No data after flashing a new ROM - Samsung Galaxy Nexus

I have a Galaxy Nexus with Android 4.1 using Simple Mobile (T-Mobile towers) but every time I flash a new ROM, my signal bars go gray And I get no data ( MMS, Browser, etc. )
It has to be something simple that I'm missing. What could it be.
I made a backup so all is well but I just can't upgrade.

Have you checked to see if your APN is configured properly after flashing?

I'm writing down all the APN settings now. I'm gonna flash and make sure these settings are correct.

[Q]Cant send MMS

After i flashed 4.0.2 radio, i cant send mms anymore.. I got the apn from my mobile provider (Telenor), but its stuck on "Sending"...
Any one ?
Is mobile data enabled? Do you actually have a data connection? Unless your provider gave you the wrong information.
I still have lots of problems sending MMS. 4.0.2 running Android Revolution 2.1.2, with the leaked 4.0.3 radios. It was a problem when I was still 100% stock, too. Pretty bothersome.
3G, WiFi (which I'm pretty sure isn't supposed to work with MMS anyway), nothing. Sometimes when I reboot and retry sending it will go, but mostly just sits in sending mode forever. Frustrating.
Might just have a defective phone. Go back to stock and lock it up and take it to your phone company

go back to your previous radio? or pick another to test.
btw, radios are location and carrier specific..
which is why it works better for some an not others..
ppl should stop referring to radios with a link to rom versions..

[Q] Regarding APN on cm9

Hi,
There are multiple apn's provided by my service provider,I'm using 2g data plan but somehow my service provider lets me in 3g network.
Now when i use a perticular apn on cm9 or any rom based on cm9,i get speeds around 384kbps,but when I use the same apn and setting with any gb rom or even froyo rom,it just doesn't work.Only the stock browser works.
I want to know if there's any tweak included in cm9 that lets it happen ?
Any ideas folks ?

Did you try to restoring the defaults via the menu ?
You can use APN Backup & Restore to clear all APNs,after that try to restore the defaults.

Common Flash Process
1. wipe cache/dalvik
2. wipe system
3. factory reset
4. wipe data
5. TWRP users wipe internal-wipes internal data that could corrupt something
6. flash rom
7. flash gapps
Do this if you have any unexpected problems.
If you want flash ktoonsez kernel but if you have problems follow the flashing procedure before posting about problems/questions
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.
Using ATT carrier.

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.

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.

[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.
Bump
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.

Note 2 No data coverage after 4.3 update?

Just upgraded to 4.3 today but my data services don't seem to function well. Can someone please help me?
Same problem here..
Looks to be an issue with TWRP, have either of you tried the latest CWM recovery? I was hoping to avoid it since my nandroid backup was TWRP (I'm honestly not sure if there's a difference) but a few posts in the main threads are reporting a similar thing.
EDIT: Nope, same issue, at least for omnirom.
I take that back, it does work.
Go to Settings - Network Connections - More Networks - Mobile Networks - Access Points Names
Check and see if you have the APNs from your provider, they usually are 3 ([Provider] Internet, [Provider] WAP, [Provider] MMS - in my case). Make sure [Provider] Internet is selected. When I usually re-install some ROMs, the WAP APN is selected by default and that will show me the 3G data icon but it will not let me access internet resources with my data services.
If by any chance you are missing the Internet APN, search a bit on the internet for your provider APN settings for internet access.
Hope this works.

It just acts like there's no SIM card at all. I don't understand it completely, but CWM is doing something that TWRP is not (or vice versa) and is causing this issue. Took my 7105T from virgin vanilla stock to the omnirom 4.4.2 nightlies yesterday and when I flashed from CWM the issue was resolved.
That said though, I'm unsure how this will affect omnirom's updates so I might need to switch to cyanogenmod. Shame, because I do prefer TWRP.
