I did a search, but wasn't able to find any relevant threads. So if I missed something, please point me in the right direction.
My problem is that earlier this morning, my data ceased working. The notification bar shows 3G (sometimes even 4G), but I cannot get anything to load or refresh. The data arrows are indicating that while data can go "up", it isn't coming "down". I'm not sure what happened, as I wasn't doing anything out of the ordinary when this happened. I've got a decent signal in terms of bars as well, at least 2 or 3. Even given that, the data connection does appear to drop and then come back a few seconds later, but the behavior is the same: no internet.
I am S-OFF, global radios I believe, and when this first happened I was running the "le n00b" CM9 kang (which I've been running since yesterday morning with only intermittent data drops and no other problems). After a while of no data, resetting the radios via airplane mode toggle, a reboot, full shut down and restart, I restored a nandroid of the sense-based Vigor360 ROM, which had never had any data issues, but the same behavior is happening. Notification bar shows a decent signal, 3G/4G, but no data. After that, I powered down and pulled the battery, sdcard & sim card, left them out for a minute, put it all back together, powered back up, but still no data.
tl;dr: notification bar shows 3G/4G and decent signal, but I'm getting absolutely no data.
I've confirmed with a co-worker who's also on Verizon that their data is working, so it doesn't seem to be tower/network related. Anyone seen anything like this before? If so, what's the prognosis?
UPDATE: I was in Vigor360 with no data, and kept digging around XDA's wonderful search function, and found someone with a similar issue (though nothing about 3G/4G being in the notification bar) and they updated their PRL via *228. I did that, data seemed to come back. So I took a chance and restored my "le n00b" CM9 nandroid, and so far I've got data! Editing this post using that connection right now! I'll update further if I drop data again or discover any new relevant info.
the *228 wont do anything for us now that we have 4g and the sim card updates the prl when there is a new one. that was the old way to force a prl on 3g only so i think that was only a coincidence that data came back.
you might have a bad sim card. what you can do to test is put it in wifi mode and surf the web. if that works then its not the radio.
thing you can try to do:
remove the sim card and boot the phone. wait for it to fully boot and it say there is no sim detected. turn of the phone and put your card back in. then boot into recovery and wipe dalvik cache and boot the phone like normal.

Perhaps, but that was the line of demarcation between data not working to it working. Plus, the data speed seemed even faster than normal for the respective signal strength. Either way, I'm just happy it's working.

Thanks - I'll keep this in mind if it happens again. I was able to use the internet normally on wifi.
check your APN
You probably know -
You can always RUU back to stock to have a working phone

Hi all,
This is my first thread here, but I'm not too noobish when it comes to technology. However, if I'm breaking a forum rule or you need more information, please ask.
I have a GNex with Verizon running 4.0.2. I am rooted and have flashed Clockwork Recovery and in the past flashed MIUI; however, it was a little sluggish for me and at the time I didn't have time to fiddle with it so I restored to a Nandroid backup I had created before flashing. As a side note, I haven't been able to get CWM Recovery to work correctly in the past as it will flash correctly (using the Galaxy Nexus toolkit) and I can boot into it directly after flashing, but after booting into Android, restarting, and attempting to boot into recovery it will give me the android/red triangle error. Not sure what that means, but if I need to use it I can usually boot into it without flashing.
Anyway, on to the meat of the problem here. Earlier today I took my phone off of WiFi to use LTE here (Bay Area, CA) but my phone wouldn't connect to the cellular network. Nothing I haven't seen before; I cycled airplane mode and the "data enabled" option and restarted to no avail. Upon rebooting, I got the "Unfortunately, the process com.android.phone has stopped" twice in a row. At this point, no bars displayed at all. Confused, I looked into Mobile Network Settings and under Network Mode it oddly stated that the preferred network mode was set to WCDMA preferred (specifically, GSM/WCDMA preferred). I can try to set it back to LTE/CDMA but it will only reset it back to GSM/WCDMA.
WiFi works, but as soon as I turn it off it will revert to the greyed out bars inside a triangle. As I type this now, there are currently two bars, but they are grey and of no use. I just tried to call someone, and the call went through, but the double "com.android.phone has stopped" dialogue box came up again
I suppose I am willing to do a stock reset, but I'd rather not due to my large amount of music, video, etc on my phone; plus, it's just no fun to throw in the towel and do a reset
Any and all help is welcome, and like I said if you need more information please ask. I googled this issue and no similar threads popped up on any forums, so I hope that if/when my issue is resolved this will serve as a guide to others who experience this issue. That is, assuming they do; my tech issues are all too often unique to my own horrendously bad luck.
gracias, dudes.
Bump since it was buried.
Now fixed with a wipe/reset. Initially I wiped/reset and restored all apps/data (including system) with Titanium Backup, but after the system data had been restored and I rebooted I encountered the same exact problem. I wiped/reset again and just let the Market redownload all my apps and the problem has since stayed away.
Any ideas on what exactly could have caused the issue, though? I'm curious.
I updated to the latest nightly (9/22) to try and relieve this problem to no avail. I've been running CM Nightlies on my P4 since they've been available. I always manually download them since, for whatever reason, Rom Manager seems to detect my device as the P4-wifi. I assure you the 3G (HSPA) modem works. I have a SIM slot, with SIM that has activated service (UMTS/HSPA). My cell phone is on the same networks and it picks up signal from my carrier fine.
With that out of the way; My issue:
Two days ago, I was leaving my house to visit family, and I wasn't going to bring my charger for my Tab, so I put the device in airplane mode to conserve battery. In hindsight, I should have just asked the device to power off, but that's besides the point. When I tried turning off Airplane mode, the cellular network did not become available again; this situation has not changed since.
What I've done: Rebooted the device after switching out of airplane mode, re-entered airplane mode and left it again, updated to the latest CM. I've opened my tab and reseated the connections for SIM and antenna (at least, the connections I can reseat, I have), I've also completely disconnected power by unplugging the battery and reconnecting it. Additionally, I got into some of the hidden menus and verified that WCDMA, which, I believe is the underlying tech for the local HSPA connection, is preferred to the cell radio.
Looking at the device, if I ask it to check for mobile networks, the list comes back blank. The network status shows "UNKNOWN:0" and the lockscreen shows "NO SERVICE." instead of "NO SIM" (which is what it shows when I remove the SIM). From what I can tell the radio has shut off and will not come back on.
Throughout all this Wifi still works perfectly, so the device isn't useless, however, I'm planning to sell this device and I would like it to be as fully functional as possible when I hand it off to it's next owner, so getting this solved is very important to me. Any and all suggestions are appreciated and I'm basically willing to try anything at this point. I feel as though I've tried everything short of a factory reset, which I'm not sure if that would help (I've even wiped cache and dalvik).
In case it's relevant, I'm in Canada, carrier is Telus.
Thanks for reading.
EDIT: I've just finished restoring the device to Stock 4.0.4 (I've used this stock image before when I had issues with the device and confirmed it is fully functional) and I am still having trouble. this points to either a carrier issue or a hardware issue. I will be calling the carrier in the morning, despite believing that this isn't the case. any suggestions on what could be the problem are still welcome, I'm willing to try just about anything at this point.
@Mystik
Back in the CM 4.1.2 days on the e4gt...we had a similiar problem. Now, I don't have you're device. But when this problem arose in the epic. We had a work around where we would turn airplane mode on and power off the device. Then power the device back up. When that didn't work we had to flash a modem, then flash back to the one we wanted.
Also, make sure after you turn off airplane mode.. that the mobile data under settings/more is enabled... sometimes it will not re-enable itself.
Let me know if this works.. if not I would be happy to help you search up a fix..
Just encountered a little problem today. From the beginning: My Note 3 was rooted/TWRP'd running Vision X 3.0. Gave my wife my new G3 and took the Note 3 back. When I wiped her data in TWRP and restored a backup (same ROM) the 4GLTE icon started flashing on and off. I wiped complete again, installed a new ROM and did the same. Then I Odin'd to the new update. Same issue. I did encounter an issue with switching the phones earlier in the day. I had to get Sprint to do it via chat due to the Note 3 not being deactivated/reactivated correctly when I tried through the site. So I am guessing it could be a bad SIM card or they muffed something during activation. It will at times stop flashing and give me full LTE, but if I reboot or shut the phone off/back on it starts flashing again and the phone gets warm. It will sometimes stop/start if I mess with Connections Optimizer too, either checking or unchecking. Appears to be trying to connect to LTE but something is preventing it from locking on. I would appreciate it if anyone that has run into this before can give me some ideas. I do have a service center in town, and will go in the AM if I cannot find a solution anywhere else. I have never encountered this before.
Also in settings for data, Mobile State flashed between Connected/Disconnected and Mobile Network Type flashes between LTE/Unknown along with the LTE icon in status bar.
Tried killing data and all that. Airplane mode etc.. Sprint service center says it may happen when updating and will calm down in a couple of days..I don't think it was the update since I didn't update until after it started.
Also failed to mention when I switch to CDMA only in Data settings it will stay on 3G and doesn't flash. Has to be an LTE issue. And it is not the towers in the area because the G3 is fine.
Since it's broke anyway, going to Odin NC5 and see what happens. Tried freezing Connections Optimizer and flashing a new Kernel but didn't work either.
EDIT: Nope. That didn't work either. Ugh
Apparently it was a Sprint issue. Had to let it ride for a day or so and now back to normal. LTE is good again. Was an issue on their end when something went wrong during the phone swap.
Had this same problem with my Galaxy Grand Prime and rebooted in safe mode and it stopped. Safe mode disables all 3rd party apps. It is a 3rd party app causing the problem. I had to turn phone off, turn back on and hold volume down button after seeing Samsung logo popup, then wait for the safe mode to appear in lower left corner and release the button. Flashing stopped after that. Turned safe mode off and its still good so far. Hope this helps someone!!
So I have a T-Mobile galaxy note 3 that I switched to a metro pcs Sim card.. The phone is unlocked and has been working fine ever since, until a few days ago. The 4G LTE symbol on the notification bar has completely disappeared. And now I can't access any internet connection or make or take phone calls, message. Etc. I thought it was a Sim card problem but after inserting a new Sim card I get the same disappointing problem. Metro PCS tried changing the ASN network connection to make sure but I hot nothing. However when I shut my phone off several times and turn on the plane mode on and off several times as well the 4g LTE turns back on for a few hours before losing connection again. Can anyone help me with this issue or has anyone incurred similar issues?

When it switches off, what does the status bar symbol look like and what does it say in Settings > About Phone > Status? Have you modded the phone at all? Gotten any recent updates? Changed the modem or rom? Could possibly be the SIM card reader itself. If so, that is an easy, and relatively inexpensive fix.

The status symbol only shows the bar icon that shows it does have a signal but nothing else except time abd battery life. I can't currently check Settings > About Phone > Status since the phone is currently running so it'll show a positive connection. Unfortunately the phone itself is my only current means of using internet (this forum). And how can I check/ fix the sim card reader?
Never modded or messed with either
Hey guys. So I've been trying to figure this out for several weeks with no luck and I was hoping you could help me. I have a Verizon LG G3 on AT&T on 10b. I can connect to 4G LTE and Edge just fine. However, when I try to make a call or receive a call on LTE, the network vanishes instantly. I'm talking from 3-5 bars to no service in within 5 seconds of calling my phone or calling from it. I've tried flashing different modems and the problem still persists. I already tried flashing the stock (what I'm on now), factory resetting, clearing the cache, etc. and have not been able to fix it. Today I called AT&T tech support and after they re-registered my phone I was able to make one phone call before the problem reappeared. When I made the call, my LTE dropped but I stayed connected through 2G/3G/Edge not sure which one.
The only other time I've had it working properly is when I had Cyanogenmod installed. However, that led to another issue. With Cyanogenmod, my phone would crash within a few minutes of booting. Most of the time I couldn't even make it through the setup. To be more specific about the crash, my screen would freeze and become unresponsive for a dew seconds and would then turn off completely. The green LED would turn on and stay on. Every time this happened I would have to pull my battery. The only way to prevent the freezing was to turn on airplane mode. If I turned off data or had the phone SIM-less it would still freeze airplane mode was the only solution.
If anyone can help me with either of these issues I would be greatly appreciative. If you need any more information or want me to post logs just let me know and I'll happily do so.
Here's a quick recap incase you don't want to read through the walls of text.
VS985 10b on AT&T
EDGE works fine
On 4G LTE network disconnects when making or recieving call
Cyanogenmod fixes network issues but freezes when not in airplane mode

I think you are talking about making calls on Voice over LTE. I am not surprised Verizon rom does not quite support it. Maybe you can try this swap boot.img hack to install AT&T rom and see if it solves your problem?

Thanks for replying. That's my main theory too. However, according to my research, the VS985 didn't get VoLTE until the 12b update. I'll definitely try an AT&T ROM when I get the chance at the very least I'll probably learn something from it. Any chance there's an option to make LTE data only on this phone?
