Ok so I have an unlocked LG Nitro HD with custom ROM (CM10) and it has a very weird problem. I've tried two different AT&T MVNO SIM cards (AirVoice and Consumer Cellular) both have the same issue. My data signal keeps changing from H to H+ and occasionally to 3G like every few seconds regardless of where I am using the phone even outside. I don't understand what the problem is. What could be the issue?

Are you able to use mobile data or are you just wondering why the icons go back and forth?

Data does work but it seems to drain the battery with the networks constantly switching and on occasion I get a "No Connection" screen on certain apps, I guess because if I open an app while its swapping networks the app cant connect. It's strange.

Yeah, constantly swapping networks will drain the battery.. what about your APN settings?

They are set up properly.
I had another odd problem, just a few minutes ago was texting someone and all of a sudden phone froze while vibrating then restarted! Don't know if that's a bug in CM10 or what, maybe the network swapping is as well.

Maybe make a backup of your CM10 and try flashing a different ROM not based on CM10.

I think this is the same issue that I recently fixed in quattrimus. I will try to get the fix included in the cm kernel soon. You might try my Rom to see if the fix works.

I tried installing CM9 and it appears to have fixed the problem, the phone doesn't try to connect to the H+ network anymore, only the H network and seems to stay on it so far. I did see it quickly go over to the 3G network but it doesn't appear to be causing any issues, it went right back to the H network. However, I really wish the CM10 ROM worked right, as CM9 is so old...

CM10 is snappy and oh so buttery smooth, I give you that. On another note, did you try any other CM10 variants? I'd give tdmcode's AOKP a spin. He says he might have fixed that problem you were talking about in his build.

I downloaded the CM10 ROM. It seems to behave slightly differently. It stays on H normally, but when I start to do something with data, it will go to H+ until the data loads, then go back to H. So far no disconnects, I'll keep you posted. Right now I have very limited data, I'm switching to T-Mobile as soon as UPS decides to deliver my SIM card (just found out they have a 1900MHz HSPA+ network in my area!) I'll be able to test it better then, but for now I'm trying to stick to wifi, especially since I wasted so much data tonight playing around with this stuff, lol.

Ditto... H and 3g are subsets of each other. Namely they can handle simultaneous voice and data 4G (h+) and lte can only handle data. So it switches back to H so you can receive and make calls plus it uses less battery. If you are on either 4G techs and receive a phone call while downloading it will automatically switch to H from h+ or lte, this is why. The only way you will never see this is on an AT&T rom where it only has 4G and lte icons.

H+ isn't a subset of 4G is it? I know that the CM's have separate icons for 3G/H, H+, 4G, and LTE.

That certainly is debatable but the US's largest carrier considers it to be, it behaves like 4g, H+ may not be as fast but it is 90%+ as fast in most markets small enough to not make a noticeable difference as far as people's perception and the technology behaves like LTE in a lot of respects, CM is international so it just conforms to International norms so that's why you get H+ AND 4G (LTE) designators.

SOS HELP
when I flashed AOKP's rom and using this rom almost half year
there has a crazy problem is about the T Mobile H+ signal
I remember that I used the stock rom showing the 4G icon everytime. and speed really fast.
but now I'm using the AOKP's rom when you using the H+ maybe just five minutes the network signal change to E(EDGE) or 3G
and network just stopped alittle while like 5-25 seconds then returned back to H+ or H
the problem make me crazy,
I searched in google sometimes but I didn't find any answer, maybe I just use wrong keyword on it.
so, anyone knows this issue? and how to solve that?
AOKP was released a 4g_signal.zip but it could not work right now on the android 4.2.2 ...
It happened every AOKP rom. when I flashed and use it
network signal is really instability.
It's not an issue.. the TMO S3 has only been supporting the HSPA+ bands at most and that is our 4G. When you flash an AOSP ROM it will display H+, which are the bands your on when your network is originally displayed as 4G on a stock ROM. H+ is displayed while data is being transferred. When no data is being transferred your data will bump down to UMTS or EDGE, which displays as your 3G, to conserve more battery. It's something you're gonna have to get used to on AOSP ROMs

Actually, no it does not jump down to Edge when there is no data pull (and you'll use MORE battery, because its search for the 4G network). When there is no data pull, it will display (on custom ROMs) as 3G. When it pulls data, it will show either H or H+. You already know that T-Mo network (exception of the LTE cities) has no difference between their 4G and 3G.
Now, you said that you're getting edge every once in a while. Try flashing a new radio. But, I'm confused, because you said you're trying to flash a 4G zip onto 4.2. There hasn't been a 4G zip even for a long time on 4.1. It won't work with most 4.1 ROMs, as the last time I saw a 4G zip it was for a specific updated of AOKP. Anyway, how long has the issue been going on since you started dipping down to Edge at certain times?

My mistake. That is what I was initially referring to. I should have said H+ displays AFTER data has been pulled. Thanks for clearing that up for me.

I've found that this phone's ability to transfer from 3G to 4G data is absurdly slow, if not completely useless. It also seems that it will never switch if there is data transfer in progress. The only reliable way to make it work is to airplane for about 10 seconds, then turn it back on. If there is 4G coverage, it will come back on immediately into 4G. Now that I think about it, the same thing seems to happen going from 1X to 3G as well.
Example of a common daily routine... When I leave work and walk outside, there is full strength 4G. But the phone will be sitting on 3G from when I was inside. It will not switch to 4G unless I airplane it first to cut it off and back on. The 3G data here is literally like a dialup 14.4 modem. So it will just sit there trying to sync or do whatever its doing until the cows come home. It will never change to the readily available 15mbs 4G data.
It is so bad, I had to make a tasker function to airplane, wait 12 seconds, and turn it back on. I made it a widget called "Reset 3G/4G".
Any way to fix this crap?
Sorry if I missed it but are you stock? Or are you rooted? Or are you rooted and running stock/custom ROM? If so, what ROM?

Rooted with the FreeGS3 ROM.
My EVO had the same behavior where it wouldn't switch from 1X to 3G if there was active data transfer. Which makes no sense. That's like not changing lanes on the highway because you'll have to look in the mirror first.

Maybe not, but the phone has to pause the connection, disconnect one radio, start up the other, wait for it to be on, connect using that radio, and then finally resume the data transfer.
I don't expect it to happen in a matter of seconds. But what you describe should not take 5, 10, 20 minutes to accomplish. It will not switch between 1x, 3g, and 4g so long as there is data transfer in progress.

True, but it may just be the apps blocking it. If theyre using it, the connection wont get dropped until it goes inactive, if I remember correctly
Here's why that makes no sense. App needs data connection. Phone in 1x with a 20kbps connection, trying to download music or photos. 3g or 4g is available. But instead of switching to it, it will just sit there until the app crashes, or tomorrow when it is done downloading.
Hmm... I'm on stock rooted MB1, and I'm also roaming at work, but there's a somewhat reliable LTE signal right outside the building, and as soon as I walk outside, I see my phone go from roaming, to not roaming, and then I see it switch to 4G in a matter of seconds. I don't need to turn on or off airplane mode or any sort of trick like that. Maybe it's ROM related? Custom kernel related? I'm not saying it is, I'm just listing possibilities.
Then again, I'm also not trying to download music or photos when I see I have a 1x connection, though my current ROM doesn't really tell me if I'm on 1x or not, so I just don't do anything network intensive when in low connection areas.
I just changed some settings in the ##DATA# menu. We'll see if that helps.
When I am on the Network Mode LTE/CDMA/EVDO AND on 4g, my data works as intended, download and upload works. However, if I am still on LTE and only have 3g service...I get ZERO upload data. This is why MMS doesn't send and other things (Instagram, Snapchat).
To get these things to send, I got to set my Network Mode to just CDMA/EVDO Auto. The downside to this is that 4g will never get picked up when available.
If anybody knows how to fix this so that my data uploads when I'm 3g but on the LTE/CDMA/Evdo network mode that would be great!!!!
I am running the Carbon 5/10 nightly but I believe this is a common AOSP issue.
Thanks!!!

Which modem are you on?
Once you can identify the baseband version try different modems besides your current one and see if it makes any difference for you. I'm sorry it took so long for anyone to respond to this..

Unfortunately, this did not work. I'm wondering if this is an APN issue, although I don't really know what I'm talking about.
As you can see from the screenies...3g upload speed is non-existant when on the LTE network mode.
Edit: 1st screenie is on LTE. The 2nd is on CDMA/Evdo Auto.
What are you talking about 3g on lte network mode. 3g is 3g. LTE is 4g two completely different things. If you have LTE in your area your device would connect and say 4g. If not it will connect to only 3g. If you are on a stock rom you might only be connected to 1x speed but your phone will display 3g. Only custom roms will break it down to actually show if you are on 1x connection.
If you are on a custom rom then that may be your problem if you do have lte in your area, even more so if you are on aosp type rom. They have issues handling the exchange between 4g and 3g. I pretty much bet that's what it is an rom issue handling the exchange.

Under settings - mobile networks - network modes. The LTE mode is selected. In areas where 4g is not available and only 3g is...upload data does not work. However, if just the CDMA/EVDO auto is selected under mobile networks (LTE NOT SELECTED) data upload works fine.

What Rom are you on? Never mind, just read your on Carbon. This is a common issue with aosp roms. You should leave it always in cdma/lte/evdo never change from there. Set it to that and reboot. Use the toggle for 4g to turn 4g on or off.
But beltway to assure yourself that it is a rom issue is create a nandroid, then flash a TW rom and test the handling between 3g and 4g, and your data.

I am on LiquidSmooth v2.4 official. However this happens on the past few AOSP roms i have tried.
Back to what you said, maybe the handoff from 4g to 3g is just not working with data upload properly.
Wow I must say thanks for the toggle idea. Beats the heck out of going into mobile settings and switching modes every time I want to send an MMS.

Correct, just do yourself a favor in order to eliminate a hardware issue. Make the nandroid of your current set up. Clean flash a TW rom anyone and check the handoffs if it works property it's a rom issue if you still have problems it could be the device itself. It takes less than 5 minutes to test you don't have to set everything up just flash log in with Google account and check.

Hi, it's been a while since I posted on the forums. I've had a problem with this for a while now, but never bothered to ask you all. i don't get certain types of signal with the stock rom and aosp roms. For stock, I get 4g data, and I am able to make calls while roaming but not while I am on regular 1x (connects but I can't use it). Also, signal is iffy, sometimes it connects/randomly disconnects. For aosp, I get almost no signal, only roaming. I think that I didn't mess up my efs folder, my imei is still the same as the DEX on the back of my phone. Do you guys know what is wrong or how to fix this? I want to be able to use my phone again...
What modem are you on? Firmware or ROM? I'm using NE2 with rwilco's stock ROM and a GSM sph-l900 with t-mobile... I get 3G and 4G (hsdpa+)... before I use to get lte/3g/1x and I use roam control when I'm in an area where I know I don't have a good signal...
