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.

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.

Good point. That's why more heads are better than one. I still think my theory would work, but yet I wouldn't be willing to risk my N6 on it, wouldn't suggest others do either.

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

A few question, for understanding:
Rooted?
Stock or TWRP recovery?
Encrypted?

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.
Hey XDA,
I was rooted, unlocked and TWRP'd on I think 6.4? I realized I wanted to go back to locked and stock after seeing some of the security stuff come out. I used SPFT to flash the 6.1 Prime Rom, and everything was working great. Phone booted no problem, and seemed to work fine. I then tried to use the Wireless Update to update the phone. It looked liked it downloaded fine, but now I'm in a reboot loop, and recovery does absolutely nothing but reboot loop as well. I CAN get the phone into Fastboot mode, but fastboot flash recovery gives me a "failed to get permission" error.
I ran a getvar all, and here is what I have:
unlocked: yes
secure: yes
kernel 1k
bootloader: version-preloader 0.0.00
Version: 0.5
I've tried the SPFT tools again, but it gives me ERROR: S_BROM_DOWNLOAD_DA_FAIL.
ANY clue what I can try next to just get the dang thing to be bootable? I don't care root or recovery or what, I just want a working phone, and I'm running out of ideas.
Thanks!

don't panic. everything is as is should be in your situation.
you see when you did getvar all , it said
secure: yes.
that means it only wants to boot signed and secured partitions. Just get into fastboot and do "oem unlock".
you really cant (safely) relock the bootloader. If your boot loader was relock now, you wold be in a perminent boot loop condition not able to recover.
But you can save it with "oem unlock" from where you at now.
You rock. I thought since it said unlocked I didn't need to do it again, but that did the trick. Now I just need to figure out what to do with the phone. I wouldn't mind keeping root, but I want the B12 update.

The dirtycow thing was only needed to get to the unlocked point. He is already there, so his only issue should be the lack of sp flash tool. Until/ if he does the bootloader rollback.
Shouldn't be problem with the modded v7 to roll back either.
Because in order to install the modded version , you need to be unlocked and twrp anyway, right.?

I presume he flashed factory original 6.1 from Colton's site.
I thought flashing original rom with SPFT should result in safely relocked bootloader, why not?
What if he relocked bootloader with 'fastboot oem relock' command after flashing 6.1 but before taking 7.4.2 OTA update? This would also leave him with:
unlocked: yes
secure: yes?
There must be some way to bring phone to original factory state with bootloader locked (meaning unlocked: no secure: yes).
BLU support also cannot do this?

There is and I did it few times while testing my unlock script. Bit the chances of making a brick were so very high I cannot recommend doing it.
There are two other partitions that store the unlock state and they need to restored to really relock bootloader.
OEM relock does not work properly

Can you tell what steps you did to relock?
I really want to bring device to original factory state because encryption does not work when bootloader is unlocked. I did first dirty cow method on original 6.6 ROM (one with newer preloader), then rolled back booloader, installed 6.1 from ColtonDRG site with SPFT and finally installed vampireinfo's 7.4.2 thru TWRP.
However when I encrypted phone, in settings it says encrypted but I can browse device on PC without entering PIN.
On factory state encrypted device (with locked bootloader) I was not able to this

This will brick your phone, if you are not careful, and also if you are carefull. You can browse for help in encryption with unlocked bootloader before doing this, I'm sure there is a solution.
If you replace Seccfg.bin and Secro.bin from a backup from before unlocking bootloader you should be set to locked but I do not know of your phone will boot. You will be doing g that at your own risk.
But if you download the repair solution under the hidden tag(click to show content) in the roll back thread.
In that file it will restore you to 6.1 and it will be locked bootloader. I do not know about keeping v7 and relocked
I know that there are a lot of the missing OEM Unlock posts, but this isn't about how to force it to appear.
What I would like to know is that if I want to stay on the stock ROM, but I don't have the OEM unlocked option, would I be able to factory reset to clear out encryption and then root with Magisk?
The guide says that I need to have OEM unlocked to be able to root, so I'm curious what would happen if I tried to root with the OEM still being locked? Would I soft brick it?
This is quite different from the other phones I've used and it's extremely frustrating that Samsung decided to pull this kind of bs on everyone and so far, there's no solution to it.
Thanks
If the OEM switch is not visible and switched on, then you cannot flash any non-official binaries, which means you can't flash TWRP or Magisk, which at this point means you can't get root. That's why everything boils down to the OEM switch being enabled. Please contact Samsung expressing your dissatisfaction about this OEM issue. All of us should, until they react to remedy this.
If we can get to fastboot, why can't we boot TWRP, install Supersu/magisk and dm-verity thus gaining root.
This wouldn't replace the stock recovery.
I believe this was how the Axon 7 was rooted prior to bootloader unlock being presented/found.
I do this on one of my phones (not Samsung) as I only want root access and still be able to get OTA updates.
Would booting TWRP instead of flashing it trip Knox and would root be gained or would you find the boot partition or other system files be altered and you get the error that seems to popping up on these devices?
Just throwing this out there as food for thought.

Having an unlocked bootloader is what would allow us to use fastboot to boot or flash an image. Just because we can access fastboot, doesn't mean we can get it to write to partitions, even temporarily. I haven't messed with a Samsung phone for years, so I could be wrong. This has been my experience with google bootloader in general.

I was reading about this as well and what I got from that was in regards to custom roms, the oem unlock option is default to unlock and hidden. but for the stock rom, it's locked by default unless visibly given the option. otherwise when you go into download mode, it'll show FRP Lock: On.

Ah, but if I want to just root and nothing else, would I still need to have the bootloader unlocked? I'm used to rooting stuff but the technicalities and mechanics of the process escapes mr.
my hope is to atleast root the stock rom and factory reset including wiping the internal sd to start fresh. but if I factory reset on a stock rom, the internal storage would still be encrypted right?

This is why I want to know if we can boot TWRP. It boots TWRP but leaves the stock recovery.
However, I'm not sure if the boot image is altered when flashing root. I know Magisk seems to alter the boot image but not sure if SuperSU does.
Would this trigger KNOX?
If it does trip KNOX, it's not worth booting into TWRP, might as well just bite the bullet and install but only if bootloader is unlocked 1st... Too expensive to just brick it for an experiment...

personally I don't care about knox. I just want to be able to root and restore my apps so I can transfer my stuff from my s7 to the note 8 and freeze all the bloatware like touchwiz and stuff.
from what I gleaned from reading the threads is magisk makes a copy of the boot image as a backup.
but again I just want root and I can wait for a longer term solution in how to fix this moronic 7 day jail bs.
but I think knox will get tripped the moment you root

I didn't have OEM option as well (FRP lock was ON), I just followed me2151 guide but I was getting the partition error, so in first part I also added BL and after that everything went smoothly.
KNOX wasn't tripped, it's rooted as of this moment and tomorrow I will be installing custom rom.
PS: And yes it was an experiment but I was willing to take the risk because after reading half a day about no OEM option in developer options everyone was saying if it's not there you don't need it, I wasn't 100% sure but I was 98% sure I'm not going to brick it. btw I'm using Telus N950W note8 (locked)
I think you might want to be careful on that. I'm not sure who "everyone" is but the others like Dr.Ketan did not even recommend rooting without unlocking the option first and it seems to me that the general gist of the other thread (the 150+ page thread) was that you need it explicitly unlocked.
The ones who talked about not seeing the option means you probably don't need it are talking about custom roms (like renovate) that purposefully hid the option since it's already defaulted to unlocked on that rom.
I haven't used any custom roms yet, but that seems to be what I'm reading.

I was able to root it but the boot loader is still locked. It's faster without the bloatware and what not. KNOX is disabled. There is still no twrp and custom rom for Snapdragon to the best of my knowledge. It did change the model of the phone from N950W to N950U1.
finally got the OEM Unlock option and rooted + stock recovery... i had to restart my phone to bring my android ID back to the one I always used.. and got locked out...
so 7 more days for me. And all I wanted to do was to have Titanium backup up and running so i can transfer my phone over....
i am hating what samsung has done
I uninstalled all mods safely and correctly (took a **** ton of research to make sure I did it the correct way), totally unrooted and uninstalled magisk, re-flashed the stock boot and stock db-whatever files both to both slots.
Now I want to use google pay but I can't because the device has been modified--and I assume it's referring to its still unlocked state.
Is it perfectly safe to just lock the bootloader via fastboot? I don't know why it shouldn't be, but I've come across posts saying people have bricked their devices by attempting to re-lock.

I would flash the full image from Google not just the boot. You don't want to brick your phone. After that you will need to relock the bootloader to pass safety net.

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

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
