Hello
Was able to successfully downgrade my cech2501a with e3 flasher.
Also, made sure I backed up my bios..I have the 3 copies
Skipped the Re-hashing in BaileyScream toturial under "Simple Downgrade.."
http://www.ps3hax.net/showthread.php...785#post387785
I went from CFW rogero3.70> CFW rogero 4.21> then CFW 3.55 to use the cobra that I recently bought.
I removed the E3 flasher at this point
Once everything was put back into ps3...the power/light never came on
I took everything apart and put it all back....still nothing no light no power
Inserted E3 flasher again.....still nothing
Any ideas???? Do i have to solder to have power???
Thanks guys

ok now im worried cause i have the same model and i am getting my E3 flasher and my E3 card reader for x-mas and i dont know if i wanna downgrade now

[guardianAnge7]

I am assuming you have to remove the e3 flasher before putting the ps3 on service factory mode or after downgrade..the 000001 switches.
Or maybe just because of me experimenting with different CFW.
It worked before I removed the e3 flasher.
Follow directions and be sure you know what you're doing and take your time buddy.
I was very doubtful on the voyage from 4.25>3.55cfw using the e3 flasher
But, I pulled it off with this model. good luck

Did you connected all the cables ( like power brick cable )?

Did you check for any shorts on the motherboard ?

And, try removing the dvd drive from the motherboard

[mattg99999]

this is what the tut says after u downgrade


remove the E3 Flasher and re-build your ps3 (if your doing the dual boot then just unplug the clip fron the flasher rebuild the ps3 then reconect the E3 Flasher to the clip inside the hdd port)

re-insert the hdd then connect the ps3 to a TV the usual way
(if your doing the dual boot then connect the Esata stand and put your first hdd in that)


turn on your ps3 and you should have this on screen

Turn the ps3 back off insert your dev usb board (programmed with the correct files) into the right usb slot.

a full list of boards are listed at the start of the thread in the second tab down called
"Wrong you need these tools before you even think about following a guide"
inside that tab you will see the second tab down called "A development board" in there is lists of the different dev boards.


Unplug the ps3 from the mains. Wait a few seconds then plug it back in.

Turn the ps3 back on then immediately press eject within ~200ms. Your console will turn on and if your dev usb has led's then the dongle will light up the red LED followed by the green LED and turn back off.


After triggering Factory Service Mode, go to the folder called “service mode files” & in there is a folder called “service mode 3.55 downgrade files” put the contents of that folder into your usb stick and plug it in the PS3's right most USB port (remove the dev usb & put your usb memory stick in its place)
(the files are rogero cfw v3.2 and the normal Lv2diag.self (365.5 KB) 3.55 get in FSM )

Turn PS3 on, it will install the firmware you had put there (even though you have no screen output, you can see it is busy by looking at the activity led of the hard drive and of your USB Mass Storage Device).

if you get the flashing green power light then this is due to the firmware not installing. first check your hdd is plugged in properly. this is usually what I forget to do. if it still flashes remove your usb stick put it in your pc and you will see “UPDATER_LOG” as a notepad file upload this to a file share site copy the link and CLICK HERE to enter the chat room. create your nic name press enter then click the green word "#ps3downgrade" to enter the correct room.
paste your link with “can someone please check my updater log. I have followed the guide here (this guide) I cannot get rogero cfw to install in service mode.


PS3 will turn itself back off when it has finished installing the f/w (Nb this does take a while.
So go make a cuppa or have a cig).


Now remove your usb stick put it in your pc and you will see “UPDATER_LOG” as a notepad file open it & look through it to see if it contains errors (if it does upload the log to your file share account and ask for help online on IRC) (it should say at the bottom “0x83manufacturing updating SUCCESS(0x8002f000)”)

Now you need to get the ps3 out of service mode.

Open the folder “service mode files” and inside you will see a folder called “get out of service mode” copy the file inside to your usb stick. Put the usb stick back into your ps3 it will boot then the hdd light will flash then turn off. Remove the usb stick. (the file is Lv2diag.self (201.42 KB) get out FSM)


turn on your ps3 and it should now boot to this screen follow the on screen instructions

so u do gotta remove the E3 flasher before the service mode

now im not saying thats y it happened

I left my E3 in throughout the downgrade including while I dehashed, put OFW 3.55 on and made a valid OFW 3.55 dump. Only after that did I remove it.

Do you not get even the red standby light? If so, something may not be connected.
Another possibility is the PSU's 5V has failed or worse case is damage occurred to the motherboard.

what should i do to take extra procaution so it dont happen to me should i put another fan on my ps3 so it donts get hot while im doing that downgrade or what

[guardianAnge7]

@ MJ999
Yeah double checked all the cables are connected and still no juice. I removed the dvd and power supply. Also, checked the CMOS battery.

@ redtree
No red stanby light....I plug in the power cord and no lights.
I'm gonna try a different PSU when I get the chance.

@ mattg99999
HMMM I don't think a fan will be necessary for the dwngrade. But, if you want the security..then just place one near by...so you wont sweat into the motherboard while putting the E3 flasher...Cause trust me I was sweating it, but made sure to wipe off my face so it wont drip into the open PS3.

Then most probably, something maybe shorting the ps3, Strip the ps3 and just try it with just the mobo ( no heatsink ... Just the mobo and power supply ) and try it.

If that doesn't work, the power brick is dead ( u tried changing the power Outlet cable ?? )
