I bricked my Yi 4k+ changing fw-it froze and only video record would function. There was the fw update screen but unresponsive. I took a hint from the Ambarella tool kit use to unbrick the xiaomi yi cam or Yi 4k and other SOC's using a .elf file. Since there is no support for the H2 SOC in the 4k+, I went ahead with the card and battery in and the camera on and shorted the rhird contact point behind the face plate . On the third try the camera screen announced update complete . The cam is back to normal. I hope this helps someone.
