So you have done the following, right? Full manual installation...? If you have done this and you're still getting an error remove all partitions on your internal eMMC and run it again - I didn't deliberately partition my eMMC rather I simply went for it, it may be a ball-ache to remove all the install files from /home manually but never mind, I don't intend to uninstall 'droid till the next release anyways.....
