[Q] [SOLVED] Changing Frequency Band

Hey all,
I just moved to France with a i9020a Rogers phone. According to this (http://forum.xda-developers.com/wiki/Samsung_Google_Nexus_S) my phone can cover the 2100 frequency band and according to this (http://www.worldtimezone.com/gsm.html) France's 3g frequency is 2100. I just got a SIM card and my text and calls seem to be working, however, I can't use data at all. Any ideas?
Phone info:
Type: Rogers i9020A
ROM: 4.0.3 stock
Kernel: eugene's
Radio: UCKE1

I tried following the steps below, however, after deactivating and activating my phone radio and pressing menu my phone just went back to the home screen. I remember doing this with gingerbread and having a new screen asking which country and provider I had. Can anyone else do step 5 with ICS?
1. Go to Dialer. Dial *#*#4636#*#*
2. Go to Phone information. Choose the preferred network to
"GSM Auto PRL" or "CDMA Auto PRL" or whatever you have.
3. Scroll down, deactivate and activate Phone Radio.
4. Press Menu button.
5. Select Phone frequency, then choose your country.
6. In the previous menu push the Home button to go back to Homescreen.
7. Reboot.

Gotten edge working
Update:
I have tried flashing several different radios with no luck. I did find that I did not have any APN settings so I found the APN settings for my provider (http://mobile.free.fr/faq-config-apn-autres.html) and now I have EDGE .
Since I can only have one APN configuration selected at a time how do I configure the MMS to work? Will configuring it under a new configuration work or do I incorporate it into my current configuration.
And of course I still can't get that blasted 3G to work.
Any help would be appreciated!

Solved:
After flashing my original radio (UCKE1) on my phone my 3G is now working . To configure my MMS (for free mobile anyway) I used the APN settings provided by Liel (http://forum.xda-developers.com/showthread.php?t=1452220). I hope this helps anyone who's having trouble in the future.
Cheers!

[Q] 3g issue

Hello there, i just got this phone 3 weeks ago and since i have wifi i didnt test the 3g conection before. i activated a data pack and i just realized that my 3g doesnt come on at all. the screen shows 4g left side of the signal strengh but it doesnt work at all. i got at&t version. i confirmed with my carrier and i did activate data, they even helped me to set up the apn but is still not working. can you helpe me? thanks!
PD: they said they couldnt have done more because they dont support that type of device

Does it say 4G or 4G LTE? The at&t icons are a bit different I'd you're not used to them.
4G = hspa
4G LTE = LTE
So if you're getting the 4G icon you are actually getting 3G hspa speeds.

If another carrier besides AT&T, you will need to find the APN settings for your carrier and manually enter it into Settings>Mobile network settings>Access point names. Select "New APN" and enter the correct settings for your manufacturer.
The 4G icon simply means a network is present, it doesn't mean you are connected to it.

thank you for helping people. whel actualy i wouldnt mind getting 3g network access, the point is that i dont have internet access at all. i called my carrier (Claro - El salvador) and they helped me to set up the apt but is still not working. i was wondering if there is something else i could try to fix this

nevermind, i finally fixed it

Please share the fix so the information is available for anyone who might have the same problem in the future.

sorry. well, first i did master reset, once done i set up an apn (carrier provides you with this info), then went to mobile network > network operators > select automatically. once the device found the "CLARO" network i turned data on and got internet service.

Thankyou, these threads live on long after we're finished with them so it's important to have the information readily available for future troubleshooters.

I'm guessing you either had not entered the APN info exactly correctly the first time. Or also, after entering the APN you actually have to select it as the "active" one on the list of APNs (making sure it has the colored dot next to it). Maybe it did need a factory reset, but this shouldn't be necessary just to change APN.
Happy you got it figured out.

SM-G920W8 | No Option To Connect to LTE

I bought an Unlocked Canadian S6 recently, and it just won't let me connect to the LTE network.
Model Numer : SM-G920W8
Android Version : 5.0.2
Baseband : G920W8VLU1AOCG
Connecting to the LTE is not even an option. When I go in the Network Options, I get the choice between :
-WDCMA/GSM (auto connect)
- WDCMA only
- GSM only
I know for a fact that I am in the coverage zone, so no need to ask that silly question
I've tried different SIM cards, played in the options a bit, and factory reset the phone about 5 times now, yet nothing seems to work.
Also, when I try to do the update, it just reboots and gives me an Android logo and a failed Icon
I've only seen one other post like this from a carrier's support website, but no solutions were found.
**Update : For a reason, after a recovery, it will connect to the LTE for a bit or until next boot, then go back to what it is now.

First question, who did you buy the phone from? Second, Is it second hand? By default, Wind mobile does not allow the LTE option to be displayed in system settings as they as a carrier don't have LTE. It is blocked by the CSC setting for the carrier. As for other carriers It should leave you the option to connect in settings where you say it is not. If it is a Wind phone, You would need to change the CSC to enable the LTE selection. There is a method to force LTE even without option in settings, but I think it is removed in the latest firmware. Try dialing *#2263# in the dialer. It may bring you to menu that will allow you to select LTE. This is not a permanent method though as it will need to be done every boot. The other way, (If you are in fact a Wind/Mobilicity phone) is to enter dialer and enter *#272*IMEI# with IMEI being your devices unique code. If at all possible, take a full nand and Titanium Backup before doing this and be sure to transfer everything off the phone to a PC. This method wipes everything and I mean everything off the phone buy is a surefire way to enable LTE.

Yes, it was second hand. I didn't ask who was his carrier simply because it was unlocked.
I'll try it tomorrow, thanks for the information

Here is the menu you will see when you type the *#272*imei# code into your dialer. The codes are the carrier names. Mine which is GLW is Wind, BMC is Bell, RWC is Rogers, etc.

Maybe there is no LTE in your area...

It would still be visible in the Settings/Mobile Networks/Network Mode menu which it is not. His problem is more than that.

Sweet! It works :good: Thanks man
Now, would you have any ideas on why the update won't work? I didn't get much into it yet, but I will soon.

I'm not sure why it wouldn't update, but now that you have changed the CSC you can download the update and flash with Odin. Pick your carrier and go to town. The guy running the following thread runs his own firmware host. He's got amazing DL speeds. Usually takes me 6 or so minutes to do the 1.6gb file. http://forum.xda-developers.com/showthread.php?t=3086387

I'm having the same issue.

Connected with someone selling a G920W8 version. LTE is disabled and the codes aren't working. Can you reaffirm which unlock code worked for you? I'm on Fido, what LTE network are you using?

hi BCSC
Thanks for the details. I searched complete net and read all articles but nothing set me up with the proper thing. i read your solution i dialled *#2263# and all i got is service mode and in that i went to band selection , LTE and the all ....... Yes and its showing LTE in mobile data. THanks so much.
But now another issue, network is showing perfect but no outgoing and incoming calls.
in incoming its showing busy and on outgoing its not connecting to another phone.
And, Lte is not showing in mobile networks, There only 3 options still are showing.
Mine is same Wind S6 but i had to use in India.
Let Me know
Thanks once again
Cheeerzzzzz

Picking LTE from the service mode will note make it visible from the settings menu. Its more of a workarpund instead of a way of permanently enabling it. As for the issue of no out/in calls, my best guess is that it could be due to which LTE bands are being used or are available in India. Unfortunatly I have no way to test that option. I only was successful in getting the Wind LTE option on Canadian carriers.

Please help! No 3G or GSM, can't call, but LTE works fine.

I really need help with my device, I searched all over XDA and no-one seems to have the same issue as me.
Here is some information:
1) Nexus 6P (H1511)
2) 6.0.1 Absolute stock, no rom, no root, no custom recovery. Build number MMB29P.
Recently got a new Nexus 6P and imported to Russia. All of the major bands here are supported. And the phone worked excellent for a few weeks, but then it lost all 3G or GSM connectivity. Just randomly,didn't do anything with it, the only thing I did is move to another city but than I got back, the issue didn't resolve. LTE works perfectly but can't call or receive calls, can receive sms though. Reseting network settings and factory reset changed nothing. Tried manualy set network to WCDMA or GSM with *#*#4636#*#* command, the moment I switch to anything besides LTE the connection is lost. Contacted the provider, no problem on their side, my SIM works good in other phones, my phone with other SIMs - no.
I don't think it is a hardware issue because a few times I managed to get everything working after an hour of switching networks and bands with no particular order in the *#*#4636#*#* testing mode.
After a while I figured that if I set phone to "GSM only" on USA bands in testing mode, but at the same time set it to "LTE prefered" in the normal network settings menu. I am able to set phone to Band mode 7 and set the network back to 2G in network settings keeping it on " GSM only" the whole time and only after this compicated algorithm and after a reboot 2G and 3G starts working. But any reboot after that revertes everything back to only LTE stage. Also if I get everything working but than reset network settings everything stops working again.
I have no idea what caused such an issue, I really hope someone can help.
Sorry couldn't post screenshots because of the "10 posts rule".

Lg g4 h810 works 2G only

Hi,
I bought this phone Lg G4 h810, it shows AT&T logo whenever i boot it and the problem is despite of network mode on lte/wcdma/gsm/auto it always runs on2G internet speed and shows E sign.
I am from india and many service providers are still not offering4G internet service. But this phone doesn't even runs on wcdma. My previous phone lenovo was nicely running on wcdma and always showed the sign H.
My cellular operator is idea cellular and i had a word with them, they sent me settings and all and help me input the settings manually too, but nothing worked.
I checked even the frequencies, idea cellular is offering UMTS B1(2100) and UMTS B8(900 gsm). I checked this on LG website and these bands are compatible with the phone i bought, but still i can't get anything more than2G. Why so?
Plus there is one more problem, when i switched it on for the first time it showed update available And when i tried to update, it showed error and now always there's an icon on top left corner of phone saying couldn't install system update. I tried restarting and updating the device many times, but it's still the same.
Any help is much appreciated.
Thanks in advance.

Have you put your Company APN?

Yes i did, the company executive even helped me to manually save the settings to run the internet in a 3G mode. But all efforts in vain.

Did you solve the issue?

Anything new? I have the same problem.

I have this problem too

Try hidden menu with *#546368#*810# and under Field Test menu / Modem settings if there is VoLTE on/off chose VoLTE and restart. I have done that and my phone starts working with 4G. Don't forget to set up good APN if it's not automatically set by network provider.

Hi
Under VoLTE there is another entry named "Session" and in there
RPR(on/off) switch
I enabled it and restarts but it is again on 2g
Anyone further on this issue??

I have this problem too
I was flash the stock firmware,custom firmware customizing the build.prop,changed the settings in the engineering menu *#546368#*810# disconnected volte,changed LTE bands forcibly. Nothing helps,dont work 3G LTE - 2G only(. I realized that I need to re-flash (change) the original QCN file for H810 and re-register IMEI , but I can not find QCN it freely available.

Hello there, i had the same issue. The fix that worked for me was searching for network manuallly and reconnecting again to my carriers LTE network. Worked as a charm. The issue maybe was a brutal handover as I had been travelli g from a city to another one 200 km away. So somehow I had been disconnected from the LTE network and left stranded in the 2g one. Try it it should work
