Updating ps3 via cd

PUP file downloaded from the Playstation System Software site to update my PS3? Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count).Copying it to the root of a USB flash drive doesn't seem sufficient. Would you like to answer one of these unanswered questions instead?

If not, there may be little point in taking the risk by updating.

To make a USB drive bootable, you will need a utility such as Rufus or Unetbootin.

You will need a ISO image as well, and Free DOS is the most appropriate for installing BIOS updates.

Your computer's BIOS - Basic Input/Output System - is a chip on the motherboard which contains enough information to allow it to start up before the main operating system begins to load.

However this isn't always the case, even for new motherboards or laptops, and it's possible that you will have to create a bootable CD or USB drive and copy the files to that.
