About 4.30 DEX

4.30 DEX: Do *NOT* install this on a converted machine, it will result in a brick. There is a check on eid0(!) in lv1ldr, that will trigger a panic (fun fact: it's impossible to generate the checked data yourself, so no cex2dex without ugly patches anymore).

As always, keep in mind these PUP updates will currently NOT install on a retail PS3, and so they are intended for examination and comparison purposes only.

We have 100% confirmed that running this updater on a retail PS3 will not damage it, however, it will give the following error before the installation completes: The data type is not supported. (8002F029)

Hi there. About 5 days ago i was running Rebug 4.46.1 and i had made it DEX PS3. That night my PS3 suddenly froze and i had to pull the power plug out to try turn it back on.

When i turn it on it goes straight in recovery menu and says i need to update to a version higher then 2.50 as the system cannot run on this firmware.

My PS3 was running Rebug 4.46.1 REX so I didnt know why it asked me for 2.50. I tried every firmware and cfw and ofw but none worked. Then after spending about 40 hours looking for a solution i found a download that sort of takes your DEX away or something. I installed that and my PS3 restarted and looked fine. It then said i was running firmware 3.55. If i go to system update it says i need to update to a version higher than 2.45.

I installed rebug tool box and it said my LV2 kernal was CEX and my Target ID was DEX. I cant install rebug or any firmware. Every firmware i try install comes up as 3.55 and is grey and i cant select it. I installed multiman and looked at system information and it said i was running firmware 0.00 DEX Please help!! Any solution gratefuul and will be tried

Hello people,

I want to downgrade my ps3 from 4.46 to 3.55 so i can install MLT Dex firmware 4.41. The ps3 has no working bluray or logic board. There is something im worried about. Will i be able to downgrade from 4.46 to 3.55 without either bluray or logic board? i think rogero downgrade is no BT/logic board patched, but i'm wondering about the part where i need to QA Toggle the ps3. Is there a way to enable QA toggle on 4.46 or 4.50?

MLT cfw 4.46 and 4.50 has a way of launching homebrew without bluray or logic board but i dont think i can with cfw 3.55. My plan is to upgrade from 4.46 to 4.50 MLT first to pick up eid_Root_Key that is needed for dex firmware, downgrade to 3.55 then back up to dex 4.41

i really need help with this since i dont have a flasher + its PHAT 60 gb ps3 meaning if i fail then flashing it would be a lot harder/expensive. Much cheers for any replies/comments!

This is a nice tut. But can be very confusing for some people. I give you props for writing this up..

Note: Guide is almost the same for Rebug 4.30 users, simply dump your NOR/NAND on 4.30 - though this should be obvious anyway :dumb:

CEX2DEX using Rebug CFW 4.21 by Derektrotter

Downloads:

c2d + openSSL: [Register or Login to view links]
eEID_RKDumper.pkg: [Register or Login to view links]

Preparation:

Dumping EID root key

First you need to dump your EID Root Key which must be done on 3.55 cfw (downgrade using the 999 pup if needed).
Install and run the eEID_RKDumper.pkg, the PS3 will just show a black screen and beep several times. You can now restart the PS3 and retrieve your eid_root_key from /dev_hdd0/tmp/.

That is all you need from 3.55, you can go back to rebug 4.21.

Dumping NOR/NAND

You can do this on rebug 4.21 using the toolbox.
Find the option "Export Flash to File", this will dump it to USB001 (right slot).

Converting your CEX dump to DEX

First download and extract the c2d_openssl.rar to C:/ and install openSSL, this is required for c2d to work properly. Make sure you rename the folder to "openssl".
Now take you eid_root_key and your NOR/NAND dump and place in the folder with c2d.
Rename your original CEX dump to flashCEX.bin
Add .bin extension to eid_root_key.

Should now have a folder like this:

s3nint3!
Open a CMD window in the current directory (CTRL+SHIFT + right click > Open a command window here)

Your CMD will look something like this:

c:\c2d>

So type in the command like this:

c:\c2d> c2d.exe eid_root_key.bin flashCEX.bin flashDEX.bin [target id]

(Note: Do not put the brackets when typing in your target id.)

Here's an example:

s3nint3!
Should give you an output like this:

s3nint3!
If you are unsure you have done it correctly, you can convert back to your original target ID (mine is 87)
Then compare this one with your original and they should match.

Switching to DEX using rebug 4.21

Take your two dumps (flashCEX.bin + flashDEX.bin) and rename as below:

Rename your original CEX dump to CEX-FLASH.EID0.NORBIN (16mb) or CEX-FLASH.EID0.NANDBIN (239mb or 256mb)
Rename your converted DEX dump to DEX-FLASH.EID0.NORBIN (16mb) or DEX-FLASH.EID0.NANDBIN (239mb or 256mb)
Then place on USB001 (right slot)

Load up Rebug Toolbox and first click the option:

s3nint3!
A couple of warning boxes pop up, click YES to both.

Now Swap LV2 kernal, reboot and you are in DEX Mode within 10 seconds

s3nint3!
Switching back to CEX

Very easy, simply rewrite target ID and it will auto swap lv2 kernal to CEX.

To access PSN in DEX mode, there is a feature in Rebug Toolbox to spoof IDPS. Choose EID5 and you will be able to sign in fine. Btw, if anything in this tut doesn't make sense - let me know so i can make it even more noob friendly.
