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. 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
Hi, I wanted to flash the 5.1 update to my new Nexus 6.
I went all over the basic steps.
After I unlocked the bootloader I tried to flash the image with the flash-all command.
It failed, so I remembered maybe I forgot to click on USB debugging? (This confuses me because I think I shouldn't be able to unlock bootloader without this).
When I wanted to start android I locked it first, so I would unlock it afterwards and erase everything to start as new.
Whan I locked it, I could not unlock it again. I can't access Android, neither do anything else like factory reset nor Recovery Mode. I return to the bootloader as soon as I press anything.
There are red words at the top: AP Fastboot Flash Mode (Secure). Does this means anything?
Is there any way to force unlocking the bootloader? When I try it, the phone tells me to go to Developer Options but I can't access Android.
Please HELP! Is there any way to flash a rom or android again in locked state? Recovery?
Thanks for reading this and thinking about a solution! I really hope I won't be stuck forever in bootloader.
Uh oh... Were you trying to downgrade back to LRX22C from LMY47D so that you could upgrade to LMY47M, by any chance?
If so you might be fooked.
Actually no. I was trying to upgrade from 5.01 to 5.1. I'm really scared of having my Nexus 6 bricked. I can't do anything to unlock the bootloader. Maybe I could sideload a recovery? But do I need to be unlocked?

I already tried this solution, I think mine is a little different. At the end of the post it says to enter fastboot and restore with a factory image. I can't because I am not unlocked. In order to unlock my device I have to go to Developer Settings (it is the message when I use the OEM unlock command). but I can't access to Android. I am stuck in the bootloader but can run fastboot commands.

The solution that was posted should work, but you need to use RSD Lite in order to flash the factory image, not fastboot.
Read it over nice and slow again, because you are in panic mode right now, so take your time and you will get it back up and running with no problems.

Thanks! I've been reading a lot from this thread but I get something unusual as the other people are experiencing. When I try to flash partition gpt.bin I get (bootloader) Unlock before flashin.
It is kind of contradictory as this fix supposedly fixes flashing without unlocking. I don't know if it is a problem of drivers. My PC sees my N6 as Google Nexus Bootlader Interface. In the thread, the PC sees the device as "Bulk" or "Qualcomm ....... etc etc".
My panic mode isn't turning off. I may be missing something.

Now I've tried everything in that thread, when I was reading I thought flashing gpt.bin would be the solution but I can't do it, I can't flash it.. It says "Unlock before flashing". Supposedly flashing gpt.bin would allow me to flash without unlocking.

I agree because op is somehow confused.....fastboot has nothing to do with develope settings USB enabled
Yes it does. He flashed the factory images, then relocked (which defaults to disabled oem unlocking). But something failed (guessing possibly userdata failed). I would recommend fastboot formats userdata to perform a factory reset from the boot loader to see if you can get android to boot.

Here's the story. Got Google Fi package and Nexus 6 today. Decided I'd load Android M preview on Nexus 6. did all the fastboot stuff to get the developer preview installed, then while still in fastboot mode I installed TWRP, then locked fastboot, then rebooted into TWRP. Pushed ROM zip to /sdcard through adb, tried wiping everything failed. Tried flashing zip, everything failed. Decided to reboot. TWRP asked me if I wanted to install SuperSU, i chose to because I thought I might need it to get TWRP working. After rebooting got message "Your device has failed verification and may not work properly" then it powers off. I can boot into fastboot/recovery, but in recovery the touchscreen doesn't work so I can't do anything. Booting normally gives the failed verification message. Tried fastboot format userdata, which I believe is what caused the touchscreen to cease registering in TWRP.
Is there any way for me to recover this thing? Back when I had a Galaxy Nexus, and even with my S5, there's nothing really that can be done that would completely brick the thing. I'm pretty dumbfounded that a Nexus device would be so easily bricked...it's not like I don't have experience with this stuff, I've been rooting and developing Android apps for years.
I have a feeling I have to return the thing, but Amazon has no more stock, and if I buy directly from Google or Motorola I'll have to pay sales tax.
Any help is greatly appreciated.

Did you lock the bootloader just to be clear?
bricked? no, you just didnt read up in information properly. you relocked your bootloader. as of android 5.0, you have to enable unlocking the bootloader after you boot up in the developer section. since you relocked your bootloader before you checked if your device will boot, you can not unlick your bootloader again, which means you can not use twrp either. what you can try is using fastboot to wipe your cache and data. if that doesnt work, id try to get an rma.

If a device is unusable, without any way to recover it, it's essentially a paperweight, or bricked. So if my only option is an RMA, then it is bricked. I don't mean to sound rude or argumentative by the way... I appreciate your help. Just clarifying the semantics.

Also if you wait a little while after that message, you may be able to use adb commands again.

It says it will reboot in 5 seconds, but after 5 seconds the screen just goes blank. It appears the device is off, but maybe not.
Do you know what adb commands I would need to use to recover from this state?

technically, its not bricked, not yet anyways. as many people have fixed this issue using fastboot to wipe cache and data.
well, let it sit for a few minutes after the message, it may just boot normally. That verification message appears with M preview for many users.
you may also see HERE for another possible solution.
if adb is working, chances are pretty good its booting into android, in which case you wont need to do anything else, but let it boot (be patient, it can take several minutes), then retick the selection to allow oem unlock.

ADB works when I boot to TWRP, but when I try to boot normally, after the device will boot in 5 seconds message, the screen goes blank and adb does not work. I let it sit like that for more than 30 minutes. Curiously, when the screen goes blank my PC does chime indicating hardware has been attached.
Can you still get into twrp? If so just move a ROM over to it and flash that, enable OEM unlock restart and unlock boot loader...

If you have TWRP, boot to bootloader and use the following fastboot commands:
fastboot format userdata
fastboot format cache
Then boot to TWRP, connect to PC. Download a ROM to your PC and drag and drop in the root of internal storage. Then flash the ROM from TWRP, boot up, enable OEM unlock. Then boot back to bootloader and:
fastboot oem unlock
You should be good after that.

By all that, i've been searching online for a solution for days, without any luck...
So now im back with a phone that's oem locked and can't unlock it because i can't allow oem unlocking in developer settings, and can't do adb push because i do not have any recovery on the phone.

Can't you get to the bootloader and fastboot the stock google images? This is a N6, right?
@ktmom: He can get to the bootloader, but it's locked, which means fastboot is not an option. Worse, he apparently has no recovery installed so he can't sideload an OTA.

How can i make a running recovery on a pc?
Tried to search for it, but i cant find anything on it
Code:
fastboot boot recovery.img
The above command sends the device into recovery mode using an image stored on a PC's hard drive. From there the owner of the device can use the recovery just as if it were installed in the /recovery partition of the device's internal storage. Files that the owner of the device wishes to use are stored in the device's internal storage.
It won't help the OP however. An unlocked bootloader is one of the pre-requisites.
Cant boot up a live recovery either, because of tge locked bootloader...
Anyone got other ideas? Im really lost with this one
Contact Lenovorola and pay for the privilege of having your device serviced. You're totally screwed.
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.
