@chloe-zhao : can you please help me out with my aurora Cc? I made an update from YouTube and now I get the warning message:" This product is not a xgimi official international version product, so the international firmware is not proper functioning". what can I do? How can I use the projector normally? Can I do another software update? Where can I find the download firmware? Machine Name: CCM3KE9BEXWG. Thank you!
