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 seem to have signal issues on both ROM's. I'll give you guys a little background information.
I've used Fresh and Myn ROM's and always get perfect 3G coverage in my house and around town. Everytime I flash an AOSP rom I can't seem to connect to anything but 1X (if I'm lucky). When I was using the 2 previously mentioned Sense ROM's I'd have no issues with data. For the record I don't do a restore of my system data or apps when I flash because I prefer to download everything again to prevent FC's and other issues.
I've done a nandroid restore and updated PRL and Profile in a Sense ROM (2X) and then restored my AOSP ROM (ultimate droid) and that doesn't fix signal issues. My girlfriend has an Evo and she gets perfect signal on 3G (4G as well but she has it off) so it's not network related.
I downloaded the latest radio and pri from the development thread and flashed them in recovery. That didn't do anything at all and may have been a waste of time.
I then did these steps:
Dialed *#*#463+#*#*
Clicked on Phone Info
Turned off Radio (waited 1 min)
Turned radio back on
Ran ping test (failed because of no data signal). I can make/receive calls but nothing data related.
Is anyone having this issue? This has prevented me from fully enjoying AOSP ROM's and I don't know what the issue is. I'm using the latest PRL but could it be that my radio is broken? I would ready appreciate any help.
*** Update ***
I'm typing this thread on my phone and it's displaying 3G in full bars and then jumps to 1X full bars. It's kind of random but never steady. If anyone can please help me with this I'd appreciate it.
By the way I have an Airrave. Could that be the cause of my problems?

Same. i have this issue. although i dont get 1X. but i do however get spiking signal.
from what ive learned, the bars arent ur reception but how good ur connection is to the....satelites? aslong as u have 3G showing ur phone/internet SHOULD be working. although i would rather like to see all full bars where i normally would
i'm in a pretty high 4g signal area, but i love ultimate droid. i too have loopy 3g using cm6 or ultimate droid, would gladly give up my 4g to use either of these roms, but the 3g performance is way slower than on a sense rom. it's not just the bars, 3g on aosp is almost unusable, on sense roms, it works nicely
I solved my issue. The root of the problem is the Airave and how it connects with AOSP ROM's.
When I flash a Sense based ROM I don't have an issue with 3G and signal. I'm in a perfect 3G area by the way.
As soon as I disconnected the Airave last night my 3G signal came back with a vengeance. It hasn't left and is steady. I plugged in the Airave again and I saw my signal disappear and never come back. I could make/receive calls but no data access. I have the latest version of the Airave. Could someone (DEV) of an AOSP ROM investigate this issue. I knew it wasn't my phone because it would only happen in AOSP ROM's.

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 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.
DISREGARD:
I dirty flashed a different kernel and it fixed it.
Greetings. Quick question for anyone who is listening. I could not find an answer that suited me on this.
I recently flashed the G wizz jelly bean 4.1.2 rom and everything seems acceptable except for the fact that when it switches from 3G to 4G (which is quite often) my data rates are horrible. In fact, the mobile data speed is very slow all in all, even though it says 4g/3g. Not just that it's visually switching. I have tried switching between GSM WCDMA auto and just WCDMA and it does not make a difference. I am in Chicago and I've always had stellar 4G service. I should also mention that I have wpied and reflashed this rom a few times just to make sure that's not it. Several different downloads of the same ROM too.
Also, I am missing incoming calls as they are going straight to voicemail from time to time. I've never flashed a radio before (this uses the latest radio UVMC6) I was wondering if perhaps that's what I should do?
Any links for radios, flashing instructions, and others experiences would be greatly appreciated (and would save me more digging). Thanks for any help on this. Have a great day all!!!!
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...
