[Q] Issues with LTE on CyanogenMod 10.2 - Sprint LG Optimus G

Hey there,
I hope someone can help me as I'm sort of at a loss. I just flashed Cyanogen Mod 10.2 and everything is working great, except this issue I have with LTE. When I am in a LTE coverage area, or places I would normally have LTE, instead of getting 4G or 3G, I get no data at all.
I've tried wiping the phone and reflashing the ROM. In my mobile network settings, I don't have an option to choose LTE/CDMA/EvDo or any other kind of setting either. Does anyone have any idea would cause this and how I would fix it? I would be very, very grateful even if I could set it to EvDo only so that I could get some data. Thank you, to whoever helps me.

From what I've been reading there are some issues with 4.3 and Sprint data. The powers that be are working on it so my advice is to find a working 4.3 or even 4.2 AOSP and keep reading. The brains will have this issue fixed soon I'm sure.

I'm having the same issue.
I never had a problem on the unofficial builds though. The toggle to switch between different CDMA modes is gone too.

Same Issue Here.

Same but I switched Roms , for know I'm just waiting for a fix

[Q] Only Getting 1g service with CyanogenMod

I just flashed Cyanogen RC2 and I am not able to get 3g. Where the 3g should be there is only a "1x". The data works but is incredibly slow, I asked a friend and he said that I might need to flash the new radio. Anyone have any other suggestions?
Thanks a bunch
What is your current radio?? When you flashed CM it comes with current one..

Are you in an area with a bad signal? At work when I'm not near a window my connection will sometimes drop to that level.
No I have full service and I did a speed test and I got 1 KB/s dload speed

I've had that happen and what I did was luck mobile data off, wait a bit, then enable it again.

This was happening to me to, on every rom. The other phone on my account was faster to...odd. So I called Sprint and they "refreshed my data services". Flawless now. Now its says 3g instead of 1x. Stoked

is there any risk involved in this? eg. can they tell I'm rooted/running a custom rom? sorry I'm kind of a noob when it comes to this stuff.
Also when I go to wireless settings there is no option for mobile data

Well don't mention it to them make sure you have a rom that has the option to update your prl, and profile. Because they'll want you to do it. Fare warning, they'll want you to update the firmware. I just went with it, but it didn't go through. It said "there is no system update". So it all worked out.
Sent from my PC36100 using XDA Premium App
This has been happening to me, too. I tried different radios, prl, etc.. with no changes. I even went back to a rooted 3.26 rom and let the phone update the firmware and everything it wanted to with no change in signal. The Sprint tech said everything looked fine on his end after having me update profile, prl, check for software and firmware upgrades. I can't remember what he called it but basically he reactivated my phone as a last step.
CM and mobile signal widget show 1x and when I go to ##debug# (on sense) and check EVDO engineering every field shows <failed>
When I get time I am going to go to Best Buy and hope their insurance works well.
That's weird because when I go to another rom like fresh my 3g works fine its just on cyanogen that my phone has this hiccup

[FIX]07-07-12-NEW Working GPS Fix and fix for WiFi, BT, & MMS on Verizon 4.1 ROMs

This 'fix' is old and is not be needed anymore since it was only used for GSM JB roms ported to CDMA TORO devices. Now that proper toro roms/sources are available, it will not 'fix' anything unless you are wanting to use an old rom.
This flashable .zip contains fixes for the some of the GSM settings used by those releasing Toro Jellybean ROMs. I haven't checked them all to see which ones are still using GSM settings, but these fixes shouldn't hurt anything if they are already using the correct files. I imagine they will eventually be incorporated just like the wifi fix was. Here is what is changed by this .zip:
/system/app/Mms.apk - correct uaprof for Verizon. Thanks to adrynalyne. Allows you to receive videos and play them. It converts to MMS instead of splitting at 160 characters! Just FYI. It can be fixed, but with jelly bean AOSP, I don't know if there is much point.Will replace any themed MMS you are using.
/system/etc/wifi/bcmdhd.cal - Fixes weak wifi signal
/system/vendor/firmware/bcm4330.hcd - Fixes weak BT signal and may help wifi as well.
DOWLOAD MD5: 552ca815433a88524ef00f738263c0dd
NEW Fix for gps - So far, all reports have been that it helps gps. Please make a backup of the files listed below or know how to recover to your rom's versions if something does not work. The .zip does not break your gps now . It contains the stock files from Verizon IMM76K 4.0.4 ROM.
/system/vendor/etc/sirfgps.conf - Using Verizon's version instead of GSM version.
/system/vendor/lib/hw/gps.omap4.so
/system/etc/gps.conf
/system/lib/lib_gsd4t.so
DOWNLOAD MD5: 70e63ce5a8d64416af5becf3f5d6bd6e
Please post with feedback if there are problems or it works .
As always, you are taking the risk of using these files. I use them and have no problems, but I can't guarantee everyone else's experience will be the same.
What's wrong with the WiFi on JellyBean? I've had no issues.

It works, but is weak. There have been many posts about it and it was also affecting me.

Yeah it was definitely much weaker. I'll try this when I go back to jellybean probably later today . Back on cm9 for now.

Works beautifully! Full WiFi, didn't even wipe caches.
Thanks for the confirmation guys. It looks like a configuration file and mentions verizon a few times and 5 ghz, etc. It had a lot of differences with the version included in the jellybean roms that have been released.
Worked great here. Excellent find.
The wifi was a deal breaker. I was just about to restore ics. Thanks a lot for this.

Evo 4g wifi won't connect.

Hey guys,
I'm using a EVO 4g with the Energy rom with Underworld kernel the problem is the wifi. It connect then disconnects right away. I've tried several fixes from here on the forum such as making sure wireless sleep policy was sent to never. I've flashed the kernel using the mount data trick and nothing works. If you guys know any fixes to help I'm willing to try. This is the first rom I really enjoy. Thanks.
Edit: Found out it wasn't just that rom. I think I saw somewhere to flash radios. Any advice?

Thus was your first rom you flashed on your phone? I was taught to update radios and wimax. Not sure where you would get that, but definitely stay in 4g threads. I'm going through the same thing I need to update mine & can't find a link...hmmm you find it let me know!

[Q] d2usc - 4G issues

Hey all, I'm at my wits end trying to figure out what's going on with my phone/service. First off I hope this is the correct forum since none of them officially address the US Cellular version of the S3.
So what is happening is that my device seems to only want to connect to 3G. I am running the latest nightly for CM 10.1. It all started last week while I was in the twin cities on data roaming for a few days. On my drive back to Wisconsin I notice I would go in and out of 4G service.. by the time I hit home I was on solid 3G service. This was last Friday. I knew there was some work going on the towers in the area as my brothers 4G service started working on Sprint. I just assumed it was something to do with that.
By Sunday and still on 3G, I called tech and they did everything under the sun to try to get me back on 4G to no avail. They ended up sending me a new phone. When the new phone arrived on Tuesday I did a factory reset on the old phone just to clear everything before sending it to them and I noticed it went back on to 4G. This was on the stock ROM, rooted still.
So I switched the phone over to the new one and sure as hell, comes up in 4G. I replaced the recovery and restored a backup I had.. phone pops up.. 3G. :crying:
I did a factory reset a few times and nothing.. still would only come up in 3G mode. I then restored a backup I had for the stock ROM and what do you know.. 4G. Flashed a fresh download of the stable 4 snapshot.. 3G.. then I did a factory reset and what do you know .. 4G.. reboot the phone.. back on 3G.. Tried AOKP.. 3G..factory reset.. 3G.. Back to CM 10.1 nightly.. 3G.. factory reset.. 4G.. reboot.. 3G.
I cannot figure out what the hell is going on.. it clearly isn't hardware as it's now happened on two phones. I thought it might have had to do with being on data roaming for a few days so I waited until the data billing cycle finished (the 6th) but no luck.
I'm at wits end.. I will try anything at this point to get it working again with CM/AOKP.. doesn't matter.. just want my 4G back!
Your phone does not have 4G, It has HPSA.
On AOSP/AOKP, your connection will show up as 3G until it's being used. Let's see some speedtests.
Don't go by what it says in the ststus bar. What does it say inder Settings > About Device > Mobile Network type?
Now go start a large download, like a rom or something. While its downloading check again and post what you see.

Speeds
Thanks for the quick responses guys..
First thing was my status bar was showing 4G for about a year.. it was just recently I started having the issue. I used to get about 20Mb/sec down and now I'm getting about 800Kb-1.5Mb. It's clearly much slower than it was.
And the network type is CDMA - EvDo rev A:6
Try going under Settings, More Settings, Mobile Networks, and try a different network mode.
Sent from my SGH-T999L using xda premium
Its selected as LTE/CDMA/EvDo. The only other option is CDMA/EvDO. I think it's set correctly.
What about Network Operators? Have you tried checking or trying a different one?
Sorry, I just don't know much about the usc model.
What is the model# btw.

Not sure what you mean by network operators but the CDMA subscription is set to RUIM/SIM (which it should be) and the System Select is on Automatic and not Home Only.
Model is SCH-R530U
Under mobile networks you can manually search for and then select an operator.
Judging by your model number, you will likely find more and better help and probably others with your phone in the Verizon forum. (Possibly Sprints, but most likely Verizon)

Thanks. I think I found the answer.. some code in CM 10.1 was causing the NV to lose it's information. A code change was put in to prevent that from happening.. I just need to go back to stock and flash back to CM.
Thanks for the help guys!

Everything I've read involves going back to stock, factory reset, and reflashing. Is there any way to resolve this without reverting to stock? Or is that the only way? - Does it need to be unrooted? And also, one thing I was curious about, I have a stock backup, would flashing that, and then reflashing to a current CM backup do anything, or does it need to be a clean flash?
I would go totally back to stock and start over. It wouldn't even take more than an hour to do everything.

Yup, if you're having problems, taking shortcuts often result in more problems and more time involved than just starting over clean.

I was having the same exact issue on CM10.1 RC5 -- called US Cellular and eliminated everything but CM causing the issue. Flashing back to an earlier version of CM, trying RC2 first.
Do you have the SCH-R530U? If so, see my quoted post below.

Verizon has their own separate forum and you can get to it from the main forum page. Go into q&a and use the search this forum searchbox.
I'll try to get the link in a bit. Bout to leave for a while though.

Went the revert to stock and reflash route. Issue is resolved. I did have to do it twice, as after the first reboot with RC5, I lost 4G again, skipped it and am running the 6-19 Nightly and have had no further issues! Thanks for your help. You guys are awesome!

[Q] 3.6.21 MIUIandroid Cell Connection

I'm running the Miui v5 rom and it works great in every way except my cellular connection is rather unstable. I have a T999L and I flashed the LTE modem after flashing this rom but it didn't seem to help.
Any advice? Thanks!
If its a rom issue, most likely you'd probably get more help posting in the thread.
Shouldve been no need to flash the modem unless you specifically did something to yours. The rom wouldn't have touched it.
You certain its not a network issue. Maybe they just started working on the tower nearby and it has nothing to do with the phone.
Call support to ask.
