Grentz; to install or reinstall it, use the Ndure Toolset's 'Install Menu -> 'Install UDDAE' (via /E/ndts/default.xbe).
The following sequence triggers it (and can be practiced via the Eject boot):
[Music] [blank soundtrack] [Copy] [Select] [Copy] [New Soundtrack]
<<Eggsßox>> (that's two '<' Symbols, Shift E, g, g, s, beta Accent 'ß', o, x and two '>' Symbols)
[Done] (uberdash menu loads) [Music] [blank soundtrack] [Copy] [Copy] [New Soundtrack] [Done]

Did exactly as you said, but when I try to make the new soundtrack, it always says "Maximum Number of SoundTracks Reached 100" (or something close to that).
...
And also, can i just use that other dash (the Xboxonline one) to edit my live settings/accounts without having to do the whole UDDAE thing?
{: That error message actually confirms you didn't do exactly what I posted (which no doubt means I wasn't clear enough about part/s of it). ;}
If the first two lines of the sequence are done correctly, something else would happen ... as it's actually an easter-egg in the MS dash itself (that works with any sound track).
Maybe where I wasn't clear enough was "[blank soundtrack]"? By that I mean the empty/no name sound track menu entry that's there after successfully installing UDDAE.
Re. the xonlinedash console, that has the Xbox Live setup and maintenance options ... it's NOT the real MS dash executable in kingroach's 3.0 (NOR krayzie's 1.1[...]) whereas the normal Eject boot MS dash IS the real MS dash executable in kingroach's 3.0 (but NOT krayzie's 1.1[...]) and real MS dash executables are the safest to use on XBL.
