Reboot phone and try again.
Check ADB drivers, USB cable. Don't use USB Hubs
If this repeated then reflash phone and make factory reset.

Hello, please try to flash modem from

COMBINATION_FAC_FA90_G975USQU2ASF1.zip or

G975USQU2ASF6_OYN2ASF6_VZW.zip

And after that read codes again, server will not charge twice for the same phone.

In case if double credits taken, write here and we'll refund.
