I've updated my PS3 to Rogeros CFW 4.21 the first day after release and bricked my Console. Only black screen, nothing else. Now I received an E3 Flasher and tried Rogeros recovery method.
I wrote the patched NOR, now I try to enter Factory Mode but my PS3 only beeps 3 times every time I press the eject button. It beeps 3 times even if the console is powered off and the eject button is pressed, but the Console won't power off.
I also tried to soldier E3's SBE point to TRISTATE and wrote the NOR again. Effect is the same. Beeps 3 times eben if powered off.
What else can I try to recover my console?
It's a CECH-2503B with 0D Date Code.
