When upgrading the firmware on your PopcornHour A-100 Network Media Tank, you might end up with a hung machine before any operations take place. You’ll know this has happened because your TV screen will go black as soon as you start the process. If this happens to you, there’s a simple solution…remove your custom theme. You don’t have to delete it, just renaming the theme folder form _theme_ to theme and rebooting the A-100 is enough to get you in the firmware updating business. Once you’ve updated, you can safely re-apply your theme and be back in business.
