[Q] Cross flashing SGH-I337M with I9505 firmware? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I want to use my SGH-I337M in the UK - the phone is unlocked and I have a UK O2 4G SIM. GSM and UMTS seem to work ok, but I can't get LTE to work
Do I need to (and is it possible) to cross flash with a UK model (i.e. I9505) firmware?
Any help will be much appreciated.

You can't flash their official firmware, you can flash their ROM. I'd say check your carrier's LTE APN first, it may be putting in one that doesn't connect to LTE. Otherwise, your phone may not have the LTE band in it's radio, or it just doesn't like you ;P

The LTE configuration that O2 uses is:
800MHz, band 20, FDD​
The phone was bought in Mexico, and Samsungs Mexican site says:
LTE (700 / 850 / AWS / 1,900 / 2,100 / 2,600 MHz)​
However, the Canadian site says:
LTE Cat 3 (800 / 850 / 900 / 1800 / 2100 / 2600 MHz) * Dependent on market​
So I suspect the hardware supports 800MHz no problem, but perhaps it's not configured for that out of the box - do you think I would need to flash another ROM or baseband to get this support?
Thanks.

If you can make calls but not get data, I would say you have something going on with the APN settings, do you see an APN for O2?

Settings for Data in Dominican Republic

i jus't installed a new firmware from tabi13 in my elf, and everything is working fine, but the network detection seems to do an automatic detection of the settings from my provider (Orange Dominicana) and put some t-mobile settings
i just wanted to publish this information for any ROM builder if it can be changed in future releases, or for reference for other people.
Settings for Dominican Republic:
1
Orange Dominicana
Network Name: ORANGE
Network Number: 37001
APN: orangenet.com.do
no autenticantion or any other setting

Network Number: 37004 (Thanks Ajape for the confirmation)
APN: edge.viva.com.do
not sure about auth. I Believe is user and password 'viva' without the '
1900Mhz GSM
if anybody knows anything else, please post.if possible, for ROM cookers, update the auto detection settings in future releases (i don't know if it is possible or how)
Operator settings
There's one elfin ROM with the correct automatic settings for Dominican Republic it's and Opal based rom, not sure it's available for elf, I did notice the same problem with over 20 different roms for different models from wizards to tilts. can not recall the chef, on that particular ROM but it's there.
That's funny
The Onyx ROM which can be used in the ELF, mostly ELFin, but has run well in your model has correct Network Settings. I have personally flashed them for Orange as well, and it works properly. It is a ROM based from the updated ELFin ROM found in HTCs site.
Paul
Gracias for the information saved me allot of time.
Creo que viva es 37004.
Confirmed, 37004 is for Viva, although is registered still as CENTENNIAL DOMINICANA. 37003 is for TRICOM DOMINICANA.
Does anyone have the EDGE configuration for either ORANGE Dominicana or VIVA?
I´m using an HTC Kaiser, and would really appreciate them.
Edge
Just read the first line of this thread, it´s all listed there!
Thanks. My G1 didn't want to pick up my settings and this worked like a charm. I came to DR for vacation and was struggling trying to get my inet working.
The low down on Dominican Telecom's

Hi
I have a milestone a853 and i'd like to know if there a way to make it work on 3G
thats because i it only connect to edge thats in Santo Domingo
Orange dominicana is 900/1900 Mhz on 3G, don't confuse GSM with 3G frequencies, it's not the same thing.
Sent from my HTC HD2 using XDA App
I cant get any of my phones to work on 3g yet over the orange dominicana network! I have mytouch 4g and an atrix 4g... None if them get the 3g connection (mt4g is 900 3g and atrix 850) . Any ideas?
I will second (or third) the requests made above....
I was also in D.R. recently with my Tmobile Vibrant and couldn't get EDGE data connectivity with Claro to save my life. I went f***ng nuts trying everything. I had researched my phone capabilities ahead of time and found the following:
2G Network GSM 850 / 900 / 1800 / 1900
HSDPA 1700 / 1900 / 2100
From the posts listed above, Claro has 2G @ 1900Mhz. When I checked Wikipedia prior to my trip, it shows:
Claro Dominicana
CDMA 1xEV-DO in 800/1900 MHz
GSM/GPRS/EDGE in 850/1900 MHz
UMTS/HSDPA service in the 850 MHz band
Whiskey Tango Foxtrot?
Is there some kind of trick to get 2G data working? I am at a loss...I should have had 2G data (I knew I wasn't getting 3G), instead I was all sorts of lost without Google Maps. For the record...paper maps suck!
Someone PLEASE shed light on this situation. I am going back soon, I need data on my phone!
T-mo's 3G bands are not compatible with Orange 3G. The Atrix is not compatible either, however, theoretically you can use the Atrix with Claro's 3G since Att and Claro's 3G bands are compatible. I haven't tried this yet.

[Q] frequency on my GSM carier

hi guys
im from Israel..
i just got a new HTC aria device
i unlocked it with a code for any GSM carier for supported Israeli's network
now the phone is no longer under AT&T, it for Cellcom (an Israeli company)
the device support this:
HSPA/UMTS/(1900/850MHZ) GSM/GPRS/EDGE (Quad band 850/900/1800/1900MHZ)
Cellcom SIM CARD support this:
HSPA/UMTS/(2100MHZ) GSM/GPRS/EDGE (Quad band 850/900/1800/1900MHZ)
when i entered a regular sim which is for GSM only the device worked just fine..
but when i entered the USIM (the HSPDA's supported sim card - that suppose to support the GSM frequency as well) the device couldnt recognize any carier..
what should i need to do?
is there a way for changing the sim card frequency settings from the Android's settings?
do i have any possibilty for using HSPDA supported sim card without supported frequency in Israel?? because the device soesnt know the 2100MHZ HSPDA freq.
cause i thougt that device will handle this issue (works for calls) and will block me only when ill want to web through the Cellcom mobile in HSPDA
but still will let me to web through GSM witch is more slowly..
HeLPPPPP
i think you're out of luck unless you get the proper sim card for the proper frequencies.
Since Cellcom uses UMTS 2100, you would have been better off to buy an Asian or European phone. AT&T doesn't use the 2100 band and decided not to include it in this phone. You won't get 3G on that carrier.
According to Wikipedia, another provider - Pelephone - has some of its 3G service on the 850 band which would be supported by the Aria. But in any area that is served only by the 2100 band, your Aria will not get 3G.
No idea why one particular SIM isn't letting you onto their GSM network.

[Q] Does the European Optimus 7 supports WCDMA 850?

I bought an European Optimus 7 and it shows on the box "WCDMA 900/1900/2100, GSM850/900/1800/1900"
There's any way to put this phone to work on 3G WCDMA 850 networks at full speed?
Thanks
I own a Telus version of Optimus 7. My phone has the 900 3G band on it. I will tell you how to check whether your modem supports 850 or not. First, you open up the dialer and enter ##634#. This will install the MFG app, that will be accessible through your app list. The password that it asks is 277634#*#. Now you have access to the manufacturer test/setting menu. Proceed to the Engineer Menu, and then Modem Setting, followed by Band setting. There, you should see all the bands that are available, and WCMDA basically means UTMS or 3G. If you have the 850 band, it should be available in this menu. There are two other things you need to do before gaining access to this band, if available. But in order for me to continue, I need to know which carrier you plan to use this phone on. I am going to assume you want to use this in North America and you have already unlocked it. Let me know, and I shall help you further on making your phone functional for a 3G connection. BTW, I am typing this on my Optimus 7...the keyboard is seriously great, and if it wasn't for the loose buttons, I would have absolutely no regret over my purchase.
Thanks.
I saw here, there are these options available:
1.Automatic
2.WCDMA Only
3.GSM Only
4.WCDMA 850
5.WCDMA 1900
6.WCDMA 2100
7.GSM 850
8.GSM 900
9.GSM 1800
10.GSM 1900
11.WCDMA 900
Sorry for picking up this old thread again but there is no final answer on this.
The point is that I'm having the same problem, I have a european E900 and I can see the WCDMA 850 in the MFG settings. So is this working?
I'm going to Thailand next week and wanted to use True Move 3G which is on 850 Mhz.
Ok, just for the record - I am in Thailand now and the 850Mhz 3G Network from True Move is not working on the European E900.
Hope this helps for those who were looking for this answer.

[Q] LTE Bands supported by UK LG G2 (D802)

Does UK LG G2 (D802) support LTE Band 20 (800 MHz) used by O2 UK?
Does anyone know this?

1) Go to Phone, just enter following command,
*#*#4636#*#* (no need to press Green Dial Button after this).
2) Once you enter last *, Testing menu will appear. From that menu,select "Phone Information"
3) Scoll down little and you will see "Set Preferred network type". There is dropdown at this location which shows all the networks.
Just note,This is testing menu. It will show all the options like CDMA/WCDMA, GSM, LTE etc. It does not mean that all the networks are supported.
Just insert LTE sim and change option of preferred network from above list to LTE only and check if that works.
Officially it supports 850, 900 bands. But I am wondering if the bands are only controlled software side seeing that the antennas and hardware seem to be streamlined across all versions.
On the box it says:
LG-D802
LTE 2100/1800/2600/900/800
6GB
BLACK BLACK
Thank you for the test menu you solved my problem I just bought the d802 would not work on my 4g sim in uk changed to lte and all good thanks.
Sorry to bring this one back form the dead but the original question doesn't appear to be answered to me...?
I am on Three in the UK and they are rolling out 4G on 800Mhz and 1800Mhz. Complete noob here, but from what I have read 800Mhz has greater range and building penetration (at the expense of some speed), which is great. Except that the G2 doesn't actually support 800Mhz LTE, or does it?

I found and downloaded the free app 4G LTE Switch from the play store to help with this.
While it doesn't solve the problem of having to manually select LTE after each reboot, it saves you from having to dial the code yourself. Instead, just launch the app and it takes you right to those settings. I find it very useful and time saving! :good:

cheers for the heads up, i'll give it a bash, still find it very strange that a 4G phone doesn't come with an easier way to actually activate 4G.

No problem man. I didn't give up searching and actually followed this thread, where it says "No 4G/LTE?" and tried putting my networks actualy LTE band (17) in there instead of 11 and 13. While it now gived the option of selectiong LTE in the dropdown menu of preferred networks, for some stupid reason, the phone STILL doesn't save the setting and you still have to go back to the menu again after a restart to enable LTE.
While it is even easier than the method I said earlier, still frustrating that even after selecting it in the menu, that it still defaults back to GCM/CDMA!
There just HAS to be a way to make this stick. Any devs out there who could look into this further???

Hello,
I am from Portugal, so your mobile could say something rather different. But in essence is all the same.
My version is the D802, International model, just like yours.
1.st step - Provider:
The provider part is always the first to be deal with.
Make sure you go to your operator and ask to enable your SIM-card to have access to LTE.
2.nd step - Equipment:
Go to Definitions -> "Network" tab -> "Sharing connecting & Network" on the bottom -> "Mobile Network" third from last ->
a) Make sure that "Enable Data" is checked;
b) Go to "Network Mode" and choose the option: "GSM (2G) / WCDMA (3G) / LTE (4G) auto".
This way you will always have automatic access to the best network available.
All the people who choose the 4G/LTE only option should check this mode, so you can access 3G when 4G is not available, instead of having no connecting.
Any doubt you have, just ask!
Best regards.

Step 2 in bold, that's not an option. 3 options are
1. GSM / WCDMA auto
2. WCDMA only
3. GSM only
However when using the 4G switcher app you can change it to GSM (2G) / WCDMA (3G) / LTE (4G) auto and it works fine, but on reboot just defaults back to GSM / WCDMA auto.
Our D802 supports 1800 Mhz and 2600 Mhz frequencies for sure.
But to get the LTE toggle to show up in the network selection menu, we need to insert a LTE capable sim or usim. Tried and tested and not a here say.
If you do not get LTE option in network selection then your sim is not LTE capable. Simple.

The option in my phone is:
"GSM (2G) / WCDMA (3G) / LTE (4G) auto"
All this information at one option.
So the phone can choose the highest band level.
This is a problem with your ROM or a problem with your SIM.
And, as I said in my first post, go always first to your provider and ask him form help.
Making sure the SIM part is enabled and fully accessible.
The bands are not important here.
That is because, if you bought your smartphone in the UK, LG made available the D802 model to make your smartphone antenna frequencies correspond to those available at your country.
This will matter if you want to achieve maximum speed of 150Mbps.
But if you want just the regular user experience, you sure have access to LTE network.
In wikipedia (I could not find a good source, as GSMArena make no reference on the version D802)
Wikipedia -> LG G2 -> Specifications
D802 supports 4G/LTE bands:
800, 900, 1800, 2100, 2600
And here you can see the bands of your provider/network:
Wikipedia -> List of LTE networks -> Europe
EE: 1800, 2600
Hutchison 3: 800, 1800
O2: 800
UK Broadband: 3500, 3600
Vodafone: 800
This is wikipedia information, so take this with a pinch of salt, and search for a better source.

Its a UK sim free handset, and i'm on tesco (which is O2).
Sim card is fine as tested in another 4G phone and defaults to 4G as it should after collecting the APN settings from the network. Checked the APN and both the exact same compared to the one the LG G2 is using.
I'm using stock rom and this happened initially on JB, then updated to KK, factory reset, and still the same, then updated last week, still the same.
From reading this thread looks like i'm not the only one.

Wikipedia, and other websites, say O2 only acquired 800MHz band for LTE.
And LG G2 D802 only supports:
850 (band 5), 900 (band 8), 1800 (band 3), 2100 (band 1), 2600 (band 7) MHz.
I saw this at PhoneArena, GSMArena and ATGSM.
This brings a problem for people which their carrier only emits LTE at 800MHz, when not supported by come smartphones.
But I recommend you all to ask LG about the frequencies supported by the LG G2 D802 version, and ask your network carrer/ provider for LTE frequencies.
That way you will be absolutely sure about its compatibility or not.

wikipedia is saying....LTE band support 800/900/1800/2100/2600, however tesco (o2) are definitely on 800mhz, so must be something to do with LG so it will no doubt be them who has to answer the question, and never do anything about it.

Flashing AT&T ROM to another carrier

I was wondering if anyone has successfully flashed an AT&T rom to another carriers device, specifically a Verizon galaxy s4. I was told to try it but I wanted to know if it's been done before.
Is the bootloader on your s4 unlocked?

No it is not.
That's good. However, flashing an i337 ROM onto your phone may result in a hard brick. I don't know about the partition layouts on i337 vs version s4.
With an s3, cross-flashing custom ROMs from an international s3 to a North American s3 will hard brick the North American s3.

I think mine is an international version. How would confirm if it is or not?
Is the Verizon s4 a cdma phone with an 3g/LTE sim slot? Flashing an AT&T ROM to your phone may disable phone calls and data as the AT&T ROM requires a specific bootloader and radio frequencies to work. It could also hard brick the phone.
If I were in your position, I would find out how to flash a custom ROM before attempting to flash the AT&T ROM.
Any particular reason you want/need the AT&T ROM?

My phone has CDMA and GSM network settings. I am using this phone on AT&T because I cannot afford to buy a new one right now. Everything works except sending sms on a LTE signal. Fails every time. If I switch to HSPA+ I can send sms but being on this signal causes my battery to drain really quickly for some reason. So I'm trying to sms to work properly on a LTE signal. Someone suggested I try flashing a AT&T rom to my phone since it would most likely have the correct sms files which he believes is why sms doesn't work properly while on a LTE signal.
I understand. Are the APN settings the same for 3g and LTE?

Yes they are
I did a quick search and found this:
Does your mobile web work? mms uses mobile data and standard text messages do not. I have had mobile data take up to 2 days to work on a new activation you stated you took the apn settings off the att site but I just thought I would post what is on my phone just in case it may be different
Name: ATTPhone
apn: Phone
mmsc:http://mmsc.mobile.att.net
Multimedia message proxy: proxy.mobile.att.net
Multimedia message Port: 80
mcc:310
mnc:410
apn type: default:mms:hipri
both standard and roaming protacols are ipv4
everything else is not set also try turning mobile data off then back on.
also make sure that the phone is in global mode

Yeah everything works except send sms. I can receive sms all day but it fails to send. I can send and receive mms, make and receive calls and browse the web. It's just send a standard text message fails every time. Those are the same APN settings I have currently. And it's not a new activation. I've been trying to figure out a solution to this for about a month.
international version has better roms than any other carrier ....... am using an s4 att version with international carhdrom 4.4.2

The reason it isn't working on LTE is because the Verizon S4 only supports 2 LTE bands and does not have all the LTE bands needed for the AT&T network. There is no way for you to use the LTE network fully and get SMS to work. This is a hardware limitation.
US GSM (AT&T - Model: SGH-I337):
GSM/EDGE: 850/900/1900/1800 MHz
UMTS/HSPA+: 850/1900/2100 MHz
LTE: 700/850/1700/2100/2600 MHz
US CDMA (Verizon - Model: SCH-I545)
CDMA EV-DO Rev. A and Rev. B: 800/1900 MHz
GSM/EDGE: 850/900/1800/1900 MHz
UMTS/HSPA+: 850/900/1900/2100
LTE: 700/1700 MHz (Bands 4, 13)
I have not personally needed to do this, but you can modify your "SMSC" preferred network type from "LTE/GSM" to "GSM Auto" which should route all your SMS messages through HSPA+ instead of LTE. Therefore, you can use your phone on LTE (calls/data) like normal but the SMS will be HSPA+.
Root device if you arent.
Install Advanced Signal Status
Hit "Additional Info" in the app and then "Phone information".
Change dropdown for "Set preferred network type:" to "GSM Auto".
You can hit "Refresh" button and it should show "+13123149810" for AT&T otherwise change it to that for AT&T.
Restart phone.
Hopefully that works!

Actually I can activate all the LTE bands through one of the hidden menus. But when I do it still doesn't work.

That is because the Verizon S4 itself, hardware wise, does not support all the bands AT&T uses (like band 17). There is nothing you can do to make your phone work on network frequencies that your device doesn't support, no software can change that.
Sorry.

But in the service menu I have it shows all those bands and gives me the option in which ones to activate
