Problem: 
I just updated my Viavi HST and now the screen is upside down.
Solution: 
Power the HST off and plug in the AC charger. Hold down the SYSTEM button and then turn the power on. When you see a prompt asking you to pick a language let go of the SYSTEM button and press number 1 for English. Press number 7 on the keypad for Rotate LCD. The screen will now be oriented correctly and you can power the unit off and then power on as normal.
