Rebug CFW 4.21.1 On Virtually Any PS3 With Hardware Flasher

by ps3iso on November 7, 2012


Now this would be news of the century, but… In his post he explains the dire repercussions of this method. If something goes wrong you will have a permanently bricked PS3 console. So cue warning now. Dashhacks is not responsible should you try this method of downgrading your PS3. 

Further investigation also sheds some light regarding this method on PlayStation 3 models such as the 3k & 4k series. Reading over at ps3crunch developers Rogero & Cyberskunk have tested this and confirm the method not working on 3k models. In my search for further info, no confirmation regarding PS3′s with a base firmware above 3.56 have been confirmed working. I will post back once confirmation has been made.


A quote roughly translated by Google: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 (here and here or mirrored here). 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.

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


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 here and here) 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.
