these Stock KitKat ROMs: http://forum.xda-developers.com/moto-g/4g-development/rom-stock-motorola-4g-kitkat-rom-t3160127
If you choose an Untouched ROM - Do not accept OTA Updates. Such updates are disabled in the Optimized ROMs.
OK, thak you very much.
So my Moto 4g has freeze and reboot during the last official lollipop update and now my phone is unable to boot
I try to reflash a stock rom using fastboot mode (and mflashtool) but I got errors

After searching on xda forum it seems that the bootloader is locked so I'v try to use motorola's website to get the unlocked code (https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-a) but I'v always get the error "Your device does not qualify for bootloader unlocking"
I've try to remove place and using the Unlock Data Scrub Tool but always the same issue.
As my phone is unable to boot is there anyway to unbrick it ? Maybe and official tool able to flash with locked bootloader or something ?
I have a bricked moto g turbo which is locked so i cant flash firmware files i tried getting bootloader unlock code but a error shows up to tick allow bootloader unlock in developer options but i can't turn on my phone so I cant enable that option. please help
You don't need to be unlocked to flash factory firmware. Just go to http://forum.xda-developers.com/showthread.php?t=3169639 and get the correct firmware and follow the instructions in http://forum.xda-developers.com/showthread.php?t=3187750 and flash your device.
Bootloader unlock is only needed for downgrading, root, and flashing custom ROMs and recovery. It is not needed to flash a full factory image that is the same or newer.
And for the record, if OEM Unlocking is not enabled, the bootloader cannot be unlocked.

Hi i have the same error. But my problem is with the módem. I cant take signal. I try flash the original rom and don't work
Do you have the log file?
My moto g (xt1032) was running smoothly on Lollipop 5.1, Magisk rooted, until some apps kept crashing so I decided to reboot the phone (Used to fix the issue) but after booting the screen went blank, nothing showing, the only thing that shows was "Turn off" when i hold the power button, so I decided to boot into TWRP (Bootloader was Unlocked) and flash a 5.1 ROM that I used to successfully flash and work, but as soon as it finished and i press reboot, the screen goes black, no boot logo or anything, it only boots on the "Locked" bootloader.
Now the bootloader is showing version 41.1A . I tried to flash the firmware stock image that I used to flash before(GPE 5.1), i keep getting the same errors:
