New Phone won't connect to 4g after root. - Verizon Samsung Galaxy S 4

I had a HTC DNA for about 2 years and was rooted and had tethering.
When I would put the phone on global mode it would drop the 4g/lte and I could only get 3g after tethering wifi. If i did not use tethering for a while I could go back to global mode and it would keep 4g. But the next time I would use tethering it would kick me back to 3g the next day and I would have to go back to the CDMA LTE mode.
I just bought a Galaxy s4 and used it for about a week before rooting it. After Rooting it I can no longer get it to connect to 4g. I have gone into the data settings and told it to only connect to CDMA LTE.
What can I do to correct this issue?
Has Anyone else had this issue?
Can verizon see that I am rooted and using wifi tethering?
Can I force my phone to only connect to 4g and ignore 3g signals?
I am running I545VRUFNK1
kernel version 3.4.0

Try editing apn settings to lte. Perhaps you can no-wipe odin if you are just rooted, so you can keep your data.

I had an issue that my phone wouldn't connect to 3G even if the icon showed that it was available. I tried everything. The only thing I could do was airplane mode and then back. If 4G was available it would kick in. If not, no data for me. I did a no wipe odin and that did my phone in. It would boot but then got into a loop which made the phone useless. I was forced to a full reset.
But that fixed my problem. I rooted and was fine. Running NC5

[Q] INSTALLED CM7 RC0.4 Lost 1x 3g but have 4g

Anyone help me out on this. Ive been running cm7 smooth as butter for the past 3 weeks. Everythings great. Slayer Released .04 on twitter yesterday. I installed and lost all data no matter what I did. Went back to my original backup from the day i got the phone which is also the day I rooted. Still same thing. Only 4g. Now I am no dummy I tried everything. I went into ##778, modem settings set the rev a to enable. I commited the changes and and rebooted. Im at my parents who have 4g but where I live its 3g so i need it to work. Anyway. After doing that I could toggle between cdma and lte/cdma auto and could get 3g and 1x and 4g. So as most instructions tell you as does verizon wirelss once I got all 3 working I went back to ##778 and switched back to ehrd or whatever it is and commited and rebooted. Same thing I can only get 4g again. Verizon said there are no problems with there networks where i am currently located. I've been working with android for over a year and am not a dev but am in training. No matter what I do I cant get it to stick when I go ehrpd. I did get it to stick once and tried to go back to cm7 and couldnt get any data this time. RC.03 beings rc.04 did this. now I can only get data on sense roms and I have to keep rev a to enable and if I leave a 3g zone to 4g I have to manually change over and vice versa. any help would be appreciated
I think there are only two settings that you should use. CDMA auto (PRL) for 3G and CDMA + LTE/EvDo auto for 3G/4G. The CDMA + LTE/EvDo will switch as needed.
No it doesn't switch. The LTE cdma auto won't switch

You must set to CDMA / EvDo auto then wait few seconds once you get on the 3g network then set to CDMA + LTE/EvDo Auto. It does work for me switch to 4g and it took awhile to get on the 4g network.

[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.

[Q] Problem with LTE/EHRPD

Hi folks,
I have a weird situation with my phone.
Under stock, the only way I could get a data connection is if I ran it in CDMA mode. If I turned on LTE/CDMA mode it would automatically show as "disconnected."
If I used signal check pro, it would say I am receiving eHRPD signal, but unregistered.
I can connect fine via EV-DO. Have a stable connection.
Under Cyanogemod, LTE is turned on, but automatically falls back to EV-DO.
I did talk with Ting and everything seems to be normal.
Any ideas?
Im curious about this too
I'm curious about this too, because I have the opposite problem where I only connect over CDMA/LTE
(stock 4.3 rooted, S-off)

Same here. Can't use CDMA only mode as it immediately disconnects. Also having issues with LTE dropping out constantly and I can only get it back with airplane toggle. Weird thing is that it never drops if the phone is plugged in. I've tested this extensively too.

That's really odd...
My wife has the same phone and everything appears to be working fine for her.
Well, I tried going to LTE/CDMA mode last night and it looks like everything works as expected now...
Really weird.
I know Sprint has been aggressively upgrading towers in the area.
Maybe just a glitch in the matrix?
I am running stock and have been having this problem for awhile now. Phone works fine in CDMA only mode (EV-DO) or if LTE connects. But the phone absolutely will not function over eHRPD, giving the error "Unable to establish a wireless data connection. LTE:ESM-65535". I had this problem three months ago for about a week, then it went away. Came back two weeks ago for about a week. And now it just started happening again. I always contacted the various support channels, although I never really heard back from anyone, so I don't know if someone got my message and fixed it or if it just went away on its own.
When it is fixed, my phone doesn't attempt to connect to eHRPD, so that when LTE drops out or is unavailable, my One Max drops to EV-DO and works great. But, after the over-the-air update from HTC two days ago and a forced profile update, my phone once again tries to connect via eHRPD, which clearly does not function.
Okay, I have finally fixed it myself. I used SignalCheck Pro to enter the Data/EPST menu in edit mode, typed in my MSL, went to Advanced, selected eHRPD and set it to Disabled. Now the phone seems to work just fine again. Still no idea what is going on here, or why I didn't think to fix it this way before, but here we are.

[Q] DNS_PROBE_FINISHED_NO_INTERNET galaxy S4

I have a rooted S4 schI545 Build kkot49h.i545vrufnk1 android 4.4.2
I blocked the OTA few weeks ago and everything seemed fine.
Just recently I have been having issues connecting to internet via my data plan. Ihave unlimited Data and have rooted my phone to tether. Recently I have only been able to get 3g coverage at best and most of the time I have issues connecting to the internet.
I get an error in chrome. DNS_PROBE_FINISHED_NO_INTERNET I have to cycle the phone or cycle the wifi or airplane mode to get 3g back. My wifes phone get 4g just fine and she is not rooted.
When I am not getting internet and the 3g symbol is showing it will show packets going to Verizon with the little out arrow flashing but nothing coming back. Once I cycle the phone I will get arrows showing packets coming in and out. After the phone sleeps it will come back and I will not get internet some of the time.
I dont know if verizon blocks you if you are not running the newest OS. What could be wrong with the phone?
What do I need to share to find the issue and get it resolved.

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 )
