Hello XDA,
Ok, so I'm going to try to explain the best I can. My roommate has a Nexus 6 (Project Fi if that matters). She went to install an update, although I'm not sure which one. She said she thinks it was "7 something". I'm assuming it was 7.1.1 since that is the one that I was last notified about on my phone and she said the notification appeared only a few days ago. After she installed it the phone was stuck in a bootloop (the spinning colored balls screen).
I Googled solutions and tried wiping system cache from recovery mode. That didn't work, so I asked if she had anything important on the phone and if I could do a factory reset. She said I could go ahead and do it, however that did not work either. So then I plugged the phone into my computer and fired up a terminal session to flash a factory image to the phone. I entered "fastboot oem unlock" so I could proceed . It came back with the "see developer options" message. Ok, cool, but I can't get into the settings app to enable OEM unlocking.
So since I did the factory reset and can't boot into the OS, is there any way to enable OEM unlocking from the bootloader? I'll keep looking for answers in the mean time.
Thanks in advanced.
EDIT:
Found a thread with the OP having similar issues. I tried "fastboot format cache" and "fastboot format userdata" which both failed with "Not allowed in locked state!". Even though I got the errors I tried (out of desperation) to boot to TWRP with "fastboot boot ~/Downloads/twrp-3.1.0-0-shamu.img" which failed with "FAILED (remote failure)".
EDIT2:
Tried downloading 7.1.1 OTA image and sideloading via "adb sideload shamu-ota.zip" from the bootloader recovery mode. Failed with "error: no devices/emulators found".
Sideload an OTA image. That should resolve the bootloop so you can enter Android to unlock the bootloader.

Thanks for the reply. I tried it and it failed with "no device found". The command "adb devices" gives me an empty list. Not even ????????.
If ADB isn't seeing the device you potentially have a hardware issue.
i got same problem.
no oem unlock cuz is in bootloop
locked
erasing
@luisq93: Yours is a different issue. The solution for you is to do...nothing.
The erase part of the factory reset MUST complete, or you may end up with unusable internal storage until an uninterrupted factory reset is completed. So all you can do is be patient.

like 2 month and half patient?
cuz the erasing changed language 2 months ago and nothing more... from italian to English, maybe i should just wait... thanks for the advice.
@luisq93: How long did you leave the N6 running the very first time the device started erasing? I'm willing to bet you only gave it a few minutes, became impatient, shut the device down to restart it and upon restarting encountered the erase mode again. Consequently you thought it bootlooped and put it in your drawer.
Until you let erase mode complete, every time the device boots it will immediately enter erase mode, because the erase must complete to avoid corrupting the internal storage. Erase mode, especially on an encrypted phone, may take a while. I had one instance on another of my devices take an hour.
So the solution to the erasing "bootloop" is to do nothing except plug the N6 into its charger and leave it alone.

I have a Nexus 6. I've been on build LMY47D. My storage was showing as 32GB when I have a 64GB version. I read this post for a fix. I did a fresh install of adb, checked the OEM unlock, removed security (PIN) and turned on USB debugging from developer settings. I used "adb reboot bootloader" to reboot to the bootloader and then typed the commands from the post I linked above:
fastboot format userdata
fastboot format cache
I was wanting to take the OTA update so I was planning on flashing the LRX22C image and wanted to make sure I was OEM unlocked so before rebooting I also did:
fastboot oem unlock
The result said:
<bootloader> device already unlocked!
FAILED <remote failure>
finished. total time 0.002s
I figured I was unlocked and essentially factory reset, so I entered:
fastboot reboot
It was on the spinning dots for about an hour. I read somebody with something similar rebooting after such a long time and everything being ok, so I tried it with no luck.
I can get boot to the bootloader. The lock is unlocked. When I try to go to recovery I just see the dead android with the red sign and exclamation. My PC no longer sees the phone, I think because I'm no longer in USB debugging? Is there any way to fix this? I've tried selecting "factory" from the bootloader, but get the same result--endless bootloop. Any help is appreciated!
EDIT: Thought I'd add, at the bottom of the bootloader screen it shows "Device is Unlocked. Status Code: 3"
EDIT 2: While waiting for feedback, I downloaded wugfresh's nexus toolkit and selected the softbrick/bootloop option. It's downloading a factory image atm, so we'll see how this goes.

When you see the dead android (recovery) just press volume up + power simultainiously and do a data factory reset, after that the phone should boot up fine.
PS: don`t use toolkits, they cause more harm then good if used by unexperienced users and experienced users don`t use it anyway

Thanks for your response. I actually tried pressing volume up + power simultaneously several while at recovery and nothing happened. After that I tried other key combinations, wondering if I got it wrong, and nothing happened with those either.
I ended up using the toolkit (before I saw your response) and my phone is back in business *HUGE sigh of relief*

FWIW: to enter the recovery menu in stock recovery, the combo is - press and hold power, and press and release volume up.
Well, I really did it this time. In my efforts of messing with the M Preview build and trying to eliminate the "verification failed" startup message I made the mistake of locking the bootloader. Now the phone will not boot into Android or into Recovery. I'm stuck in Bootloader and it won't let me "fastboot OEM unlock" the device because in order to do this you need to boot into Android and tick the box to allow OEM unlocking (which I also unticked before getting into this mess, like an idiot).
EDIT: Got it resolved!
In order to get into Recovery I had to use the following commands in the bootloader:
fastboot format cache
fastboot format userdata
After doing this I was able to boot into recovery. However, recovery showed 0MB available storage and wouldn't mount /data, which prevented me from installing anything. It also wouldn't allow me to copy anything to the SD card using Android File Transfer or ADB sideloading.
To solve this I went into "Wipe" while in recovery and did a full format (the one that requires you to type "yes" before proceeding"
After doing this and booting back into recovery, I had full storage space back and recovery was able to mount /data. At this point I just copy/pasted the 5.1.1 ROM onto the sdcard with Android File Transfer. Once installed, I flashed the ROM and it booted right up.
I then skipped through the setup to get to settings and in developer settings I ticked the box to allow OEM unlocking. After doing that, I booted back into the bootloader and used the fastboot command "fastboot oem unlock" to unlock the bootloader again.
Once that was done I was able to use fastboot commands to flash the M preview all over again.
Hopefully you don't find yourself in this mess, but if you do, I'm hoping the above solution works for you.

Is TWRP installed?
WAIT!!
I did the following:
- fastboot format cache
- fastboot format userdata
And the phone now boots into TWRP. It won't boot fully but it will boot into recovery. I'm trying to sideload a ROM now but I can't access the storage.
Edit: enabled ADB sideload so I can ADB push a ROM to the SD card to flash. Does anyone know the exact root folder name for the sd card to pusht he ROM to? Is it /data/media/?
I did something similar this past weekend while trying to do the 5.1.1 upgrade with the OTA files before the Factory images were available.
Try and use the WugFresh tool to wipe the cache and such, and try some of the other obvious settings in the tool.
It was late and I'm not 100% sure what I did but I do remember reflashing the LRX22C from the factory image using the tool. Everything I did was from the tool minus the 5.1 OTA that came through once I was able to get back into the device. From there I was able to unlock the bootloader again.
I was worried myself that I might have to send the phone back but I just kept trying, don't give up just yet. I've been told many times it's almost impossible to brick an android device now a days.
Good luck!

However, I was able to ADB push the ROM to the SDcard. But when I try and install the ROM it gives me a bunch of errors saying "unable to mount '/data'" and "unable to mount storage"

Assuming you tried ticking data in twrp mounts...
In twrp, try and format data again. If that fails, try to format it as another file system such as f2fs before formatting it back to ext4

Success!
TWRP was also reporting 0mb available storage. I went into Wipe and performed a full format. Booted back into recovery and storage was showingt he full amount again. I was then able to plug the phone in and enable MTP and drag/drop the 5.1.1 ROM onto the SD card. Just flashed it and it booted right up!
I'm going to update the OP with all this info just in case someone else runs into the issue and needs help.
Thanks for your help!

Hi,
I faced the same condition like you experienced, with some differences:
- the phone stuck in "Google" logo
- stock recovery is accessible from bootloader
- I am unable to mount sdcard or install rom from sd card, but could conduct adb sideload
However, am stuck with verifying update package showing :
E: footer is wrong
E: signature verification failed
any ideas what to do next?
================ edited- add below info on how I got stuck
So my N6 was still on 5.0 (has not been updated to 5.1). I decided to try the M preview. I downloaded the preview, and began the process as follows:
1. reboot into bootloader
2. fastboot oem unlock
3. flash-all (success on loading the bootloader and radio, but error on updating the image)
4. hence i followed to flash individually:
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot erase cache
fastboot flash cache cache.img
5. and comes the stupid thing ! --> fastboot oem lock (really really regret why I did this)
6. and then once reboot, it stuck in Google logo forever
However, I am still able to access:
- bootloader (fastboot recognize the device, but wouldn't allow me to fastboot oem unlock)
- able to go to stock recovery, and as mentioned above:
I am unable to mount sdcard or install rom from sd card, but could conduct adb sideload
However, am stuck with verifying update package showing :
E: footer is wrong
E: signature verification failed
I tried to adb sideload the M preview image and 5.1 LMY47I but both showing the above error....
hope you can shed some light on this...

A solution to what? Keep in mind your problem may be different from the OP's issue, so if you want people to help you it's necessary to provide plenty of information, such as what you were trying to do, how you tried to do it, and any other information that you believe may be useful.

OK What i was trying to do was to flash a stock recovery, i start it by running the flash-it all.bat file in the factory image zip, it changed the user interface of the bootloader after first reboot and and had an error for "archive: recovery.sig not found" (something like). the phone status shows Software Version: Modified and fastboot oem unlock dont give the confirmation.
and
now my phone wont even boot to the bootloader, everything turned black. please hellp!!!!:crying::crying:
If you can't even get into the bootloader (volume down and power) you may have to have the device serviced. Do you get a response when you type "adb devices"?

Maybe it just crashed at a black screen? Does a very long press of the power button (over 10 secs) cause it to react?
Or maybe the battery is empty? Try connecting the power supply for some time.
i did that but no response.

The very dead battery is a real possibility. The thing is, using the charger that came with the phone isn't going to help. If you think the battery being dead is a possibility, you would need to plug the phone into a USB port on a PC, that is a very slow charge. Leave it on there overnight then unplug and replug. If the led at the top of the screen lights or the battery icon shows on the screen, you have hope. At this point using the original charger should get the battery going again. In this case, plan on replacing the battery.

So this morning i tried this. Kingroot didn't complete the root, some error happened, i didn't mind since i was just testing to see if i could root my phone for the first time [i've never done it before and it seemed simple enough].
I quit the app, a bunch of errors showed up, one after the other [i didn't register what exactly the windows said, i'm pretty sure it was a google application that stopped working]. The phone turned itself off.
i booted it up again, and it showed me the AP Fastboot Flash Mode screen. i know this from previously doing a factory reset, so i tried doing it again. After it wiped all of my data and custom, i tried rebooting it.
it showed me the motorola icon, but a few seconds later, i was back at the fastboot screen. i'm pretty desperate right now since this is my only phone. i tried selecting the "normal powerup" command, it didn't work. this is my screen right now:
"hab check failed for boot
failed to validate boot image
fastboot reason: fall-through from normal boot mode
USB conected
hab check failed for boot
failed to validate boot image
boot up failed"
none of the other commands, aside from Recovery, work. it takes me to the no command screen and all of the known options once i use the power+volume up command: reboot system now, reboot to bootloader, apply update from ABD, etc.
sorry if this thread reads weird, i'm sort of freaking out right now and english isn't my main language. thanks in advance to anyone who might help!

If you have questions PM me I will try to help. I got the same problem on Monday and solved it yesterday.
Hey!
So i'm making this post after battling over 4 days with my friends old oneplus 3t.
All started maybe year ago when my friend asked me for help because his oneplus had suddenly gone into a bootloop kind of state (he told me that the phone was in his pocket working fine and when he tried to use it next time it started acting up.) Before i could even help him he had already bought new iphone, so the oneplus stayed in his drawer until last week when i remembered it and started to try to fix it.
So first thing that i noticed was this message "The dm-verity is not started in enforcing mode and may not work properly", the message eventually went away and i got to a recovery mode and thought that this is gonna be easy, hooked the phone to pc and started adb and tried to sideload the official rom from oneplus site, but everytime i tried it went to maybe 47 %or 66% and failed eventually. So i thought that ill try flashing original recovery.img, started fastboot and tried flashing and everytime "remote: Partition flashing is not allowed". Tried many times also oem unlock command and failed miserably, all i got was "remote: oem unlock is not allowed". Eventually trying every command from fastboot and adb i came to a conclusion that the device doesn't allow anything to be written to its storage (Tried of course flashing twrp, but same error).
Downloaded Oneplus 3T unbrick tool v3.0, and qualcomm drivers (turned windows driver signature off) everything went great and the green text came in oneplus unbrick tool and i proceeded to start the phone in excitement and the circling bootlogo started and it just stayed there, nothing, and after while shut down.
Things tried now:
-Sideloading (many times with different roms) no success.
-Fastboot (It recognizes the device everytime, but all other commands than "fastboot devices" end to an error"remote: something not allowed") no success
- Unbricktool v3.0 (Works like a charm everytime, but phone doesent still boot to os) no success
-recovery (wiped cache and all data many times) no success
My friend never flashed anything to this device, he doesn't even now how to do this kind of stuff.
Phone not dropped even once, is in a perfect condition and has all the original stickers even.
I have grown obsessed to fixing this phone, so any help is greatly appreciated :laugh:

I haven't personally ever had to use the unbrick tool, so I can't help too much with the core problem. But what I can say, is that the steps I've quoted above (trying to flash recovery partition, etc.) are going to fail by design, since the bootloader is locked. This is the very purpose of the locked bootloader. The expected result is "remote: not allowed".
And as far as I am aware, you have to have a working OS and have "OEM unlocking" first toggled on, in the phone Developer settings. Otherwise (again, by design) the "fastboot oem unlock" command is going to fail.
Spontaneous failure of the phone to boot to OS, and dm-verity warning, to me probably indicates the OS has become corrupt/damaged. The damage is showing as a change to the system, therefore the dm-verity warning. Normally, I would tell you to flash the stock recovery image. But of course you have already tried that. Probably difficult to determine for sure. but spontaneous failure, and failure to flash recovery image (multiple times) may indicate a hardware failure such as bad emmc.
Hi Guys,
My phone suddenly stuck at this screen since may :
Android Recovery
Xiaomi/jasmine/jasmine_sprout
9/PKQ1.180904.001/V10.0.9.0.PDIMIXM
user/release-keys
Use volume up/down and power.
Can't load Android system. Your data may be corrupt. If you continue to get this message, you may need to perform a factory data reset and erase all user data store on this device.
- Try again
- Factory data reset
If i press try again, sometime it will go to fastboot screen.
I can go into recovery mode here but i not sure which step i should do next.
Reboot system nowreboot to bootloader
apply update from ADB
apply update from sd CARD
wipe data/factory reset
Mount/sstem
view recovery logs
run graphics test
run locale test
power off
I'm not a very tech savvy person, i would really appreciate some help as i have data inside my phone which i need. So if possible i would like to retain the data.
I tried like EDL,fastboot,and flashing none seem to work. Of course I may be doing it wrong.
Can anyone guide me step by step I be happy to give an reward via paypal.
I'm so sorry bro.... 80% of times this means you lost your data.
Is the bootloader unlocked?

Thank you so much for replying.
Nope, but I can do EDL to unlock bootloader, I already disassemble the device a few times.
Just that every time I try to flash it , it give me some error. like Bluetooth error or the version error .
Which I watch thousand of video to work but it's doesn't help. Or maybe I just watched the wrong video
Ok tell me exactly what are you doing and where you have downloaded the rom.
If it's corrupted and you try to flash it you will lose the data... Was debug USB activated on developer settings?
My device died too. After the October update, he never came back. It is looped on the home screen written "Android One".
I've tried several tutorials, it accesses the FastBoot screen, but when trying to use MI Flash appears a Bluetooth error and does not proceed.
I've tried using the adb flashing unlock_critical command, but it fails too.
He didn't have the bootloader unlocked, I now have a large paperweight.:crying:
