[General Questions and Answers] bupkus:
To preface: History--I have some experience installing tenderloin mods for hp Touchpad. More currently, I spent 2 days reading about first, an SD Install for my nook HD+, and then an emmc install for same. I felt ready to go forward but did not prove a smooth process.

To date, I have verygreen's process executed with the following issues:

Failed gapps install...I believe.

Notification of processes being stopped, ie, clock.

Cannot log onto Play Store--"Authentication is required. You need to sign into your Google Account. Retry" Pressing Retry loops back to same message.

Oddness or unexpected results:

I expected all my apps and accounts to disappear with Rom install but all and perhaps more exist. My gmail app and account opens with emails from time before install but no new downloads since. Internet works as wi-fi connected fine.

Procedures that got me into this pickle:

1. Using Pretec 8GB Class 10 Micro SDHC, which btw my nook found fairly easily, I used the following sw to prep and populate it for install.

a. win32diskimager-v0.9-binary

b. sdcard-cwm-early9.img

which btw reduced my Micro sdhd partition to just the minimal size needed to perform the needed function w/o space for rom or gapps. Grrr

2. Downloaded cm-11-20140303-NIGHTLY-ovation to "download" folder inside nook...yes, I forgot both the cwm-recovery-ovation-6 and the gapps.

3. Began to install NIGHTLY and rebooted but as you probably expected it stopped at "nook".

4. Rechecked verygreen's procedure list with facepalm, tried to install forgotten files onto flash mem where there was no room(see above), rebooted into nook to download missing recovery file and pair of gapps files -- pa_gapps-modular-full-4.4.2-20140301-signed and pa_gapps-stock-4.4.2-20140301-signed

5. Install begun with boot to flash and then, yes then decided to use cwm to backup pre-existing rom. Tried to backup to /sdcard with following android reply:

SDCARD cwm-based recovery v6.0.4.6

SD Card space free: 6133MB

Backing up boot...

Backup of boot completed.

Backing up system...

Can't mount /system!

6. Perhaps a backup to emmc?

SD Card space free: 4495MB

Backing up boot...

Backup of boot completed

Backing up system...

Can't mount /system!

7. Oh...I'm not done (it was late).

Choose default backup format

tar (default) //why change something I don't understand?

Default backup format set to tar.

CAN'T SEEM TO SOLICIT A WAY TO BACK OUT OF HERE! Later I discover the power button as backout, but until then...

8. free unused backup data

Freeing space...

Choose an image to restore first. The next menu will show you more options.

Advanced Restore -----------Upon reflection, perhaps I shouldn't have proceeded

--Restore boot

--Restore system

--Restore data

--Restore cache

--Restore sd.ext <<== this one looks interesting

Yikes! Finally found power button

//Reboot and install of forgotten recovery file, then Rom. Rebooted, downloaded 2 gapps files(see above)

I guess what I am hoping for is a forensics examination(but not in depth). I hope the excessive detail can be skimmed for a quick assessment of my nook's status. IOW, is there a simple fix. Should and can I start all over?

Thanks for whatever help is offered.
