Cannot Connect to Mobile Data

Good day Gentlemen and Ladies,
So, as you the title states I cannot connect to mobile data (3g). (Before posting this I had done my research trying to find a solution and I cannot find any solutions) Let me tell you a little bit about my Galaxy Nexus SO originally when it was purchased it was a yakjuxw and I flashed to stock yakju-4.0.4 by this methodI can not link the video atm as I am a noob here) (I am sure that I did not skip any steps). I updated to android 4.2.1 all OTA updates and since that day I cannot connect to mobile data. I am pretty sure this is a software issue unless its a coincidence that my device fails on me at this point in time. Everything worked fine before i flashed it. I have tried going into *#*#4636#*#* and making sure my network type is correct as well as the radio band as automatic. I tried rebooting the device, I turned on mobile data and waited for +2hours for it to connect and nothing. I am sure I did not reach my mobile data limit as it is the beginning of my billing cycle. So, if anyone has any solutions would you be kind enough to give me a link or instructions on how to fix this problem. I recently also got double my data free of charge (from my provider) and I can't even use it Lol... Thanks!

1. Settings -> About Phone -> See your baseband? Does it exist or does it say Unknown?
2. Attempted to reset APN?
3. Tried your SIM card in another phone? Does data work on that phone?

Man you are a genius thank you. It was an APN problem. I think when I flashed it the server # and port # went missing or something so I added those and 30 seconds later it is all working! Thanks again my friend. And for anyone who has this in the future you can access you APN settings->more...->mobile networks->Access Point Names (and APN vary on provider)

2. wipe system
3. factory reset
4. wipe data
5. TWRP users wipe internal-wipes internal data that could corrupt something
6. flash rom

Possible Data Fix
Alright, for anyone having issues with the CM10.1 "pre-release" builds (official or otherwise) not allowing you to keep a connection, here's how to fix it:
Download one of the modem files for your device (read!) in the OP of the modem thread. Any of the options will work, pick the one you want.
Keep that ZIP on your EXTERNAL storage. You need to be able to find it from CWM/TWRP.
With CM10.1 running, disable data from System Settings > "More..." (under Data Usage) > Mobile Networks > "Data enabled" (uncheck it)
Reboot into recovery. (Long-press Power, "Reboot", "Recovery", [OK])
Flash the modem from step 1.
Clear Cache and Dalvik Cache.
Reboot back into CM10.1.
Wait 30 seconds!
Enable data from System Settings > "More..." (under Data Usage) > Mobile Networks > "Data enabled" (check it).
You should have data within 10-20 seconds!
If this doesn't work, you might need to reset your APNs to default. This will only happen if you make changes to your APNs, so go into the APN list and press the menu key and hit "Reset to defaults". Then start over at step 1.
To prevent this problem, you should disable data before shutting off your device. You can enable it 30 seconds after boot and it should work again. If you get stuck in the "disconnect-loop", repeat these steps.
Themes
Sense 4 10.1 theme (might work for other roms)

1) Do you mean LTE, HSPA(+), or something else? HSPA(+) doesn't seem to work very well under 4.2 conditions.
2) Who's your carrier?

The same model of phone (well, more or less) is used for several Canadian carriers, which is why I'm asking.
Just to confirm: are you getting a data connection on something other than LTE? If so, that narrows down the number of things that could be wrong - my two immediate guesses would be that you have the wrong APN set or you have the wrong network type set in either Settings -> More -> Mobile Networks or in the Phone Info menu you can get by dialing *#*#4636#*#* (these are both known to happen immediately after flashing something).

There it goes , that did the trick thanks for the help. Now my GS3 is working perfectly with the update.

Are you getting a 4G logo on your bar? I cannot get anything but 3g,H, and H+. Mobile network setting set to LTE/GSM/WCDMA. any help would be nice, I seem to mainly get H+ and sometime switches to 3G.

I'm going to offer the same suggestions: check your APN settings (that seems to be the big one for AT&T) and check your network types.
I assume you've had LTE coverage under other ROMs?

Are no files displayed at all or is it just displaying differently? Once I updated, it moved all my files to the folder/0. Check there and it should display your folders as on 4.1. I believe it has to do with the multiple user functionality.

Its a preview. Its not supposed to work. The preview I released is basically just a screenshot of what's to come. I haven't even release a full ROM yet.

Emoticons
The emoticons are now implemented in the keyboard, is there a way to flash em over or download em. If anyone else has this issue let me know.

I can't get Portable Wi-Fi hotspot to work?
any ideas, has anyone else tried it?
is there a way to submit bug reports for nightly builds?

no data connection at all now via the radio.(but the phone can receive & make calls) I followed the steps to check it as posted by another user above....but still tryin different modem files.

did you try the fix in the op?

CM10.1 on Bell Galaxy SIII
I installed CM10.1 yesterday. Most of it works flawlessly. Had to uninstall and reinstall some apps (Google Play Magazines) for example. But almost all of them work as is.
I do have a problem with cell data connectivity. I need to reboot a couple of time to make it work. When it does, it works flawlessly. But when it doesn't there's nothing you can do. And it's random. You reboot, it may or may not work. If it doesn't, you reboot until it does. I also didn't have H+. I changed my baseband version and I now have H+.
This very much like a limit condition on init sequence. It was working with CM10 so I guess the components initialization sequence changed a bit for CM10.1.

Ya that's what I've been working on. I finally did get it working (for now) with the modem 3rd down on the list.
Does CM10.1 have a LTE icon that appears when LTE is being used, or does it always just say "4G"?

This is getting to be my experience. I just tried a few different modems, and finally got it to work...then I decided to reboot...and it stopped working. A few reboots later, and it still is down for the count. I guess I'll try another modem.

Impossible to get network operator

I flashed CM10.1 on my S3 and had the same problem as others where data was intermittent. It worked for some time and after one nightly, I lost my IMEI. So I got back to stock, used the procedure with QPST and got back my IMEI. I got back to cm10.1 and unsurprisingly, I had a hard time having data. But worst off, I had a hard time having cell connection anymore, not even voice or sms. Tried AOKP without any luck. Tried different modems, not luck either. Now I went back to stock and still doesn't work. There's something that is not resetted between flash of ROM that keeps messing up my connection. I also found out that only one network provider is ever found, one is Rogers Wireless (I'm with Bell), or one is EXT. But never any other provider is ever found. And also in *#*#4636#*#* under phone info I can'T change the radio band like I can on the phone of my girlfriend.
So there it is. I'm stuck. I don't really want to buy another phone. It is a software issue for sure. But how can we solve that? Is there any way to restore the EFS to factory default? Could it be buried there? What is the ERI? Could it be that? My stock ROm says that it can't get the ERI version.
Any help is welcome.

my stock telus ERI is unavailable but i think thats normal... i have no problems
from what i understand imei and apn settings are the things to check into

IMEI and APN are good. IMEI will get me data, but I can't even get a cell connection now. No radio at all.

whats your radio band set to?
if i set mine to anything but automatic it wont find networks like yours..
*#*#4636#*#* dont work on my telus s3.
i use a different method
*#197328460# then
UMTS > Debug Screen > Phone control > Network Control > Band selection >
Automatic...
beware what you change in here as there is no return to default

Neither of the two works. *#*#4636#*#* was working with CM10/10.1 and AOKP. But not with stock. And the one you suggest after is not working either.
But I remember going ot *#*#4636#*#* before flashing stock rom and I wasn't able to selet any band. On my girlfriend's android phone (HTC) I can.

if it were me.. i would try reflashing stock again... after flashing stock do a factory reset thru recovery... seems to help for clean stock setup.
if still no network i would check that band selection is set to automatic.
maybe someone else with more experience would have a better idea.
you mentioned you changed your band selection and now cant change it back.
i dont think flashing stock changes this.
i think that might be your problem.
ifso you first need to fix phone to use *# code... i have no idea why its not working
it works on my stock telus 4.0.4 and 4.1.1
maybe bell blocks from using *#code?

Thanks for your answer. Really appreciated. I've flashed so much time that I don't see the point of doing it again. I also had, at some point, to inject my IMEI and it worked with QPST.
What I find really strange is that a stock reflash doesn't put everything back to when I bought the phone. Funny thing, after the flash, it knew what my Wi-Fi router password was! So obviously there are some part of the config that is not overwritten. Which I find odd.
I also started playing with the service menu and found a lot of settings for the radio band. No luck yet.

Your WiFi password could have been restored by google just like it puts your contact info back.
If you are doing a Odin to stock that should wipe it clean.

This thing is so strange. There's only one network that my phone can see now, and it is 302720. Bell is 302610. No other network is visible. And since I'm with Bell, then I can't connect to 302720. I'm in for emergency calls only. That's why I thought it may have to do with radio. But it seems Rogers (302720) and Bell use the same bands. A channel maybe? But this should be all automatic! It's a pretty stupid bug let me tell you!
Maybe a SIM card issue? That would be quite a coincidence that it happen exactly when I'm playing with ROMs...

Ah that's a good possibility. I didn't know it was saving passwords as well.
So if it wipes clean, how come this bug stays? There is obviously something that is not wiped and overwritten or else it would work.

When you go to info about your phone, in status you usually have your IMEI number. It'll show 0 if it's corrupted. Or sometimes it's a generic IMEI dans is used when the real one is unknown. It's 049 something I think.
Without an IMEI number you can do phone call. But you'll never have a data connection.

[FIXED] Mobile data doesn't work with custom ROMS

Hello,
I purchased the new Nexus 7 LTE last friday. The very next day I unlocked, rooted, and installed the ElementalX kernel (with the stock ROM) . All worked well.
Sunday I tried installing a ROM (IceCold). It ran fine, and I was on wifi, so everything was working. Until I go out of my house. Mobile data was not working at all. I later reflashed stock, and did a factory reset. Mobile data worked again.
I thought it might just be the ROM, so I decided to instead flash P.A.C Nightly 4.3.1 with default kernel, and again, same issue. The mobile data icon is grayed out, unless I connect to wifi, and then it goes back to the blue color.
I have tried everything I could think of:
Restore stock recovery, kernel, and ROM.
Help would be greatly appreciated. Thanks ya'll.

Does no one have the same problems? Could this just be me missing something?

You are probably using a rom for flo Devices that do not have lte or 3g connectivity. Only use roms from the "nexus 7 (2013) LTE Android Development" forum!
Sent from my Nexus 7 using XDA Premium 4 mobile app

It could be that the custom ROM you are trying does not include the APN for your carrier. Go to Settings -> More -> Mobile Networks -> Access Point Names. You will need to find the correct APN settings for your carrier. You could copy them down while you're on stock, or look them up online.

No, I checked this. The first ROM I tried installing wouldn't install because of it being for flo devices. However the next two were both made for deb devices. So that wasn't the issue. Thanks though.

This does make a lot of sense, could it be it's not reading the Sim correctly perhaps? I'll be sure to try this when I get the chance.

Most APN settings are easily found with search of the carrier name and APN. You may have to enter these manually.
Did you try mobile data before rooting and installing a ROM/Kernel?

Data worked before during stock, and when I had a custom Kernel with the stock ROM. So the cause definitely had something to do with the ROM. After I reset everything (relocked and unrooted) it still works. I am redoing the unlock and root as I type this, and I will hopefully get a ROM installed and check to see if the APN settings really were the problem

Well that's good news. The only reason I asked was to make sure it wasn't possibly hardware related.

Can't make calls out (Random only on network mode WCDMA/GSM (Auto Connect)

Hi.
I have a Samsung Galaxy S3 T999 model on carrier T-mobile. Lately the phone has gone nuts and will get stuck on dialing out and will never make the call. Everything else works fine. Sometimes I have to soft reset, pull the battery and that will fix it for a call or two, then it will get stuck again. I have contacted T-mobile about this over 5 times and none of them can help. We tried to change the sim, reset the account. Etc and nothing. I have reset the cache, factory reset and even put in a good working sim card from another phone and the same problem comes up. During my latest troubleshooting I have narrowed it down to where I switch "network mode" to GSM only and that can make calls out all the time, but the data stays on E (which then I can't use the internet because it's so slow) When I switch back to auto I am sometimes able to place calls again, but only a few. After I test a few calls and leave the phone for a few minutes the phone will get stuck back on not making calls out and just saying "dialing".
Has anyone had the same problems or know of a fix? Currently I have been trying to flash the modem to different versions to see if that fixes the problem. The first two modems I have flashed did not work and came up with "unknown baseband".
If anyone can help I greatly appreciate it.

This is a known issue with 4.3.. What firmware are you on? Assuming you flashed the correct baseband for your device, the 'unknown baseband' message sounds like you are in 4.3 but what build? You can't flash any modems successfully less than 4.3

I was previously on 4.1.2 when the problem first started. I updated it to 4.3 and still the same problem.
jss15j.t999uvuenc2 build. (I put this one back on last night so at least I can use the phone today when I am at work)
I was just hoping that the device didn't go bad when it was on 4.1.2 because it was working just fine before the problem started.

Was it official update to NC2 by OTA/Odin or you just flashed a ROM?

NC2 was OTA. After doing some searches it said that OTA could of been corrupt, so I went and downloaded KIES and did a reinstall that way.
When I upgraded to 4.3 I tried that default baseband out and had the same problems. That is when I was searching on google and came across this forum and also the thread about flashing modems.

Network Mode current set to GSM (the only way I can make calls out without the problem occuring)
WCDMA/GSM (Auto Connect) is what it should be on so my data is at 4G, but the calls is the problem here

I am not sure but can you check the settings of the Dialer to see if there is ways to choose Lookup providers ?

Nope don't see anything in the dialer about selecting a provider..

Its supposed to be something about Choose Lookup Providers. At least that's the way it is on AOSP.

I suggest Odin flashing the stock NC2 firmware and then factory resetting from stock recovery. (Backup first of course!) If it is still an issue, it will most likely be a hardware problem. From what you have said so far, I believe that you will find this to be the case. Could've been due to damage from a drop, or even overheating at some point. Or it could just be that its simply due to hardware degradation over time.
