- other smart phone software/drivers like itunes, samsung kies, sony companion can affect flashing, try uninstalling them first
- bad usb wire will make flash unsuccessful. i tried many attemps because of this problem.
- drop down menu is missing after flash, if this happen to you, just do a factory reset.
