No LTE after 8.1 update - Nexus 5X Q&A, Help & Troubleshooting

After updating my mom's 5x on sprint to 8.1 she no longer has lte. Phone is not rooted, she is in a native lte area, had lte immediate before pushing the update button. One strange thing is that prior to 8.1 but only after previous update, if she lost lte in a bad signal area the phone would not grab lte again until the phone was restarted. Prl and sprint provisioning were all up to date.
Any one else see this behavior?
I have not had a chance to backup, wipe and start over, nor will I for another 2 weeks. The only thing I could think of is hopefully a factory restore will help.

Did you try *#*#4636#*#* on the Call App ? With that you can go to "Phone information" then you can select the preferred Network type
Maybe LTE wasn't selected after the update ?

Yeah I tried that. It was set to auto, I changed it around a bit but no luck. Hopefully I will be able to reset it soon.

Same problem. No LTE after update to Oreo on Nexus 5X
I've been researching this problem through the internet and a lot of people have this problem and the only reason concrete solution is to get a new phone or replace the motherboard, which is the same price as a used Nexus 5X. Unfortunately, the 5X was a lottery where 1/2 of them had motherboard issues.and was stuck in a bootloop. I had one that Google or LG refused to replace since I live in Croatia.
So did you figure out a software solution? A better radio firmware perhaps?

[Q] Thinking about exchanging my CDMA GN due to LTE signal drop

I've been using the Galaxy Nexus for about a month or so and have recently started to notice that the 4G signal will drop whenever I turn on the screen after some time in deep sleep. The signal meter will be fine, until I actually try to use some data. It typically takes about a minute to reacquire a signal, but the phone is essentially useless during that time.
As you can see in the screenshot, there are several red spots where the signal dropped out. I am not in a poor coverage area, and others with the same device do not have these issues. I saw this with a rooted 4.0.2 OTA and am still seeing it with a rooted, deodexed 4.0.4 rom (http://forum.xda-developers.com/showthread.php?t=1481613).
What do people think? Will exchanging the phone possible fix the issue? Is there anything Verizon can do to try and help me out? I'm basically just spitballing here, but this problem is making my phone very frustrating to use.
Are you rooted or stock? I don't have any issues with my 4G on stock or rooted with Gummy 0.7.6. I had an issue with an earlier root where my 4G would drop. I would disable / re-enable and it would start to work again. Maybe try rooting if you are not rooted????

Yes, I see this on rooted stock, as well as the ROM I referenced in the original post (supposedly deodexed 4.0.4 stock ROM)
EDIT: From several posts in the other thread, this issue is not isolated to me or my hardware so I probably won't bother exchanging the phone.
History of Signal ?

Can you please tell me where you get that HISTORY screen from. Ive checked all menus in settings and I can not find it anywhere.
EDIT... Please ignore my post... I found it...
So, I'm having the same exact problems but i did a log cat to see what might be culprit.
I have narrowed it down to this:
02-08 11:21:51.912 E/IMSFW (415): IIL: Disconnected from '7467' socket
still have no idea what can cause it yet.
also if you switch to 3g it seems it doesn't happen so maybe its a sim problem on verizons lte network end?
11:22:40.029 E/IMSFW (415): ImsSMSInterface: Registration failed, go for retrying if isim nounce present
that's what i found so if anyone can clarify and maybe see if it is really on Verizons end as this is the 4th phone that has had this problem.

Hey fellas, I'm posting in this thread because it relates to the issue I'm facing. Coming from the Thunderbolt, I had no problems holding onto a LTE signal in Atlanta, but with my GNex, the signal just drops a lot (every half hour or so maybe), at work, at the store, wherever. It shows an empty signal bar with a small x, and says 'Searching for Service'.
This seems to happen only when I have it in LTE mode. I switched to CDMA under the 'Mobile Networks' settings window, and it was able to hold on to the 3G signal all day. I am starting to think if it is a LTE sim card authentication issue.
I'm going to VZW to see what I can do (I'm still within the 14-day window).
I'm having the Same issue holding onto a 4g signal in Savannah and Atlanta, cdma only is fine. Let me know what Verizon tells u cause they basically told me to wait for an update

Just came back, basically they said they can't do anything unless they replicate the problem, which they couldn't. (it was a random problem.). They told me to call customer service when I got that issue, so I have to see that at work tomorrow.
I tried a suggestion online where I updated my prl from the 15xxx version to the 52642 version. I did this by creating a contact with the following number
*22899
and dialing that contact. It went through a 'activation' process, with some elevator music, and the signal seems to hold.

I've updated to 4.0.4, 4.0.3, flashed just the radios, removed some card, hard reset, factory reset, just about everything u can imagine and still no luck. I'm tempted to file a claim with asurion(purchased gnex from a friend) and see if another gnex works with late but I don't wanna spend $99 for nothing

To this and post 10, I still have those data issues, but they are much less frequent on the 4.0.2 radio than the 4.0.4.
I got in touch with Verizon wireless online support, and they basically told me to wait till they release a software update. I asked for a new sim card (since I thought it might be LTE authentication issues), and they said it was a software problem, not a SIM problem.
I guess its a wait and see.

Rooting issue or just coincidence?

Hey guys, I just a sprint gnex phone a few weeks back and ran the GNex toolkit v9.1 to unlock and root it this past saturday so I could use a hotspot app for my tablet.
I don't know if this is just a bad coincidence or if I did something wrong..I'm not new to roms and have modded my previous phone (evo 4g) about 50 times, but here's what's happening.
Prior to this weekend I had full signal/bars..Now I can barely get 2..It's mostly sitting at 1 bar and sometimes drops the connection entirely. At the same time, every txt msg I send comes back with an error stating it did not send, however...It does actually go through, twice even. This happens with every text to every person.
I didn't put a rom on it, and I didn't even install clockwork mod...I simply just unlocked the bootloader and rooted it. I did setup google voice afterwards. I can't see how doing this would cause these kind of issues and I haven't called Sprint yet as I absolutely despise their customer service..I'd rather get feedback here first.
The coincidence that I'm referring to is that I'm in Austin, Tx and they're in the process of spinning up 4g LTE towers right now..If by chance they started upgrading my tower this weekend (yesterday & today) then I could definitely see these issues...I walked down about 2 blocks where I do get a full 4g signal, but my txting still had the same issue.
Any ideas or thoughts about my problems?
On one hand, I would tell you that rooting doesn't cause that.
On the other hand, you used a toolkit, so who knows what you ended up doing.
If you haven't changed anything as far as ROMs or mods, then I would suspect you're right about something with the network. The only other thing I can think of would be hardware problems of some kind. That seems a lot less likely though. Sprint does supposedly keep a list of networks that are being worked on. You could check in with them and see if the one in your area is being upgraded.

I do know they are upgrading the towers in my zip code to LTE 4G..I'll give em' a call tomorrow and see what they say.
This was the toolkit that I used.

happened to me.
Reboot your phone and go to about and sprint system update.
update profile.
Idk why but its sometimes happens for no reason.
Make sure you have good connection first.(go outside)
If that doesnt work update prl to make the network find the closet tower to you.

I was trying that repeatedly hoping it would fix it..but it doesn't.
On another note, today when I woke up and rebooted the phone I had full bars on 4G signal..Thought life was good and then about 5 mins later it was back to 1 bar 3G. That's the first time I've seen a 4G signal here in my apartment so I'm hoping it really is just the towers in my neighborhood being converted to 4G right now.
I've rebooted my phone 3 times now and the same occurrence happens..Full signal with 4G for a few mins, and then it drops to 1 bar 3G..Have updated my profile and PRL and tried airplane mode..Only way to get that 4G signal back is to reboot the phone..Won't stay on 4G though.

[Q] Cannot stay connected to any LTE bands. Need advice and ideas please.

Okay, here's the problem. Since June 3rd my phone will not stay connected to 4g. I toggle airplane mode and I instantly lock on to 4g. Signalcheck reads between -109 and -115. This is normal for me at home. Until the 3rd I could hold that lte 1900mhz (band 25) and never drop it unless i went further into my home. I almost never get band 41 unless Im closer to a tower. Band 26 is nonexistant in Buffalo (too close to canada).
Since then I toggle airplane mode and can lock on to LTE 25 (same signal strengths) but it drops to eHRPD 3g every single time.... Within 10-15 seconds. Same happens when I reboot.
I am running full stock, stock recovery, ZVG, and the G2 is rooted.
I have tried:
Disabling band 26 and 41. And connecting to any combination of them on/off.
Modifying the bsr timer, etc.
Updating prl, profile, and even reactivation many many times.
Factory reset on ZVG, 3x.
Full TOT back to ZVE, unrooted. (Still same problem even on ZVE, unrooted and yes I never had this issue on ZVE before updating to ZVG the first time.)
Redownloaded ZVG and reinstall after TOT, no improvement.
Called sprint and have been working with engineers in Oklahoma city office. They swear up an down its not a tower issue, or a eCSFB problem.
I have the same problem even away from my home towers.
I have opened the device to inspect for damage, or moisture, there is none I can see.
I havent dropped it hard, or exposed it to any water that I can think of.
So anyone have any ideas on what I should try next, or do to get my 4g to stick?
Im a bit at a loss. Ive tried every setting, trick, or troubleshooting step I can think of.
Thanks in advance for any help or knowledge you can provide.
For anyone that may have a problem like this in the future I solved my issues by having sprint send me a new sim card. Being that I bought my g2 the day it was released I guess maybe my sim went bad. It was a long shot and my last ditch effort to get 4g back. I now have a steady 4g signal.
Thanks for posting what fixed it for you. I've also been having this same problem for about the last 2 weeks. It just won't hold LTE. I'll stop by my local Sprint store today for a new sim and hopefully that does the trick for me as well.
Unfortunately even with the new sim card the problem returned after a few days. I called Sprint and asked them to put in a dummy sim number to unregister the sim, and then re-add the sim back. It fixed the problem immediately once again.
Frankly, I dont understand what the problem is. I know its related to the sim card but I havent reset (powered down) my phone in a week. Im kinda worried the problem will come back if I do. Cant see it being a bad sim reader in the phone. Otherwise it wouldnt start working on 4g again after resetting it via sprint.
Im stumped.
I can always call sprint and have them reset the sim again but Id rather know if its some kind of bug that will be fixed. I contacted LG and they acted like I am outta my mind.

3G?

Does anyone one else have an issue where the Verizon G4 get stuck on 1 bar at 3G? All of the rest of the phones in my house have full signal and 4G
Any idea how to resolve this? I have tried to reboot, I would really rather not update or factory reset but I am guessing those are the only options.
Is the phones running by the same carrier as your g4. If not there there u go
If it is i saw a poston here soneone is stuck on 1x for a bit. It take time for he phone to switch networks. Mine dose it at times
network switching doesn't appear to be the fastest on this phone. I'm sure there will be updated radios coming out which should address this.
They are also on Verizon. I also notice the wifi sucks on thethe G4 as well compared to the others.
Hopefully they will sort this out with an update.
Any ideas in the meantime?

After October Update - No LTE

Hey guys, just did the October update this morning and now I can't get LTE. Icon just shows 4G. I've tried several restarts and cycling airplane mode and mobile data to no avail. Anyone else experiencing this?
October release? What's the build number? I don't see an October update anywhere.
Are you mistaking the hot fix for the October update? The October update won't be until next week.. it's always the first Monday of every month.

I am on AT&T. Version # is QP1A.190711.020.C3. It probably was the Hotfix.

There is. My Gf received the OTA yesterday.. I did as well. We are with T-Mobile. However, my bootloader is unlocked and I'm rooted so I ignored it. The security update will be next week, so I figured I'll wait to apply any updates.
4G and LTE are the same thing. Do a speedtest to check if you find the same speeds, but it's very likely just some regional assets not correctly fetched by the OS. The only reason why some builds show LTE in some countries is because of some very bad advertising from some providers (in the US for example some of them did that) where they called "4G" what should have been known as 3G+ (even though it was the same base protocol as 3G).
I'm seeing the same issue. Ran speed test and it's only hitting 10-12 Mbps. I'm also on AT&T. This happened after I updated today.
Flashed over with .020 and still having issues. No luck on the LTE.
I downgraded to .019 and was able to get LTE back. It automatically updated to .020 and I lost LTE again.
I had to downgrade back to .019 to get LTE back again. I turned off automatic updates in developer mode for now until the issue is gone.
xomikronx said:
Okay I figured out the issue. Hopefully this helps everyone here.
There are two updates from September, .019 & .020.
.019 is for all other Pixels.
.020 is for Verizon Pixels.
When the update for .020 was automatically applied to our phones, this is what broke LTE.
I didn't try updating from .3C to .019 to see if this would fix it. Maybe someone can try and report back.
What I did was just clean flash the .019 on my phone. Once Pixel applied the additional small update for Oct. I still have LTE.
Basically, we all on AT&T flashed the wrong firmware.
Good luck!

I have a Pixel 3 on AT&T. After the last hot fix I noticed that my LTE notification changed to 4G. I prefer the LTE icon as it is more informative that "4G" which has little meaning anymore. I ran a network signal info app and I am on actual AT&T LTE and my speedtest is 118 Mbps up, 6.7 down with 19ms ping. So am pretty confident that I am actually on LTE just that the icon changed. Based on your post I looked at my build number and it lists QP1A.190711.020.C3. So I guess I have the .020 that you reference.
Are you sure you did not have LTE and it was not just an icon issue? I don't really feel like flashing different firmware so might just live with the 4G thing unless the "wrong firmware" will cause some actual performance issues...

Same here. I have good speeds, just trying to figure out why the icon changed after the flash. Since the firmware was pushed to my phone does that mean Google is pushing the wrong firmware? I know this is not a regional issue because I flew around the whole US over the last two days with no change. I also reset my network settings with no change.
4G = LTE on AT&T.
If you are ever in doubt, do: *#*#4636#*#* from the dialer and select phone information.

I agree but I have always been on AT&T and through every Nexus and Pixel my notification bar always read LTE not 4G. My wife's P3 is on Google Fi with the latest update and it still reads LTE. I will check what hot fix build she got tonight. So why would my phone (and others here) read/indicate 4G now?
As I said, probably just an asset being fetched inconsistently. I know for a fact in other parts of the world it never says LTE but just 4G (because less bad communication around it here), so the system pulling one or the other is just up to how it associates the connected network to a region that says LTE or one that says 4G. My best guess would be that AT&T was misplaced in the last update for some reason that I can't imagine. ¯\_(ツ)_/¯
I lost my LTE this morning.
Had to "disable" the Google eSIM.
Then re-enabled it and LTE came back.
Lost it again after a reboot.
Repeated the above steps and it's been solid since.

I had full bars with 4G on .020.3C and was only getting 10-15Mbps. It wasn't just an icon change then. It could also be the spot that I was in.
Anyone else having normal LTE speeds, but only have the 4G icon?

Thats for AT&T and/or Google to answer.
The bottom line is, regardless of what the indicator shows, use the dialer code and you will find out exactly what data network type you are on.
I have a Pixel 3XL and had the same issue. I did a factory reset yesterday and my LTE was good again
