Video: PS3 4.31 OFW to 4.30 Rogero v2.03 CFW with Flasher Guide


Sponsored Links
90w 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.

Files needed for safety and to proceed:

E3 back-up checks links:


Steps:

  • 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.

after you finish the downgrade and out of factory mode you are safe to remove the flasher, the best update.bin i know of its the samsung one that allows you to do this on more than one console. that is the update i have available in the links.

did more research do not get a new or near new slim as it will not be compatible with downgrading in general at this time. nothing its set to edit a metldr 2 and the metldr B1 version. newest versions of 2500x older ones can, + 3000x + 4000x are not downgrade able since their metldr's are not fixed yet to be down-gradable.

i'm guessing all slims and new slims can have a backup created and a write with the original back up but it can not be modified due to metldr 2 which has not been cracked to allow downgrade.

Ok, do you leave the flasher in the ps3 and the ps3 hdd in that enclosure or when all is done you remove the flasher and put ps3 hdd back in, are you able to reuse the flasher on other ps3s? I personally have 4 ps3's

open your nor backup in a hex editor and paste the ros and revoke patches below from the wiki. then put all switches down on the flasher and press start.

ROS1 [Register or Login to view links] patch2 (7 MB) 0x7C0010 0x6FFFE0 same as patch1?

trvk_prg0 (0x40000)
trvk_prg1 (0x60000)
trvk_pkg0 (0x80000)
trvk_pkg1 (0xA0000)
rvk-040000 [Register or Login to view links] (512 KB) 0x40000 0x80000 one big patch overlapping several revoke area's

the patch looks like this:

alright it is confirmed that 3000x models are not able to be successfully downgraded to 4.30cfw. anything older is able to with this method, but i have found a way to modify the back up and still be able to install it instead of letting it do all the work. just does any one know how to modify a back up to allow downgrading with out the unlock mod of the e3 doing it for you?

you will need to solder tristate point its the same as the 2501 models since i just bricked my 30001 for fun and fixed it. if any one wants a copy of the original backup that is safe on my 3001 let me know.

yes i did cause i tried a rogero auto patch fixer on the back up for fun that is set to downgrade but its fixed now and you are correct about 3000 models but this still allows downgrade to 4.30cfw for older slims. i only knew that firmware was 3000 models. and i thought there was a way to have 3001 models on 3.55 but could not dual boot because of it?
