Here's my issue. I have a HB 597ci hd. Purchased a couple years ago. It has been less than a trouble free unit to say the least. I just gave up on sending it in for repairs because after 4 trips I figured that's getting me no where. Anyway on the second trip in for repairs they updated the software and that just opened up a whole new can of worms. So how do I get it back to the original version? Some of you techy gewber's help me put here. Thanks superfly.
