[Q] Ghanging BandMode - Galaxy S III Mini Q&A, Help & Troubleshooting

Hi, guys. I installed OmniROM 5.1.1. There is no normal engineer mode on our phones. How we can change bandmode of GSM? Of cause, there are EuroBand, USABand and etc... But some frequencies don't work in my region, for example. What're we be able to do in this case?

@by_rofl_alex
If your phone is destined for your country region than why you asking about this? Device should automatically scanning for gsm band which is supported by your operator and connect to closer signal tower. In hidden menu (on stock firmware) MAYBE you was able to select frequencies per band, like 850/900/1900/2100 but phone normally do this automatically after modem starting (booting phone or turning off airplane mode).
Look here if you're advanced user, maybe you find something http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
Edit: I attached application from I9100 CM (of course full credit for team CM) which working on Ace 2 LP ROM, so should working on S3 Mini as well.
Try install as normal app or push to system/app chmod 644, reboot phone.
How to use?
In dialer type:
*#*#197328640#*#*
Go to DEBUG SCREEN > PHONE CONTROL > NETWORK CONTROL > BAND SELECTION > AUTOMATIC (scan all available frequencies) or choose one from WCDMA BAND (900/1800/2100) or GSM BAND (850/900/1800/1900).
Don't know if change's are saved after reboot.

Phone Band Settings

Is there any way to configure the UMTS Band settings on the Trinity / D810? I ask as the ROM provides the following options:
Network Type:
Auto
GSM
WCDMA
GSM/UMTS Band:
Auto
GSM(900+1800)+UMTS(2100)
GSM(1900+850)+UMTS(1900+850)
UMTS(2100+800)
Now ... for the HSDPA Network in Australia for Telstra (Next G), I need the phone to work on the UMTS(850) Band. However, by selecting the option above where the only UMTS(850) is available means that the alternate 3G Band (not HSDPA) of UMTS(2100) is not available, and the GSM Bands in the same selection are not valid for the Australian market.
Couple of queries, and I hope there are ways of configuring the device to achieve this (without getting a new ROM to support it):
When a Band selection is made, what is the order which the device uses the connections? ... i.e. if the selection was GSM(1900+850)+UMTS(1900+850), will it look for UMTS or GSM first? If UMTS, which band - 1900 or 850?
When Auto is selected, I am guessing it uses each option in the list until it finds a valid network? This would mean that for Australia, if left on Auto, you would never select HSDPA for Telstra as it would find the 3G UMTS(2100) network first (non-HSDPA).
My assumptions are that if left on Auto, it looks based on list order (which is the network order in the registry). So, for Australia, I need a setting like the following:
GSM(900+1800)+UMTS(850+2100)
Is it possible to create this Band Selection without a new ROM?

The new Dopod ROM has the same band selections as yours does. I tried changing the selections to manual with bad results. I just leave it on auto now.

I could do that to, but it would mean I don't get HSDPA. I have verified this. The only way to get HSDPA is to set the Band selection to the one with UMTS(850) in it ... this is not ideal, and that's why I posed the question to this forum.
No one??
I am guessing that no one has ever come across this, or needed to do it?
Registry Patch
This Registry patch works for the Hermes. It might work on the Trinity.
[HKEY_LOCAL_MACHINE\SOFTWARE\OEM\PhoneSetting\BandType]
"ItemCount"=dword:00000006
"ItemName1"="Auto"
"ItemName2"="GSM(900+1800)+UMTS(2100)"
"ItemName3"="GSM(1900+850)+UMTS(1900+850)"
"ItemName4"="UMTS(2100+800)"
"ItemName5"="GSM(900+1800)+UMTS(2100+850)"
"ItemName6"="GSM(900+1800)+UMTS(850)"
"ItemValue1"=dword:00000000
"ItemValue2"=dword:00000001
"ItemValue3"=dword:00000002
"ItemValue4"=dword:00000003
"ItemValue5"=dword:00000004
"ItemValue6"=dword:00000005
[HKEY_LOCAL_MACHINE\SOFTWARE\OEM\UMTS\BandSelection]
"Band"=dword:00000005
You really just need to add ItemName5 and 6, and ItemValue5 and 6, and change the ItemCount from 4 to 6 (as you added two options) using your favorite Registry Editor.
Do a soft reboot of the phone. Now you can select the NextG option GSM(900+1800)+UMTS(850)
3G connection
I drive around the Perth Metro area a lot for work and am finding that if left on Auto the connection is lost quite often mid call. How have you found the 810's management of the bands? And the auto fallback? Is there a way to set the fallback threshold so it drops back if under 2 bar signal strength? At the moment it sits on 1 bar strength and drops out mid call.

Switch from 2G to 3G

Recently bought a Samsung I897 Captivate. Its a unlocked phone and I'm using it in Argentina with Movistar. My previous phone was a Motorola Milestone, and it sometimes changed the connection from 3G / HSDPA to 2G (EDGE), in 3G areas. The solution was to go to APN settings, enable "2G only", then disabling it, and the phone instantly switched to 3G again.
However, the Captivate doesn't have such option. Setting the phone to Flight Mode its useless, it will keep connecting in 2G.
Only solution I found at the moment was to go to Network Mode (*#0011#) then navigate to Network Control => Band Selection, selecting WCDMA only, and then enabling Automatic again.
That seems to reset the connection.
I searched in the market for free and paid apps to help me fix this issue, but I found nothing, only the Toggle 2G app, but it only works with Cyanogen Mod.
I have some questions:
If I set the connection to WCDMA only, then I'll have no signal at all in 2G areas, right?.
Does anyone know a quicker way to do this?. I tried to make a shortcut to ServiceMode with dg Quickcut but when I try to open it it crashed the phone.
Thanks in advance.

as of right now, there is no "fix" for this. the best you COULD do is to flash Eugene's VibrantHybrid ROM where the "use 2g networks only" option does exist, but you'll lose GPS (for now)

Thanks for the quick reply Kaik541.
Does the signal strength improve with that rom?.
Currently I'm using I897UCJH7 from samfirmware.

you should revert back to JH3 if you're going to use Hybrid (I don't believe JH7 is compatible yet, there are some issues that cropped up with SRE, so it would be safer to do JH3, or even better JF6). I've seen slightly better reception and MUCH better battery life running Hybrid

It seems it will be updated soon.
Maybe I'll give it a try.
Do you know if it removes the 850 band?.
I need it, because my carrier uses it for WCDMA.
Try this:
1. In the Market, download Any Cut. (This is a free app) 2. open Any Cut and choose New Shortcut 3. select Activity 4. Scroll down the list until you get to Phone Info 5. Select OK. (this will place the short cut on your homescreen) 6. Open the shortcut and scroll down until you see "Set Preferred Network Type" 7. Choose GSM only and you are set. This forces the phone to EGDE
I used this to force edge. Use google to download AnyCut, it doesn't exist on the market for the unknown reason
Sent from my SAMSUNG-SGH-I897 using XDA App
I just discovered Juice Defender. One of its features is to set phone to 2G automatically (seems very configurable). I haven't really had a chance to test it, but thought I'd mention it to you anyway

Thanks a lot. I use dg Quickcut for that.
But, I don't need to force EDGE, I need a way to force 3G .
The phone usually switchs to EDGE in 3G areas, and I need to change it back to 3G.
I've used your suggestion to make such shortcut, changed it to WCDMA only, clicked the Disable Radio button twice (because it didn't changed to 3G), and when it switched back to 3G, I changed back the network to GSM / CDMA auto.
What about WCDMA preferred?. Will it try to allways connect to 3G?.
can yall not just dial * # * # 4636 #*#* scroll to the bottom and chnage it there, just so happens i posted a how to earlier in the general section, works on stock ROMS afaik.
also GPS still works

[Q] Anyone knows how to change HSPA / HSDPA to enable? PLEASE HELP!

hi... my name is Juan and I'm looking for help from chile...
I want to enable HSPA / HSDPA in my samsung galaxy S, because here is very slow our mobile network.
Me and my girlfriend we have the same cellphones, our configs are the same (options, mobile company, acces point names, everything!)
She can "surf" with HSDPA at 1.9mb/s but my phone is always in EDGE and everytime that I make a test with SpeedTest, my speed is 0.07Mb/s!!!!!
I read EVERY PAGE, in the thread: http://forum.xda-developers.com/showthread.php?t=837716
and I was looking more for help here...
I sought on internet and I tried EVERYTHING... but nothing happen...
Please, exist another way to change the HSPA / HSDPA from 0 (disable) to 1 (enable)???
please, help!
thank you!
no one?
any idea? change a variable inside the root folder??? please help.
thanks!
First do you have 3g enabled from your operator?
Secondly make sure your network is not set to gsm only in your handset
Im having this problem also.
Trying to flash CM7 and having issues. I believe the answer is to enable HSDPA.
Has anyone managed to successfully get this working. Im on Orange UK if that helps.
Did you followed this procedure:
Go to the phone dialer pad and enter this code: *#301279#
Click [2] CHANGE HSPA REVISION
Click [1] RELEASE 99 (HSPA OFF)
Then you should see something like:
CHANGE_R99
HSDPA OFF, HSUPA OFF
?
I've exactly the same issue. I have tried the *#301279# code and change it to on, but it just won't. I'm going into "Click [2] CHANGE HSPA REVISION" and selecting the HSDPA to on. But if I go back and check the status it is still 0. Is this has something to do with the carrier? Or maybe after selecting the value you need to save something? Desperate!
I have the same problem. I have hsdpa 0 hsupa 0 and can't turn it on anybody has solution ? I wanted flash cm7 but I can't do it without hspa enabled
Yup same issue here. Was going to create a new thread, but perhaps I should bump this one instead.
*#301279 is permanently ingrained in my head now, but I just can't seem to modify any settings through it.
Suggestions if anyone new has come on board?
if you are all running CM7 I think you need to flash to a 2.2 rom, enable HSPA in that rom and then flash back to CM7. I read that somewhere in the tutorials for previous versions and not sure if this bug still exists but just so you know. good luck

Enable 3g from your operator. Then go to settings > wireless and network > mobile networks > [select] use packet data, set network mode to WCDMA/HSDPA/UMTS.
Should work now.
I have the same problem..
but when i go to settings > wireless and network > mobile networks > [select] use packet data, set network mode to DSM/WCDMA (auto mode)
Where is HSDPA & UMTS ?
anyone can help..
This worked for me.
1. dial *#301279#
2. select 2
3. select 3
4. hit back key to exit.
5. go to Settings->Wireless Networks->Mobile Networks>Network
Mode. Select GSM/WCDMA(Auto Mode) or option 1 whatever that is.
6. hit back key to exit.
7. If still not working toggle airplane mode. This step should not be needed though. If you wait a few seconds you should see the 3g/h/h+ appear.

[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.

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.

Also I got the values for 6828/6929 to stick. They are there when I reboot and everything. My biggest issue now is forcing LTE. I'm on CM13 and I have tried the prl method you mentioned but no matter what I try, LTE won't activate.

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)
Hi! Thank you so much for the hard work. I've try to follow this tutorial but I'm stock somewhere. I'd really appreciate if you could help me. I don't see "LTE" option in QXDM. I managed to get in some places where I can see LTE but I don't see where I can edit anything to enter in "OxFFFFFFF3FFF" AKA "17592185995263”

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.

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.

Note 8 (SM-N950F) Lock network BAND

Hi guys,
I have rooted my note 8 with deluxe ROM to access hidden network setting option to lock specific band of network. As we know that, Hidden network setting option is disabled by Samsung but, I rooted my device and download apk of hidden network setting and placed in system with help of root explorer. Everything went perfect. Now, I can access section where i can select specific band and lock it. I access it with Shortcut Master Lite. But, When i tick on specific band and toggle the selection button then it shows message success. Immediately my network change to my selected band. I can check from *#0011#. But, if my phone remain in stable state for few seconds then it automatically switch to another band. Which mean it didn't lock to specific Band. When i go back to hidden network setting, there is no tick on my selected BAND but toggle but still says that i am on selected band option instead of LTE ALL. I am using India Jio Sim card which support Band 3, 5 and 40. I get very good internet speed on 3 and 5. But, It automatically switch to Band 40 when its remain in stable state.
I want to lock it to Specific band only. Can you help regarding it. I am using deluxe ROM with Android 9.
Thanks

Hello, were you able to fix this problem ?
Am going through the same atm
I'm facing the same issue on my N950F. Don't understand why samsung locked this on the Note 8, most new phones allow this setting. Any way to work around this with root ??
Edit: this is what worked for me https://forum.xda-developers.com/t/how-to-lock-lte-band.3681480/#post-74325453
TL;DR: Get org.vndnguyen.phoneinfo (no longer available on the play store), and run ServiceMode as root. Follow the guide above to disable unwanted LTE bands. Finally a solution that works for devices which Samsung disabled the "Band Selection" menu method (blue background issue).
