Consumers and organizations that currently use the “Other OS” feature can choose not to upgrade their PS3 systems, although the following features will no longer be available;
Ability to sign in to PlayStation Network and use network features that require signing in to PlayStation Network, such as online features of PS3 games and chat
Playback of PS3 software titles or Blu-ray Disc videos that require PS3 system software version 3.21 or later
Playback of copyright-protected videos that are stored on a media server (when DTCP-IP is enabled under Settings)
Use of new features and improvements that are available on PS3 system software 3.21 or later
For those PS3 users who are currently using the “Other OS” feature but choose to install the system software update, to avoid data loss they first need to back-up any data stored within the hard drive partition used by the “Other OS,” as they will not be able to access that data following the update.
Notorious XorLoser has fully rewritten GeoHot’s PS3 glitch attack programs, that allow more convenient exploiting. He names it XorHack.
It allows you to call lv1 syscalls (level 1 system calls) from a normal (userspace) program. It also lets you run the software required when triggering the PS3 exploit from a normal userspace program. To give an example of how it can be used I have included the following example programs:
ps3exploit – Runs the software required to exploit the ps3, it loops a number of times which can be specified as a parameter. (This still must be used along with the “button pressing”, it will not exploit the PS3 via software alone).
dumphv – Dumps the hypervisor to a file in the current directory.
dumpbl – Dumps the bootloader to a file in the current directory.
dumprom – Dumps the system rom to a file in the current directory.
