Changing 3g frequencies?!?! - Optimus 7 General

Hello!
Congrats for this community!
I have a problem and I cannot find the answer on internet:
Can I change the 3g frequency of my LG P705 optimus l7??? How can I test it?
I bought it in China and I'm from Argentina, here the frequencies are 850/1900 MHz, different from the frequencies used in China. I coudn't found information about it! It is factory-unlocked and it has Android 4.0.3 by default.
My cell phone is not usefull without 3g, I can connect to 2g or to Wifi networks but I need faster communications all the time.
Thanks and many thanks!

same as me but need it for Mexico (telcel) trying to get some different firmware but i'm still not so sure to do this with out knowing all

Network problem with Blackstone

Hi I would like you to help me with my network settings.
I'm from Mexico city and I bought a HTC Blackstone few days ago. First of all let me tell you that in my country we don't have a provider for HTC phones, we just have some of them but the old ones. So I bough my Blackstone from a US online-store.
I did Hard SPL on my phone and installed Laurentius26 "L26_THDV5" ROM. After that I took some time to configure the network settings from my country and everything was ok. But my problem is that my Blackstone is not working on 3G mode, it's using EDGE. Actually I don't know how far the differences are, but I can feel that it's slower with Youtube or Internet than my previous phone (a Nokia N75). I don't know if I changed something with the new ROM or if there is some way to fix it and work on 3G mode because actually I'm paying that service with my provider (Telcel).
Please, could someone help me with it?
The Nokia N75 supports the 850MHz / 1900MHz 3G bands.
The HTC Touch HD supports the 900MHz / 2100MHz 3G bands.
Depending on your provider you will not have 3G at all.
are you sure ?
I've started a thread about this:

[Q] Differences Between E900 & E900h

Guys, anybody knows if really have any "real" difference between the E900 and E900h versions?
I am asking this because I own an Orange-FR E900 and as widely said, this version doesn't support UMTS 850. Even in the box of my handset only shows "WCDMA 900/1900/2100, GSM 850/900/1800/1900".
But I never had any problem using it anywhere I went in the American continent, even before I flashed it with the Open-EU ROM.
With the original French ROM, I had used it both in 3G and 3G+ successfully here in Brazil with Vivo, Oi and Claro SIMs (all UMTS 850/2100), in Argentina with a Personal Telecom SIM (UMTS 850/1900) and Canada on Fido (UMTS 850/1900).
Now with Open-EU ROM and the Tim SIM (UMTS 850/2100), I performed a simple test on Band Settings. With "WCDMA 850" set, I got the "3G" sign at the Status Bar, and with "WCDMA 2100" I got the "H" sign that replaced the "3G+" from the previous ROM.
So I'm guessing what is the deal here? Luckily I got one "factory all-unlocked bands" or all those "Euro-Spec / American-Spec" thing is just bs they told to us to avoid "bootlegging"?
Where did you get the OPEN EU ROM?? I can't find it.
As you know I am having problems connecting to UMTS 850 here with Claro Peru and I think is due to a software (ROM) lock or stuff like that and I wanna re-flash my phone E900 using the OPEN EU ROM.
Please, give me the URL to get the ROM. Did you get some issues with the new ROM? maybe camera or marketplace access?
Thank you

I got the ROM and all instructions here: http://forum.xda-developers.com/showthread.php?t=935578
I recommend you to read the entire thread before flashing your device. Information is never too much
PS.: Don't try to flash your E900 with an E900h ROM (and vice versa). If you do that, you gonna brick your device.
There are actually very minor differences, between the two. I have yet to compare actual parts models, but here are the sevice manuals, with all individual components teared down and outlined. Take a look, perhaps it would clarify something. The manuals are very long, of course.

Hi, I just got an E900 (It was a gift) I can't get a 3G signal in Telcel's (México) Network which uses a 850/1900 band. The phone is OPEN, is not locked in any form and came from factory with Mango.
I have tried all the possible band configurations through the MFG app but can't get a "3G" signal. Here is the question, is there any possibility to get the phone to work with Telcel's 3G Network or Am I wasting my time?
Best Regards

You are wasting your time, you need an e900h to get UMTS or 3G on the 850mhz band.
I've got both an used unlocked Vodafone E900 (carrier still says Vodafone - how do I get it to open) and a brand new Telus E900h with me and can't decide which one to keep.
E900H will have to be unlocked and it's asking me for PIN right now. But it has 850 signal and since I'm using Tmobile US with it I should be able to get 3G. With the E900 I'll only be able to get Edge on T-mobile unless if I switch to ATT but they're pay as you go plan isn't as nice.
But it seems that you aren't able to get internet sharing to work on E900h since Telus hasn't released it. That option is available to E900.
Are there any other differences? Which one should I keep? I've a tendency to lose phones but I don't think I'll want to keep both around.

[Q] SM900F Baseband Question/Problems

Hello ,
I bought a SM900F from UK a while ago and it was unlocked. I was capable of using 4G network there easily with no problems, but recently I have come to Dubai and am not able to hop on the 4G network . I have checked all the settings and made sure I had the 4G sim/ 4G data bundle and so on , but still same problem.
As per Wiki : Etisalat United Arab Emirates 1800 3 FDD September 2011 [500]
Etisalat United Arab Emirates 2600 7 FDD September 2011 [520]
My operator provides 4G on 1800 and 2600 Frequencies which are supported by SM900F. Just to clarify , this unit had never been locked .
So now im sitting here confused on what I need to do to get my 4G working , Im always connected to H and H+ .
Thanks in Advance ,
Nylem
Try to ask operator to give you his APN settings!
Settings - more networks - mobile networks - ap
Thanks for the reply ,
I have done that but still no hope

Your phone should support those LTE bands.
Confirm that the band /frequency information isn't outdated.
Are you in an area where the carrier doesn't have LTE coverage?
Open a support ticket to investigate if the carrier has provisioned your account /SIM correctly for LTE.
Look at the various online forums and find out if others are getting LTE in your location.
Set what the LTE signal strength is in the S5 service menu.
Set a preference for LTE in the service menu.
Possibly you are getting 4G, bit the onscreen icon is just incorrect?
Try updating or changing your 900F modem.

Thanks for the swift response mate ,
1) Band/Frequency are all compatible with the phone
2) The whole city is LTE covered ( specially mine that I live in the center ) .
3) Already working on a ticket with the carrier , but they say problem is from my side
1) I set the LTE Signal , Lost all connection
2) I put bearer as LTE , Lost all connection
3) Could be a possibility
Can you kindly forward me or show me the path to where I can change my 900F modem to a more international one , Thanks a bunch !

Something is probably misconfigured or misprovisioned. But regardless, the issue will only be solved by paying attention to details and a process of elimination (of the possible causes).
The most productive single thing that you could do at this point would be to borrow a known working LTE SIM from a neighbour and see if works in your handset. Whatever the result, it would narrow down the possible culprits.
Also, don't assume that the frequencies are correct. Confirm with the carrier that they haven't changed or added new LTE bands.
Make the effort to find out what forums your carriers' customers usually frequent and look at recent posts there for seredipitious insights that you won't find elsewhere.
Don't dismiss the icon idea out of hand. Are your speeds indicative of an LTE connection?
You don't need a more "international" modem. Just a more current 900F one. Or less commonly, an alternate or older modem if your current one has a bug. Do a forum search for threads about changing modems. There are a lot of them. Don't fixate on this - it's one of the least likely possibilities.
Also consider updating to Android 4.4.3 or 4.4.4 which is said to address some connectivity bugs.

[Q] LTE is not working

Hi, I got the S5 SM-G900F few weeks ago and all the time it was trying to figure out how to turn on the LTE.
There is option for it in settings but it doesn't connect to LTE either way, so I did a little research and found something about changing band selection mode, but that didn't work for me.
I have original 5.0.0 rom. I have virtual carrier, which is using O2 network. 1800 MHz 2600 MHz 800 MHz are the only LTE bands used by this carrier in my country and I know the coverage should be fine because of my friends can use LTE with different phones on same network.
I only found one solution which I didn't try yet, because it requires rooting the phone, which I would like to avoid for a bit, because this is my first phone with android ( Sounds almost unbelievable in this age, right?) and I would like to learn to use it well enough first.
So if you guys could suggest me any possible fix, I'd be really gratefull.

Meizu MX5 no 4G network capabilities

Hello,
I have been using my Meizu MX5 for about two months now without the 4G network working. I have recently updated to the latest firmware and I am currently running Flyme OS 4.5.2.7A and that has not solved any issues either.
I have checked that the phone settings are configured properly.
Network Mode is set to "4G First".
The phone is pending between, H-, H and H+ connection (3G I believe?)
I have checked with my provider and these are the following frequencies which should be providing 4G in my country (Sweden) for the provider:
800Mhz, 900MHz, 1800MHz, 2600MHz
Other providers have the same frequencies as well.
I have also gotten two new SIM-Cards during this period of time without it solving any issues. I have tried the SIM cards in some other phones and they get 4G connection without any issues.
I have been in contact with Meizu customer support in China and after some random troubleshooting of factory resetting and reinstalling the same firmware on the phone without solving anything.
They have also provided me information regarding the different bands/frequencies which the phone operates on:
GSM/GPRS/EDGE (900/1800/1900MHz)
WCDMA/HSPA+: Band 1/2/8 (900/2100MHz)
FDD LTE: Band 1/3 (1800/2100MHz)
TD-SCDMA: Band 34/39 (no freqency specified)
TD-LTE: Band 38/39/40/41 (no frequency specified)
I am not 100% sure on how this works but according to the information I am given, the phone and my provider share at least one frequency for the 4G network and therefore I do not understand why it is not working.
I am sure that it is software related and thus I won't send my phone back to China (4-8 weeks delivery time and all expenses has to be paid by me) for them to troubleshoot.
Anyone here who has knowledge which could give me an answer?
Kind regards,
Martin
Hi mate.
I had this problem but upgraded to new firmware late last night and it came on. Thankfully!
Give it a try
Hi,
I have checked the upgrade app on the phone and it says I have the latest firmware.
Which firmware version are you running?
Kind regards,
Martin
Maybe it is an APN related problem. Look if you have the same data as in the other phones that 4G works

Hi iicc,
Thank you for the reply.
I have checked the APN settings about four-five times and I can't find any inconsistencies. I have even crosschecked it with a support technician from my provider.
The only things I can think of is either my anntenna being gimped, that the firmware is not properly developed or that somehow there's trash in my system and that my phone maybe needs a complete wipe and reinstallation.
After the upgrade to firmware 4.5.2.7A the phone does not even hint on trying to connect to 4G. Pre-upgrade it atleast connected to 4G for about 5 seconds and then went down to 3G.
Kind regards,
Martin

Let me try to come up with something that might be your problem. If you are using 3 as your mobile provider then they use FDD-LTE band 7 & 20 none of which are supported by the MX5 and 3 are also using TDD-LTE band 38 which is supported by the MX5, but might not be available in your area.
If you are on Net4Mobility then they use FDD-LTE 3,7,8 & 20 of which only 3 is supported, so it could that in your area there is no coverage with band 3.
If you are on Telia, the story is pretty much the same as Net4Mobility as they use FDD-LTE 3,7 & 20.
In order to get more from your phone. You can open up google and search for 'meizifan eu' and go to the website. They have a pretty good description of how you install the international version of FlyMe on your MX5, the international version is called 4.5.2.7i. I believe it activates some other FDD-LTE and TDD-LTE bands.
1800Mhz band is a short range, higher bandwidth frequency which usually is less common and given that it has a short range it most likely isn't available in your area.

Thank you for the reply nasty_suicide!
I am using Comviq Tele2 as provider, which should use the Telia net.
This is what I believe as well, but I really thought there was no way to flash the international version onto the phone and was about to abandon ship by buying a new phone yet again.
I will try to install the International version as soon as I have time to follow through the steps. I have found the guide on Meizufans.
Once I have installed the international version I'll let everyone know the outcome.
Kind regards,
Martin
Hi Hawdes,
I've exactly the same problem as you do, please post back once you instal I version. I was planning to do so but since I already have everything installed I didn't want to go through trouble for nothing.
What were the results of this? Is it true that firmware can affect the signal received?
upgraded to the latest firmware yet?

What about in Samsung galaxy s7 version of Flyme OS?? I cannot see 4G option.
