FULL FLASH0 BACKUP W/ RECOVERY MODE
Today you will learn how to get the original .rcos from your Sony PSP using Recovery Mode. Yes, thats right, FULL flash0 backups. :)
Things You NEED:
1) PBP Unpacker
2) 2.50 Update, 3.03 Update or 3.10 Update or 3.30 Update or
3.40 update, or the 3.71 update, or 3.90 update.
3) RSPSAR Dumper
Use the EBOOT you need.
How To Get It Done!
Download the PBP Unpacker and open it up, then load the any of the eboots. After you have done that, place the files in a file where you can access it easily. I recommend a new folder on your desktop to store everything.
Recovery Mode Part...
Once thats done and done, activate Recovery Mode by holding R upon start up of your PSP system. Open up the EBOOT.PBP from the PSPFWDumper to ms0:/psp/game/recovery. If there happens to not be a folder there, create one. Get the DATA.PSAR from the eboot you have just unpacked and move it to the root of your memory stick. That is the top f your memory stick that has PSP and MP_ROOT. So, once you move it you should have:
Getting The Backup!
Once you got all that done *whew*, scroll down to "Run Program at /PSP/Game/Recovery/EBOOT.PBP". Then it will bring up a prompt that you would normally have to read. But in this case...press square. It will decompress the firmware to a "f0" file in your memory stick root.
Once you "Enable USB" you will now have a complete back-up of flash0.
