changing the network type on Nougat - ZTE Axon 7 Questions & Answers

Hi all.
I have the A2017. Before Nougat came out, I was using the US firmware (B29).
I was able to change to network type to LTE only using the service menu (*#*#4636#*#*).
Since 7.1.1 came, I began using the Original, Chinese ROM (currently using 7.1.1 B12).
I still have the same service menu, but the phone doesn't respond to any setting I set for the network type. Only when changing in the Dual Sim settings menu it does respond to my settings, but there is no LTE only setting there.
Can someone who uses the US B19 please check if it works for them? If it does, I will try to flash the US ROM.
Thanks.

Changes in that menu only apply to sim 1. If you're trying to edit sim2, then no go. Still works here (for sim1) on a2017u.

So you're using B19? Then I should too. Because I only have one sim, and it doesn't work for me at all.
I hope it's only related to the ROM and not to the modem, as I do have to keep the Chinese modem anyway.

I'm not sure how that menu works on a 2017G. You could try the app from the play store Network Signal Guru. There's an option in there call change RAT settings. That allows you to change network modes too. It does require root.

No Mobile Data after flashing latest LeeDroid ROM

I just flashed to the lastest LeeDroid ROM. I love it! However, there is no mobile data. I cannot make or receive calls. The mobile data setting is greyed out, I cannot change anything there.
I've tried searching for similar problems with leeDroid, but I have not found much. Does anyone know how I can fix this??

Full wipe and re-flash, and see if that works.
If not it's possible you have an incompatible radio/ril/rom combination; make sure you use the recommended radio for your rom.
I try to avoid flashing radios as much as possible because if something goes wrong, it will permanently brick - so read all the instructions *very* carefully and only do it if you have to!
I installed that ROM too and lost my data connection. But there is a patch, V5.1.1 that'll correct this problem. Just download and flash it in cwm.

Open the dialpad,
key in : *#*#4636#*#*, as soon as you key in last *, Setting Menu will pops up.
>> Click "Phone Information'
Scroll down.... until you see "Set preferred network type", probably set to "WCDMA preferred".
If you are on GSM network, change to "GSM auto (PRL).
Out from the menu... then see whether mobile signal on...
to make sure, re-boot.
Some rom, even set "WCDMA preferred" as a default, still can connect to GSM network some doesn't.... So manually set as above will be the best way, I think.
Hope can be solved, buddy.
sounds like the radio needs a re-flash, flash the recommended or latest one.
Install Latest update on your Rom
zunaedsaki is cooking
im having the same problem. For whatever reason clockworkmob wont let me flash any ROMS at all. i dont understand what the deal is.
Guys, i had this problem on my I9001 but the solution is very simple...
1. Get an android phone (your dads, sister's or brothers or whoever's) and insert your sim in it then browse to APN settings.
2. Copy down the information.
3. Insert your sim back into your phone.
4. Go to APN settings and manually type all the information
you will get your mobile data working...

Installing I-9505 ROM on Verizon Galaxy S4 I-545

Hi All,
I know its a topic which has been addressed differently in different threads. I am a user from India and have a GSM SIM. I have got a Verizon S4 phone. I tried using it with Vodafone SIM and get a problem in using it. Surprisingly a NOTE 2 from Verizon works just fine. I am able to use it for data with 3G but not able to use it for voice. Following steps have been tried already.
- Default Options of using Global Mode and GSM/UMTS ** Doesnt search the network at all.
- Hidden Menu Changes using # codes. ** Shows network but emergency mode only.
- Phone Info app to change the mode. ** Shows network but emergency mode only.
- RF Band change using the hidden menu. ** Shows network but emergency mode only.
It does say that it has GSM radio but cant be used for some software reason I suppose. I checked with Verizon Rep and was told that it cannot be used in India with a GSM SIM and would need the Verizon SIM only to connect with International Roaming.
I was able to install Wanam Lite I-9505 ROM on the phone and patch it with Loki-Doki patch and the phone was booting. But the network signal was not getting picked up. I had data connectivity but no voice or SMS. Is it possible to patch the I-9505 radio over to I-545 and / or force it use GSM as the primary modem.
Any idea for this?

Have you messed with your APN settings? I use a I545 with T-mobile here in the states and all I had to do was change the APN settings

Unlocked GS7 Network Selection menu?

I have my GS7 unlocked. Working on AT&T Network, LTE fine. But at some point I will lose signal and then it won't connect to network until I restart the phone.
Then I noticed...I don't even have a network selection menu.
Is there a code to get to the menu manually and manually set it only connect to the gsm network modes.
Are you using the Stock G930P rom or the G930U one? Cause the G930U for what i've seen preforms the best once unlocked
Stock GH1 g930p....I didnt feel the need to flash the U version. But maybe I will.
I found an app that let me set to gsm/lte

What app?
FYI: Sprint PF1 firmware has network selection enabled, I believe it was disabled thereafter, just like hotspot and apn editing.
Anyway, the app was "Network Mode"

LG H910PR on AT&T LTE?

Hi guys:
i have looked on google etc. but can seem to find a answer. I bought a LG V20 H910PR (from claro unlocked) im using it on AT&T everything is running super fine but can't get 4G LTE only HSPA+. Is that from the phone that does not have all the bands for ATT or is there is something I need to setup?
Thanks,
Did you change your APN?

I will look and see if that model uses the same RSA key. If it does, then you can try flashing the entire AT&T firmware.

Your v20 supports most of att lte bands except band 17, all other should allow you to get lte with att. are you sure the apn is correct, and have you tried forcing the phone into lte mode?, use *#*#4636#*#*, if this menu does not work, download shurcutmaker from the playstore and search for network mode, that should allow you to open the network swtching menu.

Hi, I also have the same problem. The above mentioned code doesn't work, neither does the software you've mentioned. A bit more help will be appreciated.
Have the same problem on other operator. However if I reset the network settings and don't go into the network options it connects to 4G. If I just open the network settings, without touching anything, it locks to 3G/H+. There's no 4G option in network settings as mentioned. My APN is set up correctly. I did a bit of research and found these threads on Vietnamese forum, google translate was not helpful.

Is it safe to root/flash ROMs onto H910PR (it has V10j-CLR-PR software) using the H910 methods mentioned here?

Unfortunately I have the same issue, really disappointing. I'll try messaging the seller on aliexpress or I'll try to get in touch with the service on that Vietnamese forum I mentioned earlier. It is obviously software-side error so I am hoping this can be solved.
Also, you can go to service menu by typing *#546368#*910#.
Edit: After a bit of research I came across this thread: https://forum.xda-developers.com/lg-g3/help/lte-option-network-selection-t2827499
It is for LG G3 but the problem is the same. Basically Field test-Modem Settings-RAT selection - GSM/CDMA/LTE is a temporary fix. Other methods require root.
In the Field Test - PDP Setting - APN setting I have "LTE attach profile" which is hidden in the normal Network Settings menu. Don't know will modifying this to match my carrier's APN will change anything.
If you are still ARB 0, then you can use the H910 method. If you are ARB 1 or greater you will have to wait for the firehose method.

Hello, I am new to the site, something similar happens to me, I have an LG V20 H910, with the AT&T system it allowed me to select the 4G mode in the mobile networks option, now I changed the system for the company CLARO Puerto Rico And I don't get the 4G option in the settings, I only get 2G and 3G. It does not let me enter the hidden menu either, it tells me that it does not work on this device, I can not solve with the combination * # 546368 # * 910 #, I select the option only LTE, the coverage goes away and it comes back in 3G. Please, if someone solved this problem can you help me?

[Q] US996 on Verizon issues

I have several issues with my US996 on Verizon, running LineageOS 14.1. (I'm not asking in the LOS threads because I figure more people here know the details of this device)
The main problem is I can't get SMS to work unless I set the preferred network type to CDMA or CDMA/EVDO only. I have been using the "VZWINTERNET" APN.
Any time I set an option that includes LTE (including the "Global" setting), SMS/MMS stops working.
Also, the signal indicator works strangely, oftentimes when I have strong signal the signal indicator shows 0 bars.
Lastly, many of the fields in Settings/phone info/SIM Status are blank, eg phone number, signal strength and service state. (Perhaps this is a CDMA/Verizon idiosyncracy since the SIM is not the primary auth to the legacy CDMA network?)
Do I need to flash the VS995 radio to this device to address these things? Is that even feasible? What about what Verizon calls "Advanced Calling" options? Ideally I would love to have VoLTE and WiFi calling as well.
Thanks.

If youre device is abr0 you can use the patched dll version of lg up. https://forum.xda-developers.com/attachment.php?attachmentid=4233875&d=1502007613 to flash vs955 firmware. I have found that the this version VS9951BA01 is the one has fastboot mode and can get to recovery if you want to use dirty santa on it. or if you get to the you have 9 attempts of 10 to enter the passcode. you will then need to factor reset to get the data formated. But this link has the full instructions. https://forum.xda-developers.com/v20/how-to/guide-patch-lgup-to-unlock-features-t3652222

Thanks for that tip, I will read up on it a bit later.
The main reason I got a US996 rather than a VS995 is the lack of an officially unlockable bootloader on the VZW variant and having to use an exploit to unlock/root it which only works on old firmware leading me into a potential trap if the device ends up in a state I can't either unlock/root or return to stock from.
I already unlocked the US996 bootloader - will that get reset if I flash a stock kdz onto it?
I tried using LGup shortly after I got the phone but I was having problems getting it to work on my Win7 workstation, perhaps I had the wrong version..
