As far as I am aware, the Libra Colour came with 4.39.22801 as the factory installed firmware. No 4.38.21908 firmware version that I can find comes with the update directory containing the upgrade directories for the Libra Colour, Clara Colour and Clara BW devices.

For instance the 4.38.21908 upgrade for the Elipsa V2 is the only one in the 4.38 family that has a mt8113t-ntx directory in upgrade and the only directory inside that directory is named EA0T00-A0x30. By contrast the upgrade/mt8113t-ntx directories in the Libra Colour, Clara Colour and Clara BW all contain 4 directories named E60T00-D0x00-OFF, E60T00-D0x00-ON, E70T00-A0x00 and EA0T00-A0x30. It's almost tempting if I had a Elipsa v2 to install the 4.39.22861 firmware for the Libra Colour.
