REPORT: This does not work on ZD551KL (Selfie) with Marshmallow ROM
[Zenfone 2 Laser General] Nubanuba:
This must be on the front page, if OP reads this, please add it to clarify:

guys, the unlock bootloader only works on specific versions, for example on my ZE550KL it ONLY WORKS on 1.16.40 and not on ANY OTHER VERSION, so if you want to unlock your bootloader, first check which version your cellphone has to be, update or downgrade your smartphone to the specific version and then (and ONLY then) you can unlock your bootloader!

[Zenfone 2 Laser General] 24imelqui:
Make sure you are connected to the internet. Before flashing twrp make sure you are unlocked. Go to fastboot, type

fastboot oem device-info

If you see "Device unlocked: true" it means bootloader is unlocked!

[Zenfone 2 Laser General] Mudy45:
Technical problem with ASUS official bootloader

The ze601kl official unlock-er (and probably other Zenfone Laser's) is looking for following ASUS servers that is not running. Its probably causing "network connection issue" problem.

"mdm dot asus dot com/DMServer/DeviceState"

"mdm1 dot asus dot com"

"122 dot 146 dot 44 dot 128:8787"

I think users need to remind ASUS to turn on their servers or change the unlock-er checking mechanism. Those who made it probably at the time when the servers running, that explain why some people managed to run the apk.

It is regrettable that data collection become the reason users facing so much difficulties. Bad corporate habits.

Some guy made an unofficial unlock-er for ze500kl but not for other zenfone:

how-to-unlock-bootloader-zenfone-2-laser-ze500kl-marshmallow on asus blog,

With following:

# Offset

oAndroid=5242368

oUnlock=5242384

oTamper=5242388

oSSN=5242408

oUnknown=5242496 # always set as 01

# Byte length

lAndroid=13

lSSN=12

# String

sSSN=$(cat /dev/block/bootdevice/by-name/asuskey4)

sVersion=$(cat /dev/block/bootdevice/by-name/asuskey3)

sAndroid='ANDROID-BOOT!'

then write the dd stuff

Its great because he also provide re-lock script.

"In order to update your firmware to MM one you can either flash ASUS MM rom in stock recovery or flash a package that will update your fw which you can download right here"

Download that link, sideload it with no issues and lineage OS 14 with no issues.

[Zenfone 2 Laser General] sukhoi47:
I tried to root/unlock my Zenfone 2 Laser (ZE551KL) without success so far.

The firmware seems triggered a bug and, as a try to fix, I want to do a downgrade on the firmware or install Lineage OS. For that I have to unlock/root to install TWRP.

Now it is running Android 6.0.1 with firmware WW_21.40.1220.2181_20170805, received via OTA update.

I tried Kingo Root, Dr.Fone (by Wonderware) and the official unlocker by ASUS for my device (UnlockTool_ASUS_AndroidM20160928_Singed.zip).

The Asus unlocker shows the error message:

"An unknown error occurs, which may be a network connection issue. please wait and try again later"​

Any idea about how to get it rooted/unlocked?

[Zenfone 2 Laser General] billysam:
Needs working Internet connection
[Zenfone 2 Laser General] camseye:
I was also facing that problem, you have to downgrade to lolipop for unlocking the bootloader and for gaining root you have to flash twrp through fastboot and then flash super su or magisk.
[Zenfone 2 Laser General] billysam:
No need to downgrade, I successfully installed and Rooted my device without downgrading at all, don't have to make it complicated. refer to this post here.
[Zenfone 2 Laser General] camseye:
You can root without downgrading but can not flash custom roms.
[Zenfone 2 Laser General] billysam:
I don't think so, get your facts correct before helping others out and go through everything, enough of confusions on XDA and new members suffer. According to this post by [MENTION=5075128]LuK1337[/MENTION] on post I see it is important to be on the latest firmware rather than downgrading to an older one.

[Zenfone 2 Laser General] TheOtherTiagoTiago:
Oh, great... So that is why it was crashing instead of unlocking the bootloader? Why have the mods allowed the post to stay up so long if it's a virus?

How do I remove the virus now?

Btw, I did find one that seems to work for the ZE550KL linked here (direct link to the file); it says it's for the ZE551KL but seems to have worked on my 550 with the firmware WW_user_21.40.1220.2192_20180109, TWRP installed without a hitch. The file size is 782 instead of 735 KB, but it's from the same site (dlcdnet.asus.com), so it is possible it is compromised in a similar manner if OP's indeed is.

Hello! I'm using ZE550KL (Marshmallow 6.0.1) and can't unlock the bootloader using the tool. It says "An unknown error occurs, which may be a network connection issue." I tried using both WIFI and mobile data but I get the same error message. I'm trying to install TWRP that's why I want to unlock the bootloader. Hope someone can help me. Thank you!

[Zenfone 2 Laser General] fstirparo:
Hi! I'm going through the same issue. Were you able to solve it and unlock the device?.

Thanks!
[Zenfone 2 Laser General] o_chiemi:
I actually managed to root my phone and install a custom ROM without unlocking the bootloader (or probably the bootloader was already unlocked? idk). I read somewhere that the official tool will not work since the phone is not supported/updated anymore by ASUS (or something like that).

I followed the instructions here, but skipping the bootloader unlock tool and just installing TWRP, custom ROM, Gapps, and root add-on.

But I'm not sure if what I did will work for others, please proceed with caution and don't forget to make backups!
[Zenfone 2 Laser General] wickedpygmy:
what a peculiar subtle difference. In my experience of BT smart / low energy, most manufacturers havent implemented any of the new features of 4.1 (e.g. channel-oriented connection), because they are optional, but have just re-certified their existing 4.0 functionality against the 4.1 spec... in other words, there may not be any difference other the test suite it was certified against.

but yes, clearly there are some differences between the handsets!
[Zenfone 2 Laser General] destilant:
I know offtopic, but there are different types of ZE550KL released, some (like mine) with 610, some (like yours) with 615

extract from my build.prop (/system partition):

ro.build.display.id=LRX22G.WW_user_1.15.40.639_20151029
ro.build.csc.version=WW_ZE550KL_1.15.40.639-20151029

ro.product.carrier=US-ASUS_Z00L-WW_Z00L
ro.product.device=ASUS_Z00L_63

msm8916 = Snapdragon 610
[Zenfone 2 Laser General] wickedpygmy:
Thats the 410 ;)
[Zenfone 2 Laser General] PushkaRR:
Yeah my ze550 has 410
[Zenfone 2 Laser General] wickedpygmy:

[Zenfone 2 Laser General] dexter20082001:
I don't want to confuse people even more, but I believe that the board names are deceptive as the 410 is a 4 core and only 32 bit but my ZE551KL has 8 cores and is 64 bit. The processor is detected as a 615 while the board is detected as an msm8916. i believe it was an oversight when the boards were made or done as a way to take the same board for all phones to ease in mass production.
[Zenfone 2 Laser General] rajlko:
Can not say anything but we have option to download from server.

wrong 410 is 4 core 64 bit

[Zenfone 2 Laser General] wulfe13:
i wonder if this will work on ZE500KL too.. what do you think guys?
[Zenfone 2 Laser General] AcmeWidgets:
Couple of questions please:

When applying bootloader unlock app does it reset settings on the phone? In-other-words; when I restart the phone will I have to reset any settings?

Other question: when upgrading firmware are we supposed to flash the kernel source code afterwards?

Thank You in Advance!
[Zenfone 2 Laser General] kmrnagireddy:
Any possibility to get back to locked boot loader and in warranty

Thanks all, after unlocking the bootloader.. Is there any way to lock bootloader.. like flashing firmware .. does flashing firmware stock rom will give locked phone and with warrenty..?
[Zenfone 2 Laser General] xyberz09:
No OTA updates for bootloader unlocked devices (probably)

I don't know for sure. We'll find out when the next OTA update is released, but when you choose to run the bootloader unlock utility, you are agreeing to this:

However, if you haven't modified the stock recovery or any of the stock files in any way (i.e. you only added new files, apps like SuperSU, etc. but didn't modify any existing system files) then you may be able to download OTA updates from ASUS' servers manually and apply them using the stock recovery (by placing them in the root of your SD Card and renaming the file to MOFD_SDUPDATE.zip). Since OTA updates are differential patch files, they probably won't work or will have unexpected results if you have modified system files (like the recovery) and it's tries to patch those files.

The download links to the OTA updates can be found (I think) by running this command:

cat /data/data/com.asus.dm/files/tree.xml (More info on that in this thread by [MENTION=1813976]shakalaca[/MENTION])

If you still can't find the OTA download links, then maybe you could set up Fiddler proxy on your computer and capture Android web traffic and find out how the OTA app queries ASUS' servers for OTA updates and download the updates manually (you may need to do this on a phone with a locked bootloader).
[Zenfone 2 Laser General] wickedpygmy:
no, we do not believe so, but no-one has tried.

no it does not reset the phone, everything will be the same, all data, apps and settings

you do not need to mess with any source code, just get the latest zip file from Asus website, put it on the root of the sd card and flash from recovery, or boot up the phone and it will prompt for the update

we currently have no way to re-lock the bootloader.
[Zenfone 2 Laser General] wickedpygmy:
There is no problem updating. I was able to update from v1.15.40.771 to v1.16.40.763 after unlocking, by manual update in recovery.
[Zenfone 2 Laser General] xyberz09:
Thanks for clearing that up. So manual update is possible but OTA updates are blocked? Bootloader unlocked devices will have to download the full stock firmware from ASUS' website and flash that through recovery, right?
[Zenfone 2 Laser General] wickedpygmy:
Actiually i dont know if OTA is blocked, just saying that manual is is still fine.
[Zenfone 2 Laser General] amol8356:
can someone post the link/Apk of bootloader unlocker tool for ZE550kl for snapdragon 410?

Edited: Got the links from 1st post.
[Zenfone 2 Laser General] rczrider:
Subscribed. Already unlocked the bootloader on my ZE551KL and wish I hadn't just so I could provide info to help with re-locking. Oh well.

Hopefully TWRP for the 551 is right around the corner.
[Zenfone 2 Laser General] codejam100:
Can we re-lock the bootloader if it was unlocked ?
[Zenfone 2 Laser General] wickedpygmy:
you can back up the locked bootloader before you start if its not too late
[Zenfone 2 Laser General] codejam100:
Oh no I missed the opportunity ! Can sone one help ? In case I need warranty repair
[Zenfone 2 Laser General] rczrider:
Ditto. Certainly would have done it had I known or thought about it, but no idea how to even back up the bootloader. Can someone explain (and perhaps the OP can put it in the first post) how to do it, so that we can get some locked bootloader images for restoration?
[Zenfone 2 Laser General] wickedpygmy:
I did add to the original post titokhans instructions for getting a dump of aboot partition, but im not totally clear whether that dump would be in a format suitable for flashing with fastboot. some research needed (or someone with experience)!
[Zenfone 2 Laser General] wickedpygmy:
regarding re-locking, I just flashed all the following in fastboot from the manual update package:

fastboot flash aboot emmc_appsboot_8939.mbn

fastboot flash sbl1 HD@firmware@8939@sbl1.mbn

fastboot flash rpm HD@firmware@8939@rpm.mbn

fastboot flash tz HD@firmware@8939@tz.mbn

bootloader is still unlocked. It seems like there is possibly a flag set somewhere in other memory which I cannot clear. I think I really should have done a full dump of all boot-related partitions before I started!
[Zenfone 2 Laser General] heywheelie:
I think the bootloader is like knox. Once triggered it can't be un-triggered.
[Zenfone 2 Laser General] wickedpygmy:
Perhaps, but we dont know. It would be good to compare a full dump before and after unlock
[Zenfone 2 Laser General] rczrider:
That's certainly possible. When I unlocked mine, I tried it in airplane mode. It wouldn't run without internet access. That could be because the unlock tool is universal for all variants and it needs to download something specific to the variant you're running it on...or it could be reporting to ASUS that you're unlocking your bootloader so that your warranty is voided forever and ever :p

And if that's the case, that sucks since locking it back up won't make a bit of difference if you have to make a warranty claim. Who knows, though. I hope I don't ever need to make a claim, but if I do, I'd rather do it with a re-locked bootloader so I could argue with ASUS if need be.
[Zenfone 2 Laser General] wickedpygmy:
You have made a great point. It is almost certain that the app phoned home and ASUS have recorded the serial number has voided warranty.
[Zenfone 2 Laser General] rczrider:
It would be the smart thing to do on their end, so I believe. I'd still be willing to argue the point (assuming we could re-lock it) and say I never did it.

All-in-all, though, I'm not going to sweat it too much. I wanted root badly enough to do it, though I'd certainly have opted to keep it locked if I could have had root and TWRP at the time without unlocking.
[Zenfone 2 Laser General] heywheelie:
yes I tend to agree with you. Makes sense. Sucks tho. Knox is used by enterprise use for security, this is just a backdoor to try and save a few dollars on warranty.
