Not quite. These are "update" files, which will take you from an older version to the latest Dingo version. These preserve your data, settings and apps. You cannot use these to go from Ermine back to Dingo.

The other set of files are "Golden" update files. These do a complete wipe & reformat of the eDGe and install the latest Dingo version, regardless of what older or newer version you had previously. They also wipe out all your data, settings and apps.
