Had AOKP and CM10 installed and each time I have to revert back to Stock or Kyan due to signal issues. Here is the situation, with any of the rom's build off the ucalem baseband that i have installed, I am always getting A LOT of loss of signal under Settings>battery>cell standby, But , when I have a stock or Kyan installed, there is no problem. I know from the nexus that this kind of stuff has to do with the RIL but yet I have not see anything here regarding this nor anyone else complain about the same thing. I am using bell SG3 with MVLLE8. Could the GB rom be reporting signal when in fact there is non, because a couple of times I have noticed that I had no signal but yet on the phone it was showing 2-3 bars then nothing. But using JB It just shows no signal and loads of time without signal. Would love ti get this figured out to be able to run AOPK or Cynaogen. I would flash the baseband, but I do not want any IMEI problems and also I have read that the ATT baseband does not support Dual Cell LTE here in Canada.

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.

Hi, I am canada, with fido/rogers and currently with the lastest 4.2.2 update and my signal is driving me crazy .
I've tried different radios using fastboot , but it is the same issue
it will be 5 bars than 3 than 0 than 1 than 2 etc
It can't hold a steady signal.
i've flashed the phone a few times to try to fix this issue with takju images and nothing
anyone else? is the phone bricked?
I found a rogers nandroid back up on these forums.. not sure if this will do anything
I'm on Bell and I have had a similar problem before. I wouldn't get good signal at all and the data speed was pathetic.
Try flashing the UILH1...it improves the signal a bit.
I have a GS3 that I have rooted and flashed to several different roms . Right now I'm running CM10 - 4.1.2. I am getting a 3g link icon but no data. Its getting super frustrating cuz every time it drops from h+ I lose all data and there's many places I SHOULD have service. Can someone PLEASE help me! I can't talk to T-Mobile without putting my phone back stock, and even then, I only have a 1 in 5 chance of someone whos not a moron answering the phone ...
It switches to 3G to save data and battery life, and to H+ when needed. If that's not the case, update your modem/radio firmware. http://forum.xda-developers.com/showthread.php?t=1860592 for modem firmware.
Time to update your 6 month old rom. And as suggested - your modem, too.
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'm getting really weak LTE and wifi signals.
I can't even use the mobile internet anymore.
When I go to status, it sometimes says Signal Strength is 0 dBm 99 asu. Other times it's -102 or -105db and 38asu.
I don't know the exact numbers, but on stock firmware, I used to get around 4 bars, but now I only get 0 or 1 on stock firmware.
I made a lot of mistakes trying to install Cyanogen mod. I originally started with 4.4.2 after installing it OTA. I was getting errors trying to flash Cyanogen mod and people were saying it had to do with an out of date bootloader. I kinda messed up in differentiating between the a bootloader and a modem and flashed an earlier modem which made my IMEI null and had no signal. I fixed this by flashing this 4.4.2 modem: http://forum.xda-developers.com/showthread.php?p=53627484
Now here's the problem. I didn't check to see if the signal was weak after flashing that. I flashed SlimKat, didn't like it, and then flashed aokp. This is when I finally noticed the signal was weak. I don't know if it started when I flashed aokp, but i doubt it did. I eventually flashed back to 4.4.2 using I747UCUFNE4 Stock Rooted Odex, and it still had a weak signal.
I then tried Cyanogen mod again and it flashed this time, but the signal was still weak. I then looked at the Android Version and it says 4.4.4 and the baseband version is I747UCUFNE4. Is this the problem? Because from what I'm reading, the baseband is meant for 4.4.2. I'm thinking that when I installed Slimkat, it upgraded my device to 4.4.4? But I don't know. Can anyone help me, please?
Okay, I have an update.
I tried using 3G and I'm getting great reception. Full bars and between -91 and -95db.
It seems there's issues when LTE is active.
Wifi is still terrible regardless.
edit:
Seems that when I call and talk when LTE is active, the reception shoots up. Text messages send and receive instantly.
The only problem is the slow LTE and poor wifi.
No idea if this will work for you, but it should be safe to try it.
In the T-Mobile Q&A forums sticky roll up thread is a link to a GPS fix (NV Rebuild). Follow the instructions there. It us primarily to solve GPS issues but I have seen it help with other problems similar to yours. It doesn't always help, but its certainly worth a shot.
Ill post a link to it in a few.
