Flashed CM and lost Mobile Data/Phone. Nandroid to Sense doesn't fix it.
I have a rooted HTC One, and I've been running Viper Rom for months. I recently tried to flash the Stable CM10.1.3. When it booted I had lost Phone/Mobile Data. I tried to restore the data, but nothing worked, so I nandroid'd back to Sense.
I still don't have data. My 4G works, but I cannot make calls or text.
Am I correct in understanding that I need to achieve S-Off and flash a radio? Ideally, I'd like to have CM10.1 running on my device with data back. How can I achieve this?
