can i know what bugs you encountered ?

I m planning to go for cm.

.

I have few doubts.

1) Where can I get stock recovery for ze550kl ? I am on 1.17.40.1234 update.

2) is this root method working on latest update 1.17.40.1234 ?

3) Is there any way to take backup of stock recovery after unlocking bootloader ?

.

As far as I know, stock recovery is important for going back to 100% stock, so...

I am currently on pure stock.
[Zenfone 2 Laser General] RohanAJoshi:
edit :

after playing sometime, I found my answers.

this root method working on latest 1.7.40.1234 update, so i used flashify to backup stock recovery.

Ze551kl

Yeah I just got the ze551kl too and I love the phone. I will probably root it eventually. I bought the phone off of Amazon after doing my research. One question. The phone has the Qualcomm 8939 615 snapdragon whatever lol clocked at 1.5 GHz on the 4 cores and 1 for the other four. Anyways, from what I have read, the processor is capable of 1.7 GHz. Just wonder why it is clocked down to 1.5? Is this to save battery or lessen heat maybe? Is there a way to get the full 1.7 out of it without rooting and kernel and all that? Yeah I know it probably will not make much of a difference in the real world. Guess that was more than one question. Lol. Would like to know what is capable with Roms and rooting? Are there Roms available that keep all functionality and are stable? Would like to get rid of the zenui and go to something more stock Android.

I have applied this root, but am having a lot of issues to update from 1.17.40.1234 to 1.17.40.1531.

I have a ZE551KL model.

I tried following this post's instructions: http://xdaforums.com/showpost.php?p=65612824&postcount=162

Here's what I did:

- Used supersu to fully unroot.

- Applied stock recovery (from link in instructions post).

- Copied update firmware to root of sdcard.

- Booted into stock recovery, attempted to apply update from sdcard. Got the following error:

"footer is wrong

signature verification failed"

- Tried re-downloading the firmware. Did a hash comparison, both are identical, doesn't seem to be corrupt (though I don't have an official hash to compare to).

- Tried applying same way again. Same error.

- Tried applying through adb sideload, but I get "can't read" errors. (Yes, I am typing the file name correctly, including extension. Yes, I'm running it as administrator. Yes, device appears on "adb devices". No idea why this doesn't work).

- Tried applying TWRP again and flashing from it. It says file is corrupt.

I really don't think the files are corrupt. I downloaded it a third time and verified it's exactly the same as the previous ones.

What could be causing this issue?

Note: my device has encryption on, but I also tried removing the password. Didn't help.

Note2: the recovery is from a version about 4-5 updates old. Could this be the issue? I don't have a newer recovery or know how to get it.

Note3: firmware files taken from https://www.asus.com/us/Phone/ZenFone-2-Laser-ZE551KL/HelpDesk_Download/ (yes, mine is WW)

Edit: for testing purposes, I tried flashing the same version I'm on (1.17.40.1234) and it worked correctly.

This is really weird. It's just 1531 that won't work.
[Zenfone 2 Laser General] tazepam:
What is your bootloader state ? Maybe you should just relock it (or unlock) it ? ( just a suggestion ) :)
[Zenfone 2 Laser General] danannn:
It's unlocked via official tool. I'm not aware of any method to relock it
[Zenfone 2 Laser General] a8a999:
It works!

It works on ZE551KL. Thanks!:)
[Zenfone 2 Laser General] shadiajenika:
will this work on the marshmallow update? anyone who tried it? :confused:
[Zenfone 2 Laser General] subzero_sv:
Thank you for the detailed explanation :good:

I can confirm it working on ze551kl firmware 1.17.40.1531_20160427 :cool:
[Zenfone 2 Laser General] nujaxx:
Everytime I try this it says waiting for any device. It's not picking up my phone. Which is weird because all the drivers are installed. I'm lost.

im pretty sure, the asus unlock tool is garbage for starters.
[Zenfone 2 Laser General] caldent:
If you have unlocked your device earlier you don't need to unlock again. The unlocked bootloader ones are those which don't get any OTA update.

---------- Post added at 12:01 PM ---------- Previous post was at 11:59 AM ----------

Moreover before the actual Marshmellow update there is a patch update issued by Asus. You have to install that before you can update to Android M

---------- Post added at 12:04 PM ---------- Previous post was at 12:01 PM ----------

You just have to unroot the device,flash the original bootloader (if you did install TWRP ) and put the update in internal memory.

---------- Post added at 12:08 PM ---------- Previous post was at 12:04 PM ----------

And yes Let the phone detect the update from home screen. Try restarting few times. Adb sideload didn't work for me too and initially the bootloder also failed to read internal sd.
[Zenfone 2 Laser General] chris751:
I flashed it twice but it didn't work. I have a ZE550KL, and I think that I connected the device in the right way because when I wrote "reboot" on the window, my phone rebooted with no problems. I can also say that I connected it in the right way because when I checked the bootloader status, it told me it was unlocked, so...
[Zenfone 2 Laser General] long2ski:
I want to root my ze 551kl and successfully unlocked the bootloader with the official app. My question is if I root now do the updates lose root anyway or is root maintained through updates ( as long as I don't change recovery to TWRP)? Has anyone on the 550 with Marshmallow and root kept root after updating?
[Zenfone 2 Laser General] andrehsu:
You will have to reroot after each update
[Zenfone 2 Laser General] long2ski:
Thanks form the quick reply. One more question. Does the same image root all firmware updates? It looks like it has been successful for everyone thru the 1.17 updates. I am in the 1.17.40.1531 firmware.
[Zenfone 2 Laser General] andrehsu:
I would recommend that you use twrp and flash the supersu zip
[Zenfone 2 Laser General] long2ski:
Has anyone tried this on Marshmallow? I have the ze551kl and have always rooted my phones but after reading lots of posts about being unable to unroot and get stock recovery back for updates , I am a little reluctant to try on my only phone.

The other question is will it work to use adb and reboot into twrp.img(but not flash it) and not the boot image posted, then install supersu to keep stock recovery? I have UNlocked bootloader. I know I can flash twrp but want to keep stock recovery.
[Zenfone 2 Laser General] EchoeSD:
I don't understand something. You say that we lost the updates notifications via OTA because we made the unlock bootloader?

What if i rooted my phone only with the boot_200007.img file in this post? only updating to V1.17.40.1234, then rooting with the file and ADB, nothing more. That's not TWRP right?

The root work good, but i want to update to marshmallow.

And my Asus zenfone 2 ze551kl is V1.17.40.1234

What do i have to do to upgrade my zenfone to mashmallow ?

Please someone help me :(

There's someone still there that can help me :(?
[Zenfone 2 Laser General] long2ski:
I'm not sure what you are asking but in my own experience, I tried to root on my ze551kl on stock marshmallow with this modified image and it was a disaster. My advice , for what it's worth, I would update to marshmallow (even if your bootloader is unlocked, you can still update to marshmallow by downloading the update from Asus site and put it in internal memory). You lose root. If you really want root, flash twrp, back up, then flash supersu. Don't bother with this boot image posted.
[Zenfone 2 Laser General] EchoeSD:
Thank you so much!!

At the beginning i have had problems because i didn't update to the last version of lollipop for the ze551kl and the updating to marshmallow has failed. But then , after updating to the last version , i update to marshmallow and everything was ok.

Now, how can i root my phone? can you bring me the details to root ?
[Zenfone 2 Laser General] danarputra:
Is firmware 21.40.1220.1708 is latest firmware update from Asus web?
[Zenfone 2 Laser General] EchoeSD:
To root the Ze551kl with Marshmallow you have to:

1. flash TWRP recovery on your device

2. flash Supersu

Checked by me !! :D it works

[Zenfone 2 Laser General] caldent:
If you have Android M then try systemless root from SuperSu
[Zenfone 2 Laser General] sichokie:
Hi there, thanks for the suggestion.

I just found some working method which you can read here in my post.

Hope someone with the same model as I am will find this helpful

Why you cant use the official unlocker? Did you try the official unlocker from asus web?

I have ZE550KL (Z00L/Z00LD) and want to root my device and try custom ROMs. My firmware is WW_21.40.1220.2087_20170331. Will the root method work for this firmware? Any help will be appreciated. Thanks!
[Zenfone 2 Laser General] Gustapo:
I tried installing minimal adb and fastboot on my laptop and thanks to my antivirus (McAfee) the exe is deleted every time I try to run it. I've tried disabling McAfee but no luck. It's my office laptop and I have no other so stuck on how to proceed. Anybody faced similar issue? :(
[Zenfone 2 Laser General] aadi50:
Just add the folder to scan exclusion list. I dont use mcafee but every antivirus has option to add paths/files to scan exclusion list. Browse the file/folder to excluded from scan and add it.

Just check for the option in settings or google how to add files to exclusion list in mcafee.
[Zenfone 2 Laser General] Gustapo:
Thanks! Unfortunately the "McAfee virus scan console", which contains options for exclusion, is not available to me in program files etc. I managed to get adb (1.0.31) from internet and able to execute "adb devices" command and am able to see my phone. Is this adb version sufficient for rooting or I need to have latest?
[Zenfone 2 Laser General] aadi50:
I think its sufficient if its recongnising your device. I dont even know my version of adb. I just use and it works. It never mattered.
[Zenfone 2 Laser General] Gustapo:
So I got the device to recognise and reboot into fastboot mode. Now when I run "fastboot boot boot.img" I get the following error.

downloading 'boot.img'...

OKAY [ 1.132s]

booting...

FAILED (remote: unlock device to use this command)

finished. total time: 1.137s

So I downloaded the bootloader unlock tool and it gives an error (An unknown error occurs, which may be a network connection... blah blah) when unlocking and I'm not sure how to unlock bootloader now.
[Zenfone 2 Laser General] Gustapo:
Never mind. Used "fastboot flash recovery <img file name>" and it works. Have TWRP and root now.... Wohoo!! :)
[Zenfone 2 Laser General] FuzzyFone:
Hello. Good Sunday to you all. I just did this on my ze551kl and it's just sitting at the Asus logo with the spinning circle.

I used the unlocking bootloader from asus site, went to fastboot with phone hooked up to computer, ran the fastboot boot boot_20007.img and it said everything went ok, it rebooted and is just stuck here. :/
[Zenfone 2 Laser General] seanb2112:
Me too...

I got the same thing. Does anyone know a way to back out this change?
[Zenfone 2 Laser General] FuzzyFone:
Seems to be little help around for this phone .

I'll try to get back to you in a little bit. I thought I posted that I got it fixed. Just so much on my tiny little mind lately.

My ZE551KL got stuck in logo

Greetings to all members of XDADevelopers!

I write to you all because i need help with my phone. After applying the rooting method showed here, the phone got stuck in the boot logo (the second screen with the rolling circles). Here is what i did:

-Unlocked the bootloader with the asus apk. No problem.

-After installing all the drivers, executed adb as administrator, put the phone in fastboot mode and executed "fastboot boot boot_200007.img". The cmd returned the procces was executed ok, then the phone rebooted.

-After rebooting, the phone does not boot, the circles in screen keep rolling in the second screen.

My phone is an Asus Zenfone Laser 2 (ZE551KL) with Android 6.0.1.

Any help would be appreciated.

Thanks in advance.

Is there any way to receive OTA Updates after unlocking the bootloader?
[Zenfone 2 Laser General] yoelnico:
The only way to root asus ze551kl with MM is to flash twrp and after flash supersu.zip right?

yes, exactly.

[Zenfone 2 Laser General] pedrazadixon:
The best way for me is downgrading to a stock recovery and then flash a official firmware.

La forma mas fácil es haciendo downgrade de stock recovery y luego instalando el fiirmware oficial.

[Zenfone 2 Laser General] billysam:
Working Root and boot loader unlock for the latest 2017 august update.

Okay, for those who are late to the party and first time on a Asus device.

I was on the latest stock 2179 build that came on 20170803. using a Ze550KL Z00L.

**Unlocking Bootloader**

Enabled the Developer mode

Allowed USB debugging.

Setting -> Security -> checked allow unknown sources

I got the file from this post

Extacted the apk, copied to the device storage, installed it.

followed the on screen messages. and device reboots and back to the system. (Needs working INTERNET connection to work)

- Grabbed the latest twrp recovery from here

- Now, if you all have the adb and fastboot set up already. if not please download them from here

- Copy the twrp x.x.x.x recovery.img (rename the file as recovery.img for ease) in the same folder and Press ALT+SHIFT+ Right click, open command prompt here.

- Type " adb reboot bootloader "

- You can check the bootloader status here. by typing " fastboot oem device-info "

- Now type " fastboot boot recovery.img " ( this will not flash the twrp recovery to the device. I am not using it since I just needed access to the root on stock ROM. but if you want to use custom ROM and need the twrp recovery then type " fastboot flash recovery recovery.img " )

- Wait and let the device boot into the twrp recovery, so the first thing in recovery should always be to backup all the partitions. ALWAYS DO IT, MAKE IT A HABIT, cause I had zero Hard Bricks but thousands of soft bricks and bootloops, you will always need them if you're going to change things inside the system.

- Now for root I used Magisk from here (I used Magisk-v14.5-20171106-074848.zip but I am sure we can use latest as well.)

- download and place the zip in the sdcard.

- flash from the twrp recovery.

- reboot back to the system.

- I didn't find the Magisk Manager app installed in my device so I looked into the zip archive and extracted and installed the Magisk Manager app from there and I have it working.

Now I have a working root, an unlocked boot loader and a stock recovery. Cheers.

Note:- For Custom ROMs that are Marshmallow and above, You don't have to be on lollipop build, it's a must to be on the official stock M build first as it needs the latest boot-loader to work. DO NOT downgrade to Lollipop for any reason. you can refer to this post to check.

There are plenty of posts on the Internet suggesting for it, but they are outdated and doesn't apply for now.
[Zenfone 2 Laser General] miklast:
found my old ZE551KL, and decided to root it. Got to "fastboot boot recovery.img (i renamed to twrp.img instead) and got this:

downloading 'boot.img'...
FAILED (data transfer failure (Unknown error))
finished. total time: 5.004s

I know the bootloader did unlock:

(bootloader) Device unlocked: true
(bootloader) Charger screen enabled: false
(bootloader) Display panel:
(bootloader) Adb Enable: 0
OKAY [ 0.005s]

so im not sure what the issue is. Used the same downloads as you, running Marshmallow version 21.40.1220.1794_20160722060020715_201602190037.

Edit: Got past by updating to the latest version as of 4/10/18, changing cords and changing to a USB 2.0 port. IDK which fixed it, but its working now.

boot.img contained in update .zip release by asus work for apply new official updates?
[Zenfone 2 Laser General] rajlko:
you may extract from latest downloaded update zip.
[Zenfone 2 Laser General] rczrider:
I can offer another confirmation that this works for the ZE551KL on firmware version 1.16.40.763 (Lollipop 5.0.2). It's not hard, but if you're new to this, here's a little more step-by-step direction:

1.) Ensure you on the 1.16.40.763 firmware (as of right now, it's all that we know works). You can check by going to your phone's settings, scroll to the bottom and click "About" and then scroll down to "Software information". If you're not on the 763 firmware, scroll up to "System update" and download it.

2.) Download bootloader unlock .apk from ASUS to your phone and run (this will void your warranty, whether you root or not!). Your phone will reboot.

3.) Download ADB (I recommend Minimal ADB and Fastboot: http://xdaforums.com/showthread.php?t=2317790) and install.

4.) Download .img from the OP and move or copy to ADB installation folder.

5.) While phone is still on, plug into PC. If the "Allow USB debugging?" box pops up, check "Always allow from this computer" and hit "OK".

6.) Go to ADB installation folder, hold "Shift" and right-click, and select "Open command window here".

7.) Type the following commands. Your phone will reboot after the first and you should see "Fastboot Mode !!!". It will reboot normally on its own after the second command.

adb reboot bootloader
fastboot boot boot_200007.img

That should be it!
[Zenfone 2 Laser General] capeorigins:
