What exactly have you tried already?
Have you tried "fastboot flash recovery ***.img" ?
Of course, only the Nougat recovery will work.

Hmm command not allowed usually says that bootloader is locked. You did unlock it manually again right? Because it often is locked even though it says unlocked on the bootloader.

Nah that should not be an issue.
I don't know... Have you started fastboot with admin rights if on Windows?

I read a few arcticles, but still I´m not sure
I want Unlock my Bootloader and get to my zenfone 2 TWRP (is that mean Flash it? ) and then Root? (SUPERsu)
But I´m not sure what donwload for my version, and which ADB, etc, can anybody tell me more?
MY ZENFONE2 is
Zenfone 2 ZE551ML 16gb // 4 gb
Z00AD
last official update is .....Z00A-2.20.40.183

Unlock bootloader officially or unofficially. White ASUS Splashcreen will appear if unlocked successfully. Then go to bootloader then flash your twrp and now you can install customs ROM.
You can still root your device without unlocking bootloader or flashing twrp. Just download a pre-rooted firmware then flash using commands.

You dont need to be in the recovery to this, you just need to be in bootloader mode, connect your device to you computer then fastboot flash the parts of the pre-rooted firmware using fastboot commands.

Thanks, but I went with the one-click root and just unlocked the bootloader. I installed the Xperia rom and it's working really good. I've just waited to root this bish because I had to send it back to asus two times for repair " what a pain in the ****ing ass too "

Relocking Bootloader

Is there a way to relock bootloader? I tried flashing stock rom via TWRP but the prompt still shows that Device cannot be trusted blalbla unlocked.
Can anyone give me a way how to relock my BL? I also tried SRK tool with relock bootloader with my Unlock code, but it doesnt work.
Thanks
EDIT: Please lock thread. I tried locking via eRecovery and it worked. Thanks
Update your device. Use the full update rom like b161, 201 or whatever you like. That will remove the unlocked bootloader and root as well.

Yes is tested: at any update (via dialer or three key pressed) with stock firmware, you lose root, twrp and unlocked bootloader (if you have root, twrp and bootloader unlocked).

In my knowledge if u relock bootloader when u r in custom rom u will get some issues.
Also this boot message cannot fix in my knowledge. If u rooted then its not adviced to relock bootloader. Relock ur bootloader only if u r in pure stock and no root...
Unlocked bootloader needs for custom roms and root and twrp

Sorry i misunderstood your previous message, i understood that with root the warning would be gone.
I' m asking as newbie, can't we replace it with some other image, like they say on this thread?

Yes, you can. Required that you have the correct OTA update (fullOTA 3Gb+ package due to unlocked bootloader) and Stock recovery installed on it.
