I tried reflashing CM 7.1 first, then WiFi Calling WITHOUT Google Apps. Same thing, no service. Baseband version was then reported as <unknown>. Reflashed the ROM and Google Apps, and now the radio reports 5.12.00.08, which is acceptable according to this link (although whether it is required or not is debatable).
In "Popular Downloads" on Unforgiven512's website, there are two packages available. I used the newer one.
I tried removing the extras in Titanium Backup, but I couldn't figure out exactly what I needed to remove. Can you guys hold my hand for a couple minutes and show me exactly what needs to go? I'd really like to post a definitive fix for this issue to remove the confusion.
