Following his previous release, today PlayStation 3 developer playerkp420 updated his Dual Boot OFW 4.81 for accessing PSN a bit safer on modified PlayStation 3 consoles.

Here is what's new from @playerkp420: Playerkp420 Dual Boot OFW 4.81

I whipped up a DB OFW 4.81 to share.
  • Made from OFW 4.81.
  • ECDSA check patch applied to isoldr in lv0.
  • ECDSA check patch applied to spu_pkg_rvk_verifier.
  • Same metadata applied to keep the exact same size as OFW. (see pic below) Even all the encrypted files inside CoreOS are the same size.
  • Can be installed over OFW 3.55 and any CFW with a lower or same version.
  • While on this DB OFW 4.80, you can install any CFW with the same or higher Syscon version.
  • Can only play disc based games and games downloaded from PSN. (Basically it is just like OFW, except you are able to go back to CFW without a hardware flasher.)
nNCNYHe.pngFor those that don't know, this is for a safer way to play on PSN. It is suggested to have 2 hard drives. One for CFW, and one for this DB OFW. When you want to act like your PS3 is not jailbroken, insert DB OFW HDD and install Playerkp420 DB OFW 4.81. Then you can play as you are on OFW.

I personally tested this on my CECH-2501A, and my CECHA01. On both I went from Darknet 4.81 v1.00 to Playerkp420 DB OFW 4.81. Then back to Darknet 4.81 v1.00.

It is recommended anyway to boot to recovery menu after switching HDDs and installing either DB OFW or CFW with Option 6 every time you want to switch.

:alert: Don't just switch HDDs, because then your NOR/NAND Flash will still have CFW and you will risk ban from PSN.

Can i have two hard disks , one with 4.81 DB and one with 4.81 Cobra ? Will i need to reinstall when switching HDDs ? What are the games with a high ban risk ?
Don't use dual boot OFW.

Nah you don't get banned play to game non modded and modded. You need to install webMAN MOD then first loaded for game ready, clean history and CFW Syscall disabled, you can login PSN and play game modded or non modded have fun, never ban risk. Sony is hard c4rt00n anywhere no found for you.
According to Sony's Page on the 8002F165 PS3 Error Code:

The PS3 system is encountering an issue when trying to update the system software.

Restart the PS3 system, then download and reinstall the update.

And from the wiki 0x8002F165 is an Update error - Error with installing Firmware update. Make sure the sourcedrive with the PUP is readable and reboot the system first.
Are you trying to install this CFW on an OFW PS3?

If you let me know your PS3 model number and which Firmware version it's currently on that may help troubleshoot further. ;)
