Many thanks -- I'll give it a shot. It has been gadget hell this week, and I have been hoping not to reflash anything. So far:
-- I did manage to get the iPhone working again, sort of, I think, just now.
-- Thought I'd resurrect my Xperia X running Sailfish. Had to run the SFOS upgrade twice. It lost everything. I had backups, but they didn't contain anything I wanted to save, such as VPN and ProtonMail stuff. SFOS ain't soup yet, imho.
-- The SFOS dual boot on the Gemini won't connect to wifi. Great. Connects fine in Debian. But I do not now nor have I ever had any phone stuff working under Debian, because it didn't exist last time I was using the Gemini, so I have no idea how to invoke it.
The iPhone debacle has made me realize the necessity of having at least two working cellular gadgets, so I'm hoping to get the Xperia X and Gemini totally updated and working and keeping them that way.
This stuff used to be more fun . . .
