After some research on internet and xda i decided to try to relock my bootloader with the information provided by RealYoti, and this is how i did without causing a war conflict a Cthulhu evocation or a burning Zenfone
Anyway follow this guide at your own risk, turn on your brain and everything will be fine (hopefully)
Download these files
AFT: https://mega.nz/#!LcwhXDLZ!PN1jzQ0hD...QyvMzN8VK4fVBU
RAW: https://mega.nz/#!7cA3nTZC!NiHOzVoVP...axpE2es7lrwGpI
Install the Asus flash tool
Reboot your zenfone to bootloader
Open the asusflash tool
Select your model in the drop-down menu (under the button settings)
Choose if you want to keep the data or to wipe it all (i wiped)
Click on the box and the select the raw file you just downloaded
Connect your phone to the pc with the original usb cable
Now you should see your phone in the device list, check if all is ok and then start the flash clicking the green button on the top
Wait for 6-7 minutes and your phone should boot to android but now is recognized as ZE550ML, we have to fix this
Reboot to bootloader
Download from here (thanks to Shaka Huang) the last recovery set for the ze551ml (recovery.img droidboot.img boot.img)
Flash it from cmd:
Code:
fastboot flash fastboot droidboot.img
Code:
fastboot flash recovery recovery.img
Code:
fastboot flash boot boot.img
Now we are ready to flash the ZE551ML firmware download the last one from the asus support site
From the bootloader enter in the recovery
Apply update from adb/sideload
From the pc CMD type
Code:
adb sideload thezipyoujustdownloaded.zip
Wait
Wipe data/cache factory restore
Reboot
Enjoy your warranty
Let me now if there is any unclear passage
Thanks to:

I Tried to flash twrp after this procedure and it worked so the bootloader even with this method remains unlocked, it only reverts to stock
this is awesome in case you need to regain warranty!!
I Updated the first post, the bootloader after a deeper research remains unlocked, so the method with the raw file reverts only to stock
Inviato dal mio ASUS_Z00AD utilizzando Tapatalk
Very strange
To be frank, i didn't even gave a thought that it will work
In this way can I return to stock rom ?
I cant download the files from mega.
Waiting for an other method for relock the bootloader.
Hi everyone,
After I receive one notification for update the system the battery was over and the zenfone 2 didn’t boot anymore. I get into fastboot mode but I cannot access the options for recovery mode (factory reset, install from adb,…). I just have a few lines in the end of the screen:
E:file path:/tmp/last_install
… until
E:file path:/sdcard/MODF_SUPDATE.zip
After that I read lots of information from the internet (I’m not an expert in Android) and I figure out that my zenfone have firmware SKU CN. Then after read how to change CN to WW I install Intel USB Driver for Android Devices and I made the fastboot flash (droidboot.img, recovery.img and boot.img) commands to change recovery mode to WW (Z00A.2.20.40.59) and now I need to install the firmware UL-Z00A-WW-2.20.40.59-user.zip. The problem, as I said before, I don’t have access to Recovery Mode Options to, for example, install new firmware using adb (adb sideload UL-Z00A-WW-2.20.40.59-user.zip) command. Now when I make a normal boot it stops after a little bit of “Installing system update” and showing android symbol.
Anyone could HELP, PLEASE?
Thanks
I have the Zenfone 2 and it is stuck in bootloop.
My brother boot it to CWM and flashed Paranoid Android without unlocking the bootloader and flashing TWRP. Now the phone stuck in bootloop, i tried flashing system.img the stock one but it is telling me that system.img cannot be loaded. What should i do? It is now bootlooping. I dont know what to do.

Hi, I unfortunatelly am not able to solve your Problem, but maybe you could help me with mine. Could you pls upload the System.img? I am only able to find *.zip and adb doesn´t want to Flash it at all
Thanx in advance

Go to Original Android developement. It's in the pre-rooted thread, these are the ONLY img files for roms available unless you push the zip file using ADB...
Flash the system zip file rather than trying to flash simply the .img. The zip files are in this thread (http://forum.xda-developers.com/zenfone2/development/asus-zenfone-2-rom-t3054956) and might help because you're also flashing default recovery... could be CWM.
Also try flashing using fastboot.
your phone model?

What worked with me, Problem is simmilar, I flaged the Boot.img and androidboot.img, which Werke attached in the custim Rom folder, too. Without that, I gut stuck at the Boot Logo, now all works fine and I am trying to be up to date with the Roms.

1. download the latest recovery from here https://dl.twrp.me/Z00A/ and firmware from here http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZE551ML/UL-Z00A-WW-2.20.40.97-user.zip
2. download and install adb and fastboot driver from here http://forum.xda-developers.com/showthread.php?t=2317790 and intel usb drivers from here https://software.intel.com/en-us/android/articles/intel-usb-driver-for-android-devices
3.the adb driver should have installed in your pc OS drive [ which is C: ] put the downloaded recovery and firmware in that folder [where adb is installed] then in that folder, open command window by pressing shift and right click and a dialogue box will appear then open the command window from there and enter this command fastboot flash recovery {name of the recovery twrp something}.img then connect your phone to your pc and enter bootloader in your phone and press enter in command window.
4.after that put the downloaded firmware in any sdcard and put it in your phone then open recovery mode in your phone and go to reboot>recovery [yeah you have to reboot the recovery] then when recovery open again then go to wipe>advanced wipe> and select system,data,cache,dalvik and internal storage [internal storage is optional but if you choose it then it will wipe all your data in your phone] then wipe it and go to install section then choose the extsdcard [it should be written internal storage click on that then you can choose your external storage] then in the extstorage choose the firmware you downloaded and just swipe to flash.
5.patience ..because it would take time and maybe get stuck at 52% or 59% ..so just let it take time for installation [btw connect your phone to thr charger in this process]
6.after it done then reboot your phone and ALL DONE. [the first boot will take some mins to boot up]
Sent from my ASUS_Z00A
Hello, I have sent my phone to warranty and after that I received a phone with NO RPMB and after many frustrations I found (with help of many users and forums) how to workaround this..
To start:
Download boot image from here
Download twrp from the official website
Change the name to boot.img and twrp.img and put it in the platform-tools folder
Open the terminal there
Download your favourite rom
Enter fastboot mode on your phone
!!!!After this you will loose all of your data!!!!
Paste this to the terminal
fastboot oem unlock
(select yes on your phone)
fastboot flash boot boot.img
fastboot flash recovery twrp.img
fastboot format userdata
fastboot format cache
Reboot to recovery (if it doesn't enter at the first time enter download mode again and restart to recovery)
After that you have twrp and can flash every rom.. yay!!!
Wipe everything.
Copy the rom zip to your phone using MTP
Install your fancy new rom
If you want to install magisk:
Install the magisk manager.
On the app select install and select patch image file. (it will create a new boot image already patched)
After that install the new image (patched_boot.img) using twrp
Do a clean instalation of your ROM (recomended) or a Factory Reset first
Reboot to twrp
Select install
Click in install image
Select patched_boot.img
Select install to boot partition
Reboot.
Install magisk manager and do the sugested setup.
You now have magisk working
Thanks to all the users that helped me!!
I had real trouble getting twrp to work the last time I tried this a few months ago. Followed the steps here and am now on pixel experience with magisk. Thanks!
Hello, im in the same situation of NO RPMB. This procedure will permanently lets have bootloader unlocked?
About Magisk, i can install it in usual way once im in the recovery? (I mean download latest stable version for Bullhead and flash via TWRP).
Thanks.

My bootloader is still unlocked after following this guide
For Magisk:
-Install your custom ROM and boot it up (without root)
-Then extract the boot.img from the ROM zip file and save it on your phone storage.
-Install the Magisk manager apk
-In Magisk manager, select install Magisk> choose the patch boot image option and -Select the boot.img you previously saved.
Once it's done, reboot into twrp and flash the patched boot.img. When you reboot Magisk will be working.
I've had no issues with my bootloader, even after an ota update for pixel experience.
Thank you, i will try it.
Another question. I never tried dowload mode before, as i read in other post i should Plug USB cable into pc, Hold volume up and power at the same time and plug phone into usb that's already connected to pc, right?
When in download mode i can fire up fastboot commands like im in bootloader mode?
So then after do last command fastboot format cache i can reboot to recovery from terminal using adb reboot recovery or i can / should do it from device?
About twrp it's ok to use the latest 3.2.3.0 official version or the 3.2.1 4core version from here as someone suggested from Reddit? https://forum.xda-developers.com/nexus-5x/development/recovery-twrp-3-2-1-4-core-t3796656

The official twrp works for fine for me, haven't tried the 4 core version but it can't hurt to try if you need it.
Power off your phone then press and hold volume - and power to enter bootloader, then connect to your pc and follow the steps in the OP
So i have to enter in bootloader mode? At point 6 of OP there is written to enter in the download mode, this makes me confusing.
Can anyone explain me latest 2 commands why they are needed?
fastboot format userdata
fastboot format cache

This thread is fairly comprehensive;
https://forum.xda-developers.com/nexus-5x/general/moto-nexus-5x-sticky-roll-t3207487
Holding volume - and power takes you to fastboot mode (download mode essentially), theres also an option to reboot into recovery (selectable using the volume keys.)
Formatting user data and cache is necessary prior to installing a new rom (especially if moving from stock). You lose all data (back up first!) But a clean flash is the best place to start.

Thanks for the explanation but for installing a new ROM usually you can do factory reset directly in TWRP, plus doing all the wipes, this should be enough.
About fastboot mode and download mode, they are completely different, fastboot mode: vol down + power, download mode for LG: Plug USB cable into pc, Hold volume up and power at the same time and plug phone into usb.
My question is what i can do in download mode? As OP says after entering download mode open terminal and use fastboot commands.

You need to use vol- and power to go into fastboot mode then connect to the pc. As for userdata and cache, if you don't clean them when coming from stock you will have issues (your data will be encrypted if you're on stock?). As I said this guide worked for me. The op was talking about fastboot mode in the 6th option (also there is much more information in the thread I linked above)
sorry for the confusing i wanted to say fastboot mode..
i knew the thread that you are saying but most people doesn't want to search so I made a little thread only with the needed parts..
I use it myself so I have a place to remember all the steps when I need to change the rom to a new one or when I make experiments and brick my phone XD
If anyone know anything else that should be in here just say, I really want to improve the post
Hi. I just went through the whole process several times (I have tried the different modified boot images from the dedicated post) and my device is still locked [emoji24] any suggestions?

your device will always be locked this is a workaround to get twrp, new roms and magisk while it stays locked..
with twrp usable it won't matter if you are locked or not

Thanks for the answer. You mean that now I have twrp, I can flash custom Roms with my bootloader locked without any issue?
Envoyé de mon ONEPLUS A3003 en utilisant Tapatalk
Yes if you have TWRP you can install custom ROMs, custom Kernel's, magisk, super su, etc..
the locked bootloader only prevents you from using fastboot commands like the one needed for installing custom recovery
Now that you have TWRP you can use it for everything
Hello everyone, I also have a nexus 5x with motherboard that has been replaced under warranty and unfortunately I can't keep the bootloader unlocked.
I tried the procedure you have indicated, but at this point there is the problem, because after inserting the boot.img and twrp.img inside the phone, then when I go to do the unlocking procedure with 'fastboot oem unlock (select yes on your phone) 'in practice the memory is deleted on the phone, so I lose the previously uploaded files, and therefore I can no longer continue with the flash procedure of boot.img and twrp.img because they are no longer present in memory.
I hope I made myself understood, maybe I am wrong, or is there a way to solve this problem?

fastboot is for the files on your PC not your phone
you need to put the files inside of platform-tools and then open cmd inside it and use the fastboot commands
fastboot will take the files of your PC
Hello, thank you for your information, since I haven't done modding on phones for a long time, I didn't remember exactly the procedure with fastboot and therefore I didn't understand where I had to put the files, but in the end I did it.
Thank you

Why is a custom boot image needed? I don't want to root.
⚠Warning: This is not official TWRP, use it at your own risk!!!
Data will be erased. Back up if neccessary
This device is kind of weird so to flash twrp you need these things:
1. Prepare materials
Install driver so as to have access to preloader (Just install automatically and no need to do anything in device manager)
This software to access to preloader -> fastboot (fastboot is somehow not available via adb methods) Enter fastboot
This tool for flashing
2. Unlock bootloader (need testpoint, python, git (optional) - you can search on google)
Use this tool - go to this section. Follow guides to unlock bootloader (remember to use testpoint not hardware buttons)
3. Enter fastboot mode
Use latest MTK META Ultility tool
Select Reboot Fastboot Mode in BRom section
Hold volume down button. While holding connect it to your computer
*Now your phone is in fastboot mode4. Flash
Open platform-tools folder in Downloads folder
Shift + Right click then "open command window here"
Input these commands into cmd
fastboot flash boot drag twrp file to cmd
fastboot flash recovery drag twrp file to cmd.
fastboot reboot. Swipe to allow modification in twrp (to make sure that stockboot wont replace twrp). After that reboot to recovery to make it installed on your device permanently.
Now your recovery is ready to flash file you can push stock image file to your root folder using adb command: "adb push. Drag the stock image file. /" (Because Decryption right now doesnt work on my device yet)
Enjoy
*Sounds crazy but it is required to make sure twrp is installed correctly*If successful, when you power on, you will get a red section on top of your device. If you want to recover to stock recovery, flash the recovery.img below.*Also, if you want to make your own twrp, you can try recovery.img below.
Also thanks SebaUbuntu and Mofadal El-Tayeb (مُفَضَّل) for awesome apps
Here is the PBRB version for this device
