Note 8 (SM-N950F) Lock network BAND - Samsung Galaxy Note 8 Questions and Answers

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).

[Q] Enable network mode menu or remove lock for changing modes

Hello
Now that we have root I would like to change my network mode, my S6 edge is only in LTE/GSM by default.
I don't have the network mode menu in settings, and if I go to *#*#4636#*#* I can see all the possible settings, but only a few of them are enabled. (GSM only, LTE only, WCDMA only, LTE/GSM), but not the one I want LTE/WCDMA/GSM, when I select it, it goes back to the option previously selected.
Anyone else dealing with this?
Will root help us to find a way to change this?
Thank you
your problem is the same to my s6 SM- g920F
Try you tube video " How To Change Network Bands on Any Samsung Phone Without Root" haven't tried myself

[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.

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, 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.

Unlocking "Only LTE" mode in Honor 9 lite

Hi friends, we all generally hate it when network automatically switches to the mode in which phone gets strong signal. I mean we really don't like when phone automatically switches to 3G or 2G mode from 4G when the signal of 4G is weak. Since there is no "Only LTE" mode in our device (Honor 9 lite) we need to enable it. How good it'd be when we could enable it without rooting.
Here's the process:
1. Download "Settings Database Editor" (attached below)
2. Open the app
3. Find "hw_networkmode_preference"
You will see its value like "9,3,2,1"
4. Edit this value as "9,3,2,1,11"
5. Save
6. Reboot
Now go to settings > wireless & networks > mobile network > preferred network type
You will see so many network options unlocked.
Select "LTE" to stay in LTE mode no matter how weak 4G signal you have there.
* Root is not required*
Hi, I have got Honor 9 Lite Indian version but when I am using a US based SIM, only Data & text are working and I cannot make & receive calls. Appreciate if anyone could guide on how to resolve this.

You must be using airtel. FYI Airtel doesn't support voice over 4G. It's their problem. In order to make calls from airtel select LTE/wcdma

Set the settings only to 11 then you will have all the options available. Hope this works for you.
Deleting that option helps in My Honor 8x,I am getting a lot of options now

Blank service mode

Hello,
I use the Three network in the UK with an unlimited data plan and they provide a service called 4G Super-Voice also know as VoLTE.
To get this working I had to flash my Note 9 with the 3 firmware which is annoying because of the boot screens but its worth it for VoLTE.
Anyway, I can only access 4G Super-Voice if I put my phone in aeroplane mode and then off aeroplane mode. I then can see using *#0011# that I am using band 20 which is used for 4G Super-Voice.
With this, I can access VoLTE, better signal and faster 4G speeds. But after 30seconds it goes back to Band 3 and I no longer have access to VoLTE and the faster speeds Band 20 offers.
I have had a look online and a few people have fixed this on other devices by only letting the phone access Band 20 and disable the rest. On my Note 9 when I try entering Service mode using *#2683662# I'm left with a blank screen with no options to select. Not sure if 3 have locked this on there firmware or if I'm accessing the menu wrong. Any Help is much appreciated. Thank You

Yes, you can lock out certain bands while allowing others, but the *#2683662# code has been deprecated in the latest models/firmwares.
Enter this diag code *#2263# or *#2766338378#, tap LTE Bands Preferences, one by one deselect all the bands you don't want (especially band 3), tap on Go Home or Go Back/Previous, and finally tap on Apply Band Configuration. If you did everything correctly your phone should no longer pick up the unwanted bands.
Here's some more information about this issue.

Question Prefer LTE & Missed Calls

I'm running xiaomi.eu 13.0.8.0 on my Note 10 Pro currently, though I'm not sure it matters for this.
When I have the Preferred network type set to "Prefer LTE" my phone locks onto LTE towers with a poor signal, typically around -117 to -123 dbm, ( > 2km away, 0-1 bars). Sometimes calls work, but often I get reports that people aren't able to call me, and if I make a call it may take several minutes of retrying before it finally switches to UMTS or GSM and the call goes through. There is a strong GSM signal close by, but it typically refuses to use it and prefers the unusable LTE signal instead.
Short of setting it to "2G only" is there any setting that would let the phone switch to a usable signal, when LTE is so bad?
VoWiFi might help in this case to get around the problem, but I haven't gotten that working, either.
reset phone settings. prefer it
redmi note 10 pro same device as yours and I know as I am facing another bug, same would U bcz firmware is latest I have debloated many apps from adb pm.... command.
A Bug I know exist most people wont know is about Cellular network Band. It adds jitter in connection.
And I have solution for that one but that require root. maybe not
But Trust me I know problem Thats it we can find solution
To know the problem, It is actual in band selection. If u check it and find a fix please share it here.
I am writing my fix here
---> Download app from Playstore called "Hidden Settings For Android" to see the problem.
---> now search "band"
U have to use little brain and see all three selections name.
---> FUN read this " Two system apps called System settings and Miui System settings have control over band selection. Right!
---> One open settings for band selection and other opens settings for band selection as same as we think but they are different apps and have different data storage settings they override each other if u select one band in one settings and two in another make both their selection buggy.
By default when i didnt found this I was experiencing bad network.
Then I selected same band on both settings and keep them open in background and by network run back to normal * more faster than other devices on same network provider
As soon as I remove both from background, later bug starts to happen again.
Interesting. I ended up getting vowifi working by contacting my service provider and asking them to enable it on my SIM. So I keep the phone in airplane mode with wifi enabled when I'm at home. That's working much better.
I did try "Reset Wi-Fi, mobile networks, and Bluetooth" before, several times, but it didn't seem to make a difference.
