Here's a brief summary of the steps involved; dump the NOR flash using a hardware flasher (Eg. NORway on Teensy++ 2.0, Progskeet or Infectus), modify the dump to enable factory service mode, write the modified binary back to NOR flash, downgrade to CFW v3.55 kmeaw."[/p]

    Ahh. good that the ps3 scene is still alive. [​IMG]

    but this method is not noob-friendly, so.. wont be much use to most of the community.

    I wonder if they dropped this just to screw with sony.

    Sony:"ps3 now 50 dollars cheaper"!

    Hackers:"ps3 hack incoming, get your systems while you can"!!

    Hm. Will this work on a bricked 3.56 (By this I mean the PS3's inability to read HDDs)? Or will I have to have a working PS3 that can get into the XMB?

    Hmm..interesting... I'm still curious as to why you would need a beer, though.

    It's pretty hard to do the rest of the process without the beer. Ever used a soldering iron?

    Obviously you need a soldering iron of exceptional quality (trust me, those pesky solderings for the NOR are hell to newbies) and a really steady hand.

    You also need an Infectus/Teensy++ or some other way to dump the NOR.

    Here's a nice pic. And this is just the Teensy++ part.
    Warning: Spoilers inside!

    The NOR solder points are EVEN worse.

    Remember, you have to be HIGHLY skilled to do this. Otherwise you're 100% certain of killing your PS3 in the process.

    There's a good es-en translation on PS3hax.net : http://www.ps3hax.net/2011/08/downgrade-fo...-firmware-3-70/
    (they just need to fix a link, check the elotrolado source if you want the modified lv2diag to disable bluray. Attention, don't use LV2diag on unmodified NOR, you can't exit service mode on 3.56+).


    If it's becoming more popular, like being the only method to hack the PS3 past 3.55, I guess there will be solderless modchips.
    There's already a project for the Progskeet solderless, you still need to solder the programmer chipset to the "chipset hat", but it's far less complicated.
    It will certainly become a real no solder if there are high demands.

    If there was going to be a post to induce a *twitch* this would probably do it.
    It might look complicated but someone well versed in soldering could pull that off easily enough (personally I would fire up the hot air station). Just for reference you can buy a teensy with header pins on it and although I am not 100% certain most of those solder points look like pads or vias- no trace or pin soldering.
    Wii stuff- I am kind of shocked hardware methods did not take off there (a quick scan of the stuff done in that world says it would be quite easy).
    As for Sony- a company attempting to protect their devices... say it ain't so.


    Anyhow great news. I am not sure I want to "sacrifice" my teensy for that (although to be fair I am using mine mainly as a toy) but it is good to know it can be done.

    Also, I would like to add that hacking became popular only this generation with DS and Wii, because it's sooo easy.
    Buy a flashcard, done.
    connect HDD to Wii, done.
    People of every age are doing it (I know 5-7 years old kids, and 80+ years old gramps using flashcards).

    Old console's hack needed modchips, PS2 has something like 15~20 wires, etc.
    now hackers try to make it easier, like swap magic, Mcboot, etc. but few years ago it was only the "hard way".
    PS3 is just back to sources.

    the guys here are temp are fast... i just read yest that the info will be posted soon and wow its here today
    they were stressing on using the progskeet and hopefully even the new so-called unhackable ps3 will be hackable with this hardware

    i still wish to wait for a software method for downgrade over any hardware one thats because ppl charge 100$ for softmod on ps3 (hardly anyone knows about it here) so u can imagine the hardware mod cost

    I am not sure about this, I saw a while back a way to unbrick ps3's but, I am not sure if this will work with that method. Might try connecting to irc and asking.

    There's is no point of my hacking my PS3 unless I can play online with it without me getting ban or some ish. Though if I can reverse this I MAY give it a shot
