[Q] SM-9006v - Using on t-mobile

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

[Q] LTE mode on G900L / Stock G900L Firmware question

Hi, first of all, this phone has been flashed to XtreStoLite ROM, which is based on a G900F firmware. Prior to this, the phone has been unlocked by the shop that the phone was bought. S5 G900L is a Korean model and is meant for the LG U+ network. The phone was able to pick up LTE signal in my country (Brunei).
The phone is unable to pick up LTE signals despite on the Network Mode option, there is an option to select LTE/WCDMA/GSM mode. Is there a code that I can use on the phone dialer so that I can activate LTE?
What I meant is something similar to this: http://forum.xda-developers.com/lg-g3/general/mod-root-activate-lte-g3-t2819387
I have tried to dial ##3282# but it does not do anything. I think it's only for the Sprint S5.
The same goes for:
To tell what Band on: ----
1. ##debug#
2. enter passcode 777468
3. go to LTE engineering menu

As for my next question:
When I flashed a stock G900L firmware from SamMobile, it won't read my SIM card, and it seems that I have to use a LG U+ SIM card from Korea first. How do I make the phone able to read my SIM card from Brunei?
Bump.

- As for secret code ##3282#: First, the secret code format of Samsung is *#xxxx#, not ##xxxx#. Second, to see ALL AVAILABLE secret codes in your device, install Phone INFO ★Samsung★ app > Menu > 'Secret Codes'. That way you will know the code 3282 does exist or not.
- Regarding LTE signal, may be your phone does not have LTE bands that your network currently supports. To check for what LTE bands your phone has, enter *#2263# and select LTE Band Preference to see a list of supporting bands.
- If the required bands are missing, you may want to add it to your phone? Try this thread if any luck.

[Q] galaxy s5 gsm mode fix

Hello, I have a Samsung Galaxy S5, and I can't get the sim to register on network, on GSM mode, but it works just fine on WDCMA, or LTE, and I need the GSM mode at home, because 3G network is only available outside.. I checked the sim into another phone, it works fine on GSM mode, so it's something about my phone... not the sim... can anyone help me solve the problem ? do you have any ideas?
by the way, I tried with many firmwares by now, 4.4.2 and 5.0 ... and still nothing

Please help: Using a Verizon 7 EDGE in a GSM market with new SIM?

How do I get a Verizon S7 Edge to recognize a new GSM SIM? I want to use it on another carrier, and Verizon says it's not SIM-locked/carrier locked but when I put in the new SIM, it's not working.
Factory reset didn't work. Would an Odin flash work? IF not, what would?
Thanks. Not sure if I'm asking in the right place.
Flash the U firmware.
Using odin ^^
Depending on which carrier you are flashing to. You can flash the carrier specific file for whichever carrier you want, for example if you want to use it with T-Mobile you can download the T-Mobile Odin and PIT files to flash and it should work fine. Same with AT&T.
Or do as said above and flash the 935U firmware and it'll work fine. Though with this option there's no carrier extras like VOLTE, or wifi calling as far as I know.
I used another Sim on Verizon firmware. Look somewhere in connection settings. There was smthn about which network you want to use Verizon CDMA or GSM. Now i'm on U firmware.
A t-mobile SIM worked fine for me after entering the new APN settings. For best performance though, flash the U firmware to unlock the bands.

Tab S5e AT&T no LTE after flash US Unlock rom.

I live in Asia, I just buy a Unlocked ATT s5e form local saller.
First, its running AT&T stock rom android 9 code SM-T727A, LTE working fine with local sim card. But i dont like At&t rom because bloatware; locked some feature; cant OTA update.
Then, i flash it with US Unlock rom XAA like SM-T727U via Odin, Tab boot working but no LTE anymore (just H+ icon and HSPAP in information, if i switch to LTE only will lost connect).
Now i flash swap 3 version of rom ATT unlock T727U, US Unlock XAA, US Cellular T7274R, no one can get LTE back.
Ofcourse i cant find stock ATT rom on internet for flash back.
So any one have solution or stock ATT rom let share for me pls.
So after no good at community support for this tablet. I leave this comment for who come behind me.
I need to buy account for download ATT stock rom on internet, then flash it via Odin, LTE is back.
After that, just stay away from T7274R rom (or any CDMA Carrier rom) you will be fine.
I have SM- T727AUCU2CUD1 firmware ( full stock S5e AT&T rom Android 10 Bin2), contact me [email protected].
