21w ago - Nearly two months after the previous update, today I have posted a guide and video on how to downgrade a PS3 4.31 OFW console (including CECH-300x slims) to 4.30 Rogero v2.03 CFW using a PS3 Hardware Flasher with no 3.55 needed.
Very easy tutorial. Follow the steps to downgrade a PS3, but when you get to the first step of the USB downgrading part after putting your PS3 into service mode, use Rogero 4.30 CFW v2.03 on the root of the USB with the lv2diag.self to downgrade instead of the 3.55.
So again, no 3.55 ever touches the PS3 during this whole setup! Doing this will also now allow CECH-300x models original slims to be downgraded to 4.30 CFW as long as it never touches 3.55
The whole reason for this was to find out if the E3 fits a CECH-400xx model super slim models, but all I needed was proof that you can downgrade from 4.31 to 4.30 CFW with a flasher.
So if any one out there has an E3 and a new super slim model please test this if it works! You can make back ups of the NOR incase it fails.
Here is proof you can but I still do not know if the CECH-400xx models are compatible since I do not have one.
Step 1 - switch pup's with Rogero's 4.30 CFW v2.03 - my link has it set ready
Step 2 - lv2diag out of factory mode
PS3 nor dump patcher to fix bad back-ups
downgrade.bin - makes it rewrite the nor to allow factory mode access
update.bin - its the Samsung version of the flasher firmware, allows multi-console downgrades.. more than one console in other words
PS3 Flowrebuilder - decrypts the backups to look and make sure its good
Here is proof of me downgrading to 4.30 CFW no 3.55! My video is not cut but speeds up through the middle since it takes almost 2 hours to prove this. You see every time I drop the camera, fix the E3 and finish the downgrade straight to 4.30 CFW Rogero v2.03 which you will know it's spoofed to 4.31, you can see the install PKG / lastGAME icon after downgrading.
Hint: The E3 always has the ribbon starting under the NOR words (pictured below).
Always test your back ups and even use Flowrebuilder 4.2.2 to reverse decrypt to make sure your back up was good.

Which reads: Install a CFW 4.21 on PS3 any possible!
So yeah, they both state "any" and the one mentions "including metldr2" so that is why our headline also includes "any" in it.
Also those files I can't download, idiotic letitbit site blocks US and proxies and the other is no better saying "file not found" here... can someone mirror the file patch.rar [13.39 Mb] for us please?
Following up on the PS3 Factory 3.56 with Flasher news, French PlayStation 3 developer raymanvtwo has shared a way to install Rebug PS3 CFW 4.21.1 on any version PS3, however, it requires a PS3 Hardware Flasher, will format your HDD and may result in a permanently bricked console so be WARNED!
Below is a rough translation of the process, as follows: You will need just a flash, great care, attention and rigor.
This method will format the hard drive of your PS3, make sure to recover your important data. Also, you incur a risk of irreversible brick in case of bad handling. Neither I nor PS3-Addict can not be held responsible. If you are not able to follow this tutorial to the letter, thank you spend your way!
Firstly, ensure the validity of your dump, flow rebuilder is the best in the field. Also check that all your fichiez is a different size of 0 bytes (including bootloader_0). If there is a problem, it will help you out.
Now that you have your dump, to see if the offset 200 if you or IFI FI.I with HxD as hexadecimal editor. If you IFI, go to the next step. If you FI.I, open flow rebuilder Select "Byte reverse and extract a NOR dump file." and then made your dump "execute operation". If you get an error is that your dump is not good. Before you dump, you must make new bytes reversed under penalty brick your PS3 but it will be easily retrievable.
Now, you need winskeet and patch (http://letitbit.net/download/08985.06dbbb4e087cb1d6bfd58ef64bae/patch.rar.html and http://vip-file.com/downloadlib/22390657927256830-08985.06dbbb4e087cb1d6bfd58ef64bae/patch.rar.html or mirrored http://www.sendspace.com/file/1t0s6u). Winskeet open, go to the tab "patch" in "input file", select your dump file and select the patch. Txt file previously downloaded the archive. Made apply and save your dump patched.
Now write your dump patched (do not forget to do it again if you had reversed bytes FI.I at the top). Now your PS3 Decomposition Systems is no longer able to work, do not worry, this is normal. Go to the recovery menu (it may be that your PS3 shuts herself at the first attempt, the second should succeed). Install CFW Rebug 4.21.1 (available via the "system update").
If after several attempts you are unable to install Rebug CFW 4.21.1, format the HDD, then reinstall the switch on the PS3. On a USB drive to FAT32, put the. Rebug 4.21.1 CFW PUP (available http://letitbit.net/download/35342.30c0ea93c1ba764e52ea4e6cd5cf/REBUG_4.21.1_REX_PS3UPDAT.PUP.html and http://vip-file.com/downloadlib/4257064879591588075374-35342.30c0ea93c1ba764e52ea4e6cd5cf/REBUG_4.21.1_REX_PS3UPDAT.PUP.html) in x: \ PS3 \ update and rename it to PS3UPDAT.PUP. You will get a message asking to connect a controller and press the PS button, then follow the plug your USB drive, make sure there is no disc in the drive BR, then press START and SELECT at the same time for 3s and follow the instructions to install your CFW. Enjoy.
PS: This method has been tested with the Rebug CFW 4.21.1, if you use another CFW, it will be at your own risk. This method has been tested on a PS3 with the metldr "anti CFW 3.55", it should work on any console. Thank you to give me a feedback on the effectiveness of this method and possible problem. Thank you also include PS-addict and I and keep the links given in this tutorial if you publish on your sites this method.
Finally, thank you to the work of the "Three Musketeers" and the Rebug team has allowed me to patch my PS3.
From Cyberskunk: Tested on my 3K series.. DOES NOT WORK (didn't think it would)..
From Rogero: Tested here also on a 3K machine, didn't work, it bricked... metldr .2 and lv0.2 won't be easy to bypass....
