Skipo, looks like we have the same problem. I also have the 4.4 and Openelec 6 Sd card.
My device already been working with toothpick method.
today I tried this :
downloads for Amlogic MXQ TV Box by Demetris. | AndroidFileHost.com | Download GApps, PA GApps, Roms, Kernels, Themes, Firmware and more. Free file hosting for all Android developers
without any toothpick, it loaded to LE , the android 4.4 was not hurt and I could switch to it with shutdown: boot internal.
what we were looking for was same image from Balbes150, which is compatible.
