Hello all.
I just created a torrent file including the image. Used it for my SPH-DA120. After writing it, you can update the firmware. AFAIK this is the 1.13 version. To copy the image from MacOS or Ubuntu, use:
dd bs=1048576 if=<path_to>/AVIC.img of=/dev/block/mmcblk0 # adapt to your needs
On windows, it seems you can use win32diskimager.
