blurjoey do u have any idea how to change language to English for Xiaoyi Power Black edition?
Serial no starts with CABAA
1080 30fps, F1.8, 130 degree should be Power Black ediiton right?

I done before but should be different model without problem.
Google says got extra file AAA222CCC.txt it does show the serial changed to US but its just stuck showing support@xiayi.com and unable to update the firmware.

Its still works if i change back the serial to CN so its not bricked.
