Ok here's the deal. I have an 80 GB fat CECHL08 model, OFW 4.21. Using an E3 I followed the steps to downgrade till I have to enter FSM. This is where I'm stuck.
I turn on the switch on the back, plug in the jailbreak in the USB closest to the BD drive, press power and quickly eject. The jailbreak dongle flashes about 5 times and then the screen shows
"Connect the controller using a USB cabl, and then press the PS button"
It doesn't shut down like it should. What am I doing wrong? Help please! I've been at it for 12 hrs now.
