No, you didnt spoil my joy But what do you think of my theory?

I was wrong, and you are wrong

I have hash checked every file, and they are identical. Yes it is a memory dump, a nand flash memory dump, not a RAM memory dump. Nothing changes in the dev_flash, except when you do a fw update.

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.

I just got my second ps3 to day, EU 320GB Slim. My old one is a US 60GB Fat.

The first thing i did when i got it, was to update the FW from 3.40 to 3.41. Then i installed the FTPserver, and copyed every thing from the new ps3. Then i compared the dev_flash on Fat(US) one with the Slim(EU) one, and guess what...

They are identical in size: 177*360*300 byte, but then i tried to compress them winrar and check the MD5 check sums, but the compressed size did not end up as the same. Then i tried with to zip them with windows. They ended up with the same size, but the MD5 Check sum's where not the same.

So there are some small differences between the US FW and the EU FW.

Then i copied the dev_flash from the Slim one to usb stick and plugged it in to the Fat one, and started the Firm Loader. And it worked.

So in other words, it is possible to run the dev_flash from one ps3, on another ps3. They are not locked to the ps3. As some people claim....

My suggestion is to add a Firm loader function in PSgroove, make it mount the usb as the dev_flash in the memory.
From what i could see while updating to WF 3.41, the ps3 did not restart it self, it just exited the xmb, and started the FW update "OS".

And we will be able to update the FW on the usb mounted dev_flash. My other solution is a litle more drastic, but might work. Hook up the nand to a usb controller, and plug it in to a JBPS3, then use FTPserver to copy the files.

Edit: I just finished hash checking all the files in dev_flash on the US Fat, white the EU Slim one. They are IDENTICAL, all the MD5 checksums match up.

If you did not read what I wrote a few posts up, the infectus will only dump the encrypted raw data, and that's also including the ECC data. So unless someone makes a tool to unencrypt the nand dump then we won't be able to do it. We also need to find a way to get the encryption keys.

From what I can see, right now an infectus dump is totally useless.

Can an infectus chip dump dev_flash from a 3.50 updated ps3? Will those files then work in the CFW loader?

I have an infectus and I also have a dead PS3 mobo with the dual nand chips. I can dump them for you guys if you'd like, but I don't think it will do any good at all since they will be encrypted and no one will be able to read whats in them. But I'll still do it anyways.

PM me if you are interested in my doing to for you.

I don't know what the current firmware is on that PS3 mobo, but it's been dead for quite some time so I would assume it's from be 3.0 firmware.... maybe even from around when 2.0 came out.
