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.
See link bellow for image download.
