PS3 4.92 Evilnat Custom Firmware (w/ Cobra v8.5) Released - CEX,PEX,D-PEX,DEX builds

UPDATE xai_plugin: New Overclocking Tools (change on the fly) / New ps2netemu improvements added.

.Following the 4.92 firmware update developer's from around the community have been updating various projects. This time around PS3 CFW developer @Evilnat drops by the forum and leave's us with a suite of ps3 custom firmware's that support 4.92 firmware. 4 Flavor's (CEX, PEX, D-PEX & DEX) are available for 4.92 Evilnat CFW, depending on your console/taste, all builds are equipped with the Cobra v8.5 payload to provide expanded feature set over Standard CFW's.

If you are already on PS3 CFW, updating is a breeze, you just need to install the new CFW PUP file via the official USB Method and you will be on Evilnat's latest release. If you have updated to 4.92 OFW you will have to wait, as you will have re-exploit your ps3 console to allow for a Custom Firmware installation once again. The good news is that developer @bguerville should be rolling out a new update soon for the PS3 Toolset that support 4.92 firmware. The offline tool CFW Flash Writer may take longer for the community to update it, but we hope to see an update for that tool soon as well.

    .Updated xai_plugin to version 1.23 and EMUs MOD to version 1.10

    xai_plugin Updater [v1.23]
    ps2_netemu.self (MOD)
    • Updated ps2_netemu.self, implemented manual/auto/SYSCON temps (By kozarovv and mrjaredbeta)
    • Fixed FPS display to not show random values for the first 1-2 seconds after enabling the menu
    • Added Fan Control (Manual and Automatic)
    • Added current Fan Settings display (Select button in the main menu, also when changing the current fan mode)
    • https://github.com/Evilnat/xai_plugin/tree/latest_release/EMUs

    WARNING! New fan related functions require a single patch in LV1. The emulator is not compatible with firmware that lacks that patch. (https://www.psdevwiki.com/ps3/Talk:...em_Manager_to_allow_PS2_emulators_Fan_Control)

    To set manual mode fan speed, in the main menu press SQUARE and:
    • Left D-pad: -1%
    • Right D-pad: +1%
    • L1: -5%
    • R1: +5%
    In manual mode, fan speed is limited to a 21% - 80% range. Trying to go higher does nothing, trying to go lower re-enables Syscon Mode automatic fan control. WARNING! Keeping your fan speed in the range of 21% - 30% for a longer time can be harmful to the PS3! Remember that when the FAN is set to manual speed, it will not ramp up if the PS3 is overheating! Use the 21% - 30% range only if you are 100% sure that your PS3 is not having overheating issues.

    To set a new automatic fan speed mode, in the main menu press Square + Start

    This mode has 4 different settings available (toggle them through the next START + SQUARE presses). Modes are 60°C/65°C/70°C/75°C. This is the maximum temperature that the new auto mode will try to maintain by changing the current fan speed. At first, the fan speed can be a little high, but give it 2-3 minutes and it will find the lowest fan speed that ensures the selected temperature is maintained. When the mode is 75°C, the next press of START + SQUARE will revert to syscon mode.

    Credits
    • Thanks to @kozarovv and @mrjaredbeta for his great research about PS2 EMUs
    • Big thanks to kamilb880 for testing this so many times
    • Evilnat and @aldostools for original cobra fan control algorithm, on which auto mode implementation heavily relies on
    EDIT:
    The new emulator FAN Control will work on CFW 4.92.2 due to a patch in LV1 which does not exist in previous versions.
    The patch can be enabled in 4.92 by patching LV1 with 0x60000000 at address 0x16914C (Thanks to kozarovv and @mrjaredbeta)

Hi @Evilnat, I have everything on DEX at the moment. I tried it on CEX and experienced sound errors, but only with Metal Gear Rising and i have not Oblivion. I tried it with and without overclocking—the results were the same. I have a CECHA00 and haven't noticed excessive white. However, if I reset my DECHA00A to factory settings, the issue returns as soon as I set it up and download everything. I'm currently using the latest Webman MOD version, I believe it's 1.48.

Hey hey, where the heel did you get WebMan Mod 1.48? GIVE IT TO ME! xD ^^

Latest so far i know is 1.47.47
 
My BD is messed up, but I still have BT working excelently. I used to use the OC version, but there isn't a NoBD OC version. Is there someway to find, request or make it?

Nat usually doesn't make OC versions of NoBD variants, as these consoles are mostly useless, often resulting in black screens and other issues.

However, you can enable OC yourself using MFW Builder.
 
Hello, I am searching for a 4.92 with the GPU speeds 700/1000 for both of my PS3s 2501A
I only have a phone and limited cap and do have a USB hub that supports my USB drive to unzip it

Thank you.
 
I think I might have found an issue with QA Flags for downgrading when having a certain Syscon firmware. I have two Sony 65nm Frankie systems, A00 and C04. They have the F29 Syscon firmware. Both have this problem.

When I try to downgrade either with QA Flags turned on, I get a data corruption error. It is specific to these two systems with F29 Syscon, it does not affect my Sony 40nm Frankie F38 systems. These can downgrade just fine, so it makes me think the F29 Syscon is the problem.

Any suggestions?
 
Thank you so much for this update! I am new to PS3 CFW so this'll be my first time updating from 4.91. Hope everything goes well! Thanks again to the devs and contributors!

Hey, I have now HFW with HEN, now trying to install the CFW but keep having the update broken error...
Is it because I was on the 4.92 OFW before ?
I'm trying to install Red Ribbon on my PS3 lol, and going on CFW Evilnat is the only trick I found to accomplish that..
So I basically need Evilnat now

CFW PUPs will only install using BgToolset (which is not available at the moment). So, any modified PUP will fail.

You'll have to install HEN until the server is back online.
