Extract FW96580A.bin to the root of the SD Card, and insert it back to the dashcam,
Power the dashcam on, and it will take 20-30 secs for the flash process to complete.
during the flashing process it will not show anything on the screen, only blue light will be flashing which means the firmware flashing is in process, and once the flashing is done a solid red light will be shown and it will restart once the process is completed.
after the successful booting, you should have an english version in the dashcam, you can use the international 70mai app from play store to connect and setup your dashcam.
