yes it's a firmware to downgrade from Marshmallow to Lollipop not a new Marshmallow firmware

just read the description :

ASUS ZenFone2 (ZE551ML) software Image: V52.20.40.196 for WW SKU only*

This is downgrade firmware from Andriod M to Andriod L .

Please ensure backup data before downgrade.

Downgrade to V52.20.40.196 (Andriod L)
[ZenFone 2 General] PepNYC:
Ok Thank you. Just so I know I'm doing it correctly I'm assuming I'm going to have to unlock the bootloader again. Tell me if these steps are correct and if I left anything out.

Step 1: Run "Unlock.bat". At the white ASUS logo with the white background force Shutdown by pressing power button for 10 seconds. Then start it into bootloader mode.

Step 2: Install stock recovery from fastboot mode. command " fastboot flash recovery recovery.img " (The recovery img is the one in the root of the zip file I extracted. See attachment.)

Step 3: After successfull execution of command go to recovery mode by pressing down button on bootloader mode and select recovery mode and stock recovery should come up.

Step 4: Go back to bootloader mode and run "Restore.bat".

I won't have to reflash the root zip files correct?

Really wish there was an untethered method to keep TWRP but I'd rather have some type of recovery method than none if I'm away from my PC.
[ZenFone 2 General] XeidiDent:
Yes, that should work. But I didn't need to unlock the Bootloader again to flash the stock recovery.

If everything works, you shouldn't need to reflash the root files.

Also, keep in mind that, if something goes wrong, I have nothing to do with it. Do it at your own risk.
[ZenFone 2 General] PepNYC:
That was way too easy. Worked like a charm. Thank you very much! :good::good::good:

Now if someone could find a way to get rid of that annoying warning on boot up. :)
[ZenFone 2 General] PepNYC:
I just went through the same issue. Doesn't work.

I've tried to flash TWRP with an unlocked bootloader. Every time I want to boot to TWRP I have to do it from my pc (tethered) with fastboot otherwise it will just boot back to the bootloader menu even after I choose recovery mode.. I just reflashed the stock recovery.img as XeidiDent showed me.

I'd really like to have TWRP and all it's features but what's the sense if it doesn't work when you're not at your PC and you need it? At least now I can get in to stock recovery if I ever need it and I'm away from my computer.

If you want to flash back to stock recovery read back in the thread.
[ZenFone 2 General] sd26:
I can confirm this works. I just updated to WW-4.21.40.144. Of course not rooted and no warning message. Thanks Kapil.

Ok

And ok for root also

Maybe the only difference between firmware.. 4.21.40.134 and 4.21.40.144 is the add of Brazil language :):D

Unrooted Automatically

I have rooted my as u r instructed, after that I've checked using root checker it shows ur phone is rooted, one day later i opened Xposed Installer app it shows "Xposed Framework is not installed" again i checked root checker and it shows ur phone is not rooted, i need a solution, what could happened to my phone, what should i do next.
[ZenFone 2 General] shazish:
For me all the steps work until running restore.bat

When trying to restore, I get 4 "permission failed" messages. I'm still able to boot afterwards but it's clear something's not working.
[ZenFone 2 General] Samurai Cop:
I tried unrooting by flashing a the stock zip, and used the twrp from this thread. It installed successfully, but I hit reboot and now it just boots to a black screen. I think I was supposed to use the option of rebooting to bootloader, which I didn't do. While plugged into the computer/AC adapter, it would vibrate every couple of minutes. Other than that, nothing. No light to indicate it's being charged either. So I think I bricked the phone. What to do?
[ZenFone 2 General] Grid4:
OP should have added unrooting steps in 1st post itself so that it makes a full guide., otherwise, good work.

[ZenFone 2 General] chowsen:

[ZenFone 2 General] thadoukuki:
Yes, I agree that it rooted the phone and installed xposed. Mine was rooted too. The problem is after somedays, I lost root access for no reason.
[ZenFone 2 General] Grid4:

[ZenFone 2 General] karfio:
Thanks Kapil, I made the root to zen and I Xposed installed. now I ask

I can upgrade directly from the Xposed?
[ZenFone 2 General] PepNYC:
Has anyone tested this on WW-4.21.40.184 yet?
[ZenFone 2 General] harpreet.s:
xposed caused loop when used with new update to 184
[ZenFone 2 General] PepNYC:
Aren't xposed and Magisk optional? What if you leave them out and don't install them?
[ZenFone 2 General] harpreet.s:
I used supersu and it isworking fine , removed Xposed , yep not necessary.
[ZenFone 2 General] PepNYC:
So if I'm currently rooted on WW-4.21.40.134 I'm assuming I'll have to remove the root, run the update and root again huh
[ZenFone 2 General] harpreet.s:
Yes, you have to install stock kernel and all xposed , root modifications will be removed. In case you changed recovery or other system files , remove those too.
[ZenFone 2 General] dcduartee:
It works as long as you don't flash xposed. It is causing bootloop for some users

HOW TO UNROOT :

More explanations :

1 - copy your last firmware in the memory of your phone

2 - rename your firmware like this : if actually you have already the last UL-Z00A-WW-4.21.40.184-user.zip rename it like UL-Z00A-WW-4.21.40.185-user.zip

So the phone will "think" there is a new firmware when you will start the phone later.

1 - unlock (see first post for method)

2 - with fastboot install original recovery (that you will find in the UL-Z00A-WW-4.21.40.184-user.zip (see first post for method)

3 - restore (see first post for method)

4 - restart your phone

5 - you will see a message for new firmware to install. If you don't see the message, you will get a notification with a ??

OK install it.

6 - wait a long time

7 - that's all. No more root
[ZenFone 2 General] msespindola:
Okay, I'm using a custom, and I simply can't install the framework, via the Xposed installer app, or via TWRP it simply won't apply!

I'm on the latest version, the rom is already packed with Magisk, root and Xposed, but it won't recognize the framework
[ZenFone 2 General] bemo00:
Thanks for the detailed explanation on how to unroot. I actually didn't need to unlock. I just installed stock recovery, then installed stock firmware.
[ZenFone 2 General] mike_saldanha:
Perfect

The root was done perfectly. I had followed each and every step correctly.

However, when I restarted my phone, there was an error for 5 sec on my screen.

"Your device is corrupt. It can't be trusted and may not work properly.

Visit this link on another device: g.co/ABH"

Then I restarted my phone once again and the root just disappeared.

[ZenFone 2 General] ekosemut:

I have success root in 184 version, xposed success installed but if we have install module after restart xposed status not active. Recovery lost but we can flash official recovery from fastboot and work normaly.
[ZenFone 2 General] mike_saldanha:
But when I restart the phone and go to the Root Checker app or Magisk Manager, it shows No root found or root not installed correctly. And xposed status not active as well.
[ZenFone 2 General] Osaci:
So I tried to unroot the phone by flashing the original firmware (UL-Z00A-WW-4.21.40.134-user.zip) from TWRP "install" section.

Turns out it didn't progress and I ended up having to force shut down the phone. Now it vibrates when turn on but the screen stays black. Computer won't recognize it either. So is this it, is it hard bricked? Is there any hope for this device or does trash can await?

Follow the soft/hard brick guide. Instructions might be hard to understand about the whole OS thing on your PC but once you get it - you get it.

On topic:

Followed the instructions and looks to be working flawlessly.

I use latest BORETS kernel and stock .184 - unlocked bootloader
[ZenFone 2 General] Osaci:
Yes! Managed to fix it by following this great guide. I went without the asus flash tool. However at the last step when flashing system.img, it wasn't able to do it for some reason. I then opened up the AFT and who knows it did recognize the real serial number. Flashed the raw firmware and the phone booted. :fingers-crossed:

Hope it helps.

Try to clean your phone

You can use this guide to clean your phone by this guide Click Here

This helps when you cannot reach bootloader, or stuck at asus logo.

Suggestion: If you only struck at asus logo (i.e you bootloader working fine)

then using restore.bat ( which is in unlock for zf2.zip) might help.

tell me if it works

well honestly after I installed the TWRP I was not able to flash SuperSU to it and it failed to root, I tried so many times and I found some suggestion to wipe everything the cache the system everything, and I did which was a huge mistake, I had to install CWM just to flash the original rom, I stayed up all night I worked on it over 8 hours cause I thought I had destroyed my phone, at this point I got no advice to anyone and I was too afraid to try and do anything on the CWM recovery so I just flashed the original ROM if you want to try....go ahead but I don't advise it, if you do try and it works, let me know how.

fastboot flash recovery twrp.img

If the downloaded recovery is not named twrp.img then rename it. Otherwise it wont flash.

Give it try and inform.
[ZenFone 2 General] Juanjo996:
Hi, I'm having troubles at this step too. I was able to flash it

But then when I try to enter Recovery Mode I can´t do it. The phone restarts and I get to the black Asus logo over and over again and after a while It goes back to the bootloader screen.

What can I do?
[ZenFone 2 General] Kapil Tapsi:
No Problem Should occur

There Are Two Methods Available

1. (Temporary But Fully Functional) If you cant access twrp then use unlock.bat given in unlock_for_zf2_551ml_6.0.zip (Steps are given in the post). Do your stuff (like flashing, wipe, etc). After that use restore.bat. This Method is temporary. After Using restore.bat Again you won't be able to use twrp, You'll again have to use unlock.bat.

Warning: After using unlock.bat you won't be able to boot rom, but don't worry After using restore .bat you will be able to boot, so no problem here.

2. (Permanent But Experimental , Need Confirmation)

Flash new twrp given in folder (Already Replaced), New Recovery Name is same i.e. twrp.img

Also link is there in the description as well as here.

http://www.theflamingskull.com/downloads/z00a/MM_BL_STUFF/TWRP-3.0.2-M1-Z00A.img

I flash with the stock boot.img and the phone works again but not rooted.

[ZenFone 2 General] rasyax:
I redownload the google drive and tried again. It is not working. Still stuck at loading screen.

Then I sideload the stock WW 21.40.184, boot it normally. Use the upgrade.bat to install twrp.img as recovery. Flash magisk and then superSU with twrp install (the other two not flashed). Boot to bootloader and fastboot flash stock recovery, then reboot phone. Still stuck at loading screen.

I tried to flash magisk then superSU the last time because I thought the problem might be magisk writes over the whole boot dir including the superSU. Before that I did it in the order of superSU, magisk, xpose, busybox.
