Setting up a Phantom WITHOUT a Dialog: Any Successes?

[JohnnySix]

I recently took one of my Phantoms to my parents house and spent about 3-4 hours trying to set it up without Dialog via Spark on Android/IOS/Windows devices, without any success. I found the following obstacles:

1) Entering the WiFi password into Spark NEVER let the Phantom join the network.
2) Spark only recognised the WiFi of the Phantom for password entry
3) Consequently, Spark never proceeded to the Phantom Zone allocation (Superman)
4) Resetting the Phantom (3 presses) many times didn't help
5) Using an Ethernet cable to the Phantom almost worked, but not consistently (and not after cable disconnected).

I had to revert to the Dialog in the end.
Has anyone had any success setting up & using a single Phantom on a password-protected WiFi network (without a Dialog) ??
