Blu-ray Backup Firmware?

[immortal001]

Having got the PS3 2 days ago AUS 1.50 FW im now looking into trying some blueray backup. The only update available here is 1.60 (currently avoiding like the plague) I've read in various posts that the dump command doesn't work above 1.54? What is the minimum firmware for backup and what firmware does it stop working on? Any help would be great as don't want to go to high as this is my on blueray source.

Why not just leave it at 1.5 then? I have 1.54, and the dd command still works, but I'm sure not going to update to 1.6!

The 1.1 firmware is posted here (and is the minimum required):

Why not try for yourself and see, it isn't going to hurt anything to try is it? no. Also try posting this question in the right spot, like the sticky about Blu-Ray backup maybe...
