Okay, so I got my rah december 1st, it died december 22nd, I left it on for two hours, when I went out for dinner, and never worked again, but it will boot into cell, but not the dashboard, any help would be massively appreciated, and the helper will get something in return.
put "xenon.elf" with the file you wish to flash called "nandflash.bin" and boot into xell , it should do the rest for you
make a new nand just like any other time you was to update then , Copy updflash.bin to the root of usb drive formatted as Fat/Fat32. Ensure XBOX is off, Plug usbdrive and turn the xbox on so that it boots into XELLOUS and watch it flash your nand. Follow the on screen instructions. When power cycling ensure XBOX is unplug and off for 30 seconds.
wow , sounds troublesome indeed. i can only suggest a good reflash , or maybe a reflow and new paste & such.
