[QUOTE=Quoth;4378436]I think an earlier fw for Glo than current.

The last firmware release for the Mini was 3.19.5761-s which should be installed for the operating system updates (the bits and pieces in the upgrade directory). After that, you can update to the Kobo4 4.38.21908 firmware which seems to work fairly well if slowly on my Mini.
