Hello guys.
I'm trying to unlock the bootloader of my ZE550KL several days ago. All my attempts were a huge failure.
I did the downgrade version, used the unlock utility of ZE600KL/ZE601KL/ZE551KL, downloaded WinDroid Toolkit 3.1 @Rapscallion16 and the application does not detect my phone. Anyway ... NOTHING WORKED.
I am looking to install TWRP and CM13, but without unlocking is impossible.
I see the Zenfone 2 Laser forum users posting various ROMs for this model from Asus and is my question, as did the unlock of this ZE550KL model? It's a real mystery! I am extremely angry about it.
How to proceed? Can someone help me? Thank you very much!
NOTE: I'm sorry for the English text by Google Translator
First answer me the following question
1/ what is your software version?
2/ is your phone rooted?
Do you happen to have the Snapdragon 615 with 3 GB of RAM variant of the ZenFone 2 Laser?
I havent tried using the windroid kit and downgrading but i tried to use the asus unlock tool, and i think it didnt work because i know when the unlocker reboots your device, the boot screen should be different(as said by my friend, using a ze551ml model) but my phone hasn't changed its boot screen. Here is the photo of software ver. and i am not rooted, because i know you can't root if you can't even unlock the bootloader(correct me if i am wrong)

Well, i got mine unlocked and rooted as of now, and i got twrp and cm13 working, so here's the story:
I downloaded the unlock tool here:
https://drive.google.com/file/d/0BzRHX4h-XXIxcHk5Q2xXV2RCWGM/view
Once i downloaded that, i uninstalled the old asus unlocker tool i had and installed the one i downloaded from the link.
After that, the unlocker tool did its thing, rebooting my phone after i accepted everything.
I installed adb on my computer and did the commands to confirm if i had my bootloader unlocked. Well, it turns out, my bootloader is unlocked! Yey, it worked with 1.17 firmware!
After that i installed SuperSU first and twrp, and get cm13.

when you got it unlocked ? ( tell me the date pls)
Are you on 1.17.40.1234 or .1531
Can you provide more info about you device?
1. Link to the unlock app that you used ?
2. Did you root before trying unlock app?
3. Were you able to recieve ota updates BEFORE unlocking?
4. Did you ever flashed ZE600KL's official firmware?
I am asking this because-
After various failed attempts with unlocker, I flashed ze600kl's 1.16 firmware after editing my build.prop to make it look like ze600kl. And then used unlock app. At second attempt i got "The device is unlocked" but fastboot says its locked. Also my device boots over the normal black background. I then flashed ze550kl's 1.17.40.1234 and tried unlock app. Again it says "The device is unlocked" without even restarting the device. Seems there is some flag set up in my phone which tells the unlocker that the device is unlocked. But until fastboot shows device unlocked true my phone will remain locked. Now i can't try the patched unlock app, since it too says the device is unlocked.
Use the unlock tool from ZE600KL. It worked fr me. I was on the same software version.

My device? Mine is the 3gb and SD 615 variant of the laser. I bought it from the Philippines, since it was the better option for me(ZE551ML there is sold out/phased out). I unlocked the device at May 24, 2016. The firmware i had when i was unlocking was posted on my first post here (it's a pic). When i unlocked my device, the boot is still the same, unlike ZE551ML's which makes the boot screen white.
1. I posted the link to the unlock app i used on my story post.
2. I didn't root before unlocking. I rooted after i successfully unlocked the bootloader.
3. When i bought my device and connected it to my wifi at home, it immediately gave me a notification of an update.
4. I never flashed ZE600KL's firmware. But i tried to use the unlock app of ZE600KL (because they said to use the unlock app of ZE600KL for the ones who have 1.16 and up firmware)
I think why you can't unlock it is because of build.prop config you did. Well, i don't really know, but i never did anything like a build.prop config on mine just to unlock the bootloader.

Have You tried flashing anything? I also happen to have ZE550KL Snapdragon 410 with 2gb RAM model, having 1.17.40.1531_20160428 build number and i haveNOT rooted it. I tried the unlock utility. It failed many times (Asks for PIN then restarts but nothing happens) . But eventually it said bootloader is Unlocked (after like 20-30 attempts) even though the start sreen was black and not the inverted one as mentioned in the forums . I was happy but that happiness was shortlived. I then tried to go in fastboot and flash twrp, it happened but i was unable to boot into recovery, for some reason it just boots into the OS, later when i just wrote the command
"fastboot boot twrp.img "
I was greeted with an error saying
downloading 'boot.img'...
OKAY [ 0.944s]
booting...
FAILED (remote: unlock device to use this command)
finished. total time: 0.953s
I don't think I should receive that error if my device is unlocked.
I wish to use twrp to take a backup of my NON ROOTED firmware. and then flash the CM 13.
Any help would be greatly appreciated

Your bootloader is still LOCKED, shocking isn't it? It happened to me as well. The unlock app gives "the device is unlocked" message but when I checked in fastboot using
Code:
fastboot oem device-info
the boot loader unlock status was "false" which means loader is still locked. I wish if someone can find an unofficial method for unlocking boot loader on ze550kl
i got this same problem with ZD551KL , no solution until now.
Amazing reply from ASUS tech support

I wrote to Asus Tech support regarding the incident . I told them that I tried unlocking with your Unlock Tool which gives "the device is unlocked" message but when I checked in fastboot using "fastboot oem device-info " the boot loader unlock status was "false" which means loader is still locked.
To which they replied
"As your query, ASUS does not provide further unlock bootloader tool for users.
If you want to unlock, please refer some more instruction on internet and do at your own risks.
We are so sorry for this inconvenience"
I don't know which Internet was he referring to but I could find any working method to unlock the bootloader.

LOL. Two days back, they launched unlock tool for ZE500KL. I dont unerstand why they are ignoring the most popular variant i.e. ZE550KL.
I am currently working on a possible solution to this issue. I will post a separate thread if successful. I will laugh at the zentalk forums once I unlock BL

downgrade to 1.16 lollipop unroot my phone run the tool which u said accepting all the option prossec run for some time and gives the popup fail to unlock
I'm new to MiUi and request for some help.I have a Redmi Pro which came preloaded with a ROM from a vendor. I managed to flash Chinese Developer ROM 7.6.10 on the phone. I want to use miui.eu ROMs as there is no other global ROM for Redmi PRO. I have requested and been granted permission for unlocking my device however the unlock tool doest detect my phone in fastboot mode. USB debugging is enabled. the phone appears as 'connected' when I use version 1 of the unlock program but prompts me to use a newer version when i click on un lock. I can access the device and it's contents in MTP mode. attached is a screenshot of the Unlock tool page. I've removed and reinstalled drivers for the device but it still appears as not connected. I checked in ADB, the device does appear in fastboot mode.
Good evening everybody, I've been away from android modding for few years and probably got rusty.
Today I've purchased the Asus Zenfone Max M1 (X00PD).
I've completed the installation of the adb-setup (1.3 version), let my pc (Windows 10 64 bit) recognize the device both on and in fastboot mode.
I've also enabled debug mode and installed the specific drivers, as many guides indicate.
When I connect my smartphone in fastboot mode and try to unlock the bootloader by clicking on the "unlock.cmd" a windows appear for a brief moment and then disappear, can't really know if if was a success or no.
When i try to flash TWRP 3.3.1-X00P i get the "partition flashing is not allowed", after searching it seems that my bootloader is still locked.
The fastboot oem unlock gives "oem unlock is not unlocked".
Am I missing something? And if i figure how to finally unlock the bootloader, is the X00P recovery good for my X00PD device? Can't find a proper X00PD recovery apperently.
Thanks in advance for any answer.
UPDATE: apperently the guide I was following to unlock the bootloader was for the PRO version, google was very sneaky with me.
I installed an APK directly on my smartphone, executed it and my bootloader was unlocked. flashing the twrp with the usual procedure was a piece of cake

Yes, it was my mistake. Have to say in my defense that i've searched for the regular M1 version on google and it's shown me PRO related results, the PRO word was mentioned once in a very long title that my mind skipped on it.
Hope somebody with the same issue can find this thread in the future and figure out what went wrong. Thanks again for the assistence!

Hi.
I see that You can find the unlocking tool on a not-existent page, that's why I'll ask: Do You know address where i can find the unlocking tool for the ZB570TL model X018D version? My wersion of this app (9.1.0.3_18.06.21_fulldpi_signed) does not unlocking the bootloader. Fastboot command too. I will be grateful for You help

Dude nooo...
You could have used the unofficial method. Well your warranty is gone now and you might have lesser chances of relocking your bootloader but i guess you already knew it was a risk since you wanted to unlock the bootloader.

There is no unofficial way for Max 1
Max 1 Pro has it's own way but it's not working on the M1?!
como faz twrp no X00PD?
UPDATE:
I successfully unlocked the bootloader, flashed twrp, rooted, updated kernel and roms, tweaking gpu cpu for performance in pubg etc, greenify, flashify, power nap everything.
xposed framework take you in bootloop for this device.
now i am on kernel mk2000, superv20 rom, h91810u, 7 nougat.
if in future anyone feels any problem i am always here.
remember: linus is your friend for this device, and windows 10 suck.
and
sudo $(which fastboot) did miracles for me....
old post:
Hello everyone.
i am new here and i am sorry in advance if i did something wrong. i will come directly to the point.
model number: LG V20 T-MOBILE VERSION, H91820H, NON USA, Currently on oreo android 8.
we are not talking about any kind of roms kernels roots or anything here. just a simple question. " can this model's boot loader be unlocked ? like ever ? or not "
cause i have tried everything, when i say everything i mean everything. followed several posts on internet videos on you tube posts on XDA, tried using multiple PCs, multiple data cables, multiple drivers but for some reason i don't know what, this model's boot loader cannot be unlocked.
THE ERROR:
<WAITING FOR DEVICE> till eternity.
what i have done till now ?
1. lg drivers installed.
2. adb drivers installed with adb fastboot files.
3. updating legacy android adb interface driver, done.
4. went in to boot loader then connected the data cable and updated driver, done.
5. usb debugging oem unlock options activated, done.
6. restarted pc multiple times to update drivers, done.
we all know all it takes is 3 easy commands to unlock bootlaoder
adb reboot bootloader
fastboot oem unlock
fastboot reboot
but in my case i always stuck at 2nd command. waiting for device is shown and nothing happens.
then i ran command, adb devices>> it shows
List of devices attached
adb server is out of date. killing...
* daemon started successfully *
LGH9182bfc6bdc device
next i put the command, fastboot devices and nothing is shown i just go to the next line... c:\adb>
so this is for sure that my device is not connected to the fastboot.
now my only question is, can this device bootloader unlock or not ? so that i stop pushing my limits.
any help will be appreciated.
regards.

To be very precise after following the first step while unlocking the bootloader in the second step when we type fast boot devices it should show some hexadecimal numbers and it should confirm us that our device is in the fastboot mode but in my case whenever I type this command nothing happens that means my device is not recognised to go in the bootloader this is the main problem there is no point in following any of the posts if you cannot complete the very first stage of unlocking your bootloader if you can figure out what exactly is the problem I will be thankful to you because I have followed every step possible I've updated every ADB drivers LG drivers but nothing is helping out as even before starting the procedure of unlocking the bootloader my device is not going in the fast boot also I noticed one thing when I try to go inside the bootloader screen before that in my device manager it is shown as composit device but after that I think it gets disconnected fastboot oem unlock cannot work as it gives a message of waiting for the device after going are using the command ADB reboot bootloader so my problem is the command fastboot oem unlock is pretty useless as it waits for the device and it's stuck there forever please help me out if you can I will be thankful to you regards

Did you downgrade to software version H91810P? Because that should be the first thing you have to do to get everything else to work afterwards.

Thanks for the reply.
Can you please clear me one thing. To downgrade from h91820h to h91810p you need to unlock bootloader if i am not wrong. And in that case we will be back to square 1.
Its not about installing custom rom kernel recovery root or anything. Its only about unlocking the bootloader which i cannot do.
I hope you understand my pain.
I just want to unlock my bootloader thats it.
It used only 3 commands.
1. Adb devices - shows my device.
2. Fastboot devices - no fastboot device found.
This is the problem. When you cannot find any fastboot device even updating driver by going inside the bootloader the entire mission gets failed.
I cant find any solution for this. I dont know for what reason my device cannot be listed in fastboot mode.

fastboot doesn't work when the phone is booted up
adb reboot bootloader
followed by fastboot devices
Note: flashing the 10p kdz does not require the bootloader be unlocked
it requires you have patched LGUP
Example:
D:\fastboot>adb devices
List of devices attached
LGUS99740047103 device
D:\fastboot>adb reboot bootloader
D:\fastboot>fastboot oem device-id

As clsA said, flashing firmware does not require an unlocked bootloader.
Look at parts 1 and 2 of the other step by step guide here:

Thanks for the solution. May be this is it. All the time i have been doing it wrong.
Solution : flashing the 10p kdz does not require the bootloader be unlocked
it requires you have patched LGUP.
I will downgrade from 20h to 10p now and will give you feedback on this soon. Thanks a ton for showing a noob like me the right direction to work.

lgup error 0x2bc invalid command response code = 0x80000202 at 4 percent while flashing.

used the provided kdz file flashing as an upgrade.
ok so the new problem is... may be i was trying to flash h91810p naugaut on to a oreo h91820h
and if i am not wrong at this stage i messed up pretty bad my phone is stuck in donwload mode wont boot up and i need to flash back 20h again to get out of this mess. can anyone hlp me ....
i just wanna know h91810p downgrading from 91820h is possible or not ? cause one is naugaut and one is oreo.
UPDATE:
i was flashing wrong h91810p thats why it was showing error. on another website i got the file compatible to my phone t mobile version and flash was successful.
now i am on h91810p software version andriod 7.
problem UPDATE:
i still cant unlock bootloader. same problem as before downgrading from h91820h.
adb devices shows device.
adb reboot bootloader
fastboot devices gives no result.

D:\fastboot>adb devices
List of devices attached
LGUS99740047103 device
D:\fastboot>adb reboot bootloader
D:\fastboot>fastboot oem device-id
after this it only says waitng for device"
now i am on h91810p as i was instructed. can you please help.
its all happening the same way it was happening when was on h91820h.
fastboot devices cannot be found.
once it reboots in bootloader then it should detect a fastboot device but it doesnot and adb is also lost there.
kindly help.
NEW UPDATE:
my lg v20 now on software h91810p is actually a T MOBILE version. and when i researched more about it i found out T MOBILE deliberately locks the boot loader of many devices and its unlockable.
possible work around can be if the software version installed on your phone can some how be an international version of your ROM, then only you can unlock the bootloader else none of your commands will work. now i am trying to flash this phone using an international ROM version if i succeed i will update. but according to my knowledge flashing other roms other than t mobile ones will definitely give errors in LGUP.

Do not flash another model's firmware onto the H918! Doing so will permanently brick your phone. The H918 in particular is incompatible with all other variants' software. Also, flashing H918 firmware onto any other model will also brick that phone.

i have seen people doing on t mobile on youtube videos i dont know how they are doing it.

Did you make the Linux USB boot stick
Are you following the guide at all?
PART 3: CREATING A BOOTABLE LINUX USB USING FWUL
DOWNLOAD FWUL_v2.7_x86_64_15GB.zip FROM THE LINK BELOW AND EXTRACT THE IMAGE FILE SOMEWHERE IN YOUR PC.
https://androidfilehost.com/?w=files&flid=214529
DOWNLOAD RUFUS FROM BELOW AND INSTALL
https://rufus.akeo.ie/
INSERT A PEN DRIVE IN YOUR PC AND RUN RUFUS.
INSIDE RUFUS SELECT THE IMAGE FILE AND SELECT START (AFTER SELECTING START SELECT DD MODE IN THE DIALOGUE BOX) TO CREATE A BOOTABLE PEN DRIVE (WARNING: THIS WOULD FORMAT YOUR PEN DRIVE)
NOW YOU SHOULD BOOT YOUR PC FROM THE BOOTABLE USB STICK WHICH YOU HAVE JUST CREATED
THIS WOULD MAKE YOUR PC RUN LINUX OS
TYPE PASSWORD AS linux AND ENTER

Why does adb show your device as a 997 which is the Sprint variant
Sent from my LG-H910 using XDA Labs
Hi
I recently tried loading Lineage OS on my Asus Zenfone 3 (ZE520KL). Didnt get far though. Got stuck unlocking my bootloader via adb. As a result phone is no longer detected in adb. The phone is getting stuck at ASUS logo and I cant boot to recovery either. It does get detected by fastboot but nothing more. I have tried :-
(1) loading various ROMs downloaded from Asus website onto the microsd card
(2) using asus flashtool (various versions). The latest one says battery is -1% while the earlier version returns various errors including "frp request server log access is denied" and "failed to write partition"
(3) I have (seemingly) been successful at pushing recovery and boot images via fastboot but the phone still wouldn't go past the Asus logo when rebooted
Read a lot of threads but not much seems to be working.
Help please !
Thanks
For what its worth, I ran the 'fastboot getvar all' command and this is what I got. Seems to be a truncated run.
Hello,
I have the same problem as you, I only have access to fastboot mode and can't access to recovery mode. Have you find a solution ?
Thanks.
How did u solve the problem?
UnBrick (EDL) - ZE552KL Libra_QFIL_8953_01020_20170714_Aboot.7z
There is guide too, You can check in ROMDevelopers
