I have Korean LG G Pro F240L
everything works alright except that it doesn't fully use it's 3g capabilities
I live in an area where 3G signal is not that stable, usually 2-4 bars, signal can drop for a few seconds every now and then, I use telstra in Australia, which use 850Mhz/2100Mhz 3G network (850 in most areas, 2100 only for extra coverage)
I set the network preference as Auto, the trouble is that most of the time the phone sticks to 2G/GPRS with small icon on the top showing "G",
and if I want to use 3g I have to go to the network setting and change it from auto to "WCDMA only", the network will change to 3g (icon on top showing 3g) with signal strength about 2-4 bars
obviously with unstable 3g signals I can't keep it "WCDMA only" all the time, so I have to change it back to auto.
once it's in auto the phone will not revert to GPRS straightaway, it will keep going with 3g for a while and then if there is a drop of 3g signal it will then change to 2g/gprs and stay that way.
is there anyway to set the phone in "3g preferred" state where 3g is utilized automaticly whenever the internet is needed? (as far as I know, no such option exists).
do you have any trouble with your 3g settings? please share, thanks
I have discovered something new
in the hidden menu-WCDMA service menu-GSM/WCDMA band, when you click on WCDMA 1900 and WCDMA 2100, it shows success, whereas when you click on WCDMA 850 it displays fail
it seems that the phone is not using the stable 850 band at all, rather it relies on the 2100 band, this explains the erratic signal strength
I did a bit more digging
the band frequency for korean providers are
SK (S) 2G (CDMA) 800, 3G (UMTS/HSPA) 2100, 4G (LTE) 850/1800
LG U+ (L) no 2G, 3G (CDMA/EVDO)1800, 4G (LTE) 850/2100
KT (K) no 2G, 3G (UMTS/HSPA) 2100, 4G (LTE) 850/900/1800
also
telstra 2G (GSM/EDGE) 900/1800, 2G (UMTS/WCDMA/HSPA) 850 (main 99% population) /2100 (minor), 4G (LTE) 1800
AT&T (E980) 2G(GSM/GPRS/EDGE) 850/1900, 3G(UMTS/HSPA) 850/1900
strange that there doesn't seem to be direct connection/conflict between telstra bands and the LG U+ bands, i.e. if my F240L is able to use GSM and WCDMA 2100, why not WCDMA 850
I believe G pro is a global phone that supports all communication standards
I am unsure about the root of the problem, is it the matter of settings (i.e. can be solved by tweaking the service menu), or the problem of incompatible radio (hence can be solved by flashing appropriate radio)
also is there anyway to tell the band frequency the phone is using? I did my search and nothing yielded, I believe there is no such solution
my question comes down to how to enable/unlock 850 band on this phone?
If you use AT&T and have a korean phone, do you have similar problem? (as shown above AT&T partly relies on 850 band as well)
also if i guess right the problem is not limited to LG G Pro, any LG Korean phone potentially will have similar issues, I tried search optimus G forum but nothing turned up.
Same problem, korean phone wrong band

I got mine yesterday and have the same problem. Is it possible to select the band? mine is the SK version and I need to work with the AT&T band, can I just flash a new radio band? How do I get to the hidden menu?
Thanks!
I have kind of same problem with my f240
i guess if the at&t stock rom could resolve those problems
edit:
service menu:
5457#*240#
hidden menu:

no
I have since learned that basebands are all hardware encoded, at least for LG phones, and there is no way to enable WCDMA 850 band if it is not originally supported by the phone, flashing the radio will not change the hardware capability of the phone
The Korean LG G pro supports only
2G : 850/900/1800/1900 MHz
3G : 900/2100 MHz
4G, LTE: F240K - 900/1800 MHz (Band 8 & 3) F240S - 850/1800 MHz (Band 5 & 3), F240L - 850/2100 MHz (Band 5 & 1)
I have since change the network provider (who provides 3G on 2100 band), it's not ideal but it's the only solution for me
pls correct my if I am wrong
i have LU6200
inside my house 3G is suck, so i use GSM Only mode, but i only get G signal which mean GPRS i think and it is very slow. How to enable 2G/EDGE so i can get faster internet than GPRS?
Hi, I have F240k the 3G over 900 Mhz band is imposible.. I dont know if my phone is broken or I need flash with any new Kernel or something.. if any one can help to me would be very apreciate
3G over 2100Mhz is nice.
Gprs over 900 Mhz work fine but very very slow.
thank in advance

Hi I also have F240K from a week. I can't managed sim to work. Don't have any signal 2G/3G.
I tried most of the methods described here without success (flashing Telcel and Korean rom after, E988HK baseband, changing every setting in the service menu)
Which baseband do you use?
I can't use my new phone and I'm so desperate ;/
Hi, I sell my phone..really have seriously problem with the signal. I remenber that the best option was use the original rom...but anyway the signal was very bad. Sorry man.

Your expertise required in this regard.
Hi everyone;
First off, if this is in the wrong area, I'm sorry.
I've been looking to get my girlfriend a new phone for her birthday. She has an old Optimus 3D and the screen is cracked. I've been looking online to buy a Optimus G for her and came across a bunch online.
Most of which are listed as F180. I'm not sure what version this ends up being.
I'm hoping to get this phone for her and have it at least work on HSPA+ in Canada on the Rogers Network, but it would be great if it would work on LTE too.
I'm a little confused as to what frequencies Rogers LTE is on. I've read online that it's anything from 700, 850, 1900 , 1700, 2100 and 2600.
According to GSMArena the model frequencies are as follows:
2G Network
GSM 850 / 900 / 1800 / 1900 - E975, E973, E971
3G Network
HSDPA 900 / 2100 - E975
HSDPA 850 / 1900 / 2100 - E973, E971
4G Network
LTE 800 / 900 / 1800 / 2100 / 2600 - E975 (market dependent)
LTE 700 / 1700 - E973
LTE 700 / 2600 - E971
Click to expand...
Click to collapse
According to the Optimus G Wiki page Canada has the E971 and E973 models. If the International Version is E973, this should work on Rogers HPSA+ at least, and at least one frequency for LTE.
Is this correct?
Unfortunately I can't post any links right now because I haven't made enough posts, so I can't link to where I plan on buying the phone from.
Any help or suggestions would be great!

Hello everyone,
I just got my LG G3 today and I'm encountering an issue getting 4G LTE on my D855 (international version) on the T-Mobile US network. I looked around and searched the forums to find a solution to this 4G LTE problem specific to this phone. I tried going into the hidden menu (3485#*855#) and changing the bands and such, nothing works. I haven't rooted my phone or flashed anything yet, as I haven't found any tutorial in which doing so would resolve this issue for this specific model.
I do get HSPA on it, which gives me about 7mbps, much slower than I anticipated.
Does it mean that I won't get 4G LTE at all? I will be in Hong Kong for a few months and was wondering if I would get 4G LTE there on T-Mobile using this phone since it's the international version and they do offer 4G LTE over there. Anyone know if it works over there?
If there are no solutions, I might just sell the phone and get a different model that works.
I'm located in Southern California if that helps anyone.
@darkelfx, you need to check which LTE bands that model runs off of, and see if T-Mobile uses those. I work for tmo, and we did a lot of work on our network to make it more compatible with unlocked devices, however, I know that since there is a difference in the bands att uses, their devices do not pick up our LTE 90% of the time. They get HSPA+, just like you do.
These are the bands being used and my version is the international version (not the AT&T version).
2G Network: GSM 850 / 900 / 1800 / 1900
3G Network: HSDPA 850 / 900 / 1900 / 2100
4G Network: LTE 700 / 800 / 900 / 1800 / 2100 / 2300 / 2600
I do not get HSDPA+, I get the slower 3G speed, which is HSDPA.

for 3g you need to have 1700mhz as well
for 4g they use a combo 1700/2100 or AWS is the nickname.
Sorry to say but the D855 is NOT compatible with any U.S. LTE bands.

Yeah, I found this out as well researching the G3 before buying any of the variants for use on Tmo. None of the variants, outside of the 851, will work on Tmo's LTE. You'll get voice and 3G (HSPA), but not LTE connections with TMo.
As for getting LTE in HK, it won't be on Tmo's network, as Tmo does not have any networks in HK. You might get data roaming and all, but I haven't looked too much into that as I don't do much international travel. You would connect under a roaming partner there, if there are any under agreement.
Or you could swap in another SIM for use in HK.
This worked for me.
I had exactly the same problem.
Watch this video on YouTube for the G2, follow the instructions and it will work.

Hi, I use LG G3 D855 and looking for solution to get LTE on T-Mobile USA. After some research inside the forum, I decided to try to use CyanogenMod (CM 12.1) on my system.
It works well and now I can enjoy LTE on T-Mobile network, even though not pretty stable yet, but I am good with that since the OS still ongoing development.
You can try to download the OS on Cyanogen official website, and use the latest update available.
In order to confirm if you get LTE signal, beside check on your LTE sign, you can use LTE Discovery apps whenever you lost LTE connection and try to reconnect on an LTE signal.
Oh, forgot to mention, I am located in College Station, TX.
Hey everyone,
I'm on bell mobility in canada and bell does have 2600 mhz support. When I use the Lenovo Vibe shot, I only get 3G connection, NO LTE.
Is there a way to change this??? Is there a way to fix this? Hardware wise, it SHOULD be able to connect to 2600 mhz on bell mobility LTE but it doesn't. It goes only as far as 3g.
Please help me!! I'm trying to deal with this for weeks and I can't find any solution.
I'm wondering if you don't have the Chinese version vs the European version... Another member reported that even though the specs were listed as the same, some bands were not present in the Chinese variant.
http://forum.xda-developers.com/showpost.php?p=62737607&postcount=17
FML! It is the chinese version! but i bought it from etotalk.com! It listed 2600 mhz frequency explicitly....
is there anyway to select the LTE band?
