Thanks. Have you tried CM10.1 yet?
To stick with CM10.0, "cm-10-20121231-NOOKTABLET-acclaim-HD.zip" is the correct, most recent file, right?
Also, is it OK to do the back up to the same SD card (8GB), with just one full (8GB) partition, that has the same files used for the flash? And some posts talk about partition size. Is that only a concern when booting CM from the SD instead of eMMC?
