The network setup was not working properly, and the menu hang for a very long time every time I changed device, and when I got to wifi, it couldn’t scan for networks, so I wanted to wipe the system and start over.
After using the toothpick method for booting into adb and performed a factory reset, because it wouldn’t detect the official SD-card formatted with the newest 2017.03-build when named kernel.img, I now get a
FATAL ERROR: Could not find root filesystem device /dev/vero-nand/root, so I try to boot up the installer from sdcard. It wouldn’t work. I got multiple
failed to mount /dev/block/mmcblk0 on /sdcard by read-only (Device or resource busy) and once in a while
failed to mount /sdcard (No such file or directory). So I tried from a formatted USB-drive, since the SD-card slot is not an option. Furthermore you can’t insert a card straight. I think the slot might be defective. Also, card fall out when you have pushed in the eject mechanism and they slide back to entrance position.
This worked out. Finally I got to the install screen, but now it says
Install failed: could not mount bootfs. So I’m pretty much stuck after hours of different tricks and feel the urge to return this crappy device to the United States instead go for a much cheaper Raspberry-setup.
PS: Why didn’t you think about a power off-button on the remote? Seems quite non-convenient to me, when it seems to booting-capability is fragile after an erroneous shutdown.
