Hello, I've been on CM 11 nightlies for the past few months and everything has been great but the last few days I'd had a little "R" above my signal status and it's been cuttting in and out. So I tried the *228 and it went through a programming sequence and finished. This seemed to change nothing so I returned to stock and fully updated. I now have no "R" over my signal status but I can no longer get 4G. I tried switching network mode,and disabling and reenabling moblile data. Please help
