[Q] Can't Connect To Mobile Data

Hi, I have an HTC Sensation running Cyanogenmod 9's June 14th Nightly. Originally I was running the June 15th Nightly, but I realized that my data was not connecting.
I was using WIFI and that worked perfectly, but when I was out of range, my phone attempted to connect to T-Mobile's network but failed to do so. The HSPA+ icon flickers on and off while the bars remain full and white. I was still able to make calls but I have no data connection. This was originally on the June 15th CM9 nightly. I flashed back to the June 14th nightly and the problem persists. I have also tried re-booting my phone several times.
I flashed the stock ROM with the 1.17 radios and Data worked but when I went back to ICS ROMS with the latest radios it didn't work. I also tried installing the latest RILs and Data still doesn't work.
Here is how my homescreen looks:

Any help would be greatly appreciated.

I had the same problem using my new Miui Rom (it's based off cm9 nightly) . I used titanium backup to clean out my Roms and just like you I realized that my data keep starting and cutting out. I backed up everything so i re-installed everything one by one until something called Key Chain 4.0.4 finally was found as the missing piece. You might want to install titanium backup and check for that app (key chain)

Mine did that when I was trying to use different APN's. The only one that allows me to connect is wap.cingular
You could check that, I guess. Otherwise, try opensensation and/or a different radio.

[Q] SMS won't send. Can receive/send MMS calls and Data

The Problem/Symptoms: I've been running a version of last CM10.2 for the past year. On February 20th, I was able to send a single SMS and then subsequent texts failed. I could still receive SMS, send/receive MMS, send/receive calls and send/receive data. If I toggle airplane mode/reboot I can send another SMS and then subsequent sms are undeliverable.
What wont work: Flashing to CM11 does not change the issue.
Disabling Voice+ does not change the issue
Factory Reset does not change the issue
Workarounds: Toggle Airplane mode
Switching Mobile Network to CDMA only (not permanent)
Change your number to a different area code
Going back to a Touchwiz based ROM
The Solution
net-cat said:
Alright. I think I've refined my process and it results in having a newer radio as well as not having to ODIN things or do dd commands.
NOTE: This isn't fully tested. When I did this, my phone wasn't showing the issue. I did this after doing my original procedure, but the GPS stopped working after I updated the radio from VRALF2 to VRBMB1. You shouldn't need to do the original procedure for this to work, but I haven't tested that. At the very least, the original procedure still works and this one can be used afterward if you need the newer radio. (GSM support...)
Ideally, we'll want to get to a procedure that doesn't use ODIN or dd. Hopefully this is a step in that direction.
Requirements:
A rooted stock ROM of the VRUCML1/4.3 vintage. I used Scott's Stock Rooted Knox Free VRUCML1 - 4.3 - DeOdex - V2. (Thread here.)
VRBMB1 AIO Flash, available here. (Thread here.)
I'm going to assume you know how to boot into and use recovery.
NOTE: Do NOT let the stock ROM install any updates.
Starting with my CM11 M3 install, I did a nandroid backup. (Recovery is CWM Touch 6.0.4.5, but I doubt that matters.)
Flash the VRBMB1 AIO.
Wipe data and cache.
Flash the stock ROM.
Boot into the stock ROM.
The reprovisioning seems to happen as a part of ROM's initial boot up.
Send a few text messages to test. (I sent them to Twitter.)
Launch the Maps application, turn on your GPS and let it get a lock. If you don't, when you boot back into your ROM, you probably won't have working GPS.
This would be a good time to back up your IMEI if you haven't already done so.
Reboot into your recovery, wipe data/cache and restore your nandroid backup.
At this point, you'll be running your preferred ROM with a less archaic radio than my previous post.
DO NOT UPGRADE YOUR RADIO. The moment I upgraded my radio, the problem came back!
CM11 M3 will work just fine with the old radio. I've rebooted several times over the last few hours and it still works fine. (Time will tell if it's a long term fix or not.)

Notes: There are threads for the S4 with this identical problem. All updated information I have seen is listed above. If anyone knows more please post as I am going to keep this updated. If this does/doesn't work for you please post and let the community know. Feel free to hit the thanks button if it works for you.

This exact thing happened to me. I tried many fixes with no luck. After hours of hacking around in settings, I found a ROM of verizon's 4.3 OTA update and flashed that through ODIN. My texts are working just fine again. Kind of a cheap method of fixing my problem. I wish I could have taken more time to find a fix, but I needed to be able to communicate with people that day.
Stock 4.3 is kind of lame:
-4.3 is killing my battery faster than ever. CM11 had me going for days without charging and now I've needed to charge everyday.
-Stock 4.3 is laggier/slower than CM11. It tends to stutter for me.
-4.3 came with a new boot loader which no developers have exploited to install custom ROMs yet. This leaves you stuck with Verizon bloat. I hate all these damn apps. Going to try to safe root & see if I can't do some cleanup work.
Enough ranting. Just wanted to let you know you are not alone with this problem. Hopefully someone will figure it out. Missing my cyanogen mod already

It seems this problem has happened on other phones also running Cyanogenmod. I found this thread http://forum.xda-developers.com/showthread.php?t=2654822
It looks like the symptoms have all showed up at the same time approximately. (February 19th, 2014). Still looking for a better answer than going back to stock TW...
Edit: And another thread http://forum.xda-developers.com/showthread.php?t=2659280 This one suggests its all AOSP roms. But it seems many people are unaffected... I don't understand why/how.

SO this is the current status that I know.
The problem happens for everyone with a 570/717 area codes + on verizon + running Cyanogenmod (possibly any AOSP) + while connected to LTE which started on Feb 20th (the day before KitKat came out offically).
Current Workarounds:
Switch to TouchWiz based Roms
Switch your radios to be CDMA only
Call verizon and switch your number to a different area code
I know the workarounds all suck but that all I know for now. Switching SIM cards won't work. If I anyone knows anything more please feel free to let me know.

I'm 717

I have still be unable to find a solution for this issue. I think I have to give up on CM and go back to a TW based. If I hear anything new I'll update the post but I don't have the time to be wasting on my phone at the moment. If someone finds or hears of a fix or if it magically goes away as it started, please post it.
And spread the word if there are any other ROMs that this is occurring on. It seems the pool of those affected is just too small.

I have already had to give up. Been running slows tw. I take it Verizon didn't get back to you?

Anyone try aosp to see if fixed yet?

Nope. Still having issues. Tried gummy and cm. TW based roms are fine. In 717.

What gapps are you using? I have been using the PA 0Day gapps. Going to try the gapps package from invisblek and see if that makes a difference.

It won't. It isn't software dependent. People who had already flashed builds prior to the 20th magically had issues starting on that date, so it isn't a problem with new builds, and it only happens to those in the 717-570 areas so it isn't a problem with AOSP code. It has to be a Verizon network issue, I just have no idea how.

I have run TW base roms almost 100% of the time. Prior to the 20th, I had flashed cm11 3 or 4 times to see if camera worked and was never on it more than a day. I also had issues where music in my sd card wasn't being found but it was fine on TW. Could it be the unified build causing an issue? I have no issues on Clean Rom 8, wicked sensations or old and slows stock based roms.
*Edit* I have installed Gummy and CM 11 with PA Mini Modular apps and the CM Gapps from Invisiblek, let it set up. I then shut it down, removed battery and sim and then put everything back in and still the same issue. 1st text message goes through, then the rest after that just fail. I tried regular message app, Hangouts and Verizon messaging. All same results. I go back to my CR8 backup and all is fine. It's bizarre because everything else seems to be working fine and is very fast & smooth.

It can't be an issue with the unified builds because going back and flashing an older build yields the same results. If you're willing to make the trade-off, you can set your phone to CDMA only. Texts will send, but you'll have no 3G or 4G.

I'm ok with using CR8, Beans or other stock roms. Can't see paying for LTE and not using it lol. Was curious to see how aosp has been coming along and sms was really the only issue I was having.

I was using masta's 10.2 build for over 6 months without even thinking about flashing new builds. The 20th is when the problem started for me. Upgrading to CM11 didn't change it. I just installed Hyperdrive and everything is back to normal.
I wish I could go back to CM but it just doesn't work in this area. And I don't know what I can do about it,

Basically. I've talked to a few friends who have worked for carriers and stuff, and everyone is stumped as to how something like this can even happen. Luckily I'm pretty much always in WiFi so I can survive on CDMA only.

[Q] No Cellular Data after getting back to stock

Hello everyone,
I was on Lollipop 5.1.1 Stock and not rooted then i decided to give rooting a shot. I downloaded Cataclysm and flashed successfully. everything was fine then i discovered that there is no Cellular Data connection. Rebooted and tried all possible things but didn't work. Finally gave up and flash Cyanogenmod 12. worked perfectly, nothing was wrong and cellular data was fine. After a while i wanted to come back to the clean stock lollipop so i downloaded and flashed Factory Image of Lollipop 5.1.1. Weirdly the Cellular Data doesn't work, i have no idea why or what may cause the problem. Please note that my Nexus 5 is from Amazon Germany. I doubt that there might be something wrong with the radio image ( meant for US models ?!! ) but i don't know really or have no clue what might be causing this !!!!
Any help is appreciated. Thanks in advance

FIXED
After spending 7 hours moving between different ROMs, i found out what was causing the problem of cellular data. The problem also exists after flashing stock image and Cataclysm. I noticed that on CM12 there was one option in the APN settings that was different from stock and Cataclysm. The MVNO type was set to None however in stock and Cataclysm it was IMSI. I don't know how or why would android change or decide that on its own and i also have no idea what does this option do. I guess that this may help many people who are suffering from the same issue ( also people who updated stock ran into same problem )

Don't know where you are but, every time that has happened to me a hands free activation fixed it.

[Completed] Nexus 5 Sprint. Data/APNs/3G/4G All broken

I have a Nexus 5, rooted, unloced. A couple of months ago, I started having data issues on CyanogenMod 12.1. Could not change APNs, couldn't really do ANYTHING about it. Tried modifying telephony.db files to no avail. Tried deleting them and letting new ones generate (they generated but it didn't help). Tried copying the telephony files from a working nexus 5 over and it worked for 5 minutes.
Eventually I flashed CleanCore and CleanCore 's radio. That worked BEAUTIFULLY and I had no Data issues for a long time. Well the other day, I went back to stock, upgraded to the most recent Nexus 5 Build and now no matter what I do, I can't get it to work. Tried reflashing CleanCore (nada) CyanogenMod 12.1 (nada) CyangenMod 11 (Nada) I am barred access to APN settings on ALL roms I flashed and NO changes I make stick.
I have a Nexus 5 that is no good to me unless I have Wifi. and Even then, what good is that?
Please help.

Is that likely? Ive done several reflashes, factory resets, flashed new radios.

Hello again,
If you couldn't make calls either, I would say your IMEI got borked. Although, doesn't hurt to check those numbers (dial *#06#) against the box the phone came in to confirm the numbers didn't change on you. A custom radio used for a ROM other than that ROM? Likely. But when matched with that ROM? Sort of falls through.
Or it could be data in another partition that is causing conflicting info, that isn't getting reset after any of the flashes. I have a phone that if you do not back up the Config partition between flashing ROM's, you lose all data access. So maybe something is sticking around that shouldn't be from the custom ROM's.
I would suggest asking around on the Nexus 5 forums (as I don not know much about this device), they should give some ideas.
Hope this helps.

Anybody have any luck getting LTE/4G and MMS working with Virgin Mobile?

Before I rooted I was running the Android 6.0.1 OSA update. Now I'm running CyanogenMod 13 Nightly and everything's working awesome except LTE/4G and MMS.
I feel like I've tried everything. With previous devices I was able to use the "Universal VMU APN Fix" to fix any issues but not now. I've also tried the "MVNO Slayer" with no success.
I've even tried pulling the stock build.prop from the stock image file from sammobile.com and making my own "customized" version of the VMU APN fix but I've noticed that the CM13 build.prop file doesn't have any cdma options in it so I'm not sure where those are stored.
And I've tried setting my APN settings manually through the settings menu but that doesn't work either.
Also, trying to revert my device back to stock using image files from sammobile.com results in my device getting stuck at the Virgin Mobile splash screen upon boot.
So I can't get 4G/LTE and MMS working and I can't revert back to stock. I'm worried I've screwed my phone permanently. :/
If anybody can provide some advice that'd be awesome. Thanks!

the weirdness in the first part of your post doesnt make sense as to why your phone is doing that unless the modem got screwed up when you flashed CM13 or if youre on a MM baseband. If i was in your position, i djust go back to square 1 and try again. Reflash the tarball, chainfires root tar, TWRP and let it boot. Make sure its all working fine, then flash a g900p ROM in TWRP and go from there. If you are seeing a virgin mobile bootanimation, they you likely flashes a ROM that wasnt built for your phone. Youre going to want to stick with ROMs made for the g900p specifically
if you want to revert, heres a faster dl of the OK4

I was able to get back to stock using the OK4 image you linked to.
I also tried flashing CyanogenMod 12.1 and applying APN settings to that without success.
So I guess I'm sticking to stock un-rooted for now unless anyone can help me get APN settings working for Virgin Mobile. :/

does virgin mobile use sprint as their backbone for it as a MVNO? If not, the reason you might not be getting data is the network lock.

I'm not exactly sure what a MVNO is. I know that Virgin Mobile uses Spring for it's mobile network. I was able to get my old device (Galaxy S3) running with CyanogenMod 11 on Virgin Mobile no problem. (After of course running the Universal APN fix)

an MVNO is a "cell provider" that exists only on paper just like straight talk. they buy their air time off other carriers and sell it as their own. I use straight talk but am using AT&Ts physical hardware. I think virgin uses sprint, but im not entirely sure. if thats the case, you should just need to use sprints APN settings. worth a try at least

Universal apn flasher for virgin mobile. Flash your rom then flash this zip. Works on 4.4.2,4.4.4 and lollipop but cant vouch for it on marshmallow as i havent updated my s5 to marshmallow to try it. Although it shoild work ok.

So I figured out what was wrong with my 4G/LTE. After restoring back to the stock rom, I realized that my 4G/LTE still wasn't working. I talked to the Virgin Mobile customer service rep for a little bit a figured out that my SIM card didn't support LTE. I had actually purchased my phone used via Swappa.com and I purchased the SIM card from Amazon. So apparently I got the wrong SIM card. Virgin Mobile sent me a new one and now I have 4G/LTE again! Still have to test it with a non-stock rom but I'm pretty sure it'll work just fine.
Thank you everybody for the help/suggestions!

Anybody that pays for a lte sim card should get their money back. If you call your provider they will give you one.
