Hello all, I am having a problem with my phone. I currently have an htc hero and am on Alltel's network. I have been a root user for some time now, am running a cm7 nightly and I recently decided to back up my rom and do a system wipe to clear up my phone and hopefully improve performance a little. After backing up my rom and performing a data and cache wipe, I re-flashing the nightly on my phone and I now no longer have data signal. I can not access the internet, the android market, email, Facebook, etc. I can however still make and receive phone calls and send and receive text messages. I tried flashing on several different versions of cm7 nightlies and RC's and every time I encountered the same problem of no data signal. The only time I receive data is when I restore my phone to an earlier recovery from before I flashed a new rom on my phone right after rooting while still running sense. I have also tried un-rooting my phone in hopes of re-rooting and re-flashing a rom to fix the problem with no luck. If anyone has any ideas or can help in anyway I would be extremely grateful.
You guys can not tell that out of all of you "genius'" out there that not one of you can help me with my problem?!?!
So apparently I only lose data signal in certain towns. When I am down at school I have no data signal but only when I run cm7. When I am at home I get full data signal. Anyone have any ideas?

Hi-
I have the T-Mobile LG G2x. I have been using and updating my ROM weekly with the latest port of MIUI ( WhiteHawkx's version ) -- currently on 1.12.01 [12.02.2011]. I have a horible time keeping my APN up. I can make calls of course, and I can use data, for a while, but then after 10 - 20 minutes I lose my APN and no more data. I have tried the "Power Button and Vol. Down" trick, but even tho that will fix the data connection, it is only for a short while and I will lose it again. There is NO rhym or reason as to why this is happening.
Am I the only one that is having this serious issue ?? And it is not my data being throttled. When it happens it is gone completely until I somehow force it to restart.
Any thoughts on how to resolve this ?? Are other people having this issue also ?? It happens to me about 30 times a day.
One bit of information: If someone pushes me a packet of data (like a whatApp message or KiK message) my APN will start working again for a little while. But only if they pushed it to me. otherwise data is still not going out. And I do NOT have anything set to sleep.
Thanks for any insight !!
John

(not specific, but I posted a similar issue in this thread)
These are just from the first couple of pages from the General and Q & A forums of topics with people having issues with one or the other:
APNs lost
Data dropping
Losing network connections
etc
Certain roms seem to be slightly better, but people have had issues (like me) with everything from stock, to CM7, to MIUI. This is more than just a coincidence. I think LG must have shipped a batch of POS G2xs. And if you have NEVER had an issue, then count yourself as lucky.
Thank you for the reply..... but my issue seems a bit different. I do not have any trouble with my signal or cell talk dropping. My phone never drops a call. This is only data related. Like going to the Android market or using any app like messenger, whatapps, kik, Skype, ect.... anything that uses data will eventually stop sending, until I reboot. my SIM card is fine.
Any other ideas ?
Ah, sorry I misunderstood. You might want to check out a different kernel then.
im having this issue as well
except i only lose my apns if i shut off than turn back on my phone, im using rg2x
S-Off (juopunutbear)
Clockwork Recovery 5.0.2.7
After flashing the cm-9-1-(3-0-49)-r8.zip on the http://forum.xda-developers.com/showthread.php?t=1912582 post and the kernel-3-0-49-r8, I had everything working except for MMS. I made the mistake of playing with the APN settings in an attempt to get the messaging app that came with the rom to send MMS messages. I realize now that I should have just used a third party app, which I was later able to do, but somewhere along the line I lost my cellular data capability. I used the APN settings from T-Mobile and tried some other settings, as well. The weirdest thing is that there were times when I would have cellular data for a little while, but the longest it lasted was a few hours and it never seemed to be anything except 2g (E). I've flashed the radio via hboot, flashed the stock rom (which got the cellular data working constantly), and reflashed the cm-9-1-(3-0-49)-r8.zip, after wiping data, cache, and dalvik.
Thank you in advance for any help.
MMS
I was able to get the cellular data working again by unmounting and formatting the data and system, but I'm still unable to receive MMS messages, even with a third party app. However, I can send them.
MMS over WiFi
It looks like the problem is only over WiFi and that it's a known issue, at least with Cyanogen. Sorry for being a bit of a noob. I hope this helps someone else.

Hello,
is the problem with WiFi in general or just WiFi + MMS?
Actually I have WiFi issues (WiFi is on and with full signal in status bar, but after a time, I have to turn it off and on again to make the WiFi work).
Thanks
I hope you guys can help me out with a problem. Sorry about the long post ahead, I'm just trying to give as most information as possible.
Introduction: I recently installed the latest releases to see how jellybean was coming along on the Desire S. I flashed PACman and then CM10. I liked them a lot, but I usually prefer to wait until a final release, so I reverted my backup of CM7.2. One week later I notice my internet connection is very unstable, I don't know if it's my carrier's fault, or the upgrade messed with something and the backup didn't restore, and reflashing CM10 changes nothing. I didn't notice any problems right away after testing the other roms, but like I said, everything happened around the same time frame.
Problem: First of all, if I enable 3G, it will almost never connect. Sometimes I get a 2G connection, but most of the times there is no internet at all. On 2G only, it seems that a few minutes after screen-off, the connection drops. Only after I wake the device, it realizes the connection was down and resyncs with my google account. And even while awake, 2G is still very unstable, I get numerous network errors on the facebook app timeouts on google play.
Device info: Should I test other radios? I noted that it came from the factory with 3822.10.08.04_M, and was on 20.28b.30.0805U_38.03.02.11_M (I don't remember when that changed, I don't think I've ever explicitly changed a radio). Now I just flashed 3822.10.08.04 back, but it didn't change anything. Could HBOOT also have any influence the problem? I remember I downgraded do 0.98 so I could S-OFF using Revolutionary. Now I'm on 6.98.1002.
Lastly, probably a logcat would help. How should I go about doing it? Reboot phone, wait for it to connect, put it to sleep until it disconnects, wake it up, wait for reconnection, then logcat? Since the problem persists both on CM7.2 and CM10, I decided to stick with 10.0 (nk111's cm-10-20130109)
Thanks a lot in advance!
Here's a logcat I took today, if anyone is willing to investigate. Started recording after gtalk was online, turned off the screen, waited a bit, turned it back on and checked that gtalk was offline.

I'm having similar issues on Pacman 18 and 19.3.
My connections seem stable, but I cannot switch between 2G and 3G without rebooting. If I don't reboot, the phone has no internet connection.
Also, on 3G, battery life is very bad.
I'm wondering if it would help to flash a different radio. I never changed the existing radio.
Hey guys, quick background. I bricked my SGS3 and had to have it replaced. I think I got a refurb phone because from day one I keep having the same issue. First day I got the replacement phone I rooted it and flashed CleanROM 5.0. Everything was peachy until I noticed that I have no 4G or 3G service. In fact, I had no data connectivity at all. My phone can make calls, receive texts no problem, won't connect to internet. If I restart the phone, I have 4G right away. After a few minutes, the 4G icon is on, but the phone won't has no data connection (when I say data connection I mean it will not go online, no internet, no android market, still have voice and txts). If I attempt to go on internet, I get a message saying "No Signal Found For Mobile Networks". I have installed Network Signal Info and right after a restart it says 4G LTE, data connected, upload+download activity. After a few minutes, it says 4G LTE, data connected, after a little while, it will switch to EHRPD, with data "connecting". Also, in the System tab, it will tell me my IEMI and version of JB running, next to "Radio", it says "unknow". WiFi works perfectly btw. My IEMI is perfectly fine,
I had it backed up. My phone number is still there.
Here is what I had tried so far: Switching into and out of Airplane mode, different programs that reset mobile connection, flashed different custom ROMs, flashed the stock kernel, flashed 3 or 4 verizon Modems, Data wipe, cache, Dalvik wipe, Odin'ed back to stock 4.0.1 ICS and had upgraded it to 4.1.1 via verizon software update, changed the SIM card, and reprovisioned the phone with that *3767*whatever the hell code. I'm out ideas.
If anyone has any other idea that I can try before I take it back to Verizon, please, let me know.

Did you go into your mobile data settings to make sure you're on CDMA/LTE? If not I would select and reboot the phone and see if the problem persists. I don't know if you have tried this but it's worth a shot.
I'm having literally the same exact problem with my mom's S3 except for it's not rooted, complete with 'download + upload activity' and 'unknown' radio. I've yet to find anything in my search, but if I do I'll post it here.

I did try that. Nothing seems to be working.
Hello, I'm hoping someone here can help me. After several hours on Google I can't seem to find a solution to my problem.
My Nexus 5 will connect to LTE with no problem most of the time, but every couple days it will connect to 3G for a while, and never switch back. I have preferred LTE setting enabled, and have tried to force LTE only in the *#*#INFO#*#* menu, but when I do, I lose all data, and it won't connect back again ever. The only way to fix is to factory reset my phone. I have tried changing the preferred to 3G and back, changing INFO to LTE/CDMA auto PRL again, and rebooting my phone several times. I reflashed to Radio, and restored system data using titanium Backup to a time where it was working. I am totally out of ideas. I would really appreciate any help. Running Mahdi Rom 2.9 Rooted.
