If that doesn't work, you're in the line of people with similar problems, looking for a way to restore bootloader with nvFlash.

Sounds like you may have to reflash a complete stock factory image, including your bootloader. Those threads should be of help.

You should start over completely and make sure you have the right factory image and that all partitions are formatted etc. Start getting it to boot with stock image and locked bootloader, and take it from there.

I can't seem to unlock the bootloader for some reason

I'm not an Android rooting noob (my rooting goes back to OG Moto Droid in late 2009) and I'm sure it's something ridiculously simple I'm missing but I can't get my bootloader to unlock. I've tried ADB/Fastboot, WUG's Nexus Root Toolkit, and Chevy's Android Job Box. Nothing works.
I got my 6P today, SIM'ed it up, booted up, logged in, enabled USB debugging, installed the drivers, and let it update. When I opened WUG's NRT, I saw that I had an Android build one step later than the NRT. Mine's MD80BL and K is the latest in the NRT. I thought that shouldn't be a problem and selected the "any build" option with the Nexus 6P. I went through the installing drivers process and can access the file structure of the phone through W10.
I then went to the unlock bootloader option, clicked through the prompts until the phone rebooted into the bootloader and clicked the OK button to unlock the bootloader. About two seconds later a window popped up on my desktop telling me my bootloader was unlocked, my data was wiped, and I would have to go through the setup process on the phone. Excellent, except my phone booted right back to my stock homepage. I tried again with the same result.
I then tried it manually using ADB/Fastboot. The "fastboot devices" showed a connected device which I assume is my 6P since I have nothing else Android connected. When I type in "fastboot flashing unlock" I get all the fastboot commands/options as if I typed an unknown command. "Fastboot oem unlock" didn't work either. I went and downloaded the latest SDK and retried everything with the same result.
Here's my Build Number.

Here's what I get when I try to use fastboot to unlock the bootloader.
Any help will be much appreciated. I expect I'm going to feel stupid when my mistake is pointed out but I'm here to learn.

Upgrade your adb/flashboot setup. Probably too old.
You must allow the option to unlock, then go to fastboot, the run the command, with an updated version of fastboot command.

Ah, I see. The SDK Manager is not installing into my SDK directory. I'll copy/paste, retry, and report back. Thank you!

Now I get this message that unlocking the bootloader isn't allowed.

Go to developer options & turn on the option that says enable bootloader unlock and retry.

Ha! I do feel stupid.
Thank you very much!!

You are very welcome!!!

ASUS ZE550KL - My phone is the god to failure =]

Hello everyone,
First of all, I apologize if this post is in the wrong section. Also I'd like to say how awesome it is everyone that is involved in these projects.
My Issue is I can't get ANYTHING to work, I have tried so many roms that apparently work for my phone and I always, foot errors, signature errors though the adb. I have tried every program to unlock bootloader but apparently does not work unless you are running V2 551 2.40.*.* so I went and downloaded this, and wants again can't flash the ROM. The unlock bootloader was weird, I went through all the installation and I don't even know if it worked to be honest. I can boot into the phone via power and volume down, and get a menu that includes, apply apps from ADB, wipe/restore phone, fastboot mode * which goes as far as my phone saying *FASTBOOT !!!* then thats it will not continue. The power and volume up does the same thing. So basically I'm starting to think this piece of crap phone will never have a decent operating system on it. The phone is in developer mode and USB debugging is on also. * Basically have done every single tutorial I can find and nothing works*. Also the twrp doesn't even work. I have even tried flashing back to an older version on the phone and get the same ADB errors. I have installed all the ADB and also minimal adb and fastboot and all drivers for the phone as well. * TRYING NOT TO MISS ANYTHING*
My phone specs:
Model: ASUS_z00LD
Android: 5.0.2
Baseband Version: 202c10_10.0.0_160120
Kernel: 3.10.49-gec27b65

Did you try to unlock bootloader the official way? I myself unlocked the ZE550kl following this thread http://forum.xda-developers.com/zenfone-2-laser/general/ze600kl-official-bootloader-unlock-t3273263
You can check if bootloader is lock or not from fastboot by entering "adb>fastboot oem device-info" should show up somewhere between the lines "Device unlocked: true"
After unlock only then you can install Official recovery TWRP 3.0.0-0 from here http://forum.xda-developers.com/zen...recovery-twrp-3-0-0-0-touch-recovery-t3317513 .
If needed TWRP will also help you root your phone once is installed.
Good luck!

Need help, after downgrade and official update

Folks, after a successful downgrade to 6.01 and re-lock the bootloader, i can install all ota's, but the one thing is, that the device will always stays on bootloader after reboot. Right now, i am on the latest MM and will update now to N. Everything works fine. This device must be locked.
I need manually press "START" to reboot into system or recovery mode.
I want to stay on originally software. How can this issue be fixed?

Try connecting your device to your computer, then whilst your device is at the bootloader, in the adb terminal on your computer type 'fastboot oem fb_mode_clear' (without quotes). This may allow your device to reboot properly.

Good job, works, right now
After the latest update to 7.0/NPJ25.93-14/16 it shows instead logo, ID=Bad key, this device is unlocked bla bla bla, but it isn't. Once i did this serveral month ago, it works but not now. MM does not shows a bad key.
i know i can flash a logo to cover this but it should be in original state. Screenshots follows_

My oem unlocking option is grayed out...earlier i have tried to unlock my phone that time i am able to turn the oem unlocking option on but due to some problems my phone got stuck in the boot screen ...i gave my phone to service centre after i got my phone i saw that my oem unlocking option is grayed...now what to do? I am usi]ng moto g5 plus please help!!

The only reasons OEM unlocking is grayed out is either you are already unlocked, or they installed an engineering bootloader... Better hope it's the first one, because if it's the second your in trouble. What is the output of "fastboot getvar all" (and mask out your IMEI)?

Engineering bootloader? What's that?

It's a temporary bootloader used by Moto Support/Repair and service centers when flashing back to stock after a failed update or corrupted ROM for some other reason, it allows them to unlock the device at a deeper level than normal, flash what they need, then relock the bootloader without tripping the warranty flag, then restore the stock bootloader.
It has happened a few times where a device has gone out with a Engineering bootloader (google it, you will see a few threads here and there) back to a customer after a repair, the problem is it's not really unlocked, you can't flash TWRP or custom ROM, and it can't be relocked or fully unlocked (we don't have the code required, guessing it's similar to a regular bootloader unlock code, unique per IMEI, but different). It is seriously annoying and the only solution is to send it back to Moto or return it to the service center which may or may not be able to rectify it. On a good note, the device will function on the ROM installed. We don't know what will happen if you attempt to take an OTA though.

Than you're probably unlocked already?

Restart the phone - do you see a screen with a yellow triangle with exclamation with a statement your bootloader is unlocked.... If Yes, your phone is already unlocked.
