all ps3s have a region code, bluray movies require this and keys to play. dex ps3 has no valid region code as its target id is changed to 82,
82 is not a valid region id. and dex firmware has no bluray keys for bluray movie playback.

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.
