The file HFW-4.91.1-PS3UPDAT.PUP is specific to the 4.91 system update. It swaps out a specific component of the newer system (the silk_modules) with an older, vulnerable version from firmware 4.82. Why is this swap necessary?

Hybrid Firmware (HFW) 4.91.1 for PlayStation 3 is a modified firmware designed to maintain PS3HEN exploit compatibility on the 4.91 system version by using a patched "silk_webkit" module, allowing access to the PlayStation Network while supporting homebrew features. This firmware allows users to install tools like PS3HEN to enable homebrew and is installed via a FAT32-formatted USB drive, with options for installation through Safe Mode if necessary. You can find instructions for updating the system software via PlayStation's official support page at PlayStation . Update system software in safe mode - PlayStation HFW-4.91.1-PS3UPDAT.PUP

Finally, there is the human dimension: the small, private stories nested around the update. A teenager hesitates to install it because of saved game exploits that would disappear; a repair technician keeps an archive of older PUP files because a client’s brick can be resurrected with the right image; an archivist collects firmware as evidence of a platform’s life. Each action — click to update, refuse, mirror the file, rollback — writes a line into a larger story about how we relate to our devices and to one another through them.

If you have a SuperSlim, you can only use HEN on HFW. Do not try to install CFW, as this may brick the console.

: Official firmware patches security vulnerabilities. By bringing back an older module, HFW introduces a known vulnerability back into the system without losing the features of the 4.91 update.
