Make sure your Playstation 3 is connected to the Internet via WiFi or Ethernet.
Then go in the [Settings]> [Network Update].
And simply follow the instructions on the screen.
Just under two months since the previous PlayStation 3 system software update has passed, and today Sony has released PS3 Firmware version 3.56.
According to VP of Network Operations Americas Eric Lempel via Sony's official blog on the update, to quote: "A new PS3 system software update, v3.56, will be released soon. This is a minor update that adds a security patch."
Needless to say, if you value PS3 homebrew, jailbreaking, downgrading or accessing PSN on a hacked PS3 it would probably be wise to hold off updating until PlayStation 3 developers can examine the 3.56 update.
As always, more details to come as they are available and below are some preliminary 3.56 Firmware examination details from PlayStation 3 developers via IRC:
KaKaRoTo: nice... it's full of spkg files now .. probably a new crypted pkg format
KaKaRoTo: possibly with a new signature that only ps3swu.self can read, but without the ecdsa fail
KaKaRoTo: humm.. seems I was misled, there's no spkg files in 3.56
KaKaRoTo: ok, so they added a new .self file in the PUP
KaKaRoTo: and it seems it contains a key that we don't know about
KaKaRoTo: yeah, probably a newer ps3swu.self that is more secure
KaKaRoTo: but they kept the old one for people upgrading from older firmwares
KaKaRoTo: the new ps3swu.self probably decrypts and uses the new self
KaKaRoTo: ok, so we need new keys for everything now
KaKaRoTo: I just pushed to ps3tools and ps3utils, fixes to allow pup/puppack/pupunpack to identify the new files in the pup

rms: try it.
KaKaRoTo: rms, what's that blob you pasted ?
adrianc: the new key
KaKaRoTo: ha, cool
KaKaRoTo: rms, if you know how and can extract all the new keys, please do and send them to me so I can upload to my ps3keys repo
adrianc: the new keys are all in there
rms: KaKaRoTo: i believe it's a lv2ldr key
rms: erk/riv/pub its all in one block
rms: i forgot the order its in though, it should be in that, its been a while
KaKaRoTo: I don't even know how you did to find those keys
adrianc: its in the data section of the elf usually
rms: its really simple
adrianc: after that look for references for blocks of data
rms: really KaKaRoTo, i think even you could do it
rms: adrianc: or something out of place
adrianc: helps to compare to older versions where you already know the key position
rms: and has a set of 8 00s
adrianc: KaKaRoTo 3.56 key works?
KaKaRoTo: adrianc, didn't try, not planning on trying atm
KaKaRoTo: not until I have ~/.ps3/ files prepared for me by someone
KaKaRoTo: lv2 3.56 decrypted
rms: keyset?
KaKaRoTo: pushing to github.com/kakaroto/ps3keys
KaKaRoTo: pushed
rms: ok
rms lv1 is also new
rms lv0 also
rms and also the spu stuff apparently
KaKaRoTo: humm.. I wonder who has the lv0 key
adrianc: i dont think lv0 is available
KaKaRoTo: iso keys are now pushed
KaKaRoTo: also, now, if we want to repackage things (unless they screwed up the ecdsa *again*), we'd have to change the keys in all the loaders... which means repackaging all the *ldr and iso selfs...
KaKaRoTo: so even more risk of bricking
KaKaRoTo: pushed spp keys
KaKaRoTo: the missing keys are for 'app', 'ldr' and 'rvk'
KaKaRoTo: btw.. where is that 'ldr' coming from ?
KaKaRoTo: and I can't figure out who decrypts lv0
KaKaRoTo: it can't be metldr since that one can't be changed
KaKaRoTo: and there's no lv0ldr
eussNL: bootldr decrypts lv0 afaik
KaKaRoTo: there's no bootldr either
adrianc: bootldr and lv0ldr arent in the pup
Matt_P: not part of coreos
Matt_P: and theres no such thing is lv0ldr
adrianc: apparently sony removed recovery mode
