OK i got it.
To unistall whatever you want, just delete the files, use boxplorer
To edit the ini, update files, or anything else, create from your PC (the os is no important) an is0 9660 (i think), cdrw close the session, no multisession, that includes everything you need, from edit ini to dashboard updates to emulators you name it. Then load the xbox (dashboard like evox) start the appication dvd2xbox (the boxblorer won't recognize it) and copy the cd/cdrw/dvd/dvrw to e:/games or f:/download, or everywhere else. The by using the filemanager of your choise, just add the files/folder to their respected location (ex evox.xbe to c:\, applications to e:\application\program_1) and reboot to main dash. That's all
and now a message for the ones who can read it
