Being crazy with network issues

Hi guys,
I usually don't create topics because there is already a lot of solutions to my problems if I search well, but this time I'm really stuck since 10 days, I don't know if it's a hardware problem.
I bought my galaxy nexus GSM version in January, I leave in Frane, I had some randoms data drops (1 per day) but I just needed to toggle airplane mode to get it back.
I never unlocked or rooted my phone (since the problem)
Here is what's happening. My phone only get network when I'm home. I turned off the wifi on my nexus, still have network, unplug my internet box, still have network.
So I go for a walk to see if it's still work, I just need to go downstairs and my phone loose the network. Impossible to call or be called. Toggling airplane mode do nothing. I tried to put another sim card (in fact 3 differents sim card from different mobile provider), not working. When I go back home, reboot nexus, everything works fini. I'm trying everyday to understand why my phone only works at my home.
Baseband : I9250XXLA2
Android : 4.0.4 IMM76I
Kernel : 3.0.8 franco kernel Milestone 4
What i did :
Reboot phone and take off battery/sim when the network is lost.
Bought another sim card
Rooted my phone and instal rom (AOKP Build 39, APEX)
Flash kernel (Franco kernel milestone 4, Fugu mod)
Flash baseband (XXKL1)
Changed ril with getRIL
Factory reset, wipe cache/data, wipe dalvik cache
I swear my phone is not fallen on the floor and did nothing wrong to get this problem
My nexus is going for warranty on Wednesday. If you guys have any ideas, or anything I did not already tried, do not hesitate!
Thanks!

Hello,
I have different problem. My Gnex is suffering random signal drops when my phone is on 3g network. On 2g network everything is fine.
Like you, I tried a lot of thing. Root, flash different roms, kernels, radios. Download getril, matched radio etc. Also tried to unroot and flash 4.0.2 stock rom. Nothing changed. Today, I went to Samsung service a they flashed new Samsung kernel... still the same.
So please, someone help us about problems that we suffer.
Thanks.

[Q] No data reception-Restricted Access Change

At this time last night (even less than 12 hours ago), my phone was all fine and dandy, and reception was where it supposed to be. Now I can't get any form of Data, and no SMS messages are going through. I bought this phone at the end of August and I am currently using the AOKP Jellybean Milestone 1 (problem persists on stock ROM). I've tried pretty much everything I can find, short of bringing in the phone to a Rogers outlet... I'm pretty much at the end of my wits here. Help?
EDIT: As of right now I'm running some Emergency bull**** on Kies.
EDIT2: which failed.
EDIT3: I should probably note that I'm using Rogers.

Didn't work.

I'm also having issues with data drop! The network signal will be full and sometime when I wake the phone , there's no data connection.. Also happens when I answer the phone ...network mode is set to LTE/GSM/WCDMA running AOKP MILESTONE 1 JB... also I updated to the latest baseband and still having issues... It doesn't happen all the time but its happening enough to bug me! Any help is appreciated!
And forgot to mention when I reboot the phone I get the "restricted access change" and the clock resets to a different time... I have to go to settings and click on the automatic thingy for the time... And then it resets

[Q] Bad network connection after upgrading to CM 10.2

Hey guys,
I recently upgraded my Rogers Galaxy S3 d2att from CM10.1 Nightly 02/12 to CM 10.2 and have no longer been able to get the usual H+ connection. I now have either no letter or an E beside the signal bar. I did the following:
Dirty Flash 10.2 through Recovery Menu
Delete cache, dalvik and data in recovery menu
Couldn't get 3G, 4G or H+ Connection so I dirty flashed 10.1
Installed latest d2att rogers modem, installed latest bootloader, neither worked
Flashed back to CM10.1 Nightly
Can't get previous H+ connection on CM10.1 Nightly
I'm getting the worst headache trying to solve this. I'm more than willing to revert back to stock to try and get this working properly.
Thanks!
UPDATE:
I found out my IMEI was deleted while flashing. Does anybody know how I would get this back?

First off, how did you get cm 10.2

Try going back to stock by odin. That should work. And how did you get cm 10.2?? Can you give me the link where you downloaded from. That would be great.

Are you sure you don't mean CM 10.1.2? I don't think CM 10.2 is available for the Rogers or AT&T Galaxy S III yet...if it is please link to it.

Yes sorry, you're absolutely right! I still have service on my phone but I cannot even get 3G signal.

1. Check if Access Points are correct
2. Check if you lost your IMEI (normally if you still get service but not mobile data beside edge, your IMEI will show as 0)
3. if the above aren't true, have you try flashing different nightly/stable or different roms?
and if your imei was deleted
you need to inject your imei again
first, take out the battery, beside the battery there should be serial numbers and imei numbers
secondly, you need SGS3 NV Gen and NV item reader & writer OR you can also use QRST though the process is a little more difficult (I don't think i can distribute the files here, and QRST you can google it)
as for SGS3 NV gen and nv item writer, you just need to copy and paste your imei to SGS3 NV Gen and it'll write to a text file, then all you need is to use NV item writer to connect with your phone and upload the file.
oh and you need to revert back to stock rom because the phone needed to be in RM + Modem + something mode lol... which is located in one of the secret menu .... i believe it was *#7284#

I followed your steps. The IMEI was injected successfully but the ERI is still showing 0. How do I fix that?
Or, how do I get it to re-register on the network with the IMEI in place?

Samsung Galaxy S3 (d2att) Poor or no Service
I'm having the same issue - or so it appears. my IMEI was also erased and I restored it using the method described above. That solved the issue of not being able to connect to the network at all, but now my connection last 3 minutes at best. I start off with LTE, then 3g, then g, then no letter at all and through that all, making/receiving calls, sending receiving texts, and even accessing the internet is only doable the first 3 minutes or so. After that, all if gone.

I've tried various CWM versions, ROMs, and even Odined back to stock but still have the same issue. I ruled out the possibility of it being a SIM issue by placing my SIM in another phone. Service worked beautifully as expected. I took a working SIM from another phone and placed it in mine and had the same poor signal issue.
I've tried a good deal of troubleshooting methods and am seemingly stumped. I'm sorry to see that others are having the issue but I'd like to help however I can. the only thing I can say for certain is wrong at the moment is that my Serial Number seems to have been changed and no longer matches what is written on the phone....could that be the issue?
Current Serial number is displayed in about phone as: 1f03dbad
Hopefully, this provides some insight and someone a bit more knowledgeable than myself can help us find a solution.
If you need anything else, let me know and I'll do my best to provide it.

Please help I have the same issue, I have flashed back AT&T official ROM, but no 3G signals and weak phone signals. Did you guys find a solution? How do I check my ERI?
Please help if you have a solution.

I am having the same connectivity issues. I had to restore my IMEI earlier this week after a dirty upgrade, and then restored to several 10.1.x versions and back to 10.2, though this did not help. I did a stock restore and then rooted again, as well as restored 10.1.2 and nothing helped. I also dirty flashed beanstalk latest build, 2 builds of paranoid android and nothing worked.
Sometimes I can get on LTE or HSPA+ for a few minutes after turning data off and on, but this resets. I have also tried several APN settings, the ones provided by cyanogenmod as well as reconfigurations.

I having issues with CM10.1.3 ,I searching and finding this on the Google plus internet page of CM talking about compatibility of our phone with the news CM ROMs:

This is irrelevant, the new bootloader was added into the recovery ROM so there is no need to downgrade the bootloader. I did just in case to see if my issue would be fixed but as expected it was not.

[Q] How to enable network data after installing Cyanogenmod CM11 M7?

I tried flashing a custom ROM for the first time last night and so far I am really loving it. The only problem is, after flashing the CM11 M7 ROM it wont access any data over the cell network. I did figure out that if using Titanium Backup I restore my stock ROMs 4.3 data only from the Phone/Messaging Storage (SMS/MMS/APN) then reboot the network data does work. However, this causes the SMS to cease functioning. As soon as any app (default messenger, hangouts, 2-3 others I tried from store) tries to open it immediately crashes. Interestingly, it also will not allow me to restore my SMS records using Super Backup at this point. If I go back into Titanium backup then wipe the data for this process then the SMS starts working again, but all the old messages have been cleared, and as soon as I restart the phone the Network data is not working again.
Any ideas on what to do? I am wondering if maybe I need to adjust something in my APN profile, though I have absolutely no idea where I would get the information to do this.
This is what I am working with:
Phone: Samsung Galaxy S3 i747 (AT&T) -- [though currently I am using a TIGO sim card in Guatemala, wonder if this could have anything to do with it? was not a problem prior to switching the ROM though]
ROM: cm-11-20140608-SNAPSHOT-M7-d2lte.zip , the Cyanogenmod CM11 Snapshot lte release from yesterday
Android Version: 4.4.2
Baseband Version: I747UCUEMJB
Kernel Version: 3.4.91-cyanogenmod-g9b9605b8 [email protected] #1
Anyways, only having one or the other of my network data vs sms working is not really an option for me, so need to figure something out.
Thanks!

I apologize in advanced for not answering your question.
Is your issue that you cannot even get a signal with CM installed? I am also having the same issue.
Did your phone get signal/mobile network with the stock ROM? I am unable to find out if mine will work right now because it would take me a few days to download the stock ROM image...
Will be following this thread...
Mike

Have you checked that the APN on your phone is the right one for your carrier? Google search apn tigo guatemala galaxy s3 Many useful results will come up.

Ok here is how this played out. I did just need to reset then re enter the apn info for tigo in Guatemala. I actually managed to pull this info out of my pre flash backup from when I was using the stock Rom, then wipe the data for the process mentioned. This restored sms functionality and I then was able to manually enter the apn info (if anyone needs the Guatemala tigo apn info just post here and I can grab it when I am next at my cpu). I find it interesting that the apn info was automatically present and correct when I was using the stock Rom, but when I flashed cm11 over it was not there.
Just arrived back in the US and popped in my AT&T SIM card, everything worked fine right off the bat with it.
In answer to your question, after flashing cm11 I did have signal, but only for calls and sms. The data component of the network was not recognized.

"Mobile Network Is Not Available" Gio running CM 11

This is my first post here, so apologies if this isn't where my post belongs or I screw something else up.
So, I had a previous CM on my phone for awhile, whichever used 4.0.4 as memory serves.
Decided to try a 4.4.x based rom, and found a 4.4.2 rom which actually has a working camera, which seems to be always the problem with roms for the Gio.
I *thought* everything had gone smoothly, only to realize that my phone had no connection to the Mobile Network wasn't working. it took me a moment to figure out how to get that connection to work as this had not been a problem previously. my problem is the connection seems to be forgotten, on occasion, with little or no warning that I can neither make or receive calls nor SMS. Forcing me to search for the network, and reconnect.. shouldn't this happen automatically?
I hope I've provided enough information to be useful, if not I'd naturally be happy to provide what I can.
Thanks!

I am using CM11 RC9 also meet the same problem, after a soft reboot then it show "Mobile Network Is Not Available", everything is work except using mobile network to surf the internet.
And there has another problem, sometime Wifi suddently no data transfer, I have to turn it off and turn on again, and it's working again.

A newly flashed rom or sudden reboots activates 3G network mode. So switch to 2G in these cases.

It's a 3g/2g phone and 2g coverage doesn't seem to be as good in this area. I could understand if I were in a low-coverage area but it seems to be intermittent, it will be working fine, and then stop, then it will have trouble finding a network after searching multiple times. even then, again, should it not be doing something like this automatically? It shouldn't require manual intervention every time I lose signal.

Okay, I was out with the phone today and it was constantly losing the signal then not being able to find any networks "error searching for networks" so I think this rom is not really in a good place yet, I'll have to try my luck with something else.

Looks like it was a noob mistake on my part, I think the baseband was changed to an American S5660 one, namely XXKS2
I was able to apply one from an older Canadian S5660M rom from samfirmware.com, namely UGKG3.
So I *think* it's sorted, but I'll keep you up to date.
