XT1575 stuck in bootloop, bootloader is locked, how do I fix my phone?

This phone has not been rooted or unlocked, I was running official MM OTA when suddenly last night it stopped booting. The Moto logo appears and then it goes to black and stays there for eternity while draining battery. I tried going into recovery mode and wiping cache + factory reset, but it didn't help. The "restore-to-stock" tool floating around the internet fails as well:

If I attempt to unlock the bootloader I get '(bootloader) Check 'Allow OEM Unlock' in Developer Options.' - which I can't do since the phone is bricked.
What can I do?

If you are not rooted or unlocked, time to take it to Motorola... Call em!

This is my only option then? I was hoping for something faster, but if that's the only option I'll take it.

Problem was solved by flashing the 6.0 stock firmware found here!!!

I'm in the same exact boat as you. I tried flashing everything under Android 6.0 on that page but no luck. Mine still bootloops. Exactly how did you do it? Thanks

Currently using last Resurrection Remix from Vatsal that have multi window but not floating windows
One off topic more:

No need to be sorry for off topic questions !
About the rom , i am not to sure about finding a rom with floating windows , but i would like that aswell !
Also , about using a european device in a different location, this is probably due to different network bands. I would NOT reccomend you flash another models modem, as this could hard brick your phone .
I foyu have any other questions, dont hesitate to ask !

I want to downgrade from stock mm(not rooted) to LP, possible?

Using my tool , yes ! . Remember not to accept ota tho

How are you doing the downgrade without having the bootloader unlocked???
Also, is this flashing EVERYTHING, including the bootloader and partition table, or is this just a tool to perform the "normal" downgrade of flashing a factory firmware image and skipping gpt.bin and bootloader.img?

This tool flashes SIGNED images, which means it does not need bootloader unlock. Also , it skips gpt.bin and bootloader.img . It is a normal downgrade, but i made this tool for people who dont want to risk bricking their phones typing the wrong command or accidentally flashing gpt.bin or bootloader.img

So if I use fastboot and flash a lp I just need to skip those 2 files right?

Downgrading from Rooted Stock MM
I have the XT1541 rooted on stock MM, can i downgrade to stock lollipop without bricking the phone ?

No need to use fastboot if you trust my programming . but yes , skip gpt.bin and bootloader.IMG and you will be fine my program automatically does that

Downgrade using fastboot it's not possible without unlocked bootloader, that's why I think it didn't work.

Device didn't start successfully. Bootloader issue?

So my moto G5 plus has had a problem. I was on stock oreo and it just crashed one day prompting "Your device didn't start up successfully". So I repaired it using the Lenovo software repair assistant and it worked quite perfectly. Now that I had a reset I thought of trying Pixel Experience [AOSP & CAF] ROM and flashed it.
It crashed again and now Lenovo software repair assistant is not able to repair it. Any particular reason? I had USB debugging on and OEM set to unlock when this ROM was working fine. I downloaded the stock ROM repair assistant suggested and tried fastboot way but it also didn't work. There was always remote failure.
Also, adb isn't detecting my device. fastboot is detecting though. here are some details:

I also trying getting the unlock key through fastboot. While I got the key, I was not able to unlock it (remote failure). Is there a solution? Any other details required from my side?
Fair warning: I'm so not a pro at this (clearly). I already ordered a new phone but the feel that I'm not able to get a solution from hours and hours of browsing xda is just disheartening. I refuse to give up on this one. Too many good memories associated with it

Well if you were on pixel experience then your bootloader is already unlocked so no need to do that. The fb log shows security version downgrade which happens when you try to flash an older firmware. Try the getvar command and it should show some more details and then just download the correct firmware. Does your twrp work?

Exactly. Grab the latest firmware 8.1.0_OPS28.85-17-6-2 (February security patch) and flash it. There's no newer stock firmware so a downgrade isn't possible

I can't get pass the boot screen. It just says device didn't start successfully. I'll try the getvar and will post again. I can't even reboot the phone or the bootlocker using fastboot.

Can't flash rom, stuck in TWRP recovery

I've had my G4+ rooted for quite a while and i need to format it so my mom can have it since I recently changed to a OnePlus 6T.
I tried to use the factory reset from the settings (seems like it was a big mistake on my part) and it didn't work, so I'm now trying to flash a stock rom through adb (I'd done this before), but I don't know what I need to do at this point, I'm at a loss, I even tried the commands to flash the rom and it seems to copy the system files but some stuff fails in the process.. I don't know what to do, did I just brick my device? please help
In case that helps, I have TWRP installed
And I think this might help, I personally don't know what to do with this info but this is what the command prompt throws back at me when trying to flash the custom rom while in bootloader mode:

Also, I tried wiping system, data, cache and dalvik-cache and here's what TWRP says: TWRP Errors
I get similar errors when trying to install my stock zip (from the external sd, I don't have an OTG cable right now so I copied to the sd card)

Is it possible the bootloader was re-locked with fastboot?
What's the ROM version you're trying to flash? Assuming TWRP hasn't been replaced by stock recovery and you can still load it, it would be interesting to know what kind of errors happen if you tried a TWRP flashable ROM instead of a fastboot ROM. Use the phone's internal storage (/sdcard directory) and avoid using an external SD card. But first see if you can both format and wipe in TWRP without errors.
You don't need an OTG cable for any of this. To simplify trouble shooting, eliminate the external SD card even if temporarily.

I'm trying to flash a stock ROM from this thread: http://forum.xda-developers.com/moto-x-play/general/official-stock-firmwares-added-xt1562-t3195364.
I'm still using TWRP, it wasn't replaced by stock fortunately. I'll download one or two flashable roms and see if that works.
Also, just tried to go through the process of unlocking the bootloader (in case it was re-locked as you say), and when putting the unique key and all, it says:
Code:
(bootloader) invalid boot state
And something I missed to mention now that I think about it, upon booting the phone it doesn't show the usual unlocked bootloader warning, instead its all black and it just says: "N/A" literally.

Now, upon trying to flash a TWRP flashable ROM, specifically "AFH" from the Nougat 7.0 section of this thread, I got the following:

I'm curious why you installed Moto X Play firmware to a G4 Plus. Or was the URL above a mistake and you meant this one?

That error indicates your bootloader is already unlocked. Flashing errors probably mean you're attempting to flash outdated firmware which sometimes causes problems with Motorola phones, so best to use the same or newer firmware than what was previously installed. See what happens with Oreo.
I suggest starting from scratch as cleanly as possible. I would even re-flash TWRP (official for G4 athene) for extra measure. And note the TWRP instructions about rebooting back into TWRP before flashing your Android ROM to avoid having to repeat installing TWRP. Also, the /system partition needs to be read-only if and when TWRP prompts you about it.
Format and wipe as described here: https://andi34.github.io/faq/faq_twrp.html
Then with the phone in fastboot mode and connected to your PC, flash the latest fastboot 8.1.0 ROM which will replace TWRP with stock recovery. If Android starts and runs normally after that, you should be able to re-lock the bootloader and hand it off to your mom.

You'll see the N/A notice on the boot screen when booting into recovery or a custom ROM is booting. Once stock is running N/A should go away.

Oh god, I had been using the wrong rom all this time LOL, but it was working, I mean, before all of this I had flashed that x play stock rom on the g4 plus and it was working without a problem for some reason..

Alright, so I reflashed TWRP, did the whole format and wipe thing: Format results Wipe results
I'm downloading the 8.0 image from the stock thread you linked me but its going to take a while, the servers seem to be very slow. In the meantime i tried flashing the twrp-flashable one I downloaded earlier: Image 1 Image 2 Image 3
It would seem it went okay, but I rebooted and nothing changed, so I tried flashing the X Play image i had as I had done before, but I still got errors in the process and it didn't work:

When I'm able to download the stock g4 plus image from the thread i'll try with that one and post my results, but I still don't understand what's going on

First off, whether you're flashing stock or custom, you need to stick to firmware specifically for Moto G4/G4 Plus athene. Just because firmware from a different Moto booted your phone doesn't mean it's working. Ditto for TWRP so make sure you're using the official release for G4 athene. An unofficial fork of TWRP probably won't do any harm, but for trouble shooting a stock Android install, there's no reason to stray from official TWRP.

Verify that this ROM is version 8.1.0 build OPJ28.111-22 or the more recent build OPJ28.111-22-1. If the ROM is literally version 8.0 that's not right.
Based on your fastboot errors, I'm wondering at this point if partitions have been mangled and even the correct firmware isn't going to flash successfully. Even if the phone boots and everything appears well at first glance, you could find out something is terribly wrong. Like the radio not working because EFS partitions (IMEI) are messed up.
Right now I'm not sure how to advise. I'm tempted to say "blankflash" but I don't think you're there yet because the phone is starting and you can load recovery. Let's hope somebody with more experience chimes in.
For now I suggest disregarding TWRP flashable ROMs and plan on getting through this with adb and fastboot.

I decided to give it another try, from the start:
Formatted data, then dalvik + system + cache, no problems, no red messages or anything lol
Then, reflashing TWRP:

Now, it says ID: bad key instead of ID: N/A, and there's the android mascot with its belly open saying: No command.
So yeah, didn't work.. I guess I'll look into the blankflash process but I have never done that before
EDIT: weird af thing just happened, I started the blankflash.bat from the guide while I was in fastboot but it was kinda stuck in "waiting for device" so i decided to close and reboot, and now it seems to be loading with the moto and lenovo logos... Now it seems to be working properly lol, this feels weird

After a clean install like this the first boot-up can take abnormally long. You probably just needed to wait it out. So is the phone starting and running now?
TWRP's output appears scary at first but looks like it flashed normally. All those "not found" messages during the ROM flash were followed by a bunch of "OKAY" messages. And I see that you flashed recovery.img which overwrote TWRP, so you must have seen the Android mascot in bootloader mode at some point during a reboot. All good!
If the phone is booting normally with stock recovery installed, you're ready to re-lock the bootloader if that's what you want. When the bootloader is locked the N/A and/or bad key notice will disappear along with Moto's unlocked bootloader screen. (I had it wrong in my other post; "bad key" is displayed when booting custom ROMs and custom recovery, where "N/A" is a normal part of the unlocked bootloader screen.)
Btw, blankflash is for devices that are hard bricked but you weren't even soft bricked (except for the brief time immediately after format). It's a last resort when phones play dead or partitions are scrambled. I'm glad to hear you stopped it before it did anything.

It seems to be working fine now, but there's an issue right now that I don't understand.
It only boots into the system if I go into the bootloader and restart from there. I had powered it off to save battery and powered it on right now, it goes straight to the android mascot thing with the belly open along with "No command" text. At that point I go to bootloader, click on "Start", then it boots up with the moto and lenovo logos and sounds.
From what I gather i'd say it isn't getting the command to boot up android when powering on, but no idea how to change that. I need to fix this because I know my mom will not be able to reproduce these steps in the case the phone powers off for whatever reason... Any ideas?
And also, thanks a lot for all of your help!!

Here in the forums there should be a lot of discussion about all kinds of devices with this same problem. Solutions vary depending on what caused it.
First try a couple of cold restarts. Power off and let the phone sit a few minutes before each start up. If the system still isn't booting try clearing Dalvik cache, power off and start back up. If you're still booting straight into the bootloader try flashing the ROM all over again. You don't need TWRP recovery for this, just flash while the phone is in bootloader mode.
By chance did you flash the 7.0 Nougat ROM? If so try 8.1.0 Oreo. There are bootloop issues with Moto phones that have been downgraded.

I've been using the 8.1.0 Oreo rom. Before all of this happened it used to have a 7.0.1 rom (which I noticed it was the X Play's rom after all this time lol) and never got updated.
I flashed TWRP to wipe Dalvik, did that and rebooted, it didn't help, and after that I couldn't reach TWRP recovery through bootloader. So then I re-flashed the rom (this time changing the recovery line to flash twrp instead of stock), but nothing changed, I still can't boot the phone without going through the bootloader, not even through TWRP's Reboot > system.
Sorry I took a while to answer back, its been a busy couple of days

Sorry, but right now I'm stumped on what to try next. You don't want to duplicate this post but you might consider starting a new post on the topic of flashing the wrong firmware. I still wonder how that may have affected your partitions.

If the fight is still on, maybe this post is pertinent to your problem installing stock Android to your G4 Plus.
