Ok, so i downloaded the bootloader and Modem for the 900F and Odin still fails using 3.10.7. I tried 3.09 as well as the guide said.

Download mode:

What are these logs telling us? Is it effectively saying there is an authentication error because the files are not compatible?

Update:
I tried doing one at a time to see if that helped - the modem one nearly passed, but still failed:

Supposing that works, would affect would running a 900T have being in the UK on the Three mobile network?

Since, according to post #20, you are already using the T-Mobile (USA) baseband/modem on Three UK, it should not make any difference. The T-Mobile model, G900T, is compatible with both 3G and 4G/LTE but not U.K. 2G according to, Will My Phone Work?. Check it out yourself by switching to GSM only in Mobile networks.

Make a nandroid backup first.

Thanks, that's a great site for reference. Had a look myself and it appears the only difference is that on the 900T in the UK we do not get signal Band20-800MHz on the 4G LTE Network.

Researching this basically translates to, if I am out and about I am more likely to not get 4G in some areas where I would have had otherwise if I was using the 900F baseband/modem. This is unfortunate, but i think at this point is it reasonable to say that changing the modem/bootloader to the F model is just not possible since i have the T variants on it?
