Bug with WCDMA only - LineageOS Questions & Answers

I can't switch to WCDMA ONLY in network type menu. I choose the network type, but nothing happens. No problem with 2G only, WCDMA Perferred, LTE/3G/2G.
But I could easily change the network with *#*#4636#*#*. But after a reboot, it's returns the network that is choosed in setting (usually 2G).
My device is d2tmo. I tried all LineageOS based firmwares. All of there with this bug.
Can you help to fix this problem?

XMD 2004/2005 - Network Mode -> preselection with sim2

Hi,
I`m using my XMD (Android C2004_15.5.A.1.5) with two SIM cards active
I have a problem with the Network Mode Preselection Settings.
I`m working with two different modes for Network Mode Preselection.
On mode A without a problem, on mode B with a problem.
Network Mode Preselection - Mode A (without a problem/error):
SIM1: WCDMA (preferred) GSM
SIM2: GSM only
It is working without any problems even after the mobile phone is switched off and on again .
Network Mode Preselection - Mode B (with a problem/error):
SIM1: GSM only
SIM2: WCDMA (preferred) GSM
There is a change of the Network Mode Preselection after mobile phone is switched off and on again.
SIM2 preselection is changed automatically to GSM only mode! That change will reduce the Mobile Data Speed extremly.
SIM1: GSM only
SIM2: GSM only
Any solution for that problem ?

Back story:
Got used unlocked rooted Galaxy Nexus Toro from friend

Flashed CM 11-20140913-NIGHTLY-toro AV:4.4.4
Flashed Gapps from OpenGapps Aroma
connected to wifi and completely configured
The Problem:
After I left wifi coverage I realized I had no mobile data

At this point I have no ideas. I would really preffer to not flash my phone seeing as I have it completely set up how I like it, also from what I've read that likely won't help. Any help is greatly appreciated.

HTC_One_M8_GPe_Marshmallow-6.0_MRA58K.H14 -> Voice Only, No Data

I just installed the HTC_One_M8_GPe_Marshmallow-6.0_MRA58K.H14_AROMA-Installer.zip on my HTC Verizon M8. After doing so I can only get data via Wifi, it does not connect to 3g or 4g. I was wondering if this is a known issue if someone could direct me on what steps I should take to troubleshoot. I should mention that even though its a verizon phone I am using Smart talk.
Here are my current settings:
Preferred network Type: Global
CDMA Subscription: RUIM/SIM
Access Point Names : VZWINTERNET.
Network Operators : receive "Error while searching networks"
SIM status -> Cellular network state : disconnected
You used this version? http://forum.xda-developers.com/verizon-htc-one-m8/development/rom-vzw-stock-gpe-5-1-lmy47o-h9-t3212413
Did you do as the thread states:
[*] If you have issues with 3g/LTE data hand off, do a full RUU and do a factory reset with the stock recovery. Alternatively just flash the stock recovery and do a factory reset. Theory is the stock recovery rebuilds NV data. Getting a new SIM card has also been reported to work. Calling customer service and asking them to reset your connection has also been reported to help.
I'm having similar issues but I'm using page plus(Verizon network with Verizon m8 and only text and calls work but no data. Also using Verizon APN any suggestions

Just a quick question. Why were you trying to change LTE On/Off in the Engineering Screen? Were you only trying to enable LTE bands or did you have a problem with your data connection? If you were having data problems before downloading the Field Test app, did you know there are some know data issues with CM13. Did you lose your LTE connection?
Also, what gave you the idea to download QPST & QDXM? Do you have prior experience with these applications?
Also, since you have CM13 installed on your 5x, did you try and restore a backup in TWRP that you have saved to see if it corrected your problem?
Which carrier are you with?

Hello,
thank you for your answare, and sorry for my english.
Before problem phone was new and all was worked, but i tryed make some changes, because i searching solution for changng band and editing priority for diferrent LTE band.
Now my problem with no connection on lte is solve, i write zeros to partition modem1 and modem2 from modem filesystem and modem itself after restart phone reset factory setting, but i dont now where modem took IMEI, because i think IMEI is save on this partition...
-----------------------------------------------------------------------------------------------------------------------------------------------------------
But i still dont understed why, after reboot changes on line ID 06828 and ID 06829 comming back originaly number .
Bestest solution for me wold be if i find in NV parameter band priority according signal strenght. Or some application (IN Phone) for disabling and enabling all LTE band without computer.
My most-used bands is : 800,1800,2600Mhz

Shortcut Master Lite in the Play Store will allow you to access the LTE Engineering to set band priority. Open the app and click the 3-dot menu In the top right corner. Click on "secret code explorer" and allow the list to populate. You will be looking for a numbered code like "3282” or "33284". Click on each one, select explore from the menu and look thru each selection. The one you will be looking for will say something like Sprint LTE bands editor. You can enable bands 25, 26 & 41 and set band priority. When asked to enter your MSL, enter 000000 and tap verify. You can figure the app out. It takes a little time to get used to how the app works. Good luck and let me know if you need any more help.
P.S. I dont know why you would start changing NV values without any experience using QPST & QDXM. You can make a mistake very easily. Be careful when making changes. I would start fresh by fastboot flashing the factory images, bootloader and radio and start over. Just my opinion.
What carrier are you with and where are you located?

Why i start Edit without experience ? It is easy, because i need get experience
Band 25,26 And 41 is not important for me.
I need disable and enable and set priority for 800 1800 and 2600mhz, quickly from the phone...
My location is czech republic and switzerland.

How to disable autoswitch network mode

Sorry, for my bad Englisg.
On stock firmware, when I change network mode to EVDO only, its everytime save this mode. I am enable and disable airplane mode, reboot phone, but network mode EVDO only everytime.
On all Cyanogenmod versions I setup EVDO only and change airplane mode or reboot phone, its automatically change network mode to WCDMA preffered or CDMA/LTE.
Cyanogenmod/LinageOS Roms has way to save selected network mode after reboot or change airplane mode? Or maybe its has adb commands to change network mode from CMD ?
Thanks
