4G/LTE Problem with CM 10.2

cigator said:

Hoping to find some help here. I have searched the web and no definitive answer. I was running CM 10.1.3 on my Razr Maxx for a long while. Just flashed to CM 10.2 with Android 4.3. Since flashing, I no longer get a 4g icon for my signal, I get LTE. In addiiton, the LTE signal fades in and out and most times the bars are white which I have found out means I'm not synced with Google servers. I have played with the APN options to no avail. Is anyone familiar with this problem? Is there a fix? Thanks for any help you can provide.

I did a fresh root and install of safestrap 3.65 and CM10.2 stable on my xt912 for verizon. I also have the same issue. Coming from the stock rom I now get terrible service and if I change the network to anything with LTE (global or cdma/evdo +LTE) I cannot send or receive picture messages. I tried to change the APN and it makes no difference. Lastly if I try to edit the APN it will disappear from the list.

I stopped editting the apn because when I limit the service to cdma/evdo I can send and recieve picture messages, but I get no LTE/4g service.

I am starting to wonder if the rom slot 1 conflicts somehow with the original stock rom.

After installing safestrap I did a factory wipe (not advanced) and installed the rom and gapps.

If there is something I am missing please do inform me. Perhaps the op's issue is the same.

You need to update to kitkat stock messaging app & ...

Yes I did that. That is why I can send them when on cdma/evdo. It has never worked with global or any lte network.

Thinking of trying cm11m4 on rom slot 2 to see if that is better...

It is fine to get mms to send on CDMA. If the phone is on a 4G or LTE antenna it doesn't work for me. Also, this does not solve the issue of the APN's disappearing. This is a fix for some cases not a solution.

In my case I created Rom slot #2 and installed CM11 M4 snapshot and all is working there. LTE works fine, MMS sends... I didn't find any immediate other issues in the 2 hrs I played with it last night. Looks like this may be the daily driver for a while until CM11 stable comes out.

I still have 10.2 available in Rom slot #1 so I can test if anyone cares to find the real "solution"

I would not have thought this would be an issue on a stable build either.
With kitkat in development, CM10.2 will be abandoned.
Probably will try CM11 nightly myself in about a month unless there is another snapshot or even stable build by then.
