  1. Hey,
    I doubt the renaming part. You told me that you have to copy the boot.img.lz4 to the LZ4 installed file, and from there, you told me to rename the lz4 file, so which one is it? is it LZ4 or boot.img.lz4 . And secondly, how do you copy the renamed .img file. To your mobile? to install in magisk?.

    • After yo9u converts the .lz4 file to the .img file, There is no need for rename. It will automatically convert the file to boot. img.
