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:
3845#*240#
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.

Hello i was using 4g lte on my f240k smoothly, than i updated to lollipop my imei was gone and afterwards i again downgraded to kitkat but problem is 4g lte is now nit working for which i downgraded
Now my carrier also saying handset is not compatible. But previously i have used 4g lte on this same device.
Your expertise required in this regard.
hi everyone,
i would like to know if the LTE frequency of 1800mhz in LG G PRO E988(Philippines) can be change to LTE 2100mhz? because the ISP(Smart) here in my country only gives the frequency of 2100mhz for their prepaid LTE service... and this phone of mine has WCDMA only for the 2100mhz and only 1800mhz and 2600mhz for its LTE as per its box says...
i have read somewhere that this frequency band is encoded to the hardware(i dont know if its true) but is there a way to change it? like changing to custom rom, kernel, hacking, etc....
i really need to have a frequency of 2100mhz in LTE in this LG G PRO android of mine to support the prepaid LTE from my ISP ...
experts here, please need badly your helps guys...

@ mervin
thanks for the reply.
probably that is not an e988 version.
lg g pro has several variants as we know...
the e988 here has no 2100mhz for the LTE ---> http://m.gsmarena.com/lg_optimus_g_pro_e985-5254.php
and also as i mentioned above, no 2100mhz also for LTE in its box, only 1800mhz freq.

I don't know how firstpost reached that conclusion. Not any literature on the net about e988 has ever mentioned LTE being present, hidden or otherwise... For example, this,

e988 LG G Pro has LTE capability but only supports 1800mhz and 2600mhz frequency bands (see the GSM Arena link i have posted above).
by the way, LTE also stated in its LG box
any help please...

Theres NO changing of bands on this phone... Whats on it, is whats on it.
Bro, unfortunately LTE Band is hardware-variant-dependent and cannot be changed through software. The E988 variant only works on Globe LTE which is 1800mhz (B3), unfortunately you have to subscribe to 1 of their expensive postpaid plans to use LTE. I myself have a SMART prepaid LTE sim, and so I bought an AT&T E980 which has a 2100mhz LTE frequency, but what I failed to realize is E980 uses Band 4. SMART LTE only works on 2100mhz Band 1, so I am unable to use Smart LTE on E980 also. The only G Pro variant capable for Smart LTE is the korean F240L.
@ hyel
thanks. that's sad to know...
@ jrtancinco
thank you for the in-dept information bro. yes, i heard i can connect to Smart LTE thru their postpaid plan using my E988. Kinda confusing why there is so called Band 1, thought 2100mhz is enough.. I prefer the Smart due to Globe signal here in my place sucks big time. might as well buy a separate pocket LTE wifi, and keep this fast and amazing LG G PRO
------------------
*** UPDATE - i have tested three units of high end android phones (Samsung S4, LG G PRO, & Samsung Note 3) using postpaid LTE SIM in an unlimited Smart LTE Plan inside one location, versus a dedicated LTE Pocket Wifi; Result is, all the three high-end handsets have far lower speeds of the LTE compared to the LTE Pocket Wifi had delivered. Seems the LTE pocket wifi device has the dedicated hardware for more power and reach compared to a LTE built-in capability of a phone.
I now can conclude that its better to use a 'dedicated' LTE pocket wifi device than the built-in LTE of a smartphone handset if you want better LTE speed throughput.

LTE not WOrking on 1800mhz on My E988 Optimus
Hi there I am using LG Optimus G Pro E988, but I there is no LTE on it where my carrier support E988 on 1800mhz. Can anyone help me on this?
Hi everyone.
I'm using T-Mobile LG G3 D851 right now. I upgraded via OTA method few days ago. I noticed a bug or what I should say I don't know. LG G3 D850 have LTE feature. When I set network mode to AUTO GSM/WCDMA/LTE, it shows 4G when I turn on Mobile Data. I checked the About Phone section and also checked Network State. In network state, I always find Mobile network type showing HSPA or HSPAP. I never found LTE. I contacted my Service Provider. They informed me that you've an LTE SIM card and you have full LTE Signal Strength in your are. Please anyone tell me, why I'm not getting LTE?
At first I got kind of confused. The 4G icon indicates LTE on stock ROMs. HSPA, however, indicates 3G. Here's the deal, the G3 phones are not equal. The D851 is a T-Mobile GSM phone. The D850 is also GSM I believe but for AT&T. They support different bands. Even though the phones and your SIM is LTE capable, that doesn't mean they both work the same on a given network. You're in Pakistan on the Zomg network. The D851 can't take advantage of the services there.
Screenshots below show that the D851 can't do LTE there but the D850 can. It's always best to check the bands a carrier uses and compare them with what a phone supports. GSMArena is a good place to check that.
You might be out of luck with the D851. Not sure.
@iamqaisarkhan, here's a list showing the LTE bands supported between the two phones. D850 supports more bands including the one used by your carrier.
