Could anyone provide a detailled description for what is actually required to update the firmware on the M92? It used to work for me at least two times but it does not work any longer (with the latest update in Booxtor's thread). After showing the "Checking for updates" message, the device just goes about booting as usual. After all, the updates are of little use if they can't be applied.

For what it's worth, the reader appears to at least recognize the card. After it has booted I can browse the SD card on which the device lists the file "update-20130717.zip" as expected.
