Unlock bootload (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

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

@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

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*
