updated link, sorry for the mistake

I use the STOCK ROM 0.78 ww
I'm with the unlock bootloader problem even in rom stock.
I lock bootloader again, and then use that?
It only works if you use custom rom? Or also in stock?

After I used it with Lollipop droidboot ww t00j stock .78 I had problems with camera. It works only with kitkat?

@ XHook
have you worked on method to re-lock bootloader..

bricked my bootloader
After flashing this I couldn't access my fastboot. Now I can't even boot to system. I'm stuck at the USB logo, where usually I could reboot to fastboot (via pressing Power & Vol +) to fix this. But now I can't even access fastboot. When I press Power & Volume Up, it shows a battery icon. Please do help @XHook.
Editted:
Sorry for panicking back there. I forgot the reboot to recovery way using Power & Volume down. At least I can still boot to my system. I'll try to find a DIY solution for this. Sorry for panicking, @XHook.

Your tool uses Fastboot of 4.3 version right? Is that the difference?

no more update? camera not found, can this method by xhook solve the problem?
i've tried this version, but make my bootloader missing/bricked, same with ezrawk post
Note : When I installed this version >> 3.24.40.87 latest stock lollipop firmware
@XHook, tell me what your firmware version when you install this UBL method.
Thanks

I was using a custom recovery (TWRP) at that time so I flashed a fastboot via install. If you aren't using a custom recovery, you'd probably want to check this out: Zenfone 5 A500CG, Zenfone 6 A600CG Last chance to debrick (This fix youre IMEI) by swiczak
About the flashable fastboot, try searching for it in the Help & Troubleshooting part, I think the user who upload the flashable fastboot zip was tank0412. Try PM-ing him. Sorry can't help you about this 'cause I forgot where I saved mine.
Goodluck!

Unlock bootloader without any bugs [Official method by ASUS]

Hi there,
I want to share with you a bootloader unlock method that worked perfectly for me.
STEPS:
Download official stock kitkat rom: ROM
Extract boot, fastboot and recovery from it and flash them from fastboot then flash the rom
Download official Asus tool for unlocking bootloader: TOOL
Install it and follow the procedure
If all goes fine when you switch on the phone the background behind the Asus logo is white instead of black.
It's easy and maybe a "stupid" method but it worked on my Zenfone 5 T00J.
The firmware listed in this topic is the only for me that allowed to use correctly the unlocking bl app.
If there are problems, I'm available :good:

do you have unlocker tool for zenfone 6 ?

My bootloader is alwery unlocked, but with black background, now I unlocked with this and its white, great , I was tired of that bootlogo

Works the same as all other methods, doesn't fix "freeze" or "no camera" issue...

HELP! Re-locked Bootloader...No Recovery...No System....No Boot...NOTHING

SO I made a n00b mistake and accidentally reloacked bootloader trying to flash a fresh system image. I wanted to go back to stock after being rooted and unlocked.
Now i get the red screen of death and it just shuts off the phone. No recovery seems to be installed.
What do I do? Do I throw it in the garbage? Or is there a way to salvage this device?
Bootloader is locked and will not let me unlock again.
Thanks.

I don't have the Pixel, so I'm going off of what I know from the 6P.
Does the Toolkit work for the Pixel? There has to be a way to get it working if you can get into bootloader.

I am not sure. I think I need Unlocked bootloader.

Actually i think you just need to reunlock using depixel8. That should unlock your bootloader and allow you to flash new firmware

Did you try using dePixel8 to to unlock your bootloader back? I would try that.

You have to be booted in Android for dePixel8 to work.

Am I missing something? why can't you just flash factory image again from the bootloader and then unlock your bootloader with the depixel8?

He said that he tried to unlock the bootloader again and it won't let him. With a locked bootloader, you can't flash the system images.

My mind is blown on how you accomplished this. Did you ERASE the partitions and then plan on flashing stock ones yourself? Why not just run the script (flash-all.bat) that would have automatically done the ENTIRE process for you, except re-locking the bootloader?
If all you did was re-lock the bootloader, it should have done a factory reset on the next boot and used the existing system partition. If you erased the system partition and then re-locked the bootloader, you are almost certainly screwed and had better hope Google has some mercy to let you RMA the phone.

Couple options you could try off the top of my head. The pixel has A/B patitions try adb sideloading an update zip to get it to switch to the backup partition that might still be there.
You could also try downloading the Factory images and extracting the system and go into fastboot and type
Code:
fastboot boot system system.img
and see if that works. Then if it boots on the temp image run deadpixel8 or whatever its called and reflash the stock image with the flash-all.bat.

have the same problem on my pixel after accidentally relocking after root before flashing back to stock.

Does anyone have the stock pixel xl recovery.img? I thinking if I boot into recovery "fast boot boot recovery.img" then I can add side load etc the ota from google.

Phone stopped working for no reason - can only get as far as the bootloader now

Tried looking through threads and have spent all day trying to fix it.
Phone was working fine a couple days ago until it ran out of battery. Since then nothing.
If I try to turn on normally I get stuck on the Google screen. Only other thing I can do is boot into fastboot/bootloader but from there, if I try Recovery mode it sticks in a bootloop

I think you have a hardbrick bootloop, There is fortunately a kernel and recovery developed by developers to overcome this problem, but you'll need a unlocked bootloader as it involves flashing recovery and boot.img. If you have boot loader unlocked, go to general section where you'll find a thread regarding the same. All the best

I tried that - flashed the recovery but when I try to launch recovery mode I just get a bootloop again.

broken TWRP Recovery and locked bootloader

Hello guys, I'm on LineageOS. I want to go back to Oxygen OS. But I can't because of my locked bootloader.
I did try to connect with the pc via adb: "Fastboot flash recovery recovery.img" and it's says everytime bootloader is locked enable OEM. I know the OEM is in the Developer Options but not for me. It's not available.
What to do now?

Code:
fastboot oem unlock
It will wipe all of your data.

Yes, that means it's not enabled in developer options.
Now you say you don't have that OEM option available in the developer options - are you sure you've turned developer options on? If not do as @gorillaCF says above.
If you have done that and still don't have the option then back everything up, do a factory reset and try again immediately after that.

do that.

LineageOS 15.1 doesn't have the OEM unlock feature. Normally, if you temper with the system and lock the bootloader it won't boot at all making this option useless. At least that's what I've experienced. As others stated you can only use the unbrick tool which will definitely work or contact OnePlus for an L2 technician who will use the same tool to do so.

So how did you do this? Did you do "fastboot oem lock" with TWRP and LineageOS on the device?

Why the hell LineageOS 15.1 don't have the OEM unlock? This makes no sense, because now I have a big problem.
Yeah, the unbrick tool I'm lucky but for the others with different devices will not have this unbrick tool. That's very stupid. It will be last time for me, with LineageOS.

Normally, it is impossible to lock it without fastboot. Again, it's not LOS's fault. You should never lock your bootloader if on a custom ROM or modified system. I've been running LOS 15.1 for almost a week and never had such an issue.

Sorry sir, but the factory Images means stock ROM and stock recovery.
Can't flash both
Why there is no backdoor for this situation? Why is this not possible, that you need by Factory images no unlocked bootloader. That would fix many problems.
