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.

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.

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.

Infectus or Progskeet are your only choices for a NAND based console.Dancing

Can you proof that or are you just bullshitting?

Because according to the developer of NORWay, the software used to flash with Teensy++:

Originally posted by another user
Samsung flash memory is currently not supported by NORway. You should be able to dump your flash, but writing is definitely not supported. I've never checked the Samsung datasheet before, but Samsung NOR is organized a bit differently (284 blocks vs. 128 sectors). I'll add support for Samsung eventually, but cannot yet tell when. Sorry for any trouble this might have caused..
