Place the file on the USB key in this way:KEY USB/PS3/UPDATE/PS3UPDAT.PUP

Turn on the ps3 in service mode:

How to get access to service mode

Now you can proceed to step 1.

STEP 1 Install CFW KMEAW
Once we have the PS3 on OFW 3.55. we can Install Kmeaw.
To do that: we need to place the downloaded file we got from DOWNLOAD 1
like this on the USB: /PS3/UPDATE/PS3UPDAT.PUP

Then we need to go to service mode:
How to get access to service mode

1. Make sure the PS3 is turned off,
2. Press and hold the power button on the PS3 it will power on then power off.
3. When it's off press and hold the power button again until you hear two consecutive beeps.
4. It will ask for the controller to be connected via the USB cable,
5. Turn on the controller and you will have access to the menu.

Insert the USB in the Extreme right USB slot
Select system update and follow the On-screen instructions.

Now we have CFW kmeaw installed.

STEP 2 INSTALL BACKUP MANAGER ENABLE (lv2.pkg) OMG OMG OMG Patcher

Place on the root of your USB Key the file lv2.pkg -> DOWNLOAD 2

Insert USB in the extreme right USB slot

Go to games> Install Package Files and select lv2.pkg

When the installation is complete.

Run the file OMG OMG OMG lv2 patcher

You will get a msg "Hello from Russia"

Press x to exit.

STEP 3 INSTALL Multiman MANAGER

PLACE on the root of your USB key the file that you got from DOWNLOAD 3 called
multiMAN ver 1.15.05 BASE [20110211_180000].pkg

Now,

Go to games > Install Package Files and select multiMAN ver 1.15.05 BASE [20110211_180000].pkg

When the installation is complete.

Run Multiman manager.

STEP 4 BACK UP A GAME
TWO choices:
You can backup a game to your internal hard drive
Or you can use an external hard disk

Lets begin by internal hard drive:
Insert A Blu ray disk
Click on copy game and then click YES.
Wait for the backup to complete (IT TAKES TIME ... )
Click X when prompted to do so

You will return to the main screen of Multiman manager:
Remove your blu ray disk so you can see only the backed up game files
Click load game
You will return to the XMB
Insert any other blu ray game
It will load as the game you backed up
Click ON Disk icon
Enjoy!

External HARD drive
You will need to format your hard drive to FAT32 (otherwise it will not work)
PLUG in hard drive to extreme right USB slot
Insert A Blu ray disk
Click on copy game and then click NO.
THEN CLICK YES
Wait for the backup to complete (IT TAKES TIME ... )
Click X when prompted to do so

You will return to the main screen of Multiman manager:
Remove your blu ray disk so you can see only the backed up game files
Click load game
You will return to the XMB
Insert any other blu ray game
It will load as the game you backed up
Click ON Disk icon
Enjoy!
EXTERNAL HARD DISK NOTE:
The fat32 system does not allow files more than 4gb to be written on it.
So while backing up to an external hard disk Multiman manager will split files larger than 4gb to files that are 4 gb of size.
So if it happens to a game you cannot load it Directly from the external hard disk.
It will give you an error message "cannot load cut files" <- don't really remember the message.
So what you need to do is copy back the game from the external hard drive to the internal using Multiman.
DO NOT RE-BACK UP the game on the internal hard drive.

REPEAT FOR MORE GAMES.

NOTE
-More Backup managers are coming out everyday. Like Rogero who has stealth ID.
- It is now impossible to login to PSN using with a jailbroken PS3
- Going from CFW to OFW is possible but there will always be traces on the ps3, showing that this ps3 was jailbroken.
- Peace.
