Hi Guys,

Having issue with my yi dashcam. While changing the language from Chinese to English, Got the serial number change from CN to US but now I'm stuck between "System language adaptation fail Access denied" and "Yi see different." Logo.

Any thoughts on how to fix this to go back to CN version and have the camera working?

here are the details of my dashcam.

Any help will be greatly appreciated.
 
Thanks ddr... That looks complicated. Any other solution?
 
If not working after flashing US and CN then only repair via UART because you can't run engmode.

@ddr, looks like the same issue in which engmode SN became invalid. If I remember it right after channge of SN. (blue screen) serial has invalid character. Ive trying flashing using US and CN FW but still error in pic. checking the UART, bit complicated for me. any simple explanation/method? on what I need to have to do UART or any method?

your help is very much appreciated.
