[Q] Change S4 ATT 4G Band/Frequency - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hello, I have a SGH-i337 (I337UCUAMDL) with Goldeneye 49 ROM sim unlocked
My model has a 4G LTE 700/1700/2100 band/frequency.
But here in my country (Brazil) we use 2.5~2.6MHZ frequency for 4G
The international version (I9505) have the brazilian frequency, so my question is: Can I somehow change the frequency or flash the i9505 modem to my cell phone in order to be able to use my country's frequency?
Thanks!

Sorry, but there's hardware differences between the i337 and i9505. It's not as easy as flashing a modem.

[Q] samsung galaxy 4g modem problem

Hope some one could help... I judt bought a samsung galaxy 4g in the US, the T-mobile version. The problem is that this version hasn´t the 850 Mhz band option, so I can´t use the 3g network wich is by default use by my carrier. I have read that you can change the modem in the other galaxy S versions with froyo. Is it the same procedure for galaxy S 4G... wich modem and rom version do I neeed.
My configuration: SGH-T959v, firmware 2.2.1, Baseband T959VUVKB5, kernel 2.6.32.9
Thanks.

Baseband AWS

Hi, I bought my phone from Hong Kong and I'm from Canada. I use Wind Mobile but my s4 doesn't have the same frequency as it, I need 1700/2100. So I can't connect to Wind Mobile on my phone, only Rogers, Bell, and etc. I am using the GT-I9500 model. My baseband version is I9500XXUAMDE. Build number JDQ39.I9500XXUAMDE. CSC I9500OJVAMDC. I have never rooted any android phones before (completely noob). So I would like some help and clear instructions please and thank you!

Flash GT-I9505G modem with GT-I9505 international Ltd version

Hello all, I was wondering if anyone has found a way to flash GT-I9505G modem with any international GT-I9505 Lte? The reason is to get other lte bands support such as 2600, 1800 etc
Is that possible? Or it is a hardware that is incompatible?
Thanks allot

The GT-I9505G modem isn't compatible with the 2600 band
Sent from my GT-I9505 using xda premium
I will warm this up. Yes, the i9505g modem isn't compatible with 800, 1800, 2600.
But is it somehow possible to activate these bands somehow, as the hardware
would be supporting these bands (a normal i9505 modem is compatible with 800, 1800, 2600).
Anyone has flashed i9505G modem on i9505 with GPEdition ROM? Is it safe?

[Q] Can I flash a international I9505 modem to my I337?

Hi,
I took my I337 AT&T S4 (GE45, boatloader MDL, baseband NI1) to Taiwan and is currently running on Chunghwa Telecom 4G TLE network. But I am not getting the LTE speed because CHT uses band 2 1800mhz while AT&T uses all these other bands beside the 1800mhz.
I want to flash an international version modem like the latest XXUGNG2 so I can get the 1800mhz frequency. Is this doable?
Someone said it's a bad idea to use a modem from a different variant. So would it be better if I flash an I9505 custom rom like Omega or Echo first, and then flash a AT&T suitable kernel than flash the I9505 variant's modem?
Me too but noone help us.

ok, you should be able to flash any G900F tar.md5 file from any country on it. You have the international verison of that phone and it has TONS of tar.md5's for it that will all work just fine. only signal difference you will notice is in the different radios that are in the different tarballs, other than that, they should all work the same
