Released on asus website 14/12/2015:
Marshmallow:
http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZE551KL/UnlockTool_ASUS_AndroidM20160928_Singed.zip

Lollipop:
http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZE600KL/ZE600KL_UnlockApp.zip

The APKs for each are binary identical, so it is not really important which unlock utility you download.

Frequently asked questions:
Q: will this work on ZE500KG / ZE500KL / ASUS_Z00RD / ASUS_Z00RD_5 / ASUS_Z00RD_7 / ASUS_Z00ED / ASUS_Z00EDB / ASUS_Z00E_1 / ASUS_Z00E_2 / ASUS_Z00E_3
A: we do not think so, but we do not know if anyone has tried it.

Q: can I relock bootloader?
A: we do not have a way of re-locking bootloader right now. Hopefully it will be possible using a backup of some partition to restore original bootloader, but we have not found it yet.

Q: can I restore my warranty by re-locking the bootloader?
A: we believe that ASUS records the serial number of the device through the unlock utility, so it will not be possible to make a warranty claim even if you do manage to re-lock the bootloader.

Q: can I still receive OTA updates?
A: we do not know, because no updates have been released since the unlock utility was released.

Q: can I still update firmware manually?
A: yes, definitely. fetch the new firmware zip from ASUS website and flash in stock recovery or transfer to root of sd-card and boot the phone normally (it will find the update zip file and prompt you).

Please note, I have ZE550KL-1A025TW version, Snapdragon 615, 2GB RAM (ASUS_Z00LD / ASUS_Z00L_93)

I updated my ZE550KL to firmware v1.15.40.771:
http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZE600KL/UL-Z00L-WW-1.15.40.771-user.zip

then ran the ZE600KL unlock utility.

Unlock utility runs without errors, phone reboots, no errors, everything still working fine.

Confirmed unlock successful

Code: 
C:\adb>fastboot oem device-info
...
(bootloader)    Device unlocked: true
(bootloader)    Charger screen enabled: false
(bootloader)    Display panel:
OKAY [  0.010s]
finished. total time: 0.010s

Can someone please paste the output on a rooted ZE550KL in adb shell:
Code: 
ls -al /dev/block/platform/dw_mmc/by-name

I already compiled a cm recovery, but i am not sure about the block names...

Moreover, can somebody please upload raw backups of the 'aboot' (& 'abootbak' if present) partition before & after unlocking the bootloader? You need root access & can use something like this one.

fair enough. How do it look? The 600KL is a 6" phone and the 5500KL a 5.5". Does it appear to overlap or anything?
Click to expand...

looks normal, both have same resolution. I think both phones use the same firmware since the kernel is identical and Asus don't release Z00m firmware but use Z00L for both models.

@Titokhan must be too late for me to do this, since I already unlocked and have no way to get back?

attached is aboot and abootbak after unlocking, maybe @heywheelie can upload the before?

    Okay, from root (#) command prompt:
    Code: 
    dd obs=1 count=1 seek=16 of=/dev/block/bootdevice/by-name/devinfo

    Then reboot and see if it unlocked it.
    Click to expand...
    @Titokhan and osm0sis
    OMG OMG OMG IT WORKED!!!!!!!!!!!!!!!!!!!!!!!!!
    I had to do one more thing before your byte flip
    "Adb enable" should be set to 1. But by default, we don't see "adb enable" line after exec "fastboot oem device-info"
    When I executed the following, only then i could see "adb enable : 0" in device-info
    Code: 
    fastboot oem abd_enable
    Then exec above command again, will set "adb enable" to 1
    And then your magical code
    Code: 
    dd obs=1 count=1 seek=16 of=/dev/block/bootdevice/by-name/devinfo

    Here's the imp terminal output (attached complte output)
