Which version is mine?

In Setting - About device it say SM-G900F

But in bootloader it say SM-G900T

I just noticed this when I failed to flash BOOTLOADER/MODEM Package using SM-G900F

Previously I installed TWRP for SM-G900F. Or is it TWRP is for any version?

Should I use BOOTLOADER/MODEM for SM-G900T? Would it brick my phone?

Thanks.
