Issue booting OSMC (rainbow screen)

@FunckThomas

SD card is not locked there either. I can easily see the unpacked files on the SD from the IMG file… Both when i try on the Mac and PC… I’m not new to this, i have done this 100 times with other RPI distri with no problems and with same unpacking procedure…

Yes, we understand that. But than you have thread jacked as the problem of @r3ndar is different.
I will move your posts to a new thread.
