monsefito, your kernel boots from sd card and runs, but is not able to mount/run rootfs. Please check that the rootfs partition of your sd card is correctly set up. Use SpiegeleiXXL's root directory and copy data and system as described above.
If you get stuck with the android animation you might want to change init.rc in line 104:
mount rootfs rootfs / ro remount
and remove the "ro".
(There might be better solutions, please tell me if this is the case).
