Phat PS3, siren beep. downgrade

Recommended Posts

HI 

I have a Phat PS3 that I downgraded and patched the nand to 3.55.  I wanted to finish the downgrade in Factory service mode and used My dongles to access FSM but My dongles did not work, I tried with an old Ipod 4g and with and with a USB SPI flasher (PIC18F2550) but non worked so I tried to exit FSM Mode By putting  Lv2diag.self and PS3UPDAT.PUP on a flash disk in the right usb port but now it siren beeps.

 

Please help 

 

Thanks so much
