I dusted off a old n9 that still works and trying to flash in updates. I have winflasher 3.12.1 on windows 7 computer, command window opened as admin. ran the command first and then plug in the N9 that's off and fully charged.

Long story short. the N9 will simply go back to charging mode.

The U.S.B cable works since if i turn the phone on, windows will detect the phone and i can use it as USB device. yet I can never get winflasher to connect to it.

any ideas?
