yea I can't get it to work either - tried everything whenever the system reboots it asks me to plug in ps3 controller via wire but as i previously stated unless the ps3 controller is plugged in before ps3 boots it will not register only way to plug ps3 controller in before boot is to remove either usb that contains contents of DeV_FLash or the JB either way it will not boot.
I formatted usb and tried - tried again copied contents multiple times mine is not hanging at a black screen and it does reboot as intended but will not boot dev_flash from usb... any other help? I'll have to try more later as the GF is up and she wants to watch tv - whatever!!! This will have to wait until she goes to work at 3... Seems so long away!
