To the guy that bricked his 3550 trying to crossflash it. Look in the bios see what the bios recognizes the drive as, should still see it as a 3550. Download the NEC flasher for the drive from Nec. Boot up in safe mode and flash the drive with Nec's flasher. That is your only hope. I hope this thread doesnt get deleted as it is not help for crossflashing but just help trying to recover the drive to its original form.
