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

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.
:/ .
I bought my GS5 from Canada which means it's set on canadian LTE bands, now I'm trying to use my phone in UK and it doesn't connect to data network, not even HSPA so I was thinking that flashing a UK firmware might solve the problem because I read somewhere that since GS5 runs on Qualcomm its hardware supports all LTE bands by default but I am still afraid that the wrong firmware might brick my device. Can anyone please confirm that information. thx a lot
As long as that firmware is supported by your specific GS5 model this should not be a problem.
I live in South Africa and have flashed many stock firmwares from different countries.
Just a note... you might not have to reflash the entire ROM but merely flash a supported modem/change the csc. Changin the csc does however factory reset your phone.
Yes but a different csc file from the stock rom version will prevent the phone from receiving ota update. Anyway it's not my phone so I won't take any risks and the owner seems to be fine with hspa connection.
Search sammobile.com for the phone model and stock firmware from UK. Just flash that and then you won't have to change the csc

Hi there,
Im not sure if this was discussed about this particular situation.
I recently switched from Wind mobile to Fido which offers LTE connection. Unfortunately Wind disabled Lte network mode And the only mode I can connect to is 3g.
I have rooted the phone and tried various methods on how to enable LTE
including guide on xda how to enable all bands.
The only thing i have not tried is flashing new modem firmware.
Here is my question:
1. Would flashing new modem firmware enable lte network mode?
if so which modem firmware should i use and is there a guide?
2. Would upgrading to new rom solve the issue?
Please help me, thank you for any suggestions.

Anyone?
U can use videotron or Unknow Firmewire on Sammobile u will get LTE enable already
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

Hi,
I had bought a Canadian s4 on ebay with version 4.4.2, I had root it for unlock the Italian language, and worked fine for two years but without ever receiving the H + and H bands, he was always on LTE or 4G...
A month ago I decided to do an upgrade it and factory reset because te phone had become very slow, so after total wipe I downloaded the stock Lollipop I337MUMUGOH3 Trinidad & Tobago (because unlocked and more native language) and flash it with Odin, but after the softkeys have not worked ... I tried some other stock rom without succes, with I337MUMUFNE2_I337MUUBFNE2_TTT 4.4.2 the touch is coming back to work even if typing * # 2663 # the phone shows fw version is 0x10 and the part's fw version is 0x1a and can't get touch fw update (IC's F/W is higher than Bin's F/W), but I lost LTE bands, now working bands are always H and H+ and never LTE or 4G ....
I tried to install different modems taken from other stock rom, but without success ...and QPST show me all bands enabled...
Maybe i must change the baseband ??? Witch baseband? And how can i do it??
How can I get back the lte without losing softkey? And how can update the softkey fw?
I do not know what else to try :crying::crying::crying:
Thanks in advance..
I recommend not trying to flash the AT&T s4 sgh-i337 firmware to the Canadian s4 sgh-i337m. If you are able to flash the stock AT&T firmware onto the Canadian s4, you will have a locked bootloader.
Did you change your cell provider? Does the sim card get LTE in another phone?
You can flash the stock Canadian LP ROM from sammobile.com to see if the buttons work properly.
I recommend not upgrading the touch firmware at all as there is a chance it will disable all touch functions.
But my model phone is SGH-I337M!!

The sgh-i337m does not have a locked bootloader. The AT&T s4 has a locked bootloader so flashing at&t firmware to your Canadian s4 could result in a locked bootloader or a bricked phone.
There are no stock ROMs for the at&t s4 above 4.1.2 from sammobile.com like there is with the Canadian version.
It's up to you If you want to flash AT&T firmware to the Canadian s4.

I'm confused, I need some advice how to restore lte bands on my phone without broke the softkey, I did not say want to flash the ATT firmware....
Some ideas?
I apologize for referencing the AT&T firmware. I misread your original post.
Have you tried flashing firmware for a Canada. It doesn't matter whether your flash firmware for Rogers, Telus, or Bell as long as it is at least version OH3.

But the Canadian firmware not work properly in Italy, I used it for 2 years without H bands, the TTT firmware is for the same phone but is open, maybe I must change the csc?
I suggested flashing the Canadian firmware to see if the firmware fixes the problem with soft keys. Once that is fixed, you can try other fixes to get lte.
You can flash the stock Canadian lollipop ROM and change the csc by dialing *#272*imei#.
