127w 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:


PS3 USB links after NOR editing:


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.

God why are you trying so hard...

if this is possible then probably flashing back to OFW 3.55 (or less) just to then go onto a CFW would be a better option...

Gives good feedback on successes to date and failures... seems a bit hit and miss but a 3k KTE001 has had CFW Rebug 4.21 installed and running games isos from Multiman (crisebetes is the dudes name who got it running on the 3k)... seems legit.

For those who have tried... you can expect a dead console for first few tries... formatting the hard drive seems to be key part for update to take.

i'm happy with my ps3 now anyway, all the trouble of switching to dex and reverting to cex wasnt totally pointless. thanks to me now already having the 2 flash files required to get full use out of rebug rex all those that didn't make the dex switch cant use these features untill they go and make those files.

i'm even considering updating my other ps3 to normal ofw just so i can get a psn account and make use of all the freebies on offer.
i still wont connect a cfw ps3 to sony servers , not after seing multiman show up in somones recently played games list.

obviously sony can spot that too.

cause up to firmware 3.55 sony used a constant number to generate their console private keys which meant that we could calcualate them also, this was changed in 3.56 they now use a true random number instead of 4. i learned that from this video:




which is excellent by the way and well worth watching, its one of my youtube favorites

then again, i'm still waiting in the hope someone works out how to resign pups as 4.30 , and so they can just install as though official.

since all the LV0 and other keys are known , i cant understand why if homebrew can be resigned as 4.30 why not a 4.25 pup be patched and then resigned as 4.30, obviously no use to people on ofw 4.30 but would be usefull to anyone on anything lower.

but i'm a noob. lol, just as i asked, technodon already answered, lmao, talk about timing.

sorry, i think i maybe patched the wrong ros area so i dont think that this does work.. maybe some consoles do but i doubt that

i was chatting with euss and other devs on irc a couple of days ago and these consoles were apparently signed with a new bootloader private key, after sony fixed the random signfail bug that the fail0verflow team found in 3.55 so we cant use the new found lv0 private key.
