Ultra 8 Factory Reset
So what has happened is the
- push-pin-in-small-hole for ten seconds reset started the restore process,
- then the front small display offered several methods of how to connect to do setup.
- One of these is ‘web 192.168.1.1’, but that conflicted with the tcp link router also on that ip. I recalled that the ISP Router was allocating via its DHCP the WAN address of 192.168.40.229 so I tried that in a browser and it connected successfully. Asked me to create account details so I used my existing account, then after that slightly laborious process it offered me restore from the latest cloud backup which is currently in progress & worked very nicely.
