If you always want to be on the latest (and not particularly greatest) firmware version on your PlayStation 3, then Team REBUG has you covered as they’ve just released Rebug 4.86.1 LITE which is based on OFW 4.86. Team REBUG offers some of the most popular CFWs for CFW-capable PlayStation 3 consoles (i.e. minFW of 3.56 or below) which come with a good deal of features including the ability to toggle the QA flag, boot into OtherOS, the Rebug Toolbox, a Package Manager and more.
As per its change log, which is in the link below, Rebug 4.86.1 LITE comes with:

  • An OFW 4.86 base
  • Rebug Toolbox 2.03.04 which comes with support for 16 languages
  • Improved Stability which undoubtedly stems from the rock-solid OFW 4.86

You may grab Rebug 4.86.1 LITE for your PlayStation 3 from links found at the bottom of its release post on the official Rebug website. The team’s currently looking for someone to provide a DEX OFW PUP for REX/D-REX release in the future – the latest REX release is Rebug 4.84.2.
