Hi,
I have SGH-M919V and its unlocked.
I am on Bell and want to use LTE. But this model has LTE disabled. when i enable it, cant make phone calls.
I cant seem to flash T mobile modem via odin. there is this secure boot issue. the AUTH: Fails.
I was thinking of installing Bell SGH-I337M rom on my phone. Is that possible? If so, how do I go about doing it?
Thanks!
Since you have a T-Mobile variant you should ask in the sgs4 tmobile forum...
However your problem with lte/phonecalls is likely just an APN issue
To further assist we would need to know which carrier you are using the device on

Hey. thank you for the reply, I really appreciate it.
I've been asking a lot there. No one is answering.
Please help me out, please.
My phone is Canadian variant, originally from WindMobile - SGH-m919V. Wind uses Tmobile freq. = 1700/2100 (AWS) only. No LTE.
I got it unlocked two days ago, and switched over to Bell carrier. Bell uses the other freq and LTE.
When I do force LTE by *#2263# - and enable all LTE, i get LTE speeds. But NO calling or texting. this is with the original Windmobile stock rom. No modification. No root.
I tried to flash Tmobile modem via odin 3.07, didnt work. I used the phone button to load the modem.bin. It gave me AUTH: Fail, secure check fail.
I agree, wrong forum, but we are here to please....
if you have a M919V then you would flash the rom you want, before you boot, flash a tmo m919V kernel, it will boot, manually add your apn settings for your device, it will work with data/wifi/calls.
Good luck....
Hi, im sorry for posting in this forum.
so if I want to flash the bell rom - I337M stock original rom , how do I flash it without booting??
And then how would I flash the tmobile kernel so then I can boot??
I dont mind keeping my current rom - wind stock. But, I want to be able to use LTE like how tmobile has pentaband 3g plus lte.
:/ .
A friend of mine got a Sprint S4 but he wishes to use it with a GSM Carrier.
First couple things I noted are:
1) No SIM Card Contact Management, had to use an App to copy all to phone
2) Cannot find GSM APN settings to manually enter
Is it possible to flash a stock International i9500 ROM over this to alleviate the issues with using a mainly CDMA version?

I do not believe you can flash an international ROM to this phone unless you want a pretty paperweight. But there are some tutorials to unlock your SIM to be able to use on other carriers, here is where I'd start. However if he's on a Knox bootloader I think the chance is next to zero for using it on GSM because you have to 'go back' to MDC to do some required stuff.
If he wanted to use a gs4 on a GSM network he should have gotten a GSM version not a CDMA

It is actually already unlocked as he can use Voice etc just a bit tricky to get the APN settings to work for 3G...
Hi everyone long time reader and I finally got an account. I read through the Sprint section and successfully followed imbmiller's domestic sim unlock guide. I got the sim unlocked but the problem is using a rom like Cyanogenmod, the versions are hard coded to a particular brand. If I download the Sprint release, I dont see any data usage registered (even though it downloads things fine, the data usage keeps saying no data was used), so I was wondering if its ok to install a Tmo rom on a Sprint phone. They are basically the same hardware, right? The TMO rom will simply not use the CDMA bands from sprint, but other than that it should be safe? I have already experimented with this, flashing entire tmobile stock firmware and stock rom on my phone. It actually booted up fine but once it started, I kept getting "com.android.phone has stopped unexpectedly" errors and it was unusable. Later I tried a combination of Tmobile stock rom with a Sprint Kernel and the phone was usuable for a while, and then started crashing constantly. I dont know if it was because I didn't have a working sim card at the time or what, but I am warey of experimenting right now because I must have overwritten the cache/system/firmware partitions at least 20 times and I'm worried about the limited write capacity of emmc.
Now I checked Cyanogenmod's releases and it seems they all use the same kernel, but the rom is just tweaked for each carrier. So to sum up my questions: would I be right to expect no problems in flashing the Tmobile version of CM on my Sprint GS4? And can I flash other Tmo roms on my GS4? Should I expect tmobile firmware to be compatible with the sprint phone, since sprint only has extra features on top of what tmobile phones use?
I would just install the Google play edition like I have on my spring S4. I use T-Mobile Sim and get hspa+ speeds.

Does that really work? When we install the Google Play Edition Rom for Sprint Galaxy S4 Model #SPH-L720
it unlocks domestic GSM function for T-Mobile??
No, you still have to do the SIM unlock separately. But if you then pop in a T-Mobile Sim and install that ROM, according to that it should give service on T-Mobile.
Before I rooted my verizon galaxy s5 I was able to use ATT sim cards but the phone would not get any service whatsoever with a tmobile sim or metro pcs sim. Everyone i spoke to at least was able to connect to the tmobile or metro pcs network, even if they were having data issues...but I was not even able to get a network signal. Finally, I rooted the phone and am using a tmobile rom thinking that may help. But no luck. For some reason my phone will not register itself on tmobile or metro pcs, Not even to just connecto to the network to make phone calls. I tried 2 different tomible roms and i think an att rom and no luck whatsoever. Anybody else experience this issue? Is there a root function or service menu that I need to access to enable the proper band? Is rooting the phone even going to change anything? Makes no sense how every other verizon s5 out there has no problem connecting to tmobile or metro but I have the only one. Ive scoured the forums and have yet to find any answer....thoughts? Oh, I also tried every APN settings combination imaginable. Even other carriers just because I was getting nowhere with the tmobile and metro APNs.
Quite a lot of your thread made absolutely no sense, so I'm not sure if this will help.
Look for a tar.md5 that contains the stock modem partition for the Verizon S5, and flash it through Odin.
Are you bootloader unlocked? I would just flash a generic klte rom, like Cyanogenmod, instead of flashing an ATT or T-Mobile rom.

According to a few people i spoke with the root for verizon s5 can only accept TW roms. And to clear up anything that doesnt make sense. my verizon s5 will not get any service with tmobile or metro. Works fine with att. So i decided to root. After rooting still no luck. However, before I rooted I was getting no bars at all. After rooting I was actually getting service bars but still would not get any actual service. I tried every APN setting I could find and still no luck. Thats all. I will try your advice as far as flashing the tar.md5 and let you know.

There was a bootloader unlock exploit released - it allows any rom to be flashed. It's been in the top development posts for weeks. Go check that out, and you can flash cyanogenmod.
I actually am in a similiar situation except I am already on CM13 using a previously Verizon S5, I just started Tmobile service yesterday and in general I can make calls but data is rather inconsistent. Example right now when I make it call it falls down to 3g (Normal) but when I disconnect it tries to connect to H+ then 3G but all of them don't supply it data so it just swaps around 3G LTE and H+ and I have to airplane mode on/off to fix it. So this person may still have issues using CM13. I did already go over the APN information with people from TMobile and from post around the web. Does anyone think that flashing the Tmobile s5 modem stuff will fix this?
you just need to get the correct APN settings

I've tried the correct son settings. It didn't work. I used the settings found online for T-Mobile. I called T-Mobile. Non of the settings worked. I flashed back the the stock rom. No joy. flashed a verizon s5 rom again. No joy. I am starting to think that this is the only verizon s5 that won't allow t to register on T-Mobile's network.
Four things to note before proceeding...
1. This only works for users having vs985 model outside the US or not on verizon network.
2. I'm beginner im not responsible for any harm to your phone , I'm just sharing what i did to attain 4g services.
3. May be you already know all the things in the post but it can be useful for beginners like me .
4. Sorry for the english as its not my native language.
So Hi guys i installed this rom and as usually i was not getting any 4G or lte network.
Then i go to my network provider's website to check on which Band or frequency 4g services are active. ( for this i just googled 'idea 4g band' and i am redirected to my network provider's website. Here 'idea' is the name of network provider.)
So i found that in my region 4g services are active on Band3
Different careers use different Bands to provide 4g services such as band40 , band17 etc
Then i go to phone's hidden menu by the Advanced Menu of Fulmics Tweaks.
In hidden menu i select Modem Protocol > LTE Band Selection
There i select Band3 but i got "Fail' message on screen , however when i select band4 it gave me a 'success' message.
It means on my phone band4 is active but not band3.
All this information of Bands are stored in Modem or Bootstack section of our phone.
May be fulmics rom is having a band concerned with international rom So now i need a modem on which Band3 can be activated by going to hidden menu.
So i just flashed 35b Bootstack compiled by @xdabbeb.
Which can be found in this thread http://forum.xda-developers.com/verizon-lg-g3/development/xdabbeb-s-vs980-2-0-0-t3231279
After flashing when i tried to select band3 in hidden menu it gave a 'success' message . It means Band3 is activated on my phone. And now when i searched for all networks in Networks Menu of Phone Setting. I got my network listed and i successfully registered on it. And got 4G NETWORK.
So first of all you should know on which band your network is working and then try flashing different bootstacks on which your 4g Band can be activated.
Flashing wrong Bootstack can brick your phone
""Do not flash any bootstack above 35b. Custom roms are still not compatible with bootstacks above 35b""
You can try 24b , 12b. (But im sure only about 35b as i tried only this)
Again I'm not responsible for any harm to your phone. Use your mind and search thoroughly before taking any step.

Hi there, thanks for the info. What area are you in and where did you find what band you needed? I have tried numerous times with all the bootstacks and never had consistent 4G.
@mopartonyg
I'm in India and i just checked my career's website to know which band they are using. However in USA Verizon wireless uses Band12 as Primary Band and Band2 , Band4 as Secondary band to strengthen the signal in densely populated urban area. So if you are verizon user in USA band 12,4,2 must be activated. I can't say anything about consistency as it varies from place to place.
Actually Verizon uses band 13 for it's primary along with bands 4 and 2. Not having any luck getting data to work on Fulmics with this method. I select band 13 and band 4 (as band 2 is not in my area) yet even with that I still can't get data at all on Verizon with Fulmics.
same boat here... actually the only band I can get working is 4. I have to assume the design of the international rom with the band they are designed around, just don't play nice with our CDMA harware/modem partition. I would suspect that the international roms would require some engineering for them to really work properly. not sure if just porting them over and chaning settings is going to get the job done. perhaps someone more intelligent than I could share some light, but there certainly is a conflict with how these roms communicates across the CDMA bands in the US

One thing i noticed here... that only Verizon sim users are facing problem regarding 4G whereas other international users like me ( and some of my friends in China are free to select any network ). So may be verizon is creating restrictions as when i was on Stock vs985 verizon Rom ( unrooted) , i was not getting any official ota updates. It always says your software is up to date. But then i found a statement in Verizon's website that you will not get any official updates if you are not having verizon sim.
So verizon knows what Rom and what sim we are using.

A couple of good approaches to the issue. Although it needs to be noted 4G is directly related to the band on each carrier (VZW, TMO, etc) See Below
Carrier 4G LTE Bands Frequencies
Verizon Wireless 2, 4, 13 1900, 1700 f, 700 c
T-Mobile 2, 4, 12 1900, 1700 def, 700 a
Sprint 25, 26, 41 1900 g, 850, 2500
Europe 3, 7, 20 1800, 2600, 800
If a specific ROM cannot be set to the correct bands above, it would make sense to me that Verizon wouldn't work in Europe on a stock VZW ROM. It would not be able to use the channels in Europe.
And vice versa, that Verizon wouldn't work in the states on an international ROM in the US. Whether the Verizon SIM is blocking that band, or the design of the ROM, would be a better question for the developers.

Warid's approved devices will definitely work with Warid's LTE network. For our "Warid LTE Approved' devices please visit the "Warid's LTE devices" section. You can also purchase LTE devices that support 1800 MHz (FDD-LTE Bands 3) from other sources. However, Warid doesn't take responsibility for these devices if they do not work on Warid's LTE network http://www.waridtel.com/lte/faqs
So it makes sense that if BAND 3 works international (see above) that you get 4G
The one thing I noticed after activating bands 13 and 4 (with the proper VS985 35B bootstack) in the hidden settings is when I searched for my network under network settings it does bring up Verizon but it fails authentication. So it's like there is something missing in Fulmics ROM itself that would get it to where the ROM will work with Verizon's network. So is it a matter of lifting whatever files from say 47A/47B into Fulmics that have the Verizon VS985 specific info to get it to work perhaps?

I think now its not a matter of bootstack. Because even when Required Band is activated we can't register to the Verizon. Xpirt mentioned in a post that he is working to resolve network issues in Verizon models. We can hope that this problem will be solved in next version However xdabbeb shared that the 47A modem won't work without the corresponding 47A secondary bootloader (sbl1). Unfortunately, the 47A sbl1 doesn't play nice with the last bump-exploitable Android bootloader (aboot) we have from 12b. If you use that pairing, you'll put your device into 9008 bulk mode(Hard brick).

The good news is we do have 47A ROMs that are using the 35B modem so there is potential that Xpirt could use that as a source for a fix with the authentication issue. So @xpirt if you need anyone to beta test fixes my VS985 is ready to help!

Great discussion towards the development of the International ROM's for our VS985. I was able to get 4G with Andy's 30A ported ROM...although the signal bars never came up on my phone, I was able to get the 4G speeds. I noticed that the APN XML was filled with Chinese... So for whatever reason and way, my phone was able to grab "somebody's" 4G tower. I'm hoping the RIL (Radio Interface Layer) and libraries were pulled over and perhaps this could provide some more insight to @Xspirit

I am on BlackSoulxxx latest LG G3 Tekcafe v5.3 D85530A-Full G5 ROM. Here's what I did to get the bars with 4g data. I tested it out in areas where there is no cell service and in areas where there is 1x or 3g and the 4g came back. I even made a backup of the ROM wiped and installed another marshmallow aosp rom and others. I then went to restore BlackSoulxxx ROM and 4g signal still came back.
Steps I did.
1. Tot'd back to stock 10b and rooted and installed twrp.
2. Flashed LG_G3_Flash2BackupEFS.zip of the 10b rom.
3. Wiped stock 10b and flashed the 10b G3_EFS_Flashable_Restore.zip that was created from the the LG_G3_Flash2BackupEFS.zip.
4. Flashed BlackSoulxxx rom and after it booted up I had signals but not data until I entered the Verizon APN manually see picture of what to enter. If mobile network is greyed out flash 35b bootstack.
5. I entered the verizon APN and selected CDMA then global I got the 4g icon with signal bars I changed the icon with a buildprop edit.
I just don't get signals while in 1x or 3g but data does work still and it will get 4g again if your in a 4g area. The phone does say T-CDMA 64. Here's a https://drive.google.com/file/d/0B-EyVOQK1xDAa0VmbERXcUlrV1U/view?usp=sharing to change it to Verizon Wireless courtesy of @xpirt.

Great job posting your step by step instructions. I've been able to achieve all of the same on a host of international ROMS however with a couple of caveots. I can either have SMS/MMS working properly, or break SMS/MMS and have internet with signal bars. Question about the file above. This will just modify the header, or will it specifically put you on the Verizon network?
