I have a 360 modded Phat with Philips-LiteOn DG-16D2S, I am able to play most of the games once the activation disk is inserted first. I am not sure of the firmware as my son handled most of that. He is not here and he cannot remember either. I believe it was updated using a DVD system update 8955 in the fall of 09. Maybe one more time after that but I am not sure of the FW version. As I said I can play 2012 games using abg 360 and an activation disk. However upon I inserted the Fast and Furious Showdown and upon starting up it required a system update. I started the system update and it stopped partway through with the error status code 3151 3F4A B800 0F00 C000 D059. Now I have spent 2 days researching the problem so that I would not be posting something stupid, as I am definitely a noob. Since we do not have the original disk which is being requested (my son has it 4 hours away), can I go and rent an original version to complete the update, or do I have to reflash the DVD drive. Is there an easier way?
