Basically, I tried to flash the latest 5.1 image but unsuccessfully as the system.img wasn't extracted. For some reason I locked the bootloader and now I can't boot into a working system, and I can't reflash anything as the bootloader is locked. When attempting to unlock, it is telling me to go into dev settings to allow unlock.
Is there anything I can do?
Few threads about this today. Seems a regular user error. Can't think of a fix right now..

Can't be done.
Have the same problem and try to solve it with Motorola. No luck at the moment.

Can't. Boot loader is locked and requires a setting in android to be changed but android can't boot. Catch 22

Are you positive? I just flashed a Nexus 7 from 5.0.2 to 4.4.4 with fastboot. fastboot oem unlock worked without checking that box.

Damn, that's really lame...
Wow this craps really ticking me off with this update and all. I have been rooting modding for years and every damn time I get a device that uses fastboot I get nothing but trouble. I hard bricked three devices in the past with fastboot and it seems over the years fastboot hasn't gotten any better or easier. What a shame I love the nexus 6 but I'm seriously starting to reconsider and going back to the good old Odin devices.
I'm an idiot.
I made the mistake of trying to update my Nexus 6 (Stock 5.0 encrypted, rooted, Xposed) while talking to AT&T customer service on my other phone. Distracted flashing is a bad idea. I am sure I made SEVERAL mistakes.
I too was trying to flash the new 5.1 image and got an error when running ./flash-all.sh (I'm on a Macbook). Friend suggested I try to do it by flashing the boot.img recovery.img and then system.img manually. Got the boot to flash. Recovery flashed. System failed. Unfortunately I have closed the terminal windows and don't have the errors anymore. When it failed it said something about insufficient space. So (I'm assuming this is where I f**ked up) I hit start from the boot loader screen to boot into the system and delete some things even though I had plenty of space (over 20gb). It booted fine. When I went to reboot into bootloader, I accidentally selected recovery. It booted back into TWRP which confused me. I thought best bet would be to wipe the device and start over fresh. I wiped everything and booted back into bootloader... blackness. Now I have no response from the device at all. Nothing. No response from the power button. Nothing when I plug to a charger. Just blackness. Just a pretty, 2 day old Nexus 6 (warranty replacement from T-Mobile on Tuesday).
You wiped the boot partition too? Ouch...
Last time I did that, it was with my Nook Color. Thankfully that was able to boot from SD cards...
I have a similar problem with another Nexus 7 right now. Flash went corrupt, won't boot at all. No bootloader, no Google logo, nothing.
My only hope is that the device still talks to the computer, it shows up as a Qualcomm device under Ports in Windows Dev Manager. QPST picks it up and says it's in download mode. If I can source the hex files to flash, I think I can bring it back. I'm only sharing that because it might be your only hope too. Godspeed, sir.

lol, whats so hard with fastboot? fastboot oem unlock is rocket science? how about fastboot flash recovery recname.img? only way to hardbrick with fastboot is to flaah something to your device that doesnt belong there, or flash something into the wrong partition. how did you "hard brick" with fastboot???

The problem is that bootloader got relocked, and the OP is unable to get to the setting to enable oem unlock. Fastboot is errors out saying to Check "Allow OEM unlock", and FAILED (remote failure).
I would find it hard to believe that there is no solution to this. With all the bright minds here on XDA, I'm sure it can be figured out. The unlock setting must be stored somewhere, and it should be accessible.
When I first got my Nexus 6, I booted into the bootloader right after taking it out of the box (i.e., without booting into Android), and I was able to unlock the bootloader without having checked "Allow OEM unlock" in developer options. This could mean that the setting could potentially be located in /data somewhere.
OP, have you tried a factory reset in recovery? Have you tried playing around with the other bootloader menu items (e.g., "Factory", etc.)?

Thank you for taking a look at my post. I have tried all the options in the bootloader menu with no dice. Things aren't looking promising for me...
You're all using the newest fastboot?
flash the factory img
edit.. nevermind, i see ive already said that
I have a rather odd issue. I've been using the M preview, and after I rooted it, it restarted on me randomly. Anyway, I now have a fresh update to 5.1.1 from stock 5.1. My bootloader is re-locked, the bootloader version is matched to the proper system version, the stock recovery is in place. There is just one problem. Whenever I try to turn off the phone, restart it, enter recovery from android, connect it to a pc, or any other task that takes me out of android, it always boots to the bootloader and I have to choose it from there. There doesn't seem to be any issue getting to anything, it's just I can't change anything about the bootloader no matter what I do. I've been there and back again with unlocking, re-flashing and even now taking a full stock ota from a locked BL. I'm really stuck and could use some help. In the meantime, I'll keep trying and update if I can get anywhere with it. Thanks for reading!
Perhaps something is going on with your volume rocker. Does your volume rocker function normally? Maybe you have a case that could put some pressure on the volume rocker?
Actually, my problem was that the fb_mode_set was enabled, which will always boot into it. It's a stock precaution for updates. The solution was to enable fb_mode_clear, which returned the phone to booting normally. I hope if anyone gets into this situation down the road, this helps them out.

+1 yes please.
Sure. I clean flashed M and rooted it. It randomly rebooted twice on me when I tried to get a script to access root. After that, it was a bootloop at the regular startup screen. So, I entered into TWRP next, it started flashing. The only thing to do was to get into bootloader and reflash via fastboot, so that's what I did. I knew that I could downgrade the BL because it's a preview, but that wasn't my intention at the time. I took the google image of LYZ28E and flashed that, including the bootloader, fresh. Everything worked fine, except that the bootloader was now the first startup screen no matter what I did. I even downgraded to .08, which is as far back as you can go on 5.1! It didn't matter. BL was always the first screen up. So today, I started looking at the configuration of the BL. It seems that there is a safety protocol built into the BL that switches on when an unexpected error occurs, or when the BL is downgraded. It's there for things like firmware updates, etc. so that you don't end up with mismatches, which could potentially brick the phone. It makes sense, actually. Since I rolled back, it just switched on. I just wish there had been a little more literature on fastboot oem commands and their uses, it would have made for quite an easier time with this. Anyway, if you find yourself always starting up at the BL, try fastboot oem fb_mode_clear, which will disable the safety loop, and it should boot regularly. Again, I hope this helps, and if anyone has any questions, feel free to shoot me a message.
Edit: The entire process (TL;DR version)
1. Enter fastboot mode (if it's not already up)
2. Connect your phone to your pc
3. Open terminal
4. Type "fastboot oem fb_mode_clear"
5. Restart phone. It should now boot regularly.

Hi! I know I am a bit late to reply but for me the "fastboot oem fb_mode_clear" did not do the trick.
I started to play around with the commands and I finally got the alternative. This one did fix the issue for me, and for anyone whose phone did not get fixed by Mike's method, try this--
do steps 1,2,3 for Mike's method and on the 4th step use "fastboot oem fb_mode_clear system" instead of just "fastboot oem fb_mode_clear".

Hello
I recently got my mi5 after ordering from aliexpress and not a big fan of MIUI and wanting the cyanogenmod experience I applied for opening up the bootloader.
Today I recieved message that the request was granted and i happily started the progress with opening up the bootloader via the miflashunlock tool.
When I used the tool it gave me a message in lines of "No need to unlock this device" So i thought " Ok, maybe the seller had to unlock the bootloader to flash the global ROM or whatever.
I proceeed to flash TWRP and it flashed fine, so my bootloader must obviously have been open all the time?
Then I did a full wipe, instralled CM13 and opengapps and rebooted.
Now the trouble started.
All I boot into is a black screen, nothing happens.
If I try to boot into recovery I get a black screen.
I CAN boot to fastboot
So i go back to fastboot to check bootloader status.
(bootloader) Device tampered: false
(bootloader) Device unlocked: false
(bootloader) Device critical unlocked: false
(bootloader) Charger screen enabled: false
(bootloader) Display panel:
How can this happen? How the hell can flashing CM lock my bootloader? I never checked the bootloader in fastboot before this, but since I was able to flash TWRP I must have had an open bootloader.
I have tried to flash different ROMS via the MiFlash tool and it gives me message that the devices is locked (duh!)
I have tried to open the bootloader via the unlock tool but it says that the currenct account is different from the account info on the device. Not very strange since I installed CM13...
I have tried to both flash and boot into TWRP via fastboot but I can't do this since device is locked...
Is my only option to try this
http://en.miui.com/thread-299790-1-1.html
Or can i just throw the phone in the bin after three days and buy a new phone from another company that values openess a little more?
---------------
Booting to EDL-mode with this suggestion:
http://forum.xda-developers.com/redmi-note-3/how-to/guide-reboot-to-edl-mode-fastboot-test-t3398718
After this you can flash whatever rom you like with the miflash tool
I still end up in the same situation when trying to flash CM13
Phone boots to black screen, I boot back to fastboot and phone is locked gain.
But this is something I can try to figure out on my own
Just an update so if anyone else who ends up in my situation searches forums they might find answer here.
Every time i flash CM13 the same thing happens. Bootloader gets locked and phone can only start in fastboot.
I tried installing RessurectionRemix instead and it worked straight away.
Why the hell this happens I have no clue, but this some of you geniouses maybe knows.
Right now I really don't care since RR works just fine for me
any solution ? I have the same problem
I was gifted a Nexus 6 after my 5X died. As far as I know the device has never been OEM unlocked, much less flashed with anything. I've unlocked developer options and allowed USB debugging and OEM unlock but when I try to use power+Vol(-) to get into fastboot mode nothing happens, the screen is just black. When I bridged the device using ADB I could see the serial number and tried using the boot into recovery mode command and it rebooted to the same black screen. When I used fastboot commands on the black screen I could see the device and tried running fastboot oem unlock, it did something but wasn't successful in unlocking it. I'm not prepared to just start running fastboot commands blind like that without being able to see what's happening on the device's screen.
It's a curious problem, has anyone ever heard of it happening before? I can't find anything similar when I google it.
All I really want to do is clear the Dalvik cache and flash the latest factory image because currently, even after doing a factory reset, the device is very slow and laggy.
Is there anyway I could clear all the caches etc without going into fastboot mode or does anyone know of any fixes I could use so I can see the recovery menu?
If you boot to bootloader mode, then "fastboot boot <TWRP.img>" you might be able run twrp on your pc and clear caches. If it works, I'd consider factory resetting. You can get twrp here: https://dl.twrp.me/shamu/
I have considered that. But that requires OEM unlock, no? I still haven't managed to unlock it yet. The first time I tried, I said yes to unlock (it involves using the rocker to select a response, which I can't see the options for) but in the command window it said it failed (can't remember the error message though). I was going to try again today but because I couldn't see the options when I tried it said I'd cancelled the operation and I was too scared to try again in case something went wrong.
But, do you think I should try the fastboot oem unlock command again? I definitely need OEM unlock to install TWRP, right?

To install twrp yes, you need an unlocked bootloader. This doesn't install twrp on the device. I believe it should work. It certainly shouldn't hurt. I've been unlocked since the N6 came out so I can't double check for you.
If it doesn't work, I'd be a bit inclined to just flash a factory image thus ensuring everything is stock and current. You might want to wait for others to chime in, but it's what I would do.
You may consider downloading Nexus Root Toolkit, works like a charm : ).
I can't just flash the stock bootloader without OEM unlock, right?

Correct, you need to be unlocked to flash a factory image, that includes the bootloader. See Google's instructions. Don't get confused by the "fastboot oem unlock"
vrs "fastboot flashing unlock" we are an older device and use oem unlock. The other is for the 6P and newer devices.

Successfully unlocked. TWRP didn't help, still can't see the bootloader menu to access the recovery. I'm flashing the factory image now, hopefully a new bootloader will fix it. If not, is there anyway to clear the Dalvik cache using fastboot commands now the phone is unlocked?
UPDATE
Still a black screen even with a new bootloader flash. I'm assuming now this must be a hardware problem

I think the command is "fastboot erase cache". Also, unlocking will have wiped the device.

Why not just flash the entire factory image you got the bootloader from? What can it hurt? It would be really odd for this to be hardware if you can boot into the ROM and the screen works.
Hi guys,
Accidentally, im locked the bootloader of my moto z3 play and i cant boot because a previous bad installation that results in a bootloop.
I cant unlock from fastboot because the acctual system is new but unbootable (usb debugging and oem unlock disable by default...
I saw that there is some toolkits for many brands and models to fix this...
Will there be any for moto z3 play? or any other way to fix this brick?
I can access fastboot and stock recovery... Can i flash anything from adb sideload?
ty in advance

I have tried many times flash stock 9.0 firmware, but most part of lines out are permission denied (cause of flashing locked, i guess...)
After try flash, i get only bootloop and stock recovery.
I even already try apply update from adb sideloa to twrp or cwm but doesnt work (((
Plus, i try TOO boot on edl mode to use blank flash but doenst work, going to fastboot reason qcom boot failed ! ((((((((
I suppose can reflash the firmware with flashing locked? I have tried one of these beckham 9.0... I confess that not tried all of them.

Unlocking your Bootloader, you know where you enter that long code from the email that Motorola sent you.
I say this because sometimes people think, unlocking in the Dev-options, is actually unlocking the BL, when it's not.
Nor is a carrier unlock the same thing.
Your bootloader sounds locked from your Description of "access denied" errors.
I just want you to clearify that you are actually unlocked.

Although you're on Z3, this problem is generic. Ask in the Z2 forum, as they are more active. I also think the G-series (or other popular Moto phones) forums could help you with this.
Can you get to the recovery menu, and wipe factory reset (BL->recovery, up+pwr, Wipe/Factory restore)?
?

Ty for the advice... I will do that.
Yea, i can wipe data/factory reset, but its the same. Bootloop until stuck to "fastboot reason: fall-through from normal boot mode."
I've read about this scenario for months on several different model forums and I imagine my best chance is to use the blankflash in edl mode but i can't boot into edl mode. Wherever I connect it is always recognized as a Motorola PCS or Motorola ADB device. I'm thinking of buying the deep flash cable and see if it works ...
$ fastboot getvar current-slot
//Getting and setting the slot should not cause any harm, but you never know.
$ fastboot --set-active=<a/b - whichever "current-slot" isn't.>
$ fastboot reboot
EDIT0:
In addition, you should plan ahead if you do get in. Like doing everything it takes to allow you to unlock/flash (adb).
You don't want to miss anything critical and screw up that other slot too.

To everyone who is having this problem, just run the command multiple times in a row and it works! I don't know why, but just running it a few times in a row (I had to do like 9 times) gave me the unlock code.
Same thing for applying the code after getting it from Moto. Had to do it like 9 times in a row again, but it worked.
