PS3 - [Update Re-Release] PS3 Custom Firmware - 4.91 Evilnat Cobra (8.4) CFW Released (2024)

UPDATE - See 1st post for details, Re-Release a few bugs corrected

PlayStation 3 CFW developer @Evilnat has just released his much anticipated 4.91 Evilnat Custom Firmware following the recent routine update from Sony when they dropped firmware 4.91 last week. If you are on any Custom Firmware currently all you have to do is install this CFW PuP by the USB method. You will not need to wait for an update to bguerville's PS3 Toolset to exploit your system (as its already exploited if you are running CFW).

If you had updated to 4.91 OFW or by mistake installed a HFW you will have to wait for the PS3 Toolset to be updated. Developer bguerville was waiting for the first 4.91 CFW to drop before making his update and that has just occurred with this release, so it should not be to long before we see bguerville provide a 4.91 update to the toolset as the developer described here in the psx-place forums..

Evilnat has plans to provide more versions and variants of his 4.91 CFW in the coming hours as of writing this. Those upcoming flavors would be OverClocking (OC) builds, PEX, NoBD ect... Currently the custom firmware developer has released first the popular Cobra CFW variant to start things off.

This is a standard CEX CFW + has the most recent Cobra payload (v8.4) injected into the firmware which allow's various extra features like background plugin support, ISO support among other features not found out of the box on just a Standard CFW without the Cobra payload (or the alternative MAMBA). For additional details about the cobra payload you can checkout this post here in the forum for information. If you are looking at the difference between CFW and PS3HEN you can checkout this post from the forum as well.
