I have installed Ubuntu directly of the flash of the Mk802 iv, everything worked without any issues. I needed to move the mk802 iv elsewhere in the house and I decide to power off via ssh (sudo halt) and after..... no BOOT, not possible to switch in programming mode.
The only thing working on the mk802 iv : the red light (via hdmi : blank image, via usb : no detection!
But I see nothing for this version to erase the flash with a short between 2 pins.
Do you have a tips before Halloween ?
Thanks in advance,
