Issue with the PS3 harddrive. 0x8002F281 Issue with the PS3 harddrive. Reboot system and use Recovery Menu options. If error persist, Format the hd on a pc, reinsert it to the ps3, install update (normal/recovery mode), format hd on install. If still not fixed: exchange harddrive
So with the hdd, seeing you have tried many and its not working in Recovery. You may need to go into FSM to install the CFW using a downgrade Dongle.
As for the Wifi/BT board, check the connections
