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

    Compatibility:

        Any PS3 already running a CEX custom firmware

    Features:

Made from 4.86 OFW (CEX)
All the features of the 4.86 OFW (CEX)
