I've got a similar problem. I'd like to download and install HiveOS 6.5r4, for the router we recently bought.
The previous owner has messed up the nand (I assume as "good" measure in order not to spill secrets or similar).
I understand there was a aerohive connect page, where one could register ones devices, to download the firmware for them, but that does not work, as the serialnumber is still in use by the previous owner (another VIQ).
If possible, I'd like to know the way to get access to that specific firmware version.
If someone could provide me with details I'd be grateful. Thanks!
