Asus Zenfone Max Plus M1 [X018D] bricked – some advice to recover data ?

To be honest I’m a newbie here, and not really experienced on mobile phone technical stuff
My Zenfone suddenly stopped working last week, without any particular reason.
The only thing I can see when I on the device is the “Powered by Android” logo. But nothing else happens after.

Then I wanted to start the recovery menu, but even when I select “recovery mode” or “fastboot” nothing happens, it’s still showing “Powered by Android” logo and no more
See this screenshot :

I tried to plug the device with USB to my linux laptop with android studio installed, but adb devices show nothing

I also tried to create a microSD card, bootable, with exFAT partition and put the phone firmware on the root of the card (as described

My idea was to be able to boot from sd card and be able to “revive” somehow the phone, and at least being able to download user data from it with the help of adb

I’m not sure if it’s possible of if I should prepare the microsd with another format or partition layout

Any idea to guide me ?
