Problem solved ME301T now boots past encryption
I still can't get logcat output from CM11 Unofficial. What I did notice with the Crombi-KK ROM is that as in the previous post the failure occurs when the /data directory fails to unmount before the encrypted partition is mounted.
On Crombi it also appears that Wifi is broken. It looks like /data/wifimac does not unmount. An application that needs to run in order to build nvram.txt, wifimacwriter, fails because the file /data/wifimac/wifi_mac is missing (partition mmcblk0p5). Creating this file solved this problem and Crombi seems to boot past encryption.
It is possible that in my vigorous flashing and wiping of various roms I whacked or corrupted the partition mmcblk0p5 containing this information. Although strictly not necessary, it seems wifimacwriter fails if the files don't at least exist.
In short, the fix is as follows:
So it seems my hypothesis in post 1, that the problem might be specific to my tablet, was correct - I broke it. You may all disregard these 4 posts. Carry on, nothing to see here...
# mount -t vfat /dev/block/mmcblk0p5 /mnt/sdcard/tmp/ # Any convenient mount point will do
# touch /mnt/sdcard/tmp/wifi_mac
