i know there are a ton of discussions on this but it seems that every thread just dies off and nothing in depth gets discussed. oneplus is useless in this, and it also figures that the phone would wait for me to pay it off before it self bricks for no reason.
i know im gonna have to wipe it at some point, but i REALLY need to get some data off of it. the bootloader claims its locked when i know i unlocked it forever ago, and nothing that fastboot offers is doing anything for me. i cant use oem unlock, i cant flash anything to it, and unlike earlier today, multiple reboots no longer bring it back to life.
so, is there a way i can force this paperweight to take a dirty software load? or can i get fastboot to dump all my data into a folder or something? i havent been around really since the CM days, and Im very sure I simply cannot search for the right terms in the right places.
ive also made posts in the xda and oneplus discords with little reply (it is late in the US so im not overly surprised about that at all.
as an update, it booted into recovery this morning, i backed everything, unlocked the bootloader, and got about 5 hours out of it.
after getting fastboot to finish the oem unlock, i tried flashing twrp recovery which did nothing, flashed carbon, which did nothing, used the MSMdownload tool, which has done nothing but relock the bootloader again. im at a huge loss here.
is this motherboard level?
Alright mate. Sounds like you're having a mare.
Personally I haven't had a single bootloop besides, OnePlus do provide tools that a lot of companies don't, like MSM, so be grateful for that. Plus it's super easy to unlock and relock the bootloader, also OnePlus will allow you to retain warranty even if it has been unlocked.
So go easy on OnePlus. Believe me it could be worse, naming no names.........
Samsung. LG, Motorola, Sony, apple.
As for your issue, when and how did it bootloop, it is quite rare for a phone to simply behave that way on its own
Are you / were you rooted?
Did you confirm that the bootloader was unlocked? If you're rooted then I think that confirms that you did.
The only way I know of to relock the bootloader is the fastboot command to relock and or the MSM tool.
So can you fill in the gaps as to how you managed to get there??
Finally, if you are indeed bootloader locked and unable to get into your device then yep you're screwed, however you could wipe system from recovery, this will nuke your apps, but your storage will remain intact .
So if that suits your needs then go for it.
Let me know about the bootloader before you commit

I have seen quite of few people screw up their devices by not knowing what they are doing. So I am making this thread to simply tell people not familiar with fastboot what they should and should not do.
1. Fastboot oem unlock will unlock your bootloader and do a complete wipe of your device. As far as I know the only way for something to go wrong here is if you're device is low on battery and shuts off during the process. Either plug it in or have a "good" amount of juice left in your battery. To be 100 percent sure plug it in.
Before I get into oem lock IMHO you should only use this command for one thing only. Getting the device ready to send into motorola for the LGT upgrade or a another warranty repair or some sort. When done properly it is completely safe but there is no reason to do to go back to "stock".
2. Fastboot oem lock. Do not issue this command unless you are absolutely sure you have the correct software on your device. The correct software is what you get from the motodev site for your device. You need the official sofware images for your specific device AND REGION. If it is not released then DO NOT re-lock the device. If you have a OTA installed you will need to flash back to the motodev images first.
All this info is all ready on the forums in various threads already but I wanted to put in one place since I noticed quite a few users botch up the devices trying to update to 3.1 The last thing we need are a bunch of people bricking the devices and sending them in moto. I suspect if enough people do it they will end up changing their minds on the entire encrypted bootloader situation.
I know you have to unlock to flash "non-stock" images, but do you have to unlock if you are only going to flash the "stock" motodev images?
If I am currently just unlocked, not rooted do I need to lock in order to get the 3.1 update?

NO. the update only checks for stock files, not lock or unlock.

Question for you, how do I go about entering this command? My knowledge is basic. I have unrooted, restocked a Nexus 7. Trying to do oem lock without being able to use the screen. Cannot enable USB debugging because the screen is nonoperational. Any advice?
I'm new to Android. Recently I got a new nexus 6p. I was so confused that whether I have to unlock bootloader or not. Currently I just want to experience the pure Android simply without rooting or changing anything. But I heard a lot about bricked nexus 6 that the device would not be manually fixed if it was not bootloader unlocked before. As I am in China where I have no warranty for my nexus 6p, I have to keep my device safe as possible as I can.
So my question is under the circumstance that I haven't unlocked bootloader or OEM:
How much probability could it be I do nothing but unexpectedly brick the device?
If it is bricked, is it possible to recover it?
Do common nexus 6p users have to unlock bootloader?
Another important thing should be mentioned. Generally I can't access to any service by google in China, so I utilize a proxy tool to get over the great firewall to use google. Is there any experience about the situation like me? I also heard a saying that upgrading nexus 6 firmware by OTA through a proxy tool in China may brick the device, because google can not save the upgrading information of the device for the reason that the proxy IP is not static, then google will push update again, and once you click it, brick.
Puzzled enough...Thanks in advance.
I am not 100% certain what you are asking... If you do not unlock the bootloader, you should not be able to brick your device. The only reason to unlock it is to flash a custom ROM (not official from Google) or to flash Google factory images, which it sounds like might be necessary for you being that you are in China and may not receive OTAs properly. This is a process of downloading a file from Google and flashing to your device after unlocking the bootloader.
Your post was not exactly clear partially, but is your phone already bricked and you are trying to recover, or simply asking for your own reference?

Thanks for replying. Could you please point out the unclear expressions? And I could edit them.
I have only unlocked nexus 6p bootloader, and the device is running well. I do not understand exactly why I have to do this, I just do it in case the situation described by other nexus 6 users happen to my nexus 6p. So I want to figure out the logic.
If you have no reason to unlock it, then you can relock it. Unlocking will always cause a full wipe (factory reset) of the device. Some users have stated that relocking the bootloader will also induce a wipe. If you want to leave it unlocked, this will allow you to flash factory images (such as updates from Google) as often as you'd like. It is possible to flash a factory image without losing any data by modifying the batch file used to flash the firmware.
Simply having the bootloader unlocked should not pose any threat to your device. You have to try very intentionally to flash firmware and risk bricking the device, it's not really something you can do by accident. The one thing I will mention is that with the bootloader unlocked, someone with the correct knowledge could flash a new image on your phone without needing your password or other security information. They would only need to power off the device, enter bootloader mode and plug into a PC to begin flashing. This would remove every trace of you and your data from the device and make it like it was brand new from the factory.
By keeping the bootloader locked and the "Allow OEM unlocking" option turned OFF, a person would need to have your password (or fingerprint) to gain access to this option in the settings, thus not allowing them to flash over the device as it is today.
Hope this helps.

According to you, I should not be able to brick my device if I did not unlock the device. I can understand this. But the problem is I am in China...By using proxy, I could receive OTAs correctly. But some nexus 6 users in China still encountered with device bricked after upgrading firmware by OTAs even they didn't unlock bootloader. One possible reason is like what I mentioned in last paragraph #1.
I don't like the prompt each time when I reboot the device after unlocking bootloader. Let's make the problem simpler. Can I unbrick the device if it is bricked and bootloader locked?
I can't really speak to your concern regarding bricking from OTA. This should nearly never happen, but I would suspect that the proxy is the issue. If you are concerned about that particular instance being an issue, I would simply not accept the OTA and don't install it. The file will download to your device and you will see a notification very similar to this: http://images.tapatalk-cdn.com/15/08/12/1c244e92c6a0cd69ca6e1a3037a05d62.jpg If you do not click Install, it will not install itself. You can click Later but usually cannot dismiss the notification. I have had the update pending on my Nexus 7 tablet that I don't often for months, but simply have not upgraded because I don't use it often enough to justify it.
If you want to be on the latest firmware for security reasons (Android 6/M will have monthly security patch releases from Google), you can download the factory images and flash yourself. However, if you believe there may be an issue because of the proxy you are using, the factory image could face the same issue as the OTA as you described. As I said, because I am not in China and do not use a proxy as you do, I cannot comment on how or why other users may have faced a hard brick scenario.
Ultimately, having the bootloader unlocked will allow you to flash the factory image over a bricked firmware caused by a corrupt (or otherwise unusable) OTA. If the phone can enter bootloader mode, you can flash the firmware and restore it to like new state. The warning message you see when booting is not able to be disabled without locking the bootloader again, but it only appears for a few moments. It was previously hidden on the Nexus 6 (not the 6p) so it might be possible in the future, but that is just a guess.

The decision to leave it unlocked is the right decision. The other person replying in this thread is completely wrong when he says you can't brick a phone if you don't unlock it, that's completely and utterly incorrect. Sometimes things happen, unforeseen spontaneous problems happen all the time with smartphones. If this happens to you and your bootloader is locked there's absolutely nothing you can do to fix it. So yes, leave your bootloader unlocked as an insurance policy against the unforeseen.
@fury683, I'd think twice before telling someone that nothing bad can happen to their phone as long as it's locked, this is false information, and could potentially lead to someone being unable to repair a soft-bricked device due to following your advice.

The choice is ultimately yours, but my advice is always to have it unlocked, that way you're able to access and use fastboot in the event that something goes wrong.

Yep what Heisenberg said is 100% true. My phone got bricked after the OTA update resulted in an error. I hadn't enabled the OEM Unlock setting, so couldn't unlock the phone. Have to wait for a replacement now
Hi There,
My colleague complained that he had an OTA update on his Nexus 6P and the after the update it was stuck in a boot loop where the Google logo keep on displaying.
When he bought back, he had showed it a shop already which they said they couldn't fix. However, the phone was later given to me for help and I have somehow manage to connect the device on fastboot and adb. Tried all the possible options such as unlocking the bootloader, loading .img's one by one... sideloading... etc.
No matter what I do, it keeps on doing the same boot loop. And when I leave the bootloader unlocked, it gives an error at first, then again goes back to the same.
Not sure whether what I am doing wrong or whether am I choosing the wrong build or so... would anyone care to advise?

So the bootloader is unlocked? Exactly which build have you attempted to flash with fastboot? Have you tried flashing one of the full OTA zips with the stock recovery?
PS. Whatever you do don't lock the bootloader. And don't worry about the warning you get with the bootloader unlocked, that's normal.

Thank you for the reply.. I have only locked the bootloader when I'm done with flashing... etc as it was giving me error. Regardless of the bootloader state, it kept on going through the bootloop like it didn't care.
I tried to flashing the factory image which is MTC19T and also tried the OTA which is MTC19V as said in here.
Still there's not luck!

Don't worry about the warning and definitely don't lock the bootloader because if it gets stuck locked you'll really be screwed. Go to my guide here:
http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928
Follow the instructions in section 10 (use the latest MTC19X build). Skip the part at the beginning about performing a factory reset because you can't actually get the phone to boot to do that. Make sure you include the "fastboot format userdata" command at the end (this will erase all data on the device). Leave the bootloader unlocked.

It probably won't work, any build should work, but it's worth a try. If that fails I can only suggest flashing TWRP recovery and trying to flash a custom ROM to see if that works.
So long as you have the bootloader.img and radio.img files, you can try to format boot as well, however Heisenberg may yell at me for even typing that
I had a similar issue - bootloop, but it was getting to the boot animation for about 3 seconds, then rebooting. When I formatted all the areas before flashing them from the stock image, it allowed me to boot up as normal. Stable ever since.
Hi There,
Coming back to the issue, I have just downloaded the build that was suggested by "Heisenberg" and tried it. It was still the same, as in the Google logo keep on flashing but the android bot just appeared once with the logo. But still there not luck as the device stays with Google logo but does nothing.
However, I'm able to see the device on fastboot. Nevertheless, I cannot seem to use adb command.. it doesn't even list on devices. Does that mean the adb isn't working?
Meanwhile, all my fastboot commands are working with no issues at all.
EDIT: When I tried the TWRP recovery, I can flash the recover, but I can seem to go to the recovery window at all as the device keep on showing "The device software can't be checked for corruption". When I pass that also the same boot loop.
I too am having the bootloop issue on my stock Nexus 6P. Is there a way to unlock the device from the bootloader? I'm unable to carry out step one on Heisenberg's guide because I'm unable to actually boot up my phone past the Google logo. Am I pretty much screwed?

Unfortunately yes. Unless you enabled OEM Unlocking in the developers menu before your phone went sideways you probably have a hard bricked phone. Is it under warranty?
I went through this in November with a completely stock Nexus 6P. I was 3 days past my one year warranty! Google would not send me a new phone. It was completely bricked by the OTA update I received! I was put in touch with Huawei. I had to send the bricked phone to them. 10 days later I received a working model back. Unacceptable that an OTA update trashes a one year old $650 phone. Luckily I had my OnePlus One still, and was able to use that while I waited. I was even able to update that to 7.1.1 since it was rooted. Obviously there is some sort of issue that we are not being told of regarding the dangers of accepting OTA updates on a stock/bootlocked phone.

Bootloop issues are common on the 6P even with custom ROMs--it just happens to be much more likely you can recover with the custom ROMs installed since the bootloader is unlocked. I think it's a hardware issue with the 6P rather than an OTA issue. It's probably not an accident that Huawei didn't make the Pixels.
Doesn't seem right that I have to "void" my warranty and install a custom ROM on an unlocked, rooted phone in order to recover from a hardware defect. That's BS pure and simple. I want to use the latest software, that's why I bought a Nexus. I want to use all the conveniences like Android Pay. That's why I don't unlock or root anymore. I rooted every Android phone I ever had until now, starting with the original Motorola Droid. Now that security is so important to Google, and you can't use all the Android features with an unlocked bootloader, they need to step up to fix these problems.
This happened to my wife's phone, sent back to Bell. Will see what happens.

Unlocking the bootloader doesn't void the warranty on the Nexus 6P. If you are under warranty then just RMA the phone if an OTA bootloops your phone. It's your choice whether to keep the bootloader locked or not but if you keep the bootloader locked it's probably impossible to recover from a bootloop. Google keeps factory images for Nexus and Pixel phones on its website but you can't flash those images with a locked bootloader. Why would they provide the images if using them voided your warranty?
You are missing my point. If I unlock my bootloader so I can recover from a boot loop that may happen, I will no longer be able to use a huge feature of the phone. Android Pay will no longer function. In days passed the rumour was your warranty was void if you unlock. I assume that was started to keep people from doing it. All I know is I paid good money for a phone that is a disaster waiting to happen it seems.
If having an unlocked bootloader is so important to recover from a bricked phone, why do they lock it in the first place? And why won't Android Pay work with it unlocked? The answer is that you no longer have a secure phone if you unlock the bootloader.

Android Pay will no longer function. In days passed the rumour was your warranty was void if you unlock. I assume that was started to keep people from doing it. All I know is I paid good money for a phone that is a disaster waiting to happen it seems.
If having an unlocked bootloader is so important to recover from a bricked phone, why do they lock it in the first place? And why won't Android Pay work with it unlocked? The answer is that you no longer have a secure phone if you unlock the bootloader.

I think you bought the wrong phone. Nexus devices were never available commercially through carriers and were made for developers and people who like to flash things with their phones. There are ways to use Android Pay with an unlocked bootloader if you are so inclined. You are right that an unlocked bootloader is considered less secure but if you only install apps from Google Play or another trusted source you shouldn't have problems. You can also simply enable allow Oem Unlock in the developer menu. This doesn't actually unlock your bootloader but makes it possible for you to unlock it via fastboot if you get bootlooped and need to flash a factory image to restore. This way you can unlock the bootloader in an emergency but your phone is still secure. I think this should be enabled by default when the phones are shipped. Too many people with locked bootloaders end up with hard bricked phones where the Nexus 6P is concerned. Honestly, you would probably be better off selling your Nexus and getting something else that's more stable and made for people who have no Interest in flashing anything.
Hey all.
So I've installed LineageOS just fine - the unlocking guides around here are mostly clear enough. Certainly not as easy as I've been used to for Nexus and OnePlus devices though! I've been using the 'official' TWRP 3.0.4.1 and not any of the other (now often links removed) unofficial versions.
I've also got my hands dirty with EDL mode and have totally reflashed a couple of times while playing around.
So on to my question. Basically I have an email client for work (Good for Enterprise) that detects unlocked bootloaders as 'root' (even though I'm not rooted), so I would like to relock my bootloader.
However, as soon as I use 'fastboot oem lock' it instantly bricks my phone. It goes straight into EDL mode, from which it cannot return. No bootloader, no recovery mode, no booting of system. Completely dead. All button combos attempted etc.. The only way back that I've found is to flash a whole new system image in EDL, and start over.
So, have I missed something (a signed recovery?) that makes this happen? Are there some verifications that the bootloader does while locked that fails because there's a custom system and recovery in place?
Is there anything I can do about this? Am I doomed to use stock for as long as I need to use this darned app?
Thanks very much!
Yes you need to be completely stock to lock BL.
Also if you want to stay unlocked, you can use MAGISK to hide root for your mailing app.
Thanks for the replies. I actually don't have, and never have had, root. So the only thing it can possibly be detecting is either the custom ROM itself (or rather, not a factory one from some list they maintain) or the unlocked bootloader. So I doubt MAGISK will work, because there's no root there to hide in the first place
(In case it wasn't obvious, we're talking about Good for Enterprise here).
The blackberry mobile device management system (earlier called GFE) doesnt care if bootloader is unlocked, it just checks whether you have a custom recovery (twrp) and that is enough to flag your system as rooted.
Hey guys, I found this quick and tidy way to get a fastboot console inside the bootloader. You can use it to do stuff like "fastboot format (partition)", etc.
GUIDE:
Go to fastboot mode on your Pixel XL
Open a CMD on the computer in fastboot directory and write in "fastboot flash bootloader pixelcustombootloader.img" (make sure the bootloader is in the directory or else it will not flash!)

Note: I am NOT responsible if this screws up anything.
Also I do NOT know if theres and copyright trouble with this, if there is, Mods go take this down.
I wonder if this is the bootloader that was seen in screenshots that was used to downgrade a Verizon pixel to unlock it?

If the bootloader is locked you can't flash anything or boot anything that isn't signed by Verizon/Google/whoever.
As far as I know there's never been a downgrade workaround available where pixel8 wasn't patched, but could be wrong.

There was a guy positing pictures of someone from a cell phone shop where he was recording the procedure that they did to his phone it was a signed bootloader that allowed him to downgrade for an unlock. It was labeled HTC which people thought was weird.

Eh.. 3rd party pictures that don't come with a detailed "how to" are 99% BS or marketing.
Like I said I'm not all knowing but I'm pretty in touch with the goings-ons of the pixel and have never heard of a downgrade method for a locked bootloader.
If this shop has a private method of doing so then they sure as hell wouldn't let someone take pictures of the process.
Yea like u said the guy said they were spy shots that he snuck in. Probably bs like you said. I could careless for myself my Verizon pixel is unlocked. Feel bad for those stuck locked though. Wishful thinking I suppose.
Yeah, don't flash your bootloader with anything other than stock google imgs. If your bootloader is messed up, how do you get into fastboot to fix it? Can't change slots either afaik.
Thanks for sharing, this has loads of potential - could be used on-the-go to temporarily recover from the freeze/reboot glitch (flashing stock images tends to lower the probability of the glitch for a day or two), plus we could actually have tetherless TWRP support for Oreo with this as you could use it to fastboot boot the TWRP boot img.
That being said, I'm reluctant to flash a random bootloader on my phone with no info on where it came from. Did you make this? If so is it a patched version of the most recent bootloader? If not, where'd you find it? We need more info.
