As i was installing Ldots installer my little brother bumped into the xbox while it was installing,will that somehow mess up the installion in the future,It seems to be working fine now.

Probably not, if the harddrive didn't got a huge hit you'll be fine, but if you ever hear clicking sounds from the HDD you better change to a new one.

Ldots is like is super old. You should update to a newer softmod, "Krayzies Ndure v1.1 (+v1.1.1 update kit)" is the newest and best softmod to use.

You can just boot the game you modded it with and the linux save again, then just select to remove the softmod. Then delete the saves from the M$ dash memory section. Then copy the new (Krayzies) saves over and then run the game again to install that softmod.

You could also use CASH v1.1 and wipe the drive and install the same softmod without having to bother with the softmod game and the saves again. Just be sure to backup anything you need before using it (gamesaves, apps, etc.)
