[Q] LG G pro 3G issues - LG Optimus G Pro

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:

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.

Korean Optimus G Bands

Hi, I am in Korea right now. I want to get a cell phone that I can bring back to Canada when I leave in a few months.
Right now, I have the Vega Racer 2, and it'll only run on my provider back home on 2G (Rogers).
I can't seem to get the right information, so I was wondering if you guys knew what bands the Korean variants of the G has.
From research, it seems that only the S3 has quad-band 2G/3G bands. But I had a S3 back home, and that white Optimus G is mighty beautiful and exotic (they don't have the white model outside of Korea).
Thanks!
Optimus G is Quad Band 3G. The only difference is the LTE frequencies it supports, for example the one I have runs on 700/1700/2100 which is valid for Virgin Mobile Canada, Bell, Telus and Sasktel.

Tim4, I have F180K, and It's not working in WCDMA 900. I tried with Korean ROM, CM 10.1, my friends made tests with EU ROM+ korean baseband - so, I suppose you didin't try it...
Ofcourse im not, im using LTE 1800.
The freqs i wrote here are from network settings of F180K, try to it set as 900mhz, not an auto.
To enter network settings you have to input secret menu code, which i dont remember anymore, google it.
Also note that E975 stock rom doesnt have the hidden network settings (Or the code is different), only stock F180K rom has one.
I was testing it, and as i remember, (in stock Korean ROM) band 900 refers to GSM, same in CM 10.1
Does anyone know the secret code for the service menu as i am also trying to get my korean phone phone to work on 2100 or 2600 lte.
Thanks

UMI X2 and T-Mobile 3G

I purchased the newly released UMI X2 Android phone. I am unable to use the TMobile 3G network. I am only able to use 2G/EDGE.
Voice and data quality are very bad, almost the phone is unusable. I spoke with T-Mobile and was informed that my modem does not support 1700 MHz and there are effort to re-farm TMobile network to support 3G on 1900Mhz but not set date yet. When I scan for available network I get three networks were available
T-Mobile 2G
AT&T 3G
AT&T 2G
Operating System: Android 4.2.1 OS
Processor: 1.2GHz MTK MT6589 quad-core processor
Connectivity Technology: GSM network & WCDMA - Standard SIM card
Network Band: GSM 850/900/1800/1900 MHz & WCDMA 850/2100MHz
Data Technology: GPRS, EDGE, HSPA
Baseband version
MOlY.WR8.W1248.MD.WG.MP.V2.P1
I would appreciate any help to get my phone to work on 3G.

Did you make any progress with this? I recently purchased UMI X2, for use with T-Mobile UK. But have the same problem of not being able to connect to 3G networks - it works okay on 2G/EDGE.
I know the phone supports 3G on 2100MHz, and there's been some debate whether it supports 850/900MHz as well, but I've not found a definitive answer to that.
There's an operator in the UK (Hutchinson 3G UK Ltd) that only have a license for 2100MHz. So I was expecting the phone to work fine on their network- but no go... phone won't register on network at all - even though it shows in the available networks list.
I'm now searching to see if anyone else has been having problems - as it's beginning to look like faulty phone hardware - rather than trying to use unsupported frequencies...
acid meaand
I am still in the same situation, I am unable to use the 3G network for T-Mobile.
I am looking into getting 4G Wireless Hotspot modem $50 from the same carrier, use my SIM card on the modem, and use my UMI X2 as pure IP phone. There are many issues, but it looks promising.
Please keep me updated with any progress you make.
Regards;
I have the same problem...
I have this same problem with a operator here in Brazil. Every 3G operator in Brazil, using 2.1GHz band, works fine except one: VIVO.
I can see the network when I click on "manual search", but the phone can't connect. My baseband is:
moly.wr8.w1248.md.wg.mp.v7.p1 2013/04/10 00:39
How can change this baseband to another? I tried to update firmware but unfortunately the newest firmware has the same baseband version.
firmware update will not solve the problem
Firmware update will not solve the problem. Until the manufacture identifies the problem and provides a solution, the problem is outstanding.
Beside the hardware has to be compatible and can support more frequencies which no one can confirm for the UMI or any other chines unlocked phones.
But, this is just my humble opinion.
I Found a solution (at least for me)
I think I found a solution for my problem. I flashed this very new (2013/07/17) rom, with a new baseband MOLY.WR8.W1248.MD.WG.MP.V7.F2.P1, 2013/07/10 23:14 that corrects 3G dropouts and disconnects. Now my 3g works find, with H and sometimes H+. Fast and reliable like it should be. The link for this new ROM is:
http://www.needrom.com/mobile/umi-x2-based-official-for-europeus/
Thanks for the update.
I have two questions.
1- There are two files in the link you provided UMI-X2-basedon_Official_250613.zip and UPDATE_UMI-X2-THB-ROM-based_on_Official_170713.zip. Which do use?
2- You mentioned the updated corrected 3G dropouts and disconnects, but do you know if the update have these frequencies to get 3G?
3G (850, 900, 1700, 1900, 2100 MHz)
HSPA+ 42
P.S
GSM/EDGE/GPRS (850, 900, 1800, 1900 MHz) original specs

I used the file UPDATE_UMI-X2-THB-ROM-based_on_Official_170713.zip. It was based on the Official ROM from 07/17/2013, but I was unable to find the official stock version. This version has a very new bandbase that, supposedly, fixed the problem with 3G on some operators.
3G on Brazil is on 2100 MHz, sometimes on 850MHz but in my case the problem was on 2.1GHz band. Three WCDMA operators in Brazil, all in the same 2.1GHz frequency, work fine, but VIVO doesn't. Now, with the new rom, it works with no drop outs for over a day now.
no changes or additional frequencies
I successfully applied the update but no changes or additional frequencies
I have serious issues with HSDPA, t-mobile uk works but only on GPRS and it keeps dropping out. GiffGaff seems to work without dropping out. It has worked for a minute on HSDPA today but only once. Other than that t-mobile has been dropping out badly. GPRS works for a bit then it drops out. I have took an MTK modem log with MobileUncle Tools to see what it says but haven't looked at it yet. Trying to work out if it is a hardware issue or Baseband.
I get this from my X2 Radio Logcat:

[Q] E975 3G connectivity

I just bought a Optimus G E975 that operates with only 3G(HSDPA): 900, 2100 MHz frequencies. I'm currently on the Telstra network that only provides 850, 2100MHz frequencies for 3G. The 2100MHz is available in locations where there is high volumes of usage (city for example) but I'm never in these locations when using my phone so it's resorting to 2G connectivity.
Is there anything I can do to make the E975 compatible? or is it the case of the antenna design and therefore I'll have to change phones?
Note: I didn't know at the time of purchase but Australia has a LG Optimus G E975k designed (850MHZ, 2100 MHz for 3G) for the networks we have here.

After emailing the supplier about my issue, they suggested trying a new sim card. Could this be a real possibility?
Below is the message they sent after I informed them of the issue:
2G(GSM): 850,900,1800,1900,
3G(UMTS): N/A
3G(HSDPA): 900,2100, (not Next G
It should be related to the network APN settings. Also, it may due to your sim card problem, as this phone need to use new sim card.
Please contact your sim card service provider to change the new sim card, it is free of charge.
For the APN settings, you can go to settings, mobile network, ,then access point name (APN). Then you can click your service provider, then select APN. Then you can change the APN link according to your sevice provider official link
Thanks for your good communication
Please keep in touch, as i believe everything can be solved through communication

According to the official LG website and many others, the hardware only supports 900 MHz and 2100 MHz frequency on a 3G network. I wish what you were saying was true .
I tried flashing E975k firmware (i'm assuming it would install a e975k baseband modem) but I still couldn't connect to 3G. So it must be due to the antenna design.
I appreciate the response.
rogers(canada) also uses 850 mhz ...so maybe asking for an e971/973(forgot which one is bell,which one is rogers) modem??
are you suggesting to flash the e973 firmware since it has the 850MHz baseband modem? I've been flashing all e975 software.. havnt tried e973 yet
You will have 8 mpx camera instead of 13 mpx if you flash the e973 firmware but maybe you will solve your connectivity issues
I said modem only,not whole rom.

3g problem
The phone won t stay connected on 3g. I start the data connection, 3g, but after a some time the connection stop all by itself with no posibility to turn on again. Only restarting will help, but ,again after a while same problem. The only pisibility to turn the connection on is only by restarting the phone. When i switch the 2g connection there s no problem.

[Q] Band frequency/LTE/3g Lg Optimus G Pro F240S

Hi,
I have bought and just got delivered a brand new Lg Optimus pro from Korea. The problem is that it would not recognize the band frequency, either for 3G nor 4G. The version I have is f240s and the frequency for 3G is 900 and 2100 (both is used by my currently operator) and for 4G 850 (B5) and 1800 (B3). Now, GPRS/EDGE works and the frequency for 2G is GSM850, 900 1800 and 1900.
I live in Sweden and my operator (Tele2) uses same band for both 3G and 4G. My question is why it won't work. Firmware issues? I have used the commando for the LTE menu (5467#*240#) and when I am trying to change the band for LTE I get a message "getbal has no fram value".
I would really much appreciate any solution or step in the right direction! if anybody has more questions or would like further information don't hesitate to ask!
Thank you again.
It passed about 3 months since you posted. Have you solved the problem? I have an LG Vu 3 (also Korean) and it behaves exactly like yours.

[Q] LG G3 D855 4G LTE issues on T-Mobile USA

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.
