Help with enabling hidden menus/Force LTE Mode Galaxy S6 G920T - T-Mobile Samsung Galaxy S6

Model SM-G920TXAR3COK1
Android Version 5.1.1
I have been trying to activate the hidden menus on this device with the ultimate goal of using the menus to force LTE only. I have rooted the phone using the latest version of Odin (I believe 3.10.6 or 3.10.7). I have tried multiple third party apps and I have tried side loading different apk's through adb, but nothing seems to work for me. I haven't been able to find any threads about my situation that could point me in the right direction and would appreciate any help!

That is a cellular south firmware, so is that your carrier? If it is, continue reading, if not you should probably flash the tmobile rom.
What happens when you dial *#0011# ?
And then try *#2263#
If neither of these work it's likely that the hidden menu access is removed from your firmware version by the carrier and there is no way to change that that doesn't involve flashing new firmware. If the phone is carrier unlocked you could flash tmobile firmware on it since it uses the same phone model. Tmobile has hidden menus enabled. You should of course research the risks of doing so and whether that would stop you from using certain carrier features. [I know nothing about Cellular south.]

When I dial *#0011#, I get the ServiceMode menu. Is there more settings to this?
When I dial *#2263#, nothing seems to happen.

2263 is the section of service mode that allows you to specify band selection.

It seems it's removed from your firmware.

I flashed the phone with the T Mobile firmware and I am able to access both codes. However, I am not able to get to the part in the service menu (*#0011#) in which I can select an LTE only mode. The menu doesn't seem to respond to any key inputs. Currently, the phone is unrooted with a firmware of G920TUVS3DOJC. Does it have to be rooted again in order to be able to access that part of the menu? Or is there a different way?

Ah it seems I misunderstood your question a bit. I thought you wanted to force a specific lte band, which 2263 can do. 0011 is not an interactive menu, it's just a status screen. I don't know of any way to force it to LTE so that it never drops off to other mobile technologies.
Edit: If you go to 2263, under band disable settings, select WCDMA [this is I believe what samsung calls HSPA for some reason]. You'll see this: https://puu.sh/nDjIp/d95be8b0a1.jpg
Tap each band there once and the [*] will appear which means it's disabled. Disabling them all should in effect disable HSPA. Hope that helps. Almost positive there's no way to disable things like edge or gprs though.

[Q] *#*# codes

Hey everyone,
Does any one know how to get codes like *#*#4636#*#* to work?
Id like to poke around within the network settings and also check out the wifi signal strength.
When i try the code above nothing happens. However the thunderbolt 4g switcher app in the market allows me to bring up the radio menu
I'm not sure this has everything you're looking for, but try ##PROGRAM
UseAnyCut from the market to set a shortcut to any of the hidden menus, no keycodes needed.
##program still 000000
##program password is still 000000

Thanks i dident know this phone had the ##program code still in it. That will work fine
##PROGRAM is for the CDMA radio programming.
Anyone tried *#*#4636#*#* code (this is Android's networking test/settings menu). I wonder if there is way to switch phone to GSM mode
Hi leo like I said above, you can get to all the menus easily with shortcuts but GSM mode is disabled in the radio so that won't work.
All of the low level settings menus are available though.
Thanks CZ, I miss the good old days when TBH was overflowing with moto leaks.. I'd imagine uncrippled radio

Oh how I miss those days too...waiting for the full xml.zip for the D4 so we can have some fun with it safely is killing me!
I expect there to be an update that unlocks the GSM global roaming capability soon,we'll see.
GSM requires more than a simple "unlock" - Motorola makes multiple different sets of radio firmware for this hardware. The GSM firmware is completely separate and totally absent from our radio image.
Can the gsm firmware be added somehow? It is the only way I'll ever be able to use this phone with my provider.
And it's not like I have any other good options for dual core sliders...
Sent from my DROID2 GLOBAL using XDA
Droid 3 is a dual core slider with full GSM global capability and will be much easier to get working anywhere you might be than the D4.
There are rumors about GSM being enabled in the firmware with an update, but the radios are signed images and virtually impossible to write your own or even a modified image.

[Q] *#*#4636#*#* settings

Hi All,
I've been messing around with my phone and accessed the *#*#4636#*#* settings thru the dialer. Any one know what the following does?
Testing-->Phone Information
Scroll about half way down there's a popup menu that lets you select a whole bunch of different network types. ie WCDMA, GSM, CDMA, etc.
Does this mean if I take my Sprint phone to Europe or Asian I could use their networks without flashing a new radio?
Thanks,
Ken
This code is used for accessing Service menu of your device.
And you cant use different networks without flashing radio
Even flashing a new radio wont get you new frequencies it seems...

What the network type selection allows you to do it turn off network grades (ie, 2G/3G/LTE)
For example, I turned off my LTE as I don't need that speed and the coverage is spotty. So, in doing so I end up saving battery life bc my phone will only search for 2G/3G networks and wont flip btwn 3G and LTE all the time.
If you want to use your phone on a different carrier in a different country, you'll need to have your SIM unlocked and possibly have flashed the radios required. This should be all there is too it, but I could be wrong.
As it is, if your phone is not the dev. version, your phone will be locked to Sprint, so your phone will not connect to networks that are not Sprint.
Please help I'm in same situation and have no service issue after messing with that setting menu, i have mobilink jazz sim card and xt1526 sprint

[HOW TO][R&D] : SM-G900P working with any LTE band.

Hi everyone,
I really appreciate the work everyone puts in on this site, it's amazing. This past week, I bought a Samsung Galaxy S5 (SM-G00P, the Sprint Model)
So I will edit this guide later on with pictures, but right now I just need to write down what I've discovered.
I'm also not sure if everything I say is necessary / absolutely will work for you, also if you try to do some of this on your own, it's your own responsibility if something bad happens.
--------------------------
Short Requirements
--------------------------
EFS Professional
QXDM Professional (I believe QPST must also be installed)
Cyanogenmod 12.1 with BusyBox
So, what I have done is flash Cyanogenmod 12.1 for the SM-G900P on the phone and installed BusyBox. Then I have downloaded EFS Professional on my computer.
Then enable USB Debugging (adb debugging.) Open up EFS Professional, go to the Samsung Tools tab and select the bottom option with includes Modem + Diag. Open up QXDM Professional, go to the Communications tab up top and enter in the Samsung port (COM9, for example) and make sure to check it off.
Go to "LTE" option in QXDM and enter in "0xFFFFFFF3FFF" AKA "17592185995263" underneath ID 06828 and ID 06829. There should be two config's per ID, I entered in both. (It should be noted that "0xFFFFFFF3FFF" will enable "ALL" LTE bands and may not be necessary)
----------------------------------------------------------------
Finicky Step (That seems to enable LTE, somehow)
----------------------------------------------------------------
Now restart the phone, just to eliminate any possibility of errors. Go to: Settings > Mobile networks > Network operators > choose AT&T
Now I have done this step differently a few times, but this is what seems to get rid of HSPA+ and H to force LTE on (not sure why)
Sometimes I have selected T-Mobile instead of AT&T and let it time out, then select AT&T or just restart the phone and select AT&T.
I really don't seem to understand why this works like this, maybe someone has some more insight? If I restart the phone, it goes back to HSPA+.
I know this is using AT&T's LTE bands, because LTE Discovery shows Band 2 a lot of the time. Weird thing is, sometimes it shows Band 25, even though I believe that is a band that Sprint uses.
CM13 - Does not have "Network operators" option.
I'd like to write a script that either automatically goes through the menus on boot, or can automatically disconnect from the network and connect to the correct network.
ALSO WORKS,
If you download the "Radio Switcher" app, set to GSM auto (PRL), then set to LTE/GSM auto (PRL) in that order.
Turn OFF radio, turn radio on, select GSM auto (PRL), let it connect, then select LTE/GSM auto (PRL) and it will connect to LTE immediately.
Mostly interested in the underlying causes of why this works. Could be applied to more phones in general.
Earlier when I was adding LTE bands it seemed like they added (showed up on QXDM) but LTE would never connect. Something interesting is in the program "DFS" 6829 wouldn't show the edited changes or let me edit them, QXDM seemed to work ok though.
Other discoveries:
Once you initially set it to LTE, sometimes it randomly goes back to HSPA+. But I've had LTE last good amounts of time (1-2 hours)
If you make a phone call it switches to HSPA+ but won't revert back to LTE.
If you open up the "Radio Switcher" or "Network" app (they are the same) it sometimes will just go back to LTE immediately, other times you simply need to run the Ping test.
I think it keeps reverting back to HSPA+ after a while because it eventually connects to Band 25. Not sure if I can access the Service Menu (*#0011#) on Cyanogenmod, maybe to set priority? Might actually be because of too many different LTE bands enabled.
I'll try adding only AT&T's bands to see how things work.
So far, tried bands 2, 4, 5, 12, 17 - can't get LTE. Band 2 only, can't get LTE. Only getting HSPA+ on GSM auto (prl) and HSPA on LTE/GSM auto (prl). Tried both decimal and hex values in QXDM. For example, I've entered in 2 (decimal) and (0x2) and (0x02)
Wanted to point out here, phone booted up with service immediately.
Tried all bands except for 25, no LTE, a little more laggy, but not as bad as when band 25 is enabled.
Tried band 2 and 25, Got LTE, takes a lot of time when turning on phone for service to appear and when changing radios.
So, for some reason band 25 is needed in order to get LTE on other bands.
With bands 2 and 25 only enabled for LTE, I rarely drop to HSPA+.
It has only happened twice in the past 6 hours. (The LTE Discovery App has an option to cycle the network when LTE disconnects, which seems to only refresh HSPA+ once it goes back)
---------------------------------------
So I went back to stock firmware on the Touchwiz 5.0.
"Network" and "Radio Switcher" apps don't work, but "Advanced Signal Status" does.
Same steps work here as above in "getting" LTE, also there are more options to choose from.
LTE/WCDMA seems to work too.
Problem is I am getting this error:
"LTE: ESM - 33 EMM - x"
and can't connect to the internet, only band 25 seems to be connecting, unlike band 2 last time (maybe this is because I was on klte CM ROM).
I also should note that it now says "GPRS service: Disconnected"
In ServiceMode (*#0011#) I haven't had any luck, in the cases where I can do anything with the LTE bands it is only for 25, 26, and 41. Other cases show more bands, but it says something like "not
supported" to edit anything.
I also tried messing around with the ##3282# LTE settings, only shows 25, 26, 41 bands and I can't change the priorities.

This is because Straight talk doesn't support Voice over 4G, so your data connection has to fall back to 3.5G in order for a call to be placed.
Some more observations, I used this app called connection stabilizer which constantly pings for network connectivity. I think this might help keep the LTE up longer, when driving I will eventually lose LTE and get a ping failed. I'm not really that sure if this helps or not, but it's a total pain because you need to keep data on. One more thing to note is on the "mobile network settings" page I never see "GSM/WCDMA/LTE" option
I believe the only way for a permanent solution is to be able to flash another modem on the phone (such as SM-G900A or SM-G900T). Problem is Odin will never let me, I've tried everything to get another modem flashed with no luck, if anyone has any ideas or solutions please let me know I'd love to get this phone working consistently with LTE, although it seems that I may as well just return it and get the SM-G900T as it supports many bands (including the AT&T bands) Only thing is there is no FM Radio on the T-Mobile version, but I was planning on using Cyanogenmod anyways and NextRadio doesn't seem to work with the SM-G900P with Cyanogemod. Maybe there's a build.prop edit to allow it? Or maybe it's a kernel issue.
Did you make any further progress with LTE on touchwiz? Been tinkering and trying to get T-Mobile LTE (band 2 & 700Mhz) working on my own G900P.
Something interesting I found is that if I have it set to LTE/GSM (autoPRL) sometimes it will remove (hide) any T-mobile APNs and force you to use "sprint wholesales" and "global roaming SPCS". (switching back to GSM/WCDMA restores the T-mobile APNs. I wonder if that can be overriden by finding where those defaults are in the system files and editing them to be T-mobile...
Since the G900P is a CDMA phone, I've assumed that to get LTE on a GSM network I'd have to edit NV values in QPST/QXDM/EFS Professional to enable some bands. I've done that before on a G900V with KitKat on it and it gets GSM LTE fine.
The past few days I've looked for a solution and yesterday I was finally able to seemingly enable diagnostic mode and get into my G900P that has Marshmallow 6.0.1 on it. It was a headache just getting in to read the values. QXDM read the NV values but they only went as high as 6754; in the past the LTE bands needed enabling on 6828 and 6829. I don't know if the NV system has changed in Marshmallow or if my versions of QPST/QXDM/EFS Professional are outdated and won't read everything in 6.0.1 or some other problem. I wasn't able to make any band changes. Maybe somebody with more experience will have better luck.

In my case... I've managed to get it to look like the bands in question are enabled via QPST/QXDM (confirmed with readback through DFS/EFS pro)... but the LTE radio still doesn't activate (band ID in the debug screen is -119, LTE radio is "idle")
the write "block" you're experiencing is something Qualcomm/Samsung put in the android code as a binary blob (no source for people to find and disable/reverse engineer/bypass). Third party mods (CM etc that are not touchwiz kernel based) don't have this block.
I think I'm SOL with my only remaining option to try flashing a custom ROM. The LTE radio in my device simply won't start on any band other than 25.

Sorry for the late reply, I basically gave up after not getting anywhere with hours spent on this, I tried flashing alternative modems and nothing would work.
So this is what happened to me. It would show it alternating between bands 2/25.
My theory is even though I was able to modify the bands on the device (the values registered) it didn't do anything.
It seems as if disabling bands is the only thing that really works.
CM13 (kltedv) seemed to run as an okay ROM for the Sprint S5, it was easier to force the 2/25 LTE band on, problem with this is when you disconnect from that tower or place a phone call it will revert back, plus there comes to be issues with texting/calling by forcing it on LTE and there seems to be issues with switching between LTE and HSPA+
I recommend purchasing a SM-G900T as it provides a multitude of bands and the bootloader is unlocked, only downside is the FM Radio does not work.
*If anyone gets other LTE bands working on this phone, PLEASE post the solution here it would be insanely appreciated*
Yeah... there was some discussion as to whether the 900P doesn't have band calibrations for non-sprint LTE bands.
I'm not really looking for a new phone, just figured that if I could get LTE it would be a nice bonus.
Re FM radio: I looked into this some a while back, it works on the G900P because they have the correct radio transport code in the radio app... (other radio apps can't see the FM chipset) there are actually kernel modules (iris_radio_transport.ko) which should provide a standard FM radio interface for the G900P. Be interesting to compile those for a non-sprint phone and see if other models also have FM radio.
Well this thread kind of got my hopes up, then back down again.
I would really like to be able use LTE with this phone for AT&T. Having a difficult time trying to get it to read with QPST. EFSpro works fine though.

Hi, in the NV browser there should be a tab that has a pull down menu where you can just jump ahead and get to 6928/6929.
Out of curiosity, what baseband firmware are you on?

I'm on CM13, I'm sorry I just realize that I'm on a different firmware than the one in the tutorial.
If you mind, let me please take a little time to explain my case.
The phone had several problem (you can ask details if you want) I went to my network provider to see if they can fix it, the representative told me the phone needed to be flashed but since I didn't bought it from them they could do nothing. And when I got back I searched Google to see what it is about.
I could see under setting that my phone was a SM-G900T. Than I downloaded the stock OS for that specific version of the Samsung Galaxy S5. And any other required stuff like Odin, Samsung USB drivers and more. But the freshly downloaded firmware failed to installed on the phone. I finally managed to understand when I saw in the download mode screen that the phone was a SM-G900P NOT SM-G900T.
Than I downloaded the stock firmware for SM-G900P and it success to install on the phone. The phone was then working perfectly fine. But I couldn't get LTE since my carrier's band for LTE is band 3 (1800). And I tough if it had SM-G900T previously and at this time it was compatible with my carrier's LTE band cause T-Mobile also has band 3 for LTE, that's suppose to mean that I can get SM-G900T aboard or to have band 3 on it.
Maybe I give too much detail, but I want to make sure you fully understand the case and thank you for your help. We're almost at the end (loll).
Based on my reading, I tough installing a custom firmware would resolved the problem and that's why I installed CM13 (the first time I could say I love android ... I'm more accustomed to iOS) to find that I was not that right (it get even worse cause now I receive no data at all unless I'm on WiFi). Than I found this tutorial and an other one on XDA saying that it's possible to enable other bands on the phone.
But any tuto I use I get stocked at some point and I'm so novice to that field. But I can follow institutions:good:
Actually I can't access the USB settings screen and there's only two codes that works on it : *#06# for imei and *#*#4636#*#* which open a screen named "test".
I wish I gave useful details on the case, if there's anything else you need to know fell free to ask.

And when I got back I searched Google to see what it is about.
I could see under setting that my phone was a SM-G900T. Than I downloaded the stock OS for that specific version of the Samsung Galaxy S5. And any other required stuff like Odin, Samsung USB drivers and more. But the freshly downloaded firmware failed to installed on the phone. I finally managed to understand when I saw in the download mode screen that the phone was a SM-G900P NOT SM-G900T.
Than I downloaded the stock firmware for SM-G900P and it success to install on the phone. The phone was then working perfectly fine. But I couldn't get LTE since my carrier's band for LTE is band 3 (1800). And I tough if it had SM-G900T previously and at this time it was compatible with my carrier's LTE band cause T-Mobile also has band 3 for LTE, that's suppose to mean that I can get SM-G900T aboard or to have band 3 on it.
Maybe I give too much detail, but I want to make sure you fully understand the case and thank you for your help. We're almost at the end (loll).
Based on my reading, I tough installing a custom firmware would resolved the problem and that's why I installed CM13 (the first time I could say I love android ... I'm more accustomed to iOS) to find that I was not that right (it get even worse cause now I receive no data at all unless I'm on WiFi). Than I found this tutorial and an other one on XDA saying that it's possible to enable other bands on the phone.
But any tuto I use I get stocked at some point and I'm so novice to that field. But I can follow institutions:good:
Actually I can't access the USB settings screen and there's only two codes that works on it : *#06# for imei and *#*#4636#*#* which open a screen named "test".
I wish I gave useful details on the case, if there's anything else you need to know fell free to ask.

But beware, I'm not sure if this works. I have countless of times tried to do this mod and successfully completed the LTE mod, I still don't get LTE. No matter what radio I set it on. I even flashed back to my stock firmware, rerooted, and tried again to see if I could have more capabilities in service mode. It appears that you can only enable/disable the LTE bands that are equipped to the hardware.
Meaning that my LTE Modem most likely can only use band 25,26,41 as it's the only bands to be coded in my modem firmware. However, I was able to unlock band class 10, because it was built with the hardware.

Whoa easy there, my 6928/6929's description is LTE BC CONFIG
LTE BC CONFIG DIV.
In the NV browser, there should be pulldown menu, within that menu, there should be an LTE category. Where LTE BC CONFIG/LTE DIV (6928/6929) should be. If you can't find it then I can may no longer be of assistance as the efs may be different considering the differences you mentioned about firmware earlier.

Use your Sprint phone on T-Mobile.....ZV6 users only?

This is not mine, I take no credit, Mayrer has done most of the hard work for us, you credit him for his work and everyone he has worked on to get your Sprint to working for GSM.
http://forum.xda-developers.com/spri...nlock-t3229801
I have only updated the information for changing in hidden menu and PropEditor. I also credit the maker for the CDMA to GSM Patch, Mentor.37 for his work and everyone else who has helped him.
http://forum.xda-developers.com/showthread.php?t=2394689
I do not know if this will work for any other Sprint phone not on ZV6
Bands 2, 4, 12 are for bands T-Mobile.
Download PropEditor and edit these settings....Don't forget this step first!!
ro.build.target_operator=SPR => TMO
ro.build.target_country=US
ro.telephony.default_network => 9
telephony.lteOnCdmaDevice => 0 ....don't forget to save and reboot.
Along with Hidden Menu 5689#*991# to change your APN settings properly and set
Field Test => Modem Settings =>
PDP Setting => [5] APN Setting ...... now you have to select the bottom one then go into menu [ ] press until you see delete APN
you must do this because a bug I am seeing only allows the bottom APN setting to be used, I usually delete all until the APN I use is on the very bottom selection. no go back
Network Mode = Automatic => go back => RAT Selection = GSM/WCDMA/LTE auto
LTE Band Selection doesn't work proplerly so installing the modded Shortcut Master (Lite) from the link above be sure to go to
lotHiddenMenuMain (witout root) => LTE setting=> LTE Data Roam Config....and enable
Bar Roam Forced
Bar Roam Enabled
Roam Guard Forced
Roam Guard Enabled
Band 2
Band 4
Band 12 go back
Band 25 should be disabled unless you can use it. You cannot really set APN here.
I sometimes install the CDMA to GSM patch for global phones but I then have to re-do the PropEditor settings again, but it may be able to configure anything else that is missing, you can try to Adb Sideload the zip or use FlashGordon app to try to install, honestly I don't know if either worked for me for the patch.
This is what I configure to get my phone to working with T-Mobile.
I only submit this, I cannot provide support, you can always add on to anything else I may have missed or messed up, thank you.
Has anybody with an LG G4 rom version ZVG been able to successfully get their phone working on T-Mobile?
My phone is paid off and Sprint sent the domestic SIM unlock code. When the TMO sim is in and the phone's network mode is set to Auto, and and APN is manually entered per TMobile's specs, the phone can connect to the network and make calls, send SMS, connect to EDGE data, and sometimes send MMS, but it never connects to LTE. If I change the network mode to LTE/CDMA, the phone doesn't connect at all.
I read elsewhere to try change the "Bearer" field in the APN to "LTE" but that field is not displayed or editable in the APN input/edit screen. I tried a bunch of the Shortcut Master (Lite) or similar ways to expose the hidden menus to edit the full APN but they all fail due to permissions (because of ZVG version?). Shortcut Master (Lite) says it would work if upgraded to the paid Secret Codes version, can anybody verify that before I pay?
Or, any other suggestions to get this fully working with LTE or can even confirm that this is possible?
guys this is kinda old news
the build prop also is better set from
ro.build.target_operator=SPR => OPEN
then xposed modules such as android theme and such work.
but great find on thew band settings
ive been running my g2 g3 and g4 on tmobile and att and its subsidiaries for a long times now
and the g series sprint phones have been the best at taking to other networks due to the sprints already supporting most of the bands`
---------- Post added at 08:43 AM ---------- Previous post was at 08:43 AM ----------
request for modderators to move this thread to the general area
i also thin the mellow mallow international roms go up to zvb which should work on tmobile and i can verify att networks
Doesn't the phone need to be rooted for the build prop to be edited?
And as far as I can tell, there isn't a root for a G4 on ZVG firmware?
Basically, to start with, can anybody confirm if a LS991 ZVG can be made to work on TMobile without root, or if there is a good rooting method, where is it?
Thanks.

Can you be more specific on what I need to ask Sprint about? Like I said, I asked for the the Domestic Sim Unlock and they sent that over the air and a confirmation showed up on the phone. It does not reject the T-Mobile SIM like it would normally, so something has changed from the default state.
Still looking for confirmation from somebody that has successfully connected their ZVG LS991 to TMO after a Domestic Sim Unlock.

so its accerpting the sim but apns are still greyed out where u cant edit them
need to ask sprint for the msl of this device so u can attempt to edit the apns it may take a few calls but most of the time if u keep ure cool and keep trying they will eventually give it to you
tell them the situation u paid it off they sent u the unlock code but are still unable to edit the apn without the msl

at&t mobile network options

Anyone have the lg v40 running on at&t? surprisingly i have no options under mobile networking. I can only enable international data roaming and setup new apn. Usually i'd expect to see settings allowing me to change the bands.

Everything is auto- , the phone I have is locked to att and I guess the only way to change that is to unlock the phone.

It bounces off 2 things, the phone's props and the network being detected. Using the unlocked does not enable settings if it's not natively supported by the carrier contrary to popular belief. That was true on older versions of android. Newer ones relies on multiple configs to decide what options you get to see or not. In most cases, if the phone model is not what is expected for a particular network, it will default to global roaming mode that has the least set of options. From what I've seen, this comes as a result of carriers requesting to have specifically designated models tailored to their service.
If you are rooted, you can tweak stuff in build.prop to have the phone switch carrier and regional modes.

root not needed:
1. for network mode, try dial *#*#4636#*#* and then phone information, this works on my v35 with tmo and att sim, you can also use a 3rd app called "network mode" which is a shortcut of the above, hope that works on v40 too.
2. for band selection, I use 277634#*# on v30(tmo unlocked) for both tmo and att sim; I use 277634#*# on v35 (both att unlock and usa unlock) for tmo sim; I use *#546368#*350# (need to dig into the menu to find band selection) on v35 (both att unlock and usa unlock) for att sim; hope either one of these two works for v40.
