I found out this week during the fire storms in southern California my unlocked SM-G930F doesn't receive any of these emergency messages. In fact, all references on how to turn them on/off lead you to either the Messages App or Settings of which the option to turn/off isn't there. Of course, the phone only a year old and bought through Amazon so that I can have an unlocked phone is not supported by Samsung. Oh what a surprise?
I didn't want to upload all new firmware, just an app that wil allow the option to turn them on/off or gate me to the feature. The assumption here is that Samsung makes bricks in the S7 variety that are designated by either the modulation hardware(cdma/gsm/tdma) and the firmware to support it. The rest would be just application??? Hence a GSM phone is a brick and the OS is specifically written for large carriers and or specific regions are transferred on pushes.
Is there anything out here that will enable the WEA on the phone?
I would assume WEA comes through the carrier, which means you'd need to flash the CSC for your carrier (assuming you haven't already). Since the G930F is an international model, if you bought it directly from Samsung and never added your own carrier settings to it, I don't think it would know to relay emergency messages.
There's a flashable zip with CSC's in the development section

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.

Hi everyone.
Last time i was in xda forums was when i try to mod my windows mobile CE 5.0 lol
This is my sad story:
I bought in the US a samsung s7 with T-Mobile SM-G930T, i paid a guy who 'unlocked' it in there. After that i brought it to Colombia, in here i run the T-mobile unlock app which succeded and erased itself after that. Then the cellphone started working with all the mobile companies in my country except for one that operates over 1800 mhz, other companies do work fine. When i insert a simcard of this company it just says that 'Not registered in network' and wont do nothing. I already tried to put the APN settings correctly (Actually it automatically loaded every company settings detected).
After that i tried to root with a modded Odin with a custom ROM and it succeeded and i got the SuperSU application, tho the cellphone its a little laggy now, but neither that way it worked. Anyone knows how where should i start looking?
I went to this company support and they sent me to Samsung support, which redirected me back to this company, lol
Thanks in advance guys

Hi,
It seems your phone is region locked due to which you are locked onto a particular mhz network frequency...
yes the first step would be to try to a custom rom to see if this over rides this situation or you could try below situation below... this is ideally for s6.... or atlast google search...
http://forum.xda-developers.com/verizon-galaxy-s6/general/enabling-using-servicemode-t3109579
Ok, since now we have root, many users wanted to know if they can lock onto certain LTE frequency bands using Samsung's ServiceMode. So here is a quick guide.
ServiceMode is Samsung's proprietary Engineering Mode, built within the TouchWiz framework, readily available on International variants, and some domestic like T-Mobile. It allows us to observe the RF connection, change certain RF related settings, and lock our phones onto specific technologies and frequencies. Sadly, Verizon has been blocking user access to Engineering Mode for years now.
So in order to enable access to ServiceMode on Verizon GS6/Edge you'll need to:
- Download Root Explorer
- Navigate to /efs/carrier/HiddenMenu
- Use TextEdit to open it (not text viewer)
- Change the value to ON (upper case), Save and Exit
- Restart the phone
Once restarted you can dial:
*#0011# to observe the connection
If you want to lock your device onto a specific LTE band (13, 4, 2):
*#27663368378#
- UE Settings & Info
- Settings
- Protocol
- NAS
- Network Control
- Band Selection
- LTE Band Selection
Here you can force your phone onto a specific Verizon LTE Band (13, 4, 2), or use LTE ALL if you have VoLTE (Advanced Calling) enabled as this will eliminate the need for CDMA radios.
To go back to default, go through the same process but at Band Selection make sure to chose AUTOMATIC.
There are a lot more settings here, you can enable AMR WB on UMTS if you use T-Mobile so you can get HD Voice on their UMTS layer, etc... Carrier Aggregation has already been enabled, so no need to tweak that.
If you aren't sure what certain settings and values correspond to, it's better to avoid tinkering. You're responsible for your own actions.
According to this thread, he posted via visitor.
Then he registered and posted his query here so he seems to have posted in correct section.
Just documenting this here.

My apologies if this is covered someplace; a search of the T-Mo S7 forums turned up nothing.
I am traveling internationally and that means the phone is always "roaming." I'm on T-Mobile's unlimited international plan and so the roaming is included. Nevertheless I get constant warnings about data roaming, by way of a popup. The popup offers a choice to go to roaming settings. If you turn roaming off, of course, nothing works, and then you still get a constant popup asking if you want to turn roaming back on.
I am not alone; the hue and cry has been raised about this over on T-Mobile's forums, here:
https://support.t-mobile.com/thread/141619
T-Mobile's response is that this is a Samsung issue and to take it up with them.
My phone is rooted stock and I have SQLite editor. Surely there must be someplace I can access the settings for this to turn these popups off altogether, but I have not found it. Or perhaps a service menu accessed by dialer code?
Any hints greatly appreciated.

My wife just called me from the UK with the exact same problem. She's using a brand new T-mobile S9+ running the latest update to oreo.
Reading the T-mobile thread I did see a couple of suggestions that had limited results. One was to disable the Samsung+ app or turn off all the apps inside of Samsung+. The other was to disable automatic network selection and to put it into manual mode. Problem with the second option is you have to reselect a different network if you are moving around...like most people do.
I'm going to call her tomorrow and see if any of these work. I'll report back.
Nothing worked. Fortunately, she brought her old iPhone along and started using it again. Sorry
If I have a Sprint-approved handset that has never been activated out of the box, and I flash a different firmware (say an unlocked global firmware) does Sprint already have the device ID in their database? Would I still be able to activate it via, say, online chat AFTER switching to the new firmware, or will something make the device "look" different to Sprint so it doesn't register as an approved device?
Forgive me if this has been covered but I havn't found the answer. I've flashed just about every phone I've ever had but my question here is can I / how do I flash to where the phone reads as XAA in download Mode?
The situation is my phone was originally on at&t. They unlocked it and I'm on Verizon. It all works great (it still says at&t on download Mode screen)
My problem is that if I log into the my Verizon app it disables my visual voicemail. I finally got a Verizon tech on the phone that explained that it is unsupported due to originally being on a different carrier and their system identifies that and disables the VVM. The only fix I can find is to put my sim in my backup S9+ that came from Samsung unlocked (or any Verizon phone) and I can then reactivate my VVM by resubscribing.
I currently have 3 Note 20 Ultras. One Each originally from Samsung, ATT and Verizon but the AT&T is the only one that is 512GB or I would just switch phones. I have flashed them all to U1 firmware but notice they all still reflect the original carrier in Download Mode so again my question is can I change this by flashing it / or is it just a matter of what sim card is in it when it's flashed? I need it to be seen as XAA by Verizon system so not to loose VVM... Pics attached.
Any advice here is greatly appreciated in advance.
Just a try... You can try the *#272*imei# method... But thats If it works. Not sure if the sims has to be in the phone for that to work.

Yes it brings up this menu... So I just select the XAA and that's it? I've been reading forums and this method is reversible it seems ... I'm familiar with Odin and all that but these hidden menus are new to me...
Thanks for the reply btw
You may have to activate the bottom most option to stay.
Don't worry if you can't access the menu after the change. You can download samsung band selection and change to automatic or one of the lte options then back to automatic to get to the menu.
CSC Guide
CSC (which I think means Carrier Service Code) helps to set what options for settings show in the device for things like voicemail and wifi calling, as well as sets network code information for things like carrier aggregation combos.
When you go to your phone settings->about phone->software information and look in the Service Provider SW ver. section, you will see as the last line a combo like XXX/YYY/ZZZ. This indicates what carrier sales and network code is set and what brand the phone was manufactured as.
I think of the XXX/YYY/ZZZ configuration as follows
XXX=Sales Code-What kind of features are setup in the firmware like wifi calling, video calling and settings menus
YYY=Network Code-What kind of network features are set for things like carrier aggregation and LTE/5G bands
ZZZ=Manufactured as Code- What model the phone was originally manufactured as. Ot has no affect on the system settings or options. THIS CAN NOT CHANGE. IT SHOULD ALWAYS BE THE SAME. ONLY A ROOTED PHONE WOULD BE ABLE TO ACCESS THE FILES NECESSARY TO CHANGE THIS.
for more details, refer to post:-
