D802 2G only - G2 Q&A, Help & Troubleshooting

A friend updated his device to V30a LP rom and as a result the devices works on 2G only and doesn't show any 3/4G networks
what could have gone wrong?

Check the Network Mode in Settings. Settings -> Tethering & Networks -> Mobile Networks. The network mode should be set to "GSM/WCDMA/LTE Auto" or "GSM/WCDMA".

Doesn't look like anything is missing to me...

Not really, never even thought about disabling LTE before I read your post, but I had found Tab/List view feature for the System Settings after I started monkeying around with phone, got it on Monday BTW...
When you have the System Settings open, tap the menu button to select between list and tab views. I like list because it puts most things in order similar to my ol' Samsung phones. :good:

i have installed italy rom and it says >>> EURO "D80220b-Euro-xx" and
no lte option
lte only says " not supported" in hidden menu
no knok code
i have also tested german >> "D80220D-euro-xx"
no lte option
lte only says " not supported" in hidden menu
knock code avilable
ALL of voice software say "unfortunately stopped working"
i think no lte most be one of these things
1-your phone IMEI
2-your phone rom
3-your network provider
OR MANY of these
finally my solution : after buying many LG product i found LG is such a waste of money now ... i am going for Samsung or htc

Carrier switching - Note 3 LTE

Hi
since i flashed my n9005 with 4.4.2 i have problem with carrier switching,
i use carrier that allows to connect with network by two ways:
by mother carrier - let say nr 1
or by two other carrier with domestic roaming - networks 2 and 3.
when i use my network 1 - i can connect with LTE speed, while in roaming only speed H is allowed.
And my problem is when i manually connect with network 1 my phone keeps switching to 2 or 3 after loosing signal even for few seconds - in elevator or staircase.
I wanted to lock it on my network by i can't.
Didn't have that problem with Note2 LTE...
is there any way to lock on single network, i don't have option to disable roaming, there is only option for data roaming.
Have you tried just going to settings --. connections --> more networks --> Mobile Networks -> Network Operators --> selecting the #1 network? If you select one here, the phone should turn off Auto switching and it can't change to another network unless you select one manually via this method. Or at least, mine remains on 'no service' untill I select another when crossing the border.

I did, i have to do it every time it switch - i switch back

Can't switch back to 3G or LTE. Left with only 2G connection.

Facts:
- OnePlus 2 (European Edition, Germany)
- CM13 (13.0-20160721-NIGHTLY-oneplus2)
- Provider: Telekom (Congstar)
My OPT refused to switch to anything more then EDGE (2G) a few days ago. First I though the network was down but after a few days I checked with other phones and only mine wont switch to 3G or LTE.
When I tried to cheange the "prefered network" toggle, I switched it to 2G and now I can't switch it back to 3G or LTE. The options are still there but when I select them they instantly switch back to 2G. Even in the Advanced menu that you can enter by dialing *#*#4636#*#* I can't change it. The setting is fixed to "GSM only".
When I search for network I can only find 2G networks. In the Results are only Vodafone 2G and Congstar 2G which is my provider.
Does any one else have a similar problem and maybe a solution?
UPDATE:
I reflashed the stock image and everything worked there. Then reflashed cm13 and now I have the same error again. So it seems to be a software bug in cm13 not a hardware bug.
UPDATE 2:
I flashed the modem from stock again. Still not working. Than I disabled the modem from the service menu and enabled it again. Then it worked for a few days but then I was back to only 2G. Now the reflashing trick doesn't seem to work anymore.
I have no idea how to fix this does anyone have a clue? I can't be the only one with this problem.

You can't have 4g/lte active on both SIM cards, so solution is to put phone in flight mode, switch your primary SIM to 4g/lte which should put your secondary into 2g mode and then you're set.

What he said.
That's how I fixed it. Still wondering why this is possible with the stock firmware. At least I didn't notice the problem with stock.

because on stock it does this automatically. You can change the network type of the SIM on which data is enabled.
The other one wont even show you the option

[GUIDE] [FIX] Unstable 4G/3G Network On OxygenOS [No Root]

If you use a OnePlus device specifically a OnePlus 3/3T then there's a really high probability that you've been effected by the unstable network problems(Data network automatically switching to 2G or 3G when the 4G signal becomes a little weak even though the device is capable of receiving the signal) caused when the signal strength is very poor. Even if you select 4G/3G only in the settings the signal becomes 2G.
If you are getting affected by this issue then you can solve this just by installing an app from the play store.
STEPS-
1. Install the app " JOnePlus Tools".
2. Open it and then click on "More Settings" icon on the top right corner.
3. After that click on phone info.
4. In phone info select drop down menu and choose the option, "LTE only" or " WCDMA only" according to your need.
5. Done.
I've been testing it for a few hours now and and haven't faced the issue.
If you are still not able to understand what to do then watch this video, everything done step by step.
But if you choose LTE only when there is not LTE the mobile signal is lost right?

This does not seem to work any more. I think since Android 8.
I tried the OP3T Cellular Settings 1.1 as suggested, but that didn't seem to work on my OnePlus 3T (Android 8.0.0).
However the Dial *#*#4636#*#* and in "Phone Information => Set Preferred Network Type:" as suggested by @lover, and then using LTE only worked perfectly. Thank you!

Try dialling *#*#4636#*#* and select the first entry (Telephone information). You can set your preferred network type there. On my phone there are a lot of options to choose from, including LTE only, WCDMA only, etc.
