So I bought this Trinity Slim, the seller was an idiot and put everything on the HDD including XBLS on it. I remove the files and just like that the hdd doesnt work, I reformat, removed everything, etc etc, now when I plug in a blank hdd after the boot animation the xbox just turns off. without it its fine and turns on, but as soon as i put the hdd in it doesnt boot up. I tried a new launch.ini on the drive, I formatted it on the xbox (By plugging it in via usb) and still nothing works. Any ideas?
