Step 1: Unlock the Galaxy A02s Bootloader

As a result, you need to unlock the bootloader before you proceed with the next step. Follow this article to learn how to unlock the bootloader on the Samsung Galaxy A02s.
Step 2: Patching the firmware with Magisk

- Extract the original non-patched firmware. Copy recovery.img.lz4 and vbmeta.img.lz4 to the same folder where you put the boot image.
- Create a .tar file using the three files. You can use any programs for this, such as 7zip.
