Help Need Meta-inf

So, my phone recently got soft bricked....
I had the tar file of the XXELK4 leaked firmware and i extracted it, unpacked system.img.
Mounted it as ext4 and extracted the contents.

I want to make a flashable zip file from the system.img contents.
I made a folder called system. In which all app, bin, etc and other folders are.
Then i copied over the boot.img from the tar file...

Now, i need the meta-inf. I tried using some meta-inf from other roms, and removing the aroma functions from them.
Then trying to flash..

I get only a bootloop.
So, could someone provide a clean Meta-inf consisting of only the updater-script and update-binary??
