It seems that this particular issue is revolving around an issue with "resizefat /dev/mapper/store-media" and the fact that the fat size is different than the backup.
I did a bit of research and came up with the following solution:
Run WebOS Doctor via CMD line "java -jar webosdoctorp302hstnhwifi.jar"
When the Dr. hangs up at 12% open novaterm and connect to your device
Then type the following command:
dosfsck -r /dev/mapper/store-media
And follow the prompts to correct the fat size to the backup (I believe I chose option 2 and then restore to backup and then 'Y')
Now put your tablet back into recovery mode and re-run WebOS Doctor. The error where it is hanging up should be gone and the system will flash completely.
