Because they are trying to make it a consumer phone as well as a developers phone. The average user doesn't need these settings, and could very easily mess up their phone by using them. With such an easy method to re enable them, why not do it?

Sure good to know, but what does it have to do with the bootloader? I thought that to unlock bootloader, you only need to "fastboot oem unlock"?
It's unlikely that I need to change an option in the menu in order to unlock... What if I somehow screw up and can't boot, and then lock to bootloader? Stuck with a brick?

You need to get into developer settings and activate USB debugging so you can use adb to proceed to unlock the bootloader.
Also I find the way to unlock developer settings to be quite humorous! Sadly I can see many impatient users looking to access said settings the first time be be put off by this, hopefully they will see reason!
Awwwwsome

You don't need adb to unlock the bootloader! Unlocking is done in fastboot mode, so saying "This is essential to get an unlocked bootloader" is wrong.
You can get to the bootloader (fastboot mode) by pressing the buttons during boot.

This is not just directed at the OP:
I think people should wait until they get a hold of the device before posting guides and directing others on what to do. Unless you actually try something and it works, I wouldn't be posting any guides.
Just to clarify some mis-information in this thread:
1) You do not need to install the SDK (and you do not need it to install the driver) -- the SDK is just a bunch of stuff that, unless you are developing, you will never need;
2) The driver for the N4 may not even be included in the SDK -- the GNex driver certainly wasn't;
3) For the fastboot driver to install (and for fastboot commands to work), your device must be booted in fastboot mode;
4) USB Debugging is a feature of Android, and to use it, you have to be booted into Android -- it has nothing to do with the bootloader;
5) Currently, there is no exploit to gain root on any build of Android higher than 4.1.1, so, there is no way to gain root without unlocking the bootloader at this time.

Also, 2 responders above in the same page say that.
Also, it doesn't make sense to me that fastboot's operation will check an option that is selected while you are in the OS.
If someone that has the device can check it then great, until then I'll assume USB Debugging is NOT needed to unlock bootloader.
Hi!
Today I updated my Nexus 6 to 5.1 and something is went wrong...
When i try to boot my device into android, i Can't because its shows a dead android with a red triangle
(this is the screen where i can go into the recovery menu by pressing power on+ vol up)
i tried to flash the rom again, but the bootloader is locked because i relocked it after the 5.1 rom flash..
and i cant unlock it again because i cant boot into android to check the OEM unlock box.
i also tried wipe data, factory reset option in the recovery menu... thanks a lot for any suggestions
(sorry for my english)

Why in the world would you relock the bootloader? Against commonsense it would seem. Also, there are threads on here dealing with the update and warning against relocking the boot loader. Those threads also describe efforts to recover from the situation.

I haven't seen anyone warning against relocking the bootloader - in fact, I see many instruction sets where relocking the bootloader is the final step, before the first reboot. Most are for returning to stock. Go ahead and use your hindsight though, you sound so smart.
And yeah, there are plenty of efforts to recover from the situation, but I'm yet to see anyone do so successfully.

If you want to update to the newest OTA you dont need to lock the bootloader back up. The bootloader can remained unlocked when doing this. Its been posted all over XDA about not having to do this. The only time you may want to relock the bootloader is when selling it to someone or trading it in. Thats it.

returning to stock and relocking the bootloader dont go together. You can return to stock and not lock the bootloader. Locking the bootloader has nothing to do with returning a device back to stock. It returns the device back to factory state if u lock it back up. Locking the device back up only should be used for selling the device, or returning the device for repairs. not for taking a ota.

There is no downside to a unlocked bootloader. If i remember correctly a locked bootloader is only for oem to protect for warranty issues nothing to do with security that your describing. A locked bootloader or unlocked bootloader tells the oem that this device was unlocked or locked and will tell the consumer (us) that the warranty was void. Number one rule when taking a device back to OEM for repair is return to stock and lock device like I stated above. Security issues has nothing to do with the bootloader. From my understanding its just for the OEM warranty purposes Only!
Edit: what u described above is the same thing I described. Only need to lock device back up for warranty purposes or reselling. Thats it.

I posted the warning because people are not being careful. They are locking the bootloader without even checking it works. I've edited the post to say that. But if you're the sort of person that will be flashiogn a lot, a locked bootloader is not a good thing to have now because if you break recovery and cannot boot your device, you are at present - completely screwed. If you want to be stock, that shouldn't be an issue. Just be careful is all we're saying. ...and I cannot help it if my warning comes after some people have made this mistake. If no one made the mistake, I wouldn't have needed to post a warning. Can of peanuts "May contain nuts"... You know, because you know someone somewhere who was allergic to nuts, ate the nuts.

Locking the bootloader without even checking it works - again - I don't often see the "reboot to make sure it works!" step before the final fastboot oem lock. Maybe I've only been reading the lousy guides.

I thought that an unlocked bootloader allowed someone without 'normal' access to the files on your phone. That's why the bootloader lock/unlock wipes the device.
You're still completely missing my point with the warranty thing. Suppose my phone's unlocked and my screen breaks. Or my USB port stops working. That big unlocked logo under the Google is going to make getting a replacement really difficult.
By saying there's NO downside to unlocking the bootloader for daily use is absurd. I wanted to go back to as-shipped state for daily use, and locked bootloader is part of that. That's a reasonable goal. I don't care if there's something about the bootloader unlocked that you find valuable. I got tired of the tinkering and decided I just wanted my Nexus 6 to be back the way it was - completely.

Root access is for the special files. and also i had the same issues u mentioned above and i always found a way to return a device to stock.
1) broken screen- repaired myself
2) broken usb port - repaired myself
I only take in for warranties if it has to do with something that I cant fix myself. This is a risk that all users take in this hobby.

its not laughable. unless u buy an extended warranty the warranty is up after a year so you would have to figure the work yourself. If you are in the boat where u locked it back up and took the ota and bootlooping or whatever. your stuck till there is a solution. if u want to return to stock . Just return to stock but dont lock the bootloader back up, and flash. its that simple.
Edit: we are not arguing. Its just i have my way on repairs and you have yours. its a debate i guess
Edit: this issue has been brought up and is being researched. i was talking about the returning to stock for repairs dont try and put words in my mouth saying i know a fix.
Due to organizational requirements the bootloader needs to be locked. So, here go the questions:
After flashing factory image (5.1.0 (LMY47E), is it safe to re-lock bootloader?
And when, after the final reboot and before setup?
And, will the command, fastboot oem lock, wipe EVERYTHING off the phone, like fastboot oem unlock does?
And does the Developer options setting, "OEM unlocking", need to be turned on prior to the lock?
Thanks
No one has proven that locking the bootloaders does not cause a "brick". We have seen people lock after 5.1 and get a bootloop. This becomes a brick because they cannot unlock to fix it. We don't know if the update causes the loop or the lock does.
By the way, this was a completely stock Nexus 6 (5.0.1), no root, no apps other than Google. Before the factory image flash, the "OEM Unlocking" setting in Developer Options was persistent during power on/off. Now, with 5.1 the setting turns itself off during power on/off.
So, should I re-lock the bootloader and satisfy organizational requirements and risk a boot loop or proceed unlocked? Kinda feel like a "deer in the headlights" !

Well its your choice. I recommend not locking it. However, if you do lock it and end up bricked, at least we know its the locking that causes the loop and not the flash but.... Is it worth it?
If your organization is supplying the device ( or the money for the device) you have no business unlocking it. At my organization people are fired for such things.
If they are not compensating you somehow then I don't see how they can make requirements on your device.
Sent from my Nexus 6
And if it is the unlocking/locking that causes the boot loop (hard brick) then any flashing operation that requires unlocking the bootloader will require that the system remain unlocked forever. A penalty that will afflict a portion (large?) of the Nexus 6 community. Was this an issue before 5.0? Makes one wonder if this is by design or accidental.

Yes we totally can. If you work for my company and decide you would rather use your own device for corporate email and data, that data is ours. You may use your own device but we will manage it. If it gets stolen, we will wipe it. You will adhere the same policies for corporate owned data as you will with a phone supplied by us. You will have lock screen, you will be unrooted. You will keep your bootloaders locked. Or you can use this sh*tty Nokia.
My hardware, but if I want to utilize it in the organization, then I must abide by their rules.
This post was not meant to be an organizational ethics discussion, just a request for guidance. If anyone can give me input on the original questions, I would greatly appreciate it. Especially the wipe side effect of the lock operation. Do not want to spend a lot of time configuring the device if it will be erased.
Thanks in advance

Just a little thinking out loud here. Wouldn't it be safe to have OEM Unlock checked under dev options, lock the bootloader, if you happen to bootloop OEM Unlock is still checked so you could still unlock? And then upon first boot OEM Unlock would get unchecked.

Safe? No.. The flag resets at boot. Boot loop partially boots and it could be enough to reset the flag "at first boot"
Pretty much everything is an unknown here. We do t even know where the "enable OEM unlock" flag is set. Is it in the BL or one of the various partitions? What effect would setting the flag and wiping the OS have? We just don't know.

1. Unsure at this point. If everything is stock (including recovery), I would suspect that it would be OK, but it has not been verified yet.
2. After you flash the bootloader, radio, boot, system and recovery images, and format data and cache, then would be the time to re-lock and then boot into Android.
3. Yes. But based on what I gather, the process of wiping on an N6 (when unlocking or locking the bootloader) is done via the stock recovery. So, if you have a custom recovery when you lock, I suspect that it will give you a boot loop.
4. I don't know.
Update - Success
I re-locked the bootloader and the device is working normally, no boot loop. I will continue testing over the next few days and then share what I learned.
Thanks for the help ...
Upgraded to 5.1, booted system OK
rechecked the OEM unlock option and rebooted to fastboot and locked bootloader.
No bootloop or other issues noticed.
Hope this helps.

Interesting. And you were 100% stock?
Perhaps the loop isn't caused by the lock itself then. Good to know, though still people need to be cautious

This happened to me literally tonight. I tried to lock the boot loader which was successful, from there the device would start to root into teamwin recovery. So from there I tired to flash a fully stock rom but the bootloader was locked. And then because you need permission from the OS to unlock the bootloader I was stuck. What I did is from the locked bootloader I ran the stock oem flash from a fresh download and check from wugs with the force flash enabled (make sure everything is right) miracles of miracles it worked and came back to me.
I learned my lesson. Never shall my bootloader be relocked unless my phone is out of my possession. I'm spending the rest of the time making sure that nobody can get to my data. I love the phone, but that data is my life.
So basically, we need to confirm that being 100% stock will safely allow the relocking of the bootloader on 5.1 per official instructions from Google. If it can be determined that having TWRP recovery installed is the cause of bricks then users can be instructed to be sure stock recovery is installed before relocking. My own thoughts are that this is a bug of sorts with the new security features of lollipop and I'm sure the talented folks here will get it figured out. I'm 100% stock on LMY47D that I sideloaded. Not sure I can afford to risk my 6 but I offer any assistance I can to help get this figured out.

Some of the "bricks" happened after fully flashing stock, i.e they had stock recovery. They had a locked bootloader, an OS that didn't boot and a recovery that couldn't flash anything. If they had TWRP installed, they could format data and flash a rom.zip no problem.

If that dosent work you can also follow the below procedure.
Relock your bootloader. Your phone will factory reset and boot. Then head to developer options and you will see oem unlock is not greyed out. Then just enable oem unlocking and unlock the bootloader. When you boot up again you will see that oem is greyed out but it'll be enabled. So you'll have unlocked fastboot and unlocked frp now.

Everything fine. I believe it's completely safe if you have complete stock firmware installed ie, stock rom, stock recovery, stock Kernal and all that stuff. Otherwise you'll end up in a loop. Guess I forgot that part sorry.
So I know this is someone else's thread but can you tell me if I relocked bootloader will the service center be able to know I'd unlocked before? I don't have the phone unlocked warning at boot. Just curious.

Some if not all bootloaders nowadays are not "locked" by the manufacturer using a code but are usually "locked" by employing a digital signature and/or a CID (carrier Id) hard coded into the OS. When we "unlock" a bootloader with a code we are simply using a routine written into the loader by the manufacturer to now ignore signatures and/or CIDs of the OS and this allows us to flash whatever we wish.
Sometimes upon unlocking using a code the DS/CID is erased/altered and cannot be retrieved, so not a good idea to relock an altered bootloader.
At least, that is my understanding of it.

That's too bad. Means we won't get back our waranty if we relock it ?. So thanks for the heads up . I'll be careful while unlocking it again (if ever).?

Not necessarily, I doubt if most service centres would bother delving that deep, but maybe some would.
I don't know...........

Thanks for your quick reply but do you know any way to get back CID/DS
No, but I haven't delved that deeply into Huaweis bootloaders, but I NEVER attempt to re-lock them.

Hello
Hoping somebody can help getting my phone up and running again.
I wanted to unroot my phone, because i was having issues with danish "MitId". And was a bit sloppy with it.
First i tried using SuperSU to remove root. Because i didnt feel like setting everything up again. Didnt work.
Then I locked the OEM Lock in developer settings. Not thinking this would be a fatal error.
Got home from work, and said to myself. Jusk lock the bootloader and the phone will reset itself.
But this is not the case, when you have been stupid enough to lock the OEM lock.
Now I am stuck on "No valid operating system could be found. The device will not boot"
I can get in to fastboot by pushning power+vol down. But cannot flash anything since the phone thinks the OEM Lock is locked on it.
Does anyone know of a solution for me. Or is it going to the shop tommorow and say that my phone is going this. And hope they will sort it for me?
Can't you fix stuff by using https://flash.android.com/ ?
No, unfortuantly not. It fails:
Device Unlock DisabledFor security reasons, you need to enable "OEM unlocking" in order to flash your device. See the device preparation instructions for more information.

Try sideloading the full OTA. You don't need an unlocked bootloader for that.
Unfortuatly not, if I try to enter recovery mode. The phone just goes back to the screen saying "No valid operating system could be found. The device will not boot"
ADB is not available to me
If you can't sideload the OTA, I'm afraid there is not much else you can do with a locked bootloader except try to RMA it.
Can you get into recovery at all. Even if it's the stock you can attempt a sideload of the stock OTA.zip from Google. You may also try if your on boot slot A
fastboot --set-active=b
On b use
fastboot --set-active=a
Try to see if the other boot slot has an a bootable OS.
*****I apologize I just saw it's actually still locked****"
Contact U-break I-fix if I typed that correctly. The third party warranty repair center for Google's warranty. I believe they can attempt to switch the boot slot with a locked bootloader with the equipment they use to reflash these devices. If anything it's under warranty get the RMA and if the bootloader is locked on it trade someone or sell it and use it to make buying a new cheaper..

No, I can get into fastboot and that is it.
But everything I try in fastboot gets rejected, since it says the phone is locked.
Does the bootloader screen on the phone have the option to boot into Rescue. This has a ADB connection but I am not sure if adb sideload works
Really mad that Google intentionally locks phones this way, turning them into completely functional, but useless piece of junk. I guess that's late stage capitalism for you xD

Google is not responsible for phone's with locked bootloaders. They make the device with the specifications the carrier that sells it stipulates. Google themselves allows the unlock.

Iam guessing the same. Phone doesnt want to do anything.
And since i cant get into the phone to oem lock i am stuck. Live in Denmark, so by law I havnt voided the warrenty by rooting.
Pixel warranty is always valid even if you unlock and root. Google doesn't void the warranty. Go to Google pixel support page. Find warranty and act as if your submitting a RMA and it will tell you after you enter the device IMEI how long your warranty is valid for
Delete
If that were true. Android flash tool https://flash.android.com/welcome
Would work as it's the same process for the browser to flash the very same file. Motorola allowed signed factory img on locked. Google had never allowed that in fastboot as far as I am aware
DroidRommer said:
All you need to do is go here Factory pixel firmwares and scroll down to pixel 7 panther assuming you're not on the pro (cheetah)
-select the latest version for your model whether that's Verizon or whatever if you have the carrier unlocked one like myself just choose the Feb firmware that doesn't have a carrier name at the end of the firmware number (you should have your phone plugged into your PC and in fastboot mode) click flash and follow the steps. These are Googles factory images so it doesn't matter if your bootloader is unlocked or not as long as you choose the latest version and the correct version for your phone. Tbh you can't really brick the pixel 7 as long as you have a PC and are able to put the phone in fastboot mode (holding the volume down and power button while powering on)
-Anytime you run into some kind of bootloop issue or wanna get rid of root flashing the stock firmware from this website will factory reset and revert your phone to the way it was the very first time it was pulled out of the box and powered on. If you have already tried this and you know forsure you did everything correctly then I must admit I have never had this happen and I'm someone who flashes custom roms and goes back to stock to get the latest security update just to turn around and flash another custom rom right after lol. If you need any help or advice feel free to pm me whenever. I have been rooting phones for a long time and have to say that the Google pixel is by far the most user friendly phone I've ever owned when it comes to custom rooms, rooting etc. You can ALWAYS go back as long as you know what steps to take. Sorry for the rant especially if you already figured it out.
Happy Customizing!

Their bootloader is locked. You cannot flash a factory image like that with a locked bootloader. They also turned off OEM Unlocking in the developer settings. If they had left this enabled they would be able to use Android Flash Tool as that tool will unlock your bootloader if OEM Unlocking is enabled.

This wouldn't be Google, they basically encourage you too unlock the bootloader and root if you want as they give you all the tools you need and factory firmware options to go back if you make a mistake. Tbh if you are able to unlock and root the phone to start then you can go back. Even with a locked bootloader you can always flash the latest factory image on googles dev website, you just can't downgrade firmware or install different carrier firmware without the unlocked bootloader. If we really wanna poke at some phone developers I vote Samsung as I have had multiple people ask me to root their phones and if it's a US snapdragon version it cannot be done its so frustrating lol thanks for letting me vent, have a great day if you have the the carrier unlocked dev edition of the pixel 7 and ever need any help feel free to pm me. I have been rooting and romming pixels for a long time
Edit: I was not aware you couldn't flash the stock firmare using googles dev page without oem unlock. I apologize for jumping to conclusions. I thought I had every possible bad scenario happen to me by now but apparently I learned something new today.

Dude. You cannot flash factory images of any kind on any Google phone with the bootloader in locked status. Please stop giving false information on here. If you want to talk up Samsung do it on a Samsung post. Let's not confuse everyone please

To use Android Flash Tool, you have to have OEM Unlocking enabled in Developer Options for it to be able to unlock the bootloader.
To flash the factory image in fastboot you must have an unlocked bootloader.

Okay my bad you are right fortunately I have never had this happen. And like someone else said if he can't get into recovery then he can't sideload a factory ota... sorry I'm at a loss on this one. Some custom roms use "fastboot update file.zip" would that do anything in this case or would that command not even work with a locked bootloader I'm assuming. I apologize for trying to act like a know it all I've just never heard of this happening
