[help!!!]"encryption unsuccessful" after flash CM11 over CM12.1.

[goouvw]

My nook hd plus was working fine with cm-11-20150824 and TWRP recovery 2.7.1.0. Then I followed the thread of Unofficial CM12.1 and successfully updated to CM12.1 and TWRP 2.8.7.4. After that I decided to go back to CM11 with TWRP and my previous backup by TWRP. Then very time when I flashed CM11, after booting, the screen shows "encryption unsuccessful........." Now I can only flash back CM12.1 and it is working fine, but how can I go back to CM11?

Solved!!!NookHDplus-bootable-CWM-6046-for-emmc-BOOTFILES-rev0-(07.13.14). Found format data/media in advance menu and formatted everything I can find.
