STILL NEED VALID CONFIRMATION FROM MANY SUCCESS
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:
- 4.31 to 4.30 e3flasher.7z (235.40 MB)
PS3 USB links after NOR editing:
- 4.31 to 4.30 e3flasher.7z (194.60 MB)
- 4.31 to 4.30 e3flasher.7z (194.60 MB)
E3 back-up checks links:
- back up check and patch.7z (5.56 MB)
- back up check and patch.7z (5.56 MB)
- back up check and patch.7z (5.56 MB)
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.
Response from anonymous master via google translation:
Here I just explain as best I can, and no mean judge the work of others.
RUMOR about CECH-3xxxx could CFW, circulating today:
1. VERY highly unlikely and very simply by using PATCH NOR / NOR bin Modification else to use "Lv2Diag.self" base ... 3:55 (100% we can access FSM FW 360 + + ..... but once again only No CFW for the repair, such as: Bluetooth / Blueray drive is broken, so we can access the FSM to continue the firmware update that failed, and I have proved that in the case of engine failure 3xxxx).
2. And highly unlikely, if CFW common nowadays that can be installed into the engine CECH-3xxxx, because .... well too much explanation ..
Conclusions about the RUMOR at this time, .....
He (who issued the rumors on the web outside) too quickly interpret that could directly DOWNGADE 4:31 to 4:30 without having to go through the process to 3:55 according to him in a way that can be done to the engine 3xxxx ...... NO WAY.
It is true, "DOWNGADE 4:31 to 4:30 could directly without having to go through the process to 3:55" and it had me run out of the time machine date code 1B, and I use his CFW JFW-DH key base of 356.
To Downgrade important key issues on file Core_OS_package.pkg of all CFW 4xx, and from it you can make the file Patch NOR / downgrader, and after the patch you wrote to your next NOR immediately wrote 4xx install CFW's simple ..... . so without having to go through the process of FSM or 3:55.
CFW whatever his rebug rogero-GIFTS-E3-even though
We must understand the system firmware so that we can modify the files in it, in order to access a restricted area, which is considered a loophole by sony.
