Hi folks

I'm reading the guide on how to downgrade my Mi Box and getting a little stuck.

I can boot into recovery mode fine - that works.
If I turn on USB debugging in the interface, I can adb to the box using USB A to USB A - that works.

I load the firmware image into the USB burning tool, and I start up recovery mode.
I then pull the power out the back and hold down back and ok button and put power back in - all that happens is I get back to the recovery menu again - nothing on the USB burning tool starts up.

I read something about maybe shorting pins inside - Does anyone have any info on this, or is there any other way of applying the firmware?

Thanks everyone
