I can confirm good file download, drivers on PC are good, I'm using a back USB port, USB cable is BRAND NEW! lol, have Write protection off as well. Tried both fastboot and mfastboot just for good measure. Any thoughts? Do I NEED to have an unlocked bootloader for this? please say no
Also the file shows up as a different size on the fastboot screen, it's over 10mb.
