Hi,
I’ve got my hands on an DV6067Y from SDMC, based on an S905Y2 SoC. It boots the latest 9.2.5 stable from an USB drive, which works pretty fine (although USB seems to be a bit slow). Now I’ve tried to install CE to the eMMC, which SEEMS to work at first:
ceemmc -vx

Success!
You can now power off the device, remove the used boot media (SD or USB) and
power on again to boot the device from eMMC!
After restarting and pulling the USB drive, the device just displays a black screen, not booting from eMMC, no error, nothing…
I noticed that if I restart and boot from USB again, ceemmc doesn’t detect a CE installation on the eMMC:
No CoreELEC installation found on eMMC
Also if I try use ceemmc twice wothout rebooting, I get the following error:
eMMC size: 0x0001d2000000 [8GB]
Partition '/dev/reserved' does not exist!
Failed to read original partition table!
Don’t know if that gives any clue about what’s the problem here.

I just wanted to try eMMC because USB it’s kinda slow on this device. I don’t think there will a way to unlock the bootloader because the device is sold rebranded (MegantaTV Stick) as a Fire TV competitor by a big german telephone company/ISP.
