EDIT: Oops, sorry. Just re-read and see you had Factory reset which would have wiped out your home wifi settings. That would keep this suggestion from working.

I recently ran across this on Reddit. I haven't had occasion to try it but it sounds like it would work.
How to set up a new net connection without a Roku Remote.
You need all of these:
-- A Roku that is still set up for its prior network. If it was no longer connecting to that network when you shut it down, this process won't work and you'll have to use a remote to set the Roku connection up.
-- Knowledge of the network name (SSID) and password the Roku is currently configured to use.
-- A mobile phone with WiFi hotspot capabilities.
-- A second mobile device, either a phone or tablet, with the official Roku (not TheRokuChannel) app installed on a second device.
If you have all these things, here's how you do it:
1) Configure the WiFi hotspot on your mobile phone to use the same network name (SSID) and password as the Roku is currently configured to use. When you turn on this hotspot, your Roku should be able to connect to it and through it to the internet. You just won't be able to control it yet.
2) Connect your second device (phone or tablet) to the first phone's WiFi hotspot network.
3) Now that this second device and your Roku are both connected to the same WiFi hotspot, you can run the Roku app on the second device to gain control of your Roku using the app's remote control capabilities.
4) Using the app, set up the new network on the Roku, via Settings > Network > Set up network.
5) When the Roku connects to the new network, change the second mobile device's WiFi settings to this same network (SSID and password).
6) You can now continue to use the Roku app on the second device to operate your Roku on the new network.
7) The Roku is no longer connecting to your phone's WiFi hotspot, so you can shut that down. If you wish, you can also install the Roku app to this phone and use it to control your Roku as well.
