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 have seen a few ps3s with this problem and each time it comes back to having to hook up a progskeet and flashing the nor dump back using the progskeet powered by the USB. Post up your dump you used to write to the ps3 and I will check and see if it is good or not. Thanks
the fix for 10 beeps semi brick no use to you now, you need to fix the ylod, and to do that you really need to know the cause., was it coincidence , overheating etc. ?
there is fixes for ylod but you've had ps3 apart and reflowed etc. you could have created a problem that wasn't there. i'd strongly suggest you put a message in the forum for ps3 unbricking and downgrading service racer is the best person to talk too about this, hes busy but he wont ignore you.
