2. Sideloading Apps
Once Unknown Sources is activated by my CWM zip above, you do not really need to install apps this way anymore.
Once you have ADB connected to your HD/HD+, it is very easy to sideload install apps. Just have your command prompt set to the location that you have your apk's stored and type "adb install xxx.apk", where xxx.apk is the name of your app. It is best to name the apk to something simple with no underlines or special characters in the name. It does not matter what you name it, the real name is inside the apk. The app should install. I would start with a launcher app since sideloaded apps cannot be seen in the stock launcher. Then I would install AnyCut which I have attached to this post. This app allows you to put the Home command on your launcher's home screen so that after you make your launcher default, you can get back to the B&N home page. There is a trick mentioned in the B&N guide referenced above that lets the stock app drawer see your sideloaded apps. On the Apps screen, hold the volume up button while you press the "Apps" word at the top of the screen for 2-3 seconds. An "Extras" screen will pop up showing all of the sideloaded apps. You have to do this every time you want to see it.
First let me just say, I know I should probably just pitch the nook because oh man... it's so old. But I adore the things for my kids' home school apps. I love the separate profiles for the lock features and the ability to turn off features to make it very safe for them. I've tried APK Extractor from an old Samsung S5 to a APK installer to the Nook HD. The files have a "Parsing Error."
The only way I've been able to get most of the incompatible apps on the nook is to use Aptoide which has been great. But the big issue here is that there is no option for me to get my paid apps from my other devices to my nook HD that have been successful.
I have done the old method only to be told by command prompt that I have to use the old KitKat method with which I am unfamiliar and can't see why it would be any different from what I tried in leainlar's original post for this thread. I made sure I had the proper SDK installed on my computer.
All that to say, has anyone had any success getting apps that are paid versions onto their nook HD/HD+'s? This is my last ditch effort before I accept the little guy for what it truly is. A old dog that can't be taught new tricks.
Please let me know if I wasn't specific enough or if there's anything you might need to know of what I did. I'm a little bashful because I'm no more than a tinkerer right now pining after every words you guys say. Thanks a million for all of your knowledge and willingness to share your time and work here on this site.
