Z00AD. I have the 551ml 2gb.

Download an official ROM for your Zenfone 2 and the official recovery of the version of your rom.
Boot your phone on Fastboot mode
Start shell and type "fastboot devices"
If your device is detected, you're saved
Then type "fastboot flash recovery recovery.img" (with the .img in your recovery.zip)
Then boot in recovery mode -> Press power button + volume up button
"Apply update from adb"
Type "adb sideload UL-********.zip" on your shell
Wait and enjoy your stock rom

It's best you read and not get spoonfed for your answers. If you don't know what adb and shell commands then PLEASE don't install anything........

I know what ABD is, just not shell. I rooted it in the first place after all.

In this context shell = command prompt

So you must've flashed that raw file in AFT?
Then all you have to do is flash the latest raw instead .
Can I ask you a question.
Is your serial number correct in boot loader ?

the serial that appeared in aft ? ive think (123456789abcdef)
dont know if thats the correct format
right know im searching latest raw file for ze551 then flash it to aft right then after that?
where do i get the images files that ive flash in cmd like what ive do in previous unbricking method?
and flashing thru aft with latest raw file of ze551 will required that cmd command?

Don't do anything just yet , you need your serial corrected , which if not will affect your recovery
collection of raw files on xda by realyoti.
I think .194 LP is the last one he got
You only flash it in boot loader...using AFT .
It is important to do the two part flash in AFT for restoring serial.
Check my unbrick thread , for video and AFT download...from 2:17 mins in .
Before it is xFSTK flash ..which you don't need cause you already in boot loader.
AFT raw flash from 2:17 mins in, follow procedure , at 5:56 mins in -- cmds in blue on phone screen stays on `RESULT=OK` . Shut down , force close AFT , open AFT again - load it up with raw again and press vol+ once , and finish the flash -- serial number will be corrected now ! DO NOT dislodge the data lead while doing this procedure -- let the 2nd flash finish , it will boot into system by itself , recovery will now work correctly too !

in short i will do aft two times? .. then my serial goes back to normal?..
and after flashing latest raw files will my recovery goes back to normal what i mean is i go to recovery when wipe and format belongs?

My Zenfone 2 Got Bricked But The Problem Is Something other than Brick!!!

Hey Guys, My Zenfone 2 (Ze550ml) got soft bricked automatically after 3 days of rooting it. The Problem is not that 'I want to recover' the problem is that I rooted the device via a method displayed in the xda forum which is one-click root method.
The unbricking process is via ADB from cmd i did that but when i type " adb sideload <filename.zip>" and press enter then it shows
' error: Protocol Fault <no status>' So I tried to update the drivers and firmware and everything is up to date including drivers and all. But still it shows that, I don't know what to do now!! I consulted one of my friends he said that 'this because that while rooting none of the drivers were updated. ' So Now whats the solution for it.

I don't know much about boots and ROMs and fastboots. So i don't know what are they, and I haven't done that. if you have a link to describe the method to do that then it would be great!

How to downgrade from WW4.21.40.223 to WW_2.12.40.11?

Hi,
I have the flickering screen problem with my phone and it is out of warranty so i can't send it back to repair.
I tried upgrading to the latest firmware, tried factory reset, wipe cache, installing google launcher, enabling the HW thing in developer mode and nothing worked.
I read that WW_2.12.40.11 version doesn't have the screen problem and i want to try it, but i wanna be sure i'm doing it the right way.
1) I read that i can't just put the wanted firmware in my phone and install the update but i must also flash the matching recovery to flash the wanted version - is it true?
2) Can i downgrade straight from my version to the lower one because i think the other way around, i need to have higher version for upgrading to the higher version i now have.
3) Where can i find the adb driver for this?
Thanks

You can downgrade via ext sd card using the downgrade version from asus > 52.20.40.196 LP which when installed , reboots to 2.20.40.196LP
When putting WW-UL- 52.20.40.196.zip.zip ,make sure to put an extra .zip on the end in file manager or in sd from pc first and reboot.
If you then put WW-UL-2.12.40.11-user.zip.zip (extra .zip) on sd or in file manager . You might get that to give you notification after a reboot too. Although i have not tested to downgrade that far .
You must use the first 52.20 blah blah fw to initially downgrade first though. Ignore this and you are liable to brick. Here >
http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZE551ML/UL-Z00A-WW-52.20.40.196-user.zip
See my downgrade via ext sd video and thread , familiarise yourself with the process first !

Just a question before i try your method: I already installed 2.12.40.11 recovery.img into the phone. can i still use your method or should i first flash 4.21.40.223 recovery.img back to the phone?

OK, it's weird, i did flash the 2.12.40.11 recovery.img to the phone using adb and it was said in the console that the process completed, but now when i enter recovery mode it still shows me 4.21.40.223 version.

OK, I did downgrade with your method and it works great, but when i try to downgrade fro that version to the version i want to try i get error that i cant install the package over the existing newer version.
Just to inform.

If you want to downgrade to such an old version, find the .raw file of that version (search here on XDA) and flash it via Asus Flash Tool.

Thanks for the advice.
I searched and found raw firmware versions but no the one i'm looking for.
Is there any way i can install the official firmware i have? i also found recovery.img, boot.img, droidboot.img of the version i want.

If you have all the img partitions you can always try installing via fastboot commands but i really recommend using a raw with Asus Flash Tool...

Hi, thanks i'l try that.
does it matter in what order i flash this 3 files?
Edit: If i already flashed the ROM can i just flash the boot.img and droidboot.img or do i need to do the whole process including flashing the ROM again?

Is your screen flickering problem like this: https://www.youtube.com/watch?v=kRuxTefNcKw
If its like that I was told its a LCD hardware problem which gets fixed by replacing LCD.

Update:
Well, I installed firmware 2.12.40.11 and it worked fine for several days but then the screen started to flicker again.
i started to update the devices with OTA updates and then i saw that in firmware WW_2.20.40.174 the screen didn't flicker.
i had further updates and then the screen started to flicker again.
i tried to flash recovery.img, boot.img and droidboot.img but not the device only enters fastboot mode but when i try to enter normal boot or recovery mode, it only comes back to fast boot mode.
any suggestion what should i do to unbrick the phone?
Thanks

So where are you stuck?
Let's go step by step:
So you have unlocked the bootloader and now you have the stock boot img for you rom patched?
Have you tried to install the patched img through adb?
Fastboot flash boot nameofimg.img
Make sure is the patched img.
Once you do that you have to go to magisk web site https://******************/ download the lastest apk.
Install remember to allow your browser to install unknown apps.
Once that happens magisk Wil tell you that it needs to install some extra things let it do it and it will reboot.
I know you said you tried it but in this guide you also get the patched boot img.

when in fastboot if you write fastboot device does it show the number I'd of your device?
Also under developer option I guess you have advance reboot turned on and USB debugging on.?

Place the boot.img in the fastboot folder file. What I had to do since I had downloaded this fastboot zip but it was two in one, forgot the name but I had to put the boot.img into the file folder of fastboot so when I open adb or whatever it will detect the boot.img file.

As Yelloman said you do have to put the img file in the Fastboot folder in order for it to transfer the img to your device.
