[Q] Managed to get GSM on Ls996..Still awaited for APN and carrier name change

!!!!!!Please do it on your own Risk..I would not held responsible for any damage for any cause to your phone..
Manged to get GSM signal outside US for LS996 Sprint version zv5, still trying for APN settings and Sprint carrier title change
This is what i did..
1) Rooted as per instructions available on internet or under Lg Flex 2 general thread..or site of highonandroid.. search for how to root lg g3, flex, flex2 etc..
2) After rooting installed root browser.apk via playstore or any equivalent market place
3) Opn Root browser which will prompt for supersu rights , allow / grant access permission
4) go to carrier folder and then go to apps folder.
5) Renamed two files which is under carrier/apps as *.bak
4) Added new files used the same files which is used for LG g3 sprint unlock..under carrier/apps (Attached )
5) Insert a SIM card before restarting.
6) Restarted the phone and got the signal bar with calling and SMS working..
Still awaited for APN settings and the GSM carrier still shows as Sprint where i need help
Update : Manage to get APN settings too.:
Install Shortcut master lite click and hold the recent apps button and click "Search"
Search for apn select com.andoird.settings$ApnSettingsActivity and then click Launch / homescreen
Select on the Top Right new apn
Fill this form out with the apn from your provider (If you don't know the apn look it up in google).
GSM carrier still shows as Sprint where i need help..
updates : GSM carrier shows proper names ..it seems had issue with my sim card..
now all working fine with GSM calling, sms, mms, , apn ..too
only thing needs to change the icon where its shows GSM while connected to data ..which can be changed to H / H+ ..which is mentioned in some other threads too..

Thnks, Bro, its working fine.

Could you guys provide a much easier or in depth instructions when editing the files I'm sort of new to it. Also do you know if it will change if you reboot. Also do you know if it will work on tmobile and lte on it thanks again for the help.

updated few notes as in for more clarity..Hope it would be now easy...
Ideally it should work with t-mobile or any gsm carrier unless it has a bad esn or restircted in US. It just disables the lock of sprint in an OS level.

thank you so much will try

do you get full LTE?

now i am going to buy this phone!
Thank you, you gave me a hope

LTE depends on the frequency available in your country but mostly you would not get it would be H+..which is equivalent to 3G..3G+
One of the thread has some updates on enabling the LTE bands..

same with me can't unlock with these two files

After rebooting go to settings...more...mobile networks ..u should see options for GSM only, CDMA, WCDMA only WCDMA / LTE..select GSM only ...make sure once the file is replaced you insert a SIM card before rebooting. By default it selects the Global network options once rebooted. Hope it works for you both.
If needed i can add screenshots which i was able to achieve for gsm signal and the data signal (GSM icon).
i doubt or dont know whether it would work within US

Sprint Phone Activation
hey guys, id like to use this method to unlock but I have a great prolem with this. I dont live in the US an bought the phone there after I read that it can be unlocked. It came completely new to me. It was never activated with Sprint and I dont have any Sprint account or whatever. In Germany we only have GSM based networks. The 'self service' app always prompts me to activate the device but that isnt possible because of the GSM network or roaming or whaterver - even the sim that came with the phone didnt work. Is there any way to bypass this bull**** and get that phone working? Hope you guys can help me out with a good idea. Thany you
Best regards from Germany
Jan-M.91
P.S. if anyone finds a way to get 800, 1800 and 2600 MHz LTE bands working please let me know, just found a guide to get the 1700 MHz band.

Hey guys, little update here.
I managed to unlock using the files AND editig the build.prop from SPR to VZW, works so far. APN and MMS are fine. Big problem is GPS when I activate location settings the phone crashes and goes into bootloop. Only way out is reflashing with LGFlashTool. I tried two times so i fugured out that GPS causes the bootloop, SystemUI also closes during usage, all in all very buggy. I think of flashing another ROM, H959 (unlocked US version) or H955 (unlocked EU version) to get rid of the lock, the Sprint boatware and the 'hands free avtivation' that I cant do because I am in Germany with a GSM carrier. Anyone tried this so far? Hope you can help me out. As mentioned it is possible, I made two calls after the progress I described, but I dont recomend it because of bugs and other issues.
best regards

SM-G920W8 | No Option To Connect to LTE

I bought an Unlocked Canadian S6 recently, and it just won't let me connect to the LTE network.
Model Numer : SM-G920W8
Android Version : 5.0.2
Baseband : G920W8VLU1AOCG
Connecting to the LTE is not even an option. When I go in the Network Options, I get the choice between :
-WDCMA/GSM (auto connect)
- WDCMA only
- GSM only
I know for a fact that I am in the coverage zone, so no need to ask that silly question
I've tried different SIM cards, played in the options a bit, and factory reset the phone about 5 times now, yet nothing seems to work.
Also, when I try to do the update, it just reboots and gives me an Android logo and a failed Icon
I've only seen one other post like this from a carrier's support website, but no solutions were found.
**Update : For a reason, after a recovery, it will connect to the LTE for a bit or until next boot, then go back to what it is now.

First question, who did you buy the phone from? Second, Is it second hand? By default, Wind mobile does not allow the LTE option to be displayed in system settings as they as a carrier don't have LTE. It is blocked by the CSC setting for the carrier. As for other carriers It should leave you the option to connect in settings where you say it is not. If it is a Wind phone, You would need to change the CSC to enable the LTE selection. There is a method to force LTE even without option in settings, but I think it is removed in the latest firmware. Try dialing *#2263# in the dialer. It may bring you to menu that will allow you to select LTE. This is not a permanent method though as it will need to be done every boot. The other way, (If you are in fact a Wind/Mobilicity phone) is to enter dialer and enter *#272*IMEI# with IMEI being your devices unique code. If at all possible, take a full nand and Titanium Backup before doing this and be sure to transfer everything off the phone to a PC. This method wipes everything and I mean everything off the phone buy is a surefire way to enable LTE.

Yes, it was second hand. I didn't ask who was his carrier simply because it was unlocked.
I'll try it tomorrow, thanks for the information

Here is the menu you will see when you type the *#272*imei# code into your dialer. The codes are the carrier names. Mine which is GLW is Wind, BMC is Bell, RWC is Rogers, etc.

Maybe there is no LTE in your area...

It would still be visible in the Settings/Mobile Networks/Network Mode menu which it is not. His problem is more than that.

Sweet! It works :good: Thanks man
Now, would you have any ideas on why the update won't work? I didn't get much into it yet, but I will soon.

I'm not sure why it wouldn't update, but now that you have changed the CSC you can download the update and flash with Odin. Pick your carrier and go to town. The guy running the following thread runs his own firmware host. He's got amazing DL speeds. Usually takes me 6 or so minutes to do the 1.6gb file. http://forum.xda-developers.com/showthread.php?t=3086387

I'm having the same issue.

Connected with someone selling a G920W8 version. LTE is disabled and the codes aren't working. Can you reaffirm which unlock code worked for you? I'm on Fido, what LTE network are you using?

hi BCSC
Thanks for the details. I searched complete net and read all articles but nothing set me up with the proper thing. i read your solution i dialled *#2263# and all i got is service mode and in that i went to band selection , LTE and the all ....... Yes and its showing LTE in mobile data. THanks so much.
But now another issue, network is showing perfect but no outgoing and incoming calls.
in incoming its showing busy and on outgoing its not connecting to another phone.
And, Lte is not showing in mobile networks, There only 3 options still are showing.
Mine is same Wind S6 but i had to use in India.
Let Me know
Thanks once again
Cheeerzzzzz
Varun

Picking LTE from the service mode will note make it visible from the settings menu. Its more of a workarpund instead of a way of permanently enabling it. As for the issue of no out/in calls, my best guess is that it could be due to which LTE bands are being used or are available in India. Unfortunatly I have no way to test that option. I only was successful in getting the Wind LTE option on Canadian carriers.

One Plus One Signal Error Problem

Hi there!! Well my one plus one had the problem of the continuous restart, and solve it, following the steps of the htcmania tutorial from reboot (i am new so xda doesnot allow me to post outside links)
Everything is perfect, everything works again. The problem: It does not detect the Telcel sim. I am from Mexico ,by the way.
In Settings -> Mobile Networks -> Preferred Network Type, select 3G (if I select LTE does not recognize anything), then:
Settings -> Mobile Networks -> Network Operators
when selecting this option I only see Iusacell 4G and Nextel 3G (the others companies in the country) and, very often from Telcel, and when I select it (with a Telcel sim inside ), it says: Registering in Telcel,then throws an error saying that it can not register the signal.
in:
Settings -> Mobile Networks -> APN, has Telcel Edge selected, and Telcel MMS configured already.
The rom that was installed doing the tutorial that I put is:
CyanogenMod version
11.0-XNPH30O
Android vesion
4.4.4
Kernel version
3.4.0-cyanogenmod-g7389215 build04 @ cyanogenmod # 1 Mon Aug 11 15:50:37 PDT 2014
What do I need to do to get the sim's signal? Can someone help me please?:crying:

Deleted

Noticed sim problems on my one plus one 4G and 3G running an Oreo ROM and using FreedomPop. It works and can connect as normal, but call quality is pretty poor and probably unrelated. Curious if anyone has similar poor call quality? Sorli....

Curious what baselines have you tested. For instance, my One Plus One uses GSM and that means I can use anyone's SIM card and from other providers to see if my problem is SIM specific (faulty sim card, sim slot failure, or installed upside down).
Do you have friends who Sims work that you can install in your phone and test your phone hardware and software? Thankfully, I have wife and can easily swap SIM cards and test my configuration quickly. Worth seeing what you get and this should help baseline your configuration.
Side note, found my cell problems and lack of signal related specifically to the building (metal roof, concrete walls) and I'm actually shocked how different phones using same service get such different call quality. I'm not talking bout huge differences in smartphones and one phablet having larger antennas compared to another. All are about the same and performance simply fluctuates depending on location. Nothing knew here and I personally can't use my smartphone in buildings unless they're using Verizon or similar services.
Sorry for the long reply, but maybe it will help you resolve your problem! Sorli...

If you are on kitkat 4.4, try updating to a nougat rom, this is really stable and updated:
https://forum.xda-developers.com/on...m-kernel-unofficial-lineageos-14-1-3-t3626403
BUT ATTENTION: this rom doesn't come with an updated modem, so also flash a newer modem firmware :
https://forum.xda-developers.com/oneplus-one/general/firmware-modem-oneplus-one-lollipop-t3300907
DI.3.0.c6-00241 - latest "stable" modem, try this first
4.0.1.c7-00011.zip - alpha modem, someone says it's better, others says that it causes problem, you have to try it yourself.
Hope this will fix your issue!

VoLTE not working

Hi, I had Poco F1 before with working VoLTE, so I know that my carrier and current Sim card is supporting it. All I had to do on the F1 was typing in that code *#*#86583#*#* and activating the new volte setting.
I tried that with the X3 but it's not working. Whenever I receive/make a phone call my connection will switch from 4G to 3G.
Is there a workaround or is it a hardware limitation? I could imagine because the X3 just has an entry level SOC that the modem has some artificial restrictions to differentiate from the flagship SOC (845/865).

Did you get a volte carrier check disabled message after dialling that?
For me both volte and vowifi are working fine

Yes I got that. Are you telling the phone your real location or do I have to chose India or china? I remember with my Poco F1 I had to chose India to get features like call recording...btw I'm in Australia.

Changing regions
Anyone know if I do a factory reset and change to a different region like Europe will that make the phone operate on different Verizon bands possibly allowing me to get service? Just a thought ?

If you got the VoLTE was disabled message after entering the code, go to SIM settings and there will show the option to activate VoLTE. If not appears, try to enter the code again and check the SIM settings.

I think using different bands it's more about regional ROMs construction (Global, India, Europe etc) than changing region in ROM settings. Alternative, you can flash a different regional ROM using MiFlash and see if it helps with your problem.

After entering that code I get the switch, to turn on volte, but that doesn't change anything.

Can't you see the specific VoLTE symbol near mobile signal in the upper right corner of the screen? If you can't see it, you can try to make a phone call and see if the google dialer shows it's a VoLTE call (or check the dialer history calls if you use Xiaomi dialer....you'll see there if it was a VoLTE call or not).

Same here with my Poco x3 NFC global I am on Vodafone UK my carrier support volte and vofi but I can't enable it , I have no settings . What I found when I flash custom ROMs the volte works , the sound in voice calls is super crisp and I got the icon always there vote on sim and vofi on WiFi . I need an option or a menu or a trick to show that option in stock ROM to enable it .
I remember back in the days when I had OnePlus I had to go in the ingineer menu to tick on a toggle " enable volte" and "enable vofi"
And later on the OnePlus 7t pro I had to install an apk to force that toggle so I can enable it .

On my Mi Mix 2s it shows volte when enabled. This one no. Poco needs to fix this before a number of users get dumped for lack of volte.

Did you try activate it using this codes in Dialer? VoLTE: *#*#86583#*#* and VoWIFI: *#*#869434#*#*. After that go to your SIM settings and you'll get the option to activate VoLTE and VoWiFi.

I have tried those and I left it on enabled both of them . Still not working

If you have an locked bootloader I'm not aware about a method to flash another regional ROM. I had read that many Poco X3 users have problems getting mobile data connection with Verizon (especially in USA).

Hello anyone has managed to operate the volte on both sim cards simultaneously on his POCO X3? thank you

Got my bootloader unlocked I'll try flash another regional rom

Same here in Italy, no volte, it switch ti 3g. With my previous 8t all was fine

I am using the stock room and used the dial codes got the settings but everytime I tried to make a call it wouldn't work I went to setting all specs and tap internal storage 5 times then choose the sim you are using then you have to turn the top switch off then back on. This is how I got mine working I also have extended my storage by using root explorer and cut everything under sd card and move to storage.

Question Rog 5 Sim Card Problem

Hello everyone.
From months I have problems with one of mine SIM Card. Before the root and the FW update my Vodafone SIM card worked good (with also 5G). After the processes mentioned above it stop working.
Premise:
I’ve switched the SIM from slot 1 to slot 2 (don’t work)
I’ve cleaned the SIM card (don’t work)
On an iPhone the sim work perfectly.
It’s possible to solve this problem and rehabilitate the SIM? I really need it because the actual SIM some times lost the connection.

Uses the code in the dialer phone *#*#4636#*#* verify in information in menu (uper right) the bands, select your zone or automatic mode and ready
