So, as the title suggests, I have a Sprint Samsung Galaxy Nexus L700 running Slimkat with Android 4.4.2 build 4 official. I think there's an update to that rom, but at this point I don't think the rom has anything to do with the issue. All roms have the issue.
So the issue in question. Sprint rolled out LTE 4G in my area but my nexus never gets it. I know we have 4g because my Galaxy Tab 3 picks it up all the time. When I look at the tab, the network is listed as LTE:14. However, no matter what I try, the nexus will only ever pick up CDMA - EvDo rev A. This is a 4G phone and I'm using the GJ04 LTE/CDMA radios, but I never get 4g. I get 3G just fine. For whatever reason, it's like the LTE radio on this nexus never bothers to activate.
What i've tried to fix this:
1. Different radios. I've tried them all, from FC02 to GJ04.
2. Different roms. Same issue on all roms. Doesn't appear to be a custom rom issue.
3. Doing the data settings to LTE only. This doesn't stick, it just goes back to CDMA. I'm told this is by design due to 4g being data only mode.
I don't know what else I can try. Sprint's only answer is to blame it on the custom rom. Which I can't necessarily blame them for, it did void my warranty, but even with the stock rom I still get no LTE.
