If the flash went OK, i'm not really sure what the problem is. There are a few things i can think of. Is there a soft mod installed. Is there maby a BIOS setting that affects ACPI? You can try to ask Jimmy rollins how he did it. He reported the mod as working.
I havn't installed any softmod's, and i always load the default settings in my BIOS before flashing. Yeah I PM'd jimmy about a week ago but there was no reply. I'll keep trying to flash it.
