Caveat emptor: adopt/follow this guide at your own risk.
Below is a procedure that can be used to update your HD+ EMMC to LN14.1 from CM11 (if your HD+ is currently running stock ROM, use the process described at https://forum.xda-developers.com/nook-hd/general/how-to-installing-ln14-1-internally-hd-t3562810/).
Once the Nook completes the boot (be patient as it takes quite a bit of time), set up the Wifi connectivity and your Google account info. Note that the Apps you previously have on CM11 will not be auto-downloaded/restored into your new LN14.1.
If you run into problems during initial setup:
- absence of WiFi network setup step: see this post
- setup process crashes (as have been reported with some combos of ROM and GApps build versions): retry the clean install process with the sequence of steps # 6, #7 & #9 (i.e., skipping over step #8 flashing GApps) and complete the initial setup, then reboot into TWRP to flash GApps; see also https://forum.xda-developers.com/showpost.php?p=72104906&postcount=37 for solution for other setup crash causes.
To enable "Root", see https://forum.xda-developers.com/showpost.php?p=72185622&postcount=1915.
Notes
If you encounter errors in step 3 (using your existing CWM recovery to flash the new TWRP zip file):

- amaces' flashable LN14.1 ROM zip file, e.g., lnos_ovation-ota-NMF26Q.170104.zip from https://notredame.app.box.com/s/26a4bygh9vbaw7jjq08xr5evomvaw5ww/1/3332706778

- Boot into your current EMMC recovery.
- Select install zip and install the TWRP recovery zip file obtained in step 1(a).

- Reboot into the new LN14.1.
Once the Nook completes the boot (be patient as it takes quite a bit of time), set up the Wifi connectivity and your Google account info. Note that the Apps you previously have on CM11 will not be auto-downloaded/restored into your new LN14.1.

Notes
If you encounter errors in step 3 (using your existing CWM recovery to flash the new TWRP zip file):
- - If you have a SD card handy, consider using the procedure described at https://forum.xda-developers.com/nook-hd/general/how-to-installing-ln14-1-internally-hd-t3562810.
- - Otherwise, you can try to flash the flashable TWRP zip file available at http://www.mediafire.com/file/3gj4g9j1x363dor/cwm-flashable_twrp-3.0.1-0-ovation.zip.
