[Q] No 4G all of a sudden? - Verizon LG G3

I have a VS985, rooted, on a custom ROM currently. The other day, I noticed I was only in 3G on my phone in an area where I usually get full 4G signal (tower is about half a mile from my apartment complex). It has refused to switch back to 4G ever since.
Here's what I've done so far:
Reflashed current ROM
Flashed new ROM
Flashed modem
Airplane Mode On/Off
Switched Networks to GSM Only, LTE/CDMA, and Global
Tried turning data on and off
Pulled SIM card out while phone was off
Access Points reset to default
Any other options? Should I KDZ back to 12B and start from scratch?

Sounds to me like you may have fried the 4g in the sim card, happens occasionally. Vzw should give you a new one no problem.

Turns out the 4G would not work even with a new SIM. Replaced under warranty.

3g lose connection while downloading.

Ever since Verizon network went down a few days ago I can't get a solid connection whenever I download anything. Browser seems to load fine. I try downloading several apps from the market but cannot complete the download due to lost connectioime. It will just stop at any time during The download. Same with files. I dont think is the rom. I'm on cm7 pre-release. Flash back to Tesla but still have the issue. Is anyone else have this issue?
Are you close to a 4G area? Try locking your radio to 3G and see if it improves.

No I don't get 4g in my area. How do I lock 3g? I have it set on cdma / edvo auto.

You go into the phone dialer and input *#*#4636#*#*, choose phone information. LTE mode for only 4G, CDMA auto (PRL) for only 3G. You can change it back to normal by using CDMA + LTE/EvDo auto.
I've been having the same exact problem.

Just installed the latest radio and is still having the same issue. I hope is the network then since you're having the same problem too.
I have das bamf remix 1.5 on my phone and I've been having very slow downloads lately when it says I have a full signal.... Tried both modes as mentioned above and problem persists. Can't even load a whole you tube vid. WTF
New radio problems
I had similair issues, and I went back to stock 605.6 radio and a simple debloat rom and it fixed my issues, I am also set to CDMA(PRL) as I'm in a 3G only area
on the new radio my 3G connection was unstable and my GPS wouldn't lock
all of this only occurred after the verizon network went down and came back up.
before that I was having my problem with the new radio. I'm waiting on 605.6 until Verizon officially updates the radio, because I think they changed something that is currently only working with the old radio, the only one they have to support at this time, just my conjecture of course, but I've tried it a few times going between an old radio/old rom and new radio/new rom and it's consistant
Having the same issues. Tried all the radios, but downloading from the market place still goes at a snails place. Like everyone else this started after the lte network went down and came back up.
Update:
Found this on Android Central: Created Cheeta186

Alright, I just got off the phone with them and they fixed my problem in less then 5 minutes. The problem was caused when the network went down, and when it came back up, some of the thunderbolts would not connect correctly causing the connection issues. When I called customer service the woman brought a tech guy on the phone and he had me take the battery out of the phone WHILE IT WAS POWERED UP and then take the SIM card out and he did some kind of "network reset" to my SIM card and now all the issues are gone. Worth giving them a call and seeing if this fixes your problem. IMO VZW has the best customer service hands down, they are always so helpful and will make conversation with you during the luls while on the phone (IE when your phone is booting up).

Can't check this myself yet, because verizon customer service isn't open as of now.
Interesting. I'll give Verizon a call. Thanks.

Strong 4G but weak LTE signal

Does anyone else experience this or know how to fix it?
I get weak LTE most of the time (2 bars)but when i do HSPA only for 4G, it gives me full bars. I also get network/modem freezing where i have to restart the data connection to get signal back.
Running stock gb and stock kernal, rooted with dag kernal and running cwm base recovery.
Sent from my SGH-I717D using XDA
Yeah, I see the same thing. Manually turning data on/off seems to work for me.
-Edit-
What I mean, is that manually turning data on/off seems to reset to LTE. It's not an acceptable fix, I know, but it gets the job done for now.
yeah same here i'm on rogers and when i enable LTE i get 2 bars and as soon as i put gsm/hspa auto mode boom 5 bars. i called rogers and they told me to factory reset my phone, i did helped but a couple of weeks later same problem. i don't want to have to factory rest my phone every couple of weeks... they also told me if the problem persists to send it to repair. it's a brand new phone! and it seems like i'm not the only one witht his problem so. anyway the ics update should come out this month and hopefully it will get rid of this problem.

Lost 4G on CM9

Important info: Running CM9 (len00bs)
So last night I had an AT&T sim card that i wanted to try out in the rezound. Powered down, popped out the vzw card, popped in the AT&T card. Couldn't get signal to show up, so i powered down and popped the vzw card again and got signal. I'm stuck on 3G and it won't go to 4G. I checked to make sure the settings were on LTE/CDMA, and I tried toggling LTE Only and it goes to no signal with a roaming logo. I tried toggling data on and off, and it still kicks on to 3G only. It was working perfectly prior to popping in that AT&T sim. Tried restoring my original backup through TWRP, but it won't go passed the 4G boot logo (assuming i need to flash the old boot.img back on for it to boot properly?). So then i restored the CM9 backup i had and i'm back to the 3G only issue.
Is there something else I need to do to get it to see this is a 4G card?
Found the problem. Even though LTE was selected in the front end on CM9, I went into *#*#4636#*#* and it showed GSM was selected. Looks like popping in that ATT sim flipped this to GSM/CDMA auto (PRL), thus limiting me to 3G. I changed it to LTE/CDMA auto (PRL) and bam 4G is back. :good:

[Q] APN - LTE - 3G - won't stick

Hey folks, any ideas why my APN will auto-switch to non LTE - Verizon Internet every fourth or fifth time I unlock the screen? It's been doing this for about two weeks since I flashed CM10.1 and Devil Kernel. I've since tried going back to TW as well as wiping everything on the phone including system prior to flashing different ROMs. Right now I'm running CM10.1 08-13 nightly with Plasma 1.67 kernel and it's doing the same thing.
At first I thought it could be signal strength causing it to not connect to LTE, but it's completely switching APN to non-LTE. At wit's end right now because no combination of stock TW or CM10.1 will let it stick.
Guess I should ask my question:
Is there a way to make the APN stick to LTE - Verizon Internet instead of letting it arbitrarily switch to EHRPD - Verizon Internet, which drops my LTE connection? Anyone have any ideas as to why it's switching on its own in the first place? When I'm on the EHRPD - Verizon Internet the phone doesn't seem to ever switch back to LTE, even though what I read on the 'net says it should be switching back and forth depending on signal. I have to go into the *#*#4636#*#* menu and switch it back to LTE/GSM/CDMA auto (PRL) as it has switched to CDMA auto (PRL) when on EHRPD - Verizon Internet.

I am having the same issue, but if I force it into LTE through the test menu I can get data at 4g speed. But it shows no signal.
I thnk it is suppose to be on the VZWINTERNET. I just had this issue with carbon, and I figured out the network options I were using was wrong. I kept choosing LTE/CDMA, but it should've been LTE/CDMA/EvoD and once I did that i got snapepd back into 4g.

On the advanced data menu that is what mine is showing, when ever I select the LTE apn it bounces back to a 3g one.

When you flashed the ROM originally and started having this problem were you asked to activate your phone. I am having the same issue after flashing a 4.3 ecliptic one ROM on my HTC One. I was running the same ROM but 4.2.2 before flashing. The first thing I was required to do was *228 for activation. I used option 2 to update the roaming capabilities and after that I could no longer stay on LTE. I was pushed over to ehrpd. Even when I tried LTE only using the method listed above I could not get a connection to the internet (even though it showed APN= LTE).
I will probably just go to VZW and get another SIM card for LTE.
Any thoughts would appreciated.

You will need a new sim. You don't have to activate and especially not update via *228 with a 4G sim card.

LG V10 4G LTE connection problem

Hi,
I have been experiencing a few issues with the 4G LTE on my LG V10 H901 (T-Mobile). What happens is this.
In Network mode I selected GSM / WCDMA / LTE Auto. This initially worked fine and could get a data connection. 2 days after, I noticed I couldn't get a data connection anymore, the 4G LTE icon at the top was displaying with a down arrow lit. So I went in the Network mode and checked my APN everything was ok. Decided to switch from GSM / WCDMA Auto where I got a 4G connection (icon 4G displayed at the top) and I finally got a data connection.. Changed it back to GSM / WCDMA / LTE Auto, and there I was back on LTE... I had to reboot my phone and that is when I noticed the same thing happened again!!! No LTE connection and had to first select GSM / WCDMA Auto to get 4G.. If I reboot with GSM / WCDMA Auto I get a data connection fine.. The problem only occurs when I have the Network mode on GSM / WCDMA / LTE Auto. Anyone else having this issue? Is there a fix?
Thanks
I would say it's a hardware problem with the phone I've had mine for a month i never touched network settings and the phone gets a better data connection then any phone I've ever had LTE pretty much all the time where other phones wouldn't maybe a factory reset would fix it worth a shot
The first V10 i got from T-Mobile had somewhat of a similar problem but with WiFi, it would connect but speed was horrible. And LTE isnt that great in my area either. I read around the forums and notice that many have done factory resets and that fixes everything. I did that and lowe and behold, it did. WiFi was fast again and LTE speed improved but still sucks....its my area, not the phones fault. For some reason, a reset helps.
However, I was still just 4 days in since I got my phone so I just went back and had them replace it. I just told them that the WiFi doesnt hold....they didnt really ask me tons of questions. I replaced it only because I am paying for the phone and me having to do a "fix" to make it work doesnt sound right...so I want a new good phone lol. The new phone worked fast from the get go...no reset needed.
Just got the V10 was having those wifi issues initially so brought phne back n exchanged for another 1 and this 1 workes fine but now Im having dropped call s inside my house ,verizon said no antenna issues i can bring phne back n replace for something else or another v10 but that is time consuming ,please anyone having drop d call s....I live Long Island NY so verizon overage is better then most carriers...INaNYmin...
I began having the exact same issue on Jan 16. Had the phone since Dec 25th, worked perfect. Then, all of a sudden, it began to lose LTE connectivity. At first I thought it was a down tower, but the problems persisted an eventually got much worse wherever I went. On a full charge the phone will behave normally for a while, but eventually it starts losing data connectivity altogether, cycling between 4G LTE, 4G, 3G, 2G, trying to connect. during this process the battery drains a lot, it never really connects, and sometimes calls and text messaging fail. Tried every network setting, soft reboot, hard reboot, safe mode, clear cache, factory reset....problem persists. T-mobile concludes it must be defective. We shall see. Awaiting a replacement.
Having the same issue. Looks like it's a common problem. Any fix for this yet?
I have a similar issue.
it always seems to find the LTE signal, however I have no data and the battery drains very quickly.
If I have it on GSM/WCDMA/LTE, it seems to have connection issues. However, the data will connect on GSM/WCDMA. Once I have data, then if I select GSM/WCDMA/LTE, and it will connect to LTE
It is a Tmobile version. I am using it on Bell (Canada)... however it works fine with Wind & Tmobile, with no issues.
I am hoping that this will be fixed with the Marshmallow upgrade.

Wind works on hspa not LTE. That's why it works. I've noticed that it works fine on hspa(4g) but when I put it on LTE(4gLTE) it works for a while then stops.

For me, Wind works fine on GSM/WCDMA or GSM/WCDMA/LTE
With Bell, it will not connect on GSM/WCDMA/LTE.
However, with Bell, if I put it on GSM/WCDMA, it will connect. Then if I change it to GSM/WCDMA/LTE, it will connect to Bell's LTE.
Occasionally, it will lose its data connection... and then if I toggle between GSM/WCDMA & back to GSM/WCDMA/LTE, it reconnects. This seems to happen once every 2-3 days
I don't know why it does this. It was actually very frustrating until I figured that out. I almost dropped Bell because I was not able to connect on LTE for the longest time!!
I just keep my Wind plan for the US roaming (on Tmobile LTE down there)

Yup exact same issue with me and that's how I resolve it as well I'm with koodo and I lose LTE. I was going to warranty this phone but I think it's a common issue.
I just want to quickly point out that I am seeing the exact same issue on Virgin Mobile (Bell). I also noticed that the performance of the phone decreases drastically when it is connected through mobile data instead of WiFi. Anyone else sees this and knows how to fix it?
Lg v10 t mobile no connection
I'm having a similar issue I get a 4G LTE signal but if I make a call once I end it I loose all signal including the bars it wont let me text or call it says network not available and it will do that till I travel a few miles. I'm not in a dead zone because it does it in the heart of the city and on the buisest streets in Tampa Florida then it will come back and sometimes I won't get a signal for a entire day out shoe have any solutions?

Hey,
I'm using this phone in Canada too, on Telus. Ever since the OTA update 2 days ago I've been having data connection errors over the network. Did you find a fix?

I'm seeing this too, but it just started after my OTA update. So frustrating bc I love the phone.
I had a similar problem. With The latest software (,,v20c,,) With the LGUP Software I software put it back (,,v20a,,) . And it seems the problem disappeared. Last part of the modem software is not good. Even test elements. Sorry for my bad english for knowledge. LGUP software very simply . ( i have V10 960A Unlocked (Eu version) android 6.0 and T-mobile LTE )
