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

Sponsored Links
104w 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.

verified.. it's correct eid_root_key .. thx to you know who you are

now the other part... any hints on this part guys... thx

is aespipe used for AES encrypt? the original guide is kinda alien like, i bet they do with a blink of an eye...., any help on the command to put in terminal like:

use AES Encrypt to Encrypt EID0 Key Seed as data with EID Root Key as Key and EID Root IV as IV

aespipe -e/ aes256 eid_section_key_seed as data? bin file? -? eid_root_key-o root_iv key
something like that right

hi, hopefully anyone can give some feedback, tips

installed the manual ubuntu way from gitbrew guide
added the metldr from the ps3 into metldrpwn folder
transferred to root folder in ubuntu (rebug otheros - no ss patches)

in terminal:

[Register or Login to view code]

it finished without a problem, and dumped couple files:
debug : pastie >> [Register or Login to view links]

[Register or Login to view code]

does it look OK, pls anyone verify for me, or i can upload incase needed

dump 256kb (first 3 lines looks to be the eid_root_key?)
if OK, then "new file" in HxD, copy the 3 lines from dump and "paste write" into new file - save as eid_root_key.bin and move on from there?

eid0 4kb (all zero's-00)

great stuff anyhow

and thx for any help

I think that you need to downgrade at 3.55 because you can't encrypt / decrypt on 3.60+, and you can't dump or flash the NOR without a flasher.
