LG G4 Band Selection Reversal - G4 Q&A, Help & Troubleshooting

I had to use the hidden menu in order to connect to LTE only, band 20. However, when switching back, it will now only connect to band 20 and no others, such as band 7. Is there any way of reversing this? Like removing the specific band allowing it to connect to any?
Many thanks.

how to enable 850mhz on i9001 galaxy s plus

i have a galaxy s plus.
i want to enable the 850 mhz band.
anyone know how?
i have a Galaxy S I9000, i'm supose it's similare:
On y phone, 850Mhz band is desactivated by default.
try on phone keyboard:
*#*#0011#*#*
You must arrive on a menu:
do back and go to Phone controle and Band Selection
Doing this enable band activation on software, if your phone's modem not enable to working with this band, the result is it's not working with the band frequency anyway...
I'm try this for enable USA 3g band on my I9000 from europe, and i'm able to activate band, but it's only partialy working (have 2100Mhz 3G (VTR) working with this, but not the 900Mhz/1900Mhz band used here by Movistar(Chile) for 3G.
it does not work. i see the menu but when i press
back, i do not get anywhere

[Q] Expose band in use if you have a rooted/ CM phone?

my understanding is that typically only Samsung's own Field Engineering app will expose and even force the Band in use, often, typically "band IV" or Band II when I have a 3G/HSPA connection (=AWS or PCS band). Is there a way using a rooted phone loaded with a flavor of CM to see that as well? (Either just display the band or even lock on a band. I'm asking if there in an alternative engineering app that would work... if you run CM.
Or is the only solution to return to a stock Samsung/T-mobile Android version if you want expose "Band in use"?

Not sure if this is what you are after, but go into Settings and under Wireless & Networks choose More...then choose Mobile Networks, in there you can choose Network modes and also force to use only 2G networks.
Thanks for the reply. It's not what I meant though, I want to see which band I'm getting service on. For example AWS or PCS band. my Samsung with stock android on the above examples it would say band 4 or band 2.
But I suspect you need stock android from the OEM to keep that ability.

Force band 12

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.

LTE Band Selection Problem (Band3, Band7)

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!

Useful tip for switching LTE bands in the G710EAW (and possibly other versions)

If you try to change bands in the service menu (e.g. from Band 4 to band 2) and you have LTE but phone calls don't work at all (just says call ended instantly), just go to "network mode" and select automatic, which will get voice working again on your new band.
Turning the sim card off and back on won't fix that--that will just make the band reset to default (with voice working) which isn't want you wanted if you were switching bands.
This can be useful on low tier providers if one band is lagging horribly and another band is more reliable.
I just recently discovered the service menu, does this actually enable bands that normally aren't active? I see Band 71 here which I thought was only available on the TMobile US variant, yet here I am with the ULM model and it shows it in the menu. I'd like to enable it in case I'm ever in an area that supports it, but I'm not sure what this menu actually does?
