PS3 CEX to DEX Converted Units Bricking on OFW 4.30 DEX Update


Sponsored Links
92w ago - It's been a few months since the last PS3 Debug / Test (DEX) Firmware 4.21 leak, however, we are now hearing reports that PS3 CEX to DEX Converted units are bricking when PlayStation 3 scene developers attempt to upgrade to Sony's OFW 4.30 DEX update.

This means if you have a converted unit and currently try to use the (not yet public / leaked) 4.30 DECH update you will get a brick... so consider yourself warned in advance!

What happens is when the bricked unit is powered on the light turns green for a few seconds, then you hear 3 beeps and its goes off.

It is suspected (unconfirmed) the reason why this bricking occurs in CEX to DEX converts on OFW 4.30 DEX is because the EID5 isn't changed, which is one factor separating the converted Retail to Debug / Test consoles from genuine and righteous DECH (DEX) consoles.

Finally, for those curious, the PS3 4.25 DEX update (also not publicly leaked yet) is not patched by Sony to brick converted consoles, so this would be the last PS3 Debug / Test Firmware you could update your converted console to (and go online with PSoN DEX) unless a work-around patch fix is discovered.

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.

dump the NAND/NOR backup using hardware flashser and then restore the targetid back to retail one and use rogero flash downgrade app in PC and use your NAND/NOR backup to patch it and then flash it back to your PS3. Then it will remind you to reinstall a firmware after you turn it on, install a CFW that you want to use and youre done.
