Galaxy S5 root issue

So I need to root my S5 after a full reset but it keeps running into problems. I've tried from installing usb drivers to disabling reactivation lock and changing usb ports. I'm on G900F t-mobile variant with stock rom and firmware after a full reset, but no matter what I do it just wont do.

This is the log:
