Good news that this is available! Thanks to the OP!

Question though, and it may be too soon to tell (maybe not - this is the second version with this ability)... does OTA still work after unlocking the bootloader? Has this been tested?

Since we cannot be rooted to receive an OTA, I'm curious if this would become a roadblock in the future as well.
[ZenFone 2 General] Harfainx:
OTA will work with unlocked bootloader if you're on stock recovery, all the system apps are present, and you aren't rooted.

Unlocked bootloader won't change that.

OTA won't work if you flash TWRP. You'll need to wait for a flashable OTA.zip

---------- Post added at 12:49 PM ---------- Previous post was at 12:47 PM ----------

If you already unlocked, that will always be there. It's not a bug.

It's telling you to continue fastboot. Nothing to fix.

hi, i'm using ze550ml with 2.19.40 rom. after rooting it, adb shell, su, getprop ro.isn > /factory/asuskey, my phone boot to fastboot with 'can not get the necessary info 2', bootloader status = unknown, sign = ?, secure = ?, and after that, restart to normal mode, but splash screen still black. am i missing something, or is it done? sorry for my english, thx in advanced :)
[ZenFone 2 General] -fluffy-:
Splash screen will become white wen it unlocked if it stay black u are not unlocked

my ZE550ML looks the same, but still able to unlock the bootloader and install TWRP, so not really a problem ;)

---------- Post added at 09:57 PM ---------- Previous post was at 09:51 PM ----------

try installing "Terminal Emulator" app and running the commands from there:

su

getprop ro.isn > /factory/asuskey

reboot bootloader

this worked for me I was also having issues running adb shell from my windows PC, so just did it directly on the phone :p
[ZenFone 2 General] abelavila:
hello good I not understand English, and I would like to know how to set this up? I need Windows to follow step ??
[ZenFone 2 General] sorg:
This is nature of 2.19 fastboot. Everything works fine. You can flash old fastboot (from 2.18 for example) and u will see old "fastboot cmd waiting..."

I didn't see this text, because usually i use batch file which start to do something as soon as phone enters fastboot.

I got TWRP installed on my ZE550ML. Hoping a build of cyanogen will be released for both models of our device soon. Props to the fantastic devs who have made root, bootloader unlock and custom recovery possible so far - thanks guys! And have to say what a great Android community to be part of XDA is - so many people able and willing to help out other members with less knowledge or with difficult problems, and little or nothing of the trolling, flaming and general unpleasantness that occurs on many other forums! Thanks all!
[ZenFone 2 General] Shafwan7:
what is the advantage if i unlock the bootloader?
[ZenFone 2 General] fuzzybuffalo:
You are then able to install custom recoveries and custom ROM's.

but we are still not have custom roms.. so maybe i'll stick with locked BL first. hehe

I am thinking of unlocking finally. I am rooted successfully on 2.18.40.12. I copied the 2.19.40.18 file to my phone and ready to start. Do I need to unroot before installing 2.19 or am I safe? REALLY happy to finally start.

[ZenFone 2 General] lovemyram4x4:
Unlocked bootloader and also installed TWRP in terminal emulator. Can't believe how easy it is to unlock bootloader on this phone, much quicker and simpler than both official and unofficial ways on my other phones.

I just wish I'd remembered to uninstall xposed before applying the 2.19 update:o
[ZenFone 2 General] amdhunter:

I had the same problem with fastboot on Linux not recognizing the Zenfone 2. I downloaded the barest install of the Google Android SDK, and then installed the utilities and the fastboot that downloaded does work under Linux with the Zenfone 2.
[ZenFone 2 General] Deadnight93:
If I update to 2.20 version (out in a couple of days) without bootloader unlocked, can i unlock after that or not?

Also if I update to newer version with bootloader unlocked... it produce any problem for example relock it or bootloop etc?

Inviato dal mio Nexus 7 utilizzando Tapatalk
[ZenFone 2 General] Harfainx:
They may patch the method of unlocking in future versions. We can't know that until it comes out.

If you do unlock, it won't make you bootloop on update. Having SuperSU and the binary updated will currently make you bootloop on update, but the state of the bootloader will have nothing to do with that.

You also can't OTA if you have TWRP installed, so there's another thing to consider.

When OTAs come out, I'm sure we'll have safe versions ready to TWRP flash pretty quickly. Shouldn't be a problem.
[ZenFone 2 General] aaronoh:
Is there any confimration that 2.20 is out in a couple of days?
[ZenFone 2 General] kanagawaben:
With TWRP installed, will we be able to flash the full ROM (via TWRP) when ASUS make it available (usually a couple of days after the OTA)?
[ZenFone 2 General] Harfainx:
Yeah, just need to remove the getprop and asserts in the updater-script. Quick easy change.
[ZenFone 2 General] Deadnight93:
Thanks! I don't want to install twrp at the moment... But in future maybe

If bootloader unlocked don't produce any problem to fota, I unlock it before Asus block bootloader with next update!

So if you are sure tell me [emoji4] [emoji4]

ZE500CL

My phone does not have an asuskey file inside the factory folder so i'm gessing i cant unlock my bootloader, that really sucks.
[ZenFone 2 General] Harfainx:
Yes, as long as you aren't rooted. Flashing OTA over root causes it to hang on boot.

Who knows what might be in the update though, so you'd be on your own if something broke on OTA.

Which phone are you using? Are you on the newest build? 2.19?
[ZenFone 2 General] StuffiLike:
As I said I am using a ze500cl. The little guy. Only the two models above seem to be unlock able. This really sucks.
[ZenFone 2 General] klashn:
Thanks for the tutorial.

I used the fastboot method to load the image files, then unlocked the bootloader.
[ZenFone 2 General] fuzzybuffalo:
First, Titles do not show up in Tapatalk, so anyone reading your post from above, in Tapatalk, would have no idea what phone you are using. See screenshot below.

Second, The important thing is if the 500cl has the 2.19 update, without that, you can't unlock the bootloader anyway.

Third, My 551ml with unlocked bootloader does not have the asuskey file in /factory either. Not sure, but I think that command creates a temp file to unlock the bootloader.

It's something to do with the /etc/firmware/if.bin file and before you ask, I'm almost positive you cannot just copy it over.

Well you wouldn't be using adb if you're on your phone.

Also, you're not rooted, or else it would find su.
[ZenFone 2 General] dsplvd:
The 'adb shell' command is for opening a shell through adb link, with your phone connected to your computer with a USB cable. In this case your are opening a shell in your phone, so it's not needed.

The 'su' command is to use superuser commands. You don't even have rooted your phone. Please read and follow the first post instructions carefuly.

but still I have a problem with the recovery: after unlocking the bootloader I can't enter into recovery mode. anyone can help?

See more details in my post here.
[ZenFone 2 General] Harfainx:
So you are unlocked? White splash screen?

Did you flash the twrp.img or a recovery.img? If you can't get into recovery at all, such as it keeps rebooting to bootloader... You probably flashed a bad img to your recovery partition.

If you're unlocked, go to the TWRP thread and download the twrp img. Then flash that as your recovery. Then when you reboot to recovery you'll see TWRP.

Or if you want the stock recovery, flash a stock recovery img.
[ZenFone 2 General] devidart:
Splash screen is black. I tried many times to enter:

adb shell (press enter)

su (press enter)

getprop ro.isn > /factory/asuskey ( press enter)

reboot bootloader ( press enter )

in cmd and in terminal emulator. You can see cmd logs in my first post.

It seems that "getprop ro.isn > /factory/asuskey" does not work because after entering "reboot bootloader" the phone restarts in bootloader and there is no more action after .

I tried twrp.img, twrp_ntfs.img many times. Where can I get stock recovery?
[ZenFone 2 General] Harfainx:
You flashed the 2.19 system.img? Did you flash the 2.19 fastboot.img? Are you rooted on 2.19?

You must have 2.19 system and fastboot, and also be rooted before you can complete those commands.
[ZenFone 2 General] devidart:
I have 2.19 OTA (I did not flash, it is auto update through wi-fi). root is ok.

I must personally flash system and fastboot?

How can I check version of fastboot? In the screen I can see "bootloader version: unknown".
[ZenFone 2 General] Harfainx:
When in doubt, just flash the fastboot from the 2.19. That will make sure you're good.

Hello,

I am currently having issues unlocking the bootloader.

So I type all the commands and give root access to adb shell, however after it reboots into the bootloader, it just stays there and doesn't do anything.

How long am I supposed to wait before the bootloader reboots? (into the white splash top screen)

I am currently running 2.19 and am unsure of what I could be doing wrong.

I have also tried doing it on terminal emulator.
[ZenFone 2 General] trnscnd:
Are you just sitting in the boot loader or have you rebooted?
[ZenFone 2 General] OfficerJimLahey:
For me (memories from today), it took a couple seconds before the automatic reboot.

Which 2.19 are you using? 2.19.40.18 which was released two-three weeks ago, or the new 2.19.40.20 that was released today?

There may be a significant difference. The old 2.19 was pulled from OTA duties by ASUS because it can unofficially unlock the bootloader, whereas the new one probably has that hole patched, thus unable to use that exploit.
