[Q] Data Connection Issues - Samsung Galaxy Nexus

Before I start let me explain I've searched for the answer to this and have yet to find any concrete answers. I've had my Verizon G'Nex since release and had it rooted before Best Buy had even run my credit card. I've been running SlimKat 4.4.2 Build 5 official and CWM Touch. Ever since I updated the ROM (clean flash) to the 4.4.4 experimental I've had problems with both 3G and LTE connecting to data. I have signal, in some cases "4 bars" worth, but it never actually connects to data unless I reboot the phone - that will last for a couple hours to a couple days then it's back to no data. I completely wiped the phone - data, cache, system, and sdcard...everything that CWM could possibly let you wipe - and then sideloaded the previously stated Slimkat which worked for months prior without issue. The problem still persists, and has gotten worse. I cannot use LTE at all. It will not connect regardless of what I do.
So my question here is what parts of Android affect data connection? Is this entirely ROM dependent, or does kernel have something to do with it? I'd rather not go through the trouble of finding another ROM that has speed and features of SlimKat, or randomly flashing kernels just to find it doing the same thing.

Well in not sure about this option being in your version of cwm.
However if it has wipe efs data as an option and you wiped it nothing that you do to try and fix your connections will work.
I found this out the hard way and had to buy a new gnex. Tried everything but couldn't get my efs data back.

No option about EFS. That's the thing that bothers me. I have voice and text, it can 'see' towers, it appears to be able to 'connect' to towers, but it's like it's not pulling an IP address or it can't contact DNS.

[Q] Data network not connecting

Hi. Well I had rooted my phone and was running CM6.1.1 with snapdragon kernel. When the evo shift came out, I bought it and changed over to the shift. 3days in to using shift, the micro usb port failed and would not charge. It wouldn't even recognize when connected to my computer. So had to go and return it.
But when I changed over to evo, it started having problems with data connection. I could make calls but it would not be able to connect via 3g. It could connect through wifi but that was it.
So I unrooted my phone using .ruu and haven't tried it yet. Could you guys help me out and advise me in what option I have. Thanks again.
I had a similar problem when I had my hero....I lost 3g and ended up finding the solution was to wipe all, flash a sense rom and then go back to cyanogen....
Thanks. I'll try that and see what happens. I'll switch to evo tomorrow and see how it goes..
i had a similar problem with 3g data being very faulty after i updated all of my radios to the latest versions. what i did to fix the problem was full data/cache/dalvik wipe and then flash the radio: EVO_Radio_2.15.00.11.19, flash the wimax:EVO_WiMAX_27167_R01, and flash the PRI: EVO_PRI_1.77_003. Prior to that, i had the latest PRI and it would constantly screw with my data connection, so whatever you do, do not update to the latest PRI. Its actually been said that something weird is up with it and that this problem is common.
the radios can be found right here:
http://forum.xda-developers.com/showthread.php?t=715485
good luck man, hope this helped!
I have the same issue. I went from CM7 to a sense ROM and I still dont have date even after the new radio updates. Is there anything else I can do?
Have you already tried reverting back to your old radio that worked?
sure did. Nothing.
I actually did a full unroot using ruu. Then started my phone again back in stock mode. It worked after full unroot. Now I re-rooted my phone and back to using CM6.1.1 with snap dragon kernel.
Same Issue Please Help
Im having the same issue as the OP. I went from CM7 to a sense ROM and lost my Data connection. I can only connect through wifi. However I can't update my profile or my PRL This is a pretty big issue for me as I can't use any data features on the phone except when connected via wifi.
Can someone please suggest a way to re-establish my ability to connect to the sprint network. I do not have 4G in my area so I can't try that route. I have searched the forum for the last day and a half and still haven't found a solution. Ive tried reflashing the newest radios and still no luck. I have cleared the dalvik, cache and factory data reset mutiple times and I have tried sprint lovers newest ROm and also even tried reverting back to the original backup I took when I first rooted before I flashed any ROM's and still no luck. I also tried the ##3283#/MSL code/Data/ restore option and still nothing.
ANY Suggestions? Unrooting would be a last resort option followed by going to sprint and getting a new phone.

going to a sense rom, dialing ##data# and then entering your msl, then going to edit mode, top section, hit menu, and do a reset?
this usually fixes alot of data issues from what i am aware. It won't harm your phone anyway.
Yeah I have tried the ##data# restore multiple times and still nothing. It will reboot and begin the hands free activation but it never successfully completes it. Afterwards when I try to update profile it just sits in a loop saying "the network is preparing you services..." for 20 mins and then times out with nothing happening. I even tried the ##data# restore method again after reading this, for good measure, and still nothing.
Is it possible to connect via 4G and update my profile even tho I cant via 3G? I'm about an hour away from any 4G service I think Cincinnati may be the closest.
this is extremely frustrating and the worst part is that I dont know how it happened as I followed every instruction to the tee and Ive flashed mutiple multiple ROMS over the last 6 months and have had no problem until I tried going from CM7 to myn's warm2.2 rls5. After flashing the ROM and wiping EVERYTHING except the SD card I flashed the new Radio's (Cualkin's Combo pack with the newest Radios) and that's when I noticed the data connection was gone. I'm not sure as which step of the process caused the issue as I didn't notice it until I began to go thru the initial setup on the phone and was unable to connect to my gmail account.
I have backed up a few versions of rom's. Would they have the Data info I need and maybe a could just copy and paste a file or does this info need to be downloaded from sprint in order to setup the phone?
Please any advice??? I'd like to try all my options before I reroot and exchange it, If unrooting and returning is my only option can someone please point me to a good guide for the process? I used Unrevoked 3.21 for the root.

[Q] Data and Phone network connectivity problem

My Verizon GN is having difficulty connecting to my phone and data networks. It all started on the day of the outage this week. I assumed it would all fix itself, but it has not. I've snooped around the board quite a bit and it seems all other users have had their connections restored.
I first noticed the problem on Thursday morning. My data status in notification bar would drop to display no "bars." It does not switch over to 3G. I figured this problem would resolve itself once Verizon fixed its network.
Then I tried to send a text and it couldn't be sent. I tried to call someone and it would not dial out.
But these loss of connections are not persistent. Eventually, the 4G works for a bit then disconnects again.
The phone network seems to be doing this as well. Sometimes I can call/text, other times I can't.
I was considering wiping my phone and flashing a new ROM or getting the stock ROM from google to flash. However, I seem to be having trouble with clockwork mod. When I try to reboot into recovery mode it takes me to what I assume is download mode (shows an android knocked over on his side with, I think, a red X).
Is there something simple I can do to fix my data/phone network connection?
If I have to flash back to complete stock, then how do I do this without being able to access recovery?
If all else fails, will I be able to do a factory reset considering the current scenario? I assume I would need to do this before bringing it to Verizon for service.
I appreciate any help provided. Here are some other details that might help.
Rooted with stock ROM
4.0.2
Baseband I515.09 V.EK05 / I515.EK02
Kernel 3.0.8-gaaa2611
Build ICL53F
/edit/
I should have mentioned I had the most up-to-date version of CWM. I just reflashed it with ROM Mgr and it booted into recovery, so that's good.
Well ****. I went into CWM - Advanced - Fix Permissions. I thought hitting Fix Permissions would bring up another menu. Instead it fixed permissions. Hopefully I didn't do something stupid that I don't understand.
I flashed the GummyNex Rom hoping it was a kernel issue or an issue resolved by going from 4.0.2 to 4.0.3. It's been a little better it seems, but it did drop both networks once already and it's only been 15 minutes or so.
The new ROM definitely did not solve anything. I don't know what to do. I need to find a way to get back unrooted, unlocked, stock. Unfortunately, I'm running Mac OS X 10.4.11 which current SDK doesn't seem to support.

I recently had CyanogenMod 11 installed on my phone and I noticed phone calls, messages, and WiFi worked but when I turned my Mobile Data on, It did not work even though it showed it was on.

It's PlatinumTel (PTEL), which is a t-mobile mvno. I should note that i have the bootloader and the modem matched, have tried factory resets, and even downgraded to previous version (before updating bootloader to latest so i don't brick). Ptel tells me i need to update my APN, which basically was their standard msg... no help there. Thanks.

Hi, so... there are bunch of links and downloads on that page... i do have the latest bootloader and modem... can you tell me what you think i should [try to] update to make the mobile data work? BTW, at least on my phone, the mobile data icon doesn't even show. Not even 3G or whatever... thanks for your help.
RESOLVED!
Ugh. So after countless flashes, resets and wipes, turns out that PTEL needed to do a Data RESET on their end. So much misery for such a simple solution that they could have given me. If you're a PlatinumTel user, and this may apply to many other providers, please try telling them to reset their data service for you before trying anything else. Hopefully you won't go through the misery and time wasted that i have gone through.:cyclops:

All of them are stock but I personally chose upndwn4par - Full - Features : Odexed, Rooted, Knox Removed because I really didn't know what the other ones did. (PLEASE NOTE : Neither the developer or I are responsible if you brick, or mess up your phone! This also deletes everything on your phone so do backup if you want to save your important files.) When it finished downloading, I put the file on my phone's internal storage (SD card works too) then went into recovery mode using TWRP and installed the rom onto my phone, then while I was still on TWRP, I deleted the cache and data, it then reboot and then I had to set up my phone as if I had just bought it.

THIS NEEDS TO BE PROCLAIMED!
PTEL locked us out of voice once before, which also required a reset. That was also with a phone change so maybe a security measure? Never thought about it happening with data.
So many hours wasted.
On calling, the PTEL CSR first reset the data, then helped with a new APN. Note that even with the correct settings in an existing APN and the data connection freshly reset, the phone (SGN3) refused to connect, even after a reset. Added APNs had to be deleted, then a new one created, which then connected immediately. (Pissed and happy at once.)
Thanks, @geesedude, for this info; wished I'd found it sooner. (Have to stop assuming that if it doesn't work, must be something I'VE done.)
Glad that the information helped you. Yeah, i mean... since we mess around with our phones, we always first assume it's something we did, which really can't be blamed for thinking that way. Like you, i searched the web for a solution and it was out of desperation that i called ptel, and the CSR happened to suggest it (they were out of ideas, too), and it happened to be the solution. Not sure why they have to do this in the first place, but i am guessing that there are stricter guidelines from TMobile for the MVNOs, and they have to do some things manually. At least now i know to contact them first before spending hours searching for something that may not exist!

[Q] No data when connected to 3g

Hey guys,
I have a really weird problem that's been persistent throughout my ownership of this phone. If my phone ever goes into 3g mode, I can't access the internet on my phone or do anything that requires data. I live in a mostly 4g area so it isn't normally an issue, but when I travel elsewhere it becomes a huge headache, forcing me to go running in search of a wifi hotspot.
I have the newest radios, and even flashed the latest RUU to reset my phone to stock. The problem is still there.
Is this an issue for anyone else, or does anyone have any suggestions as to how I can fix it? Any help at all would be GREATLY appreciated. Thank you in advance.

I have the same issues regardless of what ROM I'm on. 3G is pretty iffy for me, sometimes I will get a data connection whereas some other times I don't get any data at all. I would hope that phone should say "no service" or something like that. Your best bet at this point is to try to do a factory reset to rule out any residuals from other ROMs (remember to make a backup before hand on a computer because it will wipe everything). Also take the time to update firmware

Keep in mind sometimes the recovery can cause issues, I remember I was using specific versions of TWRP and most of the time it would work fine but other ROMs I had errors. I can't comment on Philz cause I never used it. Currently on TWRP 2.7.1.1 and so far no issues.
Lastly, the only thing I could think of is try getting a new SIM card. You want to go to the corporate stores and NOT the authorized Verizon retailers. You'll know because the authorized retailers will charge you for a new sim card whereas corporate stores do not.

Wow, thank you for taking the time to write all of that. It means a lot! I tried everything else, but I think a new sim card might do the trick. I didn't even think about that.

[Q] SlimKat 4.4.4 and WiFi Reconnect issue

First, I've had this issue since Build 6.8. I was hoping a Clean Install using Philz Touch Recovery v6.48.4, which is the latest, and selected Wipe Data and select Clean to install new ROM which Formats /data, /cache, /system. I also wiped Dalvik.
Once completed I did the following:
Clean Install of Slim-d2lte-4.4.4.build.7.0-OFFICIAL-5979
I then installed
Slim_full_gapps.BETA.4.4.4.build.7.x-190
Rebooted and waited for SlimKat to boot-up. WiFi/Data both full scale. Everything Restored just fine and things are running smooth.
Then after running a few errands outside of WiFi Range, I returned home within WiFi range only to find out that WiFi had not reconnected. It tells a WiFi connection is available but will not reconnect to it. So I go into Setting and select WiFi and tried to manually reconnect. It says connecting and then goes back to Saved Connection without connecting. This same thing on other WiFi connections such as McDonald's or other open WiFi Connections.
I then do a re-boot and everything is back to normal. WiFi connects without issue and again things are fine and running smooth.
Every time I leave WiFi range and then return within WiFi range, the problem re-occurs. A Re-Boot and everything back to normal.
One thing I've always noticed when doing a Clean Install as stated above, all of my previously stored WiFi connection are still there. Same on Ringtone/Notification Tones.
With the problem I'm having, could it be something that is not being wiped/cleared out during the Clean Install process. Or wondering if it could be somehow that the WiFi Radio has gotten corrupted.
I have also tried different Kernels but again the result is the same.
Hope this is not too much of a noob question and I have searched about everything I can think of. Wondering if anyone has had this problem or have any ideas of what could cause the problem.
I really hope I can get this figured out. Thanks
If you don't have to manually reconnect and enter your password, then its not being wiped. (Or you are restoring it from a backup.) Have you tested it after the clean flash, but before restoring anything? What are you restoring and how?
It sounds like a Rom issue otherwise and you should probably ask in the rom thread.

First I don't know what I've missed wiping. When I say restoring, I'm referring to letting Google re-downloading everything from the Play Store.
I know the WiFi radio are in a different location but like you, when I do a Clean Install by formatting /data /cache /system and wiping dalvik, I wasn't expecting all the stored WiFi connections to still be there, but they are.
Its possible its being restored by Google's backup, but I don't use it myself so I'm not certain about that. Its also possible the rom may save the config file elsewhere. Again though, I don't use cm/aosp based roms so I'm not too familiar with any of their specifics.
Next time you try a clean flash, do not sign into google during setup. Instead go straight to testing wifi to see if it still remembers the connections. Do you have it set to auto connect to any open networks? If so you might want to turn that off.
Have you searched or asked in the roms thread yet? It might be a known issue or something a few others have encountered and know how to fix.

Ya I don't sign into Google at the initial start up after the flash because my WiFi is no able to connect. I will double check the auto connect feature. But I having this issue with other 4.4.4 ROMs also because I tired however on those ones I am amvle to toggle WiFi on but in advanced it has the region set to Europe and when I switch it to Canada it doesn't want to save the change
