I did it! Good news first. I sshed to coreelec and I ran "reboot update", just like I did when I installed coreelec on it (I found the howto I had followed back then).
On the next boot, and right after that blue tinted screen, it booted from the sd card and reached kodi after a while. I am so excited!
I will work on it sometime this weekend. I will also need to do the same on that testing image that is for s805, once I get the all black mxq in my hands
The bad news is that
- systemd pops a failed service on boot, ethmactool-config.service. No idea what this is.
- when the card is not on the tvbox, it just stops at that blue tinted screen and does not boot to coreelec anymore
I had faced that last issue again when I had tried coreelec from the sd, but I do not remember how I had solved it. Somehow I made it boot back to android, but how?
p.s. That blue tint might be an issue with my old dell monitor. It does not happen at all on the tv.
