This is a big news to PS3 funs, especially to the guys who have a 3.55 system PS3, nearly a week ago , it is reported that  PS3 downgrade is available from 3.55 to 3.41 Firmware, and now , it became true, some guys have confirmed that PS3 3.55 to 3.41 Firmware Downgrader arrived today courtesy of solidpsycho through a guide from AmazingLarry.

You can download files here : Lv2diag_355 / PS3 3.55 Downgrade (3.41) / PS3 3.55 Downgrade (3.41) (Mirror)

Here is the  quote from them : Here is a patched 3.41 that allows you to downgrade. I patched the info0 to 356, and I also used Warrens method to bypass the br drive during the update. I have tested this on both of my PS3's and haven't run into any problems.

3.55 Downgrade has been confirmed on both FAT and SLIM consoles.

Please note you CANNOT use these files if you bought a PS3 that came stock with FW 3.50. DO NOT DO IT. STOP NOW.

THE SAME WARNINGS AND RULES APPLY:

You may want to download geo's 3.55-jb and install that and blackb0x ftp if you have not, it will be very useful for the next bit.

Blackb0x FTP server 1.2: Blackb0xFTP for 3.55 FW

If you have a fat PS3 with 256MB NAND you will need to back up your dev_flash folders, as you WILL LOSE BLURAY PLAYBACK. (on my FAT model i restored the DRL1 and DRL2 files in del_flash(2?) I did get to however keep all of my signed 3.55-jb homebrew, and it all works in retail mode except of course backup managers)

If you have a Small NAND SLIM or FAT console it would be a good idea to do one or both of the following:

In the XMB perform a system backup to save installed Homebrew you may have and gamesaves etc.. to an external device (i did this with my slim and it worked perfectly, all my installed signed homebrew from 3.55-jb works in retail 3.41 now)

-or-

make a COMPLETE backup of your HDD on your ps3 using ftp, although i dont think installed packages can be moved back over simply by ftp. i only tested the first method.

And now to downgrade:

You will need a downgrader dongle, search the forums for a DIY or buy one, or get an android/iphone, or an ipod nano, etc...

1) Unplug or switch off your console and then switch back on or plug back in.

2) While still OFF connect your Jailbreak/Downgrade device and press POWER then quickly Eject, you PS3 console should turn itself off automatically

3) OPTIONAL - Turn your PS3 on to verify you are in Service Mode (you will see a big red box, you can't miss it) then turn your PS3 back OFF

4) Place the lv2diag.self (FILE 1) from the archive and the PS3UPDAT.PUP (3.41 FW) from the archive on the root of a usb device and plug into the rightmost port on your console (dev_usb0)

5) Power on your PS3 with the usb device in and have a coffee, it can take a few moments for the PUP to install, your PS3 will turn off automatically

NOTE: if your system seems unresponsive and the light just stays green for ten minutes or more you need to use a different usb stick. i've had sporadic results with several different sticks.

6) Power your ps3 back on, you should still be in service mode, check your FW version now to verify you have downgraded successfully. Turn Off

7) Remove previous archive files from usb stick and now place lv2diag.self (FILE 2) on the root of your usb stick

8) Place usb stick in rightmost port of your PS3 (dev_usb0)

9) Turn PS3 back on with usb in place, it should turn itself off very shortly after.

10) Turn your PS3 back on and go through the configuration again.

All done!

You may think it is not a big update   PS3 dongle  improve,but it will make the gamer run more smoothly.

At first we should thanks to Maximu for compiling the r399 version of FBANext , because of his great job , it can be installed into a Jailbroken PS3 console!

Here's the quote from the Elotrolado forum (google translated,sorry ):

"The source I have it upgraded from google code on my laptop with the subversion client xD thanks anyway


Try if it works for Firmware 3.40 +


for people who have with firmwares backward sorry for them I could not compile it gives various error constants that is not even generate much less packaging elf pkg


I miss a change should put the name instead of 389 399 by editing the file version.h so there is no confusion that run version XD
