Hello
I'm thinking of buying the international Galaxy S4 i9505 and use it on T-Mobile here in the USA (rather than the T-Mobile m919 variant) ...I am aware that i9505 doesn't have HSPA on AWS band and that's fine because most of my area has T-Mobile LTE which works on the 1700/2100 MHz band (band 4)...
Does anyone from the USA use i9505 on T-Mobile and get LTE ?
Another thing, is it possible to flash m919 radio on the international i9505 to have the lacking LTE bands if any ?
A note : according to gsm arena,i9505 has APQ8064T but couldn't find what chipset the T-Mobile m919 has...If they use the same chipset it would be likely possible to interchange radios between the 2 I suppose...
Any ideas are welcomed..
Thanks
I am in same situation.
We need answer about this From the user or developer who has Experience with this case.
Best Regard to all
any help???
I9500 is the international version, i9505 is the US version

The is not what we want to know.
Will m919 modem work on i9505 ?
It is not wise to flash another carriers modem, but yes, you can.

Recovery, go get the modem you want from tmo forum. and flash it, I do not think it is a good idea, but if you feel it is needed. So be it.
Thanks for the Thanks.
DO NOT flash modems. Flashing modems to enable frequencies has NOT worked on S3, Note2, S4 i337. Don't do it.
"You don't think" doesn't mean "it's not possible" or "a disaster will happen"
I used my skyrocket on T-Mobile after flashing a T-Mobile radio from Hercules (very closely related device to skyrocket... both are s2 variants)....
So please stop the useless advice of not recommended, or not advisor or such... It's xda not Facebook..
If 2 devices has the same chipset and/or the same hardware platform it could be very likely that the only difference between then is the radio software and the commercial name,. Unfortunately I couldn't find enough detailed (deep hardware details) info on the T-Mobile S4...
The main purpose here from this thread is that did anybody here try it and connected to T-Mobile LTE in USA successfully ?
Any update??

I would also like to know if the i9505 can connect to T-Mobile's LTE in refarmed areas. I'm holding out on the purchase right now but if it does work then I'll go ahead and buy 1.
As I understand it, I don't believe that the I9505 can connect to Tmo's LTE frequencies but it should probably get unto the refarmed (1900 mhz) 3g areas if you're in one of the big cities (ie; NYC, LA).
It looks from the specification that out of the box it will not work..It doesn't have the 1700mhz LTE band(which T-Mobile USA uses for the LTE uplink)..
For sure it'll need some"modding" or radio flash to work...
We need a guinea pig big-time here lol..Probably somebody buys it, flash the S4 M919 radio on it and report back...If it doesn't, ship it back to seller for a refund...
PS: it is useless if it won't connect to T-Mobile LTE(i.e. just 3G)..Pretty much everywhere will get LTE eventually...
We are still waiting for real Solution.............
so is it mainly coming down to the radio thats built into the chipset and not the software side of things, I wanted to flash the modem but I dont know if it will brick, blow up, or turn into optimus prime.... any ideas lads,
cheers

You have I9505 ? Are you on t mobile ? Do you have a good return policy for the device ? And in the return period ?
If so and you're brave enough, look for a flashable m919(T-Mobile S4) radio zip and flash it using any custom recovery ...Beware that this action might corrupt its imei or might cause a big problem that can't be corrected easily... So you're responsible for that ... But if successful you'll be able to use T-Mobile LTE and do the community a great service...,
Please let us know if you have any updates.
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.
:/ .
Hi,
I just purchased a Galaxy s5 sm-g9006v. This is the chinese unicon Samsung galaxy s5. It's unlocked.
I have a t-mobile sim. The phone works fine but the only problem is that it's only running 2g speeds! and i've been reading and i think it's a problem with the bands the phone is working on.
I've also been reading about changing the firm-ware modem but I need a little help.
My question :
Can I change the bands that my phone is using to t-mobile compatible bands to run hspa+ or lte or 4g ?
If so, is it as simple as flashing flashing t-mobile firmware from sammobile (sm-g900t) to my phone via odin?
And if I can fix it without having to flash the whole original firmware by just flashing the modem (which is 5mb), where can i get the modem for that firmware and how do I flash it alone ?
Thank you
Hello,
I have a 900T that I am using on ATT network.
Where is the ATT modem that I can install?
It currently has the T-Mobile NK2 baseband.
thanks haeffnkr
You don't need to install an att modem. Just update the APN and you're good to go (assuming your phone is unlocked)
Hi,
Yes I am getting connected to the ATT network with tmobile modems but....
I am getting download speeds under what my ATT S4 was doing and my signal drops from time to time.
I would really like to use the ATT modem and see what difference it makes.
Does anyone have a link the the ATT S5 modems?
thanks haeffnkr

Hello,
You can either extract them from the stock ROM or search the SM-G900A forums.
I did a quick search and got this
http://forum.xda-developers.com/showthread.php?t=2868904
thanks I did not find that when I searched.
Any chance you can find the - G900AUCU2AOA1 version
thanks again haeffnkr
i know n910C is not for USA, but here I am using N910C in USA on Tmobile network
and i am having issue with weak network/signal at many places
and i was wondering if there is a way i can install Tmobile modem/bootloader on N910C.
I already downloaded tmobile modem and bootloader and tried to install using odin,
but it fails everytime.
any help please
thanks
i have an n910H. by default, its set on 3g, metropcs lte. then ill just register it to a tmobile network. i guess my version cant get lte so the highest i get is H+. which is still as fast as lte, at least to me. and im using tmobile.
You cannot flash tmobile modem or bootloader only thing to do is buy a tmobile branded phone
