From afiser on the PS3 Keys posted above: This is as simple as putting the bootldr keys (what you all call the lv0 keys released last week) in the scetool data/keys file and running scetool.exe -d lv0 lv0.elf

From zadow28: Found some interesting, when debugging lv1.elf from 4.31:

Only shows when debugging.. well thats where i'm at so far regards.

Dumps/Debug off core_os/Devflash files. 4.++

Have done some experimenting. Found out that you can actuelly run the self/sprx (ppc)

From core_os, and Devflash.. from "official" debugger,and dump them. You have to set up an fake Param.sfo, so the debugger thinks its an executable.. but the result is quite amazing. You really get an better overview, since you can see al the files it communicates with.

I use Ida pro 64 PPC proccesser to analyze, the dump. Then use Kakarotos scrips analyze_sprx.idc. Set new TOC, when the script tell you and reanalyze.

The dump is 4mb packed but 250 mb unpacked. I'll give an more deeper, TUT when i have the time. Works on all files so far i tested PPC ones, so all expect the spu files. Tested vsh.self/mcore.self/psp_emu.self plus many more.

Well here is the dump, for BDVD.SELF: http://rghost.net/41639087

Off course you can debug all the files, and the embedded spu before dumping.

Finally, from Team Siracide comes PS3 DEV_Flash 4.31 with details below, as follows:

From that forum, it isn't actually useless if you thought so and play MHP 3rd HD

"If you've had issues with Monster Hunter Portable 3rd HD, download the optional PS3 software update (v.4.31)"

[pinoytechno]

sony was aware about the new cfw 4.30 hehehhe ps3 scene rocks

[SwordOfWar]

This is unlikely related to the recent CFW.

If they release an update related to blocking CFW, you can be sure it will be a mandatory update.

[PS3 News]

Indeed, and from what I read because this isn't mandatory at this time the PSN passphrase won't likely be changed/updated for it either.

sony suck. now sony vs hacker as cat vs mice. ha ha. this isn't mandatory they lie at all. if you dont update you can't play PSN. that's it

[PS3 News]

PS3 Firmware 4.31 is now live, and I have added the download links to the main article also for those who wish to examine it!

[PS3GAMER20111]

I think Sony is just showing that how insecure they are now. lol

[DeviDVS]

I can't find update 4.31 on Sony's site?

[PS3 News]

They usually update it there the following day, even though the PS3 updates hit PlayStation 3 consoles the night before.

We get our updates from Sony's PS3 Updater List links directly:
