I am just starting out and am trying to upgrade my HDD in my CECHH 40Gb PS3 with OFW 3.66.
The physical preparation is ok and does not present a problem.
However when I put the new HDD in the system states that it requires FW 3.66 or above. I assume that along with the backup I have made to an external HDD, I also have to have a FW 3.66 (PS3UPDAT.PUP) on the HDD in a folder named UPDATE.
I am in Australia and so far I have only been able to find a US 3.66 OFW.
Finally, my question is, does anyone know if I can use this US FW to reinstall/transfer my backup?
