Most of the time, after the update is done, I get a two-tone beep, but sometimes I get a three-tone beep. Is there a difference? Thank you.

If in doubt, you can always re-flash the firmware again. Regards, David Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
