<![CDATA[Unlock bootloader (asus zenfone max pro m1)]]>I am trying to install custom rom (ubuntu touch at first) on my device:
Asus zenfone Max pro M1 - ZB602KL (dual sim)

But, i can't unlock oem (bootload ?)

I try many way to solve it :
1 - become developer of the device
then, Unlock usb debugging (no problem) and unlock oem (but, THE CASE DON'T EXISTE on the parameters)

2 - So, I tap ##CHECKIN## on the phone interface (I get the return "checkin succed"), but the case "oem unlock" not appeared.

3 - I tried to unlock with a unlock tool (https://www.thecustomdroid.com/unlock-bootloader-install-twrp-root-asus-zenfone-max-pro-m1/), but it doesn't works :
sometime, the bootloader shutdown and ask to reboot, sometime, the phone reset, but nothing more...

4 - I tried various fastboot commandes :
fastboot oem unlock - 'unknown command'
fastboot flashing unlock - 'unknown command'

5 - I tried some rooting apps :
ASUS "official" Unlock Tool
Magisk
Kingo root
... but doesn't works

Nota :
I notice the UBport installer detect my kernel as ASUS_X00T_2 (and it is)
I notices that the fastboot commandes not always work : the commande 'fastboot oem device-info
' give sometime 'FAILED - unknown command' an sometime the answer needed... (without reason)
I read that the AMD processor of my computer can cause difficulties with ASUS's fastboot mode...

Is there an other solution to unlock the bootloader ?

i found a guide on XDA to edit my registories on windows regarding USB ports.

Usb3fix.txt

FOR ANYONE READING THIS. PLEASE SAVE THOSE LINE IN A TEXT FILE AND CHANGE THE EXTENSION TO .bat AND THEN RUN IT AS ADMINISTRATION.

then i could run the unlock.cmd file and it ran flowlessly.

thank you for your help.

Attach the phone to the PC in fastboot mode. Open a terminal in the unlock folder. Run the command ./unlock.cmd. Note the ./ in front of the command.

19d8e878-25de-402a-8626-f2216cefb834-image.jpeg

it is still does not go further than this.

sometimes it stays in fastboot mode when i run the script and sometimes it leaves the fastboot mode with this laconic message "press any key to shut down".
if not that then it leaves fastboot mode as soon as i connect it with the pc.

NO FURTHER PROGRESS

It is not the easiest phone to install UT onto. The build number won't make a difference unlocking the bootloader, but when you unlock the bootloader use this (quote from devices page):

"The port is based on Android 9 firmware (WW-16.2017.2004.063) and Lineage 16 vendor image. Current Recovery will be replaced with Ubports Recovery!"

I think you are experiencing difficulties with the ASUS drivers. On Windows uninstall the drivers, reboot the PC, install the drivers and try again. If that fails try disabling driver signing which is a bit of a messy workaround. I found that one of the Windows updates messed with the drivers and uninstalling them and reinstalling solved it.

I tried it using Linux mint and also Windows 11 (fresh Asus driver installation)
Still facing the same issue on all platforms

Try running it in an administrative command prompt and run the command with ./ In front.

All my data is still there and I don't see any bootloader unlocked warning or anything

Could it be because of my build number or security patch?

I am using Android 9 with September 2020 security patch
Build number is WW 16.2017

Download the unlock.rar file (link still works). You don't need to root the device for UT. Follow these instructions and you need a Windows PC:

*DATA WILL BE WIPED SO MAKE A BACKUP

  1. Download this zip(you already have) and you'll get 2 folders 'unlock' and drivers
    https://drive.google.com/open?id=1YpezCedaRWGDS9WW7UaXXyyBod0Bk5qp
  2. Install the drivers and go the 'unlock' folder
  3. Reboot your phone to fastboot mode by pressing volume up + power on at the same time.
  4. Connect it to pc and open unlock.bat in 'unlock' folder
  5. Done*

Try fastboot boot recovery.img and see what happens.

This phone was not easy to work out, that’s why I put up what worked for me in the forum and it has worked every time.

Boot into Android and set it up - make sure everything works.

Then reboot to fastboot and install the TWRP image.

Then power off. then using the button combo to get to recovery, volume down and power - keep the volume down pressed until you reach TWRP.
