Hi all
Sorry if this question has been answered, I've had a good search through the forums and can't seem to find an answer.
My problem is as follows. Completely randomly but quite frequently my phone will lose signal, the signal bars remain full but I am not able to make/recieve calls, send/recieve messages or send/recieve any data for anywhere between 30 seconds to a few minutes, then just as suddenly all will start to work again. It occurs in different locations so I dont think it's a issue with the tower I'm currently on. When it occurs with data I have noticed that the 3G symbol will not change to H.
I have tried several different radio's and roms including 1.5, 2.1 and 2.2 roms, currently running cyanogenmod 1.4.3 (froyo) but as I say this occurs across various roms and versions of android. I have also tried setting the region in the Info(*#*#4636#*#*)-Phone Information menu to Automatic, Aus1 and Aus2 with no improvement as well as enabling and disabling cyphering (no clue what that does but thought it worth a try)
Can anyone shed any light on this at all? It's driving me crazy!
Thanks
For the 2nd time w/ axura i have lost data connection. I flashed this rom on friday and lost my connection on saturday, reflashed saturday then lost again on today. I've reflashed for the last time. I tried turning on/off airplane mode, changing network modes, rebooting. Nothing seems to work except reflashing. I really hate this because I love this rom, but if happens again I'm going to have to try a different another rom. Does anyone have any ideas why this is happening? Has anyone else had this problem?
yes this has happen to me twice as well. Do you happen to have the wifi calling app installed?
I don't think so. Is that something that I would have to add. I didn't add anything extra or change the kernel. Are you only getting a day out of it before you lose the data? I can connect to wifi when I want.
Here is what happen to me. I was using Eugene's unofficial Odin froyo and everything was well except for the browser was laggy all the time. I decided to flash master's rom because it supported wifi calling and at home with wifi everything worked well, but when i left my house yesterday for work I could not get data or voice. The bars and the 3g icon were there but did not work. I flashed the rom again on the way to work and everything was good. Today we left to do some stuff and the same thing happen, I tried to go to into flight mode but it would not go back normal. In addition I installed the wifi calling app that lets you make calls over wifi and there is an option for preffered connection method, I had it set to wifi only instead of wifi and 3g. I changed that option and from there everything was working as it should. I also noticed that its set to Gsm instead of auto Gsm/wcdma and it wont let me change it. I don't know if that has to do with anything. So I am back at home right now and i don't get any service so i cant test to see if it has anything to do with wifi to 3g transfer.
I am really bummed because i like this rom alot, it has all the bells and whistles and its great on battery.
If this continues I think I am gonna odin back to stock then start over. It might also have something to do with my titanium back up.
Maybe it's a Georgia thing. lol. When I lose it the task bar only shows the bars, nothing else ( no 3g or edge). I'm with you though this is a great rom. If it happens again I may go back to stock and wait for the official froyo. Not really sure what else to do.
Is it okay to install the JI2 or JI6 modems on a Froyo ROM? If so, you could give it a try. Fortunately, people have created flashable .zip's for both.
This happened to me also. I lost my data and voice connection. Checked and saw that airplane mode was on and no matter how much I unchecked it, it still stayed on airplane mode. I reboot my phone, and reboot and reboot the **** out of it and now its been working just fine for more than a day now.
I don't know if it is ok to install those on a rom. My knowledge on that kind of stuff is very limited to say the least. This is my first rom. If anyone knows about this, your help would be greatly appreciated.

JI2 and JI6 are 2.2 capable.

Check the download section. Also I can't confirm but from what I remember the JI2 + JI6 both have the bug where switching radio modes (edge / 3g) will force you to do the flight mode reset.
I also had this issue because it always happens when I stream music while driving.
About not being able to get out of airplane mode. I don't know if it was just because I was tired, but every time I used the reboot feature instead of powering down, it would never get out of airplane mode. So, when I looked carefully, reboot, airplane mode, and another option was greyed out while power down wasn't. I found it strange, but whatever. I fully powered down and then turned it on. Airplane was now off.
I was on Axura 2.0.4 and because of this issue, I switched back to Obsidian. It could possibly be the modem, but at the time I didn't check it. Just report it to Master and hopefully the bug can be found.
Hey guys i got a problem.
After flashing my phone normally with Odin like usual all of a sudden data connection aint working anymore. I works fine with wifi, but not without.
It shows 3G/H signal in the status bar, and i see the upload arrow is blinking so it is sending data, but not receiving anything.
I tried googling it, tried flashing various different roms that worked before and original firmware, but nothing helps so far.
I checked the provider info in the phone, and its all correct.
Kinda lost here, hope someone has an idea how to fix it
thx in advance
nobody? i tried everything so far and dont even know why its not working anymore
It's going to be difficult to get much help here because I don.t think most developers have had time yet to get into the innards of the A501. Have you tried flashing back to the original stock ROM? You did back it up before you flashed it with a custom one right?

No nandroid backup, only titanium backup since i never had problems before.
I tried flashing all kind of original firmware now, KH1-3, even older ones, the latest. tried all custom roms that worked fine before.
Tried different sim cards, readded the APN settings etc.
Found out now that 2G is working, but as soon as i switch to 3G etc it shows the signal for that, i see upload but no download, so it basicly stops working.

(Instead of quick reply, i hit thanks first!)
Dial *#301279#. If it doesn't work, dial *#*#301279#*#*
Select 2nd option (Change HSPA revision or whatever).
Then select 3rd option (Release 6).
Restart.
Also, check your APN settings.
Use an app called Tweakker which will configure your apn if u dont know exact settings.
thanks for the quick replies guys.
so i did play with the codes today already, the option you stated i tried but sadly it didnt change anything.
HOWEVER i did choose disable HDSPA completly now, so i am on 3G only and guess what, now it works!!
Speeds are not what they used to be at this location, but that might be due to my data limit so i have to check.
With other codes i found out that while being on H/H+ phone didnt download 1 byte, so i have to wonder why.
With 3G it is working now, but what could the cause be. Used to flash quite often and it always worked, so not sure if thats even related to my problem atm.
Any idea what might cause the H stuff not working at all? I read about the SII getting stuck on H+ etc. before, but all the tricks with rebooting or toggling flight mode etc. didnt work for me
so far, thanks a lot!
Try different modems. Depending on ur location and service provider, atleast one should work right. I'm using KI3 modem without problems.

modem depending on location and provider?
i tried several modems from the original firmware thread under development. they all used to work fine before, now they dont. KI3, KI8, KH3 etc. all nothing :/
Hmm strange. May be you should delete all apns, and configure a new one for your provider.
Also give KG5 and KG2 a try.
i am having a SGS2 with KI3 and sensation rom 1.7 with kernel siyah 2.0. after doing this i am also facing a problem with my data connection. it works but its on / off.
can you suggest come remedies like now please .............
Hi,
After flashing a build of CM11 back in February, I've had problems with the data-connection (2G/3G/H, etc.). It works when starting the phone, but suddenly it just dies. It looks like it's working, but no data seems to be transferred. I have to turn data off for a minute or five, and back on. The it usually works for a while again, until it dies...again..
I've fullwiped (except SDcard and internal SDcard), and tried several modems. Then I went from CM back to Ultima ROM (based on stock Samsung), and used it for a couple of days. Data worked perfectly. Thinking it solved the problem, I tried Omni again, after wiping/formatting data, system, cache and Dalvik. Installed it, data seems to work, but after a few hours, it just dies again.. The signal icon still has the H+ connection, etc, but I can't use it. Just like it's offline.
Any ideas?
Use GSM Network

This is EXACTLY what happened with me. I don't use WCDMA Network now. Use GSM Network (EDGE). I hope it'll get fixed in Android 4.4.4 and we'll be able to use 3G again..
On GSM Network, I never faced such a problem even on CM ROMs.
The weird thing was that I had no problems using 4.4.x version of CM of the January builds with 3G. They worked great when it came to data. And it doesn't seem to be a common problem, as I haven't read about more than one or two users before me. Switching to 2G/Edge does seem to work. Might be a coincidence, but I'm going to leave it on 2G for a while, just to check.
Either way I would love to use 3G on AOSP. If not, I would have to go back to stock Samsung..
First I thought maybe it happened because of damaged IMEI .. But 2G works! So it's not..
weird problem.. It isn't like the phone says it's not connected to network.

I tried Intelli3G with Xposed, but 3G didn't help either, so I forced it to 2G (within Intelli3G). That seemed to work. After an hour or two (still working), I tried (for the fun of it, since I hate 2G) to press *#*#4636#*#* and under Phone Information, I changed to WCDMA preferred. Data has been working stable since last evening. Might be a coincidence, but I'm crossing my fingers. I've disabled Intelli3G as well. Haven't rebooted after disabling it though. I'm afraid it wold stop working.
Restart seemed to work ok. For some reason it was set to 2G (GSM) only. I changed that to WCDMA preferred again. Seemed to work. I then enabled Wifi to update som apps, and then disabled Wifi. It reconnected to 3G, but now the connection is dead again.
If I go from 3G to Wifi and back to 3G, the connection seems to die. I open Intelli3G, change the mode to WCDMA/GSM auto or any other so data disconnects, and change it back to WCDMA preferred. Data now working. Don't know if I should stop using Wifi at the moment (if it's the transition between Wifi and data that stops it), or go back to stock 4.3, where it seems to be working as it should.
At least I have an (almost) unlimited dataplan, so data on 3G and no wifi is probably best all over, even though wifi at work and home is a lot faster than 3G..
Data has been stable on 2G/3G since yesterday. I've turned off Wifi completely. It's not a solution by a long shot, but at least I know data is working stable (so far) as long as Wifi is off.
phone works great then reboot no mobile data have to keep turning data off and on and refreshing network I get a LTE! symbol. The signal goose up and down very fast. Is this a bug in the rom, Or a bad APN setting? after like 15-20 mins I get it working. I really want to run cm13 or android 6 whats a good stable rom or should I just flash back to factory?
Thanks

I have same problem on LG G2 with CM 13. I have exclamation icon on carrier signal. I tried everything
Turn on/off airplane mode Change mobile networks settings (change same as original firmware)
Still same. Must be fix
https://www.reddit.com/r/cyanogenmod/comments/3xm0mo/mobile_data_not_working_cm13/
gess it may be a problem with cm13 guess I will try to flash a different ROM
Im using this ROM, http://forum.xda-developers.com/oneplus-x/development/rom-temasek-s-unofficial-cm-13-t3304423
fully working, no data problem
only one known BUG, but its related to radio not to any ROM. When you loosing you signal frequently in your area, mobile data stops working and you have to turn airplane mode on/off. Solution to this is to use 2G only.
check your APN settings
Check your apn settings. There are probably wrong. Check your carriers website and the apn settings that were included in your rom. I had this problem with a cm based rom and with salt / orange in Switzerland
I have this problem aswell, everytime I hit the switch to turn on the data and I go back to my home screen, it just switches off. I have this with temasek's CM and the official CM patch aswell, I checked my APN settings and they are fine...
I also noticed that in the settings menu for Data usage the date where it changes doesn't show up, there is only a little arrow for the drop down menu but touching it doesn't do anything and it doesn't display a date aswell.
I have a similar issue, basically I have absolutely no data both on the Temasek and the standard cm13, 17/05 version. With clean flash and dirty flash.
Checked APN settings, tried to play with airplane mode and SIM card settings, force 3g instead of LTE, but nothing so far, so I'm also very interested in a fix.
I'll try to update to latest nightly to see if that helps... Carrier is Free in France.
Thanks,
