30w 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.
i'm sooooo glad i sold my ps3s cos chances are i'd have bricked my dex playing with this firmware. yes it would have been my own fault.
same as all those who bricked on the 4.25cex cfw , its not rogeros fault. anything we do to our ps3s is our own responsibility. Aim your hatred towards Sony not each other.
rant over .. lol
Both CEX and DEX are equally capable, with the exception of the latter being able to use the debugger and freely upgrade/downgrade (until now)
IIRC when this whole CEX -> DEX conversion stuff came out a dev said that "the only way Sony's checking this is if they go to EID5, as instructions didn't account for changing that"
In either case, CEX or DEX, it'd be handy to have a flasher. You're playing with custom firmware. Get one if you want to make sure playing around won't hurt.
Finally, I think it'd just be a matter of time before newer DEXification instructions are posted, this time accounting for modifying EID5.
BTW I do not wish anything bad to DEX users.. It's just a shame for them for not making the right choice, Why would we want dex users to have a bad ending? I mean, it's excelent that with this news you can be warned and do not brick it, PS3 costs a lot, and even more if it is with a CFW.
I'm hoping he replaces the whole console or at least the motherboard as its a 60GB he killed. I have a NAND backup all ready to restore back to CEX but as the chip is now missing a few legs its dead.
Lets hope I can get another PS3 to test out all these new firmwares and hopefully the next one will be able to install the progskeet and live.
