DV4mini Firmware and Software Upgrade on Raspberry Pi 2
I received a lot of questions about the DV4mini software upgrade on the
Raspberry Pi 2, this video is showing how to do it easily. It also
included the firmware upgrade procedure.
Note: In the DV4mini
directory the Archives folder is not there by default, you need to
create it. You can also just delete the older file you need to replace.
