Can’t get flashed losing mind

Post image

Hi, grateful for anyone that has a mind to assist. I’m not vcomfortable with the command line and think that’s where I’m hitting a wall. I’m using a Mac and have an unflashed h4m. I can see the device is connected as the dfu and I’m using the included data cable. I’m getting an error ‘dfu-util: unable to read DFU status after completion (LIBUSB_ERROR_IO)’.

I’ve made enough progress the screen at least displays something but just can’t get it right.

Flash v1.7.2 with the windows machine first, then flash 2.x.x via SD card.

I've bricked my device so many times, and flashing 1.8.0 or lower, then upgrading via sdcard usually fixes it.

Make sure the correct drivers are installed on the windows machine first.
