My Huawei P8 - Android 6.0 used to be set to use 4G network, it was set in automatic mode 4g/3g/2g
something like this, if I remember correctly: "Preferred network mode 4G/3G/2G"
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
For a test, I switched it in 3G mode, so now the setting is "Preferred network mode 3G/2G":
Now the problem is that in network mode selection, I have no option "4G/3G/2G". only "3G/2G auto" - "3G only" - "2G only"
How to revert to 4G mode? I read around that I can use Settings > Backup & reset > Network settings reset , but according to this link, it resets too many things
Here my phone infos
I assume this is a just a bug in the user interface, not showing the desired network mode
Is there a way to work around it, maybe manually editing some configuration file? or even better some hidden setting screen that I can use?
I'm on a rooted device and can use Adb (not an expert, but I can use it somehow)
Originally posted on Huawei P8 forum, I post it here as well since a possible solution will likely be not strictly related to P8

I'm wondering if I should use the LTE On/Off toggle or the built in toggle in the settings menu. The reason I ask is because after flashing the 906 radios this is what I have for a selection:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Now should I put it on unknown or on CDMA (PRL) and control it from the settings menu?
I know there use to be options for LTE on that menu, but I do not have them. :/
There an LTE toggle on the market specifically for the Thunderbolt that works well. It's just a shortcut to the settings menu, but it's pretty easy to be quick with it. There are no actual 4G toggles for Android yet due to security design by Google.
As for those options you have in the quick settings menu, I dont think any of those correspond to LTE. Those are usually thrown in by the rom chef, and often dont even do anything with your model phone. The real suite of options should be buried in the wireless config under android system preferences.
Lte onoff....
I would suggest skyraider 1.3. It has a built in 4g toggle and is the smoothest 2.1 rom I've seen. Its not on XDA though so you would have to do a google search.
Hi everyone,
I've got a weird problem with my Nexus 5.
A couple days ago I flash Android L preview, everything was Ok. Yesterday I wanna go back to Paranoid Android (my rom), so I wipe my phone, I had a couple of problems, but I resolve all of them. And everything was ok.
In the evening I change my favorite network type to 2G, after that my N5 wasn't to join my carrier network.
This morning I flash the factory image that I grab from Google website. That change nothing...
I don't know what to do...
Here is informations displayed in fastboot :

"lightbox_close": "Close",
"lightbox_next": "Next",

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Here is the "Network Settings" menu :
The "Preferred network type" selector (I never see one like that before) :
Thanks for your help, if you need more information ask (I know adb and fastboot).
AMDG2
From your screenshots it looks like the preferred network type was set to something that is not one of the default options. That selector in your last screenshot is the stock Android selector. Just choose LTE and it should get you connected again.

cant set data apn in smart
j700p apn use Shortcut Master Lite apk and search for apn then enter yours and data worked for me no rooting needed.
I just bought S20 Ultra. My service is thru Total Wireless but it is a Verizon phone. I bought a new SIM and went thru all the hoops to activate it but I have no data, and no messaging. It shows 4G LTE on the top but it is greyed out. When I try to make a call it shows 1X. Also when I go to APN settings I can not add or edit and it displays "APN settings are not available for this user" I spent 11 hours between CHAT and Phone calls with Customer service. They had me factory reset twice, reset network settings, power on with and without data/wifi/roaming and or airplane mode on numerous times . They said they were updating my APN settings every time and pushing something thru to my phone but none of it worked. I tried to put a non working sim from T Mobile in and then add an apn but every time I would change the MCC it would disappear when I went to save. I don't know what else to try but I am hoping one of you might be able to help !!

Hi i would need a screenshot of the QPST tool at its default in each tab, in the programming section (PLEASE CLEAR ESN IMEI MEID before posting!).
The main one i need is attached here (UMTS System tab). I mistakenly touched something and now i'm in troubles... i cannot use 2G or 4G: if i enable one of them, i've tried enabling both but without success...

EDIT:
Please it's simple,

(https://www.mediafire.com/file/220h5xaxi1gd55m/QPST_2.7.496.zip/file)
dowload engineermode, install in in your oneplus 6
(https://www.apkmirror.com/apk/onepl...-0-171117173719-25c8842-android-apk-download/)
go on telephone dialer enter *#801#
use engineermode
if you are on OxygenOS11 click on rndis,diag switch and put it on
if not try rndis or full-port switch (not both)
connect your oneplus to the pc
open QPST configuration; it should appear one device SDM845
click start clients, service programming
select the only active device... (SDM845)
press ok
click on read from phone (click ok if a popup asks for a code)
post what you see in each tab here (delete ESN MEID)
UMTS System tab is what i need ASAP
Thanks
