softmodding problems ERROR code 13

hey i softmodded my freinds xbox but my freind tried to get the MS dash board back. NOW it says your xbox requires service and the number 13 on the side. I dont know what to do

 

use the game, that you used to softmod, to load the linux file in xbox.

 

Try all possible way to get the ms dash back.

End up that you can't fix it. Then do the hotswap here. If you have questions, reply over there.
