Lost Mobile Network (Data) on CM 2.2 - Hero CDMA General

I went on vacation last week, and woke up one morning to find that my Data connection was lost.
Voice still works perfectly, however no 3G, 1x or EDGE.
In the Phone status, it says "Mobile Network State: Disconnected".
I've tried turning the data on and off. Turning on Airplane Mode, Turning it off, Rebooting, and every other combination I could think of.
It's running CyanogenMode 6.0.0-080710-VANILLA
Baseband 2.42.02.10.29 (Just updated)
I have no problem flashing back to stock or similar, but I just thought I'd check if anyone has had a similar problem before I call Sprint or lose all my stuff.

Switch over to a sense ROM and update your profile. Worked for me.

I'll try that now.
Thanks

Did this work? I'm having the same problem. I was running CyanogenMod-6.1.0-RC1 and used wireless tethering. I turned off the wireless tethering and I've lost my 3G connection. I tried flashing the rom again with no luck and now I've even restored back to the original backup before I flashed with no luck.
If I can't find anything to fix this, I'm going to unroot and take the phone back before my warranty is up in 6 days.
Thanks,
Josh

MyTouch not showing Edge/3G icon

I woke up this morning and my phone is not showing an E or 3G or even a G for that matter
At the lock screen it shows I'm registered on T-mobile network. I can place and receive calls/texts.
I can't access anything that uses data though. I've tried rebooting the phone and doing a battery pull.
This has me baffled.
This happened to me today too. I wasn't using any data so I thought nothing of it till a bit later when I restarted my phone and when it booted back up 3G came back on and the icon came back.
My theory is that the phone only tries to reconnect every once in a while to the Internet when the service goes down so it probably was just down when you tried before.
Can anyone confirm that this was a system wide Internet outage? Or regional? (Philly for me here)
Still no icons for me. i'm in alabama.
In my haste to figure it out I did a factory wipe/reset hoping to solve the problem. It didn't help. Now I can't sign into my gmail because it can't connect.
Still looking for help here if anyone can offer any
try checking your apns
Check your apns under settings>mobile networks> apns
Should say internet2.voicestream.com as on of the apns. Do a Google search to find the correct alms if you don't have T-Mobile
Hey, thanks for trying to help but it came back on its own just now. After i ended a call the E flashed for a second and then 3G popped back up and has been fine ever since. To bad I had to go all day without my data.
oh, and as far as I know my APN has always been epc.tmobile.com it works fine.
I am experiencing the same problem in France. Apparently it comes from the cyanogen mode (wether it is version 404, 418 or 4.10.1). When I install it everything's fine for a few hours and then the E/G/3G disappears most of the time, just showing (less than 1sec) every now and then. I can call, text but no mms/web/market dl ...
I tried a backup, wipe and reboot. Everything works, but a few hours later ...
If I restore the backup it still won't get 3G...
Is the only answer to wait and see ?
Great, I just installed the "CME_DHD2_COMPACT_v1.6_CWM_ODEX_RAM" ROM and I do not have any APN entry at all.

Bell Galaxy S2 On Telus Network - Network Drops Every 10 Min

Hey everyone,
Had the Galaxy S2 since Saturday, unlocked the device, everything was working great. Out of no where, yesterday the phone still shows the H+ logo and full signal, yet i cannot send, receive text messages, initiate a data connection or make/receive phone calls.
In order to get all that ability back, you either have to 1) reboot the device, or 2) turn airplane mode on then off.
This only works for roughly 10 minutes before it all happens all over again.
I tried swithing to WCDMA only, but issue still persists, even tried some menu codes I found on another thread to disable H+ but the same thing happens.
This is currently happening on the bell shipped rom with no root or anything of the sort.
Has anyone experienced this?
I've searched for hours but can only really find complaints of data connection loss only. In my case it's everything. Data / SMS / Cell
Any help would be greatly appreciated.
I feel your pain, even though I have an XEU unlocked GS2, I've updated it with every update from kies hoping the issue would resolve.
Even with the latest KF3 update the issue persisted, however the phone could be used on Rogers with no issues, on Telus data drops constantly.
Disabling fast dormancy didn't do much to help.
However since updating the phone to KG3 2.3.4 yesterday I have not had the issue happen again. For the first time since I got the phone it no longer drops the data connection on Telus.

Thanks for the quick response. Was it only your data that disconnected, or everything else?
Also, may you please link me to the update? I suppose I could use that as a last ditch effort before exchanging the device before its too late.
My issue has changed over the past couple months, originally the phone would report that it dropped the network and when it came back data wouldn't work until airplane off then on or a reboot.
Lately things seemed fine with occasional data drops until yesterday, when it had full signal but I couldn't use data, sms or make a call. It was basically a paper weight until I updated it. The link to the file which has everything you need to update from samfirmware.com is below.
http://hotfile.com/dl/124839941/a17b394/I9100XXKG3.rar.html
*edit - I'd make sure you have a back-up of your current firmware in case you need to flash back and return the phone.
I have the exact same problem. Bought a bell gs2 unlocked it and now with telus. My data dropped constantly and now I'm using the newest litening rom and now it only drops maybe once or twice a day so a huge improvement

If it's any consolation, I ran my Virgin SIM over the weekend (just to burn up the data I had to buy for a 1 month) and the same thing happened on stock firmware.
In my case, it would put me in "emergency calls only" mode, saying I wasn't authorized for the network (i.e. it wasn't recognizing my SIM). Tried the usual stuff (re-seating SIM, using the Telus SIM, reboots, cache wipes, network WCDMA/GSM selection etc), and nothing fixed it, it just seemed to come back on its own when it was good and damned ready no matter which SIM I used.
Flashed to "Frankenstein" KG3 on Sunday, and neither the Virgin or Telus SIM has lost network since then, in the same areas. WiFi seems to be working better too.

Upgraded 4G Xoom LTE Connectivity Issues

Greetings All,
Got my Xoom back from its 4G upgrade last week and I have been noticing some issues with connecting over the 3G/4G network now. I use pocketcloud to connect to computers over RDP and when connected over WiFi networks, it works fine (computers connected to networks other than one I am connected to WiFi on), but when using the 3G or 4G connection on the Xoom, there is a network connection error. I tried it out on my incredible and it works just fine. Also, sometimes I get an error "cannot update" from the engadget app.
Also, the new market would not install some of my apps, like ThinkFree Office for example, I worked around it by using the web interface of Android Market on my computer and it worked fine.
I sent in the Xoom completely reverted back to stock 3.1, I recieved it with 3.2.2 stock. I cleared memory after I got it back and did a factory data reset. Not rooted, and no other modifications have been made.
I'm at a loss as to why some connections are causing the network to flake out.
Regards.
I read on here that some of the app installation issues were due to the possible change in pixel density that took place with the upgrade but that is something you can change back if you root.
I'm noticing the same exact issue and have no idea what is causing it - let's see if together we can figure it out. It's extremely flaky so far.
I got my upgraded Xoom back today and noticed the exact same issue. It wouldn't activate on the setup screen and prompted me to reboot. After reboot, it connected to 4g just fine and showed the 4g icon below.
I then went into the market to install my apps. It installed Thumbkeyboard just fine but when I went to install others, it stopped at 8.03k on the download. Did this for every app i tried.
I turned on wifi, connected to my AP and the downloads worked just fine. Even tried a couple reboots before doing this and it didnt work.
My 4g signal is about 75% so it's strong.
Very strange...
Power off
Remove SIM.
Put SIM back in
Power on
Done. Worked for me.
I take it back, still having all kind of issues.
just got mine back this morning, and it wont connect to anything! no 3g, no 4g, no wifi... nothing. WTF!?!?! restarted, pulled sim, etc...
going to do restore next and see what that does.
Same connection problems
Got my LTE upgrade back.
When I am at work I cannot update Touchdown from inside the firewall (not sure why) so I flip back to Verizon to refresh by shutting down the wifi. When I do, I noticed that the xoom would drop the connection (three bars) and then not reconnect. When I try to turn on the wifi it stays grayed out and neither system will connect until I reboot.
Went around with VZW tech support, they reported that the unit was registering on their network but not connecting. Sent back to Moto for further testing, got the unit back (they reported it was a software fix, no other data) but the unit continues to have the problem.
Stock 3.2.2 xoom with LTE
Any suggestions appreciated....
Has anyone been able to resolve this issue?
Hello, I am still having all kinds of connection issues after I received my device from Motorola. After a reboot the xoom will connect to the Verizon network but If it stays idle for some time, I lose the connection and it will not connect until I reboot the device.
sent it for replacement
I had the same problem. I had to send it back once for 'repair' (no improvement) before Motorola replaced the unit due to an undefined hardware problem. Keep calling or go to a store.
I had something similar when I got my Xoom back. Apparently the geniuses at Verizon never added the SIM to my account. Took multiple calls/emails to get it corrected. Once someone realized it was missing it was corrected in about 10 minutes.

In your case did you have sporadic connection or, without the SIM number, were you completely unable to connect?
BTW, I missed this thread when it was fresh (as I was traveling) but I've had the exact same issues since the LTE upgrade. When it happens, the only way to reconnect is to reboot.
I used to be able to get it to reconnect by switching airplane mode on and off. Sometimes I had to reboot. Friday, even that did not help. I was furious. The next day, the update pushed out to me via wifi. I guess the servers recognized me as a customer again even though I already had a 2 year contract. Some people got the dataplan because they don't use wifi. I love the shortsightedness of the people who come up with this... not.
At least I haven't gotten disconnected since the patch was installed.

[Q] Data connection problem .

I have bought my Lg G2 last saturday. I'm still researching the phone and so far it's great except one thing. Problem is when the phone is removed from charging it refuses to establish a data connection. This happened to me twice and every time in the morning after the charging.
Solution is restarting the phone. If not, it just won't connect . When i go to the settings it is turn on, but there are no arrows at the top of the screen and it doesn't work. Otherwise , after the restart it works normally all day. I keep turning it on and of and it works fine.
I think it is a software problem, since I have a network signal, but I'm not sure.
Is anyone having a similar problem?
Thanks

I'm using original usb cable and charger, but with extender , because of the electricity. Phone is from England, and I'm from Serbia .
After the last night charging I had the same problem, but this time I used toggle between Airplane and Data . After that everything worked fine.

Hi, i noticed this too since a couple of days... Trying To figure out what the issue is ( in possession for 2 Weeks)
I can re-establish data connection without reboot by clicking in select automatically in network operators in data /mobile networks settings. So it will reregister on the network.
Guess we need to notify lg about this issue/bug for a fix.
my sprint g2, will drop data connection occasionally when switching from wifi to 3g or from lte to 3g. so i would say there is some kind of real issue here
Same problem after rooting
I'm having the same issue, the data connection drops, mostly after going into stand-by. The problem started to occur a few days later after rooting the LG G2. I have tried the temporary solutions above with succes, but there is no final solution to it. I wonder if the device intentionally starts to brick itself after rooting, I heard the LG G2 has a lot of root checkers (says the noob).
Anyone contacted LG yet? Or tried flashing their device?
I'm having a similar issue with my G2.
After switching off wifi, data won't start.
I have to click search network then it would go on.
Would it be something to do with the modem?
When i had my Samsung gs2, I had problems with random dropouts, then I found a way to flash new modem software and all worked fine with better reception and no dropouts.
I sometimes loose network connection completely (no service) when switching from 3g to 2g or vice versa, no issue with 4g what I've seen.
Though I have this BBS, looks very alarming I must say, does anyone have similar to this:https://db.tt/aKsiw0Xe
https://db.tt/9iMHIZvm
issue fixed
hi after a recent software update (mine was D80210c-HKG-XX, build number JDQ39B,...) the data connection issue is solved for me (also made a LG support case).
But my NFC funtcion stopped working now...
Same here. Ive got this issue after rooting the G2. It cannot connect to mobile data after Im away from wifi connection. Switch airplain mode on and off helps but its annoying even if u have more email account. Another problem after rooting was freezing and restarting phone after mouse connection. But next day was everything fine and its untill today. Have anyone similar issues with custom roms?

I am rooted running Digital Dream on a Verizon VS980 with 12B radio installed. I loose data or go down to 1x all the time. I have to toggle airplane mode or reboot to re-establish 4G connection. Is there something else I can do. I love the phone but the data thing is annoying. Is the antenna really that bad in these phones?

I think and Im almost 100% sure that this must be only software problem, because when the data is runnig, it runs fast and stable. No additional inconvenience.I hope next upgrade (update) will fixt it. However Im really surprising that u have same problem on custom ROM. Im using only airplain mode to switch the data on. I needent to restart device, but it is really really annoying.
Hi everyone, as I wrote before got data connection issue while getting away from wifi. The data cannot start automatic. I found out that it happens only if GSM/ WCDMA /LTE automatic connection is selected in the settings. When I adjust GSM/ WCDMA automatic connection - everything is ok. I was trying automatic switching and runs perfect. So if u dont use LTE, better say if the WCMDA is enought for u, it can be less annoying solution as manualy turn on/ off airplain mode. I hope next update fix this issue at all. Have nice day.

It seems better (still not perfect) I wiped everything including formatting the system partition and re-installed... But thanks for the replay!
Also, I don't have to reboot ... toggleing airplane mode takes care of it, i was just saying reboot is another alternative.

This is definitely a software problem, but I have no idea how to fix it... when I first rooted everything was fine (I was on Malladus). Then I went to CM-based ROM and it was still working well.... then I updated my PRL (*228) and things started going south and I haven't been able to get it back working since.
I'm thinking of going back to Stock and starting over from scratch to see if I can fix the problem.... if anyone has an update on this issue I would greatly appreciate some advice!
potential fix for this issue?
Hi everyone. I had this phone for about 3 months. and the data connection thing has been annoying for me.. So the problem to start off with is at first I dont seem to get LTE at all during the first 2 days. I found online that the 3845#*802# or *#*#4636#*#* got me into adding LTE back into the system but problem is when I reboot. it goes back to WCDMA only or GSM WCDMA. and I lose LTE. But atleast I have LTE when I didnt reboot it. Then I found another problem which is losing data after I used LTE for a while. It won't reconnect until I reboot the phone or SOMETIMES it will return if I go into airplane mode and back. After some long research. I found this to be working for me.
So this is my story of how I got it to work for me
To start off with. This is what I am using
LG G2 D802
Android version 4.4.2
Baseband Version M8974A-AAAANAZM-1.0.190082
Kernel Version 3.4.0
Build KOT49I.D80220b
Software D80220b
My provider is Metropcs so if anyone has other issues with other providers. I don't know if this will help you.
First thing this phone needs is it has to be rooted - that part you do your own research and wont be hard since you are on XDA!!!
Then to get LTE working, you will need to type in 3845#*802# on your phone to get into the hidden menu
LTE-only ---> Modem Settings ---> RAT selection and select GSM / WCDMA / LTE Auto (will display SUCCESS) tap OK
This will give you LTE from the phone but it will not give you this option in your Mobile Networks / Network mode section (Preferred network mode) Atleast it didn't display it for me.
For my phone I had to edit the build.prop file for it to show it in the preferred network mode list.
In the build.prop file. You will have to look for this line and change the 9 to a 11. I've also saw some post about it being not a 9 and have to change to 12 for some networks. ALSO MAKE SURE YOU DO NOT CHANGE IT TO A NUMBER 0. It will crash the phone.
From
ro.telephony.default_network=9
To
ro.telephony.default_network=11
After this I got me LTE connection but issue with the lost of settings after reboot started. So next part helps with the reconnection after reboot. I got this from a post in XDA So give credit to the person that posted this. Sorry if I dont have it handy as I wrote this
- Root
- Install and activate Xposed fw
- Install and activate Intelli3G module
- In build.prop change ro.telephony.default_network=9 from 9 to 11
- Create a Tasker profile of type Event -> System -> Device Boot
- Associate the profile to a new Task of type Misc -> Send Intent
- Configure the task by setting in the "Action" field the value "action.intelli3g.CHANGE_NETWORK_TYPE" and in the first "Extra" field set the value "extra.intelli3g.NETWORK_TYPE:10"
Doing this got my reconnection after reboot fixed. and LAST is the problem of randomly losing data connect until I reboot the phone. and after a long test.. This is my result. The phone lost connection due to trying to connect to LTE with non existing band. I don't know too much about those but from my testing. This is how I made my phone worked and it has been working for the last 2 weeks without any issue.
Go back into the hidden menu with 3845#*802#
LTE-only --> Modem Settings --> LTE Band Selection
Here you will see a Band with a number.
MetroPCS supports band 2, 4, 5 and 12
Since this phone doesnt have 12. You only select 2, 4 and 5 then just push back until the hidden menu closes.
Other providers. I dont know what band that they use. but i am guessing if you only select the bands that company supports. You might not have that issue with losing data anymore.
Please press thanks if this works for you.

No data after having WiFi enabled for a while

Hello,
I've had this issue across more than 1 device and more than 1 carrier.
Here's what happens:
I enable WiFi, and for a while everything works as expected. I can send and receive MMS messages. I can disable WiFi and go back to my 4G connection.
The problem is, after an unknown amount of time, the phone drops the 4G connection in the background. I only know when I can't receive/send MMS messages anymore. At that point, if I disable WiFI there's no 4G data connection, and I have to turn Airplane mode off and turn it back on.
This is really annoying. It happened to me using Sprint and a Galaxy S4 (both stock and custom ROMs) and it's happening to me with a Galaxy S5 from MetroPCS. (I've used the stock Metro ROMs, Stock T-mobile ROMs, and Custom T-mobile ROMs).
Right now I'm using a Stock T-mobile ROM with the latest firmware, carrier is MetroPCS.
What can I do so this doesn't happen? It's really frustrating.
Thank you for your time.
Disabled "Smart Network Switch" in WiFi Settings?

Disabled "Smart Network Switch" in WiFi Settings?
Click to expand...
Click to collapse
Hello.
That's already disabled.
Should I enable it?
I tried with "smart network switch" enabled and disabled and problem still happened.
My S5 G900F Android 5.00 (Smart Network Switch disabled, Power Save disabled) on EE UK has had this problem for 9 months after phone upgraded itself to Lollipop (EE win the accolade to being the SLOWEST ON THE PLANET to provide Android updates.....). Since Jan 3, my wife's G901, a couple of weeks after it upgraded from 5.0 to 5.02, has developed the same problem. Neither phone has ever been rooted or other.
I have fruitlessly searched everywhere for a solution without success. EE Customer Services Tier 2 & Samsung's own service centre have failed to fix it. EE & Samsung blame each other for 5.1 or 5.1.1 not being available for download. Neither is prepared to resolve the issue despite hours on the phone. Have tried Safe Mode, Factory Reset, clearing everything, reloading APNs & Samsung even reloaded Android. All a waste of time: Many many days of it!
After approx half an hour connected to Wi-Fi, only way to get the mobile data to connect, is either reboot, enter & exit Air-plane mode or flip the 4G > 3G > 4G connection under More Networks. Have tested the fault in different cell areas countries and continents; fault is same everywhere.
It seems there are quite a few sufferers of this problem.
Samsung S5 keeps losing data connection
I have the same problem. My new Samsung phone loses the data connection (even though data is turned on) and I can only re-connect by restarting the phone. The first EE shop I took it to couldn't help at all. The second gave me a new SIM - that didn't work. Then I tried online support and after 3.5 hours of my life, in which I was passed on from one person to another, they completed a factory re-set - which didn't work (and additionally lost all the personalisation of my screen and some of my contacts). So I now have a not-very-smart phone which I have to re-start every time I want to use data. This is a business contract and the phone is less than two months old, but I'm not getting any effective support from EE. Android version is 5.0.2
me too, since last update. and app 'phono' shows "mobile data off" not got a time on it, but when i leave wifi coverage, it wont reconnect to cell data 2g/3g/4g. flightmode toggle to restore.
Abandon hope if you have this intermittent mobile data problem!
...at least until there is a software update, though I have no idea if that will help.
I have now tried a new sim card, a factory reset, and a replacement phone - which was provided only because I'm a business customer and I found a sympathetic member of staff. *By the way, I was told that if you are personal customer they won't consider replacing your phone if it is more than a month old - even if you started complaining about the phone as soon as you got it, the chances are a month will have elapsed by the time they put you through the hoops of a new sim, reset etc - and then it is too late to insist on a replacement phone.
In any case the replacement phone didn't resolve the issue so I have reached* a dead end. My phone fails to connect to data after having been connected to wifi - you have to do it manually each time you move away from a wifi connnection. At first I was doing it by restarting the phone, but am now following the advice of someone else who has the same problem and am going into flight mode and out again. *
This is not satisfactory, and it seems from reading forums that EE are to blame for the problem rather than Samsung, but I'm not 100% sure about that.*
Possible solution that works, for me, at the moment!
Having suffered this issue of my S5 (SM-G901F) not connecting to mobile data after being on Wi-Fi for a while unless switching airplane mode on/off for a few weeks; although it has probably been happening since the update I received late December; I have tried all of the turn this switch off, factory resets (x2), etc, etc, etc. and Googled the issue without success.
I have found this thread interesting, and I even tried calling EE support only to be told "you have tried everything that we would tell you to do" and "it wouldn't be a sim card, or handset issue, sounds like software". The reply was basically that like-it or lump it until the 5.1 update is released "by Samsung not EE because EE do not release Android updates". [Perhaps EE don't release the updates, but the stock rom is tested by them and their bloatware added before they eventually release it!!!]
Following my last reset I tried selectively re-installing the apps I used incase that was causing the issue. No Luck!
One last thing I tried was to look at every system 'thing' that I could find which used/switched any part of the mobile/mobile data/wifi - in addition to the settings I had already tried (all of which were mentioned in this thread previously). One thing I could not find not mentioned here, or anywhere, was the VoWi-Fi call on/off which I had always set to on as I do not live in a great reception area. Calling over Wi-Fi is great when you don't have a strong mobile signal.
Having 'played' with this setting for the last 24 hours I have found that the VoWi-Fi on/off appears to be a possible cure - for me anyway.:fingers-crossed:
When VoWi-Fi was set to off and leaving the phone connected to Wi-Fi overnight, the S5 immediately switched to mobile data this morning when I turned the Wi-Fi off . It continued to switch between Wi-Fi and mobile data all morning whilst out and about in and out of Wi-Fi connections - Woop Woop!!!
I then tried switching VoWi-Fi on (with Wi-Fi on and at home), leaving the phone for a number of hours, only to find that when I turned Wi-Fi off the phone refused to connect to mobile data even with a 'decent' mobile signal. The only way to get it to connect was to go back to switching Airplane mode on/off.
Switched VoWi-Fi off again, left Wi-Fi connected, left the phone for a couple of hours, etc. and hey-presto immediately switched to mobile data when I turned the Wi-Fi off. [Dances around the room because he's got the S5 automatically switching to mobile data again. Even though I'm at home with a great fibre internet and strong Wi-Fi connection!!!]
I do not know if this could be a solution for the others who are suffering from this issue, but it appears to be a solution for me at the moment. I thought I would share as your previous posts have helped me and you all seem to be pulling your hair out; like I have been; trying to find a solution.
Try it, it may work, but don't shoot me if it doesn't!
It's encouraging to know that I'm not crazy. I've had this issue across two devices and carries.
John,
Thank for your suggestion about WiFi calling. Unfortunately, I always have it off! I never used it, so maybe I should try turning it on? We'll see lol.
At this point, I think this is going to be my last Galaxy line phone.
Is it wi-fi calling that's causing the problem?
I have wondered if there is a link with wi-fi calling, but haven't tested it properly. I signed up with ee and bought the Galaxy phone specifically so that I could use wifi calling, as the town where I live (in the Scottish Borders) doesn't get a mobile signal strong to work reliably indoors from any of the networks. I'll try turning off wi-fi calling to see if that sorts the data thing (though I see that for one person above it did not). That would mean I wouldn't get calls or texts when I'm at home so it would not be a permanent solution for me. But in fact the wi-fi calling is not reliable anyway....

Brian,
You never know the way things are going with this issue; given that nobody seems to be able to pinpoint the fault; turning it on may just sort it!!!
still no change and its a pita.....
