I have recently purchased Nexus 6P which has boot loop problem and I know that I could potentially fix this issue by side loading OTA image via adb or flashing full factory image via fastboot. Side loading has completed successfully, but it hasn't fixed boot loop issue. Also I cannot flash full factory image because OEM unlocking wasn't allowed.
Maybe someone knows how to allow OEM unlocking using fastboot? I will appreciate any help. Thanks in advance!

Not possible. If the bootloader is locked and you can't boot into Android OS to allow OEM unlocking, you won't be using fastboot. Any luck using stock recovery to factory reset after a sideload? FYI all data on the phone will be lost.

You mean by factory reset formatting cache and data from recovery options?
Also I'm currently on MTC20F/6.0.1 build. Maybe it is reasonable to sideload more recent version?

Yeah that's what I meant. Factory reset and cache wipe from stock recovery options. I guess it couldn't hurt to try sideloading 7.1.1.
It sort of sounds like the issue people had with the bugged versions of TWRP when restoring a backup, but the phone has stock recovery, right? I'll post a link to the thread where a bunch of people were collaborating to try to figure it out. You can search the thread to see if any suggestions help you out. I don't personally follow the thread, since I never had the issue and generally don't restore nandroid backups unless I absolutely have to. Usually if I need to restore I just plug into a PC and restore manually.

When did you purchase the phone?
Was it used before purchasing?
What version of Android was running on the phone when it bootlooped?
Does your phone boot upto Android colorful dots animation or boots upto Google logo only?
Please answer these questions to give us insight about your problem.

1. Yes, it was used previously by someone.
2. 6.0.1. I guess. This is the build version that is specified in the stock recovery.
3. Unfortunately only Google boot logo appear on device's screen.

Can you manually get the device into the bootloader? If so you should be able to flash the full factory image following the instructions on Google's image download page. The flash.bat.all command works even with a locked bootloader and even if USB debugging is not enabled. It saved me a few times when I was soft bricked and nothing else helped.

are you sure you can flash the factory img with a locked bootloader? I'm counting on this because I can flash rescue OTAs in recovery successfully but nothing changes after OTA sideload. I was hoping I can flash factory img but unfortunately my bootloader is locked.

Steps that I have done from stock recovery:
1. Wipe cache
2. Wipe data/ factory reset
3. Sideload 7.0 (angler-ota-nbd91k-32c2eac8) and the result is successful "script succeded: result was [1.000000]"
4. Wipe cache
5. Wipe data/ factory reset
6. Power off
7. Power on
Unfortunately boot loop persists and if I go back to recovery there is the same build version MTC20F (6.0.1).

For "fastboot oem unlock" command prompt returns "failed: remote: unknown command". I think this is because Google has changed such command to "fastboot flashing unlock", which gives me "failed: remote: oem unlock is not allowed". This because OEM unlocking hasn't been allowed from Developer Options by previous owner and now I cannot get there because of boot loop. Also have tried "flash-all.bat" from 7.0 latest factory image and on each step it returns error "failed: remote: device is locked. cannot flash images" and this is because of locked bootloader.
Possible solution?
In Stock recovery I have "Mount /system" option. Maybe someone can clarify what does it mean and could it potentially fix boot loop in some way? I have tried google for it, but unfortunately have no luck in finding information about this option.
Thanks in advance for any information!

Are you running the latest versions of ADB and Fastboot?
This sounds like an issue that would have been covered under warranty --for the original owner. Did you buy the phone knowing about the boot loop problem?

I think that they are the latest, because I'm an Android dev and I'm updating SDK with tools as soon as new version come in.

Yep, I have known that device has boot loop issue and it was selling as-is for repair. Also I have known that this issue could be fixed, so it was hit or miss. Now I think that this was a miss.
It's starting to look that way. You would think there would be a way to reformat the drive and start from scratch like a computer. Maybe someone with programming knowledge will find a fix for you. It's odd the owner didn't RMA the phone rather than sell it as is/not working. Huawei was even fixing phones with similar issues for free a couple months out of warranty.

You can go to this site to check if the device is still under warranty. I have read about them allowing RMA on 6Ps that were out of warranty so it's worth a try at least.

Sorry this is the site to check if phone is in warranty within the US. Other site was for India.

My Nexus 6P is stuck on the Android boot animation after installing the Android Beta OTA that came out today. I waited like 30 Minutes and nothing was happening so I tried Clearing Cache which did nothing then factory resetting, Clearing Cache & Even sideloading the OTA using ADB to no avail. My huge mistake was not having OEM Unlocking enabled so now I can't even flash stock android.. I know this is my fault for being so stupid but is there anything at all I can do to save my phone?

I'm in the exact same boat...hopefully something can be done, but I'm afraid we're idiots for not having checked OEM Unlocking. I've tried adb sideloading the OTA image, but as you said, with a locked bootloader, we've got nothing. Anybody have any ideas?
You might be able to use ADB to modify the OEM Unlock setting while booting.
Also, if you ever plan to mess with your OS, especially alpha/beta versions, always have your bootloader unlocked to prevent issues like this.
Use Fastboot boot [[[name of latest twrp]]].img (make sure the .img is in the adb folder on your pc) and then do a full system wipe (not just factory reset, but literally everything, internal and external -- access this from the advanced menu in twrp). That should boot you into the system so that you can enable oem unlocking, unlock the bootloader, and carry on like normal.

Can't boot twrp.img because the device is locked. Anything else I can do?
I had something similar like this happen, for my fix, all I did was boot to bootloader, cleared cache and then did a complete shutdown, do not just reboot, just rebooting, would go thru the boot loop, but a full power down allowed it to boot up normally. Not sure if it will help in your situation, but it's an easy try

No luck for me, unfortunately. Keep in mind that I tried to sideload the OTA.zip with a locked bootloader before doing this, so that may have made this process not work. For those who haven't tried to "fix" their failed installation like I did, give the cache clear a try first.
Apparently some people can use the fastboot format command while their bootloader is locked. You can try booting into the bootloader and issuing these commands. (THIS WILL WIPE YOUR ENTIRE DEVICE INCLUDING SDCARD/INTERNAL STORAGE. Of course, your device is now bricked, so I'm sure this is fine for you.)
Code:
fastboot format cache
fastboot format userdata

I have the latest preview build directly installed ota from Google. The phone just started bootlooping the other day for no apparent reason. I didn't have the developer options on or oem unlock enabled.
I can get to bootloader mode and recovery mode. I have wiped and reset from recovery with no help. I can access adb and fastboot on the pc but it won't let me write any files because of the locked bootloader. Anything I try to sideload so far gives an error. Any further suggestions?

Hi,
My Nexus 6p was running the latest OTP update of Android Nougat successfully, Suddenly while using google maps it, restarted and went into a boot loop. All i can see is the unlocked bootloader warning (i had unlocked the bootloader earlier) and then the google logo.
I am able to go into bootloader mode and my system identifies my device as a fastoboot device .
I was able to access my stock recovery but while trying to fix my phone, i tried installing twrp recovery and now whenever I choose the option of recovery mode using my volume keys. it again shows the google logo and nothing happens after that.
I have tried many things, but I am not able to resolve my boot loop. Somebody please help me. Please guide me what should be my approach to this problem

FOLLOW THESE INSTRUCTIONS ONLY IF ANYTHING BETTER DOESNT COME UP BECAUSE I DON'T WANT TO FEEL GUILTY IF YOU "FUBAR" YOUR PHONE. I am not an expert in this stuff.. I can only follow instructions and the two videos helped me get out of crappy situation in the past couple weeks.
Follow the two videos below on how to re-install your drivers properly and flash and root Nougat 7.0
First go delete your driver from your PC via Device Manager. Anything that you can associate with N6P or Google.
Then watch this video on how to install new drivers.

If you can access fastboot, I would just follow Heisenbergs guide (look In the stickies) and reflash the N stock images manually via fastboot. Also, make sure that you flash the recommended TWRP version that he has linked in his guide otherwise you will have problems with recovery. His guide has saved me multiple times when I messed up my phone.

I think I figured out mine problem. I am not sure what you mean by locked bootloader but in my case I was able to reboot to bootloader by pressing all three buttons (Volume up, Volume down and power button) at the same time.
Once you are there and if your bootloader is already unlocked you can flash your own android. Probably this process is called unbrick your phone. I am surprissed and sad as I am not allowed to post link which can help you. Ask admin.
Any related problem while following process. I can try as I am not very expert.

And that's why it's a good idea if you do ANY tinkering to your phone that you have an unlocked bootloader. I have screwed my phone up a hundred times over but nothing that a fastboot flash of the stock Google images couldn't overcome.
I'm not sure what situation you're in but I would try to get that bootloader unlocked asap. Just know that when you unlock it, every partition on the phone will be completely wiped to include internal storage (sd card).
I wasn't tinkering that's the thing. I was on the Android beta but I have installed those OTA. I would love to be able to unlock the bootloader but none of the commands will work to unlock it because usb debugging was not enabled or the developer options and I can't boot it to change that.
My Nexus 6P is seemingly bootlooping.
I can boot into the bootloader menu but not into recovery. My bootloader is not unlocked so I cannot flash anything.
Issuing the command: "fastboot flashing unlock" does not work nor does "fastboot oem unlock". I cannot flash a custom recovery. Because my bootloader is locked.
Any help would be great.

You say that your bootloader was not unlocked, so I'm assuming you didn't have developer options turned on and USB debugging checked before fastboot flashing unlock?

Do you remember if you modded anything prior to bootloop? The reason you can't unlock bootloader is because USB debugging isn't on. What version of Android were you on when it happened? I believe you can still use google factory Image to restore your phone.

Since you don't have twrp you probably don't have a backup, which what I'm going to suggest will bring you back to stock and may lose everything. Though it's better than a bricked phone. Since I never did the flash-all.bat you may lose your stuff on internal SD. In this link, download the correct image your phone was on (under angler) and if using windows use the flash-all.bat in fastboot. If you're phone isn't 32 GB, extract all from zip and flash everything except user data. Forgive me for assuming you may be new. https://developers.google.com/android/nexus/images

Tried that. Continue to get the "Remote: (device is locked)" error every time it tries to flash a new image.
I'm not worried about losing any data on the phone. everything is backed up in the cloud.

Do you get the error on all that you try to flash? Maybe just try the recovery img only to see if you can at least get that. If that works you should be able to sideload ota through recovery. With having a locked bootloader you might be at a loss. But on the flip side, having everything locked and not rooted you should be ok for warranty replacement.

Fastboot is useless since your bootloader is locked. Try to ADB sideload the latest OTA image from Google and see if it will boot.

How would i get into ADB mode without being able to boot into recovery? I thought of this as well but haven't been able to find a way to boot it into an ADB mode

Ahh, missed that in your first post. I'm not sure how you can get recovery going if it's bootlooping when you access it.

Check out this thread at post number 268 they mention using adb through mtp mode when not able to use recovery.

Tried running through those steps. I can't even get a temporary boot of TWRP or stock recovery continues to bootloop even though WugFresh claims it was successful. Tried doing it manually via Fastboot and continue to get the error in flashing.
I just received my replacement phone. So I might just call it a day on this one. :crying:

Good to hear about replacement! There are a few people in these forums that have a brick and can't get out of it. I thought you couldn't Hard brick these phones unless that was your goal. And most of these users who have bricks don't even know what causes it. Just a random reboot then loops. Kinda scary.
My 6p is stuck in a bootloop. nbd90x build my bootloader is locked is there anyway to unlock from adb. I have already tried sideloading ndb90x through adb wipping chache and user data and still no luck. Help me Xda youre my only hope..
So you previously enabled USB debugging, how about OEM unlocking? If so, use 'fastboot flashing unlock' to unlock the bootloader. Note that internal storage will be completely wiped. Everything. Though with USB debugging enabled, you should be able to adb pull the contents of you SD card first. If you can unlock the bootloader you can try flashing factory images with fastboot. Otherwise, not much else besides RMA it with Google. There's been a few reports of stock N6Ps bootlooping. Haven't seen anyone post that Google denied the claim.
no bootloader is locked so cant flash using flashboot but debugging is enabled so I am able to use adb .
I know. What I'm asking is if you enabled allow OEM unlocking in developer settings? That doesn't unlock your bootloader in itself. You still need to use fastboot to do it. However if that setting IS enabled what you can do is... Use ADB to pull your internal storage to PC. Then use fastboot to unlock the bootloader and flash factory images. If the setting is not enabled, and wiping data and flashing an OTA don't work, I'm not sure what else can be done.
You can try downloading the 7.1 dev preview OTA and seeing if it updates whatever is causing it to fail. Other than those, RMA would be your best bet.

After sideloading a ton of times between 7.0 and 7.1, one time i got it to boot up then i immediately enabled oem unlock then it crashed again... so now I am able to flash through fastboot although I havent been able to get it to boot again. Is it normal for bootloops to not get fixed by flashing?
Hijacking your post to report what is happening to me. I posted the same thing on the Android Beta program community on G+.
Have been using the latest beta since it came out on completely stock 6P (locked bootloader, unrooted). Everything working normally when yesterday around 10 or 11AM, phone starts to bootloop OUT OF NOWHERE, it was just sitting there on the table while I was working. I could still get to bootloader/recovery, so that was a bit of a relief. First thing I tried: clear cache, nothing. Then proceed to wipe/factory reset the device, to no avail. Immediately downloaded the latest factory image from Google's page, tried flashing it but couldn't since the bootloader was locked (OEM unlock option also disabled). Then downloaded the beta OTA and sideloaded it, process went through OK but device still bootloops. Tried sideloading the latest stable OTA but didn't work since it was from a previous build. Ran out of ideas. So there I was creating a thread on XDA for help while the device was still on its bootloop rush, about to hit the Submit button when again OUT OF THE BLUE SKY the device decides to boot itself back up. First thing I did was unlock the bootloader. Phone worked normally for 6 or 7 hours, when I'm doing something on it and then again, screen froze and bootloop starts again. This time I only reset the device and left the it bootlooping, after about 30 minutes it boots up again. I unenrolled from the beta and installed the latest 7.0 build. Everything working fine for the last 12 hours. Anyone have any idea on what can cause the device to bootloop like that? Never seen anything like it.
Yea I signed up for the beta program too do you have the link to unenroll? So you just reset and let it sit?
Here you go

do you remember what you did to get it to boot?

Well, that's the thing. Everything I tried didn't seem to work. I couldn't flash the factory image since the bootloader was locked. I was able to sideload the beta OTA but the device still bootlooped after that. So I just left it bootlooping and after around 20 or 30 minutes the device booted normally. I have no idea what caused it and what I did to make it work again.
P.S: device restarted 2 times while I was typing this.

If your boot loader is locked you are screwed, sorry to say, I would RMA it. Unbelievable an update can mess a phone up...that's why I always unlock the bootloader first thing and never lock it. I need complete control of my phone.
Edit: Only thing I can think of is delete the partitions with fastboot or adb and reflash factory image.
boot loader is unlocked now Ive tried flashing using the flash-all script but the phone still wont boot

As a last resort, flash all of the images manually with fastboot. This will wipe all userdata and completely format the SDcard. Nothing will be left. Extract the bootloader and radio images from the factory images zip. Flash them in fastboot. Reboot to fastboot again. Extract the next zip in the same folder as BL & radio images and flash the vendor, system, boot, recovery & userdata image files. Just for good measure, boot to recovery (stock Android recovery) and perform a factory reset & cache wipe. If the phone still fails to boot, your only option would be to RMA it at this point.
Note: As per Heisenberg's sticky thread, do NOT flash userdata.img if you have anything besides the 32gb model as you will only have the ~32gb storage available. If you're using a model with more storage, just use fastboot to format userdata but don't flash the image.
Ill try that.. but isnt the warranty voided because the bootloader is unlocked?

Not on a Nexus, no.
Added: I had to RMA mine after the phone got its first update. I unlocked the bootloader and stayed stock for a long time (until N came out). I took the OTA in About Phone and it applied with no problems but the phone would not boot. Factory images also couldn't get it running. Stock recovery and all. RMA'd without issues. I didn't tell them, just sent it in. If they tried to boot it they would've seen the unlock symbol. There's also a thread somewhere buried in the general section where someone called Google and asked and they confirmed to them that unlocking does not void warranty. I'll try to find it for you.
Found it: http://forum.xda-developers.com/nexus-6p/general/unlocking-bootloader-warranty-google-t3229804/page1
I also returned 4 faulty Nexus 5's (mostly screen artifacts) all unlocked with no problems.
I`ve decided to return to stock and I wish I didn`t!
After flashing the files for the latest stock image , I was unable to pass the boot animation.
That was six hours ago.
I tried to reinstall another full image from google website.
I did and then my computer doesn`t recognize my device on adb mode.
Tried to update the drivers via Android Studio and through the usb drivers folder , it gives an error of not being able to download the update because of disabling the automatic windows update even though I did.
Help, people what can I do?
Should I just get a new phone?
It`s a very tough option for me right now due to some financial issues.

Hi... Explain how exactly you flashed your phone. Fastboot? Adb sideload?
What was your android version prior to your problem.
What version did you try to flash? Did you use the flash all.bat/sh? Or flashed each image manually?
Are you stuck in bootloader? Can you still access recovery? Or does it bootloop when trying to reboot into recovery?

No, unlocking the bootloader may make the difference in being able to recover your phone. Did you also enable USB debugging in Developer Options when you unlocked your bootloader? Was ADB working before and now has stopped working? I would first focus on getting ADB/fastboot binaries (and USB drivers) set up and working properly on your PC.

No you just need fastboot working to unlock (this is assuming you already had it unlocked before)... but again this depends on you having your PC set up correctly.
fastboot flashing unlock - try that and see if it finishes successfully or not.

I unlocked it before but now did a full recovery to Stock and locked the bootloader.
I need to access the usb debugging option before I can type in that command in the CMD
My PC is set up correctly .
My only problem is that I don`t have access to my phone in order to enable that option and don`t know how to unlock the bootloader with any other way.
That is all

Fastboot
What was your android version prior to your problem.
7.1.1
What version did you try to flash? Did you use the flash all.bat/sh? Or flashed each image manually?
The same version again after flashing a pure nexus rom , flashed each image manually

not stuck on bootloader , still have access to the recovery mode (stock one not TWRP) it bootloops only when I try to turn on the phone.

What version are you on? 7.1.1?
Try sideloading the beta 7.1.2 ota. You can find it on the N6P general section I think.
I'm not saying it will solve your problem. If factory reset didn't fix your bootloop, I don't know what else to do... Good luck!
