I tried to install to internal with SSH. Now X96 works without SDcard.
But when I try to go back to Android it is not possible anymore. I have used a toothpick for the resetbutton in AV port. X96 Boot logo appears. But TWRP recovery does not start and Internal recovey do not start. It only hangs in Boot logo. I tried via SSH command reboot recovery. Again X96 logo appears but hangs in it. Is there another possibility to install Android again?
