No data. Why? - Nexus 6 Q&A, Help & Troubleshooting

Hi everyone. My mobile data isn't working. I was on euphoria 5-30 and was working great, but decided to change it up. Tried dirty unicorns, didn't like it, data was fine. I started flashing, chroma then aosip and then the latest euphoria. My data doesn't work. Everything else is fine, but my cell signal icon has a little exclamation mark and I have no internet. I restored my euphoria 5-30 and it still doesn't work. Any help would be greatly appreciated. I searched and found nothing of the like.

I had to restore to complete stock, copy the APN that worked, and input it on whatever ROM I use. Pretty sure the APN will be your issue. I think there's already a few posts about it.

Def APN

Thanks, both of you. I tried that, didn't work. A friend had the same issue and fixed it by registering through the network operator setting. That also did not work. I ended up flashing another radio out of desperation, and it worked. ?

Droid 4 and CM10.2 data issue

Is anyone else that's running CM10.2 on Droid 4 having data connection issues? Have you fixed them? If so, how? Does the code need to bake a while longer before data starts working?
I'm running CM 10.22010831-NIGHTLY-maserati
WIFI is working, but I can't get data to work otherwise. I did a factory reset and started fresh. I've tried flashing the ROM and gapps package multiple times. I wiped cache and Dalvik. I tried repairing permissions.
Any Ideas?
Thanks,
Marty

Tried that and still no love.
I think i need to update my baseband radio, but I can't find a more recent baseband version for the Droid 4.
I'm currently using CDMA_N_05.11.01P LTEDC_U_09.11.00.
Anyone have a link for a newer version or any idea how to get one?
Thanks,
Marty
Do u have the issue on stock rom slot? If so then take it back to stock with the latest utility floating around the forum. Check for system updates if there is one dl and install to make sure u have latest radio if problem persist then it's a Good possibility it's A coverage issue or hardware related problem..

Ok, here's where I'm at now.
I updated my stock rom. baseband is now at 5.25.00. Still won't work on CM10.2.
3g will work on my stock ROM, but not on CM.
I've screwed with the mobile network settings and I can't get any difference in results.
LTE works great with CM10.2, but as soon as I'm in 3g territory, I'm dead in the water. I can receive and place voice calls and I get text messages through the messaging app, but anything that requires an actual data connection, like google voice or the browser, it won't work.
Help!?
updated PRL, still no love.
In some versions i needed to add APN manually, then it would work. In earlier version i had the same problem that 3g would not work. Also problem with reception bars - it would always show like 1 bar or smth like this but would work just fine.

It already has several APNs set up. The one I have selected is: APN: vzwinternet, MCC:311, MNC:480. Most everything else isn't set.

Set adrift without data.
Day 10: I've run out of water. The sea gulls... they mock me... with their wings... and beaks... and of course their raucous calls. They are scheming against me. My only friend is the lone shark that circles me constantly. He's attentive like that. A bit forward though. Keeps trying to kiss me. I tell him "NO KISSES FOR YOU! Not until the second date."
Also, still no data.

First off, thanks for the chuckle
Secondly, you're getting no data at all? Are you on Verizon? If so, do you have LTE in your area? My personal experience has been LTE data is working fine but 3G has been REAL spotty. I did see dhacker on twitter post a new razr build with some 3G tweaks he was testing. So that is being worked on and should filter down to us when it does get figured out.

3G was working fine on 10.1, but is nonexistent on 10.2. It actually acts like it wants to connect to a roaming tower if I switch it to GSM, but it can only see it and won't pass traffic.
I could just go back to 10.1 or run stock, but my pigheadedness, that's a word now, won't allow it.
On the brighter side, I am learning a great deal more about my phone that I had previously known.
The problem seemed to rectify itself around the nightly build on 9-15 or 9-16.
I know I'm a bit late, but I always do the * # * # 4636 # * # * in dialer and I turn off the radio, set the radio to cdma/lte and turn it back on, usually it isn't letting all those other antennas run and it seems to pick 4G LTE faster in my experience.
I think it's a CM10.2 issue...
Hi, my friend with a Galaxy S3 is having the exact same data retention issues we are having on our Droid 4's, which makes me think this is a bug in CM10.2 on various devices more than an issue with our phones. I can get LTE data when I have service, but find that once I loose service, even for a moment, the phone then never re-connects to LTE again and just sits there with white bars instead. Toggling data or airplane mode seems to usually trick it into reconnecting to LTE, but it is becoming annoying to have to constantly check and toggle around to get data back. I've tried every nightly and the M1 and have found the issue remains through the 11/19 build. I've installed the ROM into slot1, I'm not sure if overwriting the stock ROM and using the stock slot with CM10.2 helps matters at all, has anyone had any experience with using CM10.2 in the stock slot instead of Sot 1?

[Q] Unable to activate mobile data

Hi community,
I'm a long-time lurker but just until today had the need to join this great place and bother you with a question. I already used the search feature and even googled this problem, which didn't quite helped as I'm still clueless.
Last nite, I switched ROM on my Desire C after being a long time user of Revolution MOD (thanks to @russell664) because sudden reboots started to affect my pone almost daily.
So I went ahead and flashed MiniJBProject (thanks to @penguin449) following the right steps (clean flash), rebooting after install in order to get WiFi enabled and everything seemed to work well until this morning, when I went outside my house and noticed Mobile Data doesn't work. I tried re-flashing ROM, switching between NOPE (thanks to @me4488) and Prometheus (thanks to @nikhil16242) kernels and frequencies to no avail (my pone doesn't go beyond 750 MHz), cleared Dalvik cache, fixed permissions in CWM, nothing.
As I said, WiFi does work just fine but Mobile Data is just not sending/receiving, I'm able to move the slider ON/OFF but get same results.
Then I thought my pone didn't like this specific ROM so I then flashed Revolution JB (thanks to @addictz10) again through clean flash, rebooted to get WiFi, and so on. Nothing. Still the same.
I feel like probably the problem has to do with CM10, since I didn't experience this issues with any of the Revolution Series ROMS.
Any further info you might need to shed some light, please feel free to ask. I'd really appreciate any input.
Thanks in advance.
By the way, I currently have Revolution JB in my pone.
I think you have to enter the apn settings for your carrier. Google for it. Go to settings, wireless and networks, mobile data, access point names, and enter your APN settings.

Most Roms will be able to use mobile data straight off the shelf if using a known, big carrier, for example T-Mobile, however if your using something more local, something not as well none, then you need to add the APN, if your on contract or PAYG with a different company that provides your network service, like TALKTALK uses vodafones, you need to add it otherwise it connects to vodafone, and uses vodafones APNs which, will not work.
Gotcha. Now I know for future ROMS. Thank you @penguin449 :thumbup:

[Q] Data connection

Hey there. I'm hoping that someone can help me out with this. A few days ago I updated to the latest rom from insertcoin. Since then I've had no data connection. Anything that requires Internet won't work. I've spent the day reflashing backups that I know are good but nothing worked. Tried different radios, checked apn settings and mobile data (which says I'm connected) without any success. In a moment of despair I reverted back to full stock hoping that it would solve the problem but again no joy.
At this stage I've run out of ideas which is why I've come grovelling to you guys. I couldn't find any solutions on Google, well nothing that helped. Everything looks like it's supposed to. Internet works over wifi but nothing works on mobile data. Any bright sparks out there with any suggestions ?
Cheers vinny

Thanks for the reply.I don't think it's the sim card cause I've tried it on another phone and it works fine.Hardware failure sounds more likely.I'm always careful when it comes to treating my phone.If I dropped it or something then I'd first think about a hardware problem,but nothing unusual has happened.Could flashing roms actually damage hardware ?
I one time did read about change the tel name in direct wifi to htc one that shold help someone wrote

[Q] Lost 3G after CM9/11

Hi guys,
This is my first post here but I've been abusing the search function pretty much all weekend for this issue.
Recently I updated my GT-P1000 to CM11 and the flashing went perfect and everything worked fine. Got all my apps etc sorted over wifi and everything was actually quite snappy and fast (for a pretty long-in-the-tooth machine).
Unfortunately I then took it outside and hadn't even thought to check if my 3G was working. It isn't.
I thought maybe it was a CM11 issue, so wiped it all and put CM9 (stable) on it but same issue; everything works except the mobile data.
I have reception and am registered on the network (Optus, Australia. Have just a data sim, no phone or sms capabilities) but for some reason my mobile data service says: Disconnected.
I've tried a few different modem installs from another thread but everything I tried it was all the same. APNs are exactly what they should be too.
If there's anything I need to add to help you guys let me know.
Thanks a lot!
Michael
Check if your IMEI is still 35xxxxxxxx
If it becomes 0049xxxxxxx you have a corrupted EFS. You need to restock to GB and check your IMEI. If ok, then flash CM again and check again.
Good luck.

Thanks mate, the IMEI is the 0049xxxxxxxxxxxx one so looks like that's the issue. I'll follow the restocking guide and see how we go.
Thanks a lot!
Michael
Well I restocked it which went well and the IMEI is back to 35xxxxxxx.
Unfortunately, still no 3G even though I've got the right APNs and everything.... Hmmmm...
-edit- also I notice the 'Mobile Data State' go on 'connecting' for a while before finally settling on 'disconnected' which it didn't do before.
-edit2- apparently I did have the wrong APN, my carrier sorted me out. I'm reflashing to CM9 to see if that was the issue there too.
Have sent an email to my provider to see if they can help at all.
Cheers
M
Just in case anyone landed here through Google my issue was resolved by restocking back to GB to reset my corrupted IMEI number.
Then I loaded CM9 (and actually on to CM11 now) like normal and everything is ok.
Make SURE you have the right APN set too. Sometimes they come across, sometimes they don't.
Cheers

Lost mobile data

Hi
After a lot of searching i've decided to start a thread about my problem. Here it is :
I've tried CM13, RR, Oxigen OS,Slim Rom and on all of them i've encountered the same problem, after a few days of usage i lose mobile connection (no internet), voice connection is working fine with a full signal. I've changes the SIMs , tried another SIMs,clean instals, numerous changes in the phone settings and the result is the same.
I'm pretty sure that it's not a faulty phone.
Im more curious if this is not a gug in the ROMS....
Any kind of input would be great.
Thx a lot !

Mobile Data are still a thing, but completely lost? Weird.
I had similar thing with resurrection remix rom and 3.2.4. Did full wipe with original oxygen OS and updated to 3.2.6. No problems anymore.
