    Sony PS3 Slim CECH-2000 System Flash Dumped!

    Sponsored Links
    Here is a little piece of news we skipped over when our PS3 Reference Tool arrived.

    One of our resident PS3 DEV's CouRieR extracted the flash of a PS3 Slim (CECH-2000) European console with Firmware 2.75 a few months back by removing the chip, and dumping it with an external reader along the lines of the [Register or Login to view links].

    The chip, a Samsung K8Q2815UQB, is a 128 Megabit flash chip. The dump, which weighs in at 16.0 MB (16,777,728 bytes), is quite similiar to that of a later model PS3 with the smaller flash.

    Earlier generation Fat PS3's, those that sported dual 1 Gigabit flashes, had two copies of the PS3 firmware along with a full AES filesystem (for /dev_flash) on the flash.

    The PS3 Slims, like later generation Fat's, have the AES filesystem (/dev_flash) on the Hard Disk Drive, and mounted virtually (like a loopback) with only one copy of the firmware.

    Both the Fat and Slim PS3 systems feature everything that one would expect: a bootloader, corresponding core operating system LV1/LV2 SELF's, along with corresponding isolated SPU code - all encrypted of course.

    Since everything is encrypted, and tied per box, the Slim's flash is really no different from that of a Fat PS3 - makes you really wonder what the "hardware differences" that made OtherOS incompatible were.

    Finally, for those who'd like to take a peek, here is the PlayStation 3 Slim's FileList Dump Log!

    Next week we will share some exciting PS3 Service Mode information, specifically on what we got in the mail a few days back! Then we will take a tour of the PS3 TOOL XMB as promised last week.

    Very cool news as always, especially considering the PS3 Slim console is the only version that Sony is making these days.

    That is awesome! That would be incredible if you can convert a slim to run other os...

    Wow, the flash is dumped... I thought Infectus could do that already? (I think not a complete dump - but I wasn't that keen to find out the truth).

    Just a thought... The HDD is already decrypted (somewhat)... could we use something along those lines to decrypt the Flash?! (maybe a unique key?).

    I know my questions sound dumb (probably are) but I have no idea of how the encryption system works (for now)!

    Alas no, on both the flash, and HDD, the flash filesystem itself is stored as an encrypted file essentially, so even decrypting the HDD will get you a still encrypted file (for the flash filesystem). Multiple layers of encryption - secure, just not good for us!

    Is there anyone who's bothered trying to decrypt these things for any period of time? I'd ask geohot to have a go, he doesn't seem to have a prob brute forcing... but he's a rude little... so ask nicely I would

    @cjpc

    Yes, indeed that is a problem. Maybe we should concentrate on the BD-DRive firmware. Any news on that front? I know the chip itself is BGA but still... someone with proper tools could do it right?

    I'm willing to help in wiring the whole chip to a reader if someone is willing to donate a fried board!
