I bought a POTC HUO at Expo this year. I just realized it has very old software (v. 1.15) and I'd like to update to the latest (6.0). However, POTC doesn't appear to have have an option in the menu for USB update (like my ST Pro does). It only has an option for Backup.
So, instead, I tried following the procedure posted on the Stern site (dip sw #8, etc.), but when I power cycle the machine or hit the reset button per the instructions, I just end up with a blank display and it appears to be stuck there. No menu options seem to appear. I can't get to a point where it is asking for a USB to be inserted. Any help or suggestions would be appreciated. As I understand it, POTC was one of the early machines in this regard, so I'm hoping someone with some experience on this can help me out.
