Need some help please guys and dolls.

In the WIKI it states :

After it completes, simply format your microSD card, then using filebox delete nitdroid's installation folders and files that were copied to home: bin, data, dev, etc (symlink), initrd, lib (symlink), mnt, proc, sbin, sdcard, sys, system, tmp, usr,default.prop, init, init.nokia.rc, init.rc

Should i delete the folders: bin, data, dev, etc (symlink), initrd, lib (symlink), mnt, proc, sbin, sdcard, sys, system, tmp, usr,default.prop, init, init.nokia.rc, init.rc ??

I want to try and delete all of nitdroid and start afresh. Have been able to install NITdroid 008 and 009 but appear to have the unknown operand error, when installing gingerbread.

Kind regards from sunny (yes sunny) UK
