I've tried fresh downloads of each exploit, both Krayzie's Ndure 1.1 and the softmod deluxe 2.0 three times each. Same result box just locks up. and yes i make sure to delete the "old" one off the xbox and out of Action Replay's console each time. so i know the new one is being tried.
You might also try to find a friend with a chipped xbox and get them to put the save on a memory card. Might not make a difference, though; just the way I did it.
Problem here, where i'm at i believe i'm the only person with an xbox for about 20-30 miles... believe me, i've asked my "gamer" friends if they had tried this and they all said "f**k the xbox get a d**n playstation."
i am open to other softmods if they are fairly noob friendly. just dont know about em. i've read mostly on the two that i've tried.
