Hi Everybody,
I’ve just installed OSMC on the HDD of the ATV and it’s not really difficult, for thos who are interested in!!
1 - take the HHD drive of the ATV or another HDD of 40gb
2 - put in a usb / ATA controller adaptater.
3 - Install OSMC on it with the SD card option and the HDD img.
4 - Once done, put back the HDD on the ATV and let it install.
5 - Do the update and be carful not interrupted, it take a couple of time…
Thanks to Sam and the team for given a new ATV life.
