PS3 CFW 4.86 Dual-Boot (DB) Littlebalup's firmware released

Developer @littlebalup has released a 4.86 Dualboot Firmware. This firmware only of use for current PS3 Custom Firmware user's was an idea originally crafted by @habib several years ago.


The Dualboot (DB) firmware is nothing else but an Official Firmware (OFW) . The ONLY difference is that you can RETURN and INSTALL a (4.86) CFW directly (without having to run an exploit again). So this is only useful for those existing CFW user's. To review, basically you install this PUP when you want to be official (for doing things like using PSN) and then re-install your CFW PUP when you want your custom firmware abilities back, such as launching homebrew. Additional details about this firmware can be seen below in the release notes provided by littlebalup

        Any PS3 already running a CEX custom firmware

  • Made from 4.86 OFW (CEX)
  • All the features of the 4.86 OFW (CEX)
  • Same CoreOS files size and structure than OFW        Same PUP size and structure than OFW
  • Patched isoldr and spu_pkg_rvk_verifier to allow installation of any 4.86 or higher CFW (CEX)

  •  Rename the "DB_4.86_littlebalup.PS3UPDAT.PUP" file as "PS3UPDAT.PUP"
  • On a FAT32 formatted USB storage device, create a folder named "PS3". Within that PS3 folder, create another folder named "UPDATE".
  • Copy the "PS3UPDAT.PUP" file to the UPDATE folder you just created.
  •  Verify the MD5 signature of the "PS3UPDAT.PUP" file you just copied in the UPDATE folder.
  •  Plug the USB storage device to your PS3 then install via [Settings] -> [System Update] -> [Update via Storage Media]
  • Follow the on screen instructions.
