PS3 4.89.1 HFW (Hybrid FirmWare) -

This official HFW 4.89.1 release was created by @littlebalup and has been tested over many consoles and situations. Please be aware of several "Unofficial" HFW 4.89 builds that are on the internet. Some of them may work, and some of them are known to have problems.

HFW, by its very nature is a modified version of original OFW, that by itself can be unstable or have unexpected results in some situations, due to the system files (sprx) replaced with older version during the creation process. HFW is meant to be accompanied by PS3HEN, which when fully installed will restore HFW back to a stable OFW state (system sprx), and also includes any other fixes needed.

The official HFW 4.89.1 has a EULA date of May 11, 2022 and an MD5 of 1746FD1A7BA9F6DBB9428C9C64B54B0A

This firmware has been tested with PS3HEN 3.1.0
