The file is not deleted and I downloaded it, but You need the kernel from post 567 for T380: https://forum.xda-developers.com/showpost.php?p=80863641&postcount=567I flashed Magisk many times but could not get root access. I think this file is what I missed. I am happy I found but sadly 'The file was deleted' Can you please upload one. I am very badly in need. Please.
But the core is the link: http://s000.tinyupload.com/index.php?file_id=04461652675934069019
P.S. Try it, but I think you need the core T380DXU3CSI5 from post 567 on the link above
