[Q] slow data on LTE

just got back to a galaxy nexus and man it feels so natural lol
I had an update to 4.2.1 and since then i noticed that my LTE is extremely slow now. Mind you Im connected to an LTE repeater and my sprint coworkers are pulling in some amazing number but mine cant pull more than .4 megs.
Ive updated profile, prl and hard reset. (im on the sprint nexus btw)
Im not rooted but i wonder if i should root and just push a modified build.prop
any help will be appreciated.

is there anything i can add to the build.prop that can improve data speeds?
ive been ablt to do it on gsm android phones, but im not sure if i can do it on a cdma device

Try different radios

besides that are there any build.prop mods i can do for data? im not sure if that works on a cdma device

FH05 radios work far better for me than the GA02 radios. My nexus won't stay connected to 4g on ga02 radios but it's stable on fh05. You may want to try asking in the sprint nexus developer section if no one can help you here

[Q] Help with RADIOS!!!

I have a rooted Galaxy Nexus with Sprint running ParanoidAndriod 3.55. I think my radios are older and I need to update them. My baseband version shows L700.05 V.FC12 / L700.FC12 which I understand thier are newing radios out to download. I am having issues with signal lose making phone calls and what not. I live in a area where Sprint should have no issues with service wihich I have never had before. I am hoping that updating my Radios will help. Can someone please tell me which one are the newest and the best way to install them. Thanks.

Thanks for the info. I know I posted in the wrong thread I just dont think I can delete it. Thanks again.

I live in Overland Park, KS where Sprints headquarters are. Sadly I get crap signal no matter where I am even with most recent radios.

[Q] Stopped getting 4G after CM flash

i unlocked a sgh-i747 sgs3 for use on tmobile. when i was stock, i could get 4G and Edge only. After a suggestion, i updated my phone and it connected to all manner of 4G and HSPA networks.
i decided that i wasnt happy with the ROM and upgraded to CM 10.1.2-d2att by means of CWM v6.0.3.1.
after getting this happily flashed, i loaded CM and am now stuck in 3g.
any ideas???

I may be wrong, so don't try it without confirmation, but if you don't touch the radios, don't you need the t-mobile roms rather than the at&t ones? I suspect the problem using an at&t Rom is your apn's are messed up. Also check the order your networks try.

can you elaborate on this? i know what a radio is, but i don't know if i follow you. as someone pretty new to all this, i feel that i did mess with the radio in order to get the AT&T phone, before i installed CM, to connect properly to the 3G signals.

In recovery you can flash modems and baseband. These are specific to the hardware in your phone. You should only flash ones specific to your model number. However the Roms are basically the same between different versions of the phone but with minor changes (at least between t mobile and at&t). There was a thread around explaining how to use a t mobile Rom on an at&t phone.

i tried to straight flash the tmobile rom and the little android guy died

meh... im in a bad place. i can't flash the CM i want because apparently the bootloader that fixes the 3G issue for me is based on ICS. if i update the bootloader so i can get the good CM, i guess i lose the fix... right now, i've reverted to the touchwiz that comes with the fix i talked about in my OP and 4G works properly again.
rock and a hard place.

Am glad you got something working. Can you sell that gs3 and get the T Mob version? If it were me, I'd probably stick with a touch wiz version for a while.
I'll try and read up some tomorrow.

heh, i just bought it. got it this morning from the post office! it was the cheapest one i could get given certain circumstances. you're right, it would be so much easier to just have the official tmobile version.
i have it back in CM now, but it's CM10.0.*. android 4.1 i think. and i'm getting HSPA+ with it. my biggest issue is that 3G fix... it sticks me on a ICS bootloader and that holds back the CM version from being anything 10.1.*. but at least i'm running CM now, even if it's not 4.2.

[Q] Samsung Galaxy Nexus Sprint L700

So, I thought I would ask here. I can't find a lot of information on the problem. There are sites that have contradicting information in google results, but mostly, nothing consistent. Hoping at least here I can get a why or a how to fix it.
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.
Any ideas?

Well for sure one thing is to flash the stock rom and see if you get the lte connections.
second, try someone else sim and see if that fixes the issue.

Sprint Galaxy Nexus getting no 4g inside coverage area
I am having the same issue as the first post and have tried all of the same troubleshooting tactics with no prevail. I am currently running LiquidSmooth v3.1 4.4.4 KK baseband GJ04. I have contacted sprint and they are of absolutely zero help. Not only am I having 4g connection issues but I can barely receive 3g. I am located literally in what sprint considers one of their best 4g coverage areas in my area yet haven't been able to connect once. Please any help or insight as to a solution would be greatly appreciated.

Moved.
I personally use the 56xxx series PRL on my Sprint devices, it's a Corporate PRL and allows you to roam on Verizon 3G.
I'm not 100% sure if a Verizon PRL will work on a Sprint device, unless it's been modified in some way, but that's above my pay grade lol.
Here is also a good thread for finding different PRL's
