Sorry for the late reply, but I wanted to try flashing the software using another computer that has never had kies, Verizon, or Samsung programs ever downloaded on it, also I disabled firewall and antivirus when trying to flash but I still keep getting
ERROR: failed to access device libusb error: -12
Could it still be a program that I forgot to download or something I forgot to add?
