Update 2016-12-30: Since the Olive website does not show the older software versions, I wonder if this would still work. Where would the Olive get this firmware from? So at this moment in time, I do not recommend that you perform this action!
Note that it is entirely at your own risk!
Please verify again that your Olive is on 4.3.2 or else installing FW 3.0 will cause irreparable damage to the hardware.
• Installation of both software and Firmware updates can last up to 10 min.
• The firmware update can be installed by pressing a simple key combination.
• With the Olive turned on, press the following two buttons Top navigation button and Fast forward button, keep both buttons pressed down for 6 seconds and release. This will trigger the installation of Firmware 3.0
• Please do NOT turn off or interrupt the installation process at any time or the unit might be irreparably damaged.
