Can I lock back the bootloader in my Galaxy Nexus to go back to stock?
locking the bootloader does not return you to stock. you need to flash the stock rom via fastboot to return it to stock.
If you want it lock up again use ''fastboot oem lock'' command.

Will this return the stock recovery?

no. nothing about locking the bootloader returns anything to stock.
the only thing locking the bootloader does is:
1) remove the lock symbol on the google bootup
2) no longer allows flashing of insecure images.

You get the stock recovery with getting the nexus image and flashing with ''fastboot flash recovery recovery.img''. So basically getting a factory device is with downloading the image, doing the flash-all and fastboot oem lock at the end.
ah ok, thank you all
Edit:
Zepius, I followed the guide in your signature. It was painless, thanks

Instructions are a bit wanky. You need to be in download mode for the instructions to work. Had similar issue.

I tried going into download mode and then doing "fastboot boot recovery.img" so that I could take a nandroid in it's current stock form before flashing the TWRP recovery. All i got was a "Start Downloading" Prompt and when I'd select it, the device kept saying "Under Flash" over and over again. Any idea of what to do or do I have to take the plunge and flash the boot with the recovery image?

you can't boot recovery
you need to flash TWRP 2.8.6.4 beta
Make a nandroid and save it to your pc
In TWRP Terminal use this command
Code:
mount -t ext4 /dev/block/bootdevice/by-name/system /system
Reboot recovery and your ready to start flashing SuperSU / roms

Captain_Throwback said:
8. How do I backup stock recovery prior to flashing TWRP?
You can't. The "fastboot boot" command appears to be disabled on the M9's ABOOT, so TWRP must be fastboot flashed over stock recovery. The firmware zip included in the OTA will include a usable stock recovery image. That can be extracted and flashed after stock system is restored so that the OTA can be applied.

You need to be in download mode to unlock the bootloader.
Follow this guide by KingInTheNorth to unlock your bootloader and root.
Just a small note: if you're on a 5.1 stock rom, you need to enable OEM unlock in developer options first.

As long as its not a verizon branded phone, you may be able to unlock it at www.htcdev.com/bootloader.I say may be because im not sure about a demo device, and whats different on that than a regular phone.

the difference is that i can not store any data in the phone. the app named "demo" keeps popping up automatically. and when it does my all data is gone like my contacts, messages, even the pictures.
in settings there are some option which i can not change, like i can not lock the phone or enter in the security section.
The phone is international version, i tried to unlock it from htcdev but for that u must be able to enter in FASTBOOT nd that OEM option in developer setting must be enabled. i am not able to enter any of those. No fastboot option in Settings. nd when i boot to Bootloader mode there is no option like fastboot. i hope this will make u understand what im trying to say! thannks
I dont know if its a demo thing, but general m9's dony even have the oem option in developer settings. There is no fastboot option to select in the bootloader, you just use a cmd prompt on your pc while in bootloader to type fastboot oem get_identifier token. Mabey i still dont understand.
In settings - display and gestures look for daydream and see if it gives you the option to shut it off. Or go to manage apps find daydream and see if you can disable it. I believe demo mode is part of daydream. Also may be called basic daydream. Also look for any other apps that say demo and try to disable them.
I can't run Nexus 5X after flash stock firmware.
Phone restarts when is boot animation.
I have locked bootloader.
Please help
reboot to fastboot, use a computer with fastboot drivers and use the following commands...
fastboot format cache
fastboot format userdata
And NEVER uncheck that "allow unlocking" box

Thank You for answer but I can't do this because I have locked bootloader.

Have you tried a factory reset from the stock recovery?

bootloader does not have to be unlocked for those commands.
Once you try the above suggestions, download the latest OTA and ADB sideload it. No unlocked bootloader required. The instructions on how to sideload are on the download page.

uhm, from what I remember from the Nexus 6 brick disaster due to locked bootloader + disabled OEM unlocking + fail OTA, people were claiming that they couldn't do those 2 commands either with a locked bootloader.

I haven't tested with the latest bootloaders, but I thought I recalled you couldn't do any write operations through the bootloader when it was locked.
Thank You
Thank you all for your answers, I will give tomorrow to repair. I will answer when I get it back and write what was the cause.
They gave me money for the phone, topic is closed.

Today i manage to relock my bootloader, but clean all and lock option can't relock it. It only put my phone on stock condition with stock recovery and stock rom, just as same as clean all option. To relock bootloader, i use fastboot command "fastboot oem lock". Hope it can help whose want to relock bootloader

Did you do any modifications on your phone like root?
If so, you'll need to restore to stock either with fastboot ROM or MSM tool, the lock the bootloader.

how do i restore to stock? please help me
is it safe to just relock normally in fastboot via command prompt if ur on beta 2 one plus ?? Do i need any files to do it ? except adb etc...
If You did not messed with Rom it will be ok, but if You root it, first You need to go back to stock rom
Will the phone boot after relocking with a custom rom without root?
If You are full stock, stock rom, fastboot, all is stock, You should lock bootloader with no problem.

FASTBOOT OEM LOCK and the problem with some app dispear and your phone run like factory as normal.

Got my HD1905, unlocked bootloader (no root etc. Only to be able to use TWRP, just in case) and installed my apps. Then I noticed the Netflix problem with unlocked bootloader. If I do a 'fastboot oem lock' now, I'm pretty sure it will do a factory reset, correct?
