this is exactly what I did for everyone to follow if they wish.
As you will see I´m going to use a DVD-R because everything will not fit into a CD-R
1- used the ndure 3.1
2- chose the settings that I wanted using
this and
this.
3- before using the make-iso-win.bat file I copied a C backup(a totally untouched C) into the "app" folder and all my xbox aplications backup - from emulators and roms to some useful stuff - and of course copied my eeprom file into its designated folder.
4- used the make-iso-win.bat file and waited a couple of minutes and the iso was there to burn
5- burned the iso with ImgBurn. it was 2.5 GB!
6- prepared the xbox and the PC for xboxhdm
7- unlocked the drive with unlock utilities******* unlock -a (remember that I copied the eeprom)
8- used xbrowser to delete everyting in C and E
8- used xbrowser to copy the backup of C
9- used the ndure script
10- waited patiently for it to finish (around 20 minutes, I´m not joking)
11- reboot it and locked the drive
12- put it into my xbox and it was good to go
13- checked it and UnleashedX was the dash, of course. I was able to use the MS original dash
and even all the apps I copied were there
14- using the UnleashedX´s xplorer I opened xbmc. with xbmc´s xplorer
I deleted all the files inside "dash" folder on the root of E.
15- then using the same xplorer in xbmc I copied ALL the files in the xbmc aplications folder
to the "dash" folder on the root of E.
I just hope this can help anyone as it helped me.
