Yesterday I flashed the newest CyanogenMod 11 nightly, and I am now unable to call, text, or use mobile data. When I go to About Phone ->Status and check my phone number, it says my phone number is 000-000-0626. I am able to connect to Sprint, however. I tried going back to CyanogenMod 10.2 stable, but the problem still exists. I also tried going back to the stock ROM, and the problem still exists. I looked for hours online, but could not find anything to fix my problem.
