The NookDevs team have released a new version of their firmware for rooted Nook e-readers. Released as v2.4.1, it’s based around the 1.4.1 released by Barnes & Noble a short time ago. Those of you with rooted devices will be pleased to learn that some of the features included this time around consist of a file management system, helper scripts, and a fix to allow non-market app installations and upgrades. A full list of details and rooting instructions can be found at NookDevs.
