What does this do? It's just the bootloader, right? Where is the updated ROM?

Just a warning: After successfully flashing latest stock ROM (DUC7, rooted with Magisk) I also flashed the Kdragon_safetynet-fix-v1.1.1-s20.zip (from the downloads mentioned in the instructions) with TWRP and get a bootloop. So I have to reflash everything again and maybe try to flash the Safetynet module right in Magisk.

This is the old one. I use safetynet-fix-v2.0.0-test2.zip It works. U can flash it with magisk or TWRP.

Thank you for Netsafetyfix. I installed it through Magisk first but it didn't work. Then through TWRP and it worked. Of course, I turned on MagiskHide and the message Certified is correct. But it was only possible once, and in a moment the certificate was incorrect again. What am I doing wrong?

    I wanted to ask the same question. But I am afraid the vbmeta für DUB5 will not work with DUC7.
    No worries, it works with DUC7.

    A great guide. This is just a manual for firmware and TWRP update, but to get root you still need to extract boot.img, patch with Magisk and then flash with Odin, right?
    Flash Magisk (stable)
    6. TWRP - Multi-Disabler Firmware
    7. Reboot TWRP - Flash Magisk (stable)

    or Patching Boot Image
    This is required only If you want to root device without installing custom recovery (TWRP).

    Here is Patched kernel to root
    Unzip the boot.img from AP and copy the file to your device.

    Press the Install button in the Magisk card

    Choose “Select and Patch a File” in method, and select the stock boot image

    Magisk Manager will patch the image to [Internal Storage]/Download/magisk_patched.img.
    Now you will have Magisk_patched.img file in download folder - Copy that file to PC.

    Rename that magisk_patched.img to boot.img (Name must be exact same).
    Make sure your PC have 7-zip installed, If not get and install it.

    Right click on boot.img and select 7zip - select "add to archive" - select archieve format as 'tar' - and name it Patched_Kernel (it will be like Patched_Kernal.tar). Don't keep space in name. This will create a Odin flashable patched kernel

    Reboot to download mode. Open Odin on your PC, and flash Patched_Kernal.tar as AP.

    Reboot and Done !
