I followed the directions and had no issues that i can see. when i booted up the system the only apps and games installed were from the 1.6 update and nothing prior. the instructions said to delete all apps in the media folder which i did and copy everything from the 1.6 update over which i did. I'm sure i did something wrong somewhere just can't tell what. either way the system runs great and i'm greatful for the update. Is it not possible yet to add files via usb? if this has already been asked i apologize. also, will there be a 1.6 base full img?
