Hey guys I need help,
I recently flashed loserskater's SRx3 TW based ROM for my i747 which went fine but I decided to revert back to an AOSP rom for overall smoothness. For those unfamiliar with SRx3 ROM, it comes with an AROMA installer which had one of the options indicating that if I wanted WiFi I had to use a specific kernel. So, naturally, I did. Well now after reverting back to an AOSP ROM, I'm noticing that LTE isn't connecting and that my signal continuously drops. Every 10 or so minutes my mobile signal will drop completely, not allowing me to make calls or texts. Also, when the mobile network is available I'm seeing H+ in my statusbar when normally I've been seeing LTE since I live in a really strong LTE network. I've checked the Mobile Networks section of settings and cannot figure out which one needs to be selected to re-enable LTE. HELP!
I have the same problem. A little less frequent than you though.

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.

hey gang i'm running the latest aokp task650 build on my S3 I747m. Everything works awesome, except i occasionally lose my data connection. I'll notice my connection status bars are gray, and typically a reboot will fix it. I'm sure going into airplane mode and back out from that would re-establish the connection too.
my APN is set correctly, i compared it to a friends nexus which is not rooted.
Right now i'm set as pda.bell.ca
I've flashed the latest bell modem file (that i'm aware of).
Anyone have any suggestions? i'm pretty new to all of this.. not sure what to do to troubleshoot.

I've been having problems lately when I have poor 4G (LTE) signal. My phone would rather hang around on the LTE network with little to no signal before it switches over to 3G. It's been doing this for a while on the Rogers network for me. I can see when I check the battery stats just how much time is spent without signal which is a lot. At work I get full bars 3G when at my desk but very poor 4G. The only thing causing me to loose signal is the poor transition back and forth between the two networks. Changing modems has absolutely no affect on this matter and I've put the APN's and network modes through the ringer with no change either. I've tried it all and nothing improved it. When I walk outside I immediately hit full bars 4G. Just when I'm inside my work and at home, I get poor lingering 4G. I wish the thresholds for when it switches over were better. I usually just turn off LTE all together which sucks but oh well.
I don't think we are the only people with this either. I've read grumblings about others noticing the same thing.
If curious, I'm running the latest CM10.1 nightly with Ktoonsez kernel on the Rogers network in Ottawa.
Interesting, that could very well cooincide with what i'm seeing. I tend to bounce from 4G to H+ or 3G, i wonder if it's trying to hang onto 4G.
Is there a way to force it to stay on 3G? that might be a good test
I was getting the same issue.
I did a factory reset and reinstalled my ROM plus GAPPs and the issue resolved itself.
I am using the latest modern right now and not my bell one. I think it's from a south American carrier, but bit 100% sure of the top of my head. But it is in the current modern thread

I rooted a T989. Flashed CyanogenMod 10.1. The phone call audio is very choppy. But people can hear me just fine. The data is also weird, its constantly rotating between 3g, H*, and DC. Sometimes changing every few seconds. On the stock ROM it was 4g all the time.
I've tried different kernels and radios. Im gonna try other roms now.
Can someone give me some advice?
For the call audio I suggest you to flash the new Jelly Bean radio: http://forum.xda-developers.com/showthread.php?t=2226835
Also the data is completely normal to do that. Stock ROM couldn't display what other data it's using at the current moment because it only has one image to display (which happens to be 4G
Hope this helped
I talked to a TMO support person a while back, and it was explained to me that TMO no longer has 3G. They only have 4G (which isn't a true 4G LTE network but rather a "sped-up" 3G network) and EDGE (2G). This is probably why we no longer see 3G on the stock TW ROM's. Also, many of the custom ROM's (other than a modified TW ROM) have versions that are used on AT&T and Verizon which still use 3G.
As far as the choppy voice, I'd try flashing the appropriate radio like the other person suggested.
Hope this sheds some light.
I have been using Beanstalk 4.4.4 for E980 for quite a while and my phone has been hehaving well. But lately I can't make or receive any phone calls if my network is on LTE. I know that voice is on 3G (HSPA) but when I am on LTE and I make a phone call, the signal switches to H and then it disconnects after I hear one ring. Also, when I receive a call and I am on LTE, once I hit answer, the call disconnects. I then did factory reset and also flashed other CM11 based roms such as Vanir and Blissstalk and the issue persists. I searched on the web and it seems to be an issue with CM11 users with ATT such as Nexus 5 and one plus one users. The rumor is that ATT is experimenting VoLTE in the northeast area (I live in NYC) and that there is a problem in CM11 in that situation. My wife's S4 doesn't have this problem with touchwiz version of kitkat. I can fix this problem by choosing 3G as my preferred network but then I lose LTE speed in data.
So are there any other people experiencing the same problem? Is there a CM fix that I could flash to avoid this problem?
try this
You try changing preferred network to 3G from LTE, and maybe that should fix the issue.
I'm using e980 with CM11 snapshot m11, and starts about a month ago, my phone starting to loose the connection to the mobile network regularly. It happens when ever I reboot the phone, and I have to reboot the phone 2-3 times before it's able to connect again. I switch to the cm11 nightly 3 days ago, as of right now I have been able to connect to the mobile network each time I reboot my device. I saw a few complaints regarding this issue on the cyanogenmod forum. Just thought I share the problem.
I flashed the Lollipop version of Liquid Smooth on my AT&T G3 and at first everything was working fine, 4G included. After a couple of days 4G disappeared. When this happened it didn't just go to 3G, it lost all data service completely. I originally figured it was the ROM and flashed back to the previous ROM I had using the TWRP backup I made beforehand. Same story, no data service. Figured maybe it was the modem so I flashed a working G3 modem on here, same story. I flashed to a different Lollipop ROM, Resurrection, to see if that fixed anything, nope. This is the ROM I currently have installed. At this point I went and look at the mobile network options and immediately noticed 1 issue, the preferred service was 3G and not LTE. I had an option to change it to LTE but when I actually select LTE it doesn't actually switch, it just stays on 3G.
The one good thing I managed to do was switch the APN to one that worked with 3G. The APN that was originally set was "pta", I can provide the actual APN information if that'll be useful but I figure most ROMs are going to have similarly named APNs. 3G works on at least 2 of the APNs listed for this ROM, "broadband" and "wap.cingular".
I called AT&T and determined that I my 4G service wasn't cut off; not that I really thought it was anyway as that wouldn't explain why I can't even select 4G as a network type. I'm kind of at a loss as to how I just randomly lost 4G access without actually making any changes to the firmware or OS of the phone. I'm also at a loss of how I can get it back.
And I am just sitting here with 3G with speed of 2 Mbps...
No one has any ideas or advice?
