PBP does not boot: broken boot partition

[gimy16]

I commented in another post that I had more or less the same problem; but my PBP won't boot even with SD and USB. Only the orange light was lighting and a black screen.

I got an eMMc to USB adapter and I used this to install Manjaro in the eMMc in another PC. You can try this; my problem was that the eMMc was empty because I probably did something to it.

I hope this is useful for you.
