    and heres one for JSD 100 You must login or register to view this content.

    I haven't actually downgraded with this method but it should work(im ordering a teensy soon).
    ME Coding i currently have 3 ps3 i will be ordering a refurbished fat from game stop to try because it allows downgrading Happy

    Tutriol and confirmed by moderator of ps3hax his quote on the subject:
    Pockets69:i would like to tell that this does work, firstly because eussNL said so, and probably has one installed on his machine, and secondly because defyboy has one installed in his machine
    now if doesn't work one of two things have happened bad wiring, or hashes were not disabled on the .pup with this being said, it works.

    PS3 Prodigy;3617951]Just a few things i know that you might want to add to your TUT. When you open your Flash.bin (Dump) in hex editor the Core_OS you need to replace starts at 6F FF E0 in the offset C0000 and when re flashing make sure you only swapped the Core_OS and not the EID,METLDR,BOOTLOADER,VTRM because if you do your Ps3 will be permanently ****ED and you can't just use any 3.55 Core_OS you need to patch the hash checks before you use it.

    PS3 Prodigy;3620267]Phantom i not trying to troll or flame because your right every NOR flash is unique to it's conslole but Coding added my quote where I stated you only swap the Core_OS and you don't swap the EID,METLDR,BOOTLOADER,VTRM which is the only thing that makes the flash unique to your console so his TUT is correct





    TUTRIOL:
    1. Dump your ps3's NOR

    2. Make sure you have a clean NOR dump.

    3. Open your NOR dump in hex editor

    4. search for 6F FF E0 in the offset C0000 and delete the next 7,340,000 bytes( this will delete the whole Core_OS)

    5. Take a lower firmware Core_OS and patch the hash checks.

    6. Copy the new patched Core_OS into your NOR dump

    7. Flash it back to your console.

    Here where you can buy a teensly it $24 Happy cheapest compare to $80 infectus $65 prog
    My review on the item is buy it. It cheap and gets you what you need to do.

    Yes your NOR Flash.bin you get from dumping needs to be 16.777.216 Bytes no matter what it has to be that size and also if you gonna dump from a bricked console your going to have to be quick to actually start the dumping process and hope your computer detects teensy and is able to take control of the NOR Tristate before your console shuts off if you want to have a useable NOR dump.

    For the soldering part of the TuT your going to need to know your Ps3 motherboard revision and your also going to need:

    - solder point diagram for your motherboard ( you can find those diagrams You must login or register to view this content.)

    - a soldering iron (pointed tip works best)

    - some silver bearing rosin core solder

    - solder flux

    - 30 AWG kynar wire or a PC IDE cable
