Cfwprophet over at psdevwiki.com has released a dump of the serial flash MX25L25635FMI-10G for the PS4 CXD90025G which is the secondary/low power processor handling network tasks. The MAC address and Console-ID are zeroed out in the dump. Have fun! [UPDATE]: I found an interesting area beginning at offset 0x144200 in the flash dump, check this forum topic for more info."
