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.

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

damnit i find this out after i order one...typical. well at least the author is working on a solution so perhaps by the time it arrives the problem will be resolved.

thanks for the info, im really glad you let us know because otherwise i may not have known about it.

EDIT* it seems im off the hook in a way - i cant order it from pjrc.com because the card was declined for international transactions. they were kind enough to direct me to a European distributor but its a good bit more expensive (relatively speaking) so i may have to go with progskeet after all. the teensy is still cheaper but its not as good value especially when you consider it wont work with my ps3 atm. progskeet of course is twice the price hence the reason im hesitating, especially for a device i might use a handfull of times so im not sure about it. anyway sad but a little glad as well.
