Unlock bootloader (asus zenfone max pro m1)

DJac

@MrT10001 So
1st time : the bootloader shutdown with this laconic message "press any key to shut down"
2nd time : the commande windows close quickely and... nothing apprently. I push the recovery image (fastboot flash recovery XXX.img) - return to the "laconic message". But now, the 'fastboot device' commande obtain unidentify device ('????????? fastboot')
3th time : same as the 1st, but i return to bootload mode. And the phone reboot (as factory reset)
When i whant to flash recovery :
'Warning: skip copying recovery image avb footer (recovery partition size: 0, recovery image size: 27062272)' > I think it is the problème with my computer

DJac

Infact, when i check 'fastboot devices', the next fastboot command give always the "laconic message" on the phone (black windows with "press any key to shutdown").
The other command seems not having this problem

MrT10001

@DJac The bootloader looks like it is unlocked. 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.

@DJac Yes it's an ASUS phone, you have to unlock the bootloader through the unlock tool. 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.

@MrT10001 Thankyou !! It works !
you are right : it works only with ubunutu (Lubuntu for me). that's doesn't works with debian (or windows).

MrT10001

@DJac Is it up and running with Ubuntu Touch?

DJac

@MrT10001 I can't install ubport on my 32bits ubuntu computer. and it don't work with my debian computer... so, I'm looking for others solution.
I have a probleme to install postmarketOS too.
I keep you in touch.

@djac @mrt10001

I am trying to unlock the bootloader of my Asus device. Can you guys help me? Are there any ways which I can still use in 2026??

MrT10001

@MadDino Check here. 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

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

@MrT10001 hey..

thanks for this. i tried but it just does not seem to work.

all i get is

Begin fastboot flashall
Earse Data: Yes
Support All device

I do not know what else to do!!

And the bootloader shutdown with this laconic message "press any key to shut down"

MrT10001

@MadDino Start the device up and the bootloader should be unlocked.

MadDino

@MrT10001 unfortunately not

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

MrT10001

@MadDino The build number should not make a difference. Try running it in an administrative command prompt and run the command with ./ In front.

MadDino

@MrT10001 i see. Does the cable which I am using for the connection make any difference?

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

MrT10001

@MadDino I have used Windows 11 to unlock the bootloader and install UT my ASUS devices. 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.

MadDino

@MrT10001 i tried all that too

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

MrT10001

@MadDino Put the unzipped folder on your desktop. 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.
