I have the LG-VK810 from Verizon. It worked fine last night while playing PoGo. Plugged it into the charger before bed. Woke up this morning and everything works except for my 4G radio. I have 0 signal. No bars.
I have factory reset the tablet, pulled and put the sim card back in, checked my mobile network settings.. nothing is bringing my signal back, has my radio just burnt out?
If so, I have a spare VK810 that doesn't work, would it be possible to simply swap the radios?
Thanks in advance.
Have you checked in other areas to see if data is working? Checked in Settings / About to make sure it still has an IMEI?
Are you running completely stock (non-rooted) 36B?
Try a SIM from another device?

My gf text me this morning saying that she can't get service unless she selects 2G only. She was having issues with her phone and thought maybe the SIM was the problem since it was several years old. She went in and got a new one last night and things seemed to be OK. When she woke up this morning, she again had no service at all ('only 2G' unselected). She switched back to 2G only and is getting service. Even with "only 2G" unchecked, it should still bounce to Edge if there's no 3G signal, right?
I flashed CM7 RC1 or 2 for her back in January and I believe she has the latest radio update.
Any advice? Is this a hardware/software/SIM or network issue?
Any help is greatly appreciated.
If you can, you could try making a backup and flashing another rom?
I'm thinking the very worst problem could be a busted antenna. D;
... But we'll try everything we can before we come to that.
So I've had this phone for over two week now, and I rooted it and flashed it with FrostyJB v5. Everything was running well (excluding the battery life, which was better in v4 but that's a different topic). I was at my school connected to their wifi earlier tonight and when I left school, I can't make any phone calls (i have a circle with a slash through it where my signal bar would normally be). I think it has something to do with my APN or network or something? I'm honestly new to this. I would appreciate it if some one could help me solve this problem. The phone is a T-Mobile phone, which I bought from a T-Mobile dealership. The SIM was working properly until tonight. I tried removing the SIM and rebooting, putting the SIM back in, rebooting. etc.
TLDR: My 4G doesn't work, I'm not connected to any APN, my phone is rooted and flashed with FrostyJB v5 but I bought it from a T-mobile dealership with a T-mobile sim card. Help. Please.
I can provide addtional information if needed
Is your imei still there? Check it in settings/about phone. And are you sure airplane mode is not checked? Were you doing anything developement wise when it went out?

my imei is still there. it is not in airplane mode. I can't connect to my 4G or my T-Mobile network. I was not doing any development when it suddenly turned off. I was walking out of my school around 11:00pm CST (if it helps, I get no reception at my school's building). I turned my wifi off and turned my 4G on via drop down menu and it wouldnt connect. I tried rebooting my phone several times, using HOT BOOT and REBOOT.
Can an mod/admin close this thread out? I solved the issue. You need to turn off wifi calling for it to work. dur. sorry
Hi guys, I need some serious help. I had the original Note and upgraded to the Note 2. My wife got my original Note. The Note 2 is not rooted. I had my new Note 2 for about 4 days, when I notice that my 4G/LTE (I am in Denver) "switches off" and then I don't have a data connection (can't connect to internet etc.), but I still show full towers on the phone and I can make phone calls. When I restart the phone, the connection is restored and I have 4G/LTE. I can also restore my 4G/LTE by switching my phone back and forth between airplane mode.
At times I would be hours without a data connection and then suddenly the connection restores itself (without me restarting the phone). I have compared my connection to my wife's original Note and her phone has constant 4G/LTE, even when I have no connection on my new phone. It is not area specific since I might have no data connection in the morning, but in the afternoon everything is fine (that is now if I don't restart the phone and just leave it be). I took the phone back to Best Buy and exchanged it for a new one and I have the same problem with this phone.
It is driving me crazy since I need my data connection. I've been on the phone with ATT and we've reset the phone and did all that. No luck. They are checking into "other solutions" but I am not hopeful. My questions:
1) What can I do. Anybody else with this problem and how did you fix it.
2) Is this a phone problem or tower / ATT problem (I don't think tower since my wife's Note is working fine)
3) Should I wait for ATT or try and exchange this again for a third time? My 30 days are running out.
Any input will be much appreciated.
Thanks

While it's possible you've received two faulty phones, the more likely culprit is the only thing that hasn't been changed out. The SIM card.

Good idea, I will get the SIM card changed out. Thank you for your input.
My original battery was draining fast and wasnt fully charged so before work I threw in an anker battery I've had for about a year. Phone booted fine until I went to make a call and there was no network connection.
Since then I've put the original battery back in, restored my last backup before cyanogen 10.2.1 rc , and then flashed 10.2.1 stable. I reflashed my modem and then flashed the newest modem.
No luck. WiFi still works. Did I somehow fry the radio with the battery change? Not sure what could have happened
Also imei still 14 digit
So I tried the sim in an old phone I had. Still no network. I took it to a local store and had them change the sim still nothing on either phone. They popped the sim into one of the phones they had there and the network connected. The only difference between my phones and theirs is mine are rooted and running cyanogen. I'm confused. I also flashed stock firmware 4.3. Still nothing, though wifi calling and texting does work so I think the sim is ok.
I had this phone for a while, put it in storage (my desk) and then gave it to a family member. After putting sim card and flashing latest slimrom 4.4.4 SGH-M919 (baseband m919uvuamdl)
wiped phone etc... restored msgs and few things.
Everything seemed fine, after phone goes to sleep for a min or two, it shows then no service!
So I tried all apn settings etc... switching from 4g to 3g, then did 2g and boom it stays connected on 2g without issue.
So went and got a new sim card, apparently this was very old 2g sim card that I cut to fit into adaptor.
Does anyone know what is the issue? the new sim is having exact same issue and only works on 2g, if putting it to 3g or 4g, it works for a while, but after it goes to sleep and you wake it it shows no service.
Also this kills the battery as the phone seems to be trying to connect?
Should I flash the rom again? do I need different baseband? flash to older version of rom?

Try a different rom....if that doesnt work...then flash the stock firmware with odin (twice to make sure it sticks) and see if its fixed.
I went and did one of full firmware over Odin

you know whats crazy? it worked but it kept the old apps and accounts? Half the stuff didnt work, so I went and did a factory reset, that wiped everything and now the phone seems to be back to stock and working properly.
crazy, never thought that a ROM update could mess things up for the radio?
