I bought my 1+ from the website and it was working on Wind's network (1700/2100 MHz) until just now. I flashed CM12 nightly and realized I couldn't make phone calls (data and WiFi were fine). So I followed a thread on XDA and changed my band to USA/Europe (*#*#4636#*#*), but none of these have 1700 or 2100 selected. Now, my phone won't detect Wind's network in Settings > Network Operators and data/SMS/voice won't work.

I tried many different modems (CM12, 44S, etc.) but it only shows Bell, Telus, Rogers on the network scan. Any ideas on how to get Wind back?
