One of the good things about the gs6 is the ability to for b12 and even better ability to choose preferred band in automatic mode.
Does the m9 have some sort of ability like that?
You are talking about the WIFI channel 12 (which is illegal to put your WIFI on in the US)?
Actually I think he is talking about forcing a specific LTE band... (in this case LTE Band 12 which I think is for T-Mobile). Specifically accessing the LTE Band service menu.
For any Samsung device you would enter *#2263# and the "LTE Band" service menu would open up and you can force a specific band. IF this is what he is talking about, it’s actually a great feature because you can "lock in" LTE to a specific band, I use to do this all the time in the Philippines so I wouldn't get kicked off the LTE band. You can also see what LTE bands the phone supports.
When I had the M9, I looked everywhere and tried to find the code to access the LTE menu but I was unsuccessful. Maybe someone here has the code to access the LTE service Band menu. There were some generic codes that work for Google in general BUT none of them worked on the M9.
Try *#*#4636#*#*

*#2263# doesn't work for me
But yes LTE band 12
##DATA# on Sprint lets you do something like this, but I believe that code is Sprint-specific.
Hello there hope all of you doing well
i had Tmo SGH-T999 S3 which is unlocked but after unlocking its stuck on 2G Network i couldn't use 3g network
i search on google and i found this code :*#197328640#
but i don't know how to use it any way can you help me
wish best times 4 you ^_^
Did you sim-unlock the phone using a code?
I'm also having this issue. I have TMO SGH-T999 S3 sim unlocked before via software (not unlocked via code) and always stays on E (2G). I am thinking that i got messed up after the unlock. My IMEI is still intact btw.
First thing is to double check that your IMEI exactly matches the one on the sticker under the battery. If it checks out, the next best step is to reflash your current or newer stock firmware. (This can be caused by mismatched firmware so by flashing it you will either fix the problem or eliminate it as the cause).
You may also want to check your IMEI against the blacklists online. Especially if you bought it anywhere but a retail store.
Unlocking via code or secret menu should not affect radio bands available in the phone.
WCDMA Band preference
I've checked the WCDMA (3G) band preference available in my T999 S3 and below are the only option available:
The mode preference menu: *#2263#
The information menu: *#197328640#
WCDMA 850
WCDMA 900
WCDMA 1700
WCDMA 1900
WCDMA IMT2000
WCDMA ALL
... and found out my carrier band preference for 3G is 2100. Seems i'm out of luck for 3G data and since this T999 cannot support 4G LTE. I guess i'm stuck on E (2G) data unless i use WiFi.
P.S - Is there a way to add a 1800 or 2100 band preference to WCDMA? :fingers-crossed:
Check the General section in AT&Ts forum. They had something like this if I remember right. They could enable use on a different band, but I don't think it would stick after a reboot. It's been a long time since I looked at it though, so they may have made some more progress on it.
Goodbye 2G (E) data connection
I'm happy to report that my (WCDMA) data speeds is now functional on my SIM network carrier! :good: Loving the speed browsing at last . Although showing as 4G but i know my T999 is not capable of that and not very sure.
Again, thanks DocHoliday777 (I don't know how to link your name) for giving me the idea about the Modem mod. I just followed the guide on the link below and used the NV Data backup from T999L file. So for any users of T999 you can try this mod but please do it at your own risk and don't forget to backup.
I hope this T999L modem mod can be included on the newer root66 baseband/firmware so it can be permanent?
Anyway, just follow the guide on the link below and hit thanks!
http://http://forum.xda-developers.com/showthread.php?t=2344627
P.S - To access the modem setting on my SGH-T999 I've used the code *#0808#. And my final WCDMA setting i chose WCDMA ALL. Goodluck!
Hi, I am new to the forum and want to share my experience about LTE BandSelection.
As discussed in the previous thread, you can access to Verizon Hidden Menu called LTEBANDSELECTION. By default, Band2 Band4 Band13 are checked and Band5 is unchecked. However, from LG website LTE 3/7 is supported for Roaming, but those bands are not on the list.
I can confirm that at least Band3 is working because I am on a carrier that uses Band8 and Band3. The problem is that, when I try to change the LTE band selections above (ex: adding Band5 to the list), it seems that LTE3/7 is not working anymore. After changing it once, I only get 3G signal without any LTE. The only way that I can get the Band3 signal again is going back to the original stock rom (13b) again.
It is weired that there is no hidden menu to select Band3/7. Do you have any idea on this problem? Thanks!
EDIT: If the dialer code doesn't work for you, see this post for another way to access the Hidden Menu.

US998 Hidden Menu LG V30/V30+
So, I went looking for the hidden menu dialer code for the US998 LG V30.
https://www.reddit.com/r/tmobile/comments/75tbsc/lg_v30_and_others_engineering_menu/
*#546368#*998#
That's a different menu, and doesn't provide the band locking option and you can break your CA and LTE combos if click the wrong thing. Just wondering if that code works. You can get to the Engineering Mode, though.

Found it. Literally you copy and paste this code into your dialer. Do not hit "call". Once you paste it in, the menu instantly pops up.
Unlike for the T-mobile variant, it doesn't let you checkmark off all the bands you want -- at least with AT&T Prepaid, which I have. I think the bands it shows it dependent upon the SIM card you have in your phone.
I was able to click each LTE band my phone IS showing and with one exception (LTE band 30), a box popped up and "Success". Whatever that means.
I think if I had AT&T postpaid it might show more bands. (AT&T Prepaid doesn't allow domestic roaming, but does have roaming in some other countries.) Or if I had T-mobile it might show different bands, like even LTE band 66. Since I have AT&T Prepaid -- with no U.S. roaming -- it's not going to show me a band I'll never use? At least that's my working theory. While the dialer code is the same, possibly options are different depending carrier/SIM card[/B]
You can also go into the Service Menu and turn off MOISTURE DETECTION. Just an FYI for those who need to know that.
I did go into the some of the VoLTE/Wi-Fi calling settings. While VoLTE was already enabled, VoWifi (Wi-Fi calling was not). I enabled it. As an AT&T Prepaid customer, we don't get that yet, and I don't really need it. (I have Google Voice.) But I checkmarked it to enable all that. Didn't seem to break my phone.
I took some screenshots to get into the LTE bands menu, but I didn't take screenshots of the other stuff. Of course, be careful! You can break functionality.

LTE BANDS on AT&T Prepaid
Okay anybody know how to get the LTE band selector back to automatic? Apparently clicking on one of the bands chooses only that band. I am stuck on band 12 which is prevalent in the Atlanta area, but I would like all bands.
By clicking on band 30, I had no LTE whatsoever . I had to click on band 12 to get some LTE signal.
In that menu, I do not see a method to choose a batch of bands. I only see a method to choose one band at a time. Whereas before I mess with the menu I had several bands automatically depending upon signal strength.
I rebooted my phone, hoping the band selector was only for that one session . But still I'm only seeing LTE band 12. I don't want to reset my phone. This got to be away to make it go back to automatic.

Whatever I just did, now I can get other LTE bands. I'm now on LTE band 2.
But I didn't choose LTE band 2, it just found the strongest signal. Whew.
Thought I was going to have to reset my phone.

Funny, i did the same thing this morning when playing with the menus. I thought it was a checkbox and saw a 'SUCCESS' toast show up on clicking. Oh no , what have I done.
I rebooted the phone and everything seems to be back to normal.
A slightly different code for the AT&T version of V30
The code didn't work on my AT&T version, BUT!!!!!! ........ I noticed how the last 3 digits correspond to the unlocked version and substituted them with 931 which corresponds to H931/AT&T phone version and voila!! I get into the hidden menu.
So for AT&T version of V30 the code is *#546368#*931#
Enjoy!
The menu looks a bit different though e.g. band selection is not there

I'm still concerned I may have done something to prevent my LTE bands from automatically switching properly. I've been on LTE Band 2 for two days now and only LTE band 2. Normally traveling to and from work (30 miles down I-75 and across I-285 perimeter) I'll switch bands, according to LTE Discovery app.
But today I'm heading into north Georgia where LTE band 4 is prevalent, so we'll see...
reposting here also as it's very relevant to the US998 hidden menu.

Hey All,
I unfortunately messed around with the LTE Band Settings on my US 998 (US Cellular) in the hidden menu and am now worried that the phone is locking to specific bands. Right now, no matter how many times I reset network settings and restart the phone, it will only lock to one band (12 or 4). The lock is dependent on which LTE Band Setting I select. Anyone know where in the hidden menu I can reset the band selection? Any help would be appreciated.
Thanks!

Please tell me exactly what you did to fix the problem? When you factory re-set, did you allow Google to restore your data and apps? I really don't want to do a factory reset if I don't have to.
I've already tried airplane mode, as well as chosen other bands (I stick on them unless I re-select LTE band 2.) As well as rebooted multiple times daily.
I've been stuck on LTE band 2 for 4 days now. I selected LTE bands in that hidden menu and it stays only on the one chosen. Before that I was stuck on LTE band 12, but 2 is better than 12 if I have to be stuck on one.

Unfortunately that doesn't help. It's the US998 menu. You click it, it chooses that band. You click another it chooses THAT band and only that band. It stays in the last band you chose and only that band.
I can select another band besides band 2, but I would then be just choosing another band to be stuck on. I did that initially when I was stuck on band 12. Now I'm stuck on band 2, which is better than being stuck on LTE band 12 in the Atlanta metro area.
I went up to North Georgia last weekend where AT&T LTE band 4 is prevalent, and I was on WEAK LTE band 2 the most of the time, and then on HSPA. I never switched to LTE band 4.
That's why I asked the guy exactly what he did to fix it. He said factory reset, but I would like his details. I don't want to completely reset my phone for nothing. If only a true factory reset will fix it, I'll wait until next weekend when I don't need my phone during the daytime.
Also, did he allow Google to restore data and apps?

Has anyone found a solution to this? I have tried a factory reset and it did not solve the issue. I also tried a couple things such as changing the RAT Selection to WCDMA ONLY (since VZW) and then LTE ONLY and then to LTE/WCDMA but that results in no service at all whereas I at least have service with WCDMA ONLY or LTE ONLY.
I imagine there should be a simple way to fix this as it is literally just disabling bands in the modem...it is just a matter of figuring out how.
same issue here. anyone succeeded in restoring the default settings? weird hidden menu on this Phone and keeps me frustrated...

Hey Chazz, sorry for the delay. I have notifications turned off. But yes, I had to do a factory reset from scratch. I didn't restore any settings and started with a clean slate. I then used LTE discovery to see myself connecting to different bands. Toggling airplane mode showed band 4 and 12.

Thanks for the answer. The V30 with the problem is now my backup phone, as I'm using a V30+ as daily phone. I didn't dare touch this menu on that one or my wife's V30.
I have reset that first phone, but it no longer has a SIM card in it. Maybe next weekend I take it for a drive...

messed it up, too. It is definitely stupid not to give users the right to select all the bands or to use auto mode. Seems that we have to wait for the bootloader unlock to have that right back?

Yeah, the US998 needs the T-Mobile hidden menu, where you can select all the bands you wish, not just one at a time. Very strange design choice from LG.
There is an option in the hidden menu to reset networks. Did you see that? Maybe that's what needs to be chosen?

If factory reset doesn't work, then flashing this probably won't. I don't know for sure. However, in that same hidden menu mode, I saw network reset choices. Not in the LTE bands section, but a neighboring section.

Hmmm... very strange. I know I saw something before, but I can't find exactly what I remember.
Anyway, I see the R&D Factory Reset in the Hidden Menu. Is that some kind of super duper re-set? I don't know. It's in the Hidden Menu for a reason.
I also see Network Settings Reset in the the regular Settings menu. I don't have a SIM card in this phone, but if I did would it re-set ALL my network settings?

I think the Network Settings Reset in the regular settings menu is already covered by the factory data reset. Thanks for getting back to us though. I'm not entirely sure if Factory Data Reset worked for me or not. T-Mobile around where I live is mostly Band 4. I've looked through cellmapper for towers that had band 2 and were spotted recently, and as I drove by them I didn't notice my phone connecting to anything other than band 4.
