Hfw-4.91.1-ps3updat.pup

Before proceeding, it’s vital to understand what this file does not do. Installing HFW-4.91.1-PS3UPDAT.PUP does not give you a Custom Firmware (CFW) like Evilnat or Rebug.

| Feature | HFW (This file) | CFW (e.g., Evilnat 4.91) | HEN (Installed via HFW) | | --- | --- | --- | --- | | Permanent after reboot? | Yes (acts like OFW) | Yes | No (must be reactivated) | | Allows unsigned code? | No (needs exploit) | Yes (directly) | Only after running HEN | | Risk of ban on PSN | Low (if using HEN) | High (unless patched) | Moderate | | Compatible with all PS3s? | Yes (Fat, Slim, Super Slim) | Only Fat & early Slim (CECH-25xx) | Yes (all models) |

Key takeaway: HFW-4.91.1-PS3UPDAT.PUP is designed for Super Slim models and later Slim models that cannot run full Custom Firmware. If you own an original “phat” or a CECH-20xx/21xx Slim, you would likely prefer a full CFW. But for everyone else, this HFW + HEN is the golden path.
