PS3 4.91 Evilnat Cobra 8.4 CFW Released

PlayStation 3 CFW developer @Evilnat has just launched the highly anticipated 4.91 Evilnat Custom Firmware (CFW) following Sony’s recent 4.91 firmware update last week. For users already on Custom Firmware, updating is straightforward—simply install this new CFW file via USB, no need to wait for an update to bguerville’s PS3 Toolset, as your system is already exploited.

However, if you’ve updated to 4.91 Official Firmware (OFW) or accidentally installed a Hybrid Firmware (HFW), you’ll need to wait for an update to the PS3 Toolset. Developer bguerville had been holding off on updating the Toolset until the first 4.91 CFW was available. Now that Evilnat’s release is here, bguerville’s update should be available soon, as discussed on the psx-place forums.

Evilnat has announced plans to release additional versions and variants of his 4.91 CFW shortly. These future releases will include OverClocking (OC) builds, PEX, NoBD, and others. Currently, he has started with the well-known Cobra CFW variant.

This initial release is a standard CEX CFW with the latest Cobra payload (v8.4) integrated, bringing extra features such as background plugin support and ISO compatibility—options typically unavailable in a standard CFW without Cobra (or the alternative MAMBA). For more details on the Cobra payload, you can check this forum post. If you’re comparing CFW and PS3HEN
