Today when I started my xbox 360 slim it said i had an xbox update. So I updated and the xbox restarted, but when the update is supposed to apply it says "Can´t read the update from your xbox 360 hard drive. Please reattach it." Status code 351F-3524-2380-1315-C000-0185 i´ve reattached my external hard drive but it won´t work. I can´t even get to dashboard, even when i turned of my internet. So I`m stuck at that white screennote... I´ve tried to find a solution in the forum but can´t find any help!! Can someone please help me!!
