Subject: [PATCH] In "Write Firmware", as long as a valid file was selected
 once, canceling then selecting an invalid file would pass the valididty
 check. Fixes it, but not sure why it is required as we're supposed to
 overwrite the buffer each time we load a file for flashing - there might be a
 better fix.
