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
Tutriol and confirmed by moderator of ps3hax his quote on the subject:

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
cheapest compare to $80 infectus $65 progMy review on the item is buy it. It cheap and gets you what you need to do.
