CFW 4.30 on Playstation 3 with OFW 3.56 is now possible *HW Flasher Required*

[GaryOPA]

Flasher still needed

Varicela and Luckymas sceners have discovered a method to install a 4.30 CFW on Playstation 3 consoles that runs at least OFW 3.56

We have very good news on the scene side of Playstation 3. Spanish sceners Varicela and Luckymas have found a way to install a custom firmware (4.30 to be exact) on consoles that runs at least, an official firmware version of 3.56 installed by default (A.K.A you bought the console with this firmware already installed) but it seems that it works with consoles with firmwares up to 4.31 or also below 3.55.

This is a translated version of the original post at Elotrolado.net:

For you all that got a PS3 with 3.56 firmware, you're in luck.

Varicela and Luckymas and I have managed to install CFW 4.30 E3 in these kind of consoles.

In addition, we want to add that these patch are already valid for installing 4.30 CFW E3 from any OFW not higher than 4.31 or in consoles with a firmware below 3.55, skipping the downgrade process, the use of a dongle and the factory method.

At the moment, this only works on NOR memories, the NAND ones will be updated once we test it.

The following patches are needed: Patchv1 Three Musketeers

There is no need for a dongle but you need to use a flasher for getting our dump. Several tutorials are available at Elotrolado.net to perform this with progskeet, E3 or tensy.

Once we get or dump, we need to patch the following offsets:

patch1 : OFFSET 0C0010 LEGHT 6FFFE0
patch2 : OFFSET 7C0010 LEGHT 6FFFE0
patch3 : OFFSET 80000 LEGHT 20000
patch4 : OFFSET A0000 LEGHT 20000
patch5 : OFFSET 40000 LEGHT 20000
patch6 : OFFSET 60000 leght 20000

Once patched, we write it with a flasher, power on the PS3 and it boot up in recovery mode. We need a flashdrive with the CFW 4.30 E3 on the PS3/UPDATE folder to install.

TESTED ON SEVERAL 3.56 OFW FACTORY CONSOLES (WE SUPPOSE THAT FACTORY OFW 3.60 CONSOLES DOESN'T WORK BUT WE HAVEN'T TESTED IT)

WE ARE NOT RESPONSIBLE OF ANY MISUSE OF THIS METHOD.

INFORMATION TO CONSIDER:

• OFW 3.56 factory Playstation 3. You will not be able to downgrade from 4.30 but you can upgrade with future patches
• These patches are only for installing CFW 4.30 E3. Any other CFW will show you "Corrupted data" if you try to install them from the Recovery menu.

A video of the process has also been released for you all to watch.

Our thanks to 'Kaos2K' for this news item!

I wonder why it only works with the E3 CFW.

[Cyberskunk]

This has always been possible on any PS3 that DOES NOT check for *.2 files.. (2500 series date code '1C' and above all DO check for *.2 files).

You could also just hardware downgrade to a patched 3.55, dehash syscon and install 4.** cfw..

Either way would work.

Yeah, it was done before by the spanish DH team, JFW DH 3.56 MA could be installed on those specific PS3 that have 3.56 like factory firmware, using a hardware flasher of course !

I hope this will work on a 4.21 OFW CECHE01 PS3. On a sad note, if it does, that will take my fun of asking sabin for signed PUPs to annoy him.

You could unpkg the CORE_OS_PACKAGE.pkg in 4.21.1 REX and replace the ros0/1 in your NAND dump and flash it back.

Install 4.21.1 REX from XMB after that.

I read the topic thinking it meant that it was possible from the xbm to install cfw but I still need a flasher.

Look on the bright side you still need signed pups if you do not have a flasher.

With this method, do you have to be @ 3.56 or the console had to ship with 3.56? Im still on 3.55 kmeaw, just curious due to cyberskunks claim.
