Hi everyone,
It's always been known that there is a 900/2100 Defy and an 850/1900 Defy.
I got mine from my 850mhz carrier in Australia. I am visiting Hong Kong at the moment. I purchased a one2free SIM (900mhz network), changed my baseband, and got on data with full HSPDA! I can download around 200kbytes a second.
Thought I'd share for fellow travellers.

Hi, how did you change the basebands to HDSPA 850/1900?
Look up "baseband switcher for defy" in Google. You'll be surprised. It's not really news...
Thanks for your answer, but I have a Defy+ with cm7. I tried with basebandswitcher and baseband of cyanogen but didn't work, they didn't change frequencies and the phone lost signal. Do you know why? Thanks
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

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.

Please tell me what did you do regarding this issue ?
Unstable/Weak phone signals
Singles on my korean LG G Pro are very unstable and after every few minutes my phone shows "Emergency calls only" with an empty signal bar and then suddenly gets full signal back with in few seconds.
I am using custom Android 4.1.2
Same time my signals on my Xperia Z phone with same network remains stable at same place.
Is it a software issues ??
If yes then how I can resolve it ?

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.
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:

First of all, I live in Europe and have ZL 6502. Because of low network I entered *#*#4636#*#* and in Phone information tried to change the Radio Band but only available was US BAND. I ve tried flashing 4.1.2 - 10.1.A.1.434 - GLOBAL, and Generic LAM (b) Generic GEL 1271-5120 10.3.1.A.0.244 R5B version, but still shows only US radio band available. PLEASE HELP ME if there is ANY way how to get EURO BAND. Which firmware I should flash?
PS. My phone is not rooted, with locked bootloader, I will do it ONLY if its necessary.
Thanks

Just reload the software using PC Companion from Sony, and DON'T select a band when you're done.
I did that too... So I got a suggestion on xda to do a full factory reset. It solved the problem.
Also, try to stay away frm such settings that u know nothing about( I once did that nd had a hard time). Tinkering with them causes a lot of headaches(a lot of backuping nd stuff)
Hope it helps.. Don't forget the thanks buton on ur left
I already did that, and the phone I mean network works more or less ok, but I was wondering if there is a way somehow to change the radio band. Because US Band works on diffrenet frequencies than EURO Band, and I think it would be more compatible wit my carrier.
Thank you both for the reply

No unfortunately there is no way that u can change bands other than provided.
I wud also suggest to ask this on another forum, bcuz u wont find many ppl here. U might wanna try Xperia Z forum or try searching on xda GENERAL.
thats the most i can help.
Good luck!
How low is your signal?
The countries of Europe use the dual band frequencies of 900-1800. The US uses mainly 850-1900.
But the Xperia ZL C6502 supports all of these:
C6502/L35H
UMTS HSPA+: 850 (Band V), 900 (Band VIII), 1700 (Band IV), 1900 (Band II), 2100 (Band I)
GSM GPRS/EDGE: 850, 900, 1800, 1900
Well the signal strength varies from time to time, I rarely get full network bars, usually is 2 or 3 bars. But I`ve noticed that in some places where using my HOX has full bars the ZL has one or no bars (by using the same sim card to be sure about the carrier and network strength). That is why I was wondering if there was a way to somehow change/add Radio Band on my Xperia ZL.
Please tell me when you try to change the radio band via *#*#4636#*#* does it show ONLY US Band or you might have more options to select? Please inform me, at least I want to know is it same to all Xperia ZL 6502 or just mine and those from US.

When going to *#*#4636#*#* and then phone information, it lists info for Data which is set to LTE in my case but nothing for Voice. You need to go to *#*#7378423#*#* >> Service Info >> Configuration to look at your Bands.
Mine are GSM850, GSM900, GSM1800, GSM1900. My phone is a C6506.
My signal indoors doesnt have full 5 bars either, it will be between 2-3 bars. Outside, ill have usually the maximum but sometimes 4. At my work I have 0 bars because of the building I work in but even with 0 bars my signal never drops. The bars are not perfect, they are just a representation of your signal more or less.
As long as your signal doesnt drop, I wouldnt worry too much about it unless you have real poor reception outdoors.
Sorry for the late reply
Mine bands are GSM850, 900, 1800, 1900 UMTS_BC1 BC2 BC4 BC5 BC8
What thoes this mean? I gont have compatible 3g bands for europian networks or something else?

You shouldn't have any issues with your phone. Your C6502 supports the proper frequencies which include pretty much everything apart from LTE. Only C6503 and C6506 support LTE. I don't believe you can flash a baseband to obtain LTE since it is also related to the hardware.
If you really feel like the reception is an issue, I would bring the phone back to where you bought it and have them verify with another ZL if the same type of signal is acquired by the phone but honestly, I don't think you have a problem.
But you be the judge of that....
Good Luck!
I thought also that i have the proper bands on the phone, but that`s why its so strange when using *#*#4636#*#* in the Phone info when selecting the 3 dots Select radio band ONLY shows US Band, I should be able to have more choices.
This is why I`m asking if you have the same option, or are there ANY Xperia ZLs that have more selective options than US Band only.
Thanks

I checked in my phone the *#*#4636#*#* and I I only have USA Band which I assume is normal for me since I live in Canada. But this information is for data reception (3G, H+, LTE) not for making/receiving phone calls.
The best thing for you to do is to walk in a store that has this phone on display and verify that its configured like yours so you know there's nothing wrong with yours.
for come back at your frequency you need type the code *#*#7378423#*#* and select the voice like "reset all customization".
The phone reboot and restart to work!!
Sorry for my english

That just does a total factory reset. Useless advice...
When receive a call, my reception is so bad i have to walk outside, for the other person to be able to hear me every time, my 4G internet basically wont work inside, I replaced sim card too. I don't have this issue with my Samsung Galaxy i9305 inside for calls or internet. Basically I can't use this phone it's not reliable, I've updated to the latest colouros then installed slimsaber, maybe the issues the "Baseband" tho updated colouros 2 times assume it changed baseband, definitely changed with slimsaber.
I'm using an Australian provider Amaysim, it uses the networks 700MHz, 1800MHz, 2100 MHz, 2300MHz and 2600MHz for 4G my find is the international x9006 version the box says it uses FDD-LTE Bands 1/3/7/20 and TD-LTE 40 this page on oppo describes the networks http://community.oppo.com/en/forum.php?mod=viewthread&tid=11921&extra= tho it confuses me, since b1 b2 ect each have 4 different frequencies listed.
https://en.wikipedia.org/wiki/List_of_LTE_networks
On there for Optus which is the network Amaysim uses, it lists FDD, Band 1 as 2100Mhz 3 as 1800Mhz 7 as 2600Mhz band 20 seems to be for 800Mhz which Amaysim doesn't use, and TD-LTE 40 is using the 2300MHz
So it would seem my phone supports all frequencies except 700Mhz which my i9305 doesn't have either, so it just seems to me oppo release phones with crap basebands for phone reception out of the box.
Appreciate any and all help with this.
This issue you're having actually sounds like a bad modem. Since SlimSaber is based on CM, you could try flashing ColorOS 1.2.7i, as CM works best with 1.2.7i, and then reflashing SlimSaber. You could follow a detailed guide to flash your ROM step-by-step by Oppo Community member fezode (kudos to him for this helpful guide for beginners). Google it as I can't post outside links yet.
Cheers!
