This initial install attempt failed-- GT-AXE16000_3006_102.7_1-gb80bd846c0 --and the router reverted to Current Version : 3006.102.7 after the required manual reboot. Like many of the latest upgrades, the hard manual reboot is called for in the software dialogue.
Not sure why the _1 is being rejected on the 16000??
Tried it again with the same failure to install...
