Get a Nook HD or HD+ For XMas? How to Get KitKat W/O Voiding Your Warranty
Any parent (or hey, adult) may have picked up a Nook HD or HD+ for Christmas. Any flashing voids that pesky one year warranty should anything happen to it (lovely fine print, lol). There are alternatives out there. Why pay one of two commercial entities for Android-on-a-Card when you can roll your own?
The dual boot scenario that doesn't void your warranty requires a MicroSD (Class 4, or Class 10 aka UHS-1), access to a PC or similar, and some downloading. Got both kids a Nook HD+ and I heard whining (spoiled brats are used to iOS on their iPod Gen 4s) so looked into this. You can convert the tablet to boot either the standard Nook, or Kit Kat via MicroSD.
Just followed direction myself on my youngest's tablet and voila --- Kit Kat on a Nook HD+ (works for Nook HD as well, just different files). Check it out here.
