[MENTION=3657]pinky[/MENTION] (happy to hear from anyone else with a suggestion too) I decided to update my xbox dash to 17489 and I've used both jrunner and xebuild with the same result. I keep an error when trying to update in xell. The error says: "block 0x1b7 seems bad, status 0x00000218 Block cannot be recovered (A.K.A. it's really bad)" Then it finishes flashing the rest of the nand and when the xbox starts up, it hangs at the xbox 360 screen (although it does sign me in) Any suggestions? FYI, it's a trinity motherboard and I've had those same bad blocks in the past but it always just remapped them without a hitch. Any help or suggestions are appreciated.
