Help request: upgrade failed, locked out at decryption passphrase

[Zebulon Walton]

One thing that's good to do once you get your eMMC installation sorted out is to use Jumpdrive to make a complete image backup of the disk. (I do this periodically.) That way if something happens that messes up your installation you can easily recover using the latest good backup. (I've already done this once, saved a lot of hassle by doing that rather than having to redo all my customizations on an out-of-the box installation.)

Some recommendations on utilities to do backups are in this thread:
