What is the correct model G900F or G900T?

Hello guys. I am from chile and i am new here and would you mind help me with a problem in my Galaxy S5?

I bought this phone in aliexpress. I guess the hardware is genuine. But the software have some weird thing.

My phone is G900F version. But in the Download mode the version is G900T?? Is that wrong?

Also, in the menu of android recovery system is G900T too. But when i extract the battery i can see Model: G900F

I am not sure what is the correct model, and i think that the software was modified, because Knox is 0x1.

Yesterday, i treid to update the Android from 4.4.2 to 5.0 with Odin using an oficial ROM from Sammobile. I used a ROM G900F, but the process failed every time.

Is the Android Recovery Modified? What is the correct model? I think that correct model is G900F because is appears behind the phone but now i am not sure, and still i cant update to lollipop :(

I wait for your help :)
Thanks:)
