The zip passwords were quickly found using the strings command. The password for each model consists of the model name followed by !LGahslxjqlalfqjsgh!@#:

• 22MD4KA!LGahslxjqlalfqjsgh!@#
• 24MD4KL!LGahslxjqlalfqjsgh!@#
• 27MD5KB!LGahslxjqlalfqjsgh!@#
• 27MD5KL!LGahslxjqlalfqjsgh!@#

Is there any way to upload firmware from one 27MD5KL and download it to another 27MD5KL?

LG Screen manager immediately fails to update with these files. Is there some other way to apply the firmware updates individually after unzipping the contents?

LG screen manager fails to install for one of my monitors. I noticed that it shows up as Hardware DDC controlled vs Apple Native like the other ones. Is there anyway to install the firmware without the LG Screen Manager app (tried setting open with rosetta as well)?
