Default [Q] CM11 - STRANGE data problem

So I've been having this problem for several months now...

1. When I go into the testing menu (*#*#4636#*#*) it currently says LTE/CDMA (auto PRL)

a. When I switch on LTE from the notification pulldown I cannot get a data signal, however voice calls still work. I can leave searching for 20+ mins. for a signal, it never finds one.

b. When I switch off LTE I am able to get a 3g data connection, and voice calls continue to work

2. When I go into the testing menu (*#*#4636#*#*) and switch to "LTE Only" I am able to get a 4g signal, but no voice calls or sms (as expected),.

I've tried a the 3 most recent radio's. I'e gotten 2 new SIM cards. I've tried clean installs of CM. I haven't tried other ROM's, although I'd be open to suggestions if people have no data issues (I like CM a lot though).

Any one else experiencing anything like this?
Thanks for your help!

I've experienced the same problem on newer nightlies, M5 and M6. I formatted /data, /cache, and /system, then install M4. data + voice work right away.

Try switching to CM11 M4.

I upgraded to M6 (then tried M5 after it didn't work) due to bluetooth issues on M4; specifically, none of the advanced features of bluetooth, such as the ability to sync my text/voicemail notifications and display artist/title info on my dash, didn't work with my car. But I'd rather have reliable mobile data service on M4 with crappy bluetooth support than unusable mobile data service on M6 with great bluetooth support.

Edit: this is a toroplus phone on Sprint, btw.
