I have read all of the info about unlocking and relocking the bootloader, but i have a question, if i was 100% stock with a locked bootloader and wanted to flash the latest factory image would i still need to enable developer options and enable allow oem unlock even if i was to run the commands below from fastboot mode.
fastboot oem unlock
fastboot flash bootloader bootloader-shamu-moto-apq8084-71.08.img
fastboot reboot-bootloader
ping -n 5 127.0.0.1 >nul
fastboot flash radio radio-shamu-d4.0-9625-02.95.img
fastboot reboot-bootloader
ping -n 5 127.0.0.1 >nul
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot flash cache cache.img
fastboot oem lock
fastboot reboot
The reason i ask is that you are not booting into android until the bootloader is relocked, so in theory the oem unlock option shouldn't have an effect in this scenario?
@d.chatten,
Yes, you have to unlock the bootloader to use fastboot to flash .img files, or to sideload via ADB.

You really should boot into Android before re-locking. This is where people have run into trouble. Following the re-lock guide is recommended.
Thanks for your reply, much appreciated, but my question wasn't about the need to unlock the bootloader ot flash, my question was, do i still need to enable "allow oem unlock" in developer options if i use the commands listed above when flashing the latest factory image on a Nexus 6 when 100% stock a locked bootloader, this in theory should work as you are not booting into android until the bootloader is relocked?
The main thing to remember, is to remove all security locks and your Google account beforehand. With this device, when fastboot oem lock is issued, the device is wiped again. This is why it is important to be sure you have a working OS before locking. :good:

I understand completely. In a sense, you have outlined the process that is shown on the factory image page, by Google. This information needs to be updated as it does not reflect the security changes made in 5.1. I wouldn't risk your device for a few extra minutes needed to verify the OS boots.

I can confirm that several people have bricked by trying to do it the way you were thinking of trying. If for any reason, during the flashing process something didn't flash just right, and a bootloop occurred, you wouldn't be able to fix it with a locked bootloader. That's why it's best to ensure your OS boots before locking.

Thank you for clarification, much appreciated, the process is still easy enough even with these extra steps.
Hey,
I would like to go back to stock from unlocked + root.
What is the correct way to do it?
Little tutorial would be awesome also for other users I think.

will that lock bootloader again?
To lock the bootloader you can either use the tool (which has the option to lock) or do it manually with the commands
Fastboot oem lock
Fastboot flashing lock
And finally
Fastboot flashing lock_critical
Be sure to flash stock before locking the bootloader, otherwise you may end in a bootloop.

You only need to lock the last two if you unlocked them.
Hello,
Im trying to relock my bootloader again, did i just have to use the "fastboot oem lock" command? Because i read it somewhere that i have to flash stock rom before locking the bootloader, if yes can someone give me the link for stock rom and how to flash it, FYI when unlocking im only using "fastboot oem unlock' command, not doing "fastboot unlock critical blablabla".
Any help would be appreciated, thank you
as far as i know, you need to flash stock bootloader of your current android build then uninstall magisk (if you have it) and just use fastboot oem unlock and you're done (note! backup all your data cause it will make a full wipe)

I stopped after unlock bootloader only, i didnt root it at all, so you mean after flash just run fastboot oem lock command?

Yes. It will wipe your data. Please becareful.
Oh. Please sure that you have back to original boot image before relock or your device will brick.

I never relock bootloader .. what I know is you must have fully stock ROM installed then only advisable to lock bootloader. Never do on rooted stock & custom ROM.
Maybe someone else can advise you better.

"Fastboot oem lock" seems to be depreciated for Mi A2, better use "fastboot flashing lock" instead of "OEM unlock" (though probably these are still equivalent).
And yes, full unlock is achieved when after general unlock you are unlocking critical (once more approve on phone, once more user data erased).
For your information. I've just bricked my Redmi 10S with stock ROM with the command ""Fastboot oem lock" :-(

I relocked my oem and cant unlock it again. Says feature disabled
Tried potting and restocking but its not flashing because of oem being locked.
Any Ideas?? This is my first rooted phone and I’m new. I had magisk installed earlier but had to reinstall due to android system apps like media storage crashing.
Thanks

You should download the stock firmware from here and following this guide to restore to stock firmware. Even if the rest of the commands don't work, the first two should reset the bootloader and partition tables and make it bootable or maybe unlockable again. You can also maybe try to boot TWRP but I don't know if that'll work because the boorloader is acting odd

You should be able to flash official firmware even if the bootloader is locked. Do you still have the original unlock key you received from Motorola to unlock the bootloader? You'll have to use that to re-unlock your bootloader.
Code:
fastboot oem unlock UNIQUE_KEY
Replace UNIQUE_KEY with the unlock key you received.
EDIT: It just occurred to me that "OEM unlocking" is probably toggled off since you re-locked the bootloader. That's why it says "feature disabled".
You could also try to restore stock firmware using Lenovo Moto Smart Assistant. It has a Rescue option that does that.

I heard that once u relock bootloader, your unlock feature gets disabled for a few days. Anyone know if that is true?

I'm pretty sure it's because the bootloader can't contact the OS correctly and therefore can't validate the request

You need to enable bootloader unlock through setting in developer option enable oem unlock, and then you can use the ' fastboot flashing unlock'
You can't root with locked bootloader as it will show an error message your device is corrupt,
At you situation now you should flash stock boot and then the phone will open and then you go to settings as i mentioned to enable oem unlock through developer option in settings
Fastboot unlock bootloader with long command, you will see it unlock temporarily till reboot, flash boot.img and recovery.img, reboot into recovery wipe data & cache, utilize USB otg to reinstall rom.

Use "Fastboot fastboot oem nubia_unlock NUBIA_NX629J" to unlock the bootloader and flash the correct boot img. Or you can go to stock recovery flash the whole system. It is caused by an unsigned boot file.
