LG KDZ formats are a pain in the ass. Various tools and scripts have been made for the extraction of said KDZs; not many, if any at all, work with the current KDZ format (v3).
The script mentioned below for extraction should work with all three formats, i.e old, older, and new.
- Windows (preferably with WSL), or Linux/Mac with a Windows VM
- NOTE: Unfortunately I am not yet aware of a method for Unix systems that does not require a VM or Wine for the time being. Looking into the 7zip method of extraction may fix this.
- Python 3 and Pip
