Alright' I think the issue is solved: after all action to have root, it was necessary to wipe again cache,dalvik,internal but without system. Then just restart and yet another done automatically and: voila
Many thanks for provided procedure, files and inspiration

Moreover - it's worth to note - this root is persistent and doesn't disappear after shutdown.

Regards!

Step 0: Prereq
Download all the zip files from the main page on your phone and put them in the external SD card.

How to enable developer
Goto settings -> About Phone -> Software Information -> Tap "build number" 5 times

Enable OEM unlocking
Go back to Settings -> Developer options -> Enable "Oem unlocking" (if you do not see this option OR its grayed out try to connect your phone to internet, or follow this https://forum.xda-developers.com/gal...s-100-t3823361)

Note: Enabling OEM unlock here does not mean your OEM is unlocked! This switch only allows you to unlock it..Also enable USB debugging.

Turn off your phone.

Next: hold UP + Power until you will see a green screen. It must say "Hold long up to OEM/bootloader unlock." Follow those steps, to unlock it.
Congrats, now your OEM is unlocked. Turn off your phone.

Install TWRP
Hold UP + Power again. In the screen select "wipe data (factory reset). Then select Turn off Phone (should be one of the lower options)

While phone is off, hold UP + DOWN volume and attach USB cable to your phone. It should go into download mode.

In Odin, put the TWRP_A40 image in AP
Un-tick Auto reboot in the options tab.

Remove usb cable.

Tricky part: hold 7 seconds down+power. As soon as screen goes black hold UP + power!
Now you should be in TWRP!!

Once inside TWRP
Flash all the zip files you downloaded to your SD card
Go back to main menu, select reboot -> Recovery. Then reboot normally.

Enjoy =) Android must now boot up normally.

So I followed the instructions above, but I can't seem to get it to actually boot into TWRP, the phone just keeps on rebooting (unless I press UP+DOWN with USB plugged in to get back into download). Odin always indicates it flashed successfully. I have uploaded photos here: https://imgur.com/a/JrdnV23

Any hints? Thanks!

Your help is highly appreciated: I just tried to update to the new Magisk version on my rooted A40. Now it's stuck in boot-loop. Is there any possibility to get access to my data? I am running AGS1 firmware (July 2019 patch). Thanks in advance!

Won't boot
Hi,
I installed TWRP without a problem. Used the multidisabler and then tried to install a Lingeaos ROM (GSI). Seems to works too.
But it won't boot the ROM. Whatever I try, even different versions and yes I'm using the right one (a/b?). It seems that flashing the ROM goes to fast maybe, its done in 20 seconds. No log, just a message that it is succesfull. I've got the latest stock image. Could that be the problem?
I installed Magisk too, and flashed it after installing the ROM and before installing.. but no effect. It wont boot. Restoring to stock works (thank god). Someone got an idea what to do next? Thanks!
