After running the script that stopped with the flashing, I did a flash from my pc with:
flasher-3.5 --enable-rd-mode --set-rd-flags=no-lifeguard-reset,no-ext-wd -f -k NIT-zImage -R

I had to create the bootmenu file. It wasn't created with the script.
Android came up on first boot. I thought I saw something about it had to reboot a couple of times before it would start....
The wifi worked and connected to my WLAN.
I tried youtube but always got the message cannot play video...
