US GS7-s have locked bootloaders, which means we're unable to downgrade until bootloader keys are leaked or T-Mobile unlocks it for us, which probably will never happen.

Ya I have downgraded from 7.0 to 6.0.1 several times already with no problems. My issue is that Nougat rooted is very laggy so I been trying all sort of fixes like govtuner etc but it is still laggy
anyway, here is attached screenshot of how I downgrade quickly and easily on sm-g930t

I'm running on stock nougat and the phone is speedy, gets ok battery life and I'm really not missing root because I've found ways to make it do what I want. The only thing I miss is TB.
