Installing nougat on rooted htc10

[Dom 176]

Hi

First time post so hope this is in the right area.

I've got a UK htc 10 that's rooted with twrp and titanium backup installed.

I'm looking to load the correct nougat ruu and not lose root access as it was a pain to achieve originally.

Can anyone help? Any support would be hugely appreciated. Don't wanna brick it!

Cheers
Dom
