[HELP] I Need to convert my boot.img to a .tar file for use with ODIN

[AndreM962]

There are plenty of guides on the internet, but none specifically for Magisk. I tried compressing it with 7zip, but it doesn't seem to work. Help?

(EDIT: If this seems similar to a previous post - I got confused and thought I hadn't posted it here, so I made another one by mistake. Sorry!)
