I have a box with allwinner H3 chip. The box doesn't have sd card slot, it only has 02 usb port and also reset button.
I did try some H3 libreelec firmware on usb drive, but the box refused to boot to libreelec (it didn't appear or response anything on the tv, and the led light of box didn't come up as normal - it's blue when boot to android).
Please kindly advise, how can I let my box boot with ny usb drive, or are there any steps in advance before plug in to the box?
Thank you.
