The main thing you will need is nookLibrary. The current version is
here.
There are a number of ways to load it onto your nook, some at nookdev and some here. I used Android Commander. Unfortunately, there are no simple instructions, and everyone has pretty much abandoned the nook as far as hacking goes. nookLibrary is essential and solved all the library and file management problems of the B&N software, which is just terrible and buggy.
This is important, and I am assuming that the softroot you installed had the basic package of apps, just not the new version of nookLibrary. Version 1.0 is pretty basic; I don't understand why they are still including it after so many updates, but as I said; no more interest in the old nook.
