Considering the locked bootloader, this change in the Nook Tablet’s software is not unexpected. Barnes & Noble is certainly aware of how popular the Nook Color was and is as a modder’s cheap tablet, and have not raised any serious objections thus far. But as pieces of consumer electronics, the Nook Color and Nook Tablet are sold on extremely thin margins with the expectation that users will buy books and other media from Barnes & Nobles and its partners, justifying the low profits on the hardware itself. Every user who buys a Nook without the intention of using it primarily as a reader for Barnes & Noble’s ebooks is undermining their business model. Since advanced users aren’t breaking any laws, the best that the company can hope to do is frustrate their aftermarket efforts.
The solution for those who want to keep modding their tablets is simple: don’t upgrade to version 1.4.1 on the Nook Tablet’s software, at least until another work-around is found. Those who have already updated can flash to the original retail image and work forward from there. Strangely, third-party apps that have already been installed on updated tablets are still working, so users who already modified the Nook Tablet and gotten it to their desired level of functionality will probably be able to wait it out until someone finds another weakness in the device’s software armor.
