Ok, So, i was messing with the xboxdash.xbe trying to do something that my friend told me. I made a backup before i started, just in case. Well, i messed it up and so i restored the file with my backup. I booted my xbox and i got error 21. and so, i was like, WTF. So, i busted out my backup cd that i made a looong time ago when i first started everything. restored xboxdash.xbe and the folder xboxdashdata.17f14d00, because i heard somewhere that they were linked. i still get an error 21.
help pretty please
