133w ago - Today PlayStation 3 hacker Cyberskunk has released a Rebug PS3 CFW Boot OtherOS++ and OtherOS Prep Tool for Linux fans alongside a Rebug 3.41.2 & 3.55.1 Custom Firmware (which allows PSN access using this guide via SP-INT) and details on how to add OtherOS++ support.
From their page: Boot OtherOS++ does what it says. One click easy. OtherOS Prep Tool is used to prepare your system vflash and install petitboot ready to install Linux. IT DOES NOT INSTALL LINUX. For tutorials and videos on how to install Linux head over to gitbrew.org.
OtherOS Prep Tool is based off of graf_chokolo’s and glevand’s source and is a one or two step solution to getting petitboot up and running and on your way to installing Linux on to USB or PS3 Hard Disk. At the moment it only supports 3.55 but we will add support for lower firmware soon.
16MB NOR PS3 (Model CECHH or Higher)
3.55 OtherOS++ enabled firmware installed
(If you want to use REBUG 3.55.1 grab PS3MFW Builder 0.2 Portable from here with the tasks pre-selected to add OtherOS++ support)
