This issue has been reported numerous times with the Oreo update, suggestions are to use the hidden svc menu to change settings, but reports say that the menu is not accessible. So your going to have to wait for the carrier to fix it. Or depending on your variant downgrade and go back to nougat

I updated my lg ls997 (sprint variant if v20) to oreo, then when I tapped on mobile networks I found (null) value... Then easily changed it to CDMA and it works now.

*#*#4636#*#* doesnt work? I know the other one doesnt but this one should.

[Q] Is it possible to force HSPA or HSPA+ and disable LTE?

G2 seems to have worse LTE reception compared to few other devices I had, is there anyway to disable LTE and go down to HSPA or HSPA+?
I know my area has terrible LTE coverage, but for some reason it sticks to LTE even if it means I am forced to 0.3mbps speeds! Ouch.

You can disable LTE from the service menu,use the code 5457#*(your phone model here)# And you will find an option there with the bands to do so.You can enable only the ones you want and dissable all others.Dont change anything else tho.I cant tell you exactly where you will find it cause the menu is slightly different for every variant it seems.

Thank you so much, I remember now people were running this trick on Nexus 4, but sadly it did not work. When you say Model here, I just put numbers only right? I got the D800 from AT&T, in dialer I just hit 5457#*800# and hit call, nothing happens, I get invalid MMI error. I tried 5457#800# no luck.
However, using your suggestion, I found the code to access service menu, but it wasn't as clear as I hoped it would be so I did not touch anything.
Code:
AT&T LG G2 D800 Service Menu: 3845#*800#
T-Mobile LG G2 D801 Service Menu: 3845#*801#
Verizon LG G2 VS980 Service Menu: 3845#*980#
Sprint LG G2 LS980 Service Menu: 3845#*980#
I expected on/off switches, but there is WDCMA-Only, LTE-Only, and nothing else. There is no HSPA or HSPA+ only or any switch, and I don't want to hit LTE only assuming that will limit the reception to LTE and I will get stuck with no coverage when there is no LTE.
On Sprint, I can go into data settings via dialer (##3282#), and edit LTE screen (requires service code). From there, I can disable LTE and force CDMA/EvDo. Of course, this is on Sprint variant, not sure how AT&T/T-Mobile does it or whichever carrier you're on.

I am on ATT and I can't find this setting anywhere.

I also tried *#*#4636#*#* which does not let me go into OEM-Info or any Radio selection.
Why does AT&T do this!?
I believe if you go into settings and go into the mobile networks menu, there is a menu that allows you to choose whether the phone will go into LTE if available or just stay on 4G HSPA+. I'm getting my G2 tomorrow, so I don't remember exactly how I did it when I played with it in the store. If you can't find it, I'll let you know what it is once I get my phone. This is with the T-Mobile G2.

In order of Nice to Naughty,
Sprint
T-Mobile
AT&T
Verizon (wayyyyy low in the list, naughtiest)
So, considering above, I am pretty sure A&T disabled that menu you are referring to (In Mobile Networks) some confirmed it working on Sprint, but I don't think it is available on AT&T. I am stuck with LTE.

Sorry, missed it earlier when you said you were on AT&T. Are you able to go to Settings > Tethering & networks > Mobile networks > Network mode? With the T-Mobile version, there's gsm/wcdma/lte auto, gsm/cdma auto, wcdma only, and gsm only selections under the Network Mode menu. That would really suck if they diabled that setting. I'm assuming you're on stock unrooted.

Service code for the d800 is 3845#*800#
Go to LTE settings, modem setting, then select RAT then you can force what ever mode you want.

There's no RAT selection for me under the LTE modem settings. I have LTE Band Selection, VoLTE Radio, Null Integrity, and LTE-A CA.

[Q] D80210f-SEA, LTE issue.

Hello everyone,
I got a Singaporian version of the LG G2 (SEA) and today I updated it with the last version of the firmware : V10f
The problem is that i can't reach the hidden menu anymore, applications that can switch on/off LTE data are not working anymore and I can't switch it directly from the network menu (I can just select : GSM or WCDMA (2G or 3G in french))
Someone has a solution ?
Thank you very much and sorry for my weak english
http://forum.xda-developers.com/showthread.php?t=2494751
I'm guessing it's enabled on a carrier basis within each firmware - I'm on the same SEA firmware, but I have the option for LTE in my options:
Hum in fact I can activate the LTE by the hidden menu (3845#*802#) but I dont have it in the network menu, I didn't understand what you said "enabled on a carrier basis with each firmware" what does that mean ?

Lg g2 f320l no network mode option

I just bought an lg g2 f320l u+ korean version. . I was impressed by the specs prior to buying the phone. But yesterday i found out that this phone doesn't have any network mode option under tethering and network menu. It is stucked to G (gprs)
Which is super slow. I tried #*f320# but it's not working.. i also tried the #*4 something. . It didnt open.. i also tried the other code which will bring you to general hidden menu. I kinda regret buying this phone.. everything seemed perfect except the data network option. I just want to have at least hspa+ network.. btw this phone is 4g lte capable.. but just can't find the option to turn it on.. please help me.. thanks in advance.

Lg g2 network options
You have to root your phone to be able to access system files after which you can edit build.prop files. The problem is in one of those files it will open up the network options. +256794277450 hit me up if you get stuck
I have the same cell too.. I lost the option where it had Network Operators list from there one could select jazz 4G, Warid 4G etc.. Plz guide where it is now? I inserted 4G sims of Zong and Jazz in it.. set APN too.. yet failed to get 4G but i remember it had somewhere "search network operators manually" option in it. Plz help.

That is the correct behavior... if you dial *#*#4636#*#* and go to Phone info and scroll down, is your "Set preferred network type" set to "LTE/GSM/CDMA auto (PRL)"?

Reboot into Safe Mode and try it... Press the power button until the Power Offn button appears, then long press the Power Off button and in the "Reboot to safe mode" screen, select OK. Once it is rebooted into safe mode, test again.
Are you stock, rooted, or running a custom rom?

Hmm... Odd... I haven't heard of this issue on the X. Any chance of trying with another SIM, say borrow one from a friend long enough to test, or getting a replacement?
Otherwise, factory reset and test again.

I already done that the factory reset do not work, and if I change the sim to my old celphone (moto X 1) works perfecto, when I use a sim fom Telcel ( another service provider) the phone works normal, its weird because should be the same Ting, the only diference that I see is that the signal bar change from LTE to 4G (I touthg that was the same) with the Telcel provider.

The Style will show 4G instead of LTE... It's normal I believe. You can verify with LTE Discovery or Network Signal Info app, but I don't think it's relevant. Sorry, but I'm running out of ideas.
What version Android, firmware, and radios (Build number and baseband info)?

I think that there is all the information that you ask if not, let me know. And thank you So much for your time
I ran into a problem where I couldn't connect to the voice network but data worked, and I discovered that I had accidentally flashed the US modem firmware when I changed ROMs. This probably isn't the case here, as its fully stock, but I think it's worth mentioning. Go to Settings->About Phone->Status->SIM Status and make sure that both voice and data are labeled "In Service".
Ok might need expansion of problem explanation, but here's the deal.....
If getting LTE on and off call, that's true LTE your carrier is supporting.
If getting LTE when not on call and H+ while on a call, then your carrier does not have VoLTE enabled and this is normal. H+ should be plenty fast.
However, if you are getting LTE while not on call but 3G/UMTS/CDMA1900/EVDO/edge/etc(2-3g), then the same rule as above applies, only difference this time is the tower you're connected to does not support H+ or your phone does not support your carrier's H+ frequency.
Who is your carrier?

On LTE/GSM/UMTS mode, mobile data is working. but Only CDMA mode can't work.
Anyone, Has my same problem?
I need help from everyone. Thanks.
I'm confused. Have you tried setting it to LTE/GSM/UMTS/CDMA mode?
LTE/GSM/UMTS mode isn't going to connect to CDMA at all.
There is no LTE/GSM/UMTS/CDMA.
