I was just curious (my xbox is softmodded) and I want to know how to "Hex" my xboxdash.xbe so that I can reload my original xbox dashboard is that just signing it with habbibi code or what, because i've tried that already and it still doesnt work.
any help would be great
I had installed a Xenium a few months back that would not load the XBox dash with an error 21 and I fixed by:
1) ****** Disconnect the network cable ******
2) Insert a recent "Original" XBox live enabled game (I think I used Full Spectrum Warrior or Riddick)
3) Within the game try to go to Xbox live and it will update your XBox's c:\ with new files from the disc. It will eventually give a connect error since the network cable is disconnected which is to be expected, simply ok through it until you return to the games main menu.
4) Reboot Xbox
Since the game disc updated the XBox's c:\ with the most recent live & xbox files from the game disc all the files for the MSDash should be matched and allow you to boot to it now. I haven't had a problem since. I'm assuming the live version on the disc has to be more recent then what's on your XBox for it to update but i'm not sure.
Something to try 
*edit spelling
Nice!
I had the same problem as you, but I just followed CubanX's advice and it worked!
This is how I did it:
1) -*-Made sure network cable was unplugged-*-
2) Booted up EvoX (modchip on)
3) Stuck Halo 2 in the drive and pressed "Launch DVD"
4) In Halo 2 I went to Xbox Live
5) Halo 2 copied over files and when it was done it said it had a connection error
6) Just press Yes or Ok for anything you see until you are returned to the EvoX dashboard (or maybe into your games' main menu)
7) Turn off Xbox
8) Turn modchip off
9) Boot up your now-working MS Dashboard!
Thanks Cubanx,

nice! works here too. I thought i was gonna have to download slayer's autoinstall to get back my ms dash. Nice job guys ty!
i am having a problem with getting my dashboard up and running...
i just installed a X2lite 2.6 on a v1.1, it installed great and is flashed with a m8 bios, and i have 2 modded HD's that used to be on a v1.0 with a matrix, they never had a problem. but now with the new X2 chip all i ever get is "error 13" i have tried formatting and reinstalling with slayers, i can ftp using a boot cd i made and everything is there on the HD's for evox to run but i never does...
(in short, dashboard was working with matrix, now is not working with X2lite).. WHY?!?
I can't answer your question, mum1111, however I think you should start your own post in the appropriate section instead of something irrelevent at the bottom of someone else's thread.
Excuse me if you're actually talking about your MS Dashboard (then this is the right place!)

mum1111 - Make sure your harddrive is locked. Error 13 is a unlocked harddrive(I think)
