Here is my theory on how it is possible to make a copy of the dev_flash from almost any fw, old and new.
Can some one with a infectus chip and a JB pleas test this out
First flash the ps3 nand's to fw3.41,then start the ps3 with JB and install
USB Firm loader and FTPserver 1.0, then make a copy of the dev_flash to a usb stick.
Then start the Firm loader, while you are runing the dev_flash from the usb, flash the PS3 nand's to fw 3.50.
Then use FTPserver1.0 to acess the dev_flash0, this should contain the 3.50 fw!?
If this works, and i can't see why not, it could be done with any fw that people with the infectus chip have a made a copy of.
And no, the dev_flash is not locked to one ps3. I have tested.
And it does not contain any personal information.
I have hash ckecked two dev_flash folders, from two differnt ps3's with fw3.41, one Fat (US) and one Slim (EU), and they are identical.
The xRegistry file may also change between the different fw's,like entries for enabeling OtherOS on the old fw's and more 3D settings on the new fw's.
