I can't seem to find a fix to my problem. After my first flash on this phone (cm 10.1), I lost all mobile data. All i get is a blank triangle icon or sometimes a roaming icon. Wifi works fine but i can't go about my day if i don't have my data! I tried reflashing a few times and a few different roms/builds, and it still never connect. I've tried rebooting without the sim, and putting it back in etc, no luck
Does anyone have a fix or suggestions on how i can fix this?? i've been at it for a few hours already and i'm starting to stress out.

Your default APN settings may be the culprit. Are you on Verizon?

pull down notification bar swipe the bottom and then click the settings button, go to more > mobile networks > CDMA Subscription type > SIM try that and see if that fixes it, if its set to NV it wont work so switch it

I don't know what that is! Sorry, I'm new to the dna.
I just realised i can't make/receive phone calls & text messages.
Also every time I switch from NV to RUIM/SIM it switches back to NV

When mine is doing that I also change system select from Home only to Automatic. I let it sit for 5 minutes or so, then reboot. If it switches back I reselect, reboot. Try again. But most of the time once or twice is all it takes. It's a pain but normally will stick.
Also have you tried going into recovery and wiping the cache's? I think I've had to do that a couple of times. Honestly don't know if it makes a difference or not, but I figure it can't hurt.
Edit: Also you can try switching from NV to RUIM/SIM back and forth a couple times. As I said before just guessing but these are just a couple things I tried, and seemed to help.
Sometimes I'll flash a ROM no switching to NV on me, and other times it will, even with the same ROM. I think my phone has a mind of it's own.
There was a service code you can type in to change your network settings.
It was something like *#*#344XX#*#*
I cannot remeber exactly what it was but I need it also.

Go mine to get 3g working by flashing cm10.1.
Then going into settings mobile network.
Then setting network mode to LTE / CDMA.
Then setting CDMA sub to RUIM/SIM.
But after reboot it resets back to roming.
Also If i go to about I have no phone number.

Since I can not yet make a post in the Dev section, I'll have to do it here:
I recently flashed the latest MIUI ROM on my phone (2.6.1). I made sure to grab the CDMA version, as I have the X912 on Verizon. In my area, I always get 4G signal, as well as decent cell coverage. After flashing the MIUI, I only get 3G, and it tells me I have no service. No one else seems to be reporting these issues, so is it just a GUI error, or something more? Any help would be greatly appreciated.
How can you have 3G and no service at the same time?

You should had asked in miui thread in dev section. what u cannot do is to start a thread there.
Well
Install an app from google play called phone info
Run the app and choose wcdma and wait for a signal. Depending the miui you are you'll see 3G icon even if on 4G/Lte. If you dont get a signal in first time choose another band like gsm auto wait a little (~10s) and press wcdma again.

Scroll down to "Set preferred network type"
Hit the little arrow on the right next to "CDMA auto (PRL)"
Select "GSM Only"
The screen will refresh and scroll back to the top.
Scroll back down and hit the arrow again

Ok, thanks a lot. I actually flashed back from a backup I had in the meanwhile, so I'll put it on again and see if I can get it to work. It was very odd, I had data access, but couldn't place a call, and it told me there was no service. I did mess with some of those settings though, so maybe that's part of my issue
I have AT&T Note, stock ICS, rooted. I have been having problem with inconsistent data connection, even though I have good AT&T signal. For example:
1). Signal is 4-5 bars
2). I CAN make phone call
3). Open browser, Gmail, etc - the "4G" icon shows it's trying to connect, but nothing happened. All the application will timed out.
I tried this in different locations (home, work, airport, etc.) and same problem.
I didn't change the APN or install custom ROM. I am trying to figure out if this is just my phone (bad radio, etc.) or a widespread, known problem for AT&T stock ICS.
Please chime in if you have the same problem.
Did you try powering down.... Then a battery pull..... Battery back in.... Reboot..... Turn off wifi... Make sure data is turned on..
Write back.... Good luck

I did try those, specifically:
1). Power down and battery pull out
2). Airplane Mode
3). Disable WiFi and BT - leave only cellular signal
The only thing I have not done is hard reset.. But before doing that (it'll take me a long time to re-configure everything), I want to get feedbacks from other first..
BTW, the ONLY thing I can think off that MAY mess up with the connection is Avast! Anti-Virus. It has a built-in firewall (root required) to prevent select apps from accessing the Internet. However, with WiFi, I have no data connection issue even with Avast! firewall running.
Un install avast and see if that helps.

I did, same thing... Can make voice call but no data. Even when I rebooted and pulled the battery. About 10 minutes later.. data magically comes back!
Does anyone else have this problem? If yes, please chime in..
I am thinking of doing hard reset. Will this make my Note lose root?

I can't reset the default APN...check I can't even edit it. I think AT&T blocked it.
Did you just get the note or did this just start happening? If you just got the phone did you buy it new or used?

you are right.. you cannot edit and change the default ATT APN....
BUT!!!
You can create a new one.... and choose the new one over the default...
you are allowed more than one APN...
Modem .....and APN settings are the most likely causes.
APN settings first of course.....g
Thanks for the suggestions.
The original APN cannot be edited, so I created a new APN and select that. When I press the "back" button and go back to the list of APN, the phone AUTOMATICALLY selected the original APN, not mine.
I selected that again, press back button and waited for 5 minutes (in case the phone trying to update whatever it needs with the new APN). Went back to the list of APN and the original APN was selected again! (???).
So I think something went awry with my phone (I already uninstalled pretty much everything), and just for a test, installed a new ROM (Padawan v7). So far so good, but I haven't done extensive testing (at home, not traveling) yet.

So, over the past couple of weeks, my phone just randomly loses the ability to use data. I use that term because, 4G is still on the phone, i'm not getting a no service signal, I just can't do anything that would use data. I'll be at work, using the Wi-Fi, then i'll leave and all of the sudden, nothing. It's like my phone just loses signal, but doesn't tell me it is. The little arrows under the 4G symbol don't do blink, nothing happens. I end up having to restart my phone. I haven't done anything different for this to happen. No updates, i'm not in abnormal areas when it happens(even if I was, it comes back after restart), nothing. Anyone have any insight on this?
I've had the same issue for about a month now. I am rooted and used this method
http://forum.xda-developers.com/gal...-to-update-to-i545oc1-5-0-1-keeproot-t3096558
if i reboot i get my signal back, or sometimes if i toggle airplane mode on/off it will come back. haven't been able to find any fixes on it yet though...
I have the same issue, I've found toggling airplane mode works 90% of the time.
Sent from my SCH-I545 using XDA Free mobile app
If u go to > Settings>Wi-Fi and tap the hardware menu button (bottom left most button), tap advanced...see if Smart Network Switch is "checked". If so, try toggling.
This is the worst bug yet!
I hope someone finds a fix to this soon. I am running 5.0.1 on a Verizon S4. All the techs at the Verizon store could tell me is that I need to upgrade to a new phone. After telling them I didn't want a new phone right now they gave me a new SIM card but that hasn't helped either. When I go into an area where I don't get service it seems like my phone just stops searching (perhaps to save battery?) Then it never seems to wake up and find service again even after I go back to a known 4G location. The toggle airplane mode on and off thing rarely ever works, so I don't think the radio is just "sleeping" to save battery. A complete restart is the only thing that helps.

I have this same issue (stanglite 5.01 ROM) and have tried a number of things to resolve it. I can post those steps if it is helpful to the discussion. In short, I've tried several modems and resets.
I should specify that mine is not identical to the OP as mine specifically shows that I have no signal. and it doesn't seem to be trying to find signal.

Not sure if it's just me or not, but ever since the update, my antenna seems weaker. I've never gotten much service at my house, but typically, I could go near a window, or outside and get service. Now, once it goes so long without service, the only way to get it back is to restart my phone. I've tested this even going into areas where I know there's good service. I've tried toggling airplane mode on and off, and even that doesn't get it to hook back up. It's incredibly annoying having a phone I pay this much for, and yet, can't use it without restarting every time I want to make a call or text.

One of the responses from this or another thread on this subject mentions to try changing "Preferred Network Mode" to LTE/CDMA. I did this and then rebooted (didn't work until after the reboot). It seems to have corrected my issue (I did also uninstall some apps I don't rely on but otherwise no other changes). Note that after another reboot the mode seems to have switched back to Global, but the issue has not returned.
Change "Preferred Network Mode" from Settings > More networks > Mobile Networks > Network mode.

There are tons of hits on this issue but no solutions...
It would be nice to find the actual problem instead of throwing a bunch of things at it to see what sticks.
I have been experiencing 4g connectivity issue the past 3 weeks. I have been running cm 13 rom for about a month or two with no issues. But then 4g connection disappeared and i was only getting 3g. After trying different fixes, i have narrowed down the the problem to prl issue. When phone restarts or battery is swapped, i get notification that sim card is not detected and only 3g data connection. Once i do a prl update no sim notification goes away and 4g works. Once phone restarts no sim message is back and 4g is gone. Any idea what the issue could be and how to fix it. Thanks.

I dont have the rom so i cant give u an absolute answer here but I would try toggling off the battery saver because if its on and active it can unfortunately switch to a lower band to conserve battery so that would be my first guess. Switch it off and reboot.
---------- Post added at 12:13 PM ---------- Previous post was at 11:43 AM ----------
If that doesnt work try another method. Download shorcut master lite. On the top left click the 3 dots and select search. Type in Modem. Now look for the one on the list named com.lge.hiddenmenu.lte_only.modemsettings make sure u choose the right one they all look similar but that one says LTE_Only thats the one u want. now click it. Then press favorite so its there when u need it. Then launch it. Select modem settings, then select RAT selection click that. Here you will have a list like LTE Only, GSM Only, WCDMA Only, GSM/WCDMA etc.. But at the top you have Auto. Thats the one i picked Im pretty sure thatll connect u to 4G thats what worked for me
I have just encountered a problem after performing the dial in this thread from XDA:
https://forum.xda-developers.com/lg-v30/help/us998-hidden-menu-lg-v30-v30-t3719219/page1
Just curious to find out all the band numbers my phone supports. But, After selecting one band it could not automatically switch to another.
And it has made the situation worse when i tried to do a factory reset from the SVC menu. Now i do not have the 4G network at all. No access to internet. Factory reset from the phone settings also failed to fix the problem.
Is there anything i can do do make my phone work normally again? Do i need to flash the KDZ file to restore to my default network settings? But i seem to be unavailable Now.
What can i do, guys, please help.
I did the steps in that thread this morning and the same thing happened to me. I was able to factory reset and the issue was fixed upon first boot.
You might try resetting again to see if it'll fix it.

I have tried several times and it did not work. thanks anyway.
contacted LG service, and they are talking nonsene:
quote:
"1 - Check your current settings. This is important to retain 3G data when moving out of 4G range. You can find this under Settings > Tethering & Networks > Mobile Network > Network Mode
2 - a menu will open automatically. Click on Phone Info and scroll down to where it says Pick Prefered Network Type.
3 - Press the drop down box and select the option that adds LTE along with your old options. (pick LTE/GSM/WCDMA to turn on 4G)
4 - your network will reconnect and you should now see a 4G icon appear in the top bar.
With android 5.0 you will find that 4G now appears correctly in the "preferred network mode" under Settings > Tethering & Networks > Mobile Network > Network Mode.
If by any chance that this did not work, then try this:
First go to the app *easy battery saver* then instead of super mode, Go back to *normal mode *. It will kick you back to your normal settings. If by any chance it doesn't work try this:
This method however is to fix and reset 4g in general, so it should work;
First of all download an app called "any cut" free from market. Then after it downloads and installs, go home screen and create a shortcut >then select > activities > and then select the "any cut" app. After that it'll send you to the app and from there you have to press on "activities" option and Scroll down until you see "LTE configuration" (its mostly the first one that starts with LTE). Then as you select that it will have created a shortcut action on the home screen. You then go to home screen and look for the shortcut you have created, it'll be called *lte configuration*. Open it and then press on setting initialization. Now, it will reset your lte settings and the phone will reboot. After that you should be able to be running 4g nice and clean.
If in case these didn't fix the issue, please contact your carrier. Typically frequencies and bands problems are network related. "

Your last option would be a restore through lg bridge. Its just going to reset everything back to normal. I accidentally did the same thing on my h932 and had to reset it. In my case LG bridge flashed the same software version but since the us998 is getting the 10c update it will update you to that version.
