I flashed my Nexus 4 at the beginning of the week and have been following the developers thread since then. Love it so far, great work devs. Problem I am having is (as the title states) my mobile data will not work what ever I do. Currently I am on Beta 3 Preview 5 with stock kernel and lastest TWRP. I have tried toggling the airplane mode and switching preferred network type to GSM/CDMA auto in *#*#4636#*#* and deleting the APNs and doing restore to defaults, but it still reverts to WCDMA preferred. MMS works (sending and receiving). My carrier is T-mobile, and the APN I have been selecting is the T-mobile US (epc.tmobile.com with no user, pass and server set, the rest of the settings I left on default). Any help on this would be much appreciated :laugh:
It's a preview version. It's kinda funky. I'd try reflashing. Took me awhile to get it so that I was Happy with it. Make sure it's a clean flash, wipe data, system, cache, and dalvik.

I understand that, I actually fully wiped everything when I first flashed it and had to do it 3 times to get Beta 3 pre 3 to work and flashed Beta 3 pre 5 two times as well. New user so the system didn't allow me to edit my posts earlier. I will try to flash again and see if anything changes
have you checked your APN?
I have just re-flashed my phone again, tested and gone through the phone info thing, deleting and restoring the APNs again, and still is having the same problem
Here are my current settings and info. I am lost as to what else to check and change in the APN. This current setting is from T-mobile's kb article that I found dating 2013
To add, I only have 3G, but when I try to search anything in chrome it displays the T Mobile 4G page, picture is attached as well
5.9
try 5.9 stable and fast

Hey, I normally wouldnt make a help thread. But Im at a total loss of ideas on how to fix this. My Nexus 4 has been running on AOKP 4.3 nightlies for a week or so perfectly fine. Today out of the blue I lost signal all together, so I went through the normal steps of checking if everything is in order. I tried to go into my apn settings to check those, but I just got a force close upon opening my mobile networks settings. I tried using the *#*#INFO#*#* menu to check my phone settings in there, but that force closed as well.
So I flashed a clean ROM and tried to check my APN settings. I was able to get into the APN menu this time, but when I would try to save an APN and it would just exit the setup screen without saving an APN. When I try and change the setting to anything (for example, GSM, WCDMA, etc) in the *#*#INFO#*#* menu it instantly resets to "UNKNOWN" I have tried flashing multiple new radios, and new kernels and nothing has worked. I'm totally lost.
Any help would be enormously appreciated. All of my previous phones were CDMA phones so I cant really just swap my sim into an old phone to use.
EDIT: Problem was resolved. If you find this thread because you have a similar problem, download the factory image from Google's site and flash that. That fixed it for me.

I've tried flashing a few of the radios from that thread with the same result every time, unfortunately.
Currently what ROM you're using? If you're on nightlies you should be aware that it isn't stable. I suggest you restore your nand backup if you have one.

Im currently on an AOKP nightly. Im trying to flash back to stock but Im having trouble getting it to do that for some reason too. Its acting like its been flashed, but it always boots up into AOKP again. Trying my hand at another toolkit before I start attempting to do it manually.

Flashing back to a factory image fixed the issue. Thank you!
Don't forget to make a backup. By the way I just got my 4.3 with CM 10.2 working with franco kernel.
I'm having a pretty serious issue with my ATT LG G2 right now. A couple days ago, without installing a new rom or kernel (though I was playing with some stuff in Titanium Backup +donate), my phone started having the following issue:
Less than 50%, by time, cellular access
~half of the time I DO have cell access, no data connection at all.
When I DO have data access, it is never LTE (I'm in an LTE covered area)
I cannot search Network Operators in network settings
Adjusting the Network Preferred Mode always resets after the phone eventually reconnects
WiFi is always fine, as is bluetooth
I've tried the following fixes:
Fix Permissions
Wipe Cache & Dalvik
Full format on system, data, all caches, and internal storage
3 different ROMs --CleanROM XE, PA 4.4, and Grievous
Stock Kernel for AOSP, Wootever and Stock Kernel on Grievous
Reflashing Modems
ATT reconfigured my SIM
APN was fine but I hand jammed a new copy of the original and selected it
changed settings>mobile network settings>network mode
ATT Tech Support sees no problems on the network end
I'm going to try restoring stock firmware tomorrow but I'm thinking my phone needs to be replaced. Any ideas or suggestions would be great.
Thanks!
Maybe the efs partition got corrupted somehow or its a actual hardware/provision issue

After reading into it, it looks like this might be the problem. Any suggestion for verifying a possible corruption? Seems like the way to see if it is broken is to go through the repair process...
Thanks!
Over the last several days, I've noticed I don't have any data connectivity on my LS980, running CM12. I'm on the ZV8 radio.
Things worked fine a few days ago--I'm not really sure when it stopped working, maybe when I installed the most recent nightly (150505)? I've tried toggling roaming on and off, wiping things, reinstalling, rolling back to both CM11 and the nightly where I knew it worked (150405), all without any luck.
I can make calls and text, and wifi works just fine, but I've got no data service at all.
Any suggestions on how to troubleshoot? I'm happy to do some digging, but I don't really know where to start!
Did you figure this out
Im having this issue also
Yeah, it ended up being that some of my radio settings were jacked. If I remember right, I switched Preferred Network type from CDMA/EvDo/GSM/WCDMA to CDMA + LTE/EvDo.
And then it started working.

I guess my settings got messed up also during my latest nandroid backup.
I had another working backup......So I just flashed the old working backup, then flashed the Data only from the non working backup restore.
I'm currently having issues where it seems that my APN settings aren't sticking. My cellular service & data work fine until I go into an area where I lose service & then when I reenter the service area my data won't switch back on. & sometimes it seems to lose data for absolutely no reason. But if I go into *#*#data#*#* & restore default APN settings & reboot my data works again. I'm on sprints network, using screwd rom, latest milestone build, the latest bootloader, & the latest radio. I've tried update prl. Ive tried update device configuration & when i update device configuration after it finishes I lose both data & cellular service until I reboot. I've tried performing "hands free activation" which also causes me to lose cellular service until after I reboot again. I've clean flashing rom & gapps, even tho I don't think its rom related. Reflashing the latest radio IMG. My next step is restoring the device to a google stock factory img & then starting all over. Anyone who has any suggestions I would greatly appreciate the help.
Upon further research it appears to be a bug in googles code affecting aosp ROMs. Doesn't affect all aosp ROMs tho. No known fix yet
So, I was using my phone at a mall. I stepped into a store and I noticed I had no more LTE. The signal was weak, so I thought it was just the building. So I got to a stronger area and restarted the phone, and still no data. I tried restarting several times and I tried selecting different APNs (I'm running 7/15 nightly of CM13). Eventually, I took the sim card out of my wife's iPhone 6S and the LTE worked fine. My sim card worked OK in here phone as well. But once I put mine back in, I have no data (not even 2g or 3g). I thought it was just my sim card, but then I can't understand why it works in my wife's iPhone 6S. Any ideas? I'm updating to the latest nightly of CM13.

My suggestion is to start fresh by fastboot flashing the latest 6.0.1 factory images. Verify that your mobile data/LTE are working. Then, install TWRP. I would also download a fresh copy if the CM13 ROM and verify the md5 is correct. Flash CM13 again and see if you have LTE again. If you don't have LTE after flashing CM13 again we know it is something that has changed in the ROM.

I think you're right. I'm going to have to do this. I got a new SIM card from Verizon and data was fine. Then once I went to work and entered into my office, which has a poor signal, I wasn't able to get data back (can still call and send/receive texts). It makes no sense as to why it won't reconnect after a reboot, but I guess this is the only option.
Yeah I agree. Fastboot flash the factory images to give yourself a fresh start. Confirm that everything is working on a fully stock build. Then root, recovery and flash. I would try a different ROM that is not CM based to see how your voice and data works. Let us know how it goes that way others in the forum who may run into this issue can read about what was performed on your device and know what to do to help themselves. Good luck.

So I flashed the factory images back onto my phone and I got data back. I guess there is a strange bug in the latest nightly of CM13. Of course, I haven't been able to go to an area where I have poor reception. Now I have to find a ROM that offers the LiveDisplay feature CM13 offered. I like my screen to be a bit colder than what Huawei calibrates their displays to.

I knew there was something in the CM13 based ROM's that was causing you to lose data. Also, If you use a custom kernel like Elemental or Elite you can control the screen colors and make it how you like it. Give Pure Nexus a try. It's a super nice ROM. The dev is awesome. He does great work. Maybe give Chroma a shot. Also, you could try Resurrection Remix. It's a CM based ROM but it may not give you the data issues. It's worth a try. Lemme know what works. Good job on getting the factory images flashed and getting data back too.
